Aims to contribute to a clearer understanding of the nature of current patterns of population change in the peri-urban region; conceptualized as a set of overlapping zones of net growth representing the product of four demographic processes (suburbanisation, counterurbanisation, population retention, centripetal migration). Considers three key aspects of peri-urban growth dynamics in the context of Adelaide's peri-urban region.

Bibliography: leaves 347-361. Presents results of 2 longitudinal studies investigating the oral health of older adults with dementia, using questionnaires and clinical inspections at baseline and one year. Groups studied were nursing home residents and those living in the community, with moderate to severe dementia or no dementia diagnosis. Caries experience was related to dementias severity and not to specific dementia diagnoses. Coronal and root caries experience was higher in dementia participants with moderate-severe dementia, the socio-economically disadvantaged, more functionally dependent, taking neuroleptic medications with high anticholinergic adverse effects, with eating and swallowing problems, were not attending the dentist, who needed assistance and were behaviourally difficult during oral hygiene care and whose carers were burdened.

In many countries, an enumeration of all household members remains the most important source of population statistics. According to Statistics South Africa, two population censuses and quite a few household surveys have taken place across the country. The quality of data recorded varies according to the operation. Despite great improvement in data collection and analysis capacities,some of the demographic data provided have not been assessed in terms of quality. The aim of this study was to ascertain the accuracy of demographic data on age and sex collected and the coverage during the population census 2001, General Household Surveys (2004 and 2007), Labour Force Surveys (2005 and 2007) and Community survey 2007 in South Africa. Two methods were applied to assess the quality of data. First, the direct method consists of checking the content and coverage (errors during enumeration, errors of exploitation, concordance in questionnaire). Second, the indirect method lies in the calculation of some indexes, age ratios,sex ratios, graphing of population pyramids and sex ratios curves. The indexes are Whipple’s index, Myer’s index and the Combined index of United Nations. Therefore, the main variables of interest are age, sex, place of residence and ethnic groups. Differentials in the quality according to declaration on age by gender, by ethnic group, by place of residence have been explored. This study has identified some variations in different indexes between 2001 and 2007 and has also evaluated the ethnic, gender and regional differentials. Comparison between indexes of each instrument has been done to measure some variations over years. Also, time-space comparisons were conducted across indexes of different instruments. The quality of data on age was better at national level compared to provincial level. Therefore, based on the measurements and patterns observed in the census and surveys data, the study has made some recommendations on the need for an integrated approach to reduce the gap and improve the quality of declarations on age and sex.

A number of mostly informal areas in Nelson Mandela Bay have experienced rapid expansion over the past decade or so. Census data available for these areas is outdated and does not provide enough information for local authorities to accurately plan for tasks such as service delivery management and resource allocation. In this dissertation, a GIS based demographic and Quality of Life study of informal settlements and previously disadvantaged areas within Nelson Mandela Bay is undertaken to address this issue. The study aims to integrate GIS technology into a demographic and Quality of Life survey to significantly improve the collection, analysis, interpretation, display and management of survey data and to provide the accurate and necessary updates required between census collections. Data relating to informal settlements were captured from aerial photographs and satellite imagery and demographic and Quality of Life data were collected from field surveys. The results demonstrated that the use of GIS technology provided more accurate information for demographic variables, including the number of dwellings, dwelling type, size of the population and population dynamics. A specific demographic trend observed through spatial analysis included the identification of backyard shacks predating formal structures in settlements. The analysis and representation of the Quality of Life field survey data in GIS demonstrated how residents' perceptions of problems and issues in their neighbourhoods are better interpreted, understood and managed when analyzed within a spatial context. This research concluded that GIS based demographic and QOL studies are vital for providing accurate social and spatial information for municipalities, particularly in urban environments of developing countries, and for providing the necessary updates to censuses occurring every ten years.

Dryland salinity occurs extensively throughout the Spicers Creek Catchment in central west New South Wales, Australia. The extent of dryland salinity in the Spicers Creek Catchment has severely altered the landscape, having major environmental implication. Large area of the catchments has experienced soil erosion resulting from the saline groundwater in the surface soil causing the destruction of clay and soil structure. The objective of this study was to use seismic refraction methods to map in detail a shear zone, which was associated with an area of major dryland salination. In particular, both the width of shear zone and the rock fabric within it were to be mapped with two both compressional (P) and shear (S) waves using a three-dimensional (3D) array of three- component (3C) receivers. The seismic data was recorded across a shear zone which is associated with salination in the Spicers Creek Catchment using the Australian National Seismic Imaging Resources (ANSIR) 360-trace system. Three-component (3C) geophones were used to record shear waves as well as compressional wave. An IVI minivibrator T-15000 was used as the main source of energy for the seismic survey. The results of the three-dimensional three-component seismic refraction surveys at the Spicers Creek Catchment show that the shear zone exhibit the seismic geophysical anomaly of a shear zone, existing as a narrow region with low seismic velocities and increased depth of weathering. A detailed analysis of the refractor seismic velocities and amplitude show a number of linear features parallel to and cross-cutting the shear zone. Linear features cut the shear zones at each site. They have been interpreted as a series of recent faults which act as discharge zone bringing saline groundwater to the surface.

BACKGROUND: Under-5 children in KwaZulu-Natal are highly exposed to dying before reaching five years of life. Studies have been conducted to understand the demographic and socioeconomic factors that influence under-5 mortality, both nationally and internationally, with some contradicting findings on the association between some socioeconomic and demographic factors and under-5 mortality. While some studies found child mortality to be significantly associated with rural geographical place of residence, the reverse has also been established. The purpose of this study was to examine the association between socioeconomic and demographic factors and under-5 mortality in KwaZulu-Natal, South Africa. DESIGN: The study was cross-sectional, and utilises 2011 Census secondary data set from Statistics SA. Overall, the census revealed that 55 476 children under the age of 5 had died in the 12 months prior to the census nationally. In KwaZulu-Natal this figure was 15 356. The 10% sample showed that 1 474 under-5 children had died in the same period in KwaZulu-Natal. STATA 12.0 was used for the analysis. Binary logistic regression model was used to examine the association between under-5 mortality and the independent variables. RESULTS: The major findings of the study indicated that (i) male children were 1.22 times more likely to die compared to female children under the age of 5 years; (ii) mothers who had no schooling (AOR=1.82); mothers with primary level of education (AOR=2.43); and mothers with secondary level of education (AOR=1.77), were more likely to experience under-5 mortality compared to mothers with tertiary level education; (iii) mothers whose age at first birth was between 15-19 years (AOR=1.47) and those whose age at first birth was between 25-34 years (AOR=2.14) were more likely to experience under-5 mortality compared to mothers whose age at first birth was between 35-49 years; (iv) Black mothers were more likely to experience under-5 mortality compared to Indian mothers (AOR=5.99); (v) mothers who were employed were 1.22 times more likely to experience under-5 mortality compared to unemployed mothers. Lastly, under-5 mortality was less likely amongst mothers in the medium households compared to those from low income households (AOR=0.65). CONCLUSION: This study found that socioeconomic and demographic factors substantively determine under-5 mortality in KwaZulu-Natal. Evidence from this study suggest that interventions aimed at reducing under-5 mortality should focus on black women, the younger women, the less educated and those with low household income.

This study analyses the 1996 South African population census from a feminist perspective by focusing on the questions pertaining to the household. It considers the issue of gender power relations operating at the level of the household and challenges the underlying patriarchal ideology embedded in the census itself. The study into households is situated within the context of current development discourse and practice, and is premised on the role of the census as a key national resource providing information on all sectors of society. Individual structured interviews were carried out with members of the census task team who provided valuable insight into the process of census making. Interviews with academics and activists working on gender issues were also conducted. A semi-structured focus group discussion was conducted with five women living in the Molweni district in KwaZulu-Natal in August 1998 to gather information on productive, reproductive and community managing work and activities. The study makes an argument about the importance of including unpaid reproductive work in our national statistics. The census questionnaire is analysed and a few adjustments are recommended that may allow for the inclusion of unpaid, reproductive labour in the national statistical system.

Measuring socioeconomic position (SEP) in population chronic disease and risk factor surveillance systems is essential for monitoring changes in socioeconomic inequities in health over time. A life course approach in epidemiology considers the long-term effects of physical and social exposures during gestation, childhood, adolescence, and later adult life on health. Previous studies provide evidence that socioeconomic factors at different stages of the life course influence current health status. Measures of SEP during early life to supplement existing indicators of current SEP are required to more adequately explain the contribution of socioeconomic factors to health status and monitor health inequities. The aim of this thesis was to examine how a life course perspective could enhance the monitoring of SEP in chronic disease and risk factor surveillance systems. The thesis reviewed indicators of early life SEP used in previous research, determined indicators of early life SEP that may be useful in South Australian surveillance systems, and examined the association of SEP over the life course and self-rated health in adulthood across different population groups to demonstrate that inclusion of indicators of early life SEP in surveillance systems could allow health inequities to be monitored among socially mobile and stable groups. A variety of indicators, such as parents’ education level and occupation, and financial circumstances and living conditions during childhood, have been used in different study designs in many countries. Indicators of early life SEP used to monitor trends in the health and SEP of populations over time, and to analyse long-term effects of policies on the changing health of populations, need to be feasible to measure retrospectively, and relevant to the historical, geographical and sociocultural context in which the surveillance system is operating. Retrospective recall of various indicators of early life SEP was examined in a telephone survey of a representative South Australian sample of adults. The highest proportions of missing data were observed for maternal grandfather’s occupation, and mother’s and father’s highest education level. Family structure, housing tenure, and family financial situation when the respondent was aged ten, and mother and father’s main occupation had lower item non-response. Respondents with missing data on early life SEP indicators were disadvantaged in terms of current SEP compared to those who provided this information. The differential response to early life SEP questions according to current circumstances has implications for chronic disease surveillance examining the life course impact of socioeconomic disadvantage. While face-to-face surveys are considered the gold standard of interviewing techniques, computer-assisted telephone interviewing is often preferred for cost and convenience. Recall of father’s and mother’s highest education level in the telephone survey was compared to that obtained in a face-to-face interview survey. The proportion of respondents who provided information about their father’s and mother’s highest education level was significantly higher in the face-to-face interview than in the telephone interview. Survey mode, however, did not influence the finding that respondents with missing data for parents’ education were more likely to be socioeconomically disadvantaged. Alternative indicators of early life SEP, such as material and financial circumstances, are likely to be more appropriate than parents’ education for life course analyses of health inequities using surveillance data. Questions about family financial situation and housing tenure during childhood and adulthood asked in the cross-sectional telephone survey were used to examine the association of SEP over the life course with self-rated health in adulthood. Disadvantaged SEP during both childhood and adulthood and upward social mobility in financial situation were associated with a reduced prevalence of excellent or very good health, although this relationship varied across gender, rurality, and country of birth groups. Trend data from a chronic disease and risk factor surveillance system indicated that socioeconomic disadvantage in adulthood was associated with poorer self-rated health. The surveillance system, however, does not currently contain any measures of early life SEP. Overlaying the social mobility variables on the surveillance data indicated how inequities in health could be differentiated in greater detail if early life SEP was measured in addition to current SEP. Inclusion of life course SEP measures in surveillance will enable monitoring of health inequities trends among socially mobile and stable groups. Life course measures are an innovative way to supplement other SEP indicators in surveillance systems. Considerable information can be gained with the addition of a few questions. This will provide further insight into the determinants of health and illness and enable improved monitoring of the effects of policies and interventions on health inequities and intergenerational disadvantage.

Mother’s nutrition knowledge, one of the guiding factors in developing children’s healthy eating patterns, has received relatively little research attention. This study determines the influence of demographic factors on mothers’ nutritional knowledge in Mthatha in the Eastern Cape Province of South Africa. Quantitative, exploratory descriptive survey used group administrative questionnaire. Closed and open ended questions solicited data in 350 purposely and conveniently selected respondents. SSPS 26.0 Version analysed the data and Factor Analysis summarized for easy interpretation. Although SA FBDG are based on the current consumption of locally available foods, respondents were largely unaware of this tool. Mothers receive informal education on Dietary Guidelines from health centres, but no one knows the extent to which they understand and apply the information. There is general lack of correlation between nutrition knowledge and its application. Mothers require nutrition education and practical application of FBDG to improve their and children’s nutrition security.
