Background: Premenstrual Syndrome (PMS) is a psychosomatic disorder that comprises of physical, mental and emotional symptoms that occur one to two weeks before menstruation and resolve after periods. Methods: This was a cross-sectional study conducted among the students of GMC Jammu. The research tool applied was ‘Premenstrual Symptom Screening Tool (PSST)’. Results: A total of 320 girls were enrolled in the study; out of which 184 (57.5%) had no/mild premenstrual syndrome. 84 (26.25%) had moderate/severe PMS and 52 (16.25%) suffered from PMDD. Higher prevalence of sedentary habits was seen in patients with PMS (33.08% vs 19.02%). Also, the patients with PMS had higher prevalence of high salt intake (43.38% vs 22.82%), high fat intake (33.82% vs 23.91%), coffee intake (69.85% vs 43.47%), tea intake (63.23% vs 45.65%), aerated drinks (26.47% vs 15.21%), sweets/icecreams/choclates (32.35% vs 18.47%) and lower prevalence of consumption of fruits (50% vs 60.86%) as compared to those without PMS. Conclusions: Our study found obesity, sedentary lifestyle and consumption of diet rich in salt, fat, sweets, aerated drinks as well as caffeine and low in fruits and vegetables was associated with higher prevalence of PMS.
