This is the first time that the prevalence of eating disorders – conditions normally associated with teenagers and young adults – has been looked at in a large number of women in their 40s and 50s.

Dr Nadia Micali who led the research said:

'Our study shows that eating disorders are not just confined to earlier decades of life, and that both chronic and new-onset disorders are apparent in mid-life. Many of the women who took part in this study told us this was the first time they had ever spoken about their eating difficulties, so we need to understand why many women did not seek help. It may be that there are some barriers women perceive in healthcare access or a lack of awareness among healthcare professionals.'

Dr Micali and her team also looked at the factors that may be associated with the onset of an eating disorder such as childhood happiness; parental divorce or separation; life events; relationship with parents; and sexual abuse.

Dr Micali explained:

'The early risk factors we assessed were associated with different eating disorders.

Anorexia, bulimia, binge eating and purging disorder were all associated with childhood unhappiness.

Parental separation or divorce during childhood seemed to increase the risk of bulimia, binge-eating disorder and atypical anorexia.

We also found that death of a carer could increase the likelihood of purging disorder and that sexual abuse during childhood or a fear of social rejection was associated with all eating disorders.'

In this study a women’s risk of suffering from anorexia nervosa or bulimia nervosa, two of the most common eating disorders in the UK, was increased by 4-10% per unit score of ‘unhappiness’ if they reported being unhappy during childhood. 

Higher interpersonal sensitivity – the ability to accurately assess other people’s feelings – was associated with an increased risk of binge eating by 19% per unit score of ‘sensitivity’. A good mother-daughter relationship was associated with a reduced chance of developing bulimia by 20%.
