Alcohol intake and cardiovascular function of black South Africans : a 5-year prospective study / Mandlenkosi Caswell Zatu

Zatu, Mandlenkosi Caswell January 2015 (has links)
Motivation Alcohol consumption is one of the major risk factors of cardiovascular disease (CVD). Excessive alcohol drinking is the fifth leading cause of death worldwide and the prevalence of alcohol abuse continues to increase especially in low-income areas of sub-Saharan Africa. The alarming rate of urbanisation seems to be the driving force for excessive alcohol intake in the developing world. In addition to its influence on CVD, heavy drinking also results in a number of non-cardiovascular consequences that include injury, risky sexual behaviour, violent crime and family dysfunction among black South Africans, contributing to high mortality. Moreover, the highest number of individuals with human immunodeficiency virus (HIV) infection in South Africa is partly attributable to high intake of alcohol. HIV remains a major concern in South Africa with significant funding diverted to address the pandemic. The continued increases in mortality from preventable outcomes such as stroke, myocardial infarction and renal failure are largely due to urbanisation, poverty and dysfunctional health systems working with limited budgets. These are some of the factors requiring in-depth study of the scientific aspects of alcohol intake in South Africa. Although there is enough evidence that links excessive drinking with hypertension and CVD, the markers of alcohol intake – self reporting of alcohol, gamma-glutamyltransferase (GGT) and carbohydrate deficient transferrin – are still not specific enough to isolate other confounding factors in the association of alcohol intake with CVD. The markers of alcohol that independently predict CVD and mortality need to be explored. Finally, the severe lack of longitudinal investigations on alcohol-related hypertension development and total mortality in black South Africans has compromised the early identification of risk factors associated with these outcomes. This study will therefore attempt to address the limited availability of longitudinal studies and stimulate interest for continued investigation. Aim The aim of this study was to investigate whether alcohol intake of black South Africans is related to specific measures of cardiovascular function (change in blood pressure (BP), hypertension development) and mortality over a period of 5 years. Methodology This study was based on the international Prospective Urban and Rural Epidemiology (PURE) study which includes 26 countries, investigating the cause and development of cardiovascular risk factors in low, middle and high income countries. This South African leg of the PURE study started in 2005 in which the baseline data was collected from 2021 black South Africans from rural and urban areas in Ikageng, Ganyesa and Tlakgameng in the North West Province. Eleven participants presented with missing data, leaving 2010 participants with complete datasets at baseline. However, data from these 11 participants was useful, especially for Chapter 4. All participants gave informed consent and the Ethics committee of the North-West University (Potchefstroom Campus) approved the study. The follow-up data collection was done in 2010. General health questionnaires, anthropometric measurements, lipid profiles and cardiovascular measurements were taken both at baseline and follow-up using appropriate methods. We also collected blood samples and performed biochemical analyses for lipid markers, liver enzymes, inflammatory markers and percentage carbohydrate deficient transferrin (%CDT). Finally, we obtained data on cardiovascular and non-cardiovascular mortality through verbal autopsy and death certificates. We made use of analysis of variance (ANOVA) and Chi-square tests to compare means and proportions, respectively. We used dependent t-tests and the McNemar test to compare baseline and follow-up variables. Furthermore, we employed single and partial linear regression analyses to correlate alcohol markers with each other and with the cardiovascular measures. Multiple regression analyses were used to correlate dependent variables in the study with various independent variables as required. Finally, we employed multivariable-adjusted Cox regression analyses to assess the association of the selected alcohol markers with mortality while adjusting for several independent variables. Results and Conclusions of each manuscript - With the first research article (Chapter 4), we aimed to compare self-reported alcohol intake estimates with GGT and %CDT, considering their relationship with percentage change in brachial blood pressure (BP) and central systolic blood pressure (cSBP) over 5 years. The results indicated that only self-reported alcohol intake independently predicted % change in brachial BP and cSBP. This was not found for the biochemical markers GGT and %CDT. Self-reported alcohol intake seems to be an important measure to implement by health systems in low income areas of sub-Saharan Africa, where honest reporting is expected. - Given the likely presence of high GGT levels in both alcohol consumption and non-alcoholic fatty liver disease (NAFLD), the second manuscript (Chapter 5) aimed to compare the cardiovascular and metabolic characteristics of excessive alcohol users and individuals with suspected NAFLD (confirmed with self-report, GGT and %CDT). We found that different sex and cardiometabolic profiles characterised excessive alcohol users and individuals suspected with NAFLD. Lean body mass and male sex were the dominant characteristics in excessive alcohol use while the NAFLD group had a dysmetabolic profile with obese women making up the higher proportion of this group. In excessive alcohol users systolic blood pressure and pulse pressure were independently associated with high-density lipoprotein cholesterol. Diastolic blood pressure showed a significant correlation with waist circumference. These disparate profiles may guide healthcare practitioners in primary healthcare clinics to identify individuals with elevated GGT levels who may suffer from NAFLD or alcohol overuse. These results emphasise the importance of modifiable risk factors as the main contributors to CVD and that lifestyle change should be the main focus in developing countries such as South Africa. - The third manuscript (Chapter 6) aimed to determine the measure of alcohol intake (selfreported alcohol intake, GGT and %CDT) that related best with hypertension development, cardiovascular and all-cause mortality over 5 years in the same population of black South Africans. We found that GGT was the only independent predictor of hypertension development, cardiovascular as well as all-cause mortality. Moreover, self-reporting of alcohol intake predicted incident hypertension, confirming our findings from Chapter 4. The third marker, %CDT, a highly specific marker of alcohol intake, was not related with any outcome variable, perhaps due to its low sensitivity. Although self-reported alcohol intake is useful in low-resource primary healthcare settings, measurement of GGT is encouraged due to its predictive value for hypertension and mortality. GGT represents alcohol intake, non-alcoholic steatohepatitis and obesity - all known to have severe cardiovascular consequences. Discussion and Conclusions Excessive alcohol intake remains a major concern in the development of hypertension, CVD and premature death in sub-Saharan Africa. Despite their weaknesses such as bias and nonspecificity, self-reporting of alcohol consumption and GGT emerged as reliable alcohol markers that independently predicted 5-year change in BP, hypertension development and total mortality in this population. Serum %CDT did not show any association with the mentioned cardiovascular markers. Finally, we were also able to show that black South Africans with suspected NAFLD (i.e. with high GGT levels who do not consume alcohol) are typically obese women, whereas lean men were more likely to have high alcohol consumption. Further prospective investigations are encouraged regarding (a) these mentioned associations, as well as (b) other self-reporting estimates such as quantity and frequency of drinking and (c) the use of %CDT as a highly specific marker of alcohol intake. The simultaneous presence of HIV infection in alcohol abuse in this population also warrants further investigation. / PhD (Physiology), North-West University, Potchefstroom Campus, 2015

English as a medium of instruction: the relationship between motivation and English second language proficiency

Madileng, Mary Mmatsatsi 06 1900 (has links)
In order to research the limited English proficiency of First Year National Intermediate Certificate students at the Further Education and Training College of Ekurhuleni West, the researcher investigated various motivation variables, namely: * socio-psychological factors * learner factors * parental involvement and * contextual factors related to the influence of the school and classroom A review of literature and empirical research methods were used to this effect. The literature review revealed that instrumental and integrative motivation, self-determination and goal orientedness, parental support and school and classroom context factors contributed to the development of ESL proficiency. A motivation questionnaire and an English proficiency test were administered to the participants. The results indicated no significant relationship between the learner's level of ESL proficiency and motivation variables. These findings form the basis for recommending specific guidelines for possible directions for future research. / Linguistics / M.A. (Specialisation in Applied Linguistics)

Behoeftebepaling ten opsigte van die bediening van die Nederduitse Gereformeerde Kerk aan lidmate met 'n laer sosio-ekonomiese status

Robb, Jacobus Petrus. 15 June 1994 (has links)
Text in Afrikaans / According to Kerkspieel III (s.a. :20) a tendency has been observed in the Dutch Reformed Church during the last decade, to aim its ministry mainly at members of ·the higher professional careers, consequently failing to reach people from the lower blue collar occupations. This tendency has caused a rise in membership of the higher professional career group, from 27.43% to 36.90%; and a consequent drop in that of the lower blue collar occupations, from 28.74% to·20.21% during this time. Is it possible for members of the Dutch Reformed Church, belonging to a -lower socio-economic status (S.E.S.), to have certain needs which ~he church cannot satisfy? The purpose of· this study is to investigate the issue of church members with a lower S.E.S., having peculiar needs which are not satisfied by the ministry of the Dutch Reformed Church. Ellisras-Wes, are atively young industrial congregation. _ It was revealed from the literature· study that churches or denominations in general are inclined to feel an affinity with a limited section of society. Protestant Churches in particular are inclined to pay special attention to ·certain S.E.S. groups. Although certain differences regarding patterns of conduct and attitude have been. identified among various S.E.S. groups,. there was no considerable indications that a correlation exists between members' S.E.S. and needs. The perception that.people with a lower S.E.S. would be irreligious, uninvolved and disinterested, can therefore be rejected. Evidence to the contrary is that the religious experience of lower S.E.S. members is more genuine and traditional, while members with a higher S.E.S. tend to have a critical attitude against the Bible and church-doctrine. Even atheism occurs to a greater extent within this group. This tendency will continue until such time as the Dutch Reformed Church acknowledges its deficiency in this respect and reach to lower S.E.S groups. The church may consequently show a considerable growth. / Philosophy, Practical & Systematic Theology / D.Th. (Practical Theology)

The cross-cultural compatability of the 16 personality factor inventory (16PF)

Abrahams, Fatima 11 1900 (has links)
This study focused on the 16PF (SA 92), a personality questionnaire that was developed in the USA and adapted for South African conditions. The main aim of the study was to determine whether the scores of the 16PF are comparable in a cross-cultural setting in South Africa. The influence of age, language, socio-economic status and gender on the scores were also determined. The sample consisted of black, white, coloured, and Indian university students and were drawn from the University of Western Cape, University of Pretoria, University of DurbanWestville, and University of Natal. To achieve the aims outlined construct comparability studies and item comparability studies were conducted. In addition, descriptive statistics were also calculated to provide a general picture of the performance of the various sub-samples. A qualitative study was also conducted to determine some of the reasons for the occurrence of item incomparability of the racial sub-sample. The results showed that the racial variable had the greatest influence on the scores obtained. Problems existed with the construct and item comparability of the 16PF when the different race groups were compared. In addition, significant mean differences were also found on the majority of factors when the scores of the different race groups were compared. The results of the qualitative study showed that participants whose home language was not English or Afrikaans had difficulty in understanding many of the words and the construction of sentences contained in the 16PF. The implications of using the 16PF in South Africa, with its multicultural population was outlined, taking the new labour legislation pertaining to selection into consideration. Finally, a number of options for test users, and users of the 16PF in particular were presented. / Industrial and Organisational Psychology / D.Com. (Industrial Psychology)

Hoe gee studente by 'n werkersklasskool in 'n werkersklaswoonbuurt gestalte aan hul opvoedkundige aspirasies? 'n Gevallestudie van vyf graad 11-studente

Fillies, Henry 12 1900 (has links)
Thesis (MEd)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: The shaping of students. educational aspirations in their school and neighbourhood context is a complex process of confluence, and largely depends on their context-specific perceptions and conceptualisation. From a sociological perspective, this study focuses on how high-school students at a working-class school in a working-class neighbourhood shape their educational aspirations amidst their particular community dynamics. The study uses the analytical lens of space in order to investigate the underlying relationship between youth development and the youth.s educational aspirations in their neighbourhood context. It emphasises students. life experiences in two spaces, namely their residential space (the neighbourhood) and their institutional space (the school). This is an important focus in order to explore the dynamic relationship between students. spatial living dynamics and how they navigate within these to shape their educational aspirations. The study focuses on how the students experience the neighbourhood and school in relation to their educational aspirations, and how these aspects manifest in the shaping of their aspirations. Also key to the study is the students. prior socialisation processes with regard to their educational aspirations. The study.s primary point of departure is that there is a unique relationship between these students. living contexts and how they construct and position their educational aspirations within these contexts. The study belongs within the qualitative interpretative paradigm, as I attempt to describe and understand how these students consciously draw from practices and interactions in their living contexts to shape their educational aspirations. Qualitative research instruments, such as field notes, participatory and non-participatory observations as well as formal and informal interviews, were used to answer the research question and achieve the research objectives of the thesis. The findings are presented in narrative format according to relevant themes, and are also analysed on a narrative basis. The research shows how the students . based on their own resources, networks and interactions as well as their own agency . position themselves in relation to their educational aspirations in order to shape their aspirations. In this way, the study reveals how the participating students dualistically draw from the practices of both their living spaces . school as well as neighbourhood . in order to give content to their educational aspirations; how they navigate the shaping of their educational aspirations .in parallel., as it were, in line with both the aforementioned living contexts. / AFRIKAANSE OPSOMMING: Studente se opvoedkundige-aspirasievorming in hul skool- en woonbuurtkonteks is 'n komplekse proses van samevloeiing, en hang grootliks van hul konteksspesifieke opvattings en konseptualisering af. Uit 'n sosiologiese perspektief konsentreer hierdie studie op hoe hoërskoolstudente by 'n werkersklasskool in 'n werkersklaswoonbuurt aan hul opvoedkundige aspirasies gestalte gee te midde van hul besondere gemeenskapsdinamiek. Die studie gebruik die analitiese lens van ruimte ten einde ondersoek in te stel na die onderliggende verwantskap tussen jeugwording en die jongmense se opvoedkundige aspirasies in hul woonbuurtkonteks. Die klem val op studente se lewenservarings in twee ruimtes, naamlik hul omgewingsruimte (die woonbuurt) en hul institusionele ruimte (die skool). Dit is 'n belangrike fokuspunt ten einde die dinamiese verwantskap te ondersoek tussen studente se ruimtelike leefdinamiek en hoe hulle daarin hul weg baan ten einde aan hul opvoedkundige aspirasies gestalte te gee. Die studie konsentreer op hoe die studente die woonbuurt en skool met betrekking tot hul opvoedkundige aspirasies beleef, en hoe hierdie aspekte in hul aspirasievormingsprosesse na vore kom. Nog 'n belangrike faktor in die studie is die studente se vorige sosialiseringsprosesse met betrekking tot hul opvoedkundige aspirasies. Die hoofuitgangspunt van die studie is dat daar 'n unieke verwantskap bestaan tussen hierdie studente se leefkontekste en hoe hulle hul opvoedkundige aspirasies daarin konstrueer en plaas. Die studie hoort tuis binne die kwalitatief-vertolkende paradigma, aangesien ek probeer beskryf en verstaan hoe hierdie studente op beredeneerde wyse uit praktyke en wisselwerkings in hul leefkontekste put om hul opvoedkundige aspirasies te vorm. Kwalitatiewe navorsingsinstrumente soos veldnotas, deelnemende en niedeelnemende waarnemings sowel as formele en informele onderhoude is gebruik om die navorsingsvraag te beantwoord en die navorsingsdoelwitte van die tesis te bereik. Die bevindings word in 'n narratiewe vorm aan die hand van tersaaklike temas aangebied en ook op 'n narratiewe grondslag ontleed. Die navorsing toon hoe die studente hulle - op grond van hul eie bronne, netwerke en wisselwerking sowel as hul eie agentskap - in verhouding tot hul opvoedkundige aspirasies plaas ten einde daaraan gestalte te gee. Sodoende onthul die studie hoe die deelnemerstudente op dualistiese wyse uit die praktyke van albei hul leefruimtes - skool en woonbuurt - put om hul opvoedkundige aspirasies te vorm; hoe hulle hul opvoedkundige-aspirasievorming as't ware 'parallel' in pas met albei voormelde twee leefkontekste navigeer.

Lone parenting, socioeconomic conditions and severe ill-health : longitudinal register-based studies

Ringbäck Weitoft, Gunilla January 2003 (has links)
The general aims of this dissertation are to analyse how family situation, and especially lone parenting, influence health and life chances in Sweden and the extent to which possible relations are influenced by socioeconomic circumstances and health selection. In two population-based cohort studies we analysed overall and cause-specific mortality (1991-95), and also severe morbidity (1991-94) from different causes among lone mothers in comparison with mothers with partners. Information on the mothers was obtained from the Swedish Population and Housing censuses of 1985 and 1990. The outcomes considered were death or utilisation of (overnight) hospital care, with data taken from population-based national health registers. In the analyses we adjusted for socioeconomic and demographic circumstances, such as socioeconomic status, country of birth, receipt of social-welfare benefit, and housing situation. To take health-selection effects into account, we adjusted for previous inpatient history (1987-90). Our findings suggest that lone motherhood entails health disadvantages with regard to mortality, severe morbidity and injury. Socioeconomic circumstances were found to play a major role in accounting for increased risks, but the risks are partly independent of both socioeconomic conditions and health selection into lone motherhood. In two further studies we analysed mortality (1991-98), severe morbidity and injury (1991-99), and also educational achievement (in 1998 at ages 24-25 of offspring), of children who had lived in lone-parent families in comparison with children in two-parent families. We mainly used data from the Swedish censuses and national health-data registers. Living in a lone parent family was found to be associated with increased risks of a variety of unfavourable outcomes: psychiatric disease, suicide/suicide attempt, injury, addiction, and low educational attainment. Relatively poor educational performance and also health disadvantages are explicable to a large extent by socioeconomic conditions, especially a lack of economic resources (as measured here by receipt of social-welfare benefit and having rented accommodation). Educational achievement among children varies with cause of lone parenthood, with the best prospects found among the children of widows/widowers. In a fifth study we analysed mortality from different causes (1991-2000) among lone fathers (fathers with and without custody of their children) and childless men (with and without partners) in comparison with cohabiting fathers with children in the household. For this purpose we linked information from the Swedish censuses of 1985 and 1990 to Sweden’s Multi-Generation Register (which contains information about all known biological relations between children and parents). Lone non-custodial fathers and lone childless men suffer from the most pronounced elevated risks, especially of death from injury or addiction, but also from all-cause mortality and death from ischaemic heart disease. Being a lone custodial father also seems to entail an increased mortality risk, although generally to a much lesser degree, and not for all outcomes studied. The elevated risks for all subgroups fell when variables assumed to control health selection and socioeconomic circumstances were introduced into the initial regression model employed. However, even following adjustments, significantly increased risks, albeit greatly attenuated, remained in all the subgroups investigated.

AIM: To evaluate the prevalence of orthodontic problems and quality of life in relation to orthodontic problems among adolescent children in the city of Chennai, India. OBJECTIVES: To analyze the differences in the need for orthodontic treatment among children in the public and private schools; to analyze the need for orthodontic treatment among the various socioeconomic groups; to evaluate the Quality of Life (QoL) among the children; to analyze the relationship between Quality of Life (QoL) and the need for orthodontic treatment. METHODS: 200 children participated in the study, out of which 100 were from the private school and 100 from the public school from the city of Chennai, India. Two sets of questionnaires were used for the study, one was filled by the children and the other was filled by the researchers and trained dental assistants after doing a thorough dental examination and asking questions from the participants. This was carried out according to the recommendations of WHO oral health assessment. Statistical data was collected, recorded and analyzed using the software SPSS 17.0 for Windows. RESULTS: The private school children had more orthodontic problems than the public school children (49% and 44% respectively). The need for Orthodontic Treatment was the highest in children under the rich category (56.4%), followed by the children under the poor category (45.3%) and is least among the children under the average category (44.4%). The Quality of Life was... [to full text] / TIKSLAS: Įvertinti ortodontinio problemas ir perspektyvas atsižvelgiant į ortodontinio problemas tarp paauglių vaikų mieste Chennai, Indija.
