Migraine attacks among medical students in Soochow University, Southeast China: a cross-sectional study

Migraine is one of the most common primary headache disorders and is burdensome to both the individual and society, influencing the academic performance and quality of daily lives of medical students worldwide. This study aimed to investigate the migraine prevalence in a sample of university medical students in China and to examine the features and typical trigger factors of migraine among these students.

From May 2016 to August 2016, a total of 1,060 medical students who were enrolled in Soochow University in Jiangsu Province in China were chosen through stratified random sampling. A self-administered questionnaire that included the ID Migraine™ for screening of migraine cases was used to collect data. The frequency, severity, duration of migraine attacks, and relevant trigger factors were measured for migraine cases. In total, 986 students completed the questionnaire.

The overall migraine prevalence among students was 7.91%, with 4.64% in male and 9.84% in female students. Junior-grade students had a higher migraine prevalence than senior students (prevalence of migraine of year 1 to year 5 undergraduates: 10.83%, 8.9% vs. 6.25%, 4.42%, 5.33%, P<0.05; prevalence of migraine of year 1 to year 3 graduates: 9.68%, 9.71% vs. 6.38%, P<0.05). Students with a positive family history were more likely to suffer migraine than those without (OR=8.48, 95% CI: 4.33-16.59). Stress (n=73, 93.59%), lack of sleep (n=72, 92.31%), and change of sleeping time (n=68, 87.18%) were the top three trigger factors among the students.

Migraine was common among medical students from a university in China, and especially higher in female and junior-grade students, and those with a family history of migraine. Reducing stress and improving sleep quality might be effective to reduce migraine attacks in this population.
