Abstract:
Objective:To investigate the relationship between obesity and fasting blood glucose levels in elderly people over 65 years old without diabetes mellitus in Sheshan Town. Methods:The physical examination data of the elderly in Sheshan Town in 2018 were collected， including body mass index （BMI）， waist circumference （WC）， waist-to-hip ratio （WHR）， waist-to-height ratio （WHtR）. Patients who had been diagnosed with diabetes were excluded. Fasting blood glucose level was determined by glucokinase method. Chi-square test was used to compare the fasting blood glucose levels in men and women with different obesity status. Logistic regression analysis was used to explore the relationship between obesity-related indicators and diabetes mellitus. Results:A total of 4 434 subjects were included in this study， including 1 921 males and 2 513 females， with a median age of 71 years. The average fasting blood sugar level was （5.87±1.48）mmol/L and the prevalence of diabetes was 11.9% （526/4 434）. The correlation coefficients of BMI， WC， WHtR and WHR with fasting blood glucose level were 0.149， 0.125， 0.21 and 0.075 （P<0.001）， respectively. Multivariate logistic regression analysis showed that the risk of diabetes in the elderly increased with the obesity of WC， WHR and WHtR. BMI and WHtR were significantly higher in the elderly， but after further adjusting by waist circumference， they were not significantly correlated with diabetes mellitus. Conclusion:The incidence of diabetes mellitus in the elderly may be related to obesity， especially centripetal obesity. Establishing a suitable regression model can predict the incidence of diabetes mellitus and provide a scientific and reliable basis for the prevention and treatment of the disease.
