This guideline provides guidance on the principles and evidence-informed recommendations on the nutritional care and support for patients with tuberculosis. Undernutrition increases the risk of tuberculosis and in turn tuberculosis can lead to malnutrition. Undernutrition is therefore highly prevalent among people with tuberculosis. It has been demonstrated that undernutrition is a risk factor for progression from tuberculosis infection to active tuberculosis disease and that undernutrition at the time of diagnosis of active tuberculosis is a predictor of increased risk of death and tuberculosis relapse. However, the evidence concerning the effect of nutritional supplementation on tuberculosis prevention and health outcomes among people with tuberculosis had not previously been systematically reviewed. Member States have requested guidance from the World Health Organization (WHO) on nutritional care and support for patients with tuberculosis.

Evidence:

The primary audience for the guideline is health workers providing care to people with tuberculosis. However, the guideline is also intended for a wider audience including policy-makers, their expert advisers, and technical and programme staff at organizations involved in the design, implementation and scaling-up of nutrition actions for public health.
