Sources of stress in impoverished neighbourhoods : insights into links between neighbourhood environments and health

Objective : We consider associations between individual, household and area-level characteristics and self-reported health.
Method : Data is taken from baseline surveys undertaken in 13 socio-economically disadvantaged neighbourhoods in Victoria (n=3,944). The neighbourhoods are sites undergoing Neighbourhood Renewal (NR), a State government initiative redressing place-based disadvantage.
Analysis :This focused on the relationship between area and compositional factors and self-reported health. Area was coded into three categories; LGA, NR residents living in public housing (NRPU) and NR residents who lived in private housing (NRPR). Compositional factors included age, gender, marital status, identifying as a person with a disability, level of education, unemployment and receipt of pensions/benefits.
Results : There was a gradient in socio-economic disadvantage on all measures. People living in NR public housing were more disadvantaged than people living in NR private housing who, in turn, were more disadvantaged than people in the same LGA. NR public housing residents reported the worst health status and LGA residents reported the best.
Conclusions : Associations between compositional characteristics of disability, educational achievement and unemployment income and poorer self-reported health were shown. They suggested that area characteristics, with housing policies, may be contributing to differences in self-reported health at the neighbourhood level.
Implications : The clustering of socio-economic disadvantage and health outcomes requires the integration of health and social support interventions that address the circumstances of people and places.

Getting the complete picture : combining parental and child data to identify the barriers to social inclusion for children living in low socio-economic areas

Background: Childhood mental health problems are prevalent in Australian children (14–20%). Social exclusion is a risk factor for mental health problems, whereas being socially included can have protective effects. This study aims to identify the barriers to social inclusion for children aged 9–12 years living in low socio-economic status (SES) areas, using both child-report and parent-report interviews.

Methods: Australian-born English-speaking parents and children aged 9–12 years were sampled from a low SES area to participate in semi-structured interviews. Parents and children were asked questions around three prominent themes of social exclusion; exclusion from school, social activities and social networks.

Results: Many children experienced social exclusion at school, from social activities or within social networks. Overall, nine key barriers to social inclusion were identified through parent and child interviews, such as inability to attend school camps and participate in school activities, bullying and being left out, time and transport constraints, financial constraints and safety and traffic concerns. Parents and children often identified different barriers.

Discussion: There are several barriers to social inclusion for children living in low SES communities, many of which can be used to facilitate mental health promotion programmes. Given that parents and children may report different barriers, it is important to seek both perspectives.

Conclusion: This study strengthens the evidence base for the investments and action required to bring about the conditions for social inclusion for children living in low SES communities.

Crisis in Clio's family : a study of the discipline of Australian economic history 1918-1965

This thesis presents an intellectual history of the historiography of Australian Economic History between 1918 and 1965. More specifically, it is a contribution to a relatively novel area of research into 'disciplinary history’. It takes as its basic analytical material the four books widely used for significant lengths of time for undergraduate teaching during the period of the study. The thesis consists of five main chapters, plus an appendix which surveys the institutional development of Australian Economic History and provides the empirical basis for the selection of the works named above. After a brief introduction and overview, the next four chapters consist of a detailed study of one of these works, the historical context in which each was written, and an intellectual biography. The fifth chapter is largely theoretical and conceptual. It analyses the epistemological bases of History and Economics and explores the implications of different models of knowledge for the relationship between Economic History and its two antecedent disciplines, History and Economics. Current perceptions of the state of the discipline in Australia and overseas are also examined. There are three main propositions advanced and their implications explored in the fifth chapter. First, that changes which occurred in Australian Economic History during the period 1918-1965 shifted the discipline from the broad area of History to the broad area of Economics. Second, that the inherent tension and fundamental differences between the two disciplinary areas of History and Economics have profound and complex implications for Australian Economic History at a number of levels and in a number of areas. The third proposition posits that the paradigm shift of the 1950s/1960s in Australian Economic History, and the paradigm shift of the 1960s/1970s in Economic History respectively have resulted in crisis. The final part of the chapter summarises the contents of the preceding chapters, and draws some conclusions based on those detailed studies.

An index of unhealthy lifestyle is associated with coronary heart disease mortality rates for small areas in England after adjustment for deprivation

Indices of socio-economic deprivation are often used as a proxy for differences in the health behaviours of populations within small areas, but these indices are a measure of the economic environment rather than the health environment. Sets of synthetic estimates of the ward-level prevalence of low fruit and vegetable consumption, obesity, raised blood pressure, raised cholesterol and smoking were combined to develop an index of unhealthy lifestyle. Multi-level regression models showed that this index described about 50% of the large-scale geographic variation in CHD mortality rates in England, and substantially adds to the ability of an index of deprivation to explain geographic variations in CHD mortality rates.

Is economic development in the Pacific island countries export led or import led?

This article examines the export-led growth and import-led growth hypotheses for a panel of Pacific island countries—namely, Fiji, Papua New Guinea, Solomon Islands, Tonga and Vanuatu—for the period 1982–2004. The modelling is performed using a panel unit root, panel co-integration and panel Granger causality approach. We find bi-directional Granger causality for the panel of Pacific island countries between exports and economic growth, imports and economic growth, and exports and imports. The results suggest that the poor growth performance of many Pacific island countries reflects their poor export performance; however, if the supply-side constraints on exports are removed, there could be a virtuous cycle between economic growth and exports.

Scores on the dietary guideline index for children and adolescents are associated with nutrient intake and socio-economic position but not adiposity 1-3

Diet quality indices reflect overall dietary patterns better than single nutrients or food groups. The study aims were to develop a measure of adherence with dietary guidelines applicable to child and adolescent populations in Australia and determine the association between index scores and food and nutrient intake, socio-demographic characteristics, and measures of adiposity. Data were analyzed from 4- to 16-y-old participants of the 2007 Australian Children’s Nutrition and Physical Activity Survey (n = 3416). The Dietary Guideline Index for Children and Adolescents (DGI-CA) comprises 11 components: 5 core food groups, wholegrain bread, reduced-fat dairy foods, extra foods (nutrient poor and high in fat, salt, and added sugar), healthy fats/oils, water, and diet variety (possible score of 100). The index criteria were age specific. The mean DGI-CA score was low (53.6 ± 0.4), similar between boys and girls, and differed by age; the youngest children scored higher than the oldest children (P < 0.0001). Higher DGI-CA scores were associated with lower energy intake, energy density, total and saturated fat, and sugar intake; higher protein, carbohydrate, fiber, calcium, iron, vitamin C, vitamin A, folate, phosphorous, magnesium, zinc, and iodine intakes; and a higher polyunsaturated:saturated fat ratio (P < 0.0001). DGI-CA scores were associated with socio-economic characteristics and measures of family circumstance. Weak positive associations were observed between DGI-CA score and BMI or waist circumference Z-scores in the 4- to 10-y and 12- to 16-y age groups only. This index is the first validated index in Australia and one of the few international indices to describe the diet quality of children and adolescents.

Pakistan’s twin interrelated challenges : economic development and security

The 2010 devastating floods in Pakistan have starkly reminded the world of the two critical, interrelated challenges confronting Pakistan: economic development and security. And whilst the Pakistan government's capacity to deal with these two issues before the flood was already shaky at best, its position now is even more precarious given the enormity of the task of rebuilding the infrastructure that has been destroyed in this latest natural disaster. Nuclear-armed Pakistan is a large and strategically important country, critically located on one of the world's most important geopolitical crossroads. It is a pivotal player in a region—covering the Middle East, Central Asia and South Asia—which has much potential, but which also has unresolved conflicts and various degrees of instability. Accordingly, because Pakistan is so important to the stability of the region and the world at large, it is vital that it be able to address successfully these twin challenges.

Increasing the level of sustainability via off-site production : a study of the residential construction sector in China

Even though the use of off-site production in the construction process for residential buildings is seen as a viable means of increasing the level of sustainability with respects to its significant economic, environmental and social contributions, there have been very few studies to-date into off-site construction within the context of developing countries where the places have crucial demands for accommodations. Accordingly this research involves the rapidly growing developing nation, China, as a representative developing country with the objective to investigate the current status of off-site practices in the urban residential construction sector. This paper also examines the factors affecting demand for and potential barriers against a wider uptake of off-site technologies in China. The findings provide a rare insight into off-site construction in China’s housing industry and this information will be transferable to other developing countries. This study also contributes to a broader understanding about the off-site construction in developing from an international perspective.

Sitting time and socio-economic differences in overweight and obesity

Objectives: To examine (1) the inter-relationships between socio-economic status (SES), physical activity, three different domains of sitting time (weekday, weekend day and leisure-time sitting), and being overweight or obese (body mass index25 kg/m2); and (2) the potential mediation effects of sitting time in the relationship between socio-economic factors and being overweight or obese in working Australian adults.

Design: Observational epidemiological study.

Subjects: One thousand forty eight working adults. Using a multistage sampling design on neighbourhood SES, participants were from high and low SES neighbourhoods of an Australian capital city.

Measurements: Neighbourhood SES was assessed using census data; individual SES was based on self-reported educational attainment and household income. There were three sitting time variables: sitting time on weekdays, weekend days and in leisure time. Overweight and obesity were determined using self-reported body weight and height.

Results: Gender, age, neighbourhood SES, education, working hours and physical activity were independently associated with weekday, weekend day and leisure-related sitting time. With the exception of education and working hours, these variables were also independently associated with being overweight or obese. Leisure-time sitting was found to be a mediator in the relationships between gender, education and being overweight or obese.

Conclusion: Strategies to promote less sitting in leisure time are required to combat overweight and obesity in Australian adults, especially among those from low SES neighbourhoods, and among those with high levels of education and income who work long hours.

Type 2 diabetes prevalence varies by socio-economic status within and between migrant groups: analysis and implications for Australia

Background:
Ethnic diversity is increasing through migration in many developed countries. Evidence indicates that type 2 diabetes mellitus (T2DM) prevalence varies by ethnicity and socio- economic status (SES), and that in many settings, migrants experience a disproportionate burden of disease compared with locally-born groups. Given Australia’s multicultural demography, we sought to identify groups at high risk of T2DM in Victoria, Australia.

Socio-economic disparities in Australian adolescents' eating behaviours

Objective: To assess the association between socio-economic position (SEP) and poor eating behaviours in a large representative sample of Australian secondary school students.
Design: Cross-sectional survey of students’ vegetable, fruit, sugar-sweetened beverage and fast-food consumption assessed using validated instruments and collected via a web-based self-report format.
Setting: Secondary schools across all Australian states and territories.
Subjects: Secondary-school students (n 12 188; response rate: 54 %) aged 12–17 years participating in the 2009–10 National Secondary Students’ Diet and Activity (NaSSDA) survey.
Results: Overall, 25% of students reported consuming <1 serving of vegetables/d and 29% reported eating <1 serving of fruit/d. Fourteen per cent of students reported drinking at least 1–2 cups of sugar-sweetened beverages/d while 9% reported eating fast food <3 times/week. After adjusting for other demographic factors, students of lower-SEP areas were more likely to report low intake of vegetables (F (4, 231) = 3.61, P = 0.007) and high frequency of consumption of sugar-sweetened beverages (F (4, 231) =8.41, P < 0.001) and fast food (F (4, 231) = 4.59, P =0.001) compared with students of high-SEP neighbourhoods. A positive SEP association was found for fruit consumption among female students only (F (4, 231) = 4.20, P = 0.003). Those from lower-SEP areas were also more likely to engage in multiple poor eating behaviours (F (4, 231) = 5.80, P, < 0.001).
Conclusions: Results suggest that socio-economic disparities in Australian adolescents’ eating behaviours do exist, with students residing in lower-SEP neighbourhoods faring less well than those from high-SEP neighbourhoods. Reducing social inequalities in eating behaviours among young people should be a key consideration of future preventive strategies.

The inter-section of political history and health policy in Asia - the historical foundations for health policy analysis

One of the challenges for health reform in Asia is the diverse set of socio-economic and political structures, and the related variability in the direction and pace of health systems and policy reform. This paper aims to make comparative observations and analysis of health policy reform in the context of historical change, and considers the implications of these findings for the practice of health policy analysis. We adopt an ecological model for analysis of policy development, whereby health systems are considered as dynamic social constructs shaped by changing political and social conditions. Utilizing historical, social scientific and health literature, timelines of health and history for five countries (Cambodia, Myanmar, Mongolia, North Korea and Timor Leste) are mapped over a 30-50 year period. The case studies compare and contrast key turning points in political and health policy history, and examines the manner in which these turning points sets the scene for the acting out of longer term health policy formation, particularly with regard to the managerial domains of health policy making. Findings illustrate that the direction of health policy reform is shaped by the character of political reform, with countries in the region being at variable stages of transition from monolithic and centralized administrations, towards more complex management arrangements characterized by a diversity of health providers, constituency interest and financing sources. The pace of reform is driven by a country's institutional capability to withstand and manage transition shocks of post conflict rehabilitation and emergence of liberal economic reforms in an altered governance context. These findings demonstrate that health policy analysis needs to be informed by a deeper understanding and questioning of the historical trajectory and political stance that sets the stage for the acting out of health policy formation, in order that health systems function optimally along their own historical pathways.
