Association between central obesity and cardiometabolic diseases or cardiometabolic comorbidity in residents aged 35−75 years in Inner Mongolia

  Objective  To analyze the association between central obesity and cardiometabolic diseases or cardiometabolic comorbidity in residents aged 35–75 years in Inner Mongolia autonomous region.

  Methods  Residents aged 35–75 years recruited in “Early Screening and Comprehensive Intervention in Population at High Risk for Cardiovascular Diseases” in Inner Mongolia from September 2015 to June 2017 were selected for the study. Statistical analysis was performed by using software SPSS 25.0 and GraphPad Prism 5, mainly statistical description, χ² test and logistic regression analysis, to understand impact of central obesity on cardiometabolic diseases (hypertension, diabetes, dyslipidemia) and cardiometabolic comorbidity.

  Results  The prevalence rate of central obesity was 66.5% (95%CI: 66.2%–66.7%), and the standardized rate was 64.6% in residents aged 35–75 years in Inner Mongolia. The proportions of persons with 0, 1, 2 and 3 cardiometabolic diseases were 28.8%, 40.5%, 23.8% and 6.9%, respectively. The results of logistic regression analysis showed that the risk for hypertension, diabetes, dyslipidemia and cardiometabolic comorbidity were 1.873 times and 3.093 times, 1.876 times and 2.764 times, 2.227 times and 3.412 times, 2.526 times and 4.419 times higher in people with mild central obesity and severe central obesity than in those without central obesity (all P<0.001).

  Conclusions  Central obesity is a serious health problem in Inner Mongolia, and it is a risk factor for cardiometabolic diseases or cardiometabolic comorbidity, Therefore, we should strengthen the early screening of central obesity and conduct intervention.
