Migraine risk factors in Qashqai migrating nomads: an adjusted multiple correspondence analysis approach

ABSTRACT

To determine the migraine risk factors in Qashqai migrating nomads using an adjusted multiple correspondence analysis approach. In summer 2006, 750 Qashqai migrating nomads aged 25 years or older in Fars Province, Southern Iran were enrolled using a multiple-stage cluster random sampling. A questionnaire consisting of demographic characteristics, lifestyle and migraine diagnosis was used for each subject. The association of each risk factor was assessed using an adjusted multiple correspondence analysis. The prevalence of migraine was 18% in males and 28% in females. It was higher in overweight and obese subjects, those who consumed roasted foods, widows, female gender and in the age group of 35-50 years old. Multiple correspondence analyses were suitable choices to determine detailed results of complex categorical data in migraine risk factors
