目的分析中国1985—2010年18岁汉族男生身高、体重秩次变化,为相关标准的制定、促进儿童少年生长发育提供科学依据。方法依据1985,1991,1995,2000,2005,2010年中国学生体质调研报告中18岁汉族男生的身高、体重数据排秩次,分析南北方各省市间的差异。结果 25年间,中国大陆18岁城市汉族男生身高增长了1.19~5.38 cm(平均2.48 cm),体重增长了3.00~12.06 kg(平均6.64 kg)。北方省市秩次排名普遍高于南方,而同在北方或南方省市,经济发展好的省市相应群体的秩次排名也较高。结论 1985—2010年中国大陆各省市18岁汉族男生群体的身高、体重均有较明显增长,但其增长存在地区差异。
Objective To analyze the changes of height and weight rank of 18-year-old Chinese boys from 1985 to 2010 in China, and to provide a scientific basis for the establishment of relevant standards and promotion of the growth and development of children and adolescents. Methods Based on the height and weight rankings of 18-year-old Han boys from 1985 to 1991, 1995, 2000, 2005 and 2010, the differences between the provinces and cities in North and South China were analyzed. Results During the 25 years, Han boys of 18-year-olds in Mainland China increased their height by 1.19-5.38 cm (average 2.48 cm) and weight by 3.00-12.06 kg (average 6.64 kg). Rankings of northern provinces rank generally higher than those of the South, while rankings of corresponding groups in economically developed provinces and cities are also higher in the northern and southern provinces and cities. Conclusion The height and weight of 18-year-old Han boys from 1985 to 2010 in provinces and cities all over the country increased significantly, but there were regional differences in their growth.
