Abstract: Background　The prevalence of chronic diseases in cruise drivers is significantly higher due to long working hours，high mental stress，irregular diet and sedentary lifestyle.There is no research on online car-hailing drivers in terms of chronic diseases and other health problems，although other cruise drivers have been studied.Moreover，health conditions of online car-hailing drivers have not drawn enough attention from the government and the industry.We studied the prevalence and influencing factors of hypertension in this group，and put forward corresponding health improvement suggestions.Objective　To investigate the prevalence and influencing factors of hypertension in online car-hailing drivers，putting forward recommendations for improving the health management of this group.Methods　From September to November 2017，we conducted this online survey with an electronic questionnaire developed based on the www.wjx.cn platform among a random sample of online car-hailing drivers with registered accounts in accordance with the principle that one registered account of the driver could only fill out one questionnaire.The survey covered demographic，socioeconomic and work-related characteristics，health behaviors，prevalence of hypertension，healthcare awareness and healthcare needs.Results　A total of 9 003 cases participated in the survey，and 8 990 of them（99.86%） returned responsive questionnaires.The overall prevalence of hypertension was 8.64%（777/8 990）.Logistic regression analysis showed that 35-54 years old 〔OR=0.582，95%CI（0.408，0.829） 〕，18-34 years old 〔OR=0.276，95%CI（0.188，0.407） 〕，working in central China 〔OR=1.523，95%CI（1.199，1.953） 〕，working in eastern China 〔OR=1.398，95%CI（1.140，1.716） 〕，at least three years of full-time drivers experience 〔OR=1.218，95%CI （1.044，1.422）〕，driving period at day and night，not fixed〔OR=0.847，95%CI（0.718，0.999） 〕，exercise time outside of the car ≥5 min〔OR=0.784，95%CI（0.670，0.917） 〕，daily sleep time ≥6 h 〔OR=0.806，95%CI（0.681，0.954） 〕 ，drinking alcohol three or more days each week〔OR=1.383，95%CI（1.112，1.719） 〕，slightly underweight〔OR=2.669，95%CI（1.799，3.961） 〕，and obese〔OR=3.153，95%CI（2.612，3.806） 〕 were associated with the prevalence of hypertension among car-hailing drivers（P<0.05）.Compared with those without hypertension，hypertensive drivers showed higher percentages of having a physical examination within 1 year and having the latest blood pressure measurement within 1 month（P<0.05）.Moreover，they demonstrated higher percentages of obtaining health knowledge via using mobile phone，watching TV，and listening to the radio but showed lower percentages of obtaining such knowledge from the Internet and other ways（P<0.05）.Furthermore，they had higher percentages of obtaining information about hypertension risk prevention，symptom diagnosis，therapeutic effect and hospital specialty care（P<0.05）.Conclusion　It is necessary to strengthen the health management in online car-hailing drivers，in particular those who aged 55 or over，work in central and eastern China，work as a full-time driver for at least 3 years，drive in a fixed time period in the day or at night regularly，have no the habit of exercising outside of the car，sleep less than 6 hours per day，drink alcohol three or more days per week，and are slightly underweight or obese.

摘要： 背景　一般出租车司机受工作时间长、精神高度紧张、饮食不规律、静坐时间长等影响，慢性病患病率明显高于一般人群。相较于一般出租车司机的相关研究，国内外对于网约车司机慢性病等健康状况的相关研究目前尚未开展，网约车司机的健康状况也未引 起政府和行业的足够重视。因此，本研究从网约车司机的高血压患病状况入手，分析其健康影响因素，为改善网约车司机健康状况提出建议。目的　通过对网约车司机的高血压患病现状和影响因素的调查，为网约车司机的健康管理提出对策建议。方法　2017年9—11月， 通过问卷星制作电子表格，向全国网约车司机账号随机发放调查问卷，同一账号只能填写一次问卷。调查问卷内容包括人口学特征、社会经济学特征、工作特征、健康行为、高血压患病情况、健康意识与健康需求。结果　共回收问卷9 003份，有效问卷8 990份，回收有 效率为99.86%。8 990例研究对象中，高血压777例（8.64%）。多因素Logistic回归分析结果显示，年龄35~54岁〔OR=0.582，95%CI（0.408，0.829）〕和18~34岁〔OR=0.276，95%CI（0.188，0.407）〕，中部地区〔OR=1.523，95%CI（1.199，1.953）〕和东部地区〔OR=1.398，95%CI（1.140，1.716）〕，专职司机年数≥3年〔OR=1.218，95%CI（1.044，1.422）〕，开车时间段为白天和晚上、不固定〔OR=0.847，95%CI（0.718，0.999）〕，每天下车活动时长≥5 min〔OR=0.784，95%CI（0.670，0.917）〕，每天睡眠时长≥6 h〔OR=0.806，95%CI（0.681，0.954）〕，饮酒频率≥3 d/周〔OR=1.383，95%CI（1.112，1.719）〕、肥胖程度（过轻）〔OR=2.669，95%CI（1.799，3.961）〕和肥胖程度（肥胖）〔OR=3.153，95%CI（2.612，3.806）〕是网约车司机高血压患病的影响因素（P<0.05）。高血压组1年内做过健康体检比例、最近一次测血压时间为1个月内比例均高于非高血压组（P<0.05）。高血压组从手机、电视、广播处获取健康知识所占比例高于非高血压组，从互联网、其他方面获取健康知识所占比例低于非高血压组（P<0.05）；高血压组获取风险预 防、症状诊断、治疗效果、医院专科的知识所占比例均高于非高血压组（P<0.05）。结论　需要加强对网约车司机的健康管理，尤其是年龄≥55岁、中东部地区、从事专职司机年数≥3年、白天或晚上开车时间段固定、没有下车活动习惯、每天睡眠时长<6 h、饮酒频率≥ 3 d/周、健康程度为偏瘦和肥胖的网约车司机是高血压高风险人群。
