背景资料：一些研究报告了儿童早期体重与以后生活中身体成分之间的关联，如双能X射线吸收测定法（DXA）所测量的;然而，这些研究都没有调查东亚人群。在日本的人口，我们研究了3岁时的体重和身体成分之间的关联，在11岁时，测量使用DXA.Methods：源人口是726名五年级学生就读于3所公立学校在静冈县，日本从2008年至2010年。居住在研究地区的所有儿童都在这三所学校中的一所上学。DXA用于获得身体成分的数据，并使用妇幼保健手册计算体重指数（BMI）。一般线性模型用于统计分析。结果：我们能够分析数据的身体成分在11岁和BMI在幼儿期为550名儿童。3岁时的BMI和从出生到3岁时BMI z评分的变化与11岁时的骨矿物质含量（BMC）、无脂肪软组织质量（FFSTM）和脂肪质量（FM）呈正相关。调整混杂因素后，平均BMC，FFSTM，FM显着低于儿童体重不足的儿童在3岁和显着高于儿童体重超重的儿童在3岁，与正常体重的儿童在3岁的值相比。结论：在日本儿童中，3岁的体重预测身体组成在11岁。
Background: A few studies reported an association between body weight during early childhood and body composition in later life, as measured by dual-energy X-ray absorptiometry (DXA); however, none of those studies investigated an East Asian population. In a Japanese population, we examined the association between body weight at age 3 years and body composition at age 11 years, as measured using DXA.Methods: The source population was 726 fifth-grade school children enrolled at 3 public schools in Shizuoka Prefecture, Japan from 2008-2010. All children who lived in the study area went to 1 of these 3 schools. DXA was used to obtain data on body composition, and the Maternal and Child Health Handbook was used to calculate body mass index (BMI). The general linear model was used for statistical analysis.Results: We were able to analyze data on body composition at age 11 years and BMI in early childhood for 550 children. BMI at age 3 and change in BMI z-score from birth to age 3 were positively associated with bone mineral content (BMC), fat-free soft tissue mass (FFSTM), and fat mass (FM) at age 11. After adjusting for confounding factors, mean BMC, FFSTM, and FM were significantly lower among children who were underweight at age 3 and significantly higher among children who were overweight at age 3, as compared with values for normal-weight children at age 3.Conclusions: Among Japanese children, body weight at age 3 years predicts body composition at age 11 years.
