Brief intervention using the PaperWeight Armband to identify older people at risk of undernutrition in the community: a preliminary evaluation.

The intervention is associated with positive outcomes, with reduction or stabilisation of nutritional risk in the majority of participants studied. The intervention can be delivered in a wide range of settings and does not require healthcare professions for the screening. Longer and larger studies are now required to study the health, well-being and socioeconomic impacts of the intervention in depth.
