Abstract
Menstrual cycle phase-dependent changes in appetite in women with premenstrual syndrome has not thus far been systematically demonstrated. In this study of 21 patients with premenstrual syndrome and 13 control subjects, there were significant increases in appetite in both groups, with a greater effect of menstrual cycle phase on appetite in the patients. Further, the premenstrual increase in appetite was highly correlated with self-ratings of mood (particularly depression) in the patients only. The authors discuss these findings with respect to endocrine influences on appetite regulation and potential implications for investigation of atypical depression.
