Secondary data analysis reveals smokers have poorer sleep quality and increased daytime sleepiness in long-haul truck drivers, indicating a need for targeted interventions.
Objective: To describe smoking prevalence among long-haul truck drivers (LHTDs) and assess differences in sleep quality, quantity, and propensity between smokers and non-smokers. Methods: Sleep quality was measured using the Pittsburgh Sleep Quality Index, and sleep propensity using the Epworth Sleepiness Scale. Data were analyzed in RStudio using descriptive statistics, Shapiro-Wilk, Levene’s Test, Mann-Whitney U Tests, and Cohen’s D. Results: Among 96 LHTDs surveyed, 63 were non-smokers, and 33 were smokers. Smokers reported significantly higher daytime sleepiness scores (p =.038, d = 0.2), while differences in sleep quality and sleep propensity duration were not statistically significant Conclusions: Individuals who smoke experienced poorer sleep quality and greater daytime sleepiness. These findings underscore the need for larger studies and targeted interventions to address smoking-related sleep issues in LHTDs.
