Headache was reported in 87 (60.8%) participants. The prevalence increased significantly with age, from 43.8% among children aged 7–9 years to 71.4% among those aged 13–15 years (P=0.038). Headache was reported in 67.7% of females compared with 55.1% of males, although the difference was not statistically significant (P=0.125). Among children with headache, 52.9% reported at least one episode per week, while moderate headache was the most common severity category (56.3%). Significant associations were observed with sleep duration <8 hours (70.4% vs. 48.4%, P=0.012), screen exposure ≥2 hours/day (69.7% vs. 46.3%, P=0.008), low or irregular physical activity (68.6% vs. 49.1%, P=0.021), irregular meals (69.6% vs. 50.0%, P=0.018), positive family history of headache (75.0% vs. 51.7%, P=0.008), and academic or psychological stress (70.8% vs. 50.7%, P=0.019). In the estimated multivariable analysis, family history (adjusted OR=2.67, 95% CI: 1.31–5.44, P=0.007), screen exposure ≥2 hours/day (adjusted OR=2.31, 95% CI: 1.17–4.57, P=0.016), sleep duration <8 hours (adjusted OR=2.18, 95% CI: 1.08–4.40, P=0.030), and low or irregular physical activity (adjusted OR=1.92, 95% CI: 1.01–3.67, P=0.047) remained independently associated with headache.
