Eating Disorders Affecting More Women in Their 40s and 50s
In a UK study of more than 5,000 women, over 3% were found to have an active eating disorder in mid-life. A figure higher than expected as eating disorders are primarily associated with teenagers or young adults. The research was published in the open access journal BMC Medicine.
This is the first time the prevalence of eating disorders has been investigated in women in their forties and fifties. The researchers were surprised to find that a significant number of women in this age group were affected.
Around 15.3% of women in the study reported having an eating disorder at some point in their life and 3.6% reported an eating disorder in the past 12 months.
Less than 30% of women who had eating disorders said they had sought help or received treatment.
Dr. Nadia Micali, lead author from the Department of Psychiatry at Icahn School of Medicine at Mount Sinai in New York and University College London, London 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."
The researchers also assessed factors that may be associated with the onset of an eating disorder including 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, and 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 woman'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 others' 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 20% reduced chance of developing bulimia.
The study used data from the Women from the Avon Longitudinal Study of Parents and Children cohort to assess how many women have or had an eating disorder at some point in their life.
Women selected for the study were asked to complete a questionnaire where each eating disorder they had experienced in their life was recorded.
Women who reported having ever had any symptoms of eating disorders, and an equal number of women who reported never having symptoms, were interviewed using standardized diagnostic interviews. Women who reported experiencing any eating disorder were asked if they had ever sought and/or received treatment for these.
This study was observational and longitudinal, so it can increase our understanding of possible links between early risk factors and eating disorders, but it cannot show cause and effect.
