“…This research proposes an empirical model of the relation� ship between suicide attempts and other health�risk and problem behaviors. Our study confirms specific lit� erature findings [7,22,23] that teenage suicidal behav� iors are influenced by a broad range of factors. Accord� ing to the univariate analysis, many adolescents report� ed one or more risk or problem behaviors.…”

“…Although suicidal behaviors are clearly complex and multifactorial [7], some risk factors tend to serve as common denominators in a large pro� portion of cases, one of them being substance use and abuse. A large number of studies have demonstrated that suicide attempts are more likely to occur among adolescents who drink frequently or heavily and among adolescents who use illicit drugs [3,4,8,9].…”

“…Another large-scale study was conducted by Voracek et al in Austria. They evaluated 65,206 suicide attempts between 1970 and 2006 and found no relationship between lunar phases and suicide attempts [19]. In the present study, we also did not find any significant relationship between suicide attempts and lunar phases.…”

Aim: Suicide is when a person intentionally ends his or her own life. Today, it is considered a global concern. It is important to address the underlying causes leading to suicides. In this study, we aimed to investigate the relationship between the lunar cycle and suicide attempts. Material and Method: This multicenter study was done retrospectively between January 1, 2012 and December 31, 2012. The records of patients who presented to emergency departments (EDs) with attempted suicide at nine different hospitals across the country were evaluated retrospectively. The lunar phases of the days when patients presented to the hospitals were also evaluated. Results: As determined by an investigation of the days of presentation of the 5,647 patients who were investigated, 25.28% of the patients presented during the first quarter, 25.71% during the full moon, 25.03% during the last quarter, and 23.68% during the new moon. There is, therefore, no significant difference observed between the lunar phases and suicidal attempts (P <0.05). Discussion: The results of the present study and the literature findings do not support the hypothesis of the lunar cycle having any effect on suicide attempts.

“…Unfortunately for this theory, higher tides do not occur only during the full moon but approximately twice a month, around the new moon and the full moon due to the alignment of the sun, moon, and earth. 33 There was no increase in suicides 34,35 or traumas during the full moon. 29 Ultimately, could the full moon, whether through sleep deprivation or other mechanism, create a significant change in human behavior?…”
