上海市莘庄社区中老年人体质量指数与常见慢性病关系研究

Relationship between chronic disease and body mass index of middle-aged and elderly people in Xinzhuang Town of Shanghai

目的:了解上海市莘庄社区中老年人在25岁及当前体质量指数(BMI)与目前社区常见慢性病的关系。方法:采取问卷调查及现场测量方式分别获取144名中老年人的慢性病史、25岁时及当前的身高、体质量、骨密度值等数据,通过统计学分析其25岁时BMI及目前BMI分别与慢性病的关联性。结果:单因素分析结果显示:25岁时不同BMI分级的中老年人糖尿病及骨质疏松症的患病率差异均有统计学意义(P<0.05和P<0.01),而当前不同BMI分级的中老年人高脂血症的患病率差异有统计学意义(P<0.05)。多因素logistic回归分析显示:25岁时不同BMI中老年人糖尿病和骨质疏松症的患病率差异均有统计学意义(P=0.012和P=0.001),当前不同BMI中老年人糖尿病的患病率差异有统计学意义(P=0.012)。结论:糖尿病与25岁时BMI呈正相关关系,骨质疏松症与25岁BMI呈负相关关系;糖尿病、高脂血症与当前的BMI呈正相关关系。从青年到老年,合理控制体质量是减少老年慢性病发生的有效方式之一。

Objective：To investigate the relationships between the incidence of chronic disease and body mass index（ BMI） at the age of 25 and now of middle-aged and elderly people in Xinzhuang Town of Shanghai. Methods：The chronic disease history,and height, weight and bone mineral density at the age of 25 and now of middle-aged and elderly people were investigated by questionnaire survey and on-site measurement methods. The relationships between chronic disease and BMI at the age of 25 and now were statistically analyzed. Results：Single factor analysis results showed that the differences of the incidence of diabetes and osteoporosis in different BMI at the age of 25 of middle-aged and elderly people were statistically significant（P〈0. 05 and P〈0. 01）,the difference of the incidence of hyperlipemia in middle-aged and elderly people with different BMI was statistically significant（P 〈0. 05）. Multiariable logistic regression analysis results showed that the differences of the incidence of diabetes and osteoporosis in different BMIs at the age of 25 of middle-aged and elderly people were statistically significant（P=0. 012 and P=0. 001）,the difference of the incidence of diabetes in middle-aged and elderly people with different BMI was statistically significant（P=0. 012 and P=0. 001）. Conclusions：Diabetes and osteoporosis are positively and negatively related with BMI at the age of 25,respectively. Diabetes and hyperlipidemia are positively correlated with the BMI of middle-aged and elderly people. From young to old,the reasonable weight control is one of effective way to decrease the occurrence of chronic disease.
