Tobacco-attributable deaths contribute significantly to the increased mortality observed among homeless adults aged 50 years or more. Little is known about the epidemiology of tobacco use among older homeless individuals. This longitudinal cohort study examines smoking behaviors and factors associated with smoking cessation among homeless individuals aged 50 years or more.
We recruited a prospective cohort of 350 homeless individuals sampled from the community in Oakland, California. At 6 months follow-up, participants reported their cigarette quit attempts and 30-day abstinence. We used multivariable logistic regression to examine factors associated with making a quit attempt at follow-up, hypothesizing that heavier smokers would be less likely to make a quit attempt.
Of the 272 ever-smokers, 229 (84.2%) were current smokers (quit ratio 15.8). Among current smokers at enrollment who had a follow-up interview at 6 months, 43.6% (n = 71) reported making a quit attempt during the follow-up. Of those who reported making a quit attempt, 14.3% (n = 10) reported 30-day abstinence at follow-up. Among those who had reported making a quit attempt at follow-up, 22.5% had used nicotine replacement therapy (NRT). Staying in shelters (adjusted odds ratio [AOR] = 2.5, 95% confidence interval [CI] = 1.0-5.8) was associated with higher odds of making a quit attempt at follow-up. Higher cigarette consumption was associated with lower odds of making a quit attempt (AOR = 0.9, 95% CI = 0.8-0.9).
In this study of tobacco use in older homeless adults, rates of quit attempts were similar to that observed in the general population, but successful quitting was lower.
The current study is among the first studies to focus specifically on tobacco use and cessation behaviors among older homeless adults. The high prevalence of smoking and the low rates of successful quitting highlight numerous opportunities to intervene to increase quitting rates among this population. Among these, increasing access to smoke-free living environments and identifying effective cessation therapies will be critical to reducing tobacco-related disease burden among older homeless adults.
烟草导致的死亡在50岁及以上无家可归成年人中所观察到的死亡率上升中占很大比例。对于年龄较大的无家可归者的烟草使用流行病学情况知之甚少。这项纵向队列研究调查了50岁及以上无家可归者的吸烟行为以及与戒烟相关的因素。
我们从加利福尼亚州奥克兰市的社区中招募了350名无家可归者组成前瞻性队列。在6个月的随访中,参与者报告了他们的戒烟尝试和30天的戒烟情况。我们使用多变量逻辑回归来研究与随访时进行戒烟尝试相关的因素,假设吸烟量较大者进行戒烟尝试的可能性较小。
在272名曾经吸烟者中,229人(84.2%)为当前吸烟者(戒烟率为15.8%)。在入组时为当前吸烟者且在6个月时接受了随访访谈的人中,43.6%(n = 71)报告在随访期间进行了戒烟尝试。在那些报告进行了戒烟尝试的人中,14.3%(n = 10)报告在随访时实现了30天戒烟。在那些报告在随访时进行了戒烟尝试的人中,22.5%使用了尼古丁替代疗法(NRT)。住在收容所(调整后的优势比[AOR] = 2.5,95%置信区间[CI] = 1.0 - 5.8)与随访时进行戒烟尝试的较高几率相关。较高的香烟消费量与进行戒烟尝试的较低几率相关(AOR = 0.9,95% CI = 0.8 - 0.9)。
在这项针对年龄较大的无家可归成年人的烟草使用研究中,戒烟尝试率与普通人群中观察到的相似,但成功戒烟率较低。
当前的研究是首批专门关注年龄较大的无家可归成年人的烟草使用和戒烟行为的研究之一。吸烟的高流行率和低成功戒烟率凸显了众多干预机会,以提高该人群的戒烟率。其中,增加无烟生活环境的可及性以及确定有效的戒烟疗法对于减轻年龄较大的无家可归成年人的烟草相关疾病负担至关重要。
