Abstract
PurposeThe prognostic significance of obesity phenotypes is under debate, and few studies have characterized their transition trajectories. This study examined the natural courses of different phenotypes and their associations with cardiovascular disease risks. MethodsA total of 1827 participants were followed for 14 years and re-evaluated every 4–5 years. Four metabolite BMI phenotypes were determined according to overweight or obesity (BMI ≥ 24 kg/m2) and metabolic health status (≤1 Adult Treatment Panel III criteria, excluding waist circumference). Cardiovascular risks were assessed by evaluating baPWV and hypertension, diabetes and chronic kidney disease (CKD) development. ResultsMore than 20% of participants changed their initial phenotypes within 5 years. One-third of healthy overweight/obese (MHO) individuals became unhealthy, and only 10.6% regressed to a healthy normal weight (MHN) at the end of follow-up. Compared with MHN participants, MHO participants had higher odds of increased baPWV (OR: 1.18, 95% CI, 0.42–3.33) and increased risks of incident hypertension (HR: 1.87, 95% CI, 1.18–2.98) and diabetes (HR: 2.61, 95% CI, 1.35–5.03). Metabolic deterioration during follow-up resulted in an increased risk of baPWV and clinical diseases. ConclusionsThe natural trajectory of metabolite BMI phenotypes is time-varying, and interventions for both healthy and unhealthy overweight/obese individuals should be widely recommended.
