Dietary patterns throughout adult life are associated with body mass index, waist circumference, blood pressure, and red cell folate

Dietary patterns are important in the prevention of chronic disease; however, there are few studies that include repeat measures of dietary patterns. The objective of this study was to assess the relations between dietary patterns during adult life (at ages 36, 43, and 53 y) and risk factors for chronic disease at age 53 y. Participants of a longitudinal study of health completed a 5-d food diary at 3 occasions during adult life (n = 1265). Factor analysis was used to identify dietary patterns and a pattern score was calculated from the consumption of the food items in each dietary pattern. Means and 95% CI for dietary pattern scores were calculated for each risk factor category using random effects models adjusted for socio-demographic and health-related behaviors. In women, the fruit, vegetables, and dairy pattern was inversely associated with BMI (P < 0.004), waist circumference (P = 0.0007), blood pressure (P = 0.02), and was positively associated with red cell folate (P < 0.03). The ethnic foods and alcohol pattern was also inversely associated with blood pressure (P = 0.008), whereas the meat, potatoes and sweet foods pattern was positively associated with glycated hemoglobin (P = 0.01). In men, a mixed pattern was inversely associated with waist circumference (P = 0.02) and blood pressure (P = 0.01), whereas there were no significant associations with the ethnic foods and alcohol pattern. Specific dietary patterns throughout adult life were associated with chronic disease risk factors.

Associations between the home food environment and obesity-promoting eating behaviors in adolescence

Objective: This study examines relationships between multiple aspects of the home food environment and obesity-promoting characteristics of 12- to 13-year-old adolescents' diets, specifically frequency of consumption of high-energy fluids, sweet snacks, savory snacks, and take-out foods.

Research Methods: This was a cross-sectional study including 347 adolescents 12 to 13 years of age and their parents. Data were collected via self-completed surveys. The adolescents' diets were assessed using a Food Frequency Questionnaire derived from existing age-appropriate National Nutrition Survey data. An extensive range of domains within the home food environment were assessed. Bivariate linear regression analyses were run split by gender. Forced entry multiple linear regression analyses (adjusting for all variables significant in bivariate analyses as well as for maternal education) were also performed, stratified by the sex of the child.

Results: The influence of mothers, either as models for eating behaviors or as the providers of food, was pervasive. Mothers' intake of high-energy fluids (p = 0.003), sweet snacks (p = 0.010), savory snacks (p = 0.008), and take-out food (p = 0.007) was positively associated with boys' intake of all these foods. In addition, mothers' intake of high-energy fluids was positively associated with daughters' consumption of these drinks (p = 0.025). Furthermore, availability of unhealthy foods at home was positively associated with girls' sweet snack (p = 0.001), girls' savory snack (p < 0.001), boys' savory snack (p = 0.002), and, in the bivariate analyses, girls' high-energy fluid consumption (p = 0.002).

Discussion: This study of home food environment influences on adolescent diet highlights the pervasive influence of mothers in determining adolescents' obesity-promoting eating, providing direction for obesity prevention strategies and future research.

Fresh kids: the efficacy of a health promoting schools approach to increasing consumption of fruit and water in Australia

The Fresh Kids programme utilized the Health Promoting Schools (HPSs) framework to design a whole-of-school, multifaceted intervention targeting specific behaviours to promote healthy eating and reduce the risk factors associated with childhood obesity. The aim of the programme was to evaluate the effectiveness of the HPS framework to increase fruit and water consumption among primary school-aged children over a 2-year period. The study design was an interrupted time series. Four primary schools in the inner west of Melbourne, Australia, participated in the programme intervention. Baseline data were collected using a lunch box audit to assess the frequency of children with fresh fruit, water and sweet drinks, either brought from home or selected from canteen lunch orders. The lunch box audit was repeated periodically for up to 2 years following programme implementation to assess the sustainability of dietary changes. Across all participating schools, significant increases between 25 and 50% were observed in the proportion of children bringing fresh fruit. Similarly, all schools recorded increases between 15 and 60% in the proportion of students bringing filled water bottles to school and reductions between 8 and 38% in the proportion of children bringing sweet drinks. These significant changes in dietary patterns were sustained for up to 2 years following programme implementation. Targeting key nutrition behaviours and using the HPS framework is an effective and simple approach which could be readily implemented in similar childhood settings. Effective strategies include facilitating organizational change within the school; integrating curriculum activities; formalizing school policy and establishing project partnerships with local community nutrition and dietetic services.

Effect of carbohydrate ingestion on glucose kinetics during exercise in the heat

Six endurance-trained men [peak oxygen uptake (VO₂) = 4.58 ± 0.50 (SE) l/min] completed 60 min of exercise at a workload requiring 68 ± 2% peak VO₂ in an environmental chamber maintained at 35°C (<50% relative humidity) on two occasions, separated by at least 1 wk. Subjects ingested either a 6% glucose solution containing 1 µCi [3-³H]glucose/g glucose (CHO trial) or a sweet placebo (Con trial) during the trials. Rates of hepatic glucose production [HGP = glucose rate of appearance (R_a) in Con trial] and glucose disappearance (R_d), were measured using a primed, continuous infusion of [6,6-^₂H]glucose, corrected for gut-derived glucose (gut R_a) in the CHO trial. No differences in heart rate, VO₂, respiratory exchange ratio, or rectal temperature were observed between trials. Plasma glucose concentrations were similar at rest but increased (P < 0.05) to a greater extent in the CHO trial compared with the Con trial. This was due to the absorption of ingested glucose in the CHO trial, because gut R_a after 30 and 50 min (16 ± 5 µmol · kg^-1 · min^-1) was higher (P < 0.05) compared with rest, whereas HGP during exercise was not different between trials. Glucose R_d was higher (P < 0.05) in the CHO trial after 30 and 50 min (48.0 ± 6.3 vs 34.6 ± 3.8 µmol · kg^-1 · min^-1, CHO vs. Con, respectively). These results indicate that ingestion of carbohydrate, at a rate of ~1.0 g/min, increases glucose Rd but does not blunt the rise in HGP during exercise in the heat.

The German corporate governance model in the wake of company law harmonisation in the European Union

In this article the authors deal with several recent developments in the European Union (EU) regarding company law harmonisation. These developments took place at the same time that the German corporate governance model has been refined considerably. The authors conclude that these developments in the EU and Germany respectively will necessarily create tension within the EU as far as corporate governance and company law harmonisation are concerned.

Guest editorial

An examination of Australian media reports over the last twelve months on the subject of Indigenous arts suggests a number of significant contradictions. Indigenous affairs Minister Amanda Vanstone called Aboriginal arts ‘Australia’s greatest cultural gift to the world’ (Australian, 24 January 2006), while the always-controversial expatriate Germaine Greer argued that much Indigenous art was in fact poor quality and ‘a big con’ (West Australian, 13 December 2005). Curators at France’s Musee du Quai Branly dedicated a wing of the new gallery to Aboriginal art. Yet many Indigenous leaders – including David Ross from the Central Land Council and Hetti Perkins, curator of Indigenous Arts at the Art Gallery of NSW – continue to publicise the widespread exploitation of Aboriginal artists in Central Australia by unscrupulous art dealers (Northern Territory News, 22 December 2005). Former head of the Northern Land Council and former Australian of the Year, Galarrwuy Yunupingu, who twenty years ago presented Bob Hawke with the painting Barunga Statement in celebration of the government’s commitment to a treaty, recently threatened to take the painting back from Parliament House in protest against ‘successive governments’’ neglect of Indigenous policy (Sydney Morning Herald, 21 January 2006). And in the performing arts, Richard Walley drew attention to the lack of professional recognition of Indigenous performing artists (Australian, 24 January 2006).

Such contradictions within the management and marketing of Indigenous arts have persisted for several years, and it was in response that this special issue of the Asia Pacific Journal of Arts and Cultural Management was initiated. As guest editors, we sought to present research that examines, more deeply and constructively, the marketing of Indigenous arts in Australia both historically and in the present. What emerges from this collection of five papers is a familiar scholarly theme: a tension between the ‘periphery’ and the ‘centre’, between outback and city, between larger and smaller Australian states and between Australia and other nations.

Jonathan Sweet’s ‘UNESCO and cultural heritage practice in Australia in the 1950s’ looks at the evolving relationship between Australia and the United Nations through an analysis of a significant touring exhibition: Australian Aboriginal Culture. Sweet pinpoints the 1950s as a period in which Australian museology’s approach to Indigenous cultures gradually changed, and in which Australian participation in UNESCO through the exhibition helped shape the ideological position UNESCO advocated. His article provides a useful historical contrast against which the following four articles may be read.

Chapman, Cardamone, Manahan and Rentschler look at local and contemporary issues in Indigenous arts marketing. Katrina Chapman’s ‘Positioning urban Aboriginal art in the Australian Indigenous art market’ investigates perceptions about contemporary urban Aboriginal art, concluding that the estrangement – and indeed stereotyping – of urban and traditional art creates a false set of values that urban artists are challenging. Similarly, Megan Cardamone, Esmai Manahan and Ruth Rentschler contrast perceptions of Aboriginal arts from the northern and south-eastern states, identifying crucial misconceptions that contribute to the value system applied to these arts. As Ruth Rentschler is a joint editor of this issue, the review process for this article has been managed by Katya Johanson as co-editor.

Two case studies of marketing the arts – which look at different artforms and in opposite sides of the country – then follow. Jennifer Radbourne, Janet Campbell and Vera Ding’s ‘Building audiences for Indigenous theatre’ analyses research on audiences and potential audiences for Kooemba Jdarra – Brisbane’s Indigenous performing arts company – to identify the ways in which audience attendance may be encouraged.

Finally, Jacqui Healy’s ‘Balgo 4-04’ provides a close examination of a unique art exhibition: a major commercial exhibition of the kind usually seen in Sydney and Melbourne, held in an arts centre in the middle of the Tanami Desert and retailing directly to collectors.
