Dietary patterns, dietary intakes and the risk of type 2 diabetes: results from the Hefei Nutrition and Health Study

摘要

A total of 1776 Chinese adults, aged 40-60 years, had been recruited to participate in the Hefei Nutrition and Health Study started in 2012. Three major dietary patterns were identified, "High-salt and high-fat", "Traditional Chinese" and "Western" dietary patterns. After adjusting for potential confounders, there is no significant difference in the effect of different dietary pattern quintiles on the risk of type 2 diabetes (T2D). However, compared with lowest quintile intakes, the adjusted odds ratio of T2D for highest quintile intakes of bread and noodle, rice noodle and coarse grain were 2.45 (95% CI: 1.17, 5.12), 0.34 (95% CI: 0.17, 0.92), 0.27 (95% CI: 0.14, 0.51), with corresponding p trend being .002, .375, .003, respectively. Our study suggests that high intakes of bread and noodle are significantly associated with increased risk of T2D, while high intakes of rice noodle and coarse grain are remarkably correlated with decreased risk of T2D.
