Therefore, we aimed to explore the impact of smoking status and nicotine dependence on the frequency and severity of primary headache disorders during fasting.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This prospective cohort study with pre\u2013post comparisons was conducted on male smokers and nonsmokers with primary headache disorders. The patients were recruited from four headache clinics in three Egyptian governorates: Cairo, Beni\u2010Suef, and Fayoum at the beginning of Shaaban. The patients were hand\u2010delivered a questionnaire containing questions targeting the last week of Shaaban and another one targeting the first week of Ramadan. Participants were instructed to resubmit their completed questionnaires electronically at the end of the first week of Ramadan. The number of headache days (NHDs), Visual Analog Scale (VAS), and Headache Impact Test\u20106 (HIT\u20106) scores, as well as the Depression, Anxiety, and Stress Scale\u201012 items (DASS\u201012) scores, were compared during the first week of Ramadan to those during the last week of Shaaban. Intensity of nicotine dependence was assessed by the Fagerstrom Test for Cigarette Dependence (FTCD).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>This study included 1023 males with primary headache disorders (400 smokers and 623 never\u2010smokers). During the last week in Shaaban, smokers were found to have significantly higher NHDs, HIT\u20106 total, and DASS\u201012 scores than the never\u2010smoked group (2 [1\u20133] vs. 1 [0\u20133], <jats:italic>p<\/jats:italic>\u2009=\u20090.001; 58 [50\u201363] vs. 56 [46\u201363], <jats:italic>p<\/jats:italic>\u2009=\u20090.021; and 16 [7.25\u201322] vs. 10 [2\u201318], <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001, respectively). The changes in NHDs, VAS, HIT\u20106, and DASS\u201012 scores during the first week of Ramadan were significantly higher in smokers than in the never\u2010smoked group (0 [0\u20132] vs. 0 [0\u20131], <jats:italic>p<\/jats:italic>\u2009=\u20090.003; 0 [0\u20132] vs. 0 [0\u20131], <jats:italic>p<\/jats:italic>\u2009=\u20090.001; 1 [\u22121 to 5] vs. 0 [\u22122 to 4], <jats:italic>p<\/jats:italic>\u2009=\u20090.008; and 0 [\u22121 to 2.75] vs. 0 [\u22122 to 0], <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001, respectively). Moreover, FTCD scores were positively correlated with changes in the NHDs (<jats:italic>r<\/jats:italic>\u2009=\u20090.26, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), VAS (<jats:italic>r<\/jats:italic>\u2009=\u20090.28, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), HIT\u20106 (<jats:italic>r<\/jats:italic>\u2009=\u20090.27, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), and DASS\u201012 (<jats:italic>r<\/jats:italic>\u2009=\u20090.38, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) scores during the first week of Ramadan. Smoking increased the odds of clinically significant worsening in HIT\u20106 by 1.44 (95% confidence interval [CI], 1.04\u20132.01) times. Among smokers, higher FTCD scores and greater change in DASS\u201012 increased the odds of worsening by 1.17 (95% CI, 1.05\u20131.30) and 1.13 (95% CI, 1.07\u20131.19) times,
