1. NFHL Cohort was created in 1995 to assess the nutritional consequences of HIV infection and to determine how malnutrition adversely affects the course of the disease. The main focus of the project was on wasting.
2. Project 1, funded from 2000-2005, aims to determine whether nutrition is a predictor of clinical outcome, independently of virologic or treatment status, and to define the effects of HAART on nutritional status.
