title: Body composition as a predictor of blood pressure in three communities in Guangdong province, China.
abstract: The aim of this study was to compare mean blood pressure (BP), anthropometric and body compositional measurements in three Chinese communities and to examine relationships between BP and body composition in these communities. A total of 935 adult (aged >= 25 years) men and women were randomly sampled from three communities (Chauzhou County speaking Teochew, Meixian County speaking Hakka, and Xinhui speaking Cantonese) in Guangdong Province, China. Self-administered questionnaires about food habits, lifestyle and health status were completed. Body weight, stature, waist and hip circumferences and systolic and diastolic blood pressures were measured. Body mass index, waist to hip ratio, fat free mass, total body fat mass and the percentage body fat were calculated to assess body composition. No significant differences were found in stature, body mass index, umbilical circumference, hip circumference, fat free mass, percentage body fat and defined hypertension between the three communities. However, the waist to hip ratio was lower in Chauzhou men than Meixian women. The mean BPs were different between the communities and mean blood pressure was the highest in the Chauzhou community. Intra-community non-parametric relations between BP and body composition were found mostly in men with increased total and abdominal fatness positively related to BP. The relationships of the aggregate communities with blood pressure were found consistent with those for intra-community analyses, although the body fatness-blood pressure relationship was then evident without exception. Anthropometrically assessed body composition predicts BP in Chinese men, but to a lesser extent, in Chinese women in Guangdong Province, China.
