Supplementary file 1_Diet quality in pediatric migraine and the educational quality of related short-form videos: a cross-sectional study and content analysis.zip

Caregiver use of short-form videos was also surveyed. In addition, 150 videos on dietary and lifestyle management of pediatric migraine from Douyin, Kuaishou, and Xiaohongshu were analyzed for educational quality, reliability, and actionability.</p>Results<p>The high-CCDI group had lower PedMIDAS scores than the low-CCDI group (29.54 ± 17.20 vs. 41.96 ± 14.72), fewer headache days over 28 days [6.00 (4.00, 8.00) vs. 9.00 (8.00, 11.00)], lower pain intensity, and fewer days of analgesic use (all p < 0.001).

Caregiver burden and anxiety and depression scores were also lower (all p < 0.05). After adjustment, higher CCDI scores remained associated with lower PedMIDAS scores, fewer headache days, lower pain intensity, fewer days of analgesic use, and lower caregiver burden. Diet and lifestyle management was the most frequently searched topic (30.6%), yet only 34.4% of caregivers fully verified video recommendations with a physician.

Although 90.0% of videos provided recommendations concordant with clinical guidelines or evidence-based recommendations, reliability, actionability, and nutrition follow-up remained limited; nutrition follow-up was addressed in only 23.33% of videos.</p>Conclusion<p>Higher overall diet quality was associated with lower migraine burden and caregiver burden in children with migraine. These findings support the relevance of overall dietary assessment, while prospective studies are needed to clarify temporal and causal relationships.

Short-form videos are an important source of dietary and lifestyle information for caregivers, but their reliability, actionability, and follow-up content require improvement.</p>
