摘要:Background : The ongoing Syrian war has resulted in many changes in the social and economic life of Syrians. To date, no study has documented the relationship between smoking behaviour and the war. Aim : To determine the prevalence of cigarette smoking among university students during the crisis in Damascus, Syrian Arab Republic, and the impact of the war on smoking behaviour. Methods : We conducted an anonymous online cross-sectional survey of 1027 undergraduate students from all years and colleges at Damascus University. Results : The overall prevalence of tobacco smoking was 24.73% for cigarettes and 30.4% for waterpipe. Prevalence of cigarette smoking was significantly higher in men, non-health profession students, and in students living away from their families. There was no significant difference in prevalence of smoking cigarettes when comparing students according to their origin (urban vs rural), year of study, and change of residence due to war. War was associated with a significant increase in mean number of cigarettes smoked daily, and 53.1% of smokers reported that the number of cigarettes consumed per day had increased since the beginning of the war. Conclusions: Increased smoking is an additional health concern in areas of conflict and may require special consideration and efforts by public health authorities.
