RESUMEN
Objective To investigate the current situation of treatment and control of hypertension among the elderly in Jiang’an District of Wuhan, and to analyze the relationship between body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR) and the treatment and control of hypertension. Methods A random sampling method was used to recruit 17,749 hypertension patients aged 65 and above who participated in free physical examinations for the elderly in Jiangan District. Relevant information was collected through questionnaire surveys and physical examinations in 2018. Logistic regression analysis was conducted to analyze the correlation between BMI, WC, WHtR and the treatment and control rate of hypertension. Results Among all elderly hypertension patients included in this study, 12,379 (69.74%) reported the treatment of hypertension, of which 6,055(48.91%) had their high blood pressure under control. After adjusting factors such as gender, age, and education level, etc., obesity (OR=1.698), central obesity (OR=1.445), and abnormal WHtR (OR=1.421) were the protective factors of the treatment of hypertension. Overweight (OR=0.843), obesity (OR=0.762) and high WHtR（OR=0.889）reduced the control rate of hypertension. There was no significant relationship between abdominal obesity and blood pressure control. Conclusion Overweight，obesity and high WHtR are the risk factors of hypertension control in the elderly. Weight management can therefore be a takeaway as a key intervention measure for hypertension management in the elderly.
