Background To explore whether the use of cigarettes affects the prevalence of obstructive sleep apnea (OSA) in adults. Methods A questionnaire-based cross- sectional study was conducted among 233 participants. The questionnaire link was published on November 13, 2023 on social media sites and the Internet.The adults were divided into four groups: noncurrent smokers, current electronic cigarettes (e-cigarette) users only, current conventional cigarettes (c-cigarette) users only, and dual users. OSA was assessed by three main signs and symptoms from the questionnaire. Multivariable logistic regression after adjusting for covariates was conducted to investigate the association of OSA with different smoking patterns. The sample size was calculated as 233 to a population of 12,900000 with a margin error of 5% and a confidence interval of 95% using a sample size calculator. Conclusion Our study found that 68% of sleep apnea patients were smokers, with 24% passive smoking, 36% smoking regular cigarettes, 24% smoking hookah, and 8% smoking electronic cigarettes, which confirmed that sleep apnea is more related to smoking regular cigarettes than Electronic cigarettes
