摘要
Visceral Adiposity Index (VAI) is a sex-specific index of visceral adiposity based on body mass index, waist circumference, triglycerides and high-density lipoprotein cholesterol. This study aims to demonstrate the association of VAI and its longitudinal transition patterns with type 2 diabetes mellitus (T2DM) in middle-aged and older Chinese.Data from the China Health and Retirement Longitudinal Study (2011, 2013, 2015, and 2018) were analysed. Participants were classified into high- and low-VAI groups at baseline, and subsequently into four transition patterns during follow-up (2011-2015): maintained-high, maintained-low, high-to-low, and low-to-high VAI. Multivariable Cox frailty models with random effects were used to assess the associations of VAI and its transitions with T2DM.A total of 7245 participants were analysed, among which 818 developed T2DM by 2018. A positive association between baseline high-VAI levels and T2DM was observed (HR = 1.49, 95% CI: 1.27-1.75). Compared with people with maintained low-VAI pattern during follow-up, those with transition patterns of maintained-high VAI, high-to-low VAI, and low-to-high VAI were at higher risk of T2DM (HR = 1.97, 1.52, and 1.56, respectively, all p < 0.05). The risk of T2DM decreased significantly in the high-to-low VAI group as compared to the maintained-high VAI group (HR = 0.77, 95% CI: 0.60-0.99).This study demonstrated the significant associations of baseline VAI and its transitions with the risk of new-onset T2DM. Early prevention efforts are needed to control the development of T2DM in Chinese with high-VAI levels.
