HIV and AIDS prevention: knowledge, attitudes, practices and health literacy of older persons in the Western Cape and KwaZulu-Natal Provinces, South Africa and in Lesotho.

BACKGROUND: Population ageing and access to anti-retroviral therapies in South Africa have resulted in ageing of the HIV/AIDS epidemic, which has implications for policy, planning and practice. Impactful interventions on HIV/AIDS for older persons require knowledge on effects of the pandemic on this population. A study was undertaken to assess knowledge, attitudes, and practices (KAP) of HIV/AIDS, as well as health literacy (HL) level of a population aged ≥ 50 years. METHODS: A cross-sectional survey was conducted at three sites in South Africa and two sites in Lesotho with an educational intervention at the South African sites. At baseline, data were collected for assessment of KAP of HIV/AIDS and HL levels. The pre- and post-intervention comprised participants at South African sites being familiarised with the contents of a specially constructed HIV/AIDS educational booklet. Participants' KAP was reassessed six weeks later. A composite score of ≥ 75% was considered adequate KAP and an adequate HL level. RESULTS: The baseline survey comprised 1163 participants. The median age was 63 years (range 50-98 years); 70% were female, and 69% had ≤ 8 years' education. HL was inadequate in 56% and the KAP score was inadequate in 64%. A high KAP score was associated with female gender (AOR = 1.6, 95% CI = 1.2-2.1), age < 65 years (AOR = 1.9, 95% CI = 1.5-2.5) and education level (Primary school: AOR = 2.2; 95% CI = 1.4-3.4); (High school: AOR = 4.4; 95% CI = 2.7-7.0); (University/college: AOR = 9.6; 95% CI = 4.7-19.7). HL was positively associated with education but no association with age or gender. The educational intervention comprised 614 (69%) participants. KAP scores increased post intervention: 65.2% of participants had adequate knowledge, versus 36% pre-intervention. Overall, younger age, being female and higher education level were associated with having adequate knowledge about HIV/AIDS, both pre- and post-intervention. CONCLUSIONS: The study population had low HL, and KAP scores regarding HIV/AIDS were poor but improved following an educational intervention. A tailored educational programme can place older people centrally in the fight against the epidemic, even in the presence of low HL. Policy and educational programmes are indicated to meet the information needs of older persons, which are commensurate with the low HL level of a large section of that population.

Traditional health practitioners' perceptions, herbal treatment and management of HIV and related opportunistic infections.

BACKGROUND: In South Africa, traditional health practitioners' (THPs) explanatory frameworks concerning illness aetiologies are much researched. However there is a gap in the literature on how THPs understand HIV-related opportunistic infections (OIs), i.e. tuberculosis, candidiasis and herpes zoster. This study aimed to comprehend THPs' understandings of the aforementioned; to ascertain and better understand the treatment methods used by THPs for HIV and OIs, while also contributing to the documentation of South African medicinal plants for future conservation. METHODS: The study was conducted in two locations: Strand, Western Cape where THPs are trained and Mpoza village, Mount Frere, Eastern Cape from where medicinal plants are ordered or collected. Semi-structured interviews were conducted with 53 THPs of whom 36 were diviners (amagrirha: isangoma) and 17 herbalists (inyanga). THPs were selected through a non-probability "snowball" method. Data were analysed using a thematic content analysis approach. An ethnobotanical survey was conducted and plants used to manage HIV and OIs were collected. A complete set of voucher specimens was deposited at the University of the Western Cape Herbarium for identification. Plant names were checked and updated with Kew's online website http://www.theplantlist.org . RESULTS: THPs conceptualise the aetiology of HIV and OIs at two related levels. The first involves the immediate manifestation of the illness/condition because of a viral infection in the blood (HIV), the presence of bacteria in the lungs (tuberculosis), or weakened state of the body making it susceptible to OIs. The presence of OIs is indicative of the probable presence of HIV. The second level of causation affects the first, which includes pollution, changes in cultural sexual norms, witchcraft, environmental factors, and lack of adherence to ancestral rituals. THPs reported using 17 plants belonging to 12 families. Remedies included mixes of up to five plants. CONCLUSION: This study explored the THPs' perspectives on HIV and commonly associated OIs and their herbal treatment methods. THPs generally rely on biomedical diagnosis before treating a client. They also seek guidance from the ancestors for a particular diagnosis, the plants to use for a specific treatment, when to harvest, and how to administer herbal remedies.
