Resurvey was conducted in 2015. Non-conditional logistic regression was used to investigate association between dietary GL and diabetes mellitus. 【Results】During 2011~2015, 102 of 768 participants were diagnosed diabetes mellitus and the cumulative rate was 13.3%.Participants were categorized into 4 groups according to quartiles of energy-adjusted GL. The multivariable-adjusted odds ratios across quartiles of energy-adjusted GL was 1.00, 0.96, 1.83, 2.11(95% CI, 1.09 ~ 4.07)(P for trend 0.01). 【Conclusion】Among middle-aged and elderly people in Guangzhou, China, dietary GL may be one of the most important dietary factors affecting the incidence of diabetes mellitus.
