Although the association between smoking status and poorer mental health has been well documented, the association between quit status and psychological distress is less clear. The aim of the present study is to investigate the association of smoking status and quit status with psychological distress.
Data for this study is from a single year of the Survey of Families, Income and Employment (SoFIE) conducted in New Zealand (2004/05) (n = 18,525 respondents). Smoking status and quit status were treated as exposure variables, and psychological distress (Kessler-10) was treated as the outcome variable. Logistic regression analyses were performed to determine the association of smoking with psychological distress in the whole adult population and quit status with psychological distress in the ex- and current-smoking population.
Current smokers had higher rates of high and very high psychological distress compared to never smokers (adjusted odds ratio (aOR) = 1.45; 95% CI: 1.24-1.69). Unsuccessful quitters had much higher levels of high to very high levels of psychological distress (16%) than any other group. Moreover, compared to long-term ex-smokers, unsuccessful quitters had a much higher odds of high to very high levels of psychological distress (aOR = 1.73; 95% CI: 1.36-2.21).
These findings suggest that the significant association between smoking and psychological distress might be partly explained by increased levels of psychological distress among current smokers who made a quit attempt in the last year. This issue needs further study as it has implications for optimising the design of quitting support.
尽管吸烟状况与较差的心理健康之间存在关联已得到充分证实，但戒烟状况与心理困扰之间的关联则不太明确。本研究旨在调查吸烟状况和戒烟状况与心理困扰之间的关联。
本研究的数据来自新西兰进行的家庭收入和就业调查（SoFIE）（2004/05 年）（n=18525 名受访者）的单一年份。吸烟状况和戒烟状况被视为暴露变量，心理困扰（Kessler-10）被视为结果变量。进行逻辑回归分析，以确定吸烟与所有成年人群体中心理困扰的关联，以及戒烟状况与曾经和现在吸烟人群中心理困扰的关联。
与从不吸烟者相比，当前吸烟者出现高和极高心理困扰的比率更高（调整后的优势比（aOR）=1.45；95%置信区间：1.24-1.69）。未成功戒烟者的高至极高水平心理困扰（16%）比任何其他组别都高得多。此外，与长期戒烟者相比，未成功戒烟者出现高至极高水平心理困扰的几率高得多（aOR=1.73；95%置信区间：1.36-2.21）。
这些发现表明，吸烟与心理困扰之间的显著关联可能部分归因于过去一年中尝试戒烟的当前吸烟者心理困扰程度增加。这个问题需要进一步研究，因为这对优化戒烟支持的设计具有影响。
