The eat well be active Community Programs (ewba) aimed to prevent obesity among children aged 0–18 years in two Australian communities from 2006 to 2010.
ewba was a multi-strategy intervention in children’s settings. The evaluation was quasi-experimental, including a before and after survey with intervention (INT) and non-randomised comparison (COMP) communities. Outcome measures included BMI-z score (zBMI) and overweight/obesity prevalence in children aged 4–5 years; and zBMI, waist circumference (WC) z-score and overweight/obesity prevalence in children aged10–12 years.
After 3 years, among the 4–5 years old, mean zBMI was significantly lower in both INT (−0.20, p < 0.05) and COMP (−0.15, p < 0.05), however, changes were not significantly different between INT and COMP. There was a larger reduction in overweight/obesity prevalence in INT (−6.3 %) compared to COMP (−3.7 %) (p < 0.05, χ2 test). In the 10–12 years old, mean zBMI did not change significantly in INT or COMP. There was a significant reduction in WC z-score in INT (−0.17, p < 0.05) but not in COMP (−0.10, p = NS), although not significantly different between INT and COMP (p = 0.092).
These findings suggest that the ewba community intervention had a moderate impact, showing modest improvements in weight status at 3-year follow-up.
