Objective:
To examine psychological and behavioural variables associated with the disordered fluid intake of 112 eating disorder patients.
Method:
Fluid intake history for previous seven days, and standardized psychological and behavioural measures of eating disorders, mood, personality and health, were completed on admission to hospital.
Results:
Only behaviours associated with eating disorders were associated with fluid intake. Greater amounts of total and energy-free fluids are consumed if patients report overeating, binge eating and dieting between overeating more frequently, drinking more caffeine-containing energy free drinks, vomiting and using laxatives. Energy-containing fluid intake is higher if patients feel their body weight is less important and if they binge eat. There is a significant difference in the amount of fluid drunk (ml or ml/kg) by patients with bulimia nervosa (BN) when compared to patients with no current diagnosis but not compared with anorexia nervosa (AN) or eating disorders not otherwise specified (EDNOS) patients.
Discussion:
Fluid intake is associated with eating disorder behaviour rather than personality and psychological variables. Patients eating more drink more.
