Using multi-trajectory modeling on 4,464 Chinese adults from 1997 to 2018, four distinct cereal-intake patterns were identified, with the group characterized by high white rice intake without other grains showing a higher subsequent risk of type 2 diabetes compared to the balanced cereal intake group. Consumption of other grains was associated with reduced type 2 diabetes risk.
Group-based multi-trajectory modeling identified four distinct cereal-intake patterns: very high rice with low wheat, high rice with moderate wheat, balanced cereal intake, and very low rice with high wheat and moderate other grains. Over 33,659 person-years of follow-up, 422 participants (9.45%) developed T2D. Compared with the balanced cereal intake group, the group with very high white rice intake without other grains had a higher subsequent risk of T2D. Other grain consumption trajectories were associated with lower T2D risk in both sexes. Dose-response analysis indicated potential threshold points for T2D development at daily white rice intakes exceeding 240 grams for men and 280 grams for women.
