我国成年人体质的年龄变化特点和趋势分析

取2000年全国国民体质监测20—59岁成年人(计151，656个样本)相关指标数据，用曲线拟合的方法，找出主要指标变化的峰值年龄和指标变化的速率。主要结论有：成年男子体丰度在45—49岁左右，女子在55—59岁左右，发生了较大的转折变化；成年男、女安静心率的高低将会直接影响台阶指数的大小；收缩压、舒张压随年龄递增而单调增加；用“肺活量／体重”指标的线性方程(男：y=70．25—0．47x；女：y=59．08—0．42x)，评价肺功能随年龄变化的意义更大；男子握力在31-32岁，女子握力在35—36岁，发生了较大的下降转折变化，其他大多数男、女素质指标的成绩呈现单调下降的趋势。

An Analysis of Age Change Features and Trend of Physique in Chinese Adults

Data from the National Physique Survey 2000 with adults aged 20-59 (151,656 samples) were used with curve fitting to find out the peak ages for changes in major indices and their change rate. Conclusions. Turning-point changes in abundance were discerned at approx. 45-49 years for men and at approx. 55-59 years for women. Resting heart rates in men and women affected step-test indices. Systolic pressure and diastolic pressure increased monotonously with age. The vital capacity/body weight index proved it more significant to evaluate change with age in pulmonary functions using a linear equation (y=70.25-0.47x for men; y=59.08-0.42x for women). Turning-point decreases in grip were observed at 31-32 years for men and at 35-36 years for women. Most other indices were on the monotonous decrease for the two groups.
