9. Birth Order Influences Risk of Mental Health Issues
Some studies suggest that birth order may influence the risk of developing certain mental health concerns. Research indicates that firstborn and only children are more likely to develop anxiety and depression by the age of 8 compared to children born second or later. (axios.com) Additionally, a study published in the European Child & Adolescent Psychiatry journal found that higher birth order was associated with an increased risk of suicide attempts and psychiatric disorders in adolescence. (link.springer.com) However, these findings are not universally accepted, and other research has found minimal or no significant effects of birth order on mental health outcomes. For example, a study published in the Journal of Affective Disorders found no significant association between birth order and the risk of developing depression.
