Mental Health and Medicine Use for Headache: A Nationally Representative Study of Adolescents in Denmark

Abstract

PurposeThis study examined the prevalence of headache medicine use among Danish adolescents and explores the link between mental health, frequent headaches, and medicine use for headache. We hypothesized that poor mental health increases headache occurrence, leading to greater medicine use.MethodsThe 2022 Danish Health Behaviour in School‐aged Children (HBSC) study surveyed 5292 students aged 11, 13, and 15. Self‐reported data included headache frequency, medicine use for headache, and five mental health indicators: life satisfaction, emotional symptoms, loneliness, self‐efficacy, and self‐esteem. Multivariate logistic regression analyses assessed the association between mental health indicators and headache medicine use, adjusting for headache frequency.ResultsWeekly headaches were reported by 33.1%, and 43.6% used headache medicine in the past month. Poor mental health correlated with higher headache and medicine use rates. Analyses adjusted for sex, age group, and occupational social class found significantly increased odds ratios (95% confidence interval) for medicine use for headache among students with low life satisfaction (2.27; 1.88–2.75), among students with 2+ emotional symptoms (2.28; 1.92–2.69), students who often felt lonely (2.08; 1.69–2.55), students with low self‐efficacy (1.37; 1.16–1.61) and students with low self‐esteem (1.59; 1.36–1.85). When accounting for headache frequency, the association between poor mental health and medicine use diminished and became nonsignificant.ConclusionsPoor mental health was linked to increased medicine use for headache. The findings suggest that frequent headaches may explain the association between poor mental health and the use of headache medicine. Promoting rational medicine use and enhancing mental health among adolescents is essential.
