Background and Aims Premenstrual syndrome (PMS) disrupts lives of girls who otherwise would lead more productive lives. We assessed prevalence and severity of PMS in adolescents of Anand, a small town in western India and identified probable associations with age, locality, food habits, obesity, stress, genetic influence, menorrhagia and dysmenorrhoea.
Methods Cross sectional observational study in which Premenstrual Symptoms Screening Tool for Adolescents (PSST-A) questionnaire was self-administered to screen PMS and Premenstrual Dysphoric Disorder (PMDD). 1355 girls of Gujarati ethnicity in age group 10 to 23 years with regular menstrual cycles participated. Obesity was assessed through Body Mass Index. Results were examined for associations that could indicate effect of lifestyle on PMS/PMDD.
Results The prevalence of moderate to severe PMS was 17.3% and PMDD was 4.7%. 95.0% girls had at least one PMS symptom, 68.8% had at least one moderate to severe PMS symptom, 49.9% had one or more physical symptoms and 89.8% had more than one PMS symptom. 37.1% had disruption of daily activities while 24.2% remained absent from school/college due to PMS. 75.4% girls felt that PMS was a normal part of menstruation and 50.0% reported moderate to severe stress. 21.4% had physical symptoms every menstrual cycle. Age, weight, BMI, stress level, dysmenorrhoea and menorrhagia contribute significantly to PMS, whereas menorrhagia, stress level and junk food contribute significantly to PMDD.
Conclusion Prevalence of moderate to severe PMS and PMDD in this population is higher than reported elsewhere. PMS interferes with day to day life significantly.
