[Effects of new body shape index on prevalence of diabetes mellitus and fasting blood glucose].

Objective: To evaluate the effects of a new body shape index (ABSI) on the prevalence of diabetes mellitus (DM) and Fasting blood-glucose (FBG) in elders in Chengdu.
Methods: In May 2007, a total of 685 subjects were recruited by random sampling, with an average age of (63.3±10.2) years. All subjects received standardized questionnaires, physical examinations and laboratory tests for analyzing the relationship between ABSI with the prevalence of FBG and DM.
Results: The overall trend of FBG increased with rising ABSI (P<0.001). But the impact of ABSI on the prevalence trend of DM was not obvious (P=0.334). According to logistic regression analysis adjusting for confounders, ABSI was not a risk factor of DM. Relative to the lowest quartile of ABSI, the odds ratio of DM prevalence was 1.093 (95% CI: 0.617-1.937, P=0.761), 0.844 (95% CI: 0.469-1.517, P=0.570) and 0.684 (95% CI: 0.373-1.256, P=0.221) at the second, third and fourth quartiles respectively.
Conclusion: ABSI is not associated with the prevalence of DM in middle-aged and elderly people in Chengdu. Further cohort study are required for clarifying the ethnic difference of ABSI.
