Effects of the Quest to Lava Mountain Computer Game on Dietary and Physical Activity Behaviors of Elementary School Children : A Pilot Group-Randomized Controlled Trial . BACKGROUND Computer-based educational games present an opportunity for health education in school ; however , their feasibility in school settings and effectiveness in changing behavior are poorly understood . OBJECTIVE To evaluate the feasibility , acceptability , and effects of the Quest to Lava Mountain ( QTLM ) computer game on dietary behaviors , physical activity behaviors , and psychosocial factors among ethnically diverse children in Texas . DESIGN Quasi-experimental group-randomized controlled trial conducted during the 2012-2013 school year . PARTICIPANTS/SETTING A total of 107 children in fourth and fifth grade consented . There was an attrition rate of 8.8 % with a final sample size of 44 children in three intervention schools , and a sample of 50 children in three comparison schools . Dietary intake was measured using two random 24-hour recalls , whereas child self-report surveys measured diet , physical activity , and psychosocial factors before and after the intervention . Process data on QTLM usability and back-end server data on QTLM exposure and progress achieved were collected . INTERVENTION QTLM was implemented as part of the in-school or afterschool program . Recommended game exposure duration was 90 min/wk for 6 weeks . STATISTICAL ANALYSIS Analysis of covariance or logistic regression models evaluated effects of QTLM on diet , physical activity , and psychosocial factors . Post hoc exploratory analysis examined the changes before and after the intervention in outcome variables among children in the intervention group . Significance was set at P < 0.05 . RESULTS Children played an average of 274±110 minutes ( approximately 4.6 hours ) of QTLM during the 6 weeks ( 51 % of recommended dosage ) . Compared with the comparison group , children in the intervention group reported decreased sugar consumption ( P=0.021 ) and higher nutrition/physical activity attitudes ( P=0.041 ) pre- to postintervention . There were no significant effects of QTLM on physical activity . However , post hoc analysis showed that higher QTLM exposure and gaming progress was associated with increased frequency of physical activity ( P < 0.05 ) . CONCLUSIONS QTLM has some promising acceptability and initial effects on diet and physical activity behaviors among children in elementary school .
