An Implementation Approach Comparison of a Child Care Center-Based Obesity Prevention Program.

OBJECTIVE: To compare the effectiveness of the Healthy Caregivers-Healthy Children (HC2) phase 1 (2011-2014) and 2 (2015-2018) child care center (CCC)-based obesity prevention intervention(s) on child dietary practices and body mass index percentile (PBMI) outcomes over 2 years. Phase 1 was implemented via a university-based research team, and phase 2 was delivered via a train-the-trainers approach (university-based research team trains preschool-based coaches, who in turn train CCC teachers to implement and disseminate HC2). METHODS: Phase 1 and 2 were both cluster randomized controlled trials of the HC2 obesity prevention intervention. Phase 1 was composed of 1224 children in 28 CCCs (12 intervention and 16 control). Phase 2 was composed of 825 children in 24 CCCs (12 intervention and 12 control). Both phases included CCCs serving low-resource, predominantly ethnic minority families. RESULTS: The mean rate of weekly fruit consumption significantly increased (ß = 0.16, p = 0.001) in phase 1, whereas vegetable intake significantly increased (ß = 0.16, p = 0.002) in phase 2 intervention CCCs. Fried (ß = -0.36, p < 0.001), fast (ß = -0.16, p = 0.001), and other unhealthy food (ß = -0.57, p < 0.001) consumption significantly decreased in phase 1 only. The mean rate of snack food consumption significantly decreased in phase 2 (ß = -0.97, p < 0.001). Mean child PBMI remained in the healthy range over 2 years for all groups in both study phases. CONCLUSION: A university-based research team implementation and dissemination approach seemed to be more effective than a train-the-trainers implementation method in improving dietary intake patterns. This finding suggests that CCCs may need robust educational support beyond their existing internal resources for long-term positive dietary intake pattern changes.

Healthy caregivers-healthy children (HC2) phase 2: Integrating culturally sensitive childhood obesity prevention strategies into childcare center policies.

OBJECTIVE: Despite the high prevalence of obesity among preschool-aged children, most states lack childcare center (CCC) nutrition and physical activity policies. The Healthy Caregivers, Healthy Children (HC) Phase 2 project is examining the relationship between the CCC nutrition and physical activity environment and child dietary intake/physical activity patterns and body mass index (BMI). PARTICIPANTS: A total of 24 "Quality Counts" (Miami Dade County, Florida's Quality Rating Improvement System [QRIS)]) CCCs serving low resource families with ≥50 2-to-5year olds attending have been randomized to either intervention (n=12) or control (n=12). INTERVENTION: The HC2 intervention arm CCCs receive implementation of a daily curricula for (1) teachers/parents; (2) children; (3) snack, beverage, physical activity, and screen time policies; and (4) technical assistance with menu modifications. Control arm schools receive an attention control safety curriculum. HC2 is delivered once a month in year 1, quarterly in year 2 and will be disseminated throughout the Quality Counts network in year 3. MAIN OUTCOME MEASURES: Primary outcome measures include the Environment and Policy Assessment and Observation tool (EPAO), standardized dietary intake and physical activity patterns surveys, and child BMI. The 'Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM)' framework will guide the interpretation of outcome measures. CONCLUSIONS: CCCs are in need of evidence-based standardized nutrition and physical activity policies. The intersection of RE-AIM and early childhood obesity prevention in the childcare setting could generate robust and new information to the field about potential barriers, facilitators, adoption, and sustainability in this setting.
