Dai H, Li F, Bragazzi NL, et al. - In general Chinese adults, researchers ascertained if distinct developmental trajectories of BMI would be predictive of diabetes risk. The study sample consisted of 4,519 candidates aged > 18 years who were free of diabetes in 2011 (baseline of the current analysis). Four distinct BMI trajectories were identified according to BMI range and changing pattern over time during 2011–2016: “low” (19.6%), “moderate” (33.4%), “moderate-high” (33.4%) and “high” (13.6%). In 2016, a total of 168 new-onset cases of diabetes were confirmed. According to this longitudinal study, distinct BMI trajectories, even identified using just four or three annual BMI tests, were significantly linked to new-onset diabetes. Over time monitoring of BMI trajectories could provide an important approach for identifying subpopulations with a higher risk of diabetes in general Chinese adults.
