湖南省中年知识分子体重指数调查

Investigation of BMI of the meddle-aged intellectuals in Hunan Province

采用随机整体抽样调查法,对湖南省14个市、州的45～55岁3294名中年知识分子的身体形态、生理机能等指标进行观察测定。结果显示:湖南省中年知识分子男性45～49岁组体重指数(BMI)平均为25.1±2.82,50～55岁组为27.7±3.22;女性45～49岁组平均为24.7±3.13,50～55岁组为26.3±3.30。其中50～55岁同性别BMI高于年龄45～49岁者(P<0.05),且BMI与安静的心率、血压、体脂百分率以及肺活量有密切关系;湖南省中年知识分子BMI随着年龄的增加而增加,并与血压、皮褶厚度以及体脂百分比呈正相关,而与肺活量呈负相关;BMI作为评价体质与健康、预防心血管疾病具有重要的意义。

The method of doing the experiment is to get the samples of the physical feathers from 3 294 intellectuals aged 45～55 from 14 cities in Hunan province and then to test their physiological organism. The result of the experiment shows that the average index of those from 45 to 49 is 25.1±2.82;of those from 50～55 is 27.7±3.22; and females from 45～49 is 24.7±3.13,and those from 50～55 is 26.6±3.30. The BMI of the persons of the same sex and the same age of 50～55 is higher than those from 45～49.(P<0.05). BMI has something to do the heart-beating rate, blood pressure,fat and lungs energy. To conclude, the BMI of the intellectuals in Hunan is increasing with the age and the proportion of blood pressure, lungs energy and fat goes directly with BMI,so it is of great importance to prevent the arteries from being hardened if BMI is seen as assessment to assess people's physique and health.
