Abstract：Objective To explore the blood pressure level of Beijing bus drivers and the relative risk factors.Methods Cluster sampling method was used to investigate the bus drivers' blood pressure.SPSS 19.0 software was applied to analyze the data.Results The detective rate of hypertension was 28.6％ (198/693) among bus drivers,which was higher than that among the non-bus drivers[13.7％ (93/678),P ＜0.05].The detective rate of hypertension among bus drivers was 15.1％ (24/159) between 26 and 35 years old,26.6％ (75/282) between 36 and 45 years old,39.3％ (99/254) between 46 and 55 years old; the detective rate of hypertension in control subjects was 3.9％ (6/152) between 26 to 35 years old,13.6％ (36/264) between 36 to 45 years old,19.5 ％ (51/262) between 46 to 55 years old.There were significant differences among different ages (P ＜ 0.05).In the same age stage,the detective rates of hypertension of bus drivers were higher than those of non-bus driversand there was asignificant difference(P ＜ 0.05).The average systolic pressure,diastolic pressure and average artery pressure of bus drivers were higher than those of non-bus drivers [(122 ± 13) mmHg vs (108 ± 11) mmHg,(73 ± 8) mmHg vs (64 ± 8) mmHg,(89 ± 9) mmHg vs (75 ± 8) mmHg,allP ＜ 0.05].The prevalence rate of bus drivers with body mass index(BMI) ＞ 25 kg/m2 was higher than that of bus drivers with BMI ≤25 kg/m2 ; prevalence rate of bus drivers with smoking history was higher than that of bus drivers with non-smoking history and there were significant differences (all P ＜ 0.05).Conclusions The levels of blood pressure in bus drivers are obviously increased.The prevalence rate of bus drivers with obesity and smoking is high.
