The possible factors affecting suicide attempts in the different phases of the menstrual cycle

Abstract

This study was designed to investigate whether there is a relationship between the menstrual cycle and suicide attempts, and to determine the factors affecting suicide attempts in different phases of the menstrual cycle. The study sample included 52 women who were admitted to the emergency room because of a suicide attempt. The incidence of suicide attempts in menstrual follicular phase (MFP) was significantly higher than in other phases. No significant difference of socio-demographic and clinical characteristics was observed between MFP and the other phases. Also, hormone levels of patients who attempted suicide were not different from those of healthy control subjects. In spite of the fact that suicide attempts were often made in MFP, there was substantial difficulty in explaining why this frequency was different than other phases. Furthermore, the event may be linked to low estrogen and progesterone levels in this phase. It has, however, been thought that hormonal effects cannot be responsible alone for suicide attempts.
