Multiple Trajectories of Cereal Consumption and Their Associations with Type 2 Diabetes in Chinese Adults — China, 1997–2018

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Consuming refined grains, specifically white rice, elevates the risk of developing type 2 diabetes (T2D). Conversely, incorporating whole grains into the diet is linked to a reduced risk. WHAT IS ADDED BY THIS REPORT? This study employed a novel multi-trajectory modeling technique to account for the intercorrelations among various cereal consumption patterns. Four distinct multi-trajectory groups of cereal intake, identified from 1997 to 2018 within the Chinese population, were associated with varying levels of T2D risk. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? This research investigates the implications of evolving cereal consumption patterns on T2D in nondiabetic adults. This study delineates unique trajectories linked with cereal intake patterns, thereby providing a robust foundation for policymakers to craft initiatives to prevent T2D among adults in China.
