目的 调查我国北方海域部分海员的体重指数 (BMI)及其与血压的关系。方法 对 4 12 0名北方海域海员按统一标准测量血压 ,同时测量身高、体重 ,计算体重指数。结果 (1)北方海域海员BMI(2 2 .2 5± 2 .2 9) ,显著高于 1991年全国抽样调查男性 BMI2 1.4 (P<0 .0 1)。 (2 ) BMI均值与血压均值呈正相关 (与收缩压 r=0 .95 9,P<0 .0 0 1;与舒张压 r=0 .937,P<0 .0 0 1)。 (3) BMI均值与高血压患病率呈正相关 (r=0 .936 ,P<0 .0 0 1)。 (4)超重者 (BMI≥ 2 5 )高血压患病率 (2 4 .2 1% )显著高于非超重者 (8.84 % ) (P<0 .0 0 1)。结论 北方海域海员 BMI显著偏高 ,且与高血压患病率呈正相关 ,应予以重视
Objective To investigate the relationship between body mass index (BMI) and blood pressure in some seafarers in northern China. Methods 4 12 0 seafarers in the northern sea area were measured blood pressure according to a uniform standard, meanwhile height and weight were measured, body mass index (BMI) was calculated. Results (1) The BMI of seafarers in the north sea area was significantly higher than that of the national sample survey in 1991 (2.225 ± 2.29) (P <0.01). (2) The mean of BMI was positively correlated with the mean of blood pressure (systolic pressure, r = 0.959, P <0.01; and diastolic pressure, r = 0.937, P <0.01). (3) The mean of BMI was positively correlated with the prevalence of hypertension (r = 0.936, P <0.01). (4) Overweight (BMI≥25) The prevalence of hypertension was significantly higher (24.21%) than that of non-overweight (8.84%) (P <0.01). Conclusion The BMI of seafarers in northern sea area is significantly higher than that of hypertension, and it is positively correlated with the prevalence of hypertension, which should be paid attention to
