Health Education family-based intervention online intervention overweight prevention process evaluation healthy lifestyles mother-child dyad Background: The family and home environment is an influential psychosocial antecedent of pediatric obesity. Completion of conventional family-and-home-based (FHB) pediatric obesity interventions is challenging for parents, often requiring them to attend multiple on-site educational sessions. Under such constraints, an Internet-based intervention has the potential to modify determinants of pediatric obesity while making judicious use of parents’ time. Objectives: The purpose of this study was to evaluate the efficacy of The Enabling Mothers to Prevent Pediatric Obesity Through Web-Based Education and Reciprocal Determinism (EMPOWER) intervention; a novel, social cognitive theory (SCT), Web-based, maternal-centered program for prevention of pediatric obesity. The specific aims of this study addressed four salient barriers confronting the advancement of FHB pediatric obesity interventions: (1) efficacy of theory-based FHB interventions; (2) deficit in theoretical construct measurement; (3) high attrition rates; and (4) absence of process evaluation. In addressing these barriers, a comparison of the effects of a theory-based (EMPOWER) intervention against a knowledge-based (Healthy Lifestyles) intervention was conducted. Study dependent variables included four protective child behaviors (physical activity, fruit and vegetable consumption, sugar-free beverage consumption, and screen time) and five maternal-mediated constructs of SCT (environment, emotional coping, expectations, self-control, and self-efficacy). Methods: The trial targeted mothers with children in the age range of 4 to 6 years. Intervention measurement occurred through employment of a psychometrically validated instrument. Six layers of process evaluation transpired concurrently with each module. An intention-to-treat, repeated measures one-between, one-within subjects design with three levels was employed to collect study variable data at baseline (week 0), posttest (week 4), and follow-up (week 8). At each interval, summated scores for the SCT constructs and measures of the four protective child behaviors were collected. Results: A total of 57 participants were recruited. Process evaluation found both programs were administered as planned. Experimental and control groups were equivalent at baseline. Significant main effects were identified for child physical activity, sugar-free beverage consumption, and screen time, indicating that both groups improved in these behaviors. A significant group-by-time interaction was detected for child fruit and vegetable consumption as well as the SCT construct of environment. Fruit and vegetable consumption increased by 1.613 cups (95% CI [0.698, 2.529]) in the experimental group, relative to the control group. Gain score analysis found changes in environment accounted for 31.4% of the change in child fruit and vegetable intake. Conclusions: Child physical activity, sugar-free beverage consumption, and screen time improved in both groups over the course of the trial. However, only the theory-based intervention was efficacious in increasing child fruit and vegetable intake. Seasonality may have been partially responsible for the physical activity and screen time main effects. High construct scores at baseline may partially explain improvement in sugar-free beverage consumption. The EMPOWER program appeared robust for inducing change in the FHB environment leading to an increase in child fruit and vegetable consumption (Cohen’s <i>f</i> = 0.160). Mothers assume an important role in mediating change in antecedents of pediatric obesity and should be a central component for interventions targeting the family and home milieu. 2013-09-12 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1377865224 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1377865224 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
