Abstract
The aim of this research was to explore the relationship of total energy and macronutrient intake, energy balance and energy availability to eating attitudes and cognitive restraint in students enrolled in undergraduate nutrition degrees. Energy and micronutrient intake was assessed in 63 students (n = 50 nutrition, and n = 13 occupation therapy degrees; n = 51 females, n = 12 males) using three 24-h dietary recalls. Energy requirements were calculated based on measured resting metabolic rate, estimated exercise energy expenditure, and dietary induced thermogenesis. Body composition was assessed using dual energy x-ray absorptiometry. Eating attitudes and cognitive restraint were measured using previously validated tools. Eighteen percent of nutrition students were classified as having low energy availability (<30 kcal kgFFM-1d-1) and 38% were in negative energy balance. Eating attitudes and cognitive restraint were not associated with total energy or macronutrient intake. However, female nutrition students with high cognitive restraint had greater exercise energy expenditure and thus lower energy availability than those with low cognitive restraint (371 (302) kcal d-1 compared to 145 (206) kcal d-1, P < 0.01, and 35 (7) kcal d-1 compared to 41 (10) kcal d-1 of fat free mass, P = 0.005). Additionally, in females, disordered eating attitudes and cognitive restraint negatively correlated with energy availability (rs = -0.37, P = 0.02 and rs = -0.51, P < 0.01 respectively). There were no differences in outcomes between nutrition and non-nutrition students. The current study suggests that that those students with disordered eating attitudes and cognitive restraint may be controlling their energy balance through exercise, as opposed to restricting food intake.
