According to foreign media reports on May 23, a recent new study shows that in the average family, the brother and sister suicide rate is higher than that of the older brother and sister. The study conducted by the University of Stockholm counted suicides, confirming that more than 20% of them were related to their birth order and the age of the mother at birth.
According to a study published in the American Journal of Epidemiology, early-born children have a 18% lower suicide rate than adults who are born late. The main researcher, Michael Josteda, said that our research findings are significant, which proves that the birth order should be considered in the early living environment factors that affect people's mental health.
According to the study, recent studies have shown that the birth order is related to the risk of suicide, and the later the child is born, the higher the risk of suicide. More than 20% of suicide cases are the result of a combination of child birth order and maternal age. Researchers say they are still unclear why children with late birth orders have a higher suicide rate. This means that experts may lack information that can effectively interfere with the suicide of children born late in birth. At the same time, the study also found that younger siblings in the family are more likely to die in accidents. Children born later in the home are usually more likely to be suicidal than their older brothers and sisters. Several studies in the past have shown that birth order is related to human health.
A February study showed that older brothers and sisters have a higher probability of developing diabetes and heart disease. This is related to the metabolic pattern during development in the mother. However, the factors in the growth of different families are too complicated to judge.
According to another Norwegian study published in the American Journal of Epidemiology, the risk of suicide increases by 46% for every one birth delay. New research confirms this view. José and his team recorded birth and death rates in Sweden from 1931 to 1980, recording mortality rates from 1981 to 2002. They found that the later the birth order, the higher the suicide rate.
The correlation between birth order and suicide rate is very obvious. Even if these people are born at different ages, the number of brothers and sisters is different, the marital status is different, and the socioeconomic status is different, this relationship still exists.
If Disra says the reason for this connection is not clear, but the underlying cause may be that they are vulnerable to bullying by their older siblings. And relative to my brother and sister, parents often give them less attention than the first child. A lower level of attachment to parents may result in emotional behavioral disorders, separation of stress and mental illness, which in turn gives them a higher suicide rate. Another possibility may be a biological explanation that pregnant women who are not first born may have higher levels of cortisol, a substance that may affect brain development.
