%X The objective of this study was to evaluate the relationship between food intake and serum levels of leptin and ghrelin in the luteal (LP) and follicular (FP) phases of the MC (menstrual cycle) in participants with and without PMS (premenstrual syndrome).
This was a case-control study with healthy participants aged 20-45 years with regular menstrual cycles (24-35 days) with and without PMS. After the Daily Record of Severity of Problems (DRSP) was filled out for two months (PMS diagnosis), a nutritional assessment was carried out based on twelve food intake records (for two menstrual cycles) to quantify food intake.
Of the 69 participants analyzed, 35 experienced PMS and 34 did not experience PMS. For participants with PMS, calorie and carbohydrate intake was higher during LP than in FP (p = 0.004 and p = 0.003, respectively), whereas these changes were not observed in participants without PMS (p > 0.05). There were interactions between the groups and the MC phases (LP and FP) for the intake of calories (p = 0.028) and carbohydrates (p = 0.001). There was a marginal negative relationship between the levels of ghrelin and calorie intake in FP (rS = -0.314, p = 0.066) in the PMS group and a negative relationship between the levels of ghrelin and leptin in LP (rS = -0.490, p = 0.004) in the group without PMS.
These results indicated a higher calorie and carbohydrate intake during LP in participants with PMS, in addition to the hypothesis that the roles of ghrelin and leptin in energy regulation may be different in participants with PMS compared to those without PMS.
