Background Early childhood is a crucial time to foster healthy eating and physical activity (PA) habits, which are critical for optimal child health, growth and development. Child care facilities are important settings to promote healthy eating and PA and prevent childhood obesity; however, almost all prior intervention studies have focused on child care centers and not family child care homes (FCCH), which care for over 1.6 million U.S. children. Methods This paper describes Healthy Start/Comienzos Sanos, a cluster-randomized trial evaluating the efficacy of a multicomponent intervention to improve nutrition and PA environments in English and Spanish-speaking FCCH. Eligible child care providers complete baseline surveys and receive a two-day FCCH observation of the home environment and provider practices. Parent-consented 2–5 year-old children are measured (height, weight, waist circumference), wear accelerometers and have their dietary intake observed during child care using validated protocols. FCCH providers are then randomly assigned to receive an 8-month intervention including written materials tailored to the FCCH providers’ need and interest, videos, peer support coaching using brief motivational interviewing, and periodic group meetings focused on either nutrition and PA (Intervention) or reading readiness (Comparison). Intervention materials focus on evidence-based nutrition and physical activity best practices. The initial measures (surveys, two-day observation of the FCCH and provider practices, child diet observation, physical measures, and accelerometer) are assessed again 8 and 12 months after the intervention starts. Primary outcomes are children’s diet quality (Healthy Eating Index), time in moderate and vigorous PA and sedentary PA during child care. Secondary outcomes include FCCH provider practices and foods served, and PA environments and practices. Possible mediators (provider attitudes, self-efficacy, barriers and facilitators) are also being explored. Process evaluation measures to assess reach, fidelity and dose, and their relationship with dietary and PA outcomes are included. Discussion Healthy Start/Comienzos Sanos fills an important gap in the field of childhood obesity prevention by rigorously evaluating an innovative multicomponent intervention to improve the nutrition and physical activity environments of FCCH.

Background: Child care settings play an important role in shaping children's eating behaviors; yet few studies have included family child care homes (FCCHs). We examined provider-reported nutrition-related practices in FCCHs and observed adherence to nutrition guidelines from the Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC), exploring differences by provider ethnicity. Methods: We assessed baseline data from a cluster-randomized trial, including surveys with FCCH providers and observational data collected at the FCCH. We examined provider-reported nutrition-related practices and if providers met NAP SACC guidelines using observational data. Differences by ethnicity were assessed using chi-square and multivariate log-linear analysis adjusting for education. Results: Providers completed a telephone survey (n = 166, 100% female and 72% Hispanic) and participated in 2 full-day observations (n = 119). Many providers reported engaging in positive nutrition-related practices. Significant differences by ethnicity included the following: Hispanic providers less likely to report feeding practices that were responsive to children's self-regulation, but also less likely to report eating and drinking unhealthy foods/beverages in front of children and having screens on during meals and more likely to report seeking nutrition trainings. Using observational data, only 10 of 26 NAP SACC practices were met by >60% of providers. Few ethnic differences in meeting guidelines were found (7 of 26 practices). Conclusions: While providers engage in some positive nutrition practices, improvement is needed to ensure that all providers actually meet evidence-based guidelines. Ethnic differences in certain practices underscore the need for culturally relevant trainings. Trial registration number: NCT02452645.

BackgroundThe speeding increase and the high prevalence of childhood obesity is a serious problem for Public Health. Community Based Interventions has been developed to combat against the childhood obesity epidemic. However little is known on the efficacy of these programs. Therefore, there is an urgent need to determine the effect of community based intervention on changes in lifestyle and surrogate measures of adiposity.Methods/designParallel intervention study including two thousand 2249 children aged 8 to 10 years ( 4th and 5th grade of elementary school) from 4 Spanish towns. The THAO-Child Health Program, a community based intervention, were implemented in 2 towns. Body weight, height, and waist circumferences were measured. Children recorded their dietary intake on a computer-based 24h recall. All children also completed validated computer based questionnaires to estimate physical activity, diet quality, eating behaviors, and quality of life and sleep. Additionally, parental diet quality and physical activity were assessed by validated questionnaires.DiscussionThis study will provide insight in the efficacy of the THAO-Child Health Program to promote a healthy lifestyle. Additionally it will evaluate if lifestyle changes are accompanied by favorable weight management.Trial registrationTrial Registration Number ISRCTN68403446
