Study on the status and influencing factors of hypertension in civil aviation pilots / 中国职业医学

ABSTRACT

OBJECTIVE: To investigate the incidence and influencing factors of hypertension among civil aviation pilots. METHODS: A total of 1 169 civil aviation pilots in Northern China were selected into the study by the method of convenient sampling. Physical examination, laboratory test and questionnaire survey were conducted. RESULTS: The prevalence of hypertension in Northern China was 4.7%(55/1 169). Multivariate regression analysis showed that the relative risk factors ranking from high to low were, age over 30 years [odds ratio(OR)=6.81, 95% confidence interval(95%CI) 3.57-12.98)], total flight hours over 1 000 hours(OR=4.24, 95%CI 2.14-8.41), flight hours over 500 hours in the past year(OR=2.91, 95%CI 1.57-5.40), obesity(OR=2.50, 95%CI 1.08-5.81), fasting blood glucose(OR=2.24, 95%CI 1.21-4.13), and frequent long-distance flight(OR=2.38, 95%CI 1.24-4.58). These factors were the risk factors of hypertension in civil aviation pilots(P<0.05). CONCLUSION: Age, total flight hours, flight hours in the past year, obesity, fasting blood glucose, frequent long-distance flight are related to the prevalence of hypertension in civil aviation pilots.
