Abstract:
      Objective To investigate the relationship of blood pressure with body mass index (BMI) and waist circumference (WC) in the elderly. Methods A total of 449 retired cadres who receiving physical examination routinely in our department from January 2010 to December 2014 were enrolled in this study. They were divided into 3 groups, that is, normal BMI, overweight and obesity groups according to their BMI results. They were also assigned into normal WC and abdominal obesity groups based on their WC values. Their medical data and blood pressure were recorded and analyzed. Results There were no significant differences in being overweight, obesity and central obesity between males and females (P>0.05). The patients from the overweight and obesity groups had significantly higher 24-hour mean systolic blood pressure (SBP24h), 24-hour mean diastolic blood pressure (DBP24h) and rate of hypertension than those from the normal BMI group, so were the central obesity patients than those with normal WC. Correlation analysis confirmed that BMI and WC were positively correlated with SBP24h and DBP24h. Conclusion BMI and WC are positively correlated with blood pressure in the elderly, suggesting the importance of body mass control in the prevention of hypertension.
