In Pakistan, cousin marriages are a long-standing cultural tradition, with an estimated 60% of unions taking place between blood relatives. However, this deeply rooted practice is now under scrutiny due to its alarming link with birth defects. According to recent studies and health experts, approximately 33% of all birth defects in Pakistan are associated with consanguineous (cousin) marriages.
When two closely related individuals marry, there is a significantly higher chance that both carry the same recessive gene mutations. This increases the risk of genetic disorders in their children, including physical deformities, intellectual disabilities, and rare metabolic conditions. In some rural and less educated communities, the awareness about these risks remains extremely low, and cousin marriage continues to be seen as a way to maintain family ties, property, and honor.
This health crisis places a growing burden on Pakistan’s fragile healthcare system. Children born with birth defects often require long-term medical care, therapies, and emotional support resources that are scarce and expensive.
To address the issue, public health officials and NGOs are advocating for awareness campaigns that educate families about the genetic risks of cousin marriages. Genetic counseling is also being encouraged before marriage, especially among families with a history of inherited disorders.
While changing cultural traditions takes time, promoting education, medical access, and open dialogue can help reduce the high rate of birth defects and protect future generations in Pakistan. Addressing this issue is not just a medical necessity but a social responsibility.
