摘要：

目的  关注中国汉族学生两性体格差异的时空变化特征。 方法  基于1985~2019年中国学生体质与健康调研数据，选取中国19~23岁汉族学生为研究对象（参与身高测量的学生343 928例，参与体质量测量的学生344 029例），观察两性身高差异指数（SSDI）和两性体质量差异指数（SBMDI）在不同时代和区域间的分布情况，同时关注这两项指数与人均消费支出的相关性。 结果  中国汉族学生的SSDI和SBMDI均随年代推移而逐渐增大。学生SSDI和SBMDI在南、北区间的分布上有较多的相似性。与SSDI相比，SBMDI存在明显的城乡差异，且与人均消费支出存在显著正相关。 结论  女性缓冲假说存在一定的时空适用范围，而且易受环境影响的性状能更有效地支持该假说。

Abstract:

Objective  To investigate the spatiotemporal variations in sexual size dimorphism among Chinese Han students.  Methods  Based on the eight students’physical and healthy investigations, the data on the stature and body mass were systematically collected for 343 928 and 344 029 Chinese Han students aged 19 to 22 years from 1985 to 2019, respectively. The sexual stature dimorphism index (SSDI) and sexual body mass dimorphism index (SBMDI) were employed to analyze the distribution in different periods and regions. In addition, we focused the relationships between these two indices and the per capita consumption expenditure. Results  Positive secular trends were observed in the SSDI and SBWDI among Chinese Han students throughout the 1985 to 2019 period. Notable similarities were identified in the SSDI and SBWDI between northern and southern students. Compared with the SSDI, the SBWDI exhibited significant disparities between urban and rural areas, and demonstrated a positive association with the per capita consumption expenditure.  Conclusion  The female buffering hypothesis possesses a limited range of spatiotemporal adaptability, and the trait more susceptible to environmental influences is better suited to test this hypothesis.
