Various trigger factors have been reported in different populations. The current study was designed to extract the main trigger factors using factor analysis, and compare the chronic and episodic patient scores for every extracted pattern.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this cross\u2010sectional study, 300 migrainous women (25\u201355\u2009years old) participated. A constructed 46\u2010item Likert questionnaire was developed to assess the primary triggers. The validity of the designed questionnaire was assessed by Content Validity Ratio and Content Validity Index coefficients. The test\u2013retest method was employed to assess reliability. The exploratory factor analysis was performed to extract patterns of correlation among 46 triggers. Each participant was given a score for every extracted pattern. The mean scores of chronic and episodic patients were compared using the Mann\u2013Whitney test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean body mass index of participants was 28.17\u2009\u00b1\u20095.44 kg\/m<jats:sup>2<\/jats:sup>. Most participants (90.7%) had migraine without aura. Four factors were extracted using factor analysis that explained 22.37% of the total variance: (1) environmental and behavioural factors; (2) condiments; (3) nitrite, tyramine and caffeine; and (4) fats. None of these factors explained the difference between chronic and episodic migrainous women.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The current study suggests that environmental and behavioural factors, relative to dietary triggers, play an essential role in causing migraine in women and more than dietary triggers.
