The short and long-term impact of the healthy kids initiative on depressed mood in youth living with obesity

Abstract

PurposeThe purpose of this study is to determine the effect of a free, comprehensive program with social support on depressed mood in youth (aged 11–17 years) living with obesity in a prospective, longitudinal, community-based study. MethodsYouth living with obesity (BMI > 30), residing in three cities in Saskatchewan, Canada, were eligible to participate in a 12-week program designed to facilitate behavioural change with five physical activity sessions a week, one dietary session a week, and one group cognitive behavioural session per week offered by health care professionals. Baseline data were collected on depressed mood (Centre for Epidemiological Studies-Depression 12 or CES-D 12), health-related quality of life (SF-12), and self-esteem (NLSCY) at baseline, 12-weeks, and at 52-weeks ResultsOverall, 2598 youth started and 2292 (88.2 %) completed the 12-week program with 1703 (74.3 %) of participants presenting for 52-week follow-up. Depressed mood improved significantly over the course of the program: 79.2 % of participants had depressed mood at the start of the program and this decreased to 64.7 % at the end of 12-weeks; which was an overall relative reduction of 18.4 % (Cohen’s d = 0.94). The mean CES-D 12 score at one-year was significantly lower than the mean baseline score (17.90 compared to 21.11, p < .001). By depressed mood severity, 58.7 % of participants had severe depressed mood at baseline, which reduced to 31.6 % at 12 weeks, and 27.9 % at 52 weeks. Age and maternal occupation were initially significantly associated with depressed mood at 52-week follow-up (unadjusted). However, after binary logistic regression was used to determine the independent risk factors for having depressed mood at 52-week follow up, only older age (OR 1.88, 95 % CI 1.52–2.34, p < .001) was significant. ConclusionThe Healthy Kids Initiative lends more evidence that healthy behavioural interventions can have a positive impact on depressed mood among youth living with obesity.
