Abstract

Background

We evaluated risk factors associated with chronic headache (CH) such as age, gender, smoking, frequent drinking of alcoholic beverages (drinking), obesity, education and frequent intake of acute pain drugs to test their usefulness in clinical differentiation between chronic migraine (CM) and chronic tension-type headache (CTTH).

Methods

We used baseline data from the population-based German Headache Consortium Study including 9,944 participants aged 18–65 years, screened 2003–2005, using validated questionnaires. CM and CTTH were defined according to IHS criteria. Multinominal logistic regression analyses were used to investigate the association of CM or CTTH with risk factors by estimating odds ratios (OR) and 95% confidence intervals (95%CI).

Results

The prevalence of CH was 2.6% (N = 255, mean age 46 ± 14.1 years, 65.1% women), CM 1.1% (N = 108, 45 ± 12.9 years, 73.1%), CTTH 0.5% (N = 50, 49 ± 13.9 years, 48.0%). Participants with CM compared to CTTH were more likely to be female (OR: 2.34, 95%CI: 1.00-5.49) and less likely to drink alcohol (0.31, 0.09-1.04). By trend they seemed more likely to smoke (1.81, 0.76-4.34), to be obese (1.85, 0.54-6.27), to report frequent intake of acute pain drugs (1.68, 0.73-3.88) and less likely to be low educated (0.72, 0.27-1.97).

Conclusions

We concluded that the careful assessment of different risk factors might aid in the clinical differentiation between CM and CTTH.
