Predictors of long-term smoking cessation among smokers enrolled in a university smoking cessation program

Abstract

Many lifelong smokers establish smoking habits during young adulthood. A university can be an effective setting for early smoking cessation. We evaluated long-term predictors of smoking cessation among smokers in a university setting. We longitudinally followed a cohort of smokers enrolled in a university smoking cessation program in Seoul, South Korea. Sociodemographic factors, smoking-related variables, and changes in smoking habits were assessed during 6-week visit sessions and follow-up telephone interviews conducted 1 year or more later. A total of 205 participants were followed up (mean follow-up duration: 27.1 months). Cessation rates were 47.3% at the end of the visit sessions and 28.8% at follow-up. The long-term persistent smoking rate was significantly higher among individuals with peers who smoked (odds ratio [OR] = 8.64; 95% confidence interval [CI] = 1.75, 42.80), with family members who smoked (OR = 3.28; 95% CI = 1.20, 9.00), and who smoked 10 to 19 cigarettes/day (OR = 4.83; 95% CI = 1.49, 15.69). Conversely, persistent smoking was less likely among those who attended the program regularly (OR = 0.84 per visit; 95% CI = 0.72, 0.99) and attempted quitting more frequently (OR = 0.93 per attempt; 95% CI = 0.87, 0.99). Use of smoking cessation medications (varenicline or bupropion) was not significantly associated with long-term quitting (OR = 0.71; 95% CI = 0.26, 1.93). Peer influences were the strongest predictors of failure in long-term cessation among smokers who attempted to quit. Similarly, the existence of smokers in the family was negatively associated with successful quitting. Regular attendance at a smoking cessation program and a high number of attempts to quit were positively associated with successful quitting. Targeting peer and family smoking groups together rather than targeting individual smokers alone, implementing active cessation programs encouraging regular attendance, and providing comprehensive antismoking environments might be effective strategies in a university setting.

Peer support for smoking cessation: a protocol of systematic review and meta-analysis

“… Tobacco abstinence rate Short-term abstinence: < 3 months after quitting day [ 16 ] Medium-term abstinence: > 3 months and < 12 months after quitting day Long-term abstinence: > 12 months after quitting day [ 17 ] …”

“…An I 2 value of > 50% will be considered an indication of substantial heterogeneity [ 23 ]. Contour enhanced funnel plot will be used to detect any publication bias if more than 10 studies are included in this analysis [ 17 ].…”

A Qualitative Study Exploring Smoking Cessation Experiences of People around London South Bank University Who have Stopped Smoking

“…These reported experiences of participants resonate with the works of Pratt et al . [23] and Joo et al [2]. They demonstrated that individuals trying to stop smoking most likely experience shame, judgemental and embarrassing situations as well as victim blaming, within their social network.…”

“…Nicotine is a very addictive substance and the active component in tobacco, hence, the smoking behavior or constant repeated use of tobacco. However, smoking cessation is any process of discontinuing the excessive use of tobacco products [2].…”

The smoking population is not hardening in South Korea: a study using the Korea Community Health Survey from 2010 to 2018

“…Hardening indicators, such as quit attempts and quit plans, may have limitations for evaluating hardening because they cannot transform completely into successful cessation 36 37. However, they have been shown to predict future smoking cessation38 and have been used frequently as hardening indicators in numerous studies 9 14 15 22. For the quit ratio as a hardening indicator, it cannot be established when quitting occurred.…”
