Abstract:
Introduction: Migraine is a neurological condition categorized as a primary headache
disorder by the International Classification of Headache Disorders (ICHD-3). Migraine
affects about 30% of the global population; particularly, students seem to be more
susceptible, with rates of 20% to 52%. Academic stress, irregular lifestyles, and genetics
increase the risk for migraine and found to negatively impact academic performance and
quality of life.
Objective: To determine the prevalence of migraine and its associated factors among
undergraduate students at the Jaffna premises of University of Jaffna, Sri Lanka.
Methodology: A descriptive cross-sectional study was conducted among undergraduates
at University of Jaffna. A total of 464 students were recruited from selected faculties using
a proportionate random sampling method. To gather data, a self-administered questionnaire
was used. The data was analyzed using SPSS 27. A chi-square test was performed to
identify the associated factors. Ethical approval for the study was obtained from the Ethics
Review Committee of the Faculty of Medicine, University of Jaffna.
Results: This study investigated migraine prevalence in 464 participants including the age
range from 20 to 28 years (mean age: 23.94, SD=1.839). Female: Male ratio is 1:1. Overall,
the prevalence of migraine is 7.5%. Prevalence was highest in ages 26-28 (11.88%),
females (11.44%) and undergraduates following medical-related courses (25.74%).
Obesity (9.41%) and overweight (8.22%) exhibited higher prevalence variations. Also,
those with a family history of migraine, inadequate sleep, and lack of exercise had a high
prevalence. The identified factors associated with migraines include gender (p=0.001),
marital status (p<0.001), course of study (p<0.001), family history of migraines (p<0.001),
duration of sleep (p<0.001), tea/coffee consumption (p=0.045), and exposure to strong
odours (p=<0.001).
Conclusion: The overall migraine prevalence was 7.5% including higher rates among
females, married individuals, and those with a family history of migraines. Lifestyle
factors, including inadequate sleep and exposure to strong odors, also play a role. This
study highlights the role of demographic factors and lifestyle choices in understanding
migraine prevalence by informing targeted preventive measures.
