The aim of this review is to provide a synoptic view of functional health literacy among people living with HIV/AIDS (PLWHA) across the globe, so as to suggest directions for future research in sub-Saharan Africa. Thirteen published empirical studies from hard copy and on-line journals on the subject matter are reviewed. However, all the studies were conducted in other regions other than sub-Saharan Africa, which points up to the fact that research on the subject matter is seriously desired in the region. Based on the studies’ findings, directions for future research are outlined. These include that: 1) further research is needed to examine the role of treatment programmes in mediating relationships between individual predisposing factors and health literacy and the linkages between health literacy, and subsequent health status in at-risk populations, and 2) further research needs to be conducted in order to learn more about the relationships between HIV infection and rural living and the needs of people who live in such situations. With this knowledge, appropriate healthcare services can be developed and implemented to enhance the well-being and quality of life for individuals, families, and communities in this age of HIV/AIDS pandemic.
