Objective: The present study aims to examine the effects of cigarette consumption on physical activity, nutrition, and sleep quality in young adults. Methods: A descriptive, cross-sectional study was conducted among 1163 young adults studying at a public university in eastern Türkiye. The participants were divided into groups based on the amount of daily cigarette consumption. The International Physical Activity Questionnaire (IPAQ), Richards-Campbell Sleep Questionnaire (RCSQ), and Mediterranean Diet Adherence Screener (MEDAS) scales were used for data collection. Correlation analysis was conducted to examine the relationships between variables. Additionally, regression analysis was used to determine the effect of cigarette consumption on physical activity, nutrition, and sleep quality. Results: Findings revealed that 68.6% of participants had irregular eating habits, 59.9% did not engage in regular exercise, and approximately half reported sleeping 7-8 hours per day. Non-smoking status was positively correlated with higher physical activity (r=.25, p<.05), better sleep quality (r=.30, p<.05), and stronger adherence to the Mediterranean diet (r=.20, p<.05). Conversely, cigarette consumption showed significant negative correlations with IPAQ (r=-.10 to - .35, p<.05), RCSQ (r=-.18 to - .28, p<.05), and MEDAS scores (r=-.08 to - .25, p<.05). Regression analyses indicated that cigarette consumption accounted for 38.3% of the variance in physical activity (F=22.37, p<.05), 33.9% in sleep quality (F=15.48, p<.05), and 10.1% in diet adherence (F=17.28, p<.05). Conclusion: Higher cigarette consumption among young adults is associated with lower physical activity, poorer sleep quality, and reduced adherence to the Mediterranean diet, and also significantly predicts variations in these health behaviors.
