Socio-economic variables influence the prevalence of inadequate nutrient intake in Brazilian adolescents: results from a population-based survey

Objective: To estimate the prevalence of inadequate nutrient intake among adolescents and the association between socio-economic variables and nutritional status. Design: Cross-sectional study with a population-based sample. Settings: The usual nutrient intake distribution was estimated using the Iowa State University method. The Estimated Average Requirement cut-off point method was used to determine the proportion of adolescents with inadequate intake for each nutrient, according to sex, income, parental educational level and nutritional status. Subjects: Twenty-four-hour dietary recalls were applied in 525 male and female Brazilian adolescents aged 14-18 years. Results: The highest prevalence of inadequate nutrient intake was observed for vitamin E (99% in both sexes). For male and female adolescents, the prevalence of inadequate intake was: Mg, 89% and 84%; vitamin A, 78% and 71 %; vitamin C, 79% and 53%; and vitamin B(6), 21% and 33%, respectively. The prevalence of inadequate intake for niacin, thiamin, riboflavin, Se, Cu and vitamin B(12) was <15 %. Individuals in the lower income and lower parental educational level strata had the highest risk of having inadequate intake for P, riboflavin and vitamins A, B(6) and B(12). Compared with non-overweight individuals, overweight individuals had a higher risk of inadequate intake for Mg, vitamin A, P, thiamin and riboflavin. Conclusions: The present study found a high prevalence of inadequate intake of nutrients that are recognised as being protective against chronic diseases. Adolescents in the lower income and lower parental educational level strata were less likely to have their nutrient intake requirements met.

Mental health promotion and socio-economic disadvantage: lessons from substance abuse, violence and crime prevention and child health

Issue addressed: Mental health promotion aimed at populations with low socio-economic status (SES) may benefit by investigating prevention strategies that effectively address related child and adolescent problems.
Methods: Evidence from a number of literature reviews and program evaluations was synthesised. First, the impact of SES on development from childhood to adulthood is considered in light of research on substance
abuse, violence, crime, and child development problems. Second, evaluations of interventions are reviewed to identify those that have shown outcomes in research studies (efficacy) or in real-world settings (effectiveness) in reducing developmental problems associated with low SES. Low SES is measured in different ways including low levels of education and/or income or definitions that combine several variables into a new indicator of low SES.
Results: Factors associated with low SES are also associated to varying extent with the development of violence and crime, substance abuse and child health problems. Interventions that address underlying determinants of low SES show strong efficacy in decreasing adolescent crime and violence and effectiveness in improving child health outcomes. Although there is limited efficacy evidence that substance abuse prevention can be effectively addressed by targeting low SES, programs designed to improve educational pathways show some efficacy in reducing aspects of adolescent substance use.
Conclusion: Mental health promotion strategies can draw on the approaches outlined here that are associated with the prevention of child and adolescent problems within low SES communities. Alternatively, such interventions could be supported in mental health promotion policy as they may assist in preventing related problems that undermine mental health.

Tracking the nomadic life of the educational researcher :- what future for feminist public intellectual(s) and/in the performative postmodern university

Is the idea of the liberal university dead, has the post modern university any chance of being emancipatory, has the theory practice divide merely collapsed in an era of 'new knowledge work', or has the university just become one aspect of market state and global capitalism. Knowledge based economies simultaneously locate universities as central to the commodification and management of knowledge while the legitimacy of the university and the academic as knowledge producers is challenged by post modernist, feminist, postcolonial and indigenous claims within a wider trend towards the 'democratisation of knowledge' and a new educational instrumentalism and opportunism. What becomes of the educational researcher, and indeed for their professional organizations, in this changing socio political and economic scenario? Is our role one of policy service or policy critique, technical expert or public intellectual? In particular what place is there for feminist public intellectuals in a socalled era of post feminism and public-/private convergence? The paper draws on recent debates around the nature of knowledge based societies, trends in relations between policy and educational research, and draws upon feminist and critical perspectives to mount a case for the importance of the postmodern university and the public intellectual.

Whose homework? researching parental labour in socio-economically diverse communities

Recent government education policies in Britain, USA and Australia advocate increased parental involvement in schooling. In the context of inadequate resourcing of public schools, increasingly parents assume significant responsibility for their children's education through active involvement in schools and at home. However, numerous studies have identified barriers to inclusion in the life of schools faced by families living in poverty, by families whose first language is not English, by Indigenous families. Class linked analyses of homework suggest that homework can be a source of stress in many families which serves to reinforce educational and social inequalities and underline cultural differences.


This paper reports on a feminist ethnographic study of homework which examines the nature and underlying purposes of tasks children bring from school for completion at home, the impact of homework on families, and the kinds of parental labour performed in homes where homework is completed. It reconceptualises homework as a 'field of practice' and develops a Bourdiueian analysis of parental management of homework across 2 socio-economically diverse communities. The paper argues that the pedagogical work in the home is increasingly complex and that the labour performed by parents is misunderstood and devalued in policies which shape homework.

How socio-economic status contributes to participation in leisure-time physical activity

The aim of this cross-sectional study was to identify individual, social, and environmental contributors (mediators) to individual- and area-level differences in leisure-time physical activity across socio-economic groups. A two-stage stratified sampling design was used to recruit 20–65 year old adults (N = 2194) living in 154 census collection districts of Adelaide, Australia (overall response rate: 12%). Participants completed two surveys six months apart (response rate on the second survey: 83%). Individual-level socio-economic status (SES) was assessed using self-report measures on educational attainment, household income, and household size. Area-level SES was assessed using census data on median household income and household size for each selected census district. Bootstrap generalized linear models were used to examine associations between SES, potential mediators, and leisure-time physical activity. The product-of-coefficient test was used to estimate mediating effects. All SES measures were independently associated with potential individual and social mediators of the SES-activity relationships. Individual- and area-level income was also associated with perceived neighborhood attributes. Self-efficacy and social support for physical activity explained virtually all of the differences in physical activity across educational attainment groups. Physical barriers to walking and access to public open space contributed in part to the explanation of differences in recreational walking across income groups. Yet, self-efficacy and social support were the key mediators of the observed relationships between individual- and area-level income and physical activity. This study suggests that in order to increase physical activity participation in the more disadvantaged segments of the population, comprehensive, multilevel interventions targeting activity-related attitudes and skills as well as social and physical environments are needed.

Serving community : prosocial engagement in educational administration

The rise of managerialism in the 1990s entrenched bureaucratic practices as core education and training for educational administrators. As the educational divide between those who achieve and those who fall short continues to problematize the success of educational reforms, the work of administrators becomes critical to review. The current challenge for educational administration is to provide an environment that genuinely serves the interests of complex diversity and social justice in education systems by building the frameworks that respects differences, protects the weak, and regulates the strong. By taking a more prosocial stance with issues relating to cultural diversity, equity, and democracy, educational administration can transform society, the school, and the classroom, through humanistic and interpretive management practices, and influencing pedagogy, curriculum, educator training, and the socio-political system.

Personal, social and environmental correlates of resilience to physical inactivity among women from socio-economically disadvantaged backgrounds

While sex and socio-economic disparities in physical activity have been well documented, not all disadvantaged women are inactive. This study aimed to examine correlates of achieving recommended levels of physical activity among women of low socio-economic position. In 2005, a population-based sample of 291 women with low educational attainment provided survey data on leisure time physical activity (LTPA). Participants reported potential personal (enjoyment and self-efficacy; barriers; intentions; guilt and priorities; routines and scheduling; occupational physical activity; television viewing), social (support from family/friends; social participation; sport/recreation club membership; dog ownership) and environmental (aesthetics; safety; local access; footpaths; interesting walks; busy roads to cross; heavy traffic) correlates of physical activity. Nearly 40% of participants achieved recommended LTPA (150 min week–1). Multivariable analyses revealed that higher levels of self-efficacy for walking [prevalence ratio (PR) 2.05, 95% confidence interval (CI) 1.19–3.53], higher enjoyment of walking (PR 1.48, 95% CI 1.04–2.12), greater intentions to be active (PR 1.97, 95% CI 1.12–3.45) and having set routines for physical activity (PR 1.91, 95% CI 1.18–3.09) were significantly associated with achieving recommended LTPA. Personal factors were the characteristics most strongly associated with achieving recommended levels of LTPA among women from socio-economically disadvantaged backgrounds.

Socio-economic and demographic variations in school lunch participation of French children aged 3-17 years

Objective: To assess school canteen attendance in a French nationally representative sample of children and to analyse its association with the socioeconomic and demographic characteristics of the children and their families.
Design: Data from the second French national cross-sectional food consumption survey (INCA2), performed in 2006–2007, were used. Information on usual weekly school canteen attendance was collected through a self-reported questionnaire, and demographic and socio-economic variables through a face-to-face questionnaire. The associations between school canteen attendance and the socio-economic and demographic variables were investigated by multivariate logistic regression analyses.
Setting: The INCA2 sample was representative of the children aged 3–17 years in France.
Subject: Analysis was performed on 1413 schoolchildren who completed the school canteen attendance questions.
Results: Some 65?6% of schoolchildren aged 3–17 years had school lunch at least once weekly. This rate of attendance was positively correlated with age. Whatever the school level, school canteen attendance was positively associated with the educational level of the caregiver/parent. In pre- and elementary-school children, enrolment at the school canteen was also higher when the caregiver/parent worked, or in single-parent families. In secondary-school children, school lunch participation decreased with children living in more densely populated areas and increased with the level of the household’s living standards.
Conclusions: School canteen attendance was positively associated with children’s socio-economic background. This could reduce the effectiveness of the forthcoming school meal composition regulations designed to improve the diet of children from deprived backgrounds, who are more likely to have unhealthy food habits.

'I'm your new teacher' : the impact of teacher mobility on educational opportunities for marginalised students

This article provides an alternative perspective on what it means to 'do school' in a disadvantaged community, particularly in the way that disadvantage is reproduced for marginalised students. It explores the mobility of teachers (temporarily) working in a small secondary school located in an economically depressed regional community in Australia, characterised by high levels of unemployment, high welfare dependency and a significant indigenous population. Like many disadvantaged schools, the school has difficulty attracting and retaining high ability teachers, instead relying on a high turnover of often-reluctant staff who are sent to (or feel compelled to) fill positions unable to be resourced through teacher choice procedures. Drawing on parent, student, and teacher interviews, we ask: how does teacher mobility in this context influence the educational opportunities of students who are 'on the margins' of school success and of the socio-economic structure? Specifically, we explore the ways that teacher mobility can reproduce disadvantage by limiting students' access to the dominant cultural capital. We argue that educational policies and politics that reward teacher mobility for moving out of these communities, work to disadvantage students. What is needed is a transformation in policies governing staff placements to establish alternatives that redefine the reward system for teachers in ways that permit these students to succeed.

Socio-scientific issues in education : innovative practices and contending epistemologies

In the past decade, we have seen the well-established discourse of environmental education (EE) supplanted by that of education for sustainability (EfS). In some ways this change in terminology has been no more than a slogan change, with the actual educational practices associated with EfS little changed from those qualified by EE (Campbell and Robottom 2008). Environment-related education activities under both terms frequently focus on socio-scientific issues – which serve as the chief organising principle for a range of related curriculum activities – and are shaped by the particular characteristics of these issues. Socio-scientific issues are essentially constituted of questions that are philosophical as well as empirical in nature. Socio-scientific issues consist in contests among dissenting social, economic and environmental perspectives that rarely all align, giving rise to debates whose resolution is not amenable to solely scientific approaches. Socio-scientific issues, then, exist at the intersection of differing human interests, values and motivations and are therefore necessarily socially-constructed. An adequate educational exploration of these issues requires a recognition of their constructedness within particular communities of interest and of the limitation of purely applied science perspectives, and, in turn, requires the adoption of curricular and pedagogical approaches that are in fundamental ways informed by constructivist educational assumptions – at least to the extent that community constructions of socio-scientific issues are recognised as being shaped by human interests and social and environmental context. This article considers these matters within the context of examples of environment-related practice drawn from two geographical regions. The article will argue that a serious scientific element is both necessary and insufficient for a rigorous educational exploration of socio-scientific issues within either the EE or EfS discourses, and will consider some implications for professional development and research in this field.

Correlates of socio-economic inequalities in women’s television viewing : a study of intrapersonal, social and environmental mediators

Introduction

Socio-economically disadvantaged women are at a greater risk of spending excess time engaged in television viewing, a behavior linked to several adverse health outcomes. However, the factors which explain socio-economic differences in television viewing are unknown. This study aimed to investigate the contribution of intrapersonal, social and environmental factors to mediating socio-economic (educational) inequalities in women's television viewing.
Methods

Cross-sectional data were provided by 1,554 women (aged 18-65) who participated in the 'Socio-economic Status and Activity in Women study' of 2004. Based on an ecological framework, women self-reported their socio-economic position (highest education level), television viewing, as well as a number of potential intrapersonal (enjoyment of television viewing, preference for leisure-time sedentary behavior, depression, stress, weight status), social (social participation, interpersonal trust, social cohesion, social support for physical activity from friends and from family) and physical activity environmental factors (safety, aesthetics, distance to places of interest, and distance to physical activity facilities).
Results

Multiple mediating analyses showed that two intrapersonal factors (enjoyment of television viewing and weight status) and two social factors (social cohesion and social support from friends for physical activity) partly explained the educational inequalities in women's television viewing. No physical activity environmental factors mediated educational variations in television viewing.
Conclusions

Acknowledging the cross-sectional nature of this study, these findings suggest that health promotion interventions aimed at reducing educational inequalities in television viewing should focus on intrapersonal and social strategies, particularly providing enjoyable alternatives to television viewing, weight-loss/management information, increasing social cohesion in the neighborhood and promoting friend support for activity.

Introduction : In Australian educational researcher, v.39 v.4

This special issue can be situated in the ‘affective turn’ in education. It responds to the increasing significance of affect, emotions and creativity as the foci of contemporary educational research. The resurgence of interest in these issues is symptomatic of current educational reforms and their impact on how educators should think about, and practise, teaching andwhat students need to know and howthey should learn. It is not to say that the current reforms are radically dissimilar from the previous ones in terms of their general intention to bring about change.What is different, though, is theweight they put on standards, accountability, efficiency, performativity and valueaddedness. As a result, the economic, market-driven principles of reforms have subsumed all other dimensions of education, such as its socio-cultural and relational aspects. The turn to affect is driven by a recognition that the economic rationalisation of education is at odds with its emotional and creative dimensions. The turn is registering a change in how education is managed and, indeed, what counts as education today.

Educational inequalities in women's depressive symptoms : the mediating role of perceived neighbourhood characteristics

Socio-economically disadvantaged (e.g., less educated) women are at a greater risk of depression compared to less disadvantaged women. However, little is known regarding the factors that may explain socioeconomic inequalities in risk of depression. This study aimed to investigate the contribution of perceived neighbourhood factors in mediating the relationship between education and women’s risk of depression. Cross-sectional data were provided by 4,065 women (aged 18–45). Women self-reported their education level, depressive symptoms (CES-D 10), as well as four neighbourhood factors (i.e., interpersonal trust, social cohesion, neighbourhood safety, and aesthetics). Single and multiple mediating analyses were conducted. Clustering by neighbourhood of residence was adjusted by using a robust estimator of variance. Multiple mediating analyses revealed that interpersonal trust was the only neighbourhood characteristic found to partly explain the educational inequalities in women’s depressive symptoms. Social cohesion, neighbourhood aesthetics and safety were not found to mediate this relationship. Acknowledging the cross-sectional nature of this study, findings suggest that strategies to promote interpersonal trust within socioeconomically disadvantaged neighbourhoods may help to reduce the educational inequalities in risk of depression amongst women. Further longitudinal and intervention studies are needed to confirm these findings.

Socio-demographic lifestyle and psychological predictors of benzodiazepine and z-hypnotic use patterns

Aims : Risk and demographic factors for benzodiazepine and z-hypnotic use are incompletely understood. The aim of the paper was therefore to investigate socio-demographic, lifestyle and psychological factors predicting onset and differential pattern of prescribed benzodiazepine and z-hypnotic use in a Norwegian population sample.

Methods : This retrospective cohort study obtained socio-demographic, psychological and lifestyle variables from the Nord-Trøndelag Health Study. Information about benzodiazepine prescriptions from the Norwegian prescription database were linked to epidemiological questionnaire data. Benzodiazepine use was classified into single-period, intermittent and chronic use, and high dose use was defined as being prescribed a yearly average above 180 daily defined doses.

Results : Older age, sleep difficulties and smoking were positively associated with all patterns of benzodiazepine use. Male gender was related to a reduced risk of all patterns of use, whereas educational achievement was negatively associated with single-period use. Alcohol consumption, anxiety and tension were positively related to intermittent and chronic use, while exercise was negatively related to chronic use. Smoking, sleep difficulties and old age were positively associated with prescriptions of high benzodiazepine doses, while exercise was associated with lower doses.

Conclusions : Patterns of prescribed benzodiazepine use are linked to demographic, lifestyle and clinical variables. Non-pharmacological treatment for sleep difficulties and smoking cessation may reduce the risk of chronic benzodiazepine use.

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.
