我们评估了1985-2014年新疆儿童和青少年按年龄组和营养状况的体质变化趋势。在1985年、1995年、2005年和2014年提取了49,357名7-18岁的参与者的数据。生长和营养状况的定义采用世界卫生组织的定义。身体健康指数（PFI）计算为每次调查中测量的六个组成部分的总和。采用非线性回归方法研究体重指数（BMI）与PFI之间的关系。以1985年为参照，1995年PFI上升至2,2005年急剧下降至-2.8,2014年为-3.8。正常体重的患病率从1985年的87.5%上升到1995年的89.4%，然后下降到75.2%，与PFI的变化一致。BMI与PFI呈倒u型曲线关系。在1985-1995年期间，13-15岁的男孩和16-18岁的女孩增加最多；1995-2005年期间，10-12岁的男孩和女孩降幅最大。我们的研究为南疆地方政府提供营养补贴和项目提供了参考，表明需要更多地关注7-12岁儿童。
We assessed trends in physical fitness by age group and nutrition status among children and adolescents in Xinjiang during 1985-2014. The data of 49,357 participants aged 7-18 were extracted in 1985, 1995, 2005, and 2014. Growth and nutritional status were defined using World Health Organization definitions. A physical fitness indicator (PFI) was calculated as the sum of six components measured in every survey. The relationship between body mass index (BMI) and PFI was investigated using nonlinear regression. Taking 1985 as a reference, PFI increased to 2 in 1995 and then fell sharply to -2.8 in 2005 and -3.8 in 2014. The prevalence of normal weight increased from 87.5% in 1985 to 89.4% in 1995 and then decreased to 75.2%, consistent with the change in PFI. The relationship between BMI and PFI showed an inverted U-shaped curve. The largest increment occurred in boys aged 13-15 and girls aged 16-18 during 1985-1995; the largest decline occurred in boys and girls aged 10-12 during 1995-2005. Our research provides a reference for local governments providing nutrition subsidies and projects in southern Xinjiang, indicating that greater attention is needed for children aged 7-12.
