Relationship between dietary intake, eating attitudes, and premenstrual syndrome severity among Iranian women: insights from a cross-sectional study
Abstract
Background: Premenstrual syndrome (PMS) is a common issue that impacts many women, and a well-balanced diet can help alleviate PMS symptoms. Evidence suggests that dietary factors and eating disorders may influence PMS severity, yet the specific relationships remain unclear. This study aimed to evaluate the association of specific dietary components and eating behaviors with PMS symptoms.
Methods: This cross-sectional study was conducted on 252 women with PMS who were referred to healthcare centers in Qazvin province. Data concerning PMS, dietary factors, and eating disorders were collected using online questionnaires, including the premenstrual symptoms screening tool (PSST), 3-day dietary recall, and Eating Attitudes Test-26 (EAT-26) questionnaires. Statistical analysis utilized ANOVA and chi-square tests. The adequacy of the sample was evaluated using the Kaiser-Meyer-Olkin (KMO) test. To examine the relationship between eating disorders, dietary factors, and PMS symptoms, multivariable linear regression analysis was conducted. Statistical significance was set at p < 0.05.
Results: According to the PSST, 28.7% of individuals reported mild severity, 21.9% reported moderate severity, and 49.4% reported severe severity. The study revealed that higher sodium (p = 0.003, OR = 1.000, 95% CI = [1.000, 1.001]), vitamin D (p = 0.044, OR = 1.298, 95% CI = [1.007, 1.674]), and vitamin C intake were positively linked to increased psychological PMS symptoms, (p = 0.036, OR = 1.006,…
