To meta-analyse or not to meta-analyse: abortion, birth and mental health.

Two recent meta-analyses claim that abortion leads to a deterioration in mental health. Previous reviews concluded that the mental health outcomes following an unwanted pregnancy are much the same whether the woman gives birth or terminates the pregnancy, although there is an increased mental health risk with an unwanted pregnancy. Meta-analysis is particularly susceptible to bias in this area. The physical health outcomes for women with an unwanted pregnancy have improved greatly by making abortion legal. To further improve the mental health outcomes associated with an unwanted pregnancy we should focus practice and research on the individual needs of women with an unwanted pregnancy, rather than how the pregnancy is resolved.
