|Abstract: ||Context: Previous studies have identified an obese phenotype without the burden of adiposityassociated cardiometabolic risk factors, although the health effects remain unclear.
Objective: We examined the association between metabolically healthy obesity and risk of cardiovascular disease (CVD) and all-cause mortality.
Design and Setting: This was an observational study with prospective linkage to mortality records in community-dwelling adults from the general population in Scotland and England.
Participants: A total of 22,203 men and women [aged 54.1 (SD 12.7 yr), 45.2% men] without known history of CVD at baseline.
Interventions: Based on blood pressure, high-density lipoprotein-cholesterol, diabetes diagnosis, waist circumference, and low-grade inflammation (C-reactive protein ≥ 3 mg/liter), participants were classified as metabolically healthy (0 or 1 metabolic abnormality) or unhealthy (two or more
metabolic abnormalities). Obesity was defined as a body mass index of 30 kg/m2 or greater.
Main Outcome Measure: Study members were followed up, on average, more than 7.0±3.0 yr for cause-specific mortality. Cox proportional hazards models were used to examine the association of metabolic health/obesity categories with mortality.
Results: Therewere604CVDand1868 all-cause deaths, respectively. Compared with the metabolically healthy nonobese participants, their obese counterparts were not at elevated risk of CVD[hazard ratio
(HR)1.26,95%confidence interval (CI)0.74–2.13],although both non obese (HR1.59,95%CI1.30–1.94) and obese (HR 1.64, 95% CI 1.17–2.30) participants with two or more metabolic abnormalities were at
elevated risk. Metabolically unhealthy obese participants were at elevated risk of all-cause mortality compared with their metabolically healthy obese counterparts (HR 1.72, 95% CI 1.23–2.41).
Conclusion: Metabolically healthy obese participants were not at increased risk of CVD and all cause mortality over 7 yr.|
