One in 14 children who die in England have closely related parents, study finds

The National Child Mortality Database (NCMD) at the University of Bristol released a groundbreaking study on child mortality in England on Thursday, revealing that one in 14 children who died between April 2019 and March 2023 had parents who were closely related. Researchers analyzed data from 13,045 child deaths occurring over this four-year period to identify the correlation between consanguinity—the practice of marrying close relatives—and infant mortality. The report was commissioned to provide a clearer understanding of the underlying causes of pediatric deaths and to address significant health disparities across different socio-economic and ethnic groups. The findings highlight a disproportionate impact on specific communities and regions, with the study noting that deaths linked to consanguinity were most prevalent in cases involving chromosomal or genetic abnormalities. While the overall number of deaths remains relatively low in the broader context of the population, the data suggests that approximately 7% of all recorded child deaths in England involve parents who are second cousins or closer. This statistical insight provides a critical link between hereditary genetic conditions and the higher mortality rates observed in families with a history of intermarriage. Beyond genetic factors, the NCMD report emphasizes a complex interplay between ethnicity and socio-economic deprivation. The study found that children from South Asian backgrounds and those living in the most impoverished areas of England faced significantly higher risks of mortality. This overlap of factors has led medical experts and child safety advocates to call for urgent public health interventions. They argue that cultural sensitivity must be balanced with transparent medical advice to ensure that families at high risk of genetic complications receive adequate screening and genetic counseling. Public health officials are now facing pressure to improve data collection and provide clearer communication regarding the risks of consanguineous relationships. The report concludes that addressing these disparities is essential for reducing the national child mortality rate. By identifying these specific vulnerabilities, the University of Bristol researchers hope to influence future healthcare policies, ensuring that preventative measures and specialized diagnostic services are directed toward the communities that need them most.
