Developing standardized methods to assess cost of healthy and unhealthy (current) diets in Australia

Unhealthy diets contribute at least 14% to Australia's disease burden and are driven by ‘obesogenic’ food environments. Compliance with dietary recommendations is particularly poor amongst disadvantaged populations including low socioeconomic groups, those living in rural/remote areas and Aboriginal and Torres Strait Islanders. The perception that healthy foods are expensive is a key barrier to healthy choices and a major determinant of diet-related health inequities. Available state/regional/local data (limited and non-comparable) suggests that, despite basic healthy foods not incurring GST, the cost of healthy food is higher and has increased more rapidly than unhealthy food over the last 15 years in Australia. However, there were no nationally standardised tools or protocols to benchmark, compare or monitor food prices and affordability in Australia. Globally, we are leading work to develop and test approaches to assess the price differential of healthy and less-healthy (current) diets under the food price module of the International Network for Food and Obesity/non-communicable diseases (NCDs) Research, Monitoring and Action Support (INFORMAS). This presentation describes contextualization of the INFORMAS approach to develop standardised Australian tools, survey protocols and data collection and analysis systems. The ‘healthy diet basket’ was based on the Australian Foundation Diet, 1 The ‘current diet basket’ and specific items included in each basket, were based on recent national dietary survey data.2 Data collection methods were piloted. The final tools and protocols were then applied to measure the price and affordability of healthy and less healthy (current) diets of different household groups in diverse communities across the nation. We have compared results for different geographical locations/population subgroups in Australia and assessed these against international INFORMAS benchmarks. The results inform the development of policy and practice, including those relevant to mooted changes to the GST base, to promote nutrition and healthy weight and prevent chronic disease in Australia.

Symposium: Food pricing and affordability of ‘healthy’ versus ‘less healthy’ diets: An international approach to monitoring and surveillance

Symposium co-ordinated by The International Network for Food and Obesity/NCDs Research, Monitoring and Action Support (INFORMAS) Purpose Global monitoring of the price and affordability of foods, meals and diets is urgently needed. There are major methodological challenges in developing robust, cost-effective, standardized, and policy relevant tools, pertinent to nutrition, obesity, and diet-related non-communicable diseases and their inequalities. There is increasing pressure to take into account environmental sustainability. Changes in price differentials and affordability need to be comparable between and within countries and over time. Robust tools could provide baseline data for monitoring and evaluating structural, economic and social policies at the country/regional and household levels. INFORMAS offers one framework for consideration.

Healthy start: Closing the gap on Indigenous childhood obesity

We’ve recently seen some encouraging improvements in closing the gap on Indigenous disadvantage: better educational outcomes, higher child immunisation rates, more health checks, and a 35% drop in the gap between Indigenous and non-Indigenous child deaths. But Aboriginal and Torres Strait Islander people continue to suffer a much greater burden of ill-health than other Australians. The gap in Indigenous life expectancy at birth remains unacceptably high at 10.6 years for men and 9.5 years for women. Three-quarters of Indigenous deaths are from potentially avoidable causes. These include preventable conditions such as type 2 diabetes, cardiovascular disease and some cancers. A major contributor to these preventable conditions is excess body weight.

Healthy waterways social science research report 2015

Healthy Waterways aims to protect and enhance the condition of waterways across 19 catchment local government areas in Queensland. It does this by seeking to influence the decisions and actions – including social lifestyle choices – of community members who interact with these waterways. It then monitors the waterways in the 19 catchments to gauge the impact of these decisions and actions. Each year, Healthy Waterways produces a report on its activities and their impact on the condition of the waterways they are monitoring. This research will contribute to understanding the social component of that report, specifically the attitudinal and behavioural components that underpin social expectations and actions towards protecting and supporting local waterways in communities across the 19 catchment local government areas in Queensland.

Prevalence and analysis of t(14;18) and t(11;14) chromosomal translocations in healthy Indian population

Hematopoietic malignancies like leukemia and lymphoma are characteristically associated with various chromosomal translocations. Follicular lymphoma (FL) and mantle cell lymphoma (MCL) are two subtypes of non-Hodgkin's lymphoma which possess t(14;18) and t(11;14) translocations, respectively. The incidence of FL and MCL is higher in the western countries as compared to India. Interestingly, the associated translocations are also found in healthy individuals in western population, which is 50-80% for t(14;18), whereas t(11;14) occurs at a very low frequency. However, there are no studies to explore thes translocations in healthy Indian population, which could explain the lower incidence of FL and MCL. We employed Southern hybridization following nested PCR to detect above translocations in healthy individuals from India. Our results suggest that this assay can detect one t(14;18) translocation event in up to 10(7) normal cells where as one t(11;14) in 10(8) normal cells. According to our results, 87 out of 253 individuals carry t(14;18) indicating 34% prevalence in the population. The presence of this translocation was also detectable at the transcript level. Although, no gender-based difference was observed, an age-dependent increase in the prevalence of translocation was found in adults. However, even after studying 210 people, we could not detect any t(11;14) translocation, indicating that it is uncommon in Indian population. These results suggest that lower incidence of FL and MCL in India could be attributed to lower prevalence of these translocations in healthy individuals.

Early life determinants of atopy : A 20-year prospective follow-up study on unselected, healthy newborns

Atopy-related allergic diseases, i.e. allergic rhinoconjunctivitis, atopic dermatitis and asthma, have increased in frequency in the industrialized countries. In order to reverse this trend, effective preventive strategies need to be developed. This requires a better understanding of the early-life events leading to the expression of the atopic phenotype. The present study has aimed at defining early-life factors and markers associated with the subsequent development of allergic diseases in a cohort of 200 healthy, unselected Finnish newborns prospectively followed up from birth to age 20 years. Their mothers were encouraged to start and maintain exclusive breastfeeding as long as it was nutritionally sufficient for the infant. Consequently, all the infants received some duration of exclusive breastfeeding, 58% of the infants were on exclusive breastfeeding for the first 6 months of life, and 18% received this feeding at least for the first 9 months. Of the infants, 42% had a family history of allergy. After the first year of follow-up, the children were re-assessed at ages 5, 11 and 20 years with clinical examination, skin prick testing, and parental and personal interviews. Exclusive breastfeeding for over 9 months was associated with atopic dermatitis and symptoms of food hypersensitivity at age 5 years, and with symptoms of food hypersensitivity at age 11 years in the children with a familial allergy. Subjects with allergic symptoms or a positive skin prick test in childhood or adolescence had lower retinol concentrations during their infancy and childhood than others. An elevated cord serum immunoglobulin E concentration predicted subsequent atopic manifestations though with modest sensitivity. Children and adolescents with allergic symptoms, skin prick test positivity and an elevated IgE had lower total cholesterol levels in infancy and childhood than the nonatopic subjects. In conclusion, prolonging strictly exclusive breastfeeding for over 9 months of age was not of help in prevention of allergic symptoms; instead, it was associated with increased atopic dermatitis and food hypersensitivity symptoms in childhood. Due to the modest sensitivity, cord serum IgE is not an effective screening method for atopic predisposition in the general population. Retinol and cholesterol concentrations in infancy were inversely associated with the subsequent development of allergic symptoms. Based on these findings, it is proposed that there may be differences in the inborn regulation of retinol and cholesterol levels in children with and without a genetic susceptibility to atopy, and these may play a role in the development of atopic sensitization and allergic diseases.

Process makes perfect: High-performance design creates healthy environments for high-performance learning

Considering the staggering benefits of high-performance schools, it seems an obvious choice to “go green.” High-performance schools offer an exceptionally cost-effective means to enhance student learning, using on average 33 percent less energy than conventionally designed schools, and provide substantial health gains, including reduced respiratory problems and absenteeism. According to the 2006 study, Greening America's Schools, Costs and Benefits, co-sponsored by the American Institute of Architects (AIA) and Capital E, a green building consulting firm, high-performance lighting is a key element of healthy learning environments, contributing to improved test scores, reduced off-task behavior, and higher achievement among students. Few argue this point more convincingly than architect Heinz Rudolf, of Portland-Oregon-based Boora Architects, who has designed sustainable schools for more than 80 school districts in Oregon, Washington, Colorado, and Wyoming, and has pioneered the high-performance school movement. Boora's recently completed project, the Baker Prairie Middle School in Canby, Oregon is one of the most sustainable K-12 facilities in the state, and illustrates Rudolf's progressive and research-intensive approach to school design.

The hard work of leisure: Healthy life, activewear and Lorna Jane

Since the 2000s activewear has grown as a fashion category, and the tropes of gym wear – leggings, leotards and block colours – have become fashionable attire for both men and women outside the gym. This article examines the rise of activewear in the context of an on-going dialogue between fashion and sport since the beginning of the twentieth century. Through an analysis of the Australian activewear label, Lorna Jane, we consider the fashionable female body as both the object and subject of a consumer culture that increasingly overlays leisure with fashion. Activewear can be seen as the embodiment of an active and fashionable lifestyle that is achieved through a regime of self-discipline, and that symbolizes the pleasure in attaining and displaying the healthy and fit body.

Long-term effects of physical activity level on changes in healthy body mass index over 12 years in young adult women

Objectives To examine the effects of overall level and timing of physical activity (PA) on changes from a healthy body mass index (BMI) category over 12 years in young adult women. Patients and Methods Participants in the Australian Longitudinal Study on Women's Health (younger cohort, born 1973-1978) completed surveys between 2000 (age 22-27 years) and 2012 (age 34-39 years). Physical activity was measured in 2000, 2003, 2006, and 2009 and was categorized as very low, low, active, or very active at each survey, and a cumulative PA score for this 9-year period was created. Logistic regression was used to examine relationships between PA accumulated across all surveys (cumulative PA model) and PA at each survey (critical periods PA model), with change in BMI category (from healthy to overweight or healthy to obese) from 2000 to 2012. Results In women with a healthy BMI in 2000, there were clear dose-response relationships between accumulated PA and transition to overweight (P=.03) and obesity (P<.01) between 2000 and 2012. The critical periods analysis indicated that very active levels of PA at the 2006 survey (when the women were 28-33 years old) and active or very active PA at the 2009 survey (age 31-36 years) were most protective against transitioning to overweight and obesity. Conclusion These findings confirm that maintenance of very high PA levels throughout young adulthood will significantly reduce the risk of becoming overweight or obese. There seems to be a critical period for maintaining high levels of activity at the life stage when many women face competing demands of caring for infants and young children.

A submission to the Tasmanian Department of Health and Human Services consultation “Healthy Tasmania Five Year Strategic Plan”

This submission will address a number of questions raised in section 5.2, “Potential Future Initiatives to target smoking”, of the Healthy Tasmania Five Year Strategic Plan – Community Consultation Draft. Each question has been answered within this submission. This submission will also address the possibility of legal challenges to these proposed changes, a pivotal consideration when implementing any tobacco control laws. This is due to the aggressive nature of the tobacco industry, as illustrated by their attempts to challenge plain packaging laws in the country and through international treaties. The evidence provided in my submission illustrates that prevention of initiation of smoking during adolescence has various benefits in terms of reduction of negative smoking behaviors in later life. I argue that increasing the minimum legal age of purchasing for tobacco to 21 will benefit both the levels of underage smoking as well as the age of onset of initiation of smoking, due to the greater difficulties that those who are underage would experience in accessing tobacco products. I will also address the question of whether the minimum smoking age should be increased to 25.

Determination of intestinal permeability in healthy horses using the contrast medium iohexol

Tämä lisensiaatin tutkielma koostuu kolmesta osasta; kirjallisuuskatsauksesta, kokeellisesta osasta ja liitteistä. Iohexol on ionisoitumaton, trijodattu ja vesiliukoinen röntgenvarjoaine. Iohexolia on hyödynnetty lääketieteessä useita vuosia. Iohexolia on käytetty muun muassa angio- ja myelografiassa, lisäksi iohexolia on hyödynnetty arvioitaessa munuaiskerästen suodattumisnopeutta sekä suoliston läpäisevyyden muutoksia. Hevosen tulehduksellisessa suolistosairaudessa (Inflammatory bowel disease, IBD) suoliston rakenne ja sen läpäisevyys muuttuu; tyypillistä on tulehdussolujen kertyminen suoliston seinämään ja myös sidekudosmuodostusta saattaa esiintyä. Suolisto muutoksia saatetaan havaita sekä ohut- että paksusuolessa. IBD aiheuttaa hevoselle laihtumista, johtuen ravintoaineiden puutteellisesta imeytymisestä ja proteiinien menetyksestä suoleen suoliston häiriötilan yhteydessä. Tällä hetkellä IBD:n diagnostiikka perustuu tyypillisiin oireisiin, kliiniseen tutkimukseen, verinäytteisiin, glukoosin imeytymistestiin ja peräsuolesta otettuun koepalaan. IBD:n diagnostiikka on kuitenkin erittäin haastavaa ja tutkimusmenetelmiin liittyy lukuisia ongelmia, jotka vähentävät niiden luotettavuutta IBD:n diagnostiikassa. Tutkimuksemme tarkoituksena on kehittää hevosen IBD:n diagnostiikkaa entistä helpompaan, luotettavampaan ja turvallisempaan suuntaan. Tämän alustavan tutkimuksen tavoitteet olivat: (1) tutkia voidaanko iohexol havaita hevosen seerumissa oraalisen annostelun jälkeen ja (2) muodostaa iohexolin pitoisuuskuvaaja ajan funktiona terveillä hevosilla. Materiaalimme koostui kymmenestä terveestä hevosesta, joilla ei ollut havaittu laihtumista tai ripulia. Ennen iohexolin annostelua hevosille suoritettiin kliininen tutkimus ja verinäytteet otettiin maha-suolikanavan sairauden poissulkemiseksi. Hevosille suoritettiin myös mahalaukun tähystys. 16 tunnin paaston jälkeen 1 ml/kg Iohexolia annosteltiin 10 % -liuoksena nenämahaletkulla suoraan mahaan ja verinäytteet otettiin 0, 30, 60, 120, 180, 240, 300 ja 360 minuuttia annostelun jälkeen. Iohexolin pitoisuus määritettiin käyttämällä korkean erotuskyvyn nestekromatografiaa. Iohexolin pitoisuuksista tietyillä ajanhetkillä muodostettiin kuvaaja. Hevosilla ei havaittu maha-suolikanavan sairauksia. Kaikki hevoset olivat hyvässä kuntoluokassa ja mahalaukun tähystyksessä ei havaittu merkittäviä muutoksia. Verinäytteiden tulokset olivat viiterajoissa. Kaikki hevoset sietivät iohexolia hyvin ja haittavaikutuksia ei havaittu. Iohexol oli havaittavissa seerumissa 60 minuutin kuluttua annostelusta. Kuvaajassa voitiin havaita kaksi huippua. Statistiset menetelmät tukivat löydöksiä. Iohexol testi oli yksinkertainen suorittaa ja siihen ei liittynyt haittavaikutuksia. Annos 1ml/kg oli havaittavissa seerumissa. Iohexolin pitoisuuskuvaaja muodosti kaksi huippua, ja tämänkaltainen ilmiö on kuvattu kirjallisuudessa aikaisemmin useiden lääkkeiden tapauksessa. Hevosella ilmiö liittyy todennäköisesti maha-suolikanavan rakenteellisiin ja fysiologisiin eroavaisuuksiin ja lisätutkimuksia ilmiön varmistamiseksi tarvitaan. Iohexol näyttää olevan potentiaalinen merkkiaine suoliston läpäisevyyden arviointiin ja lisätutkimuksia IBD:tä sairastavien hevosten seerumin iohexolin pitoisuuksista verrattuna terveiden hevosten seerumin iohexolin pitoisuuksiin on suunnitteilla.
