[Study of influence of birth weight on risk of chronic diseases and blood uric acid in adulthood].

ABSTRACT

Objective: To understand the influence of birth weight on the risk of chronic diseases, such as hypertension and diabetes, and the relationship between birth weight and serum uric acid in adulthood. Methods: According to the Chinese Adult Chronic Disease and Nutrition Surveillance Program, a total of 1 131 residents aged 18 years and above were enrolled from Hexi, Nankai, Hongqiao, Wuqing, Jinnan, Baodi and Jizhou districts of Tianjin. The data of birth weight and blood pressure of the residents were collected, and fasting venous blood samples were collected from them to detect uric acid, blood glucose and blood lipids levels. The distribution of birth weight of the surveyed population was described, and the relationship between birth weight and chronic diseases, such as hypertension and diabetes, and the blood uric acid level in adulthood were analyzed. Results: The average birth weight of the surveyed population in Tianjin was 3.37 kg, which was higher in males than in females. No matter overweight/obesity, hypertension or diabetes, the prevalence rate of normal birth weight was the lowest in adulthood. After univariate logistic regression analysis and adjusting for age, sex, smoking and drinking status, it was found that compared with normal birth weight, low birth weight had a stronger correlation with diabetes (OR=2.91,95%CI1.46-5.76) and dyslipidemia (OR=1.79,95%CI1.01-3.19) in adulthood. Macrosomia was strongly associated with overweight/obesity in adulthood (OR=1.47, 95%CI1.08-2.01). There was no significant difference in serum uric acid level among the residents with different birth weights. Conclusions: The low birth weight of the surveyed population in Tianjin was closely related to the risk of diabetes and dyslipidemia in adulthood, and the macrosomia was closely related to the risk of overweight/obesity in adulthood.
