Background and purpose: Increased headache frequency and severity have been observed in obese populations, but the real impact of a weight loss treatment on headache has not been studied. We investigated this issue in a sample of obese adolescents.
Methods: In all, 135 migraineurs, aged 14-18 years, with body mass index (BMI) ≥ 97 th percentile, participating in a 12-month-long program, were studied before and after treatment. The program included dietary education, specific physical training, and behavioral treatment.
Results: Decreases in weight (P < 0.01), BMI (P < 0.01), waist circumference (P < 0.01), headache frequency (P < 0.01) and intensity (P < 0.01), use of acute medications (P < 0.05), and disability (P < 0.05) were observed at the end of the first 6-month period and were maintained through the second 6 months. Both lower baseline BMI and excess change in BMI were significantly associated with better migraine outcomes 12 months after the intervention program.
Conclusions: Significant improvements in both adiposity and headache data were observed in obese adolescents with migraine who participated in a 12-month-long interdisciplinary intervention program for weight loss. Initial body weight and amount of weight loss may be useful for clinicians to predict migraine outcomes.
