Research paper thumbnail of Energy intake and expenditure: Validation of a diet history by heart rate monitoring, activity diary and doubly labeled water

Design: Energy intake (EI) estimated by a diet history (DH) was validated against total energy expenditure (TEE) measured by doubly labeled water (DLW) (n 12) used as reference, by heart rate monitoring (HR) and by an activity diary (AD). Setting: MJad. Mean difference between DH and DLW was 1.28 (s.d. 2.17) MJ (NS) and the DHaDLW ratio was 0.88. Four subjects were identi®ed as under-reporters and one as an over-reporter. Conclusion: The DH slightly underestimated EI compared to the HR, but was in concordance with the AD. Compared to DLW, DH underestimated EI by 12%. On group level, the DH method gave comparable values to HR and AD. The DH was not valid for ranking of individuals. Compared to DLW, the HR method seemed to perform somewhat better than the AD for detection of under-and over-reporters.

We aimed to investigate and quantify the extent of nutrition impact symptoms (NIS) in patients with COPD and to explore relationships between NIS and fat-free mass depletion. The results in this cross-sectional study are based on 169 COPD patients (62% female subjects). Body composition was assessed using bioelectrical impedance spectroscopy and the patients reported NIS by two newly developed questionnaires: the Eating Symptoms Questionnaire (ESQ) and the Disease-Related Appetite Questionnaire (DRAQ). Symptoms with the highest prevalence were dry mouth (71%), stomach ache (39%), pain or aches affecting appetite (36%) and constipation (35%). Problems with diarrhoea and feeling affected by smells were more severe among women compared with men (P<0.05). Thirty-six percent of the patients were depleted (fat-free mass...

Cohort study. Departments of Geriatric Medicine and Clinical Nutrition, Göteborg University, Gothenburg, Sweden. 369 males and 440 females from three representative cohorts of free-living individuals from the gerontological and geriatric population studies--H70. Man values for EI/BMR(est) was 1.50 and 1.60 in males and 1.48 and 1.49 in females according to Schofield, Schofield and James (1985) and DHSS 41 (1991), respectively. A significant trend was seen when the sample was stratified at different levels of EI/BMR(est) with higher body weight, lower EI, higher proportion of energy from protein and lower of proportion energy from fat in the group with the lower values of EI/BMR(est). A significant difference was shown regarding food choice expressed as proportion of energy from ten defined food groups with respect to different EI/BMR(est) values. Lean body mass (LBM) by bioelectric impedance (BIA) correlated well with BMR according to DHSS 41 (1991), 0.90 for males and 0.87 for females. Energy intake was underreported with the DH method--especially in over-weight individuals. Reported food choice varied with EI/BMR values. EI/BMR(est) limits are useful for detecting underestimation of habitual energy intake.

Research paper thumbnail of Consensus definition of sarcopenia, cachexia and pre-cachexia: Joint document elaborated by Special Interest Groups (SIG) “cachexia-anorexia in chronic wasting diseases” and “nutrition in geriatrics”

Although simple and effective tools for the accurate screening, diagnosis and treatment of malnutrition have been developed during the recent years, its prevalence still remains disappointingly high and its impact on morbidity, mortality and quality of life clinically significant. Based on these premises, the Special Interest Group (SIG) on cachexia-anorexia in chronic wasting diseases was created within ESPEN with the aim of developing and spreading the knowledge on the basic and clinical aspects of cachexia and anorexia as well as of increasing the awareness of cachexia among health professionals and care givers. The definition, the assessment and the staging of cachexia, were identified as a priority by the SIG. This consensus paper reports the definition of cachexia, pre-cachexia and sarcopenia as well as the criteria for the differentiation between cachexia and other conditions associated with sarcopenia, which have been developed in cooperation with the ESPEN SIG on nutrition in geriatrics.
