Determinants and treatment of hypertension in South Africans: The first demographic and health survey

Objectives: To identify the groups of patients with high prevalence and poor control of hypertension in South Africa. Methods: In the first national Demographic and Health Survey, 12 952 randomly selected South Africans, aged 15 years and older were surveyed. Trained interviewers completed questionnaires on socio-demographic characteristics, lifestyle and the management of hypertension. This cross-sectional survey also included blood pressure, height and weight measurements. Logistic regression analyses identified the determinants of hypertension and the treatment status in this dataset. Results: A high risk of hypertension was associated with less than tertiary education, older age groups, overweight and obese people, using alcohol in excess, and a family history of stroke and hypertension. Rural Africans had the lowest risk of hypertension, which was significantly higher in obese African women than in women with normal body mass index. Improved hypertension control was found in the wealthy, women, older persons, being Asian, and having medical insurance. Conclusions: Rural African people had lower hypertension prevalence rates than the other groups. The poorer, younger men, without health insurance had the worst level of hypertension control.

Tobacco use in South Africans during 1998: The first demographic and health survey

Objective To determine smoking patterns in South Africa, and to identify groups requiring culturally appropriate smoking cessation programmes. Methods A random sample of 13 826 people (415 years), was interviewed to identify tobacco use patterns and respiratory symptoms. Peak expiratory flow rates were measured. Multinomial regression analyses identified sociodemographic factors related to tobacco use, and the latter’s association with respiratory conditions. Results In 1998, 24.6% adults (44.2% of males and 11.0% of females) smoked regularly. Coloured women had a higher rate (39%) than African women (5.4%). About 24% of the regular smokers had attempted to quit, with only 9.9% succeeding. African women (13.2%) used smokeless tobacco more frequently than others. Of the nonsmokers 28% and 19% were exposed to environmental tobacco smoke in their homes and workplaces, respectively. The regression analysis showed that the demographic characteristics of light smokers (1–14 tobacco equivalents per day) and heavy smokers (>=15 tobacco equivalents per day) differed. Light smoking occurred significantly more frequently in the poorest, least educated and urban people. The relative risk for light smoking was 18 in Coloured women compared with African women. Heavy smoking occurred most frequently in the highest educated group. A dose–response was observed between the amount smoked and the presence of respiratory diseases. Conclusions Smoking in South Africa is decreasing and should continue with the recently passed tobacco control legislation. Culturally appropriate tobacco cessation programmes for the identified target groups need to be developed.

The ethics of corporate governance: A (South)African perspective

Purpose – The purpose of this paper is to review the developments in South African corporate governance since the end of apartheid, with a view to identifying themes and points of convergence and/or divergence with other models. Design/methodology/approach – The paper presents a critical review of South African corporate governance in the context of political and economic developments. Where relevant, aspects of corporate governance theory (in particular the stakeholder and shareholder debate) are considered in the South African context. Findings – South African corporate governance can be seen to broadly follow Anglo‐American examples with the notable exception of the stakeholder approach of the two King reports. This approach emphasises the responsibilities of companies to various stakeholders and encourages stakeholder engagement as an integral element of company strategy. There has not, however, been any substantial incorporation of stakeholder interests into formal corporate governance structures such as board structure and financial reporting. Practical implications – The ongoing consideration of corporate governance developments in South Africa is important for its continued development in the country and the region. Originality/value – A review of South African corporate governance is timely given the probable release of the third King report in 2009, together with new company legislation.

A commentary on the global position of South African accounting research

The South African designation of Chartered Accountant is comparable to similar designations in most developed countries. However, the research outputs of Accountancy academics in South Africa seem to lag far behind those of their counterparts abroad. This article discusses the results of several inquiries into the status of South African Accounting research in a global context, and identifies several reasons and possible remedies for low research output.

A humanistic approach to South African accounting education

Humanistic psychologist Carl Rogers made a distinction between traditional approaches and humanistic `learner-centred\' approaches to education. The traditional approach holds that educators impart their knowledge to willing and able recipients; whereas the humanistic approach holds that educators act as facilitators who assist learners in their learning processes. As a learning theory, humanism refers to the belief in the innate ability of humans to learn, and the creation of an environment in which students are given `Freedom to Learn\'. South African accounting education has, by and large, followed the traditional approach rather than the humanistic approach. This article attempts to expand on the existing references to a humanistic approach through a more detailed exposition and application of the educational theory of Carl Rogers in the context of South African accounting education. The prospects of a humanistic approach in accounting education are then discussed and some practical strategies provided in relation to a specific third-year undergraduate accounting unit offered in South Africa.

Differences between Black and White South Africans in product failure attributions, anger and complaint behaviour

The purpose of this research is to extend an understanding of how Black and White South African consumers' causal attributions for major household appliance performance failures impact on their anger and subsequent complaint behaviour. A survey was administered to Black and White South African consumers who were dissatisfied with the performance of a major household appliance item. Respondents resided in a major metropolitan area. The findings showed that, compared to Whites, the Black South Africans felt a low but significantly higher external locus of causality and lower control, and experienced a higher level of anger regarding product failure. The level of anger determined the decision to take complaint action, but racial group determined the type of action taken. Blacks complained more actively to retailers and engaged more in private complaint action than Whites. These findings may show that Black South Africans are developing a more individualistic orientation as consumers. Therefore, researchers should consider the effect of cultural swapping when researching consumer behaviour in multi-cultural countries. Implications for retailers in terms of complaint handling are indicated.

Further evidence for linkage of Gilles de la Tourette syndrome (GTS) susceptibility loci on chromosomes 2p11, 8q22 and 11q23-24 in South African Afrikaners

Utilizing DNA samples from 91 Afrikaner nuclear families with one or more affected children, five genomic regions on chromosomes 2p, 8q, 11q, 20q, and 21q that gave evidence for association with GTS in previous case-control association studies were investigated for linkage and association with GTS. Highly polymorphic markers with mean heterozygosity of 0.77 were typed and resulting genotypes evaluated using single marker transmission disequilibrium (TDT), single marker haplotype relative risk (HRR), and multi-marker "extended" TDT and HRR methods. Single marker TDT analysis showed evidence for linkage or association, with p-values near 0.05, for markers D2S139, GATA28F12, and D11S1377 on chromosomes 2p11, 8q22 and 11q23-24, respectively. Extended, two-locus TDT and HRR analysis provided further evidence for linkage or association on chromosome 2 with p-values of 0.007 and 0.025, and chromosome 8 with p-values of 0.059 and 0.013, respectively. These results provide important additional evidence for the location of GTS susceptibility loci.
