We aim to estimate the prevalence of influenza-like illness (ILI) by occupation and to identify occupations associated with increased ILI prevalence.
Between September 2009 and August 2010, the Centers for Disease Control (CDC) included questions on ILI symptoms on the Behavioral Risk Factor Surveillance System (BRFSS). Washington State collects the occupation of all employed BRFSS respondents. ILI prevalence and prevalence ratios (PR) were calculated by occupational group.
There were 8,758 adult, currently employed, non-military respondents to the Washington BRFSS during the study period. The ILI prevalence for all employed respondents was 6.8% (95% Confidence Interval (95% CI) = 6.1, 7.6). PRs indicated a lower prevalence of ILI in Technicians (PR = 0.4, 95% CI = 0.2, 0.9) and Truck Drivers (PR = 0.2, 95% CI = 0.1, 0.7) and higher prevalence in Janitors and Cleaners (PR = 2.5, 95% CI = 1.3, 4.7) and Secretaries (PR = 2.4, 95% CI = 1.1, 5.4).
Some occupations appear to have higher prevalence of ILI than others. These occupational differences may be explained, in part, by differing levels of social contact with the public or contact with contaminated surfaces at work, or by other occupational factors such as stress or access to health care resources.
我们旨在根据职业估计流感样疾病（ILI）的患病率，并确定与 ILI 患病率增加相关的职业。
2009 年 9 月至 2010 年 8 月期间，疾病控制中心（CDC）在行为风险因素监测系统（BRFSS）上纳入了ILI 症状的问题。华盛顿州收集所有受雇于 BRFSS 的受访者的职业信息。按职业组计算 ILI 的患病率和患病率比（PR）。
在研究期间，有 8758 名成年、在职、非军人的华盛顿 BRFSS 受访者。所有受雇受访者的 ILI 患病率为 6.8%（95%置信区间[95%CI]为 6.1，7.6）。PR 表明，技术员（PR=0.4，95%CI=0.2，0.9）和卡车司机（PR=0.2，95%CI=0.1，0.7）的 ILI 患病率较低，而看门人、清洁工（PR=2.5，95%CI=1.3，4.7）和秘书（PR=2.4，95%CI=1.1，5.4）的 ILI 患病率较高。
某些职业似乎比其他职业的 ILI 患病率更高。这些职业差异可能部分归因于与公众的社交接触程度不同，或者工作中接触受污染表面的程度不同，或者其他职业因素，如压力或获得医疗保健资源的机会不同。
