目的探讨学龄前儿童骨密度水平变化及环境、膳食等影响因素相关性。方法选择2014年1月至2014年12月进行骨密度检测的500例儿童,通过调查问卷的方式调查儿童生活环境及膳食情况。结果不挑食,蔬菜水果、豆制品及奶制品正常摄入,少摄入碳酸饮料,日照频繁,睡眠质量良好,运动时间适宜,不常被动吸烟儿童骨密度明显提高,差异具有统计学意义(P<0.05)。结论学龄前儿童骨密度水平受环境和膳食因素影响,保证良好的作息习惯和合理饮食对提高骨密度水平具有重要的临床意义。
Objective To investigate the relationship between the changes of bone mineral density (BMD) and environment, diet and other influencing factors in preschool children.
