Provision of HIV testing services and its impact on the HIV positivity rate in the public health sector in KwaZulu-Natal: a ten-year review.

South Africa has been rated as having the most severe HIV epidemic in the world since it has one of the largest populations of people living with HIV (PLHIV). KwaZulu-Natal (KZN) is the epicentre of the HIV epidemic. The HIV test and treat services in the public health sector are critical to managing the epidemic and responding to the increase in HIV infections.

Cost-effectiveness of staff and workload profiles in retaining patients on antiretroviral therapy in KwaZulu-Natal, South Africa.

Background: There is paucity of information on the cost-effectiveness of delivery strategies to retain patients on antiretroviral therapy (ART) and this study tries to fill this gap.

Methods: The analysis is based on a representative sample of 2835 patients attending 32 ART sites in KwaZulu-Natal (KZN), South Africa. Extended Cox regression and Kaplan Meier were used to estimate the transition probabilities to remain on ART among patients who attended sites with different staff and workload profiles.

The preparedness of emergency medical services against occupationally acquired communicable diseases in the prehospital environment in South Africa.

Background: Emergency medical care is performed in an uncontrolled environment and involves invasive procedures and life support measures. The performance of these duties places emergency care practitioners (ECPs) at risk of occupationally acquired injuries and communicable diseases. Although legislative guidelines exist for the protection of healthcare workers, little is known about the protective measures available for and utilised by ECPs in the pre-hospital environment in South Africa.

Changing patterns of under- and over-nutrition in South African children-future risks of non-communicable diseases.

Under- and over-nutrition in children in KwaZulu-Natal, South Africa was investigated comparing data collected from primary school children in a rural district (643 children aged 8-11 years in 1994) with secondary data from the National Schools Study (16,179 children, 4-11 years in 1994), the Vitamin A Consultative Group Study (408 children, 2-5 years in 1994) and the Income Dynamics Study (1,593 children, 2-11 years in 1998). Stunting and wasting (WHO/NCHS guidelines) and overweight and obesity (International Obesity Task Force guidelines) were retrospectively analysed from these studies and compared in the children aged 4-5 and 8-11 years. There was moderate stunting in 10-25%, wasting in 1-6%, 5-24% were overweight and 1-10% obese.

The effects of a systematically developed photo-novella on knowledge, attitudes, communication and behavioural intentions with respect to sexually transmitted infections among secondary school learners in South Africa.

A pre-post test follow-up design was used to test the effects of a systematically developed photo-novella (Laduma) on knowledge, attitudes, communication and behavioural intentions with respect to sexually transmitted infections, after a single reading by 1168 secondary school learners in South Africa. The reading resulted in an increase in knowledge on the spread of sexually transmitted infections (STIs), change in attitude to condom use and towards people with STIs and/or HIV/AIDS, as well as increased intention to practice safe sex. Laduma did not influence communication about sexually transmitted infections and reported sexual behaviour and condom use.
