Biological Determinants Of Suicide

Decent Essays

Suicide among males is approximately 3 and a half times higher than among females. That’s likely because men tend to choose more violent methods such as the use of guns and hanging. That seems to be statistically true, because while successful suicide among men is 3 and a half times higher than females, females ATTEMPT suicide or have thoughts about suicide about 3 times as often than males. Suicide is also the second leading cause of death globally in individuals aged 15–29 years old. Globally, every 40 seconds an individual commits suicide, and that’s projected to double to be every 20 seconds by 2020.
There are also some issues related to suicide with the fact that a lot of people don’t seek help. In order for an individual to feel empowered …show more content…

In a study of genetic variants associated with suicide featured in the article Exploring the Determinants of Suicidal Behavior: Conventional and Emergent Risk (DISCOVER): a feasibility study, it says that “suicide attempts were associated with a different genetic profile than completed suicide.” This suggests that suicidal behavior is in fact NOT a spectrum of severity but would be better characterized as categories with different risk factors for each category. In suicide cases versus non-suicidal control groups, the most common biological marker for suicide is lowered concentrations of the serotonin metabolite 5HIAA in the cerebrospinal fluid. It has also been shown that suicidal patients had high serum cortisol concentrations when compared to non-suicidal controls. And increased release of dexamethasone in the brain can also be a predictor of …show more content…

The physical environment contributes to overall quality of life and wellness, and what has been found is that while seasonal depression is common throughout darker and colder months, not every population climate in low and middle-income countries (LMIC) are going to experience this. An example of why the data shows this, but it does not happen, is because of how research is often reflecting high-income countries (HIC) data. The WHO reports that only 6% of research done on suicide is done in LMIC. (HYPERLINK TO THIS STAT TOO) BUT, Pollution is a major determinant as gaseous air exposure and pollution contribute to acute medical conditions that tend to increase suicidality and decrease quality of life. According to the article Decomposing the association of completed suicide with air pollution, weather, and unemployment data at different time scales, environmental risks, such as pollution and weather, attributed to 33.7% of suicide data in Taiwan. Ozone concentrations also had a strong association with suicide
