BACKGROUND: In order to better target prevention initiatives for the obesity epidemic in Canada, policy-makers, in addition to information about risk factors, require an understanding of the preventive potential which is best provided by the risk factor's population attributable risk fraction (PARF). OBJECTIVE: To estimate the PARF for childhood overweight risk factors as identified by a population-based study of elementary schoolchildren in Nova Scotia. METHODS: Population-based survey data of Grade 5 students who participated in the 2003 Children's Lifestyle and School Performance Study in Nova Scotia, Canada, were linked to a provincial perinatal registry. PARFs were calculated from a parsimonious multilevel logistic regression model. RESULTS: Physical activity, sedentary activity, maternal smoking during pregnancy, and maternal pre-pregnancy weight were considered potentially preventable. Sedentary activity (as estimated from time spent viewing TV, computers and video games or "screen time") and maternal pre-pregnancy weight appeared to offer the greatest potential for prevention. In total, approximately 40% of-overweight in childhood could potentially be prevented. CONCLUSION: Excess screen time and maternal pre-pregnancy weight offer the greatest potential for prevention of childhood overweight at 11 years of age.
