To explore the correlation between visceral fat index(CVAI) and the incidence of diabetes in Chinese elderly population.
The data were obtained from the China Health and Retirement Longitudinal Survey(CHARLS) 2011 and 2015 waves. A total of 2 295 elderly people aged ≥60 years were included. Binary logistic regression was used to analyze the correlation between CVAI and the incidence of diabetes. The restricted cubic spline(RCS) method was used to test the dose-response relationship. Subgroup analysis was performed according to BMI.
333(14.50%) of the 2295 elderly participants developed diabetes during the 4-year follow-up period. CVAI were divided by quartiles. There were statistically significant differences in baseline FBG, HBA1c, SBP, DBP, TG, TC, HDL-C, LDL-C, UA, gender, smoking status, drinking status, hypertension history and follow-up incident diabetes among groups(P<0.05). Compared with the group with lowest quartile of CVAI Q1, the OR(95% CI) in the group the highest quartile of CVAI Q4 was 1.96(1.37-2.83). The restricted cubic splines model results showed that the higher CVAI accompanied by higher risk of incident diabetes in the elderly. Subgroup analysis showed that CVAI was independently associated with incident diabetes in both non-overweight and overweight/obese groups.
There is a positive association between CVAI the risk of diabetes mellitus in the elderly population. The control of visceral fat in the elderly is helpful to prevent the occurrence of diabetes.
