背景：肥胖和骨质疏松起源于儿童时期，两者都受饮食摄入和身体活动的影响。然而，关于在生命早期同时促进低脂肪量和高骨量积累的饮食构成的信息很少。目的：我们的目的是确定3.8-7.8岁儿童中与脂肪和骨量相关的饮食模式。设计：共325名儿童提供了4个独立研究年的13次访问数据（年龄范围：3.8-4.8岁，bb0 4.8-5.8岁，bb1 5.8-6.8岁，bb2 6.8-7.8岁）。我们对每个研究年度的双能x射线吸收仪测量的脂肪量和骨量进行了降秩回归，以确定与饮食模式相关的饮食模式。协变量包括种族、性别、身高、体重、能量摄入、钙摄入、通过加速度计测量的身体活动、看电视和户外活动的时间。结果：以大量摄入深绿色和深黄色蔬菜为特征的饮食模式与低脂肪和高骨量有关；高加工肉类摄入量与高骨量有关；高油炸食品摄入量与高脂肪量有关。在所有协变量得到控制后，饮食模式评分仍与脂肪量和骨量相关（P < 0.001-0.03）。结论：从学龄前开始，饮食中多吃深绿色和深黄色蔬菜，少吃油炸食品可能会导致幼儿健康的脂肪和骨量增加。m J . clinn [2010]；92: 294 - 303。
Background: Obesity and osteoporosis have origins in childhood, and both are affected by dietary intake and physical activity. However, there is little information on what constitutes a diet that simultaneously promotes low fat mass and high bone mass accrual early in life.Objective: Our objective was to identify dietary patterns related to fat and bone mass in children during the age period of 3.8-7.8 y.Design: A total of 325 children contributed data from 13 visits over 4 separate study years (age ranges: 3.8-4.8, >4.8-5.8, >5.8-6.8, and >6.8-7.8 y). We performed reduced-rank regression to identify dietary patterns related to fat mass and bone mass measured by dual-energy X-ray absorptiometry for each study year. Covariables included race, sex, height, weight, energy intake, calcium intake, physical activity measured by accelerometry, and time spent viewing television and playing outdoors.Results: A dietary pattern characterized by a high intake of dark-green and deep-yellow vegetables was related to low fat mass and high bone mass; high processed-meat intake was related to high bone mass; and high fried-food intake was related to high fat mass. Dietary pattern scores remained related to fat mass and bone mass after all covariables were controlled for (P < 0.001-0.03).Conclusion: Beginning at preschool age, diets rich in dark-green and deep-yellow vegetables and low in fried foods may lead to healthy fat and bone mass accrual in young children.
