Abstract:
Introduction: The prevalence of dietary supplement usage for fitness objectives is rising,
particularly among gym participants, and is influenced by diverse sociodemographic
factors. Recognizing these connections is important for planning interventions to enhance
health outcomes and facilitate informed decision-making within this demographic.
Objective: To assess dietary supplement usage and the association with socio-
demographic factors on supplement utilization among male gym participants in the Jaffna
district.
Methodology: A descriptive cross-sectional study was conducted among gym attendees in
Jaffna, including Nallur, Kopay, Chavakachcheri, and Point Pedro. Male participants aged
18 to 60 years were randomly selected. Data was collected via interviewer-administered
questionnaires. Statistical analysis was performed using SPSS 20 software, and ethical
clearance was obtained from the Ethical Review Committee, Faculty of Medicine,
University of Jaffna.
Results: The study comprised 422 participants with a 100% response rate. A majority
(50.7%) were classified as overweight, and 62.8% were aged over 35 years. Most
participants did not utilize supplements; among those who used supplements with the
primary focus on bodybuilding. Dietary supplement usage exhibited significant
associations with age (p<0.001), BMI (p<0.001), and education level (p<0.001).
Conclusion: Gym attendees use various supplements, predominantly for general fitness
purposes. Sociodemographic factors such as age, BMI, and education level significantly
influence supplement usage patterns among participants.
