General practices have recorded a large rise in eating disorder diagnoses and self-harm episodes amongst teenage girls in the UK in the years since the Covid-19 pandemic, a research team has found.
The study conducted jointly by Keele University, The University of Manchester, University of Exeter, and mental health research charity The McPin Foundation, has been published in the Lancet Child and Adolescent Health
The analysis of UK GP records of young people aged 10 to 24 years between 2010 and 2022 showed that since March 2020, eating disorders were 42% higher than would be expected based on previous trends for females aged 13-16, and 32% higher for those aged 17-19.
The increase in incidence of self-harm was also greatest among females aged 13-16, with the number of episodes being 38% greater than expected.
In contrast, there was no evidence of an increase in self-harm incidence in females in the other age groups and no increase in rates of eating disorders or self-harm was observed in males.
For the 10-year period before the pandemic, diagnoses of eating disorders in females were more common in those from more affluent backgrounds than those from more deprived communities, say the team.
This socioeconomic difference has widened following the onset of the pandemic: since March 2020, eating disorder diagnoses for females living in the least deprived communities were 52% higher than expected, compared with 22% higher for those living in the most deprived areas.
Unlike eating disorders, rates of self-harm were higher in the most deprived areas in the 10-year period prior to the pandemic, but unlike for eating disorders, the socioeconomic differences narrowed rather than widened after March 2020.
Self-harm and eating disorders, as well as being major health issues in their own right, are coping mechanisms that are often indicative of underlying psychological distress, and they share multiple risk factors.
Professor Carolyn Chew-Graham, Professor of General Practice Research at Keele University, who is also a practising GP, said: “Early identification of mental health difficulties in children and young people by primary care clinicians is extremely important as this facilitates timely access to treatments. Sufficient support, however, from GPs and mental health services needs to be available to manage those presenting.
“Given the current pressures on the NHS, in both primary and specialist care, our study emphasises the need for sufficient capacity in mental health services to meet growing demand.”
The study is funded by the National Institute for Health and Care Research (NIHR) School for Primary Care Research and the NIHR Greater Manchester Patient Safety Research Collaboration.
Lead author Dr Pearl Mok from The University of Manchester said: “The reasons for the increase in eating disorder diagnoses and self-harm episodes amongst teenage girls during the pandemic are likely to be complex and could be due to a mixture of issues such as social isolation, anxiety resulting from changing routines, disruption in education, unhealthy social media influences, and increased clinical awareness.
“Our study is large, but episodes of self-harm that were not treated by health services were not captured in our data, so the rise in self-harm incidence might have been even greater than we observed. However, it is also possible that cases of self-harm not coming to the attention of services may have exhibited a different pattern.
“We found that the increase in eating disorders and self-harm was greater in less deprived than in more deprived areas. This may reflect differences in service provision and challenges in accessing clinical care, rather than greater increases in risks for self-harm and eating disorders during the pandemic amongst those living in the least than in the most deprived communities.”
