目的分析1985-2005年山东省大学生BMI指数的分布状况,为控制青少年超重和肥胖提供依据。方法依据1985,1995和2005年山东省大学生体质健康调研资料,绘制BMI指数分布曲线。结果在1985-2005年20 a间,山东省大学生BMI指数在低百分位数几乎无明显变化,差异主要表现在高百分位数,曲线在高百分位数表现出明显的“迅猛上升”态势,如男、女生P95分别由1985年的23.12,22.78增长到2005年的26.72,24.86,分别增长了15.57%和9.13%。BMI指数分布区间越来越大,曲线右移,尤其是“右尾”不断延长,提示高BMI个体所占的比例不断上升。结论山东省大学生BMI指数分布曲线随年代发生明显变化,肥胖和超重率不断上升,已成为严重的公共卫生问题。
Objective To analyze the distribution of BMI index of college students in Shandong province from 1985 to 2005 and provide the basis for controlling the overweight and obesity of adolescents. Methods According to the survey data of college students’ physical health in 1985, 1995 and 2005, the distribution curve of BMI index was drawn. Results In the period from 1985 to 2005, the BMI index of Shandong college students showed almost no significant change in the low percentile, the difference was mainly in the high percentile, and the curve showed obvious “fast” in the high percentile Rising “situation, such as male and female P95 increased from 23.12,22.78 in 1985 to 26.72,24.86 in 2005, up by 15.57% and 9.13% respectively. BMI index distribution range is bigger and bigger, the curve moves to the right, especially the ”right tail" continues to extend, suggesting that the proportion of high BMI individuals continue to rise. Conclusion The distribution curve of BMI index of college students in Shandong Province has changed significantly with the age. The rate of obesity and overweight has been rising continuously and has become a serious public health problem.
