Undernutrition (wasting) is still frequent in patients infected with the huma immunodeficiency virus (HIV), despite recent decreases in the prevalence of undernutrition in western countries (as opposed to developing countries) due to the use of highly active antiretroviral treatment. Undernutrition has been shown to have a negative prognostic effect independently of immunodeficiency and viral load.

These guidelines are intended to give evidence-based recommendations for the use of enteral nutrition (EN) by means of (ONS) and tube feeding (TF) in HIV-infected patients
