Dietary intakes and physical activity among preschool-aged children living in rural American Indian communities before a family-based healthy lifestyle intervention.

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.
