In-patient nutritional intervention for children and adolescents with anorexia nervosa (AN) initially involves the process of refeeding( 1 ). Refeeding is the cautious provision of adequate energy to achieve weight gain( 1 ). The aim of refeeding is to achieve medical and cognitive stability to facilitate recovery( 1 , 2 ). The recommended rate of weight gain is 0.5 to 1.0 kg/wk( 2 ), however, energy requirements to achieve this have not been established to date( 1 ). As a result, current recommendations are based on expert opinion rather than evidence( 1 ), and can range from 2000 to 7000 kcal/d (8373 to 29307 kJ/d)( 3 , 4 ). The primary aim of this study was to investigate actual energy intakes and subsequent weight gain in children and adolescents with AN during in-patient refeeding.

This study was a retrospective clinical audit of a sample of 12 children and adolescents with AN aged 11 to 15 years, admitted to a children's university teaching hospital between 2005 and 2011 for in-patient refeeding. Prescribed and reported food intakes and weight records, over the first four weeks of treatment, were collected from detailed food record charts completed by nursing staff, and analysed using Tinuviel, WISP v3.0 nutritional analysis software (Warrington, UK).

Mean prescribed energy intake over the first four weeks of refeeding ranged from 2772 kcal/d (11 605 kJ/d) over week one, to 4013 kcal/d (16 801 kJ/d) over weeks two to four. Compliance with individualised prescribed diet was achieved with mean reported energy intake ranging from 2964 kcal/d (12 401 kJ/d) over week one, to 4406 kcal/d (18 447 kJ/d) over week four. The target weight gain of 0.5 to 1 kg/wk was achieved with corresponding mean weight gain values ranging from 0.59 to 1.26 kg.

These energy intake values conform with recommendations from expert groups for refeeding in AN, and significantly exceed published energy requirements for healthy children and adolescents of similar age (11 to 18 years) and gender, which range from 1845 to 2755 kcal/d (7724 to 11 534 kJ/d)( 5 ).

Results from this study suggest that energy intakes of 3000 to 4500 kcal/d (12 560 to 18 840 kJ/d) can achieve effective weight gain in children and adolescents with AN during refeeding.
