Background: Visceral Adiposity Index (VAI) is a formula to estimate visceral fat accumulation which has been reported to have a better prediction for type 2 diabetes mellitus (T2DM) in Caucasian population. This systematic review is proposed to inquire whether VAI can be used as a predictor of T2DM in Asian population with different body composition compared to the Caucasian.
Methods: All studies performed in Asia and published in English on VAI prediction on the incidence of T2DM were included. The search keywords used in Pubmed and Cochrane database were visceral adiposity index, VAI and T2DM.
Results: Seven included studies, of which six studies were conducted in China and one in Iran. Four studies were prospective cohorts and the other three were cross-sectional. The largest study population were 7639 subjects, while the longest observation period was 15 years. This study found that VAI can be used as a predictor of T2DM in Asian population with better prediction values compared to Caucasian population. The reported odds ratio or hazard ratio ranged from 1.2 to 3.6.
Conclusions: VAI is a practical formula used to estimate the accumulation of visceral fat which can be used as a predictor for T2DM in Asian population.
