目的了解兰州市中年人身体成分的比例结构及身体健康状况。方法采用随机抽样方法调查兰州市209名45～59岁中年人,其中男性78人,女性131人。对研究对象的身体成分数据进行统计分析。结果女性体脂百分比[(30.34±5.27)%]高于男性[(22.57±5.44)%]的体脂百分比,两者与标准值比较,差异有统计学意义(P<0.01)。体质指数男性(25.15±2.92)kg/m2高于女性(24.37±2.80)kg/m2,与标准值比较,差异有统计学意义(P<0.05)。男性去脂体重[(56.99±8.26)kg]高于女性[(43.83±4.66)kg]的去脂体重,两者与标准值比较,差异有统计学意义(P<0.05)。男女中年人体水分与标准值比较,差异无统计学意义(均P>0.05)。结论从测试群体的数据结果发现,兰州市209名中年人的身体成分结构比例存在不合理问题,身体成分比例的不合理是影响健康的潜在因素。
Objective To understand the proportion structure and physical health status of body composition of middle-aged people in Lanzhou. Methods A total of 209 middle-aged 45- to 59-year-old middle-aged people in Lanzhou were surveyed by random sampling method, including 78 males and 131 females. The body composition data were statistically analyzed. Results The percentage of body fat in female was significantly higher than that in male [(30.34 ± 5.27)%] [(22.57 ± 5.44)%], the difference was statistically significant (P <0.01). The body mass index was significantly higher in male (25.15 ± 2.92) kg / m2 than in female (24.37 ± 2.80) kg / m2, compared with the standard value (P <0.05). The lean body mass of [(56.99 ± 8.26) kg] in men was higher than that in females [(43.83 ± 4.66) kg], the difference was statistically significant (P <0.05). Middle-aged men and women compared with the standard value of water, the difference was not statistically significant (P> 0.05). Conclusion According to the data from the test population, it is found that there are unreasonable proportions of body composition in 209 middle-aged people in Lanzhou. The unreasonable proportion of body composition is a potential factor affecting health.
