Background: The anorexia of ageing is important in the development of malnutrition, frailty and sarcopenia amongst the older population and is a particular problem for hospital inpatients. This study assessed appetite-related factors in a group of hospitalised older adults, to identify potential preventive strategies., Design: Cross sectional observational study., Setting: Eleven wards in one large hospital in England., Subjects: Older inpatients aged ≥70 years, admitted non-electively., Methods: Appetite was assessed using the four-item Simplified Nutritional Appetite Questionnaire (SNAQ). Associations between SNAQ score and appetite-related factors present in the dataset were assessed in continuous analyses, including habitual physical activity, mood, medication, cognition and living circumstances., Results: 200 participants, mean age of 80.7 years (SD 6.9); 40% were women. Prevalence of poor appetite was 43%. In univariate analyses, lower medication count, higher habitual physical activity and better mood were associated with higher SNAQ scores during admission. In a multivariate analysis, independent associations of higher habitual physical activity and better mood with higher SNAQ scores during hospital admission remained., Conclusion: In this group of older adults, better mood and higher habitual physical activity were independently associated with better appetite during hospital admission. These are potentially modifiable factors and could be targets for future research into interventions for the anorexia of ageing in the hospitalised older population., (© The Author(s) 2022.

Objectives: Appetite loss is common in hospitalised older individuals but not routinely assessed. Poor appetite in hospital has previously been identified as predictive of greater mortality in the six months following discharge in a single study of female patients. The present study aimed to assess this association in a larger sample including both hospitalised men and women., Design: Longitudinal observational study with six month follow up., Setting: Acute hospital wards in a single large hospital in England., Participants: Older inpatients aged over 70 years., Measurements: Appetite was assessed using the Simplified Nutritional Appetite Questionnaire (SNAQ) during hospital stay. Deaths during six month follow-up period were recorded. Association between SNAQ score during hospital admission and death 6 months post-discharge was assessed using binary logistic regression in unadjusted and adjusted analysis., Results: 296 participants (43% female, mean age 83 years (SD 6.9)) were included in this study. Prevalence of poor appetite (SNAQ score <14) was 41%. In unadjusted analysis a SNAQ score of <14 was associated with a 2.47 increase in odds of mortality at six months (OR 2.47 (95% CI 1.27,4.82)). This association remained after adjusting for number of comorbidities (Charlson index), length of stay and gender (OR 2.62 (95% CI 1.30, 5.27)). In unadjusted continuous analysis, every one point decrease in SNAQ score led to a 1.20 fold increase in odds of mortality at six months (OR 1.20 (95% CI 1.06-1.36)). This association remained in adjusted analysis (OR 1.22 (95% CI 1.07-1.39))., Conclusion: Poor appetite is common in hospitalised older people. We have confirmed the association, previously reported in older women, between poor appetite during hospital stay and greater mortality at six months post-discharge but in a larger study including older men and women. Further research is needed to understand the mechanisms of poor appetite, which lead to increased mortality., Competing Interests: The authors declare no conflict of interest.

Introduction: Appetite loss in older people -anorexia of ageing (AA) - is common. Recognised consequences include under nutrition, sarcopenia, frailty, and increased mortality after discharge from hospital. Identification and management of AA may prevent onset of these health burdens. Whilst appetite can be assessed, this is often not routine. Methods: Cross-sectional data from three studies (carried out 2010-2017), with comparable data collection methods and drawn from the same population, were combined. Participants were over 70 years, admitted to acute wards within a large UK hospital. Appetite was assessed using the simple 4 item Simplified Nutritional Appetite Questionnaire (SNAQ); a score of ≤14/20 defines poor appetite. Correlates of SNAQ scores were evaluated. Results: The dataset included 474 participants (64% female) with mean age 84 (6.5), median Barthel 78 (IQR 53-91), mini-mental state exam (MMSE) 27 (IQR 23-29) and comorbidity index 5 (IQR 4-7). The median GDS for the population was 4 (IQR 4-6). The mean SNAQ score was 13.9 (SD 2.6), and 265 (56%) participants scored ≤14 indicating poor appetite. There was no significant difference between mean SNAQ scores of men and women (P=.26), or those living alone and with others (P=.62). Age, MMSE, comorbidity index, and total number of medications were not related to SNAQ score in continuous analyses but geriatric depression score (GDS-15) was (adjusted coefficient -.248; P<.001); such that lower mood was associated with poorer appetite. Conclusions: These findings highlight the importance of assessing appetite in hospitalised older people, as poor appetite is very common. Appetite can be assessed in hospital using the simple 4 item SNAQ tool. Subclinical low mood, measured by GDS-15, had the strongest association with SNAQ score whilst in hospital. Therefore, for those with poor appetite in hospital, clinicians should have a low threshold to evaluate and treat low mood. [ABSTRACT FROM AUTHOR]
