PTSD和非PTSD吸烟者戒烟首周复吸的预测因子
2012/12/31
摘要
前言:回顾性研究显示,创伤后应激障碍(PTSD)的吸烟者在戒烟后会在更短的时间内复吸。有必要采用生态瞬时评估(EMA)研究来确认PTSD吸烟者的早期复吸,并对其进行概括,以便采取干预措施。
方法:有PTSD(n = 55)和无PTSD(n = 52)的吸烟者在戒烟前后一周内完成警报提醒的情境和精神变量EMA评估,并在复吸后进行自我EMA评估。在基线状态和戒断日取血,检测脱氢表雄酮(DHEA)和硫酸脱氢表雄酮(DHEA)水平。
结果:PTSD与更短时间内复吸有关(危险比[HR] = 1.677,95% CI: 1.106-2.544)。戒烟自信心增加与较长时间内复吸有关(HR = 0.608, 95% CI: 0.430-0.860)。对参与者实时报告进行的分析显示,PTSD吸烟者更有可能将首次复吸归咎于负面影响(= 5.412, p = 0.020)和创伤提示(Fisher’s精确检验p = 0.003**)。最后,戒烟日DHEA下降与更短时间内复吸有关(HR = 1.009, 95% CI: 1.000-1.018, p <0.05)。
结论:研究结果为PTSD吸烟者短时间内复吸提供了证据,也为PTSD吸烟者早期复吸与创伤提示、负面影响和生理欲望的密切相关性提供了证据。

Abstract
INTRODUCTION: Retrospective research suggests smokers with posttraumatic stress disorder (PTSD) lapse more quickly after their quit date. Ecological momentary assessment (EMA) research is needed to confirm the presence of early smoking lapse in PTSD and form conceptualizations that inform intervention.
METHODS: Smokers with (n = 55) and without (n = 52) PTSD completed alarm-prompted EMA of situational and psychiatric variables the week before and after a quit date, and self-initiated EMA following smoking lapses. Blood samples at baseline and on the quit date allowed assessment of dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA(S)).
RESULTS: PTSD was related to shorter time to lapse (hazard ratio [HR] = 1.677, 95% CI: 1.106-2.544). Increased smoking abstinence self-efficacy was related to longer time to lapse (HR = 0.608, 95% CI: 0.430-0.860). Analyses of participants’ real-time reports revealed that smokers with PTSD were more likely to attribute first-time lapses to negative affect ( = 5.412, p = .020), and trauma reminders (Fisher’s exact p = .003**). Finally, the quit date decrease in DHEA(S) was related to shorter time to lapse (HR = 1.009, 95% CI: 1.000-1.018, p < .05).
CONCLUSIONS: Results provide evidence of shorter time to first smoking lapse in PTSD, and add to evidence that early lapse occasions are more strongly related to trauma reminders, negative affect, and cravings in smokers with PTSD.
