目的:分析学龄前儿童骨密度水平与饮食环境等因素的相关性。方法:选择该院2011年2月~2013年11月在该院就诊的3~7岁儿童376例,经家长许可后做骨密度检测,将不同年龄段儿童的骨密度值进行分析。采用调查问卷形式获得儿童饮食环境等因素的情况。结果:不同年龄段儿童的骨密度呈渐变趋势,3~6岁逐年升高并在6岁时达到峰值,6~7岁趋于稳定。饮食环境好的儿童骨密度显著高于饮食环境差的儿童(P<0.05)。结论:学龄前儿童骨密度基本保持逐年增长趋势,易受饮食环境因素影响,健康的作息、合理的饮食对骨密度水平的增长至关重要。
Objective: To analyze the correlation between bone mineral density and dietary environment in preschool children. Methods: A total of 376 children aged 3 to 7 years were selected from the hospital from February 2011 to November 2013. The bone mineral density (BMD) was measured with the permission of parents and the BMD of children of different ages were analyzed. Using the form of questionnaires for children’s eating environment and other factors. Results: The bone mineral density of children of different ages showed a gradual trend. The age of 3 to 6 years old increased year by year and peaked at 6 years old, and stabilized at 6-7 years old. Bone mineral density in children with better diet environment was significantly higher than that in children with poor dietary environment (P <0.05). Conclusion: The bone mineral density of preschool children keeps increasing year by year, and is easily influenced by dietary environment factors. Healthy rest and reasonable diet are crucial to the growth of bone mineral density.
