Supportive interventions for enhancing dietary intake in malnourished or nutritionally at-risk adults: a systematic review of nonrandomised studies

摘要

BackgroundSupportive interventions for enhancing dietary intake in malnourished or nutritionally at risk adults are frequently recommended. A recent systematic review of randomised controlled trials identified limited and poor quality evidence to support their use. Observational studies have been shown to compliment and extend their evidence. This review aimed to synthesise evidence from nonrandomised studies aiming to improve nutritional intake in nutritionally vulnerable individuals and to describe their effects on cost, nutritional, clinical and patient centred outcomes.
