Abstract

Short bowel syndrome (SBS) represents a serious intestinal absorption disorder, and patients may be prone to severe malnutrition. Dietetic therapy is critically important both for immediate prognosis and successful long-term rehabilitation. To maintain energy balance, an accurate assessment of energy intake is required. Our objective was to compare energy intake (EI) assessed by 24-h dietary recalls (EIrecall), a standard clinical assessment, with the total energy expenditure measured by the doubly labelled water (TEEdlw) method in SBS patients and matched controls. A total of twenty-two participants (eleven each in the SBS and control groups (CG), six female and five male) were evaluated; CG were matched to SBS patients on the basis of age, BMI and sex. TEE was measured by DLW and compared with EI determined by four 24-h dietary recalls using the USDA Automated Multiple-Pass Method. Bland-Altman plots and paired Student's t test were used to compare EIrecall with TEEdlw (P<0.05). Participants' mean age was 53 (sd 8) years. TEEdlw (7.85 (SD 1.16) MJ/d, 0.14 (SD 0.02) MJ/kg per d) was significantly lower (P=0.014) compared with EIrecall (11.07 (SD 3.45) MJ/d, 0.21 (SD 0.08) MJ/kg per d) in the SBS group. On the other hand, in the CG group TEEdlw (10.02 (SD 1.86) MJ/d, 0.18 (SD 0.03) MJ/kg per d) was significantly higher (P=0.001) compared with EIrecall (7.19 (SD 1.68) MJ/d, 0.13 (SD 0.03) MJ/kg per d). In SBS patients, reported EI is higher than DLW-measured EI. Therefore, providing or prescribing energetic intake based on EIrecall without accounting for potential malabsorption-related losses can compromise the energy needs in SBS patients and affect nutritional status in the long term.
