Long-Term Dynamics of Overweight and Obesity in Chinese Adults and Association with Blood Pressure: Evidence from the China Health and Nutrition Survey.

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.
