Methods: We examined 151 nurses with and 156 nurses without premenstrual syndrome in current study (totally: 307). Data were collected through interviews using socio-demographic questionnaire, Pre-menstrual Symptom Scale, Food Frequency Questionnaire and International Physical Activity Questionnaire. The carbohydrate quality index was calculated by sum of scores including solid carbohydrate/total carbohydrate, total dietary fiber, GI, and whole grains/total grains. We were utilized Independent sample t-test, Chi-square, One-way analysis of variance, analysis of Covariance and Logistic regression tests to analyze the data. Results: After adjusting for covariates, participants in the highest quartile of carbohydrate quality index had lower odds ratio of premenstrual syndrome (odds ratio: 0.97, confidence interval: 0.50-1.86) compared with the lowest quartile. However, this difference was not significant (P-trend=1.0). In addition, no relationship was found between premenstrual syndrome and carbohydrate quality index subscales including glycemic index, solid carbohydrate/total carbohydrate, total dietary fiber, and whole grains/total grains. Conclusions: There is no relationship between different dietary carbohydrate indices and premenstrual syndrome, although further studies are needed to fully determine the possible associations.   https://jnsd.tums.ac.ir/index.php/jnsd/article/view/298
