RESUMO
OBJECTIVE: To report dietary intake and physical activity among preschool-aged children living in rural American Indian communities before participation in a family-based healthy lifestyle intervention and to compare data to current age-specific recommendations. SUBJECTS/DESIGN: One hundred thirty-five preschool-aged children, living in rural American Indian communities, provided diet and physical activity data before participating in a 2-year randomized healthy lifestyle intervention. Three 24-hour dietary recalls assessed nutrient and food and added sugar intake, which were compared to the National Academy of Science's Dietary Reference Intakes, the US Department of Agriculture's MyPyramid, and American Heart Association recommendations. Time watching television and moderate plus vigorous activity was compared to MyPyramid and American Academy of Pediatrics recommendations. STATISTICAL ANALYSIS: Nutrient, food group, added sugar intake, and time watching television and in moderate or vigorous activity were compared to recommendations by computing the percent of recommendations met. Nonparametric tests identified differences in diet and physical activity among age groups and normal and overweight children (body mass index <85th and > or = 85th percentile). RESULTS: Average nutrient intakes met recommendations whereas food group intakes did not. Mean fruit and vegetable intakes for 2- to 3-year-olds were 0.36 c/day fruit and 0.45 c/day vegetables and, for 4- to 5-year-olds, 0.33 c/day fruit and 0.48 c/day vegetables. Both age groups reported consuming more than 50 g added sugar, exceeding the recommendation of 16 g. Overweight vs normal weight children reported significantly more sweetened beverage intake (8.0+/-0.10 vs 5.28+/-0.08 oz/day, P<0.01). On average, all children reported watching television 2.0 hours/day and significant differences were observed for total television viewing and nonviewing time between overweight and normal weight children (8.52+/-0.6 vs 6.54+/-0.6 hours/day, P<0.01). All children engaged in <20 minutes/day of moderate or vigorous activity. CONCLUSIONS: Overall, children in this sample did not meet MyPyramid recommendations for fruits or vegetables and exceed added sugar intake recommendations. Television viewing time and time when the television was on in the home was highly prevalent along with low levels of moderate or vigorous activity. The Healthy Children Strong Families intervention we studied has potential for improving nutrition and physical activity among preschool-aged children living in rural American Indian communities.

We designed an obesity prevention intervention for American Indian families called Healthy Children, Strong Families using a participatory approach involving three Wisconsin tribes. Healthy Children, Strong Families promotes healthy eating and physical activity for preschool children and their caregivers while respecting each community's cultural and structural framework. Academic researchers, tribal wellness staff, and American Indian community mentors participated in development of the Healthy Children, Strong Families educational curriculum. The curriculum is based on social cognitive and family systems theories as well as on community eating and activity patterns with adaptation to American Indian cultural values. The curricular materials, which were delivered through a home-based mentoring model, have been successfully received and are being modified so that they can be tailored to individual family needs. The curriculum can serve as a nutrition and physical activity model for health educators that can be adapted for other American Indian preschool children and their families or as a model for development of a culturally specific curriculum.
