Background Overweight and obesity represent critical modifiable determinants in the prevention of cardiometabolic disease (CMD). However, the long‐term impact of prior overweight/obesity on the risk of CMD in later life remains unclear. We aimed to investigate the association between longitudinal transition of body mass index (BMI) status and incident CMD. Methods and Results This prospective cohort study included 57 493 CMD‐free Chinese adults from the Kailuan Study. BMI change patterns were categorized according to the BMI measurements obtained during the 2006 and 2012 surveys. The primary end point was a composite of myocardial infarction, stroke, and type 2 diabetes. Cox regression models were used to evaluate the associations of transitions in BMI with overall CMD events and subtypes, with covariates selected on the basis of the directed acyclic graph. During a median follow‐up of 7.62 years, 8412 participants developed CMD. After considering potential confounders, weight gain pattern (hazard ratio [HR], 1.34 [95% CI, 1.23–1.46]), stable overweight/obesity (HR, 2.12 [95% CI, 2.00–2.24]), and past overweight/obesity (HR, 1.73 [95% CI, 1.59–1.89]) were associated with the incidence of CMD. Similar results were observed in cardiometabolic multimorbidity, cardiovascular disease, and type 2 diabetes. Additionally, triglyceride and systolic blood pressure explained 8.05% (95% CI, 5.87–10.22) and 12.10% (95% CI, 9.19–15.02) of the association between past overweight/obesity and incident CMD, respectively. Conclusions A history of overweight/obesity was associated with an increased risk of CMD, even in the absence of current BMI abnormalities. These findings emphasize the necessity for future public health guidelines to include preventive interventions for CMD in individuals with past overweight/obesity.
