Abstract

Background and aim

The purpose of this meta-analysis was to evaluate the dose-response relationship between dietary cholesterol (DC) consumption and the incidence of type 2 diabetes mellitus (T2DM).

Methods and results

Prospective studies with the endpoint of T2DM were included. The Random-effect model weighted by inverse variance was used. Meta-regression and subgroup analyses were conducted to explore the potential sources of heterogeneity by specified study characteristics. Restricted cubic splines regression models were used to estimate the dose-response relationship. 11 prospective studies comprising of 355 230 subjects were included. Compared to lowest DC consumption, highest DC consumption was associated with an increased risk of T2DM (RR 1.15, 95% CI 1.03 to 1.28, P = 0.012; chi-squared = 31.41, I-squared 58.6%, P heterogeneity = 0.003). Subgroup analyses have shown that this positive association was more evident in western countries than in eastern countries (RR 1.19, 95% CI 1.06 to 1.36 VS 1.34, 95% CI 0.84 to 1.29; P subgroup difference = 0.02). For 100 mg/d increment in DC intake, the pooled RR was 1.05, (95% CI 1.04 to 1.07, Plinearity = 0.000, Pnonlinearity = 0.02), 1.06 (95% CI 1.04 to 1.07, Plinearity=0.000), and 1.01 (95% CI 0.98 to 1.05, Plinearity = 0.525) for the incidence of T2DM, in western and eastern countries, respectively.

Conclusions

Our study suggests that there is a positive dose-response association between DC consumption and the incidence of T2DM, especially in western countries.
