“…This review shows that the prevalence rate of smoking in Yemen, Palestine, Bahrain, Jordan, Tunisia, Egypt, UAE and KSA had a higher prevalence which were observed among males more than females (36.3% vs 28.0%), (52.7% vs 16.5%), (27.0% vs 4.2%), (54.3% vs 11.1% and 56.9% vs 11.4%),(38.4% vs 3.4%), (61.2% vs 18.9%), (33.0% vs 3.9%) and (32.7% vs5.9%) respectively (Nasser and Zhang, 2019;Musmar, 2012;Alzayani and Hamadeh, 2015;Obeidat et al, 2014;Khader and Alsadi, 2008;Maatouk et al, 2013;Khan et al, 2012;Mandil et al, 2005) and (Mandil et al, 2011) (Table1). This is compatible with many studies conducted in Mediterranean and Arab countries that indicates a significantly higher prevalence of smoking among males, which may be due to the social acceptability of the smoking habit among males (Metintaş et al, 1998;Haddad and Malak, 2002;Hasim, 2000;Melani et al, 2000;Bener et al, 1999). A literature review of smoking in KSA (Bassiouny, 2009) confirms that smoking was reported to be higher among males compared to females, regardless of the age group of study (school children, university students, adults).…”
