abstract: OBJECTIVE To evaluate the effectiveness of a worksite health promotion program on improving cardiovascular disease risk factors . METHODS In St Louis , Missouri from 2005 to 2006 , 151 employees ( 134 F , 17 M , 81 % overweight/obese ) participated in a cohort-r and omized trial comparing assessment s + intervention ( worksite A ) with assessment s only ( worksite B ) for 1 year . All participants received personal health reports containing their assessment results . The intervention was design ed to promote physical activity and favorable dietary patterns using pedometers , healthy snack cart , WeightWatchers(R ) meetings , group exercise classes , seminars , team competitions , and participation rewards . Outcomes included BMI , body composition , blood pressure , fitness , lipids , and Framingham 10-year coronary heart disease risk . RESULTS 123 participants , aged 45+/-9 yr , with BMI 32.9+/-8.8 kg/m(2 ) completed 1 year . Improvements ( P < or = 0.05 ) were observed at both worksites for fitness , blood pressure , and total- , HDL- , and LDL-cholesterol . Additional improvements occurred at worksite A in BMI , fat mass , Framingham risk score , and prevalence of the metabolic syndrome ; only the changes in BMI and fat mass were different between worksites . CONCLUSION A multi-faceted worksite intervention promoted favorable changes in cardiovascular disease risk factors , but many of the improvements were achieved with worksite health assessment s and personalized health reports in the absence of an intervention Background Worksite nutrition and physical activity interventions are important to help overweight and obese employees lose weight , but costs and insufficient sustained motivation prevent the majority of these programs from succeeding . Tailored text messaging in aiding weight management has been effective in several studies , but no studies have evaluated the effect of a tailored text message service on weight loss in a worksite health promotion program . Objective We studied the efficacy of a tailored text-messaging intervention for obese male participants in a worksite weight loss program of 6 months duration . Methods The study was an unblinded , r and omized controlled trial . Men with a body mass index greater than 25 kg/m2 were recruited from the Korea District Heating Corporation , the Korea Expressway Corporation , and the Korea Gas Corporation . The participants were identified by nurse managers . Participants were r and omly allocated to 1 of the following 2 groups for 24 weeks : ( 1 ) intervention group , which received tailored text message reminders every other day plus 4 offline education sessions and brief counseling with monthly weight check by nurses for weight control over 6 months and ( 2 ) control group , which received the 4 offline education sessions and brief counseling with monthly weight check by nurses about weight control over 6 months . The primary outcome was the difference in weight loss at 6 months . A mixed-model repeated- measures analysis was performed to evaluate the effect of the intervention group ’s weight loss compared with the control group . Results A total of 205 obese men were r and omized into either the intervention ( n=104 ) or the control group ( n=101 ) . At the end of 6 months , the intervention group ( n=63 ) had lost 1.71 kg ( 95 % CI –2.53 to –0.88 ) and the control group ( n=59 ) had lost 1.56 kg ( 95 % CI –2.45 to –0.66 ) ; the difference between the 2 groups was not significant ( mean difference –0.15 , 95 % CI –1.36 to 1.07 ) . At the end of the study , 60 % ( 34/57 ) of the intervention group rated the message program as helpful for weight control and 46 % ( 26/57 ) would recommend the text message service to their friends . Conclusions Tailored text message reminders did not have a significant effect on weight loss in obese men as part of a worksite weight loss program . Trial Registration International St and ard R and omized Controlled Trial Number ( IS RCT N ) : 39629189 ; http://www.is rct n.com/IS RCT N39629189?q=39629189&filters=&sort=&offset=1&total Results = 1&page=1&pageSize=10 & search Type = basic- search ( Archived by WebCite at http://www.webcitation.org/6VsFkwJH6 ) Background Young women are a group at high risk of weight gain . This study examined a range of perceived personal , social and environmental barriers to physical activity and healthy eating for weight maintenance among young women , and how these varied by socioeconomic status ( SES ) , overweight status and domestic situation . Methods In October-December 2001 , a total of 445 women aged 18–32 years , selected r and omly from the Australian electoral roll , completed a mailed self-report survey that included questions on 11 barriers to physical activity and 11 barriers to healthy eating ( relating to personal , social and environmental factors ) . Height , weight and socio-demographic details were also obtained . Statistical analyses were conducted mid-2003 . Results The most common perceived barriers to physical activity and healthy eating encountered by young women were related to motivation , time and cost .  Women with children were particularly likely to report a lack of social support as an important barrier to physical activity , and lack of social support and time as important barriers to healthy eating . Perceived barriers did not differ by SES or overweight status . Conclusions Health promotion strategies aim ed at preventing weight gain should take into account the specific perceived barriers to physical activity and healthy eating faced by women in this age group , particularly lack of motivation , lack of time , and cost . Strategies targeting perceived lack of time and lack of social support are particularly required for young women with children AIMS To investigate a virtual assistance-based lifestyle intervention to reduce risk factors for Type 2 diabetes in young employees in the information technology industry in India . METHODS LIMIT ( Lifestyle Modification in Information Technology ) was a parallel-group , partially blinded , r and omized controlled trial . Employees in the information technology industry with ≥3 risk factors ( family history of cardiometabolic disease , overweight/obesity , high blood pressure , impaired fasting glucose , hypertriglyceridaemia , high LDL cholesterol and low HDL cholesterol ) from two industries were r and omized to a control or an intervention ( 1:1 ) group . After initial lifestyle advice , the intervention group additionally received reinforcement through mobile phone messages ( three per week ) and e-mails ( two per week ) for 1 year . The primary outcome was change in prevalence of overweight/obesity , analysed by intention to treat . RESULTS Of 437 employees screened ( mean age 36.2 ± 9.3 years ; 74.8 % men ) , 265 ( 61.0 % ) were eligible and r and omized into control ( n=132 ) or intervention ( n=133 ) group . After 1 year , the prevalence of overweight/obesity reduced by 6.0 % in the intervention group and increased by 6.8 % in the control group ( risk difference 11.2 % ; 95 % CI 1.2 - 21.1 ; P=0.042 ) . There were also significant improvements in lifestyle measurements , waist circumference , and total and LDL cholesterol in the intervention group . The number-needed-to-treat to prevent one case of overweight/obesity in 1 year was 9 ( 95 % CI 5 - 82 ) , with an incremental cost of INR10665 ( £ 112.30 ) per case treated/prevented . A total of 98 % of participants found the intervention acceptable . CONCLUSIONS A virtual assistance-based lifestyle intervention  was effective , cost-effective and acceptable in reducing risk factors for diabetes in young employees in the information technology industry , and is potentially scalable Purpose . To evaluate the effectiveness of FUEL Your Life , a translation of the Diabetes Prevention Program for worksites . Design . A r and omized control group design was conducted in five worksites of a large transportation company . Measures were collected pretest , posttest ( 6 months ) , and follow-up ( 12 months ) . Setting . Railroad maintenance facilities of Union Pacific Railroad . Subjects . Participants consisted of 362 workers ( 227 treatment , 135 control ) . Intervention . FUEL Your Life was translated from the Diabetes Prevention Program to better fit within the context of the worksite . The primary difference was the use of peer health coaches to provide social support and reinforcement and an occupational nurse to provide lesson content ( six sessions of 10 minutes ) to participants instead of the lifestyle coaches employed by the Diabetes Prevention Program , result ing in a less structured meeting schedule . Measures . The primary outcomes were weight and body mass index ( BMI ) , with secondary outcomes including eating behaviors , physical activity , and social support . Analysis . Latent growth modeling was used to measure changes in the outcomes over time . Results . Participants in the intervention group maintained weight/ BMI ( –.1 pounds/–.1 BMI ) , whereas the control participants gained weight/ BMI ( + 2.6 pounds/+.3 BMI ) , result ing in a statistically significant difference between groups . Fifty-five percent of intervention participants lost some weight , whereas only 35 % of the control group lost weight . Conclusions . FUEL Your Life , a low intensity intervention , was not effective for promoting weight loss , but was effective for helping workers maintain weight over a 12-month period OBJECTIVES We assessed the effects of a  worksite multiple-component intervention addressing diet and physical activity on employees ' mean body mass index ( BMI ) and the percentage of employees who were overweight or obese . METHODS This group-r and omized trial ( n = 3799 ) was conducted at 10 worksites in the northeastern United States . Worksites were paired and allocated into intervention and control conditions . Within- and between-groups changes in mean BMI s and in the percentage of overweight or obese employees were examined in a volunteer sample . RESULTS Within-group mean BMI s decreased by 0.54 kilograms per meter squared ( P = .02 ) and 0.12 kilograms per meter squared ( P = .73 ) at the intervention and control worksites , respectively , result ing in a difference in differences ( DID ) decrease of 0.42 kilograms per meter squared ( P = .33 ) . The within-group percentage of overweight or obese employees decreased by 3.7 % ( P = .07 ) at the intervention worksites and increased by 4.9 % ( P = .1 ) at the control worksites , result ing in a DID decline of 8.6 % ( P = .02 ) . CONCLUSIONS Our findings support a worksite population strategy that might eventually reduce the prevalence of overweight and obesity by minimizing environmental exposures to calorically dense foods and increasing exposures to opportunities for energy expenditure within worksite setting Background U.S. adults are at unprecedented risk of becoming overweight or obese , and most scientists believe the primary cause is an obesogenic environment . Worksites provide an opportunity to shape the environments of adults to reduce obesity risk . The goal of this group-r and omized trial was to implement a four-component environmental intervention at the worksite level to positively influence weight gain among employees over a two-year period . Environmental components focused on food availability and price , physical activity promotion , scale access , and media enhancements . Methods Six worksites in a U.S. metropolitan area were recruited and r and omized in pairs at the worksite level to either a two-year intervention or a no-contact control . Evaluations at baseline and two years included : 1 ) measured height and weight ; 2 ) online surveys of individual dietary intake and physical activity behaviors ; and 3 ) detailed worksite environment assessment . Results Mean participant age was 42.9 years ( range 18 - 75 ) , 62.6 % were women , 68.5 % were married or cohabiting , 88.6 % were white , 2.1 % Hispanic . Mean  baseline BMI  was 28.5 kg/m2 ( range 16.9 - 61.2 kg/m2 ) . A majority of intervention components were successfully implemented . However , there were no differences between sites in the key outcome of weight change over the two-year study period ( p = .36 ) . Conclusions Body mass was not significantly affected by environmental changes implemented for the trial . Results raise questions about whether environmental change at worksites is sufficient for population weight gain prevention . Trial Registration Clinical Trials.gov : OBJECTIVE To describe the effectiveness , reach and implementation of a weight  gain  prevention intervention among public school employees . METHOD A multi-level intervention was tested in a cluster r and omized trial among 782 employees in 12 central Massachusetts public high schools from 2009 to 2012 . The intervention targeted the nutrition and physical activity environment and policies , the social environment and individual knowledge , attitudes and skills . The intervention was compared to a material s only condition . The primary outcome measures were change in weight and body mass index ( BMI ) at 24-month follow-up . Implementation of physical environment , policy and social environment strategies at the school and interpersonal levels , and intervention participation at the individual level were assessed . RESULTS At 24-month follow-up , there was a net change ( difference of the difference ) of -3.03 pounds ( p=.04 ) and of -.48 BMI units ( p=.05 ) between intervention and comparison conditions . The majority of intervention strategies were successfully implemented by all intervention schools , although establishing formal policies was challenging . Employee participation in programs targeting the physical and social environment was maintained over time . CONCLUSION This study supports that a multi-level intervention integrated within the organizational culture can be successfully implemented and prevent weight gain in public high school employees OBJECTIVES This study tested a feasible method for screening for cardiovascular risk at the worksite and investigated the effects of a long-term comprehensive program of life-style intervention to prevent cardiovascular disease . METHODS Employees in the public sector filled out a self-administered question naire with questions on social , medical , and work-related factors . The respondents numbered 454 ( 80 % ) . A score sum for cardiovascular risk was calculated ( range 1 - 20 , median 7.0 ) , and the 128 subjects with a sum above 8 were invited to a health examination including blood sampling . Thereafter the subjects were invited to participate , following r and omization , in a comprehensive , 18-month , life-style intervention program to improve cardiovascular risk or in a control group . RESULTS The intervention group significantly decreased body mass index , diastolic blood pressure , heart rate , low-density lipoprotein ( LDL ) cholesterol , and smoking habits during the intervention . The initially elevated serum cortisol , as a marker of stress reaction , normalized in the intervention group . In the control group LDL cholesterol also decreased , but the glucose and triglyceride levels increased , and smoking habits were unchanged . Sick days for a given period decreased after 1 year in the intervention group but not in the control group . CONCLUSIONS Several cardiovascular risk factors can be improved and morning serum cortisol normalized during a long-term life-style intervention program with a r and omized design using a worksite population of middle-aged subjects . The use of a 2-step screening program , with an initial question naire followed by a health check of subjects with elevated risk , is feasible for worksite setting OBJECTIVE To present the effects of a relatively modest environmental intervention on biological cardiovascular risk indicators . METHOD A controlled trial , including two worksites . Measurements ( i.e. , body composition , blood pressure and serum cholesterol ) took place at baseline and at 3- and 12-month follow-up . The 12-month environmental intervention ( The Hague , The Netherl and s , 2004 ) consisted of : a ' Food'-part : to stimulate healthier food choices by means of product information in the canteen , and a ' Steps'-part : focused on stimulating stair use by means of motivational prompts in staircases and on elevator doors . RESULTS Significant differences in change between groups ( n=540 ) in favor of the intervention group were found on : [ 1 ] total cholesterol for women ( -0.35 mmol/l ) ; [ 2 ] HDL for men at 3 months ( 0.05 mmol/l ) and 12 months ( 0.10 mmol/l ) ; and [ 3 ] the total-HDL ratio for the total intervention group at 3 and 12 months ( -0.45 mmol/l ) . Both groups showed a decrease in all body composition values at both follow-ups . A significant difference in change in systolic BP was found in favor of the control group ( approximately 4 mm Hg ) , due to an increase in the intervention group at both follow-ups . CONCLUSIONS Based on the contrasting results , this modest environmental intervention was ineffective in reducing cardiovascular risk in a population of office workers Purpose : To determine the effects of an environmental intervention on obesity , disease risk factors , and dietary intake in an employee population . Design : R and omized controlled community trial . Setting : Eight manufacturing companies in Kentucky with ~ 150 to 350 employees each . Subjects : R and omly selected employees . Intervention : Multicomponent environmental intervention that included employee advisory committees , point-of-decision prompts , walking paths , cafeteria/vending changes , and educational material s. Measures : Height ; weight ; body fat ; blood pressure ; fasting lipids , glucose and insulin ; and dietary intake were assessed prior to and 3 , 6 , and 12 months after initiation of the intervention . Analysis : Mixed-model repeat-measure analyses of covariance were used to analyze data collected over the study period . Categorical data were analyzed in contingency tables . A p value of .05 was used to judge statistical significance . Results : There were no intervention effects for outcome variables , with the exception of lower intake of saturated fat and dietary cholesterol in the intervention group compared to the control group . Over the course of the study , changes in anthropometry and bio measures were similar in both groups . Conclusions : Findings indicate that subtle environmental changes alone may not impact employees ' weight and health ; however , such institutional-level approaches may be essential to support healthy lifestyle habits that are initiated by more intensive efforts . Academic research ers should continue to partner with employers and practitioners to develop , implement , and evaluate innovative health promotion strategies including environmental interventions . ( Am J Health Promot 2011;25[5]:334 - 340 . Cardiac rehabilitation and exercise training ( CRET ) provides health risk intervention in cardiac patients over a relatively short time frame . Worksite health programs offer a unique opportunity for health intervention , but these programs remain underused due to concerns over recouping the costs . We evaluated the clinical efficacy and cost-effectiveness of a 6-month worksite health intervention using staff from CRET .  Employees ( n = 308 ) and spouses ( n = 31 ) of a single employer were r and omized to active intervention ( n = 185 ) consisting of worksite health education , nutritional counseling , smoking cessation counseling , physical activity promotion , selected physician referral , and other health counseling versus usual care  ( n = 154 ) . Health risk status was assessed at baseline and after the 6-month intervention program , and total medical cl aim costs were obtained in all participants during the year before and the year after intervention . Significant improvements were demonstrated in quality -of-life scores ( + 10 % , p = 0.001 ) , behavioral symptoms ( depression -33 % , anxiety -32 % , somatization -33 % , and hostility -47 % , all p values < 0.001 ) , body fat ( -9 % , p = 0.001 ) , high-density lipoprotein cholesterol ( + 13 % , p = 0.0001 ) , diastolic blood pressure ( -2 % , p = 0.01 ) , health habits ( -60 % , p = 0.0001 ) , and total health risk ( -25 % , p = 0.0001 ) . Of employees categorized as high risk at baseline , 57 % were converted to low-risk status . Average employee annual cl aim costs decreased 48 % ( p = 0.002 ) for the 12 months after the intervention , whereas control employees ' costs remained unchanged ( -16 % , p = NS ) , thus creating a sixfold return on investment . In conclusion , worksite health intervention using CRET staff decreased total health risk and markedly decreased medical cl aim costs within 12 months Objective To determine the effectiveness of an individually-targeted Internet-based intervention with monetary incentives ( INCENT ) at reducing weight of overweight and obese employees when compared to a less-intensive intervention ( Livin ’ My Weigh [ LMW ] ) 6-months after program initiation . Design and Methods Twenty-eight worksites were r and omly assigned to either  INCENT  or LMW conditions . Both programs used evidence -based strategies to support weight loss . INCENT was delivered via daily e-mails over 12 months while LMW was delivered quarterly via both newsletters and onsite educational sessions . Generalized linear mixed models were conducted for weight change from baseline to 6-month post program and using an intention-to-treat ( ITT ) analysis to include all participants with baseline weight measurements . Results Across 28 worksites , 1,790 employees ( M=47 years of age ; 79 % Caucasian ; 74 % women ) participated . Participants lost an average of 2.27 lbs ( p<0.001 ) with a BMI decrease of 0.36 kg/m2 ( p<0.001 ) and 1.30 lbs ( p<0.01 ) and a BMI decrease of 0.20 kg/m2 ( p<0.01 ) in INCENT and LMW , respectively . The difference between INCENT and LMW group in weight loss and BMI reduction were not statistically significant . Conclusion The current study suggests that INCENT and a minimal intervention alternative may be effective approaches to help decrease the overall obesity burden within worksites Background There was an increasing trend in the prevalence of obesity and its comorbidities over the past decades in Malaysia . Effective intervention for obesity remains limited . This study aim ed to compare the effectiveness of a group based lifestyle modification programme  amongst obese individuals with an existing dietary counseling programme . Methods We recruited one hundred and ninety four overweight and obese ( BMI > 27.5 kg/m2 ) employees from a local university . They were r and omly allocated to either Group Support Lifestyle Modification ( GSLiM ) (intervention)(n = 97 ) or dietary counseling (comparison)(n = 97 ) . The GSLIM activities included self monitoring , cognitive-behaviour sessions , exercise as well as dietary change advocacy , which were conducted through seminars and group sessions over 24 weeks . The comparison group was given dietary counselling once in 12 weeks . Both groups were followed up for additional 12 weeks to check for intervention effect sustenance . Anthropometric and biochemical parameters were measured at baseline , 12 , 24 and 36 weeks ; while dietary intake , physical activities , psychological measures and quality of life measured at baseline , 24 and 36 weeks . Data analysis was conducted using ANOVA repeated measures with intention to treat principle . Results The participants were predominantly women with mean ( st and ard deviation ) age of 40.5 ( 9.3 ) years . A total of 19.6 % of the participants in GSLiM achieved 6 % weight loss compared to 4.1 % in the comparison group ( Risk Ratio 4.75 ; 95 % CI : 1.68 , 13.45 ) . At 24 weeks , the retention rate was 83.5 % for GSLiM and 82.5 % for comparison group . GSLiM participants also achieved significant improvement in total weight self-efficacy score , negative emotions and physical discomfort subscales , MDPSS friend subscale and all domains in quality of life . Participants in the comparison group experienced reduction in negative self-thoughts . Conclusion The GSLiM programme proved to be more effective in achieving targeted weight loss , improving weight self-efficacy , friend social support , and quality of life compared to dietary counseling . Trial Registration Iranian Registry of Clinical Trials I RCT Background Weight management constitutes a substantial problem particularly among groups of low socio-economic status . Interventions at work places may be a solution , but high quality worksite interventions documenting prolonged weight loss are lacking . This paper presents results of an intervention aim ed to achieve a 12 months weight loss among overweight health care workers . Methods Ninety-eight overweight female health care workers were r and omized into an intervention or a reference group . The intervention consisted of diet , physical exercise and cognitive behavioral training during working hours 1 hour/week . The reference group was offered monthly oral presentations . Several anthropometric measures , blood pressure , cardiorespiratory fitness , maximal muscle strength , and musculoskeletal pain were measured before and after the 12-months intervention period . Data were analyzed by intention-to-treat analysis . Results The intervention group significantly reduced body weight by 6 kg ( p < 0.001 ) , BMI by 2.2 ( p < 0.001 ) and body fat percentage by 2.8 ( p < 0.001 ) . There were no statistical reductions in the control group , result ing in significant differences between the two groups over time . Conclusions The intervention generated substantial reductions in body weight , BMI and body fat percentage among overweight female health care workers over 12 months . The positive results support the workplace as an efficient arena for weight loss among overweight females . Trial registration NCT01015716 Introduction Working adults spend much time at the workplace , an ideal setting for wellness programs targeting weight loss and disease prevention . Few r and omized trials have evaluated the efficacy of worksite diabetes prevention programs . This study evaluated the efficacy of a worksite lifestyle intervention on metabolic and behavioral risk factors compared with usual care . Methods A pretest – posttest control group design with 3-month follow-up was used . Participants with prediabetes were recruited from a university worksite and r and omized to receive a 16-week lifestyle intervention ( n = 35 ) or usual care ( n = 34 ) . Participants were evaluated at baseline , postintervention , and 3-month follow-up . Dietary intake was measured by a food frequency question naire and level of physical activity by accelerometers . Repeated measures analysis of variance compared the change in outcomes between and within groups . Results Mean ( st and ard error [ SE ] ) weight loss was greater in the intervention ( −5.5 % [ 0.6 % ] ) than in the control ( −0.4 % [ 0.5 % ] ) group ( P < .001 ) postintervention and was sustained at 3-month follow-up ( P < .001 ) . Mean ( SE ) reductions in fasting glucose were greater in the intervention ( −8.6 [ 1.6 ] mg/dL ) than in the control ( −3.7 [ 1.6 ] mg/dL ) group ( P = .02 ) postintervention ; both groups had significant glucose reductions at 3-month follow-up ( P < .001 ) . In the intervention group , the intake of total energy and the percentage of energy from all fats , saturated fats , and trans fats decreased , and the intake of dietary fiber increased ( all P < .01 ) postintervention . Conclusion The worksite intervention improved metabolic and behavioral risk factors among employees with prediabetes . The long-term impact on diabetes prevention and program sustainability warrant further investigation OBJECTIVES To improve nutrition and physical activity of county employees and promote weight loss . DESIGN R and om assignment to begin the program when first offered or after 3 months ( " wait control " group ) . SETTING Worksite . PARTICIPANTS Onondaga County employees ( n = 45 ) at risk for diabetes ( n = 35 ) or with diabetes ( n = 10 ) . Mean ( ±SD ) age = 51.2 ( ± 8.0 ) years and body mass index ( BMI ) = 37.3 ± ( 6.8 kg/m ) . INTERVENTION Twelve weekly healthy lifestyle sessions based on the Diabetes Prevention Program curriculum , followed by monthly sessions for up to 12 months . OUTCOMES Medical : Weight , BMI , waist circumference , blood pressure , fasting glucose , lipid , and hemoglobin A1c levels . Psychosocial/behavioral : Health-related quality of life Short Form-12 , Impact of Weight on Quality of Life Scale ) , physical activity ( International Physical Activity Question naire ) , eating behavior ( 3-Factor Eating Question naire , National Cancer Institute Fat Screener ) , job satisfaction . RESULTS The intervention group lost significant weight compared to the wait control group over the first 3 months ( mean [ 95 % CI ] , -2.23 kg [ -3.5 to 0.97 ] ) vs [ + 0.73 kg ( + 0.17 to + 1.28 ) ] , with a decrease in BMI ( P < .001 ) and waist circumference ( P = .004 ) , an increase in physical activity ( International Physical Activity Question naire , P = .011 ) and lower dietary fat intake ( P = .018 ) . Over 12 months , 22.5 % ( 9/40 ) lost more than 5 % body weight and 12.5 % ( 5/40 ) lost more than 7 % body weight . After the first 3 months , there was gradual partial weight regain but reduction in waist circumference was maintained . The intervention group demonstrated significant improvement in Impact of Weight on Quality of Life Scale ( P < .001 ) , 3-Factor Eating ( cognitive restraint P < .001 , uncontrolled eating P = .003 , and emotional eating P = .001 ) , International Physical Activity Question naire ( P = .011 ) , and Short Form-12 Physical Component Summary ( P = .048 ) . No improvements were observed in blood pressure , lipid , hemoglobin A1c , or glucose levels . Job satisfaction was inversely related to BMI at baseline ( P = .001 ) with a trend for improvement with the modest weight loss . CONCLUSIONS A worksite intervention program can help government employees adopt healthier lifestyles and achieve modest weight loss Purpose . We assessed the effectiveness of a worksite management intervention ( the 3W program ) for overweight and obese hotel employees . Design . The program was tested in a 2-year cluster-r and omized trial involving 30 hotels that employed nearly 12,000 individuals . Setting . All participating hotels were on Oahu , Hawaii . The intervention was implemented within hotel worksites . Subjects . Participants were included in the analysis if they had an initial body mass index ( BMI ) ≥ 25 , were assessed at least twice , were not missing other data needed for the analysis , and did not switch to employment at a hotel in a different experimental condition . Of the 6519 employees we assessed , data from 1207 individuals ( intervention : 598 ; control : 610 ) met these criteria and contributed to the analysis . Intervention . The intervention had two components : ( 1 ) group meetings and ( 2 ) a workplace environment intervention .  Measures . Weight and waist to height ratio ( WHtR ) were measured at three annual assessment s. Analysis . The effect of the intervention on change in BMI and WHtR was estimated in hierarchical mixed regression models using full maximum likelihood to estimate model parameters . Results . The effects on change in BMI and WHtR were in the expected direction but were not statistically significant . Conclusion . The 3W program was not effective . The low intensity of the intervention may have contributed to its ineffectiveness OBJECTIVE To evaluate the feasibility and efficacy of a workplace-based weight loss program ( Workplace POWER-WP ) for male shift workers . METHOD A prospect i ve , two-armed r and omized controlled trial of 110 overweight/obese ( BMI 25 - 40 ) ( mean [ SD ] age = 44.4 [ 8.6 ] years ; BMI = 30.5 [ 3.6 ] ) male employees at Tomago Aluminium aged 18 - 65 . In October ( 2009 ) men were r and omized to either ( i ) WP program ( n=65 ) or ( ii ) a 14-week wait-list control group ( n=45 ) . The 3-month program involved one information session , program booklets , group-based financial incentives and an online component . Men were assessed at baseline and at 14-week follow-up for weight ( primary outcome ) , waist circumference , BMI , blood pressure , resting heart rate , self-reported physical activity and dietary variables , and physical activity and dietary cognitions . RESULTS Intention-to-treat analysis using linear mixed models revealed significant between group differences for weight loss after 14 weeks ( P < .001 , Cohen 's d = 0.34 ) . Significant intervention effects were also found for waist circumference ( P < .001 , d = 0.63 ) , BMI ( P < .001 , d = 0.41 ) , systolic blood pressure ( P = .02 , d = 0.48 ) , resting heart rate ( P < .001 , d = 0.81 ) , physical activity ( P = .03 , d = 0.77 ) , sweetened beverages ( P < .02 , d = 0.5 - 0.6 ) and physical activity-related cognitions ( P < .02 , d=0.6 ) . CONCLUSION The WP program was feasible and efficacious and result ed in significant weight loss and improved health-related outcomes and behaviours in overweight male shift workers BACKGROUND The long-term effectiveness of multicomponent worksite health promotion programs targeting cardiovascular disease risk factors remains unclear in Japan . This study was conducted to evaluate the effectiveness of such a health promotion program consisting of a main program provided over 4 days and a follow-up program provided over 1 year . METHODS The subjects of this r and omized controlled trial were male employees working for a building maintenance company in Japan . The intervention group ( n = 152 ) and the control group ( n = 150 ) consisted of employees having abnormal findings in at least one of the following items at baseline health examination : body mass index ( BMI ) , systolic ( SBP )  or  diastolic blood pressure , total cholesterol , HDL cholesterol , triglycerides , and fasting blood glucose . Evaluation was conducted at 18 months after the main program . RESULTS BMI , SBP , total cholesterol , and triglycerides improved significantly in the intervention group compared with the control group ( P < 0.05 ) . When comparisons were limited to those who showed abnormality at baseline , BMI , total cholesterol , and triglycerides improved significantly in the intervention group ( P < 0.05 ) . CONCLUSIONS The multicomponent health promotion program provided to employees was shown to be effective in improving obesity , high blood pressure , and hyperlipidemia when evaluated 18 months after the main intervention program OBJECTIVES We used a participatory process to develop an obesity intervention appropriate for elementary school personnel . METHODS A r and omized controlled trial included 16 school worksites ( 8 intervention , 8 control ) .  Intervention schools formed committees to develop and implement health promotion activities for employees .  Anthropometric and self-report data were collected at baseline and postintervention ( 2 years later ) . The primary outcome measures were body mass index ( BMI ) , waist-hip ratio , physical activity , and fruit and vegetable consumption . RESULTS After adjustment for age , ethnicity , and job classification , employees in intervention schools reduced their BMI by an average of 0.04 kg/m2 , and those in control schools increased their BMI by an average of 0.37 kg/m2 . Comparisons for waist-hip ratio , weekly physical activity minutes , and fruit and vegetable consumption were not significant . CONCLUSIONS The participatory process appeared to be an effective means for stimulating change . The intervention may have slowed and perhaps reversed the tendency of adults to gain weight progressively with age Purpose : To evaluate the effectiveness of an individually tailored intervention for improvement in lifestyle behavior , health indicators , and prevention and reduction of overweight among construction workers . Design : R and omized controlled trial . Setting : Various blue-collar departments of a large construction company in the Netherl and s. Participants : Blue-collar workers r and omized to an intervention ( n = 162 ) or a control group ( n = 152 ) . Intervention : The intervention group received individual coaching sessions , tailored information , and material s to improve lifestyle behavior during a 6-month period , and the control group received usual care . Measures : Body weight , body mass index ( BMI ) , waist circumference , physical activity ( PA ) levels , dietary behavior , blood pressure , and blood cholesterol were assessed . Analysis : Effectiveness of the intervention on outcome measures at 6- and 12-month follow-up was assessed by using linear and logistic regression models adjusting for baseline levels . Results : After 6 months , a statistically significant intervention effect was found on body weight ( B = −1.06 , P = .010 ) , BMI ( B = −0.32 , P = .010 ) , and waist circumference ( B = −1.38 , P = .032 ) . At 6 months , the percentage of those meeting public health guidelines for PA increased significantly in the intervention group compared to the control group ( B = 2.06 , P = .032 ) , and for sugar-sweetened beverages , an intervention effect was found at 6 months as well ( B = −2.82 , P = .003 ) . At 12 months , for weight-related outcomes , these differences were slightly smaller and no longer statistically significant . The intervention was not effective on the total amount of moderate to vigorous PA and other dietary and health outcomes . Conclusion : Intervention participants showed positive changes in vigorous PA and intake of sugar-sweetened beverages compared to controls , as well as effects on weight-related outcomes at 6 months . Long-term effects were still promising but not statistically significant Objective : To determine whether an evidence -based , behavioral lifestyle intervention program delivered at a worksite setting is effective in improving type 2 diabetes and cardiovascular disease risk factors .  Methods : A r and omized 6-month delayed control design was utilized , with two thirds of the participants assigned to begin intervention immediately , and one third beginning 6 months later . The year-long program ( weekly for 3 months transitioning to monthly ) focused on weight loss and increasing physical activity . Results : The immediate intervention group had greater mean weight loss ( −10.4 lb , 5.1 % , vs −2.3 lb , 1 % ; P = 0.0001 ) than the delayed control group at 6 months and relatively greater improvements in activity , HbA1c , and other risk factors . The delayed group experienced similar improvements after completing the intervention program . Conclusions : A worksite behavioral lifestyle intervention is feasible and effective in significantly improving risk factors for type 2 diabetes and cardiovascular disease Overweight and physical inactivity are risk factors for increased disease burden and health care expenditure . Well- design ed studies are still needed to determine the treatment efficacy of worksite interventions targeting such risk factors . This r and omized controlled trial was conducted at one of Australia 's casinos in 2002 - 2003 , to investigate the effects of a comprehensive exercise and lifestyle intervention on physical fitness . Only 6.4 % of the workforce expressed interest in being study participants . Seventy-three employees ( aged 32 + /- 8 years , 51 % overweight/obese , 73 % shift workers and 52 % women ) were recruited and r and omized to treatment or wait-list control groups for 24 weeks , 44 of whom completed the intervention . Components of the intervention include supervised moderate-to-high intensity exercise including combined aerobic ( at least 20 min duration 3 days/week ) and weight-training ( for an estimated 30 min completed 2 - 3 days/week ) , and dietary/health education ( delivered via group seminars , one-on-one counselling and literature through the provision of a worksite manual ) . ANCOVA , by intention-to-treat and of study completers , found significant between-group differences in the mean waist circumference and predicted maximal oxygen uptake ( VO2max ) , favouring the intervention , but effects were concentrated in one subject . For study completers , between-group differences in the mean waist circumference ( 82.3 + /- 9.2 versus 90.5 + /- 17.8 cm , p = 0.01 ) and predicted VO2max ( 47 versus 41 ml/kg/min , p < 0.001 ) remained significant without the outlier , favouring the intervention . Higher intervention compliance predicted greater improvements in physical fitness . No significant effects on body mass or body mass index were found . This worksite intervention significantly improved waist circumference and aerobic fitness in healthy but sedentary employees , most of whom were shift workers .  Worksite interventions have the potential to counter the increasing burden of overweight and obesity , particularly visceral adiposity , as well as physical inactivity ; however , substantial barriers to adoption/adherence need to be overcome for greater feasibility and impact on employee physical health OBJECTIVE The results of an 18-month worksite intervention to prevent obesity among metropolitan transit workers are reported . METHODS Four garages in a major metropolitan area were r and omized to intervention or control groups . Data were collected during the fall of 2005 prior to the start of the intervention and during the fall of 2007 , after the intervention ended . Intervention program components at the garage included enhancement of the physical activity facilities , increased availability of and lower prices on healthy vending machine choices , and group behavioral programs . Mixed model estimates from cross-sectional and cohort sample s were pooled with weights inverse to the variance of their respective estimates of the intervention effects . RESULTS Measurement  participation rates were 78 % at baseline and 74 % at follow-up . The intervention effect on garage mean BMI change was not significant ( -0.14 kg/m(2 ) ) . Energy intake decreased significantly , and fruit and vegetable intake increased significantly in intervention garages compared to control garages . Physical activity change was not significant . CONCLUSION Worksite environmental interventions for nutrition and physical activity behavior change may have limited impact on BMI among transit workers who spend most of their workday outside the worksite Individuals who are physically fit or engage in regular physical activity have a lower incidence of cardiovascular disease and risk of mortality . We conducted a large-scale controlled trial of interventions to decrease cardiovascular risk factors , during which we assessed the effect of a workplace-based intervention program , which was part of a population strategy for promoting long-term increases in physical activity , on the blood lipid profiles  of participating employees . Data were collected from 2929 participants and this report presents the results of a survey conducted in five factories for the intervention group and five factories for the control group at baseline and year 5 . The absolute/proportional changes in HDL-cholesterol were 2.7 mg/dL ( 4.8 % ) in the intervention group and -0.6 mg/dL ( -1.0 % ) in the control group . The differences between the two groups in the change in serum levels of HDL-cholesterol were highly significant ( p<0.001 ) in each analysis of covariance , in which the number of cigarettes smoked was included or excluded . In the intervention group , the  daily walking time  increased significantly ( p<0.001 ) when compared between baseline and year 5 , whereas no significant difference was observed in daily walking time in the control group over the identical period . Our results show that an intervention program promoting physical activity raises serum HDL-cholesterol levels of middle-aged employees . Increased awareness of the benefits of physical activity , using environmental rearrangement and health promotion campaigns , which especially target walking , may have contributed to a beneficial change in serum HDL-cholesterol levels in the participants
target: Reduction in blood pressure , lipids and blood glucose was not statistically significant .
  Conclusions Workplace interventions  significantly reduced body weight , BMI and waist circumference .
  Non-significant results for biochemical markers could be due to them being secondary outcomes in most studies .
background: Background Adults in urban areas spend almost 77 % of their waking time being inactive at workplaces , which leaves little time for physical activity .
  The aim of this systematic review and meta- analysis was to synthesize evidence for the effect of workplace physical activity interventions on the cardio-metabolic health markers ( body weight , waist circumference , body mass index ( BMI ) , blood pressure , lipids and blood glucose ) among working adults .
