Results: According to PSST, the prevalence of PMS and PMDD were 47.5 % and 13.0%, respectively. From logistic regression analysis, PMS was significantly associated with chocolate consumption (P < 0.01), no banana consumption (P < 0.05), weight change (P < 0.05), menstrual irregularity (P < 0.05), dysmenorhea (P < 0.05), myalgia (P < 0.01) and benzodiazepines use (P < 0.05), whereas PMDD was significantly associated with financial inadequacy (P < 0.05), chocolate consumption (P < 0.01), no banana consumption (P < 0.05), abnormal length of
menstrual cycle (P < 0.05), and dizziness during menstrual period (P < 0.05).
