Abstract:
OBJECTIVETo assess the relationship between body mass index (BMI), waist circumference (WC) and blood pressure (BP) including hypertension.
METHODSA total of 30 003 participants aged 35 - 59 from different parts of China were surveyed for cardiovascular disease risk factors in two independent cross-sectional studies that were carried out in 1992 - 1994 and in 1998. Data were pooled to analyze the levels of BP and rates of hypertension with different levels of BMI and WC.
RESULTSThe level of BP and rate of hypertension were significantly increasing with rising of WC among the majority of BMI groups (P value for trend < 0.05) and significantly increasing with rising of BMI in all WC groups (P value for trend < 0.05). The age adjusted hypertension rate with BMI < 24.0 kg/m(2) and WC < 85/80 cm (men/women), BMI < 24.0 kg/m(2) and WC >or= 85/80 cm (M/W), BMI 24.0 - 27.9 kg/m(2) and WC < 85/80 cm (M/W), BMI 24.0 - 27.9 kg/m(2) and WC >or= 85/80 cm (M/W), BMI >or= 28 kg/m(2) and WC >or= 85/80 cm (M/W) were 16.5%, 29.8%, 29.6%, 39.2% and 57.5% for men and 14.1%, 20.6%, 24.7%, 30.3% and 43.3% for women, respectively.
CONCLUSIONIndependent influence of BMI or WC on BP was noticed. Keeping BMI and WC at normal level might effectively prevent the occurrence of hypertension.
