Child deaths linked to cousin marriages in England rise amid debate on public health risks

Data shows a troubling increase in child deaths associated with consanguinity in England, sparking political and community debates over cultural practices and health policies.

Mortality records reveal a troubling rise in child deaths linked to cousin marriages in England, with more than two such deaths occurring each week during the year to March 2024. Data prepared for the National Health Service (NHS) show that consanguinity was a contributory factor in 128 child deaths within that period, marking an increase compared to figures from seven years earlier. The average weekly death rate of 2.47 children in this context surpasses the one child per week killed through homicide in England and Wales, as per the Office for National Statistics.

Cousin marriages, particularly prevalent among South Asian and Islamic communities such as those of Pakistani heritage, represent longstanding cultural traditions intended to preserve family wealth, cultural identity, religious beliefs, and extended kinship networks. Yet the practice carries significant medical consequences. Although British Pakistani families account for under 4% of births, they disproportionately represent about a third of cases involving genetic disorders in children. These include fatal conditions affecting the skin, brain, muscles, as well as ailments causing blindness, deafness, heart and kidney failure, neurological disorders, and other serious physical and intellectual disabilities. Many affected children die shortly after birth, while thousands more survive with lifelong debilitating health problems requiring intensive healthcare.

This public health issue, prominently documented in the Bradford area—a city where cousin marriages are common—has been the focus of several major studies. Research from the Born in Bradford study highlighted that children born to first cousins face a more than doubled risk of congenital defects, such as heart and lung abnormalities, cleft palates, and other birth defects. While the absolute risk remains low, the incidence in Bradford is nearly twice the national average, raising significant concern among healthcare professionals. These findings were echoed in a parliamentary debate in June 2025, which underscored the heightened risk of serious birth defects among children of closely related parents.

The debate over cousin marriage has intensified politically and socially. Conservative MP Richard Holden has called for a governmental ban on first-cousin marriages, branding the practice as both a public health threat and a constraint on women’s freedoms. Holden’s comments followed a contentious NHS England Education Programme report that controversially suggested some economic and social benefits to cousin marriages while acknowledging the increased genetic risks. The report faced criticism for appearing “woke” and was subsequently removed from official websites. Opponents of a ban, including independent MP Iqbal Mohamed and ethicists from the Oxford Uehiro Centre for Practical Ethics, argue that a legislative ban would be ineffective, potentially eugenic, and that educational initiatives would be a more productive approach to mitigating risks without stigmatizing communities.

Internationally, some countries have taken stricter measures. Norway outlawed cousin marriage last year, and Sweden is anticipated to enact similar legislation soon. Others argue that banning cousin marriage does not eliminate the risk of genetic illnesses but rather shifts the demographic composition of affected children. This perspective calls for nuanced strategies centred on community education and expanded health services to reduce incidence rates and support affected families.

The issue remains deeply complex, balancing respect for cultural traditions and identities against urgent public health concerns. Families affected by genetic disorders linked to consanguinity, such as those recounted in Bradford, highlight the personal and emotional toll alongside statistical data. As the UK grapples with the question of potential legal restrictions or educational reforms, the priority for healthcare providers remains clear: to offer skilled care to children born with genetic conditions and to engage communities in informed dialogue about the implications of consanguineous marriages.

⚠️ The narrative originates from the Daily Mail, a publication known for sensationalist reporting. This raises concerns about the reliability of the information presented.

Plausability check

Score:
5

Notes:
⚠️ The claims about child deaths linked to cousin marriages are plausible and have been reported in other reputable outlets. However, the lack of supporting detail from other reputable sources in this report is concerning. The tone and language used are consistent with the region and topic, but the structure includes excessive or off-topic detail unrelated to the claim, which may be a distraction tactic.
