Utter et al. (2011) evaluated the effectiveness of a youth-led school-based intervention aimed at reducing and preventing childhood obesity. Students were recruited from primary schools in South Auckland, New Zealand, who agreed to participate in the Living for Life study. The study consisted of 3881 children who were randomly assigned to the intervention or comparison group based on the school they attended. Six schools, four intervention schools and two observation schools, participated in the study. Parental consent and child assent were signed before participation in the intervention began. Baseline data were collected in 2005 for all students involved in the study. The intervention was conducted from 2006 to 2008. Follow-up measurements were performed at the end of 2008. All students in the intervention were between the ages of 9 and 13, but only students between the ages of 11 and 13 were used for the follow-up assessment due to prior exposure to the program. The intervention was designed and implemented by the School Student Health Council. An intervention coordinator was employed to oversee the Student Health Council to facilitate the program. The intervention provided students with the opportunity to create physical fitness activities, build quality relationships, and develop a strength training program for other students. All participants completed a nutrition and physical activity survey questionnaire before and after the intervention. Students had their BMI, BMI z-score, weight, and body fat percentage recorded for anthropometric measurements before and after the intervention. Participants were also assessed using the Pediatric Quality of Life Inventory. Using repeated measures ANOVA, the authors reported no statistically significant effects in anthropometric measures for students in the intervention and control groups (p>0.05 for both). There were no statistics
