許多人吸煙是為了緩解精神壓力,，但英國一項最新研究說,，這種認識是錯誤的，戒煙而不是吸煙才有助降低焦慮感,。
英國倫敦國王學(xué)院等機構(gòu)研究人員在新一期《英國精神病學(xué)期刊》上報告說,，對491名參與戒煙計劃的吸煙者進行了考察，他們最初吸煙的原因,，有的是“純?yōu)閵蕵?rdquo;,，還有的是“應(yīng)對壓力”。他們在為期6個月的計劃開始前和結(jié)束后都接受了心理測試,，結(jié)果顯示,，所有成功戒煙者的焦慮感都降低，特別是那些為了“應(yīng)對壓力”而吸煙的人群,，焦慮感下降更明顯,。
與此相對的是，那些在戒煙一段時間后又恢復(fù)吸煙的人,，焦慮感又上升了,，這種情況在因“應(yīng)對壓力”而吸煙的人群中比較明顯。但在“純?yōu)閵蕵?rdquo;而吸煙的人群中,，沒有出現(xiàn)這種因戒煙不成功而焦慮感上升的情況,。(生物谷Bioon.com)

Change in anxiety following successful and unsuccessful attempts at smoking cessation: cohort study

Background Despite a lack of empirical evidence, many smokers and health professionals believe that tobacco smoking reduces anxiety, which may deter smoking cessation. Aims The study aim was to assess whether successful smoking cessation or relapse to smoking after a quit attempt are associated with changes in anxiety. Method A total of 491 smokers attending National Health Service smoking cessation clinics in England were followed up 6 months after enrolment in a trial of pharmacogenetic tailoring of nicotine replacement therapy (ISRCTN14352545). Results There was a points difference of 11.8 (95% CI 7.7–16.0) in anxiety score 6 months after cessation between people who relapsed to smoking and people who attained abstinence. This reflected a three-point increase in anxiety from baseline for participants who relapsed and a nine-point decrease for participants who abstained. The increase in anxiety in those who relapsed was largest for those with a current diagnosis of psychiatric disorder and whose main reason for smoking was to cope with stress. The decrease in anxiety on abstinence was larger for these groups also. Conclusions People who achieve abstinence experience a marked reduction in anxiety whereas those who fail to quit experience a modest increase in the long term. These data contradict the assumption that smoking is a stress reliever, but suggest that failure of a quit attempt may generate anxiety.
