This collection includes content from the MRC/Wits Rural Public Health and Health Transitions Research Unit (Agincourt) which has been operating the Agincourt health and demographic surveillance system since 1992. Work has evolved since then into a robust research infrastructure supporting advanced community-based research with studies ranging from the biomedical to the ethnographic, making rural voices heard.

    Associations of father and adult male presence with first pregnancy and HIV infection: Longitudinal evidence from adolescent girls and young women in rural South Africa (HPTN 068)
    (Springer, 2021-01) Albert, Lisa M; Edwards, Jess; Pence, Brian; Hills, Susan; Kahn, Kathleen; Gómez‑Olivé, F. Xavier; Wagner, Ryan G; Twine, Rhian; Pettifor, Audrey
    This study, a secondary analysis of the HPTN 068 randomized control trial, aimed to quantify the association of father and male presence with HIV incidence and first pregnancy among 2533 school-going adolescent girls and young women (AGYW) in rural South Africa participating in the trial between March 2011 and April 2017. Participants’ ages ranged from 13–20 years at study enrollment and 17–25 at the post-intervention visit. HIV and pregnancy incidence rates were calculated for each level of the exposure variables using Poisson regression, adjusted for age using restricted quadratic spline variables, and, in the case of pregnancy, also adjusted for whether the household received a social grant. Our study found that AGYW whose fathers were deceased and adult males were absent from the household were most at risk for incidence of first pregnancy and HIV (pregnancy: aIRR = 1.30, Wald 95% CI 1.05, 1.61, Wald chi-square p = 0.016; HIV: aIRR = 1.27, Wald 95% CI 0.84, 1.91, Wald chi-square p = 0.263) as compared to AGYW whose biological fathers resided with them. For AGYW whose fathers were deceased, having other adult males present as household members seemed to attenuate the incidence (pregnancy: aIRR = 0.92, Wald 95% CI 0.74, 1.15, Wald chi-square p = 0.462; HIV: aIRR = 0.90, Wald 95% CI 0.58, 1.39, Wald chi-square p = 0.623) such that it was similar, and therefore not statistically significantly different, to AGYW whose fathers were present in the household.

    Exploring the perception of and attitude towards preconception care service provision and utilisation in a South Western Nigerian community – a qualitative study
    (School of Public Health, University of the Witwatersrand, Johannesburg, South Africa, 2021-02) Ojifinni, Oludoyinmola O.; Munyewende, Pascalia O.; Ibisomi, Latifat
    Background: Hospital-based, quantitative studies in Nigeria show low levels of knowledge and use of preconception care (PCC) services. This study explored the perception of and attitude towards PCC in a southwestern Nigerian community qualitatively. Data Source and Methods: Focus group discussions (FGDs) were held with 57 purposively selected adult women and men and key informant interviews (KIIs) with one female and one male community leader in Ibadan North Local Government Area, Oyo State, Nigeria in 2018. The FGDs and KIIs held within the community were digitally recorded, transcribed verbatim and analysed thematically. Results: Participants placed PCC in the context of marriage, describing its importance for addressing effects of adverse exposures on pregnancy and ensuring positive pregnancy outcomes. Conclusion: Barriers to PCC uptake mentioned included lack of awareness and prohibitive service costs. Expressing their willingness to use and promote PCC use, they stated the need to ensure PCC uptake through improved awareness at the community level.

    The global cost of epilepsy: A systematic review and extropolation
    (Wiley Online LIbrary, 2022-02-22) Begley, Charles; Wagner, Ryan G; Abraham, Annette; Beghi, Ettore; Newton, Charles; Kwon, Churl-Su; Labiner, David; Winkler, Andrea S
    "Objective Global action for epilepsy requires information on the cost of epilepsy, which is currently unknown for most countries and regions of the world. To address this knowledge gap, the International League Against Epilepsy Commission on Epidemiology formed the Global Cost of Epilepsy Task Force. Methods We completed a systematic search of the epilepsy cost-of-illness literature and identified studies that provided a comprehensive set of direct health care and/or indirect costs, followed standard methods of case identification and cost estimation, and used data on a representative population or subpopulation of people with epilepsy. Country-specific costs per person with epilepsy were extracted and adjusted to generate an average cost per person in 2019 US dollars. For countries with no cost data, estimates were imputed based on average costs per person of similar income countries with data. Per person costs for each country were then applied to data on the prevalence of epilepsy from the Global Burden of Disease collaboration adjusted for the treatment gap. Results One hundred one cost-of-illness studies were included in the direct health care cost database, 74 from North America or Western Europe. Thirteen studies were used in the indirect cost database, eight from North America or Western Europe. The average annual cost per person with epilepsy in 2019 ranged from $204 in low-income countries to $11 432 in high-income countries based on this highly skewed database. The total cost of epilepsy, applying per person costs to the estimated 52.51 million people in the world with epilepsy and adjusting for the treatment gap, was $119.27 billion. Significance Based on a summary and extrapolations of this limited database, the global cost of epilepsy is substantial and highly concentrated in countries with well-developed health care systems, higher wages and income, limited treatment gaps, and a relatively small percentage of the epilepsy population."
