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.
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).
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.
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.
报告美国印第安农村社区学龄前儿童在参与家庭健康生活方式干预之前的饮食摄入和身体活动情况,并将数据与当前特定年龄的建议进行比较。
对象/设计:135名居住在美国印第安农村社区的学龄前儿童在参与为期2年的随机健康生活方式干预之前提供了饮食和身体活动数据。通过三次24小时饮食回顾评估营养素、食物及添加糖的摄入量,并与美国国家科学院的膳食参考摄入量、美国农业部的食物指南金字塔以及美国心脏协会的建议进行比较。将看电视时间以及中度和剧烈活动时间与食物指南金字塔和美国儿科学会的建议进行比较。
通过计算达到建议的百分比,将营养素、食物组、添加糖摄入量以及看电视时间和中度或剧烈活动时间与建议进行比较。非参数检验确定了不同年龄组以及正常和超重儿童(体重指数<第85百分位数和>或=第85百分位数)在饮食和身体活动方面的差异。
平均营养素摄入量达到了建议标准,但食物组摄入量未达到。2至3岁儿童的水果和蔬菜平均摄入量分别为每天0.36杯水果和0.45杯蔬菜,4至5岁儿童为每天0.33杯水果和0.48杯蔬菜。两个年龄组报告的添加糖摄入量均超过50克,超过了16克的建议量。超重儿童与正常体重儿童相比,含糖饮料摄入量显著更高(8.0±0.10杯/天对5.28±0.08杯/天,P<0.01)。平均而言,所有儿童报告每天看电视2.0小时,超重和正常体重儿童在总看电视时间和不看电视时间方面存在显著差异(8.52±0.6小时/天对6.54±0.6小时/天,P<0.01)。所有儿童每天进行中度或剧烈活动的时间均<20分钟。
总体而言,该样本中的儿童未达到食物指南金字塔对水果或蔬菜的建议摄入量,且超过了添加糖摄入量建议。看电视时间以及家中电视开启时间普遍较长,同时中度或剧烈活动水平较低。我们研究的“健康儿童,强壮家庭”干预措施有潜力改善居住在美国印第安农村社区的学龄前儿童的营养和身体活动状况。
