Abstract
Previous studies suggest that factors related to smoking cessation may vary with age. This study examined the factors affecting smoking cessation by age among Korean adult male smokers using data from the Korea National Health and Nutrition Examination Survey from 2007 to 2018 (excluding 2013). Logistic regression analyses were used to investigate various factors associated with smoking cessation in three different age groups. Out of a total of 15,492 individuals, 31.5% of the 3523 individuals aged 19–39 years (young adult), 54.7% of the 7390 individuals aged 40–64 years (middle-aged), and 78.6% of the 4589 individuals aged ≥65 years (older adults) succeeded in quitting. In the young adult and middle-aged groups, being married was associated with successful quitting, and lifetime smoking was associated with unsuccessful quitting. Willpower and several comorbidities were related to successful cessation in the middle-aged and older adult groups. Skipping any meal, which suggests unhealthy behavior, was negatively related to quitting in the young adult group. We observed that factors associated with smoking cessation success or failure differed by age, which should be considered when developing smoking cessation policies and programs.
Highlights

The prevalence rates of smoking cessation in all age groups have increased over time since 2007
Several studies have been conducted in this reHowever, a meta-analysis showed that interventions that enhance partner support have gard, but our study examined the factors related to smoking cessation by age among Kono impact on increasing long-term abstinence from smoking [30]
Summary
The number of smokers is decreasing worldwide, more than 1.1 billion people reportedly smoked in 2015 [1]. In South Korea, the smoking rate for adult males was reported to be 38.1% and. A national survey that investigated the factors influencing successful smoking cessation in adult Korean males found age to be a key factor. The success rate of quitting smoking was significantly higher in older men [8]. A few previous studies, including some conducted in Korea, reported that older individuals are more likely to succeed after making a quitting attempt [8,9,10,11,12]. One survey showed that older cigarette smokers are less likely than younger adults to be interested in quitting smoking, making quitting attempts, and achieving smoking cessation [13]. Smokers who start smoking later in life tend to be more likely to quit [14,15,16,17]
