|Title:||Prevalence and demographic risk factors for frequent headache in non-neurologic ambulatory patients [Prevalencia y factores de riesgo demogr�ficos para cefalea frecuente en pacientes ambulatorios que acuden a consulta no neurol�gica]|
|Abstract:||Introduction: Frequent headache can impact significantly daily life activities and is associated with an important consumption of drugs for pain relieving. Objective: To describe the point prevalence and demographic risk factors associated with frequent headache of moderate to severe intensity in ambulatory patients who attend non-neurologic clinics in a Mexican tertiary care center. Methods: A total of 496 patients (mean age: 47.8 years, 64.5% women) receiving medical care in non-neurologic clinics were interviewed, excluding those with known neurologic illness, apart from headache. Frequent headache of moderate to severe intensity was defined as the presence of ? 1 headache episodes per week, in the previous 3 months, with intensity ? 5 in a 0 to 10 analog scale. Logistic regression analyses were constructed to identify associated independently risk factors. Results: Moderate to severe frequent headache was identified in 194 cases (39.1%; 46% in women and 26% in men); 63% used non-steroidal antiinflammatory drugs. A significantly higher use of NSAIDs was identified in the female gender, as compared withmen (38.6 vs. 25%, respectively; p = 0.002). In a multivariate analysis adjusted for multiple confounders, 4 independent risk factors were identified: age < 45 years, hypertension, female gender and ? 6 years of school education. Conclusion: Point prevalence of frequent headache of moderate to severe intensity in ambulatory patients of non-neurologic clinics is high. Although this group of patients is not representative of the general population, it is shown here the health burden that frequent headache can impose as a relevant comorbidity.|
