The impact of migraine on quality of life in the general population: the GEM study (see comments)

摘要

OBJECTIVE: To assess health-related quality of life (HRQOL) in migraineurs in the general population. DESIGN: Cross-sectional study within the context of a population-based study monitoring health characteristics of the Dutch adult population in two municipalities representative of the general population in the Netherlands. Migraine was assessed in a multistaged procedure that included a semistructured clinical interview by telephone. Final diagnosis met 1988 International Headache Society criteria. HRQOL was measured with the self-administered RAND 36-item Health Survey (RAND-36), including physical functioning, social functioning, role limitations, and physical perception. HRQOL of migraineurs was compared with that of nonmigraineurs. To compare and study the effect of comorbidity, the authors also identified subjects with asthma or chronic musculoskeletal pain. There were 5998 people with complete data, 620 of whom had migraine in the last year. RESULTS: Compared with nonmigraineurs, significantly more migraineurs had asthma (OR = 1.6; 95% CI 1.1, 2.4) or chronic musculoskeletal pain (OR = 1.7; 95% CI 1.5, 2.1). Migraineurs reported diminished functioning and well-being on all eight domains as compared with nonmigraineurs. HRQOL was inversely related to attack frequency (p < 0.0002). Migraineurs had a poorer HRQOL than did those reporting asthma, except for dimensions concerning physical functioning and general health perception, but they had a better HRQOL than did subjects with chronic musculoskeletal pain. Comorbidity of asthma or chronic musculoskeletal pain in migraine further reduced HRQOL. CONCLUSIONS: Migraineurs report more asthma and chronic musculoskeletal pain. Compared with nonmigraineurs and to others with chronic conditions, migraineurs report compromised physical, mental, and social functioning, particularly those with a high frequency of attack.
