Abstract: Objective To compare the predictive value of different obesity indicators for hypertension in different gender and age. Methods The study was based on the community health survey in 2018 in Longhua District, Shenzhen. After standardized transformation of five obesity indicators, including body mass index （BMI）, waist circumference （WC）, waist height ratio （WHtR）, waist-to-hip ratio （WHR） and body obesity index （BAI）, the correlation between the obesity indicators and hypertension was compared according to the OR values obtained from the Logistic regression analysis. The predictive value of each obesity indicator for hypertension was estimated by the area under the receiver operating characteristic curve （ROC）. Furthermore, the ability of each obesity indicatorin predicting hypertension wascomprehensively evaluated. Results After adjusting for confounding factors, WC and WHtR were more strongly associated with hypertension in both genders than other obesity indicators. The predictive power of WHtR for hypertension in male and female were stronger than other obesity indicators,the AUC and 95% CI were 0.694 （0.659-0.728） and 0.763 （0.732-0.794）,the cut-off values were 0.51 and 0.50, respectively. Female had higher AUC of hypertension than men, and each obesity indicator had higher predictive value for female hypertension. After stratified by age in both genders, the predictive value of obesity indicators except WHR in the young male group （18-44 years old） was higher than that in the middle-aged group （45-59 years old） and the elderly group （60-80 years old）. In female, the predictive value of obesity indicators for hypertension decreased with age, followed by young group > middle-aged group >elderly group. Conclusion After considering both gender and age, the predictive power of WHtR in central obesity index for hypertension is better than WC, BMI, WHR and BAI.
