Item Investigating knowledge, attitudes and perceptions of COVID-19 vaccines among young people in Soweto, South africa(2024) Muthoni, JeliothVaccination against SARS-CoV-2 is the most prominent strategy in the global fight against COVID-19. Studies continue to show that vaccines are one of the most dependable and cost-effective public health interventions available as they save life every year. However, World Health Organization (WHO) has identified vaccine hesitation as one of the primary threats to global health. Little is known, however, about the causes and nature of vaccine hesitancy in Africa. Moreover, in South Africa a significant drop of COVID-19 vaccine when it was rolled out the youth. The age group is of critical importance as they are becoming productive people who would be essential in the development of any country hence the need to protect them. Furthermore, understanding why youth are hesitant to get vaccinated is critical if we are to increase and sustain public demand for vaccination and preserve the tremendous achievements of vaccination programs on the continent. Unfortunately, there are limited studies that have investigated vaccine hesitancy among the youth populations and precisely looking at their knowledge, attitudes, and perceptions of the COVID-19 vaccine. Hence, the study aims to investigate knowledge, attitudes and perceptions of COVID-19 vaccine among young people in Soweto. The study employed a quantitative method, whereby closed ended questionnaires were administered using Redcap a very power tool for collecting data. Quantitative method was the best fit for the study for it accommodates a large sample size. SowetoThembelihle Health Demographic Surveillance System database was in the identification of the samples. STATA version 13.0 was used for statistical analysis. Out of a sample size of 380, the study recorded a 79.2% (301/380) hesitancy levels. The study population recorded to be knowledgeable on COVID-19 disease and vaccine. However, negative attitudes and perceptions based on the study participants responses in some important elements. The elements included ‘COVID-19 is a hoax’ (p=0.011), ‘I prefer to gain immunity by being sick rather than by having a vaccine ‘(p=0.000) and ‘COVID-19 vaccine has serious side effects’ (p=0.000) The study found out that infordemic has played a significant on the knowledge levels precisely among the youth. The study participants were well- informed, but they had poor attitudes and perception towards COVID-19 vaccine. These insights could help to reinforce national efforts to contain the pandemic across South Africa in particular Soweto and lessen other important consequences of the pandemic well-being.Item The historical development of the commemoration of the June 16, 1976 Soweto students' uprisings: a study of re-representation, commemoration and collective memory(2015-09-02) Hlongwane, Ali KhangelaSouth Africa’s post-apartheid era has, in a space of nearly two decades, experienced a massive memory boom manifest in a plethora of new memorials, monuments, museums and the renaming of streets, parks, dams and buildings. This memorialisation process is intrinsically linked to questions of power, struggles and contestation in the making and remaking of the South African nation. The questions of power, struggle and contestation manifest as a wave of debates on the place of history, collective memory, identity and social cohesion in the inception as well as the functioning of the various memorialisation projects in society. This thesis concludes that debates concerning the meaning(s) as well as the way in which the June 16, 1976 uprisings have been memorialized, has been ongoing for the last three decades, and will continue into the future. This, as the findings bear out, is because the wider contextual situating of collective memory in its intangible and tangible form is intrinsically linked to complex experiences of the past; to ongoing experiments of a “nation” in the making, as well as pressing contemporary social challenges. The thesis also concludes that questions of power, struggle and contestation also manifest as a quest for relevant idioms and aesthetics of re-representation and memorialisation. Further, the thesis makes observations on the politics behind the assembling and the assembled archive as a toolkit in the fashioning of pasts and the making of collective memory. It reflects on the processes of re-thinking and remaking of the June 16, 1976 archive. These conclusions have been arrived at through an investigation of how the memory and meaning of the June 16, 1976 uprisings have been re-constructed, re-represented and fashioned over the last three decades. This was done by tracking and analysing the complex, diverse forms and character of its memorialisation. In the process, the study arrives at a conclusion that the memorialisation of the June 16, 1976 uprisings is characterised by the multiplicity of tangible and intangible features. The intangible features are characterised by forgetting, at one level, and are, on another level, animated through rituals of commemoration, counter- commemoration and memorial debate. The memorial debate on the uprisings is that of unity and diversity, division, contestation and counter-commemoration and essentially irresolvable, as history and memory are tools to address contemporary challenges.Item "Strategies for negotiating absent fathers among young people in Soweto, South Africa"(2014-07-22) Mdletshe, PrudenceThe family has been seen as playing an important part in children’s lives and their development. This is because families are seen to be the primary sources of individual development and thus should be seen as the building blocks of communities. Families serve as the main source of emotional, social and material support for most individuals. Thus, stable family environments are acknowledged to provide a fertile environment for children’s wellbeing and for them to grow up to be healthy responsible adults. Most South African children are raised by a single mother or by their maternal grandparents. Research conducted shows that South African Families face many challenges, and these challenges could be the source for high rates of absent fathers. Poverty has been identified to be one of the challenges that affect families in South Africa. Some researchers argue that poverty and inequality continue to undermine the family as an institution by reducing its effectiveness in realizing the roles of its members in society. Therefore poverty puts a burden on families and specifically on the main providers or ‘breadwinners’. Poverty in South Africa is mainly caused by lack of income, which is due to the high unemployment rates with little initiatives to reduce unemployment rates. The research was conducted qualitatively and specifically used narrative inquiry as a method of gathering data. In-depth, one-on-one narrative interviews were conducted in order to gain an in-depth understanding of the consequences of having an absent father and the strategies that young women adopted in order to deal with the consequences. Eight interviews with females aged from 18 – 21 years were conducted in Soweto. The findings reveal that the participants adopted both negative and positive coping strategies. Positive coping strategies include, creative writing, keeping a diary, maintaining a positive attitude, living a different life and speaking to others. Negative coping strategies included withdrawing from others, denial of a need of a father, self-blame, silence and defensive humor. More research is needed on how young people with absent fathers cope, paying into consideration issues of personality, culture and socialization.Item Learner mobility in Johannesburg-Soweto, South Africa : dimensions and determinants.(2012-03-07) De Kadt, Julia RuthMany South African school children are known to travel fairly long distances to school each day, in pursuit of the best possible educational opportunities in a schooling system that is known to vary greatly in quality. This thesis documents the dimensions and determinants of the daily, education-related travel of primary school aged children in Johannesburg-Soweto, South Africa. It uses data on a sample of 1428 children drawn from the Birth to Twenty cohort study to provide the first population-based data on the extent of learner mobility in contemporary urban South Africa. Learner mobility is measured in three different ways: firstly by the straight line distance between a child‘s home and his or her school; secondly by whether the child‘s school falls into the same geographical area as his or her home; and thirdly by whether the child attends his or her nearest, grade-appropriate school. The thesis provides clear evidence for extensive mobility using all three of these approaches to measurement. Over 25% of children were found to be travelling more than 5km each way to school and back on a daily basis. Almost 60% of children attended a school outside of the Census 2001 Sub-Place (roughly equivalent to a suburb) in which they lived, and fewer than 20% of children attended the grade-appropriate school nearest to their home. Counter to expectations, these figures were fairly stable over time, suggesting that educational mobility does not increase substantially as children age or transition to high school. Mobile children attended significantly more well-resourced and well-performing schools than their non-mobile peers, and the quality of schools attended increased with distance travelled. This substantiates the assumption that children and families make use of educational mobility to improve the quality of education that they are able to access. The analyses presented in the thesis suggest that two distinct patterns of mobility, with different determinants, are in use in the Johannesburg-Soweto area. The first relates primarily to travel from townships to historically advantaged schools in suburban Johannesburg, and typically requires substantial economic investment and extensive parental involvement. The second form of mobility operates at a more local level, and relates to children and families making choices between a number of relatively local schools. This form of mobility is less resource intensive. Children engaging in the first form of mobility were more likely to attend a particularly advantaged school, and to have a well-educated mother. By contrast, children engaged in the second form of mobility were more likely to live in a disadvantaged area, and come from households with moderate SES levels. iv The findings of this thesis provide important insights into the nature of school choice in South Africa, which have implications for educational policy, and the understanding of the nature of urban poverty as experienced by South African children. They also contribute to the international school choice literature, by providing novel information about the implications of relatively unregulated school choice for educational inequality and segregation in the South African context.Item Power, identity and agency at work in the popular economies of Soweto and Black Johannesburg.(2011-06-21) Krige, Paul Friedrich DetlevThis thesis investigates a number of economic and financial practices, processes, relationships, actors and institutions prevalent in the residential areas that form part of Johannesburg that is known as Soweto, all of which have in common the exchange, hoarding, spending and risking of cash money. It describes actual flows of monies between actors and through popular economic institutions which are embedded in social relations of friendship and kinship, neighbourhood life and socially constructed identities. Building on the anthropological literature that seeks to show how money flows carry meaning as well as having function, it inquires into the meanings such flows of money - between popular institutions and social groups and across social classes - have for a range of differently situated participants in the popular economies. It explores the ways in which institutions and practices within the popular economies are deployed by actors and groups so as to direct flows of monies into certain social networks and relationships while redirecting it away from others, highlighting the agency of actors and groups in relation to their position in the local and larger political economy. Employing elements of practice theory, as well as perspectives from both political economy and cultural economy approaches to everyday life, the thesis offers arguments about power, identity, agency and state sovereignty in the context of the history of Black Johannesburg under apartheid and makes a contribution to our understanding of the material and symbolic structures of everyday life in contemporary Soweto and Johannesburg.Item The characteristics of coronary artery disease in Soweto(2009-10-14T12:06:16Z) Ntyintyane, Lucas MthetheliIn many developing countries with advanced stages of the nutrition transition, the burden of coronary artery disease (CAD) has shifted from the rich to the poor. Much of this transition is caused by changes in lifestyle, in particular: dietary changes, an increase in weight and obesity, a decrease in physical activity, high levels of stress, and increasing tobacco and alcohol consumption. However, we have come to appreciate a prominent role for inflammation in atherosclerosis and its complications. Globalization, urbanization and Westernization of lifestyle will increase the socioeconomic burden posed by non-communicable diseases in middle-to-low-income countries. In South Africa, it is mainly the African population that is experiencing rapid urbanization and the nutrition transition. Reliable ischaemic heart disease (IHD) mortality data are not available for the black population of South Africa. The purpose of this thesis was: to determine whether factors such as inflammation, postprandial lipaemia and hyperglycaemia are important determinants in black patients with documented CAD (with no previous known history of diabetes mellitus) and their age matched controls; to assess the prevalence of the metabolic syndrome (MS) in black patients and abnormal glucose regulation on black patients with CAD; and to compare the metabolic syndrome prevalence rates using the National Cholesterol Education Program Adult Treatment III (NCEP: ATP III) and International Diabetes Federation (IDF) definitions. Socio-economic status, anthropometric data, glucometabolic variables, LDL particles and MS prevalence rates were measured using 40 patients and 20 controls. The patients were selected consecutively on the basis of a coronary angiogram performed during the preceding 24 months. All subjects had significant CAD, which was defined as more than 50% lesions in one or more major coronary arteries. Subjects with severe hypercholesterolaemia, defined as an untreated total cholesterol level over 7.5 mmol/l, were excluded from the study. Those subjects with diabetes mellitus or HIV/AIDS were excluded from the study. Paper 1, titled ‘Metabolic syndrome, undiagnosed diabetes mellitus and insulin resistance are highly prevalent in urbanized South African blacks with coronary artery disease’, demonstrated a high prevalence of MS in black patients with established CAD. To our knowledge, this is the first report from South Africa that documents the prevalence of the syndrome in black patients with CAD. Almost all of our patients had previously diagnosed hypertension (95%). The second most frequent risk factor was an elevated glucose concentration, which was seen in half the patient cohort. The importance of obesity, particularly abdominal obesity expressed as waist circumference (WC), is well documented as a risk factor for MS. An unexpected outcome of our study was that half of the patients had abnormal glucose regulation, despite the exclusion of previously diagnosed DM. This high prevalence was revealed by the oral glucose tolerance test (OGTT). Paper 2 compares the MS prevalence estimates, as defined by NCEP: ATP III and IDF, amongst urbanized black South Africans with CAD. The IDF proposed a single unifying definition in 2005, as different definitions used different sets of criteria; this led to confusing and inconsistent estimations of MS prevalence. The new definition standardizes the criteria for the diagnosis of MS and offers a fresh assessment of the syndrome. The main findings that arose from the study were that both definitions generated similar prevalence estimates of MS and the two definitions similarly identified the presence or absence of MS in more than 80% of patients. This study demonstrated that postprandial lipaemia and hyperglycemia were common in black CAD patients. Small dense LDL particles were highly associated with CAD. Fasting triglyceride concentrations was the strongest determinant. Prolonged exposure of the endothelium to TG–rich atherogenic remnant particles might be the reason why postprandial increases in TG account for greater CAD risk. Paper 3 assessed postprandial lipaemia in black CAD patients with and without metabolic syndrome. This study was the first to contribute information about postprandial lipaemia and hyperglycaemia in urbanized South African blacks with CAD. Fasting lipid profiles and postprandial responses to the oral fat load were similar in patients with and without metabolic syndrome. A possible explanation might be that because patients in both groups had established CAD, they exhibited some of the underlying features of CAD, such as atherogenic dyslipidaemia. The main finding was that postprandial lipaemia was common in black CAD patients, including patients with metabolic syndrome. Fasting triglycerides concentration was the strongest determinant. Small, dense LDL particles were highly associated with CAD. Paper 4 reports on the assessment of postprandial hyperglycaemia in urbanized blacks with and without CAD. Results showed that glucose AUC was significantly higher in the patients than in control subjects and 120 min. glucose, followed by 0 min. glucose concentration, were the strongest determinants of postprandial hyperglycaemia. Our study demonstrated that as glucose tolerance declined across the normal glucose tolerance, impaired glucose tolerance and diabetes mellitus categories, peak glucose concentrations occurred later in the oral glucose tolerance test; insulin and proinsulin responses were also delayed. A comparison between CAD patients and control subjects drawn from the same ethnic population verified that abnormal glucose tolerance and insulin resistance were more prevalent in the patients with CAD. Paper 5 aimed at investigating whether carotid intima-media thickness (CIMT) is a predictor of CAD in South African black patients. The results showed that CIMT correlated with evidence of angiographically proven CAD. The findings of this study need to be considered within the context of its limitations, i.e. the low number of women and some bias towards only hospital referred CAD patients. It was not our intention to recruit more men than women, but because CAD is more prevalent in men, the majority of participants happened to be male. Performance of the OGTT and hyperinsulinaemic euglycaemic clamp technique is time consuming and requires considerable laboratory resources; therefore a relatively small number of patients and control subjects were studied. These limitations do not detract from the overall conclusions. Paper 6 evaluated markers of inflammation in black CAD patients, some of whom had MS. Leptin was the only marker that increased with additional MS criteria. Elevated hs- CRP concentrations indicated an inflammatory state in CAD patients. Association of leptin with BMI, waist circumference (WC) and hs-CRP revealed a close link with MS, obesity and inflammation in urban black South African CAD patients. Paper 7 investigated the role of diet, socio-demographics and physical activity in a black South African population with CAD, compared to a healthy control group. While diet is known to be affected by urbanisation, differences in dietary intake were observed between the two urban groups, despite the similarity in their socio-demographic profile. The study highlighted the clinical relevance of MS, its likely impact on morbidity and mortality, and that its identification is, therefore, important in risk assessment of patients with CAD. Increasing recognition of MS is, therefore, an initial step in addressing the metabolic problems associated with the syndrome. Furthermore, it was shown that a preponderance of small, dense LDL particles was highly associated with CAD in black patients. Although CAD prevalence is still low at this stage, it is likely to increase rapidly among urban dwellers as they adopt a Western lifestyle.Item Oral health promotion in primary schools in Mofolo, Soweto(2008-10-23T08:52:06Z) Nakaziba-Ouma, Ann MarthaThe oral health knowledge, attitudes and practices of primary school children and teachers in Mofolo, Soweto were determined. The enabling and inhibiting factors for oral health promotion in the school environment were also assessed. The aim of the study was to determine if there was any difference in knowledge, attitudes and, practices in learners and teachers and their environment at schools that were exposed to a preventive, educational and tooth brushing programme and those learners and teachers that were not exposed to the programme. Three hundred and thirty-six primary school children six to twelve years of age from four primary schools in Mofolo, i.e. Itekeng, Vukani, Emsebeni and Tshedimoso completed questionnaires. Itekeng and Vukani primary schools were part of an existing tooth brushing, educative and preventive programme, and Emsebeni and Tshedimoso primary schools were not. Four focus group discussions (one from each school) were held with regard to knowledge of oral health and hygiene and the school environment. Seven teachers from two of the four schools and eight teachers from each of the other two schools attended the discussions. Both the learners and teachers at all the schools had little knowledge of dental care, like tooth brushing with fluoridated toothpaste. Frequency of brushing was poor. Most of the learners (61 percent) for the exposed learners and 50 perecent from the unexposed learners reported brushing their teeth once a day. Dietary habits of the learners revealed a high consumption of sugary snacks in between meals and sugar. Fifty-five percent of the exposed learners bought sweets and cakes and 56 percent of the unexposed learners bought fizzy drinks and fruit juices at school. Forty-six percent of the exposed and 58 percent of the unexposed learners said they took more than three spoons of sugar with their breakfast. . Utilisation of primary dental health services in the community by both teachers and learners was poor. More learners from the exposed schools (97 percent) than the unexposed (82 percent) had been to a dentist because they had a toothache. Only 1 percent from the exposed schools and 8 percent from the unexposed had been for a routine check up. Learners from both school categories and teachers had no knowledge of fluoride or benefits of water fluoridation. Over 98 percent of learners from both school categories had never heard of fluoride. The teachers believed it was their responsibility to teach learners and parents about oral health and showed willingness to participate in oral health promotion programmes. The main source of oral health knowledge among the learners was home. Several inhibiting factors to oral health promotion like poverty, lack of adequate oral health knowledge and poor school environment were identified in all the schools.There was no school policy regarding oral health promotion In conclusion, there were no significant differences in the reported knowledge, attitudes and practices between the learners and teachers from the two schools that were part of the preventive, educational and brushing programme and those from the other schools that were not part of the programme. This therefore shows that while preventive and educational programmes are an important component of oral health promotion, they are not adequate in changing knowledge, attitudes and oral health practices.Item Production of HIV/AIDS lessons in the entertainment-education television programme Tsha Tsha and their reception by HIV-positive men in Soweto-Johannesburg(2008-10-22T12:32:51Z) Ogenga, Fredrick OduorThis study aims to examine the production of HIV/AIDS lessons on Tsha Tsha Entertainment-Education and their reception by HIV-positive men in Soweto, and to find out whether this response impacts on their perception of their roles and responsibilities in HIV/AIDS. The rationale behind this study is that gender and HIV/AIDS has been critical in interventions aimed at combating the disease. Studies in South Africa on gender have revealed that versions of masculinity can be implicated in the increasing infection rates of HIV/AIDS making efforts to combat the disease problematic. A qualitative methodology is used. This method included interviews and focus group discussions. Five interviews were done with programme producers and researchers of Tsha Tsha to find out the major considerations in production. An average of seven HIV-positive men were exposed to 12 episodes of Tsha Tsha to find out their responses in six focus group discussions, and whether these indicated a changed perceptions in their roles and responsibilities in HIV/AIDS. Their responses were then examined under Bandura’s (1971) social learning theory and Hall’s (1977) encoding-decoding theory .This theories explain the considerations in the production of lessons in Tsha Tsha and how audiences respond to those lessons respectively. The findings reveal that audiences (HIV-positive) men identify with lessons around HIV-testing, disclosure, support and those that challenge stigma and masculinity in HIV/AIDS. Disclosure emerges as a major theme and is compared with sub themes of testing, stigma, masculinity and social support to form categories that are presented as the findings. While HIV-disclosure is seen as challenging HIV/AIDS stigma and masculinity, where men accept their condition, and take responsibility to continue occupying their space as men, E-E production can reinforce lessons around disclosure and other coping strategies to combat HIV/AIDS.Item HIV and Pre-eclampsia: Is there a connection?:(2007-02-23T12:08:07Z) Frank, Karlyn AnnesaObjective In view of recent suggestions that HIV infection may protect against pre-eclampsia, this study was done to estimate whether untreated HIV positive pregnant women have a lower rate of preeclampsia-eclampsia than HIV negative women. Methods Subjects for this study were pregnant women from Soweto, South Africa, who gave birth from March to December 2002 at midwife-run clinics or at the Chris Hani Baragwanath Hospital, and in whom the HIV status was known. A sample size calculation indicated that 2588 subjects would be required to show statistical significance at P<0.05 with a power of 80% for a reduction in the rate of preeclampsia from 8% to 5% with HIV seropositivity, assuming an HIV seroprevalence rate of 30%. Data collection was by record review from randomly selected patient files and birth registers. Results In the total sample of 2600 women, 1797 gave birth at the hospital and 803 at the midwife-run clinics. The HIV seroprevalence rate was 27.1%. Hypertension was found in 17.3% of women, with 5.3% having preeclampsia-eclampsia. The rates of preeclampsia-eclampsia were 5.2% in HIV negative and 5.7% in HIV positive women (P=0.61). CD4 count results were available for only 13 women (0.5%). Conclusion HIV seropositivity was not associated with any reduction in the risk of developing preeclampsia-eclampsia.
