Abstract

Background: Overweight and obesity have turned into a substantial public health crisis worldwide. We aimed to estimate the prevalence and risk factors of overweight and obesity.

Method: Data collected from the China Health and Nutrition Survey (CHNS) from 1993 to 2015, including 75,559 adults. We used linear-by-linear trend tests, logistic models, and Cox regression models to test the relationship between the prevalence of overweight and obesity and blood pressure.

Results: From 1993 to 2015, the prevalence of overweight and obesity increased from 34.94% to 69.63%, and the prevalence of females was higher than that of males. Cox regression analysis showed that systolic pressure (SBP) <140 and diastolic pressure (DBP) <90 was associated with a lower prevalence in participants. Compared by both age and gender, SBP and DBP were risk factors for the prevalence of overweight and obesity.

Conclusion: Higher DBP and SBP were associated with a higher risk of overweight and obesity. When developing blood pressure control strategies, comprehensive consideration should be given to population demographics, with an emphasis on promoting individualized intervention approaches.
