Abstract

Background: The benefit of weight loss for reducing cardiovascular disease (CVD) risk in metabolically healthy obese people is unknown. Objectives: We evaluated the association between weight change and incident subclinical carotid atherosclerosis (SCA) in metabolically healthy but overweight or obese subjects. Methods: Cohort study of 3117 metabolically healthy overweight or obese adults who did not have any metabolic syndrome components or insulin resistance at baseline. SCA was assessed using carotid artery ultrasonography. The study outcome was the development of incident SCA among participants free of the disease at baseline. Results: During 12 248 person-years of follow-up (median 3.42 years), 747 participants developed SCA. The proportions of participants with no reduction or increased weight, reduction in weight from 0.1% to 4.9%, and reduction in weight ≥ 5% during follow-up were 47.0%, 44.4%, and 8.6%, respectively. The fully-adjusted hazard ratios (HRs) for incident SCA in participants with a reduction in weight of 0.1% to 4.9% and ≥ 5% compared with those with no reduction or increased weight were 0.84 (95% CI, 0.72-0.98) and 0.66 (95% CI, 0.50-0.87), respectively. Conclusions: In a large cohort study of metabolically healthy but overweight or obese adult men and women, weight reduction was associated with a lower incidence of SCA. Our findings suggest that metabolically healthy overweight or obese subjects may benefit from weight reduction in terms of CVD risk.
