Evaluation of the Healthy Lifestyles Initiative for Improving Community Capacity for Childhood Obesity Prevention.

PURPOSE AND OBJECTIVES: Policy, systems, and environmental approaches are recommended for preventing childhood obesity. The objective of our study was to evaluate the Healthy Lifestyles Initiative, which aimed to strengthen community capacity for policy, systems, and environmental approaches to healthy eating and active living among children and families. INTERVENTION APPROACH: The Healthy Lifestyles Initiative was developed through a collaborative process and facilitated by community organizers at a local children's hospital. The initiative supported 218 partners from 170 community organizations through training, action planning, coalition support, one-on-one support, and the dissemination of materials and sharing of resources. EVALUATION METHODS: Eighty initiative partners completed a brief online survey on implementation strategies engaged in, materials used, and policy, systems, and environmental activities implemented. In accordance with frameworks for implementation science, we assessed associations among the constructs by using linear regression to identify whether and which of the implementation strategies were associated with materials used and implementation of policy, systems, and environmental activities targeted by the initiative. RESULTS: Each implementation strategy was engaged in by 30% to 35% of the 80 survey respondents. The most frequently used materials were educational handouts (76.3%) and posters (66.3%). The most frequently implemented activities were developing or continuing partnerships (57.5%) and reviewing organizational wellness policies (46.3%). Completing an action plan and the number of implementation strategies engaged in were positively associated with implementation of targeted activities (action plan, effect size = 0.82; number of strategies, effect size = 0.51) and materials use (action plan, effect size = 0.59; number of strategies, effect size = 0.52). Materials use was positively associated with implementation of targeted activities (effect size = 0.35). IMPLICATIONS FOR PUBLIC HEALTH: Community-capacity-building efforts can be effective in supporting community organizations to engage in policy, systems, and environmental activities for healthy eating and active living. Multiple implementation strategies are likely needed, particularly strategies that involve a high level of engagement, such as training community organizations and working with them on structured action plans.

Randomized controlled trial of REbeL: A peer education program to promote positive body image, healthy eating behavior, and empowerment in teens.

Short-term outcomes associated with participation in REbeL, a peer-led dissonance-based eating disorder prevention program for high school students, were evaluated. Seventy-one students across the three high schools were enrolled in the study (REbeL N = 48; Control N = 23) and were assessed on measures of eating attitudes and behaviors, body image, weight bias, self-esteem, empowerment, and mood at the beginning of the school year; 37 REbeL students and 20 control students completed assessments at the end of the school year. Mixed effects GLM compared groups on outcomes at the end of the academic year. When controlling for baseline scores, students in both REbeL schools, compared to control school students, demonstrated statistically significantly lower scores at post-test on the EDE-Q Global score, the EDE-Q Restraint, Eating Concern, Shape Concern and Weight Concern subscales, and the Body Checking Questionnaire (all ps < .05). This study provides preliminary empirical support for the REbeL program.

Characterization of a Regional Childhood Obesity Prevention and Treatment System.

This project characterized the system of childhood obesity-related programs and functions based on a socioecological framework within the Kansas City region to determine strengths, weaknesses, and leverage points for informing collective impact. A mixed-method approach was employed to identify and collect data ∼260 childhood obesity-related programs provided by 89 organizations. Findings indicated no major gaps in population or location served although few programs specifically focused on service to minority groups or neighborhoods. The region has many programs working within the system, yet the distribution of programs does not occur as expected throughout the dimensions of a standard socioecological model or community health system. In addition, several organizations perform certain leadership functions such as coordination, resource allocation, or monitoring, but none perform all, indicating the lack of a traditional "backbone" organization. These findings demonstrate how a region's childhood obesity prevention and treatment programs can be evaluated using a socioecological framework.

Implementation contextual factors related to youth advocacy for healthy eating and active living.

Healthy eating and active living are critical to youth health and development. Youth advocacy can improve health-related behaviors and environments by empowering youth to act as change agents in their community. This mixed-method study examined implementation contextual factors in relation to implementation success in high school youth advocacy projects targeting healthy eating and active living. Semi-structured interviews were conducted with key informants from each of the 21 participating youth groups. Interviews gathered information on implementation processes, barriers and facilitators, and Implementation Outcomes (Progress, Penetration, Health Impact, Sustainability, and an overall Implementation Success Composite). Interview responses were coded using the Consolidated Framework for Implementation Research (CFIR). Each identified construct was rated for its impact on implementation and ratings were tested for their association with the Implementation Outcomes. Cosmopolitanism (leveraging connections within the community; rated in 20 groups) and Internal Intervention Source (rated in 9 groups) showed consistent moderate/large associations with the Implementation Outcomes and Implementation Success Composite. Other moderate/large associations were outcome specific, with Student Group Leader Engagement, External Change Agents, and Student and Community Needs and Resources also being associated with the Implementation Success Composite. Implementation contextual factors, particularly community-connectedness, group functioning, and internal project idea development are important factors for implementing youth advocacy projects that will reach large numbers of people and be likely to lead to sustained health improvements. Implementation strategies that target these factors need to be developed and tested in partnership with community organizations to maximize success of youth advocacy efforts.
