The NHS implies about 340 million pounds of pounds in additional healthcare costs per year due to weight-related health problems-but not only obesity that drives costs. New study from the University of Oxford reveals that degraded weight children need comparable medical support, such as those who are serious obese, provocative cases on childhood health priorities.
The study, published in Open the Jama Network And funded by the National Institute of Health and Care (NIHR), it provides the first national image of health care costs associated with children’s weight, using NHS electronic health records of more than 268,000 children aged 2-15 across England. He found that childhood weight issues – affecting about 2.5 million children – cost the NHS about 340 million pounds per year.
It is important that research shows that the cost of healthcare increases sharply after the official recording of a child’s weight, suggesting that recognition of weight issues causes additional medical support – but only if there are appropriate services.
Basic findings that matters for practice
The research followed the use of healthcare last year and then the children had measured their weight on GP practices, revealing the additional costs (“excessive cost”) compared to health children:
- Four to five years old with severe obesity had the highest excess cost to £ 472 per year
- Girls with severe obesity cost more than boys (£ 253 versus £ 138 per year)
- Only white children showed a clearly higher cost of health care in all unhealthy weight groups.
- The use of healthcare was significantly higher after the weight was measured for children with low weight and moderately higher for children with severe obesity.
This project suggests that we may have considered it in the wrong way. It’s not just obesity that drives cost. Children of degraded may need comparable support and produce similar costs per capita with NHS. We need to think about the full range of unhealthy weight when designing services. ”
Dr. Olu Onyimadu, Head writer from the Oxford Health Sciences Department
The findings come at a critical time, as the government implements its 10 -year health plan, which emphasizes the shift from treatment to prevention. The research offers NHS decision -making managers clear evidence of where to target resources.
Professor Stavros Petrou, author and senior NIHR researcher, said:
“These numbers give the commissioners and practices the evidence they need to make the case for weight management services.
The ethnic variants revealed in the study could help support the NHS goal more effectively. White children showed consistently higher costs when overweight or obese compared to children from other ethnic backgrounds – ideas that could help deal with health inequalities.
Professor Mara Violato, co-as the most authorized in the health of the Oxford population, added:
“With 27% of children aged 2-15 who live with overweight or obesity, as well as those affected by the degraded, we are considering a huge opportunity for preventive care.
What does this mean to families and NHS
Research shows that once the child’s weight issue is identified, the NHS responds with additional support – but it only works if there is appropriate services. The findings are boosting the financial case for investing in both prevention programs and weight management services in primary care.
For parents, findings show that concerns about children who are very thin are just as valid as overweight concerns. Research shows that as soon as weight issues are identified by GPS, children usually receive more medical support-from nutrition tips to mental health services-underlining the importance of regular checks.
For the commissioners and practices that develop business cases for new services, the study provides the strong evidence needed to show value for money. Because the methodology is aligned with the UK’s clinical standards, the findings apply immediately to NHS decisions.
The research team emphasized that these cost estimates can now be used to evaluate whether specific weight management programs provide value for money, helping NHS to make documented decisions on the interventions they will fund. Researchers note that BMI measurements are not usually recorded for all children in primary care and future research will explore standards in longer periods.
