Abstract:
Objective: To investigate the association between metabolically healthy obesity and the incident risk of stroke in people aged ≥40 years from rural areas of Henan Province. Methods: During 2007 to 2008, 20 194 residents aged ≥18 years were selected for baseline examination by random cluster sampling and 17 265 participants were followed up during 2013 to 2014. According to the aim of current study, a total of 11 864 eligible subjects were included in this post-hoc analysis. Depending on body mass index and metabolic status, subjects were divided into four groups: metabolically healthy normal weight, metabolically healthy obesity, metabolically abnormal normal weight and metabolically abnormal obesity. Multivariate logistic regression model was used to analyze the relationship between metabolically healthy obesity and the risk of stroke. Results: The median (Q1, Q3) age of study participants was 54(46, 61) years, and 4 526 participants were men. During the mean follow-up of 6 years, the cumulative incidence of stroke was 7.16%. The incidence of stroke in metabolically healthy normal weight, metabolically healthy obesity, metabolically abnormal normal weight, and metabolically abnormal obesity were 3.73%, 4.61%, 8.99% and 9.38%, respectively (χ²=117.458, P<0.001). After adjusting possible confounding factors, compared with metabolically healthy normal weight, the risk of stroke was significantly increased in the metabolically healthy obesity group, metabolically abnormal normal weight group and metabolically abnormal obesity group with the odds ratio (OR) and 95% confidence interval (CI) of 1.52(1.10-2.12), 2.11(1.61-2.77) and 2.78(2.18-3.55), respectively. Stratified analysis showed that the risk of stroke was significantly higher in metabolically healthy obesity people aged 40-59 years compared with metabolically healthy normal weight group (OR=2.12, 95%CI: 1.36-3.30). Conclusion: Metabolically healthy obesity, metabolically abnormal normal weight and metabolically abnormal obesity are positively associated with the risk of stroke.
