To examine the relationship between intake of whole grains and BMI Z-score in rural children.
General linear models and logistic regression were used to examine the cross-sectional associations between whole grain intake and BMI Z-score, prevalence and odds ratios of overweight and obesity. Dietary intake was assessed using the Block Food Screener for ages 2-17 years. Children were classified into three categories according to servings of whole grain intake: <1·0 serving/d, 1·0-1·5 servings/d and >1·5 servings/d.
The CHANGE (Creating Healthy, Active and Nurturing Growing-up Environments) study, an obesity prevention intervention in elementary schools in eight rural US communities in California, Mississippi, Kentucky and South Carolina.
Seven hundred and ninety-two children attending 3rd-6th grade.
After adjusting for age, sex, race/ethnicity, physical activity and state of residence, whole grain intake was inversely associated with BMI Z-score (0·90 v. 0·61 in the lowest v. the highest whole grain intake category; P trend = 0·01). Children who consumed >1·5 servings of whole grains/d had a 40 % lower risk of being obese (OR = 0·60; 95 % CI 0·38, 0·95, P = 0·02) compared with children who consumed <1·0 serving/d. Further adjustment for potential dietary predictors of body weight (fruit, vegetable and dairy intakes) did not change the observed associations.
Increasing the intake of whole grains as part of an overall healthy lifestyle may be beneficial for children to achieve and maintain a healthy weight.
研究全谷物摄入量与农村儿童 BMI 得分的关系。
采用一般线性模型和逻辑回归分析全谷物摄入量与 BMI 得分、超重和肥胖患病率及比值比之间的横断面关系。采用 Block 食物筛选器评估 2-17 岁儿童的饮食摄入量。根据全谷物摄入量的份数将儿童分为三组：<1·0 份/d、1·0-1·5 份/d 和 >1·5 份/d。
CHANGE（创建健康、积极和培育成长环境）研究，在美国加利福尼亚、密西西比、肯塔基和南卡罗来纳的 8 个农村社区的小学中进行的肥胖预防干预。
792 名 3-6 年级的儿童。
在校正年龄、性别、种族/民族、身体活动和居住州后，全谷物摄入量与 BMI 得分呈负相关（最低组为 0·90，最高组为 0·61；P 趋势=0·01）。与每天摄入<1·0 份全谷物的儿童相比，每天摄入>1·5 份全谷物的儿童肥胖的风险降低了 40%（OR=0·60；95%CI 0·38，0·95，P=0·02）。进一步调整潜在的膳食体重预测因素（水果、蔬菜和乳制品摄入量）并没有改变观察到的相关性。
作为整体健康生活方式的一部分，增加全谷物的摄入量可能有益于儿童保持健康体重。
