Abstract
Cognitive dietary restraint has been previously reported in nutrition and dietetics (ND) students. However, its influence on energy intake (EI) in this population is yet to be investigated. Therefore, the aims of this study were: 1) to determine daily energy and macronutrient intake of ND students and compare to those enrolled in occupational therapy (OT) degree; 2) to explore associations between energy and nutrient intake, and cognitive restraint (CR) of this group. Data was collected in August-December 2013. Demographic and diet-related information was gathered by a demographic questionnaire. CR was assessed using the scale of the Three Factor Eating Questionnaire (TFEQ-R18). Dietary intake was evaluated via three 24-hour dietary recalls, and resting metabolic rate (RMR) was measured through indirect calorimetry. Sixty-three students (81% female) age 18-51 years and body mass index 22.5±3.9kg.m-2 participated. Out of n=51 females, n=38 were ND and n=13 were OT. All male participants (n=12) were enrolled in ND. Daily EI was similar in ND and OT females. Male participants reported higher EI and RMR than female (2813±918kcal.d-1 and 1856±328kcal.d-1, p<0.01; 1681±253kcal.d-1 and 1328±156kcal.d-1, p<0.01 respectively). Mean CR was 48.2±15.8, with 50% males and 69% of females categorised as having high restraint. CR did not influence energy or macronutrient intake, apart from a significantly lower fat intake in males with high CR (87.7±12.5g.d-1 compared to 130.7±14.6g.d-1, p=0.05). Almost third of participants (93% of these female) were classified as low EI reporters based on EI: RMR ratio; however, association with CR was not detected. In conclusion, although CR was relatively high in all students, it appeared to have no impact on energy and macronutrient intake except fat for intake in males. Replication of this study in a larger group of participants is needed to build an understanding of the influence CR may have on energy and macronutrient intake in this population.
