Background There is growing recognition among public health circles of the need for regulatory action for overweight and obesity, but there has been limited research into whether the Australian public supports government intervention. This study aimed to determine the level of public support for food-related regulations for obesity, and to assess the determinants of support. Methods A nationally representative sample of Australian adults ( n  = 2011) was recruited by market research company Online Research Unit to complete an online survey. The survey measured respondents’ perception of the obesity problem in Australia, and level of agreement on a 5-point Likert scale (strongly disagree to strongly agree) with proposed regulations in three domains; advertising, sponsorship of children’s sport, and taxation. Binary logistic regression models were run to examine the association between demographic variables and support for regulation. Results The majority of respondents (92.5%) considered overweight and obesity to be a somewhat or very serious problem in Australia, and almost 90% felt there should be at least some government regulation to protect the public. Respondents agreed that the government should regulate food and beverage advertising (69.5%), with strongest support for restricting unhealthy food advertising to children (78.9%). There was lower support for prohibiting unhealthy food and beverage company sponsorship of children’s sport (63.4% agreement), and for taxing sugar-sweetened beverages (54.5%), although the majority were still in favour. Support for fiscal policies slightly increased if revenue was to be used for health purposes. Females and tertiary educated respondents showed stronger agreement with proposed regulations ( p  < 0.05). Conclusions The survey findings suggest the majority of the Australian population recognises obesity to be a serious health problem, and support government regulation of the food environment as a population-level preventative strategy.

Background Increased marketing of energy-dense, nutrient-poor foods has been identified as a driver of the global obesity epidemic and a priority area for preventative efforts. Local and international research has focused on the unhealthiness of television advertising, with limited research into the growing outdoor advertising industry. This study aimed to examine the extent of food and beverage advertising on the Sydney metropolitan train network, and to assess the nutritional quality of advertised products against the Australian Guide to Healthy Eating. Methods All 178 train stations on the Sydney metropolitan train network were surveyed in summer and winter. A survey tool was developed to collect information for all advertisements on and immediately surrounding the train station. Information included product, brand, location and advertisement format. Advertisements were coded by nutrition category, product subcategory and size. Chi-square, ANOVA and ANCOVA tests were conducted to test for differences in the amount of food and beverage advertising by season and area socioeconomic status (SES). Results Of 6931 advertisements identified, 1915 (27.6%) were promoting a food or beverage. The majority of food and beverage advertisements were for unhealthy products; 84.3% were classified as discretionary, 8.0% core and 7.6% miscellaneous. Snack foods and sugar-sweetened beverages were the most frequently advertised products, regardless of season. Coca-Cola and PepsiCo were the largest advertisers on the network, contributing 10.9% and 6.5% of total advertisements respectively. There was no difference in the mean number of food and beverage advertisements by area SES, but the proportion of advertising that was for discretionary foods was highest in low SES areas (41.9%, p  < 0.001). Conclusions The results indicate that, irrespective of season, food and beverage advertisements across the Sydney metropolitan train network are overwhelmingly for unhealthy (discretionary) products. The results of this study highlight the inadequacy of Australia’s voluntary self-regulatory system in protecting members of the public from exposure to unhealthy food advertising. Regulatory action by government, such as placing a cap on the amount of unhealthy food advertisements, or requiring a proportion of all advertising to be for the promotion of healthy foods, is required to address this issue.

Abstract Aims To investigate whether long-term glycemic variability (GV) is associated with vascular complication development in type 2 diabetes. Methods In a post hoc FIELD trial analysis, GV was calculated as the standard deviation and coefficient of variation (CV) of glycated hemoglobin A1c (HbA1c) and fasting plasma glucose. Baseline variables were compared across quartiles of on-study variability by chi square and ANOVA. Prospective associations between baseline to 2-year GV and subsequent vascular and mortality outcomes were analyzed using landmark logistic and Cox proportional hazards regression. Results Baseline factors associated with higher on-study GV included younger age, male gender, longer diabetes duration, and higher pharmacological therapies usage. Both HbA1c and fasting glucose CV were associated with increased risk of microvascular complications (HR 1.02 [95% CI, 1.01-1.03] P < 0.01; and HR 1.01 [95% CI, 1.00-1.01] P < 0.001, respectively). HbA1c and fasting glucose CV were associated with increased cardiovascular disease (HR 1.02 [95% CI, 1.00-1.04]; and HR 1.01 [95% CI, 1.00-1.02], both P < 0.05). HbA1c CV associated with increased stroke (HR 1.03 [95% CI, 1.01-1.06) P < 0.01). Glucose CV associated with increased coronary events (HR 1.01 [95% CI, 1.00-1.02] P < 0.05). Both HbA1c and glucose CV associated with increased total mortality (HR 1.04 [95% CI, 1.02-1.06]; and HR 1.01 [95% CI, 1.01-1.02], both P < 0.001) and noncardiovascular mortality (HR 1.05 [95% CI, (1.03-1.07]; and HR 1.02 [95% CI, 1.01-1.03], both P < 0.001). HbA1c CV associated with coronary mortality (HR 1.04 [95% CI, 1.01-1.07] P < 0.05). Conclusions Long-term GV was associated with increased risk of vascular outcomes in type 2 diabetes.

The UN High-Level Meeting on Non-Communicable Diseases (NCDs) in September, 2011, is an unprecedented opportunity to create a sustained global movement against premature death and preventable morbidity and disability from NCDs, mainly heart disease, stroke, cancer, diabetes, and chronic respiratory disease. The increasing global crisis in NCDs is a barrier to development goals including poverty reduction, health equity, economic stability, and human security. The Lancet NCD Action Group and the NCD Alliance propose five overarching priority actions for the response to the crisis—leadership, prevention, treatment, international cooperation, and monitoring and accountability—and the delivery of five priority interventions—tobacco control, salt reduction, improved diets and physical activity, reduction in hazardous alcohol intake, and essential drugs and technologies. The priority interventions were chosen for their health effects, cost-effectiveness, low costs of implementation, and political and financial feasibility. The most urgent and immediate priority is tobacco control. We propose as a goal for 2040, a world essentially free from tobacco where less than 5% of people use tobacco. Implementation of the priority interventions, at an estimated global commitment of about US$9 billion per year, will bring enormous benefits to social and economic development and to the health sector. If widely adopted, these interventions will achieve the global goal of reducing NCD death rates by 2% per year, averting tens of millions of premature deaths in this decade.

To determine sex and age differences in the use of medications for diabetes and cardiovascular risk factors in people with diabetes in Australia. Pharmaceutical claims data of participants in the 45 and Up Study who self-reported having diabetes before 2013, were alive on 1.sup.st January 2013 and had at least one medication dispensing record between 1.sup.st January 2013 and 31.sup.st December 2019 were analysed. Annual sex and age-specific percentages of participants supplied specific medications were estimated for years 2013 to 2019. Percentages were reported for any glucose lowering medications and by drug class, any lipid modifying agents, and any blood pressure lowering medications. Altogether 25,733 participants (45.2% women) with diabetes were included. The percentage of participants who were supplied with glucose lowering medications was consistently lower in women compared to men. In both sexes, the percentage of participants who were supplied with glucose lowering medications was lowest among those aged [greater than or equal to]75 years and this decreased over time. Similar findings were observed for lipid modifying agents and blood pressure lowering medications. The use of sodium glucose co-transporter 2 inhibitors increased substantially in participants aged <75 years since it became available in 2013. However, no sex differences were observed in its use among people with hospital-recorded history of cardiovascular disease. Practitioners should be aware of possible sex disparities in the pharmacological treatment of diabetes and cardiovascular risk factors in people with diabetes in Australia. There is a possible time lag between reporting of research findings and uptake of sodium glucose co-transporter 2 inhibitors prescribing in individuals with diabetes and high cardiovascular risk in clinical practice, nevertheless, the result observed was consistent with the management guidelines at the time of the study.

Background Public health bodies in Australia remain concerned about marketing of unhealthy commodities; namely unhealthy food, alcohol and gambling products. Children are particularly susceptible to the influence of unhealthy commodity marketing. This study explored adults’ perceptions of unhealthy commodities sponsorship in elite sport and policies to restrict them. Methods Four focus groups of 7–8 frequent sport spectators were recruited, including parents and non-parents, and located in inner and outer suburbs of Sydney, Australia. Results were analysed thematically. Results Participants identified the contradictions of healthy messages of sport and unhealthy commodities, while highlighting the commercial value of sport sponsorship to sporting clubs. There is concern around children’s exposure to effective and integrated marketing techniques when viewing sport, which encouraged unhealthy habits. Support for restricting sponsorship related to perceived product harm, with gambling viewed as having the greatest health impact. Participants were supportive of policies that reduced exposure of unhealthy commodities to children, but were concerned about the financial risk to sporting clubs. Governments and sports associations were identified as holding responsibility for enacting changes. Conclusion A number of options were identified for advocates to gain public and political traction to reduce unhealthy commodity sponsorship. There is potential for shifts away from unhealthy sponsorship by both governments and sports associations.

Background Timely referral and diagnosis of Juvenile Idiopathic Arthritis (JIA) by a pediatric rheumatologist ensures early intervention to minimize long-term joint damage and disability. This study aimed to quantify the impact of delays in diagnosis on health service use, health-related quality of life (HRQoL) and associated costs to the health system. Methods A cost-utility analysis was conducted over a lifetime horizon from a health funder perspective in 2023 Australian dollars, comparing time from actively seeking treatment to formal diagnosis (< 6 months, 6 + months). Time to diagnosis, healthcare use, including medical investigations, health professional visits, hospitalizations and medications, was determined using The IMPACT Survey. Incremental costs were estimated by applying Australian government subsidy item costs (medications), schedule fees (medical services), and National Efficient Prices (hospitalizations). HRQoL was measured using Child Health Utility Instrument (CHU9D). Incremental Quality Adjusted Life Years (QALYs) were estimated using participants’ CHU9D utility values based on Australian preference weights and life expectancy. Costs and QALYs were present valued at 5% per annum. Sensitivity analyses were conducted for robustness. Results Over one-third ( n  = 61/163) of children were diagnosed 6 + months from actively seeking treatment. Compared with 6 + months, diagnosis within 6 months was associated with a lower use of health services, resulting in a mean annual decrease in costs for the healthcare funder of more than $10,000 per child. The majority of the cost savings were due to reductions in hospitalizations for pain, inflammation, and investigative procedures. There were also significant increases in HRQoL; 0.14 (95%CI 0.05, 0.23) utility value. The differences in health service use and HRQoL from timely diagnosis persisted over 20 years from diagnosis. Over a lifetime, the present value of healthcare cost savings was $208,458 (95%CI $45,388, $371,528) and the increase in HRQoL resulted in an additional 2.82 (95%CI 1.03, 4.61) QALYs per child. At a willingness to pay of $50,000 per QALY, the estimated net benefit to the health funder was $349,520 (95%CI $139,630, $559,411) per child. Conclusions Interventions to improve the time to diagnosis of JIA within six months are likely cost-effective and can significantly improve HRQoL for people living with JIA.

Brand-Miller, Human Nutrition Unit, School of Molecular and Microbial Biosciences, University of Sydney, NSW 2006 Australia. E-mail: j.brandmiller{at}mmb.usyd.edu.au Abstract OBJECTIVE —The use of diets with low glycemic index (GI) in the management of diabetes is controversial, with contrasting recommendations around the world. We performed a meta-analysis of randomized controlled trials to determine whether low-GI diets, compared with conventional or high-GI diets, improved overall glycemic control in individuals with diabetes, as assessed by reduced HbA 1c or fructosamine levels. RESEARCH DESIGN AND METHODS —Literature searches identified 14 studies, comprising 356 subjects, that met strict inclusion criteria. All were randomized crossover or parallel experimental design of 12 days’ to 12 months’ duration (mean 10 weeks) with modification of at least two meals per day. Only 10 studies documented differences in postprandial glycemia on the two types of diet. RESULTS —Low-GI diets reduced HbA 1c by 0.43% points (CI 0.72–0.13) over and above that produced by high-GI diets. Taking both HbA 1c and fructosamine data together and adjusting for baseline differences, glycated proteins were reduced 7.4% (8.8–6.0) more on the low-GI diet than on the high-GI diet. This result was stable and changed little if the data were unadjusted for baseline levels or excluded studies of short duration. Systematically taking out each study from the meta-analysis did not change the CIs. CONCLUSIONS —Choosing low-GI foods in place of conventional or high-GI foods has a small but clinically useful effect on medium-term glycemic control in patients with diabetes. The incremental benefit is similar to that offered by pharmacological agents that also target postprandial hyperglycemia.

To assess the effects of early management of hyperglycaemia with antidiabetic drugs plus lifestyle intervention compared with lifestyle alone, on microvascular function in adults with pre-diabetes. Trial design: International, multicenter, randomised, partially double-blind, placebo-controlled, clinical trial. Males and females aged 45-74 years with IFG, IGT or IFG+IGT, recruited from primary care centres in Australia, Austria, Bulgaria, Greece, Kuwait, Poland, Serbia, Spain and Turkey. Participants were randomized to placebo; metformin 1.700 mg/day; linagliptin 5 mg/day or fixed-dose combination of linagliptin/metformin. All patients were enrolled in a lifestyle intervention program (diet and physical activity). Drug intervention will last 2 years. Primary Outcome: composite end-point of diabetic retinopathy estimated by the Early Treatment Diabetic Retinopathy Study Score, urinary albumin to creatinine ratio, and skin conductance in feet estimated by the sudomotor index. Secondary outcomes in a subsample include insulin sensitivity, beta-cell function, biomarkers of inflammation and fatty liver disease, quality of life, cognitive function, depressive symptoms and endothelial function. One thousand three hundred ninety one individuals with hyperglycaemia were assessed for eligibility, 424 excluded after screening, 967 allocated to placebo, metformin, linagliptin or to fixed-dose combination of metformin + linagliptin. A total of 809 people (91.1%) accepted and initiated the assigned treatment. Study sample after randomization was well balanced among the four groups. No statistical differences for the main risk factors analysed were observed between those accepting or rejecting treatment initiation. At baseline prevalence of diabetic retinopathy was 4.2%, severe neuropathy 5.3% and nephropathy 5.7%. ePREDICE is the first -randomized clinical trial with the aim to assess effects of different interventions (lifestyle and pharmacological) on microvascular function in people with pre-diabetes. The trial will provide novel data on lifestyle modification combined with glucose lowering drugs for the prevention of early microvascular complications and diabetes. - ClinicalTrials.Gov Identifier: NCT03222765 - EUDRACT Registry Number: 2013-000418-39.

Background Microvascular disease is associated with a high risk of macrovascular events in patients with type 2 diabetes, but the impact of macrovascular disease on the risk of microvascular events remains unknown. We sought to evaluate the respective effects of prior microvascular and macrovascular disease on the risk of major outcomes, including microvascular events, in these patients. Methods Participants in the Action in Diabetes and Vascular Disease: PreterAx and DiamicroN Modified-Release Controlled Evaluation (ADVANCE) trial (n = 11,140) and the ADVANCE-ON post-trial study (n = 8494) were categorized into 4 groups at baseline: dual absence of microvascular or macrovascular disease (n = 6789), presence of microvascular disease alone (n = 761), macrovascular disease alone (n = 3196), and both (n = 394). Outcomes were all-cause mortality, major macrovascular events (MACE), and major clinical microvascular events. Results All-cause mortality, MACE, and major clinical microvascular events occurred in 2265 (20%), 2166 (19%), and 807 (7%) participants respectively, during a median follow-up of 9.9 (inter-quartile interval 5.6–10.9) years. The adjusted hazard ratios [95% CI] of death, MACE, and major clinical microvascular events were each greater in patients with baseline microvascular disease (1.43 [1.20–1.71], 1.64 [1.37–1.97], and 4.74 [3.86–5.82], respectively), macrovascular disease (1.43 [1.30–1.57], 2.04 [1.86–2.25], and 1.26 [1.06–1.51]) or both (2.01 [1.65–2.45], 2.92 [2.40–3.55], and 6.30 [4.93–8.06]) compared with those without these conditions. No interaction was observed between baseline microvascular and macrovascular disease for these events. The addition of microvascular disease (change in c-statistic [95% CI] 0.005 [0.002–0.008], p = 0.02) or macrovascular disease (0.005 [0.002–0.007], p < 0.0001) considered separately or together (0.011 [0.007–0.014], p < 0.0001) improved the discrimination and the classification (integrated discrimination improvement (IDI): 0.013 [0.010–0.016], p < 0.001; net reclassification improvement (NRI): 0.021 [0.011–0.032], p < 0.001) of the risk of all-cause mortality. Microvascular disease improved discrimination (0.009 [0.003–0.014]) and classification (IDI: 0.008 [0.006–0.010]; NRI: 0.011 [0.001–0.020]) of MACE. Baseline macrovascular disease modestly enhanced IDI (0.002 [0.001–0.002]) and NRI (0.041 [0.002–0.087]), but not discrimination, of major clinical microvascular events. Conclusions Microvascular and macrovascular disease are independently associated with the 10-year risk of death, MACE, and major clinical microvascular events in patients with type 2 diabetes. The coexistence of these conditions was associated with the highest risks.
