Dietary patterns of Australian adults and their association with socio-economic status: results from the 1995 national nutrition survey

Objective: To describe dietary patterns among men and women in the Australian population, and to explore how these varied according to socioeconomic status (SES).

Design: A cross-sectional self-report population survey, the 1995 Australian National Nutrition Survey (NNS), was used.

Setting: Private dwelling sample, covering urban and rural areas across Australia.

Subjects: Data provided by 6680 adults aged 18-64 who participated in the NNS were used in the analyses.

Methods: Factor analyses were used to analyse data from a Food Frequency Questionnaire (FFQ) completed by participants. Associations between SES and dietary pattens were assessed using ANOVA.

Results: Separate factor analyses of the FFQ data for men and women revealed 15 factors, accounting for approximately 50% of the variance in both men's and women's dietary patterns. Several gender and SES differences in food patterns were observed. Lower SES males more frequently consumed 'tropical fruits', 'protein foods', and 'offal and canned fish', while high SES males more often ate 'breakfast cereals' and 'wholemeal bread'. Lower SES females more often ate 'traditional vegetables', 'meat dishes' and 'pasta, rice and other mixed foods', while high SES females more frequently ate 'ethnic vegetables' and 'breakfast cereal/muesli'.

Conclusions: These findings contribute to a better understanding of the dietary patterns that underscore gender-specific SES differences in nutrient intakes. Analyses of the type employed in this study will facilitate the development of interventions aimed at modifying overall eating patterns, rather than specific components of the diet.

The DALY, context and the determinants of the severity of disease: an exploratory comparison of paraplegia in Australia and Cameroon

This paper summarises the findings of an empirical investigation of some of the technical and social assumptions on which the disability adjusted life year (DALY) is based. The objectives of the study were to examine the notion that the burden of disease is broadly similar without regard to country, environment, gender or socio-economic status and to develop detailed descriptions of the experiences of the burden of disease as they related to these contextual factors. The study was a multi-factorial exploratory study employing qualitative and quantitative techniques to obtain data on the effects of country (development), environment (urban versus rural), gender and socio-economic status on people with paraplegia. The data provided an extensive and detailed compilation of context rich descriptions of living with paraplegia. Striking features of the data were the differences between countries with respect to the impact of the health conditions on functioning and highlight a context in which paraplegia of like clinical severity can be fatal in one environment and not in another. While there has been some focus on the control of social determinants of disease, there has been little work on the social determinants of the severity of disease. The underlying assumptions of the DALY, which ignore context in the assessment of the burden of disease, risk exacerbating inequalities by undervaluing the burden of disease in less-developed countries. There is a need to continue to subject the development of indicators to rigorous debate to determine a balance between the assumption of a global “average social milieu” and the treatment of each individual as belonging to their own context in the assessment of population health in order for indicators to be meaningful cross-culturally.

Gay and Lesbian Life at Colby 1969-1974

The history of a gay and lesbian student community at Colby seems to point to the difficulty of visibility. For students who were able to find others like themselves, their group of lesbian and gay friends had to remain underground. For students who were grappling with their newly found, socially stigmatized sexuality, the experience was isolating if they did not know where to find others like themselves. This paper seeks to address the social forces that kept sexually variant students from expressing their sexual identities openly on campus. Part of this difficulty is attributable to the compulsory heterosexuality assumed by general American society at the time, manifested in the silence or outright hostility directed against homosexuals. Naturally, Colby students replicated this assumption. Some of the students we interviewed seemed to internalize compulsory heterosexuality, while it was forced upon others. Religion and psychology were two methods of enforcing heterosexuality that were relevant to the people we interviewed. Another significant obstacle to visibility was Colby's location and the nature of Colby's student body. Waterville, unlike more urban cities, did not have a history of gay life, and thus an established gay community or gay identity into which one could be socialized. Colby, as a small, homogeneous and isolated space, posed difficulties in establishing a gay community as the population to draw from was small and regulated.

Literary love making in Nicholas Sparks novels: Finding the balance between the writer’s life and the writer’s work in bestselling Romantic Literature

For almost a decade now Nicholas Sparks has been writing love stories. Not only has he been publishing his stories, but they have received high acclaim in each of their installments. Several of his novels have been made into major motion pictures and increased his popularity quite significantly. His status as a successful romantic fiction writer is undeniable, but the question is, why? What is it about Nicholas Sparks that makes his novels so engaging, and personally, what do I need to do as an aspiring novelist to try and acquire the same literary status? Sparks’s novels reach readers at a number of different levels, thus giving them appeal no matter the intellectual intent of the reader. Theoretically, Sparks engages reader response techniques as well as formalist processes such as “habitualization” and “defamiliarization,” while also developing engaging plot lines that represent many of the experiences from his own life. His writing is not only academically redeemable, but it is also creatively stimulating; between the two, Sparks represents the thunder and lightning combination all writers strive for while trying to achieve literary success. This project also offers a creative element in which I attempt to exemplify many of the traits discussed in the analytical sections of this document, by recreating them in a creative, fictitious fashion. Themes such as: motion versus stasis, life versus death, and the ordinary versus the extraordinary all exist within the narrative structure of my short story “Trip to Fall.” Besides these thematic elements, the creative section strives to represent the balance Sparks achieves between the experiences of his own life and the fictitious world he creates. Overall, this project delves into the life of Nicholas Sparks to better understand the inspiration for his writing at the level of form as well as content, while also paying tribute to Sparks’s style through a representation of his work in my own words.

VNTR polymorphism of the insulin gene and childhood overweight in a general population

Objective: The VNTR polymorphism 5' of the insulin gene has been related to obesity in a previous study on children with early onset of severe obesity. Our purpose was to analyze the association between this polymorphism and adiposity variability in an unselected population of children and adolescents in northern France.

Research Methods and Procedures: In 293 nuclear families from the Fleurbaix Laventie Ville Santé study, we genotyped the INS VNTR polymorphism in 431 children and adolescents (8 to 18 years of age) and their parents. Overweight was defined according to the international definition in both children and adults. A transmission disequilibrium test in families with an overweight offspring was performed. The prevalence of overweight was compared according to genotype. The effect of the genotype on BMI and waist circumference was tested with a linear regression model, adjusting for age, gender, and Tanner stage.

Results: There was an undertransmission of class III alleles from heterozygous parents to their overweight offspring (p < 0.002). Overweight was associated with class I alleles in children and adolescents (12% I/I, I/III vs. 3% III/III; p < 0.08). Those with a class III/III genotype had a 1 kg/m2 lower mean BMI (p = 0.04) and 3 cm lower waist circumference (p = 0.02) than those bearing one or two class I alleles. No association of adiposity or obesity with class I alleles was found in parents.

Discussion: INS VNTR polymorphism seems to contribute to differences in adiposity level in the general population of children and adolescents.

Relationship between genotype and enzyme activity of glutathione S-transferases M1 and P1 in Chinese

Glutathione S-transferases (GSTs) are the major detoxifying Phase II enzyme for eliminating electrophilic compounds. Mutations in GSTM1, GSTP1 and GSTT1 in Caucasian and GSTA1 in Chinese have been found to reduce enzyme activity. However, data on the impact of common genetic polymorphisms of GSTM1 and GSTP1 on enzyme activity in Chinese is lacking. This study aimed to investigate the effect of common GSTP1 and GSTM1 polymorphisms on erythrocyte GST activity in healthy Chinese (n = 196). GSTM1 null mutation (GSTM1*0) was analyzed by a PCR-Multiplex procedure, whereas GSTP1 313A → G polymorphism (resulting in Ile105Val at codon 105) was analyzed by PCR-restriction fragment length polymorphism (RFLP) analysis. Erythrocyte GST activity was measured using 1-chloro-2,4-dinitro-bezene (CDNB) as the model substrate. The frequency of GSTM1 null genotype was 54.3% and the frequency of GSTP1-Ile/Ile, -Ile/Val, and -Val/Val genotype was 60.7%, 35.2% and 4.1%, respectively, with a frequency of 21.7% for the 105 valine allele. Age, gender and smoking did not significantly affect the erythrocyte GST activities. The mean erythrocyte GST enzyme activity for GSTP1*-Ile/Val genotype group (3.53 ± 0.63 U/g Hb) was significantly lower than that for subjects with GSTP1-Ile/Ile genotype (4.25 ± 1.07 U/g Hb, P = 0.004), while subjects with the GSTP1-Val/Val genotype had the lowest enzyme activity (2.44 ± 0.67 U/g Hb). In addition, the GST activity in carriers of GSTM1*0/GSTP1-Ile/Ile was significantly higher than that of subjects inherited GSTM1*0/GSTP1-Ile/Val or GSTM1*0/GSTP1-Val/Val. However, there is no association between GSTM1 null mutation and reduced enzyme activity. GSTP1 codon 105 mutation led to reduced erythrocyte GST activity in Chinese. A combined GSTP1 and GSTM1 null mutations also resulted in significantly reduced GST activity. Further studies are needed to explore the clinical implications of GSTM1 and GSTP1 polymorphisms.

Youth and sexualities : pleasure, subversion and insubordination in and out of schools

These cutting-edge international essays challenge dominant narratives of queer youth predicated on oppression and victimization. As school systems address the emergence of Gay-Straight Alliances and calls to provide equal educational access, researchers, educators and youth workers are paying increasing attention to sexuality, gender and schooling. Yet present discourses are limited to liberal understandings of tolerance, safety, and equity that are defined by a separation of "queer" and "normal." This text documents and offers radical interpretations of the creativity of queer youth in challenging existing practices. Interdisciplinary analyses offer multiple vantage points for reconceptualizing adolescent sexual subjectivities and institutional and cultural practices.

Standardising differences? Theorising 'identities' and pedagogical approaches to working with diversity

‘Race’, socio-economic status, gender and ethnicity are theorised as fluid, dynamic and interconnected categories of identity within post-structural theories. Understanding identities as socio-culturally constructed offers opportunities to think differently about how teachers and teacher education students position themselves and are positioned within these discourses. In Australia, where the teaching profession is overwhelmingly Anglo-Australian (Rizvi 1992; Santoro et al, 2001), mono-lingual and of middle-class background, Australian students are becoming far more linguistically and culturally diverse. Since engagement with teachers who ‘know’ their students, (Delpit, 1995) and the communities from which they come is a major predictor of successful educational outcomes, the growing disparity between teachers’ and students’ cultural and classed experiences is of concern. While teacher education programs focus on developing the attributes in new graduates to work productively with difference, the actualities of doing so are problematic.

This paper reviews some current Australian, North American and United Kingdom approaches to working with student teachers’ constructs of self in terms of ethnicity, ‘race’ and class in order to problematise taken-for-granted ideas of ‘normal’. It considers debates that surface around ‘individuality’ versus ‘collective’ differences; additionally, some of the resistances and dilemmas that emerge when ‘white’, middle class students are asked to rethink their own positionality are examined. Questions regarding what constitutes productive ways to teach inclusive and transformative pedagogies are raised in light of current theory and practice.

Interactions between fur seals and a squid jig fishery in southern Australia

Interactions between Australian fur seals (Arctocephalus pusillus doriferus) and the Southern Squid Jig Fishery (SSJF) were investigated in April–May 2002. Details on the number of seals present, distance from the vessel, age and gender, and their behaviour were recorded using scan sampling techniques over 26 nights from eight vessels operating out of Portland and Port Fairy on the southwest coast of Victoria. Seals were observed on all nights but none were recorded in 30% of all (777) scan observations. Of the seals attending vessels at any one time (1.89 ± 0.24), 67% were involved in activities unrelated to jigging operations with the most common behaviour category being resting/grooming. Only 3.6% of observations involved seals targeting squid caught on jig lures whereas a further 29% were of foraging on squid within 40 m of the vessel. Damage to fishing gear attributable to seals was recorded on only three occasions. There was no evidence of negative impacts on seals from vessel operations. The majority of seals foraging on squid around vessels were adult females (71%) with the remainder being almost exclusively juvenile males. The current level of interactions between Australian fur seals and vessels in the SSJF appears minor.

Adolescence and abuse : trauma and the socio-sexual abject in John Duigans lawn dogs

The article analyzes the presentation of youth in the film "Lawn Dogs," directed by John Duigan. In the film, the child as victim is defined by socio-economic contexts. The author explores the discursive moves by which means the film witnesses or occludes the traumatic experiences suffered by the child and adolescent characters, and how far it articulates a satiric revision of social hierarchies that construct generational identities of gender and class.

Sexing accuracy and indicators of maturation status in captive Murray cod Maccullochella peelii peelii using non-invasive ultrasonic imagery

Macroscopic- and histological-based assessments of gonad condition were compared with ultrasound images to determine the feasibility of this technology as a non-invasive diagnostic tool for identifying sex and assessing maturation status of Murray cod. Four age-classes (1⁺, 2⁺, 3⁺ and 6⁺ years), were sub-sampled at monthly intervals throughout their annual reproductive cycle and scanned with a 5 MHz linear transducer. An interpretation of sex was made from the resulting images and maximum cross-sectional gonad diameter and area were recorded. Fish were subsequently dissected to confirm gender, and the weights and maturation status of gonads determined and then compared with their respective image profile. Ovaries of females were usually a distinctive feature in ultrasound images, being particularly obvious in older and/or more developed fish. In contrast, the identification of male testis was more problematic. Nonetheless, identifying sex from ultrasound images was consistently achieved by recording the presence/absence of a female ovary (96% total sexing accuracy). Maximum cross-sectional ovary diameter and area were highly correlated with gonad weight (r² = 0.90 and 0.89, respectively) suggesting that indices of maturation status, comparable to the gonadosomatic index (GSI), can be obtained non-destructively from ultrasound scans of females. A less distinct relationship occurred between these dimensions and weight of testes (r² = 0.41). Significant increases (P < 0.05) in mean gonad index (GI, calculated from gonad diameter) occurred for most gonad development stages. However, differences in mean GI between maturation stages were confounded by phenotypic variability, indicating that GI may be limited to population level studies. Nevertheless, ultrasound images of ovaries at each development stage were visually distinctive and enabled qualitative evaluations of maturity, thereby complementing quantitative GI assessments. Repeated serial-monitoring of the same population using ultrasound appears to have great potential for tracking maturation-induced changes in broodfish.

The SF36 Version 2: critical analyses of population weights, scoring algorithms and population norms

Background: The SF36 Version 2 (SF36V2) is a revision of the SF36 Version 1, and is a widely used health status measure. It is important that guidelines for interpreting scores are available.

Method: A population sample of Australians (n = 3015) weighted to achieve representativeness was administered the SF36V2. Comparisons between published US weights and sample derived weights were made, and Australian population norms computed and presented.

Major findings: Significant differences were observed on 7/8 scales and on the mental health summary scale. Possible causes of these findings may include different sampling and data collection procedures, demographic characteristics, differences in data collection time (1998 vs. 2004), differences in health status or differences in cultural perception of the meaning of health. Australian population norms by age cohort, gender and health status are reported by T-score as recommended by the instrument developers. Additionally, the proportions of cases within T-score deciles are presented and show there are important data distribution issues.

Principal conclusions: The procedures reported here may be used by other researchers where local effects are suspected. The population norms presented may be of interest. There are statistical artefacts associated with T-scores that have implications for how SF36V2 data are analysed and interpreted.

Efficacy and safety of vertebroplasty for treatment of painful osteoporotic vertebral fractures: a randomised controlled trial [ACTRN012605000079640]

Background: Vertebroplasty is a promising but as yet unproven treatment for painful osteoporotic vertebral fractures. It involves radiographic-guided injection of various types of bone cement directly into the vertebral fracture site. Uncontrolled studies and two controlled quasi-experimental before-after studies comparing volunteers who were offered treatment to those who refused it, have suggested an early benefit including rapid pain relief and improved function. Conversely, several uncontrolled studies and one of the controlled before-after studies have also suggested that vertebroplasty may increase the risk of subsequent vertebral fractures, particularly in vertebrae adjacent to treated levels or if cement leakage into the adjacent disc has occurred. As yet, there are no completed randomised controlled trials of vertebroplasty for osteoporotic vertebral fractures. The aims of this participant and outcome assessor-blinded randomised placebo-controlled trial are to i) determine the short-term efficacy and safety (3 months) of vertebroplasty for alleviating pain and improving function for painful osteoporotic vertebral fractures; and ii) determine its medium to longer-term efficacy and safety, particularly the risk of further fracture over 2 years.

Design: A double-blind randomised controlled trial of 200 participants with one or two recent painful osteoporotic vertebral fractures. Participants will be stratified by duration of symptoms (< and ≥ 6 weeks), gender and treating radiologist and randomly allocated to either the treatment or placebo. Outcomes will be assessed at baseline, 1 week, 1, 3, 6, 12 and 24 months. Outcome measures include overall, night and rest pain on 10 cm visual analogue scales, quality of life measured by the Assessment of Quality of Life, Osteoporosis Quality of Life and EQ-5D questionnaires; participant perceived recovery on a 7-point ordinal scale ranging from 'a great deal worse' to 'a great deal better'; disability measured by the Roland-Morris Disability Questionnaire; timed 'Up and Go' test; and adverse effects. The presence of new fractures will be assessed by radiographs of the thoracic and lumbar spine performed at 12 and 24 months.

Discussion: The results of this trial will be of major international importance and findings will be immediately translatable into clinical practice.
