The associated factors for cephalalgia were: female sex (OR = 2.2; 95%CI 1.4 - 3.4), Common Mental Disorder (OR = 2.8; 95%CI 1.7 - 4.9), vision impairment (OR = 2.6; 95%CI 1.6 - 4.2), besides back pain (OR = 2.2; 95%CI 1.3 - 3.5), sinusitis (OR = 2.0; 95%CI 1.2 - 3.4) and incomplete elementary education (OR = 3.0; 95%CI 1.6 - 5.6).
