Objective The objective of this article is to investigate whether excessive screen time exposure is associated with non-migraine headache and migraine in young adults. Background Increased levels of television time have been associated with increased risk of headache. However, time spent using newer electronic devices with a screen (smartphone, tablet) has not been examined yet. Methods We conducted a cross-sectional study among 4927 participants of the French i-Share cohort. Demographic characteristics, screen time exposure (computers, tablets, smartphones and television) as well as headache/migraine symptoms were recorded in a standardized questionnaire. Multinomial logistic regression models were used to evaluate the association between screen time exposure and headache status. Results Participants had a mean age of 20.8 years and 75.5% were female. The multivariable model showed that students in the highest screen time exposure quintile had an increased risk for migraine. The odds ratio (OR) (95% confidence interval (CI)) was 1.37 (1.14 to 1.66) for migraine when compared with students without headache and with low screen time exposure. This association was somewhat stronger for migraine without aura (OR = 1.50, 95% CI 1.19 to 1.89). We found no significant association between screen time exposure and non-migraine headache. Conclusion High levels of screen time exposure are associated with migraine in young adults. No significant association was found with non-migraine headache.

Objectives: The aim was to evaluate the association of self-perceived levels of attention deficit and hyperactivity symptoms with non-migraine and migraine headaches among university students. We also evaluated their association with migraine aura.Methods: Study subjects were all participants in the internet-based Students Health Research Enterprise. Scores were built to evaluate global attention and hyperactivity symptom levels, self-perceived attention deficit levels and self-perceived hyperactivity symptom levels based on the Adult Attention Deficit and Hyperactivity Disorder Self-Report Scale (ASRS v1.1.). We used standardised questions to classify headache and group participants into "no headache," "non-migraine headache," "migraine without aura" or "migraine with aura".Results: A total of 4816 students were included (mean age 20.3 ± 2.8 years; 75.5% women). Compared with participants without headache, we found significant associations between global ADHD scores and migraine. Students in the highest quintile of global ASRS scores had adjusted odds ratio (aOR) of 1.95 (95% CI 1.56-2.45) when compared to the lowest. This association was mainly driven by an association between self-perceived hyperactivity and migraine with aura. The aOR for migraine with aura was 2.83 (95% CI 2.23-3.61) for students in the highest quintile of hyperactivity. No significant association was found for any attention and hyperactivity symptom level measure and non-migraine headache and between self-perceived levels of attention deficit and migraine.Conclusions: Among students in higher education in France, self-perceived levels of attention deficit and hyperactivity symptoms were selectively associated with migraine. The association was strongest for the hyperactivity domain and migraine with aura. [ABSTRACT FROM AUTHOR]
