目的 了解单纯性肥胖对中学生生理功能的影响。 方法 检出单纯性肥胖者 2 5 5人 ,按 1∶1配对原则 ,随机抽取非肥胖者 2 5 5人作对照。测量二组人群的血压、脉搏、肺活量 ,并用概率单位回归分析方法计算女生月经初潮平均年龄。 结果 肥胖组的收缩压、舒张压、脉搏显著高于对照组 ,而肺活量及其指数却显著低于对照组 ,其差值随肥胖程度增加而加大。肥胖者发生血压偏高的危险性是对照组的 15 .8倍。肥胖组女生月经初潮率显著高于对照组 ,且初潮平均年龄早 0 .95岁。 结论 肥胖可引起一系列生理功能损伤 ,应积极提早预防儿童少年肥胖的发生。
Objective To understand the effect of simple obesity on the physiological function of middle school students. Methods A total of 25 5 obese individuals were detected. According to the principle of 1: 1 matching, 25 5 non-obese individuals were randomly selected as control. The blood pressure, pulse rate and vital capacity of the two groups were measured, and the average age of the girls was calculated by regression analysis with probability units. Results The systolic blood pressure, diastolic blood pressure and pulse in obese group were significantly higher than those in control group, while the vital capacity and index of obesity group were significantly lower than those in control group. The difference increased with the increase of obesity. Obese high blood pressure risk of 15.8 times the control group. The menarche rate of obese girls was significantly higher than that of the control group, and the average age of menarche was as early as 0.95 years. Conclusion Obesity can cause a series of physiological function damage, should be actively and early prevention of obesity in children and adolescents.
