Abstract
BackgroundThe objective of this study was to examine the relationship between employee work schedule and failure in smoking cessation.MethodsLogistic regression was used to estimate the association between work schedule and failed smoking cessation rate among 4927 male workers who had attempted smoking cessation. The data was obtained from the annual Korean National Health and Nutrition Examination Survey from 2007 to 2015 (excluding data from 2013). An adjusted model, including demographic and occupational variables, was constructed after stratifying the data into two subgroups by age (the 19- to 40-year-old group and the 41- to 60-year-old group).ResultsThe percentage of smoking-cessation failure varied according to work schedule and age. The failure rate in the 19- to 40-year-old group was generally higher for all work schedule categories than in the 41- to 60-year-old group. In particular, the highest percentage (90.9%) of smoking-cessation failure was in the fixed overnight work group. After adjusting for demographic characteristics and work organization variables, the odds ratio for failed smoking cessation across all ages was 3.30 (95%CI 2.23–4.86) among the fixed overnight workers compared to the daytime workers. Both of the age-stratified subgroups maintained this relationship, with a notably higher OR in the 19- to 40-year-old group (OR 3.74, 95% CI 1.80–7.77).ConclusionsFixed overnight work is likely to negatively affect smoking cessation compared to other work schedules. Tailored anti-smoking intervention programs are required based on work schedule.
Highlights
The objective of this study was to examine the relationship between employee work schedule and failure in smoking cessation
The characteristics were quite varied according to age as the younger male workers were more likely to be night workers, non-manual workers, or permanent workers; more educated; less likely to be married; and had more stress than the older male workers
The characteristics varied according to work schedule (Table 2)
Summary
The objective of this study was to examine the relationship between employee work schedule and failure in smoking cessation. Smoking prevalence has been declining during the recent decades [1], it is still high in Korea, with an estimated 42.1% of South Koreans being smokers in 2013 [2]. This plays a major role in respiratory diseases, such as lung cancer, chronic obstructive pulmonary disease, and bronchitis, as well as cardiovascular diseases such as hypertension, coronary artery disease, and angina [1, 3]. The mechanisms of the diseases associated with night work are rather complex, though a general mechanism could be the disturbance of the circadian rhythm [10]. When melatonin, which is secreted mostly after sunset and decreases right
