Studies in the United States and Europe have found higher smoking prevalence among unemployed job seekers relative to employed workers. While consistent, the extant epidemiologic investigations of smoking and work status have been cross-sectional, leaving it underdetermined whether tobacco use is a cause or effect of unemployment.
To examine differences in reemployment by smoking status in a 12-month period.
DESIGN, SETTING, AND PARTICIPANTS: An observational 2-group study was conducted from September 10, 2013, to August 15, 2015, in employment service settings in the San Francisco Bay Area (California). Participants were 131 daily smokers and 120 nonsmokers, all of whom were unemployed job seekers. Owing to the study's observational design, a propensity score analysis was conducted using inverse probability weighting with trimmed observations. Including covariates of time out of work, age, education, race/ethnicity, and perceived health status as predictors of smoking status.
Reemployment at 12-month follow-up.
Of the 251 study participants, 165 (65.7) were men, with a mean (SD) age of 48 (11) years; 96 participants were white (38.2%), 90 were black (35.9%), 24 were Hispanic (9.6%), 18 were Asian (7.2%), and 23 were multiracial or other race (9.2%); 78 had a college degree (31.1%), 99 were unstably housed (39.4%), 70 lacked reliable transportation (27.9%), 52 had a criminal history (20.7%), and 72 had received prior treatment for alcohol or drug use (28.7%). Smokers consumed a mean (SD) of 13.5 (8.2) cigarettes per day at baseline. At 12-month follow-up (217 participants retained [86.5%]), 60 of 108 nonsmokers (55.6%) were reemployed compared with 29 of 109 smokers (26.6%) (unadjusted risk difference, 0.29; 95% CI, 0.15-0.42). With 6% of analysis sample observations trimmed, the estimated risk difference indicated that nonsmokers were 30% (95% CI, 12%-48%) more likely on average to be reemployed at 1 year relative to smokers. Results of a sensitivity analysis with additional covariates of sex, stable housing, reliable transportation, criminal history, and prior treatment for alcohol or drug use (25.3% of observations trimmed) reduced the difference in employment attributed to smoking status to 24% (95% CI, 7%-39%), which was still a significant difference. Among those reemployed at 1 year, the average hourly wage for smokers was significantly lower (mean [SD], $15.10 [$4.68]) than for nonsmokers (mean [SD], $20.27 [$10.54]; F(1,86) = 6.50, P = .01).
To our knowledge, this is the first study to prospectively track reemployment success by smoking status. Smokers had a lower likelihood of reemployment at 1 year and were paid significantly less than nonsmokers when reemployed. Treatment of tobacco use in unemployment service settings is worth testing for increasing reemployment success and financial well-being.
美国和欧洲的研究发现,相对于在职员工,失业求职者中的吸烟率更高。虽然结果一致,但现有的关于吸烟与工作状态的流行病学调查都是横断面研究,因此吸烟是失业的原因还是结果尚不确定。
研究12个月内按吸烟状况划分的再就业差异。
设计、地点和参与者:2013年9月10日至2015年8月15日在旧金山湾区(加利福尼亚州)的就业服务机构进行了一项观察性两组研究。参与者为131名每日吸烟者和120名不吸烟者,他们均为失业求职者。由于该研究的观察性设计,使用逆概率加权和截尾观察进行倾向得分分析。将失业时间、年龄、教育程度、种族/族裔以及自我感知健康状况作为吸烟状况的预测因素。
12个月随访时的再就业情况。
251名研究参与者中,165名(65.7%)为男性,平均(标准差)年龄为48(11)岁;96名参与者为白人(38.2%),90名是黑人(35.9%),24名是西班牙裔(9.6%),18名是亚洲人(7.2%),23名是多种族或其他种族(9.2%);78人拥有大学学位(31.1%),99人住房不稳定(39.4%),70人缺乏可靠交通工具(27.9%),52人有犯罪史(20.7%),72人曾接受过酒精或药物使用治疗(28.7%)。吸烟者在基线时平均(标准差)每天吸食13.5(8.2)支香烟。在12个月随访时(217名参与者留存[86.5%]),108名不吸烟者中有60名(55.6%)实现再就业,而109名吸烟者中只有29名(26.6%)(未调整风险差异为0.29;95%置信区间为0.15 - 0.42)。在分析样本观察值截尾6%后,估计风险差异表明,相对于吸烟者,不吸烟者在1年时平均再就业可能性高30%(95%置信区间为12% - 48%)。纳入性别、稳定住房、可靠交通工具、犯罪史以及酒精或药物使用既往治疗情况等额外协变量的敏感性分析结果(25.3%的观察值截尾)显示,归因于吸烟状况的就业差异降至24%(95%置信区间为7% - 39%),但仍具有显著差异。在1年时实现再就业的人群中,吸烟者的平均时薪显著低于不吸烟者(平均[标准差],15.10美元[4.68美元]对20.27美元[10.54美元];F(1,86) = 6.50,P = 0.01)。
据我们所知,这是第一项按吸烟状况前瞻性追踪再就业成功率的研究。吸烟者在1年时再就业可能性较低,且再就业时的收入显著低于不吸烟者。在失业服务机构中对烟草使用进行干预,对于提高再就业成功率和改善经济状况值得一试。
