Participation in structured programming may prevent unhealthy weight gain during the summer in school aged children from low income neighbourhoods: feasibility, fidelity and preliminary efficacy findings from the Camp NERF study
Abstract Objective Evaluate the feasibility, fidelity and preliminary efficacy of Camp NERF to prevent unhealthy weight gain and promote healthy behaviours in children during the summer. Design Camp NERF was an 8 week, multicomponent, theory based programme coupled with the US Department of Agriculture's Summer Food Service Program. Twelve eligible elementary school sites were randomized to one of three treatment groups: (i) Active Control (non nutrition, physical activity (PA) mental health) (ii) Standard Care (nutrition and PA) or (iii) Enhanced Care (nutrition and PA, plus cognitive behavioural techniques) programming. Efficacy was determined by assessing mean change by group in child outcomes using hierarchical linear regression models. Setting Low income, urban neighbourhoods in Columbus, OH, USA. Participants Economically disadvantaged, racial minority children of elementary school age (kindergarten 5th grade) Results Eighty seven child caregiver dyads consented; eighty one completed pre and post intervention assessments resulting in a 93*10 retention rate. Delivery of the intended lesson occurred 79 90 of the time. Of the children, 56*98 (n 49) were female; 89*53 (n 77) were Black. Overall mean change in BMI Z score from baseline to post intervention was 0*03 (se 0*05) change in BMI Z score did not differ significantly between treatment group. Change in nutrition, PA, mental health or psychosocial outcomes did not differ between groups. Conclusions Results from the current study demonstrate feasibility and fidelity, yet no intervention effect of Camp NERF. Instead, findings suggest that participation in structured programming of any type (health behaviour related or not) may prevent unhealthy summer weight gain. Additional studies are needed to confirm findings. Results have implications for child nutrition policy addressing the issue of summer health.
