Abstract
Objective: To analyze sex differences in demographic and clinical characteristics of individuals who died by suicide in Mexico City.Method: Statistical analysis of residents of Mexico City whose cause of death was suicide, during two years period from January 2014 to December 2015, with a coroner's report. Suicide mortality rates were calculated by age, sex, and location within the city. The Chi-squared test was used to assess statistical differences.Results: From January 2014 to December 2015, 990 residents of Mexico City died by suicide (men: 78.28%, women: 21.72%). Among males, the highest mortality rates were among the groups of 20–24 and 75–79 years old, whereas in women, the group with the highest mortality rate was 15 to 19 years old. 74% of the sample used hanging as suicide method. However, men had higher rates of a positive result in the toxicology test (40%) (p < 0.05). There was no concordance between male and female suicide by city jurisdictions.Conclusion: Our results provide evidence that the characteristics of Mexico City's residents who committed suicide had significant sex-related differences, including where they used to live. Understanding the contributory factors associated with completed suicide is essential for the development of effective preventive strategies.
Highlights
Suicide is a major worldwide public concern that causes almost half of all violent deaths of males and 71% in the female population, which translates to about 800,000 suicides per year [1]
Nine hundred and ninety deaths were identified as suicides between January 2014 and December 2015 in Mexico City: 775 men (78.28%) and 215 women (21.72%)
We found that the distribution of deaths rates within Mexico City (16 Administrative Jurisdictions) were not similar for males and females (Spearman, Rho = 0.125, n = 16, p = 0.323)
Summary
Suicide is a major worldwide public concern that causes almost half of all violent deaths of males and 71% in the female population, which translates to about 800,000 suicides per year [1]. In Mexico, suicide rates have been increasing over the past 40 years, affecting more men than women [2]. The suicide rate for men increased from 5.95 to 8.50 (per 100,000 inhabitants) from 2000 to 2015, and from 1.06 to 2.00 for women [3, 4]. Suicide in Mexico City observed in the number of suicides between 2000 and 2014 in Mexico City [4]. In this context of increasing suicide rates, the study of suicide related to demographic and clinical risk factors has special relevance
