joint monitoring programme for water supply and sanitation ( jmp ) , defines open defecation as ' ' unimproved '' . nearly 60 per cent of the people in the world who defecate in the open belong to india . unsanitary disposal of human excreta , along with unsafe drinking water and poor hygiene conditions , is a leading cause of morbidity and mortality in low - income countries . much of this disease burden consists of diarrheal disease , a leading cause of death in young children . in addition , inadequate sanitation is implicated in schistosomiasis , helminth infections , enteric fevers and trachoma . lack of access to sanitation also has significant non - health consequences , particularly for women and girls , including lack of security and privacy , decreased school attendance and basic human dignity . swachh bharat mission was launched by prime minister of india to accelerate the efforts for achieving universal sanitation coverage and to put emphasis on sanitation . thus , this study focuses on sanitary latrine usage , open air defecation and its attendant medical problems as its objectives and intends to positively reform the awareness level and practices of the rural population in kuthambakkam village in tamil nadu . the present study was a community based cross sectional study which was conducted among the rural population in kuthambakkam village , tamil nadu . kuthambakkam village is a rural field practice area of department of community medicine , saveetha medical college and hospital , thandalam . the households were serially numbered and of these , a sample of 275 households were selected for the study using simple random sampling technique by lottery method . one member from each household , preferably the head of the family ( if not available , any elder person in the family ) , was interviewed personally . a structured questionnaire was used to collect information regarding the background characteristics , their knowledge , attitude and practices about sanitary latrine usage . the purpose of the study was explained to the participants and an informed consent was obtained . data entry and analysis was done using the statistical package for social sciences ( spss ) version 16 software . descriptive statistics were calculated for background variables , prevalence of sanitary latrine usage and open air defecation . association between factors responsible for open air defecation was found by using chi square test . of the 275 participants included in the study , 223(81.1% ) were male and 52(18.9% ) were female . majority were hindus ( 98.2% ) , while 1.1% were christians & the rest were muslims . among the study participants , most of them had a low standard of living 196 ( 71.3% ) , while 71 ( 25.8% ) had medium and 8 ( 2.9% ) participants had higher standard of living . among interviewed participants it was found that majority of the study participants 172 ( 62.5% ) had sanitary latrines in their houses and all their family members were using it . public tap ( 161 of 172 ) was the most common source of water supply for the toilets followed by well water . the usage of community toilets was 4.3%.among a total of 103 participants who did not have a sanitary latrine at their homes , 91practiced open air defecation while the rest used community toilets . the prevalence of open air defecation in the present study was found to be 33.1% ( 91 of 275 ) [ table 1 ] . lack of money , lack of space , lack of interest and staying in rented houses were some of the reasons given for non - construction of toilets by the participants [ table 2 ] . only 3.3% had confirmed that some health advisor came over to their houses to promote and construct toilets within the premises . media was an important source of information about sanitary latrines among all the study participants . however , a majority 87.2% did not know that diseases can be spread due to the practice of open air defecation [ table 3 ] . reasons for non construction of sanitary latrines at home awareness about open air defecation in univariate analysis , significant association was found between lower standard of living and open air defecation practice ( p = 0.0016 ) [ table 4 ] . this cross sectional study was carried out in a rural population at kuthambakkam village , thandalam , tamil nadu , to estimate the prevalence of open air defecation and to assess the association between open air defecation and social factors . in spite of presence of community latrines , results were observed by another study conducted in bangladesh , where open air defecation was practiced by 42% to 79% of the total population . a study done in maharashtra by anu bhardwaj , et al . showed that 67% practiced open air defecation . the finding of the current study was not comparable with the finding of the study done by anu bhardwaj . the proportion of the world population that practices open defecation declined by almost one third from 25% in 1990 to 17% in 2008.a decline in open defecation rates was recorded in all regions . in sub - saharan africa , open defecation rates fell by 25 per cent . in absolute numbers , the population practicing open defecation increased from 188 million in 1990 to 224 million in 2008 . in southern asia , home to 64% of the world population that defecate in the open , the practice decreased the most  from 66% in 1990 to 44% in 2008 ( who / unicef jmp for water supply and sanitation , 2010 ) . in a study conducted by j. geetha in tiruchirappalli , tamil nadu , the prevalence of open air defecation was 90% . ananta prasad ( 2013 ) asserts that more than 2.5 billion people lack adequate sanitation worldwide , especially in developing countries like india . of these , 1 billion people defecate in the open . in the least developed countries , one in four people defecate in the open largely as a result of poverty and inability to build separate toilets and the issues of space , land . in the present study , significant association was found between lower socioeconomic status and open air defecation practice ( p = 0.0016 ) . ashish bijaykrishna banerjee et al . conducted a study to understand household behavior and attitude towards open air defecation by the residents and motivate public toilet / private toilet among 236 households of nandivargam village of kurnool district . raising the standard of living plays an important role in increasing the usage of sanitary latrines . awareness about the diseases transmitted by open air defecation is found to be very poor in this study . however , in a study conducted by j. geetha only a few out of the sample population ( 14.5% ) were not aware of the harmful effects of open air defecation . the hygiene part of sanitation is keeping the toilets clean and tidy , which in turn protects the users from illness and disease . lack of interest , money and space are the important reasons for non - construction of house hold latrines . awareness regarding the ill effects of open air defecation is also poor . improved sanitation is important not only for human health , but also for social and economic development of the country . it intends to positively reform the awareness level and practices on open defecation of rural households . planning and conducting information education communication activities on this important issue on a regular basis is extremely necessary .
