Facilitators and barriers to the implementation of dietary nutrition interventions for community-dwelling older adults with physical frailty and sarcopenia: A qualitative meta-synthesis.

This is a qualitative synthesis of perceptions, not a trial, so it cannot show whether any intervention improved frailty, sarcopenia, or physical function. Six included studies combined dietary nutrition with exercise, so the effect of nutrition advice alone cannot be separated from exercise guidance. The included studies were from economically developed countries only, with seven in Europe and one each in North America, Asia and Oceania, so transfer to other settings is uncertain. The review did not disaggregate findings by gender, age, or cultural group, and it treated facilitators and barriers as separate levels even though they may be intertwined. The quality assessment description was inconsistent: it stated studies scoring below 7 would not be included, but also stated low-quality studies were not excluded. Only five databases were searched, so some relevant qualitative studies may have been missed.

Do not read these themes as proof that dietary nutrition alone improves frailty or sarcopenia. The paper synthesizes experiences and views, and several included interventions combined dietary nutrition with exercise, so the contribution of any single component cannot be separated.
