Abstract:
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.
