Assessment and treatment of the anorexia of aging: a systematic review

Assessment and treatment of the anorexia of aging: a systematic review
Assessment and treatment of the anorexia of aging: a systematic review
Background: appetite loss in older people, the ‘Anorexia of Aging’ (AA), is common, associated with under-nutrition, sarcopenia, and frailty and yet receives little attention. This review had two aims: describe interventions for AA and their effectiveness, and identify the methods of appetite assessment. (2)

Methods: study inclusion: participants aged ≥65, intervention for AA, and appetite assessment, any design, and comparator. Exclusion: studies on specific health cohorts. Searches in four databases with hand searching of references and citing works. Two researchers independently assessed eligibility and quality.

Results: Authors screened 8729 titles, 46 full texts. Eighteen articles were included describing nine intervention types: education (n = 1), exercise (n = 1), flavor enhancement (n = 2), increased meal variety (n = 1), mealtime assistance (n = 1), fortified food (n = 1), oral nutritional supplement (ONS) (n = 8), amino acids (n = 1), and medication (n = 2). Three studies evaluated combinations: education + exercise, ONS + exercise, and ONS + medication. Five intervention types exhibited favorable effects on appetite but in single datasets or not replicated. Appetite was assessed predominantly by Likert (n = 9), or visual analogue scales (n = 7).

Conclusions: a variety of interventions and methods of appetite assessments were used. There was a lack of clarity about whether AA or undernutrition was the intervention target. AA is important for future research but needs standardized assessment so that effectiveness of a range of interventions can be fully explored.

Abstract

Background: appetite loss in older people, the ‘Anorexia of Aging’ (AA), is common, associated with under-nutrition, sarcopenia, and frailty and yet receives little attention. This review had two aims: describe interventions for AA and their effectiveness, and identify the methods of appetite assessment. (2)

Methods: study inclusion: participants aged ≥65, intervention for AA, and appetite assessment, any design, and comparator. Exclusion: studies on specific health cohorts. Searches in four databases with hand searching of references and citing works. Two researchers independently assessed eligibility and quality.

Results: Authors screened 8729 titles, 46 full texts. Eighteen articles were included describing nine intervention types: education (n = 1), exercise (n = 1), flavor enhancement (n = 2), increased meal variety (n = 1), mealtime assistance (n = 1), fortified food (n = 1), oral nutritional supplement (ONS) (n = 8), amino acids (n = 1), and medication (n = 2). Three studies evaluated combinations: education + exercise, ONS + exercise, and ONS + medication. Five intervention types exhibited favorable effects on appetite but in single datasets or not replicated. Appetite was assessed predominantly by Likert (n = 9), or visual analogue scales (n = 7).

Conclusions: a variety of interventions and methods of appetite assessments were used. There was a lack of clarity about whether AA or undernutrition was the intervention target. AA is important for future research but needs standardized assessment so that effectiveness of a range of interventions can be fully explored.
