RÉSUMÉ

OBJECTIVE: We examined the outcomes of the Child Health Initiative for Lifelong Eating and Exercise (CHILE) study, a group randomized controlled trial to design, implement, and test the efficacy of a trans-community intervention to prevent obesity in children enrolled in Head Start centers in rural American Indian and Hispanic communities in New Mexico. METHODS: CHILE was a 5-year evidence-based intervention that used a socioecological approach to improving dietary intake and increasing physical activity of 1898 children. The intervention included a classroom curriculum, teacher and food service training, family engagement, grocery store participation, and healthcare provider support. Height and weight measurements were obtained four times (fall of 2008, spring and fall of 2009, and spring of 2010), and body mass index (BMI) z-scores in the intervention and comparison groups were compared. RESULTS: At baseline, demographic characteristics in the comparison and intervention groups were similar, and 33% of all the children assessed were obese or overweight. At the end of the intervention, there was no significant difference between the two groups in BMI z-scores. CONCLUSIONS: Obesity prevention research among Hispanic and AI preschool children in rural communities is challenging and complex. Although the CHILE intervention was implemented successfully, changes in overweight and obesity may take longer than 2years to achieve.

RÉSUMÉ

BACKGROUND: The Child Health Initiative for Lifelong Eating and Exercise is a multicomponent obesity-prevention intervention, which was evaluated among Head Start (HS) centers in American Indian and predominantly Hispanic communities in rural New Mexico. This study examines the intervention's foodservice outcomes: fruits, vegetables, whole grains, discretionary fats, added sugars, and fat from milk served in meals and snacks. METHODS: Sixteen HS centers were randomized to intervention/comparison groups, following stratification by ethnicity and preintervention median body mass index of enrolled children. The foodservice component included quarterly trainings for foodservice staff about food purchasing and preparation. Foods served were evaluated before and after the 2-year intervention, in the fall 2008 and spring 2010. RESULTS: The intervention significantly decreased fat provided through milk and had no significant effect on fruit, vegetables and whole-grain servings, discretionary fats, and added sugar served in HS meals and snacks. When effect modification by site ethnicity was examined, the effect on fat provided through milk was only found in American Indian sites. CONCLUSIONS: Foodservice interventions can reduce the amount of fat provided through milk served in HS. More research is needed regarding the implementation of foodservice interventions to improve the composition of foods served in early education settings.

RÉSUMÉ

Background Limited research addresses interventions to increase physical activity among American Indian and Hispanic preschool-aged children living in rural areas. We examined the impact of a Head Start-based intervention (Child Health Initiative for Lifelong Eating and Exercise [CHILE]) on physical activity at home. Method Sixteen Head Start centers in predominantly Hispanic or American Indian communities were group randomized to the six-component intervention or a comparison group for 2 years. Structured surveys were administered at four assessment times to a convenience sample of caregivers of 655 children in the study. Multilevel modeling was used to assess the effects of the intervention on physical activity. Results The relative change in physical activity in the intervention group compared with the comparison group over the 2-year period was 1.56 (95% confidence interval [1.02, 2.38]; p = .04). Among specific promoted activities (ball playing, dancing, active games, jumping, and walking), dancing increased significantly in the intervention compared with the comparison group (2.9; 95% confidence interval [1.2, 7.1]; p = .02). Conclusions The CHILE intervention was effective at increasing physical activity at home in preschool children in priority populations. Future research should focus on increasing family involvement and strengthening messaging about physical activity in these populations.

RÉSUMÉ

Associations between food insecurity and overweight/obesity, feeding behaviors, and public food assistance utilization have been explored to a greater extent among adults and adolescents than among young children. This cross-sectional study examines a subset of pre-intervention implementation data (n = 347) among families participating in the Child Health Initiative for Lifelong Eating and Exercise (CHILE) study conducted in rural New Mexico among predominantly Hispanic and American Indian Head Start centers. No significant relationships emerged between food insecurity and child overweight/obesity, certain feeding behaviors, or public food assistance utilization. Additional research is necessary to understand relationships between food insecurity and child overweight/obesity status, use of public assistance benefits, and certain feeding behaviors among rural preschool-aged children in predominantly Hispanic and American Indian communities.

RÉSUMÉ

OBJECTIVES: This study examined WIC policy change effects on dietary intake of preschool children from WIC-participating households in rural New Mexico communities. METHODS: Dietary intake of children enrolled in Head Start in 8 communities was compared before and after 2009 WIC food package changes. RESULTS: Following the policy change, participants reported significantly increased consumption of lower-fat milk, reduced consumption of saturated fat (grams), and decreased consumption of vegetables without potatoes. No significant differences in fruit, fruit juice, vegetables including potatoes, whole-grains and saturated fat (percent-energy) consumption were observed. CONCLUSIONS: WIC policy changes have the potential to improve children's saturated fat intake. More research with robust designs is necessary to examine long-term effects of WIC policy changes.

RÉSUMÉ

BACKGROUND: Obesity is a major concern among American Indians and Hispanics. The Child Health Initiative for Lifelong Eating and Exercise (CHILE) is an evidence-based intervention to prevent obesity in children enrolled in 16 Head Start (HS) Centers in rural communities. The design and implementation of CHILE are described. METHODS: CHILE uses a socioecological approach to improve dietary intake and increase physical activity. The intervention includes: a classroom curriculum; teacher and food service training; family engagement; grocery store participation; and health care provider support. RESULTS: Lessons learned from CHILE include the need to consider availability of recommended foods; the necessity of multiple training sessions for teachers and food service; the need to tailor the family events to local needs; consideration of the profit needs of grocery stores; and sensitivity to the time constraints of health care providers. CONCLUSIONS: HS can play an important role in preventing obesity in children. CHILE is an example of a feasible intervention that addresses nutrition and physical activity for preschool children that can be incorporated into HS curricula and aligns with HS national performance standards.

RÉSUMÉ

BACKGROUND: The need to conduct formative assessment to inform the development of interventional studies has been increasingly recognized in community-based health research. While this purpose alone may provide sufficient justification to conduct formative assessment, researchers are also recognizing the importance of such efforts with regard to partnership building. PURPOSE: This article reports a formative assessment process in a large scale randomized controlled trial in New Mexico aimed at preventing obesity in rural American Indian and Hispanic children in Head Start programs. METHODS: We interviewed Head Start staff and conducted observations to understand the context of food service and physical activity in these sites. We also collected data from other community partners, including grocery store managers and primary care providers, to assess appropriate strategies regarding their engagement in the study. RESULTS: Formative assessment findings helped modify the planned intervention while allowing for variation relevant to cultural and Head Start organizational conditions in each community. Rather than view formative assessment only as a planning phase of the research, our experience illustrates the need to conceptualize these activities more broadly. DISCUSSION: Integrating formative assessment and participatory research raises the need to address the challenge of ensuring standardization and consistency across varied community settings, the evolving nature of initial formative relationships and the need to build trust in academic/community partnerships. TRANSLATION TO HEALTH EDUCATION PRACTICE: In our work with American Indian and Hispanic communities in New Mexico, formative assessment represents a partnership building opportunity.
