    Associations between economic preferences and behavioural health intentions among young adults living in an informal settlement
    (University of the Witwatersrand, Johannesburg, 2023-03) Andrady, Wayne Jude; Booysen, Frikkie
    The emergence of non-communicable diseases in South Africa, most notably among the urban poor, is resulting in an increased burden of diseases. Since NCDs can develop in distinct periods of the life course, post-adolescence-intentions to engage in health behaviours need to be investigated. Furthermore, there is consistent evidence that health behaviours are associated with economic preferences. Yet, it is unclear whether economic preferences are also associated with behavioural health intentions. Objectives: The study aims to examine how risk-taking and patience are associated with behavioural health intentions among young adults in a poor informal urban settlement in South Africa. The study also explores whether there are gender differences in behavioural health intentions and whether these economic preferences contribute to gender gaps in behavioural health intentions. Data and Methods: The study utilized secondary survey data collected from a sample of 240 young adults using a structured questionnaire. The study collected data on behavioural intentions for seven health- protective and health-harming behaviours. Risk-taking and patience are measured using qualitative, quantitative and combined measures from the Global Preference Survey. Ordered probit and seemingly unrelated regression models were estimated and t-tests were employed to quantify gender gaps, followed by the Blinder-Oaxaca decomposition analysis. Findings The study reveals that economic preferences have a moderate association with behavioural health intentions among young adults. However, these results seem contradictory to priori expectations and further research is required. Our findings emphasize the importance of recognizing and addressing the limitations associated with imperfect measures of economic preferences when investigating their association with health behavioural intentions

    HIV/AIDS and Educational Attainment Among South African Children and Adolescents
    (University of the Witwatersrand, Johannesburg, 2023-06) Havley, Simon; Booysen, Frikkie
    This study examines the effects of HIV-infection, antiretroviral treatment exposure and viral load suppression on indicators of educational attainment among children and adolescents of school-going age in South Africa using data from a nationally representative survey and linked biomedical information. This study employs propensity score matching-based approaches to examine the effects of HIV-related indicators on educational attainment overall and within each gender. This study also uses decomposition analyses to examine the contribution of HIV- related indicators to gender gaps in educational attainment, and to identify factors contributing to differences in the impacts of HIV-related factors on educational attainment of females specifically. It is found that HIV-positive status has a significant impact on the likelihood of school attendance, absenteeism, and being old for one’s grade. This is the case for all children and adolescents of school-going age. These effects are statistically significant for girls but not for boys. The study also finds that HIV-related factors contribute to gender gaps in school attendance, and that these gaps are observed in all tiers of the HIV treatment cascade. These results indicate that HIV-related factors impact disproportionately and negatively on educational attainment for girls. Further research on the gendered nature of the impact of HIV on education in South Africa is encouraged, as is the design of health and education policies that specifically target improved education outcomes among HIV-positive girls.
