Association Between Suicidal Behavior and Clinical Features of Premenstrual Syndrome and Menstrual History: A Cross Sectional Study.

backgroundThe link between suicidal behavior and premenstrual syndrome has been poorly studied. This study aimed to determine the association of suicide attempts, and suicidal ideation and signs and symptoms of premenstrual syndrome and menstrual history in women in Durango City, Mexico.

methodsUsing a cross-sectional study design, 437 women were interviewed to obtain clinical data about their premenstrual period, menstrual history and suicidal behavior. Logistic regression was used to assess the association between suicide behavior and clinical features of women. Odds ratio (OR) adjusted by age, presence of mental illness, and residence area, and 95% confidence interval (CI) were obtained.

resultsOf these women, 29 (6.6%) had a history of suicidal ideation, and 15 (3.4%) had a history of suicide attempts. Logistic regression showed that suicidal ideation was associated with the variables: presence of irregular periods (OR = 2.89; 95% CI: 1.10 - 7.55; P = 0.03), low back pain (OR = 4.57; 95% CI: 1.31 - 15.92; P = 0.01), desire to eat certain food or eat a lot (OR = 2.47; 95% CI: 1.10 - 5.57; P = 0.02), guilty feeling (OR = 2.43; 95% CI: 1.06 - 5.59; P = 0.03), and aggressiveness (OR = 3.19; 95% CI: 1.42 - 7.13; P = 0.005). Whereas logistic regression showed that a history of suicide attempts was associated with the variables: presence of irregular periods (OR = 9.57; 95% CI: 1.23 - 74.44; P = 0.03), and desire to eat certain food or eat a lot (OR = 3.08; 95% CI: 1.04 - 9.15; P =0.04).

conclusionsIn this first study on the link of suicide behavior and clinical features of premenstrual syndrome, results suggest that suicidal ideation and suicide attempts are associated to specific signs or symptoms of premenstrual syndrome. Further research to confirm the findings of this study is needed. Results might help for an optimal planning of preventive measures against suicide.
