Here’s a startling fact: one in every 14 children who died in England over a four-year period had parents who were close relatives, according to a groundbreaking study that’s turning heads and sparking conversations. But here’s where it gets controversial—while the exact number of children with closely related parents isn’t clear, the data screams one thing loud and clear: these children are disproportionately represented in mortality statistics. And this is the part most people miss: the study, published by the National Child Mortality Database (NCMD) at the University of Bristol, analyzed all 13,045 child deaths between 2019 and 2023, finding that 926 (7%) were born to consanguineous parents—meaning their mother and father are close blood relatives, like first cousins. This isn’t just a number; it’s a call for urgent action, say researchers.
To put this into perspective, a large-scale study in Bradford, tracking 13,000 babies, found that one in six children had parents who were first cousins, with the majority coming from the city’s Pakistani community. Prof Karen Luyt, director of the NCMD, calls this analysis ‘the first of its kind globally,’ offering a comprehensive look at how consanguinity impacts child mortality over time. ‘The data is undeniable,’ she adds. ‘These children are overrepresented in mortality statistics, and we need to act now to improve their outcomes.’
But it doesn’t stop there. The report also sheds light on stark ethnic and socioeconomic disparities. Of the children who died with closely related parents, four in five (79%) were from Asian backgrounds, with Pakistani ethnicity being the most common. Even more striking? Almost a third (30%) of deceased children from Asian backgrounds had closely related parents, compared to just 5% from Black backgrounds and 1% from white or mixed backgrounds. And when it comes to socioeconomic status, over half (52%) of these children lived in England’s most deprived areas, while only 5% were from the least deprived.
Here’s the kicker: previous studies have shown that children born to closely related parents are twice as likely to have congenital anomalies and face higher risks in speech and language development. In this study, more than a quarter (27%) of all child deaths were linked to chromosomal, genetic, or congenital anomalies, and nearly three in five (59%) of these deaths occurred in children with closely related parents. That’s almost 17% of all genetically linked child deaths.
The NHS isn’t ignoring this. A spokesperson highlighted the report as ‘clear evidence of the increased risks’ and pointed to a pilot program training specialist nurses to prevent deaths in vulnerable babies, particularly in areas where close-relative marriages are common. But here’s the question: Is this enough? And how do we balance cultural practices with public health concerns? Let’s hear your thoughts in the comments—this is a conversation we can’t afford to ignore.
