To investigate the long term smoking cessation behaviors in a population of Japanese current smokers (CS) and former smokers (FS).
Retrospective survey of Japanese men and women ≥20 years of age who were CS (those who smoked any number of cigarettes at the time of the survey, 24-27 June 2013) or FS (those who had smoked any number of cigarettes in the past but did not consider themselves smokers at the time of the survey). CS/FS were selected from a prescreened source population recruited by online advertisement that was age- and gender-matched, to represent Japanese smokers. Clinical and socio-demographic characteristics and smoking/smoking cessation history were assessed through a web-based questionnaire.
MAIN OUTCOME MEASURES were number of past quit attempts and time to relapse; others included methods used to achieve smoking cessation, and reasons for wanting to quit.
Overall, 1261 Japanese subjects were surveyed (CS, n = 631; FS, n = 630). Nearly half (45.6%) of CS had never attempted to quit smoking. Of those who had attempted to quit smoking, one single quit attempt was the most common for both CS and FS (19.0 vs. 39.0%). Estimated median time to relapse was 105 days (FS and CS combined). Unaided smoking cessation was the most common method both for CS and FS (78.2 vs. 63.4%).
In our survey, >70% of smokers used unaided smoking cessation methods, which may have resulted in a lower success rate. Participants relapsed after a median of 105 days of abstinence (25% within 7 days; the remainder had resumed smoking after 1260 days). As with all surveys, recall bias may have influenced the results. Our observations could be combined with other data in health economic models of smoking cessation to identify appropriate measures to reduce the prevalence of smoking in Japan.
调查日本当前吸烟者（CS）和既往吸烟者（FS）群体的长期戒烟行为。
对年龄≥20岁的日本男性和女性进行回顾性调查，这些人要么是当前吸烟者（在2013年6月24日至27日调查时吸过任何数量香烟者），要么是既往吸烟者（过去吸过任何数量香烟但在调查时不认为自己是吸烟者）。当前吸烟者/既往吸烟者是从通过网络广告招募的经过预先筛选的源人群中选取的，该源人群在年龄和性别上匹配，以代表日本吸烟者。通过基于网络的问卷评估临床和社会人口学特征以及吸烟/戒烟史。
主要观察指标是过去的戒烟尝试次数和复吸时间；其他指标包括实现戒烟所采用的方法以及戒烟意愿。
总体而言，共调查了1261名日本受试者（当前吸烟者，n = 631；既往吸烟者，n = 630）。近一半（45.6%）的当前吸烟者从未尝试过戒烟。在那些尝试过戒烟的人中，单次戒烟尝试在当前吸烟者和既往吸烟者中最为常见（分别为19.0%和39.0%）。估计复吸的中位时间为105天（既往吸烟者和当前吸烟者合并计算）。自主戒烟是当前吸烟者和既往吸烟者最常用的方法（分别为78.2%和63.4%）。
在我们的调查中，超过70%的吸烟者采用自主戒烟方法，这可能导致成功率较低。参与者在戒烟中位时间105天后复吸（25%在7天内复吸；其余在1260天后恢复吸烟）。与所有调查一样，回忆偏倚可能影响了结果。我们的观察结果可与戒烟健康经济模型中的其他数据相结合，以确定降低日本吸烟率的适当措施。
