Like obesity and type 2 diabetes, eating disorders (anorexia nervosa, bulimia nervosa, binge eating disorder, and other specified feeding and eating disorders) are associated with adverse prenatal and perinatal conditions. However, unlike obesity and type 2 diabetes, the prenatal and perinatal risk factors associated with eating disorders have not been analysed through the lens of health inequalities. This is an important gap. While eating disorders are commonly depicted as conditions that afflict middle-class women, recent studies have found that adults who experience economic precarity are more likely to endorse disordered eating attitudes and practices, suggesting that low socioeconomic status may be associated with the development of eating disorders. The proposed project will develop the first prospective analysis of the influence of parental socioeconomic status on children's disordered eating in adolescence. The project will use data collected as part of ALSPAC (Avon Longitudinal Study of Parents and Children). The ALSPAC cohort includes 14,000 children born between 1991 and 1993, who have been followed intensively since the early 1990s until the present day, with clinical assessments and self administered questionnaires charting the children's development into adulthood from physiological, emotional, cognitive, behavioural, and social angles. Notably, ALSPAC collects detailed longitudinal data on parental socioeconomic status, maternal eating disorders, and children's disordered eating, allowing for an analysis of the influence of parental socioeconomic status on children's disordered eating. The proposed project is therefore uniquely positioned to examine an important gap in the literature which, if confirmed, will reposition eating disorders within the health inequalities field.
