- BACKGROUND: Dyslipidaemia commonly coexists with diabetes. We investigated the association of lipid profiles with glucose levels in populations of Asian origin without a prior history of diabetes. METHODS: Cross-sectional data of 10,374 men and 12,552 women aged 30-74 years from 14 cohorts, representing seven populations of Asian origin were jointly analysed. Multivariable adjusted linear regression analyses with standardized regression coefficients (beta) were performed to estimate relationships between lipids and plasma glucose. RESULTS: Within each glucose category, fasting plasma glucose (FPG) levels were correlated with increasing levels of triglycerides (TGs), total cholesterol (TC), TC to high-density lipoprotein (HDL) ratio and non-HDL cholesterol (non-HDL-C) (p < 0.05 in most of the ethnic groups) and inversely associated with HDL-C (p < 0.05 in some, but not all, of the populations). The association of lipids with 2-h plasma glucose (2hPG) followed a similar pattern as that for the FPG, except that an inverse relationship between HDL-C and glucose was more commonly observed for 2hPG than for FPG among different ethnic groups. CONCLUSIONS: Hyperglycaemia is associated with adverse lipid profiles in Asians without a prior history of diabetes. The 2hPG appears to be more closely associated with lipid profiles than does FPG. When assessing the risk of cardiovascular disease, the association of the dyslipidaemia with intermediate hyperglycaemia needs to be considered.

- Background Age is associated with both impaired glucose and insulin metabolism. To what extent the age-related changes in insulin resistance (IR) and β-cell function contribute to the increase in prevalence of impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) is less known, and this is investigated in this study. Methods This study included 6610 men and 7664 women of different ethnic groups aged 30-69 years. IR and β-cell function were examined by the homeostasis model assessment of insulin resistance (HOMA-IR) and homeostasis model assessment of β-cell function (HOMA-B). Odds ratios (ORs) and 95% confidence intervals (95% CIs) were estimated using logistic regression analysis adjusting for body mass index and study. Results In Chinese men, the ORs (95% CIs) for IFG were 2.69 (1.70, 4.26), 2.51 (1.49, 4.21) and 2.89 (1.68, 4.97), respectively, in age groups of 40–49, 50–59 and 60–69 years compared with 30–39 years (p < 0.001 for trend); the corresponding figures for IGT were 1.73 (1.25, 2.38), 2.54 (1.78, 3.63) and 3.57 (2.46, 5.19) (p < 0.001 for trend). Similar trends for IGT were observed also in Chinese women and other ethnic groups, but not for IFG in Mauritius Indian and Creole men. Adjustment for HOMA-IR and HOMA-B reduced the ORs in all age groups of all ethnicities for both IFG and IGT, but the risk gradient between age groups remained particularly for the IGT. Conclusions The age-related increase in glucose intolerance may not be fully explained by the defect in HOMA-IR and HOMA-B. As HOMA-IR and HOMA-B are only surrogate measures of insulin sensitivity and insulin secretion, the results need to be further investigated
