Focusing on fast food restaurants alone underestimates the relationship between neighborhood deprivation and exposure to fast food in a large rural area
<p>Abstract</p> <p>Background</p> <p>Individuals and families are relying more on food prepared outside the home as a source for at-home and away-from-home consumption. Restricting the estimation of fast-food access to fast-food restaurants alone may underestimate potential spatial access to fast food.</p> <p>Methods</p> <p>The study used data from the 2006 Brazos Valley Food Environment Project (BVFEP) and the 2000 U.S. Census Summary File 3 for six rural counties in the Texas Brazos Valley region. BVFEP ground-truthed data included identification and geocoding of all fast-food restaurants, convenience stores, supermarkets, and grocery stores in study area and on-site assessment of the availability and variety of fast-food lunch/dinner entrées and side dishes. Network distance was calculated from the population-weighted centroid of each census block group to all retail locations that marketed fast food (<it>n </it>= 205 fast-food opportunities).</p> <p>Results</p> <p>Spatial access to fast-food opportunities (FFO) was significantly better than to traditional fast-food restaurants (FFR). The median distance to the nearest FFO was 2.7 miles, compared with 4.5 miles to the nearest FFR. Residents of high deprivation neighborhoods had better spatial access to a variety of healthier fast-food entrée and side dish options than residents of low deprivation neighborhoods.</p> <p>Conclusions</p> <p>Our analyses revealed that identifying fast-food restaurants as the sole source of fast-food entrées and side dishes underestimated neighborhood exposure to fast food, in terms of both neighborhood proximity and coverage. Potential interventions must consider all retail opportunities for fast food, and not just traditional FFR.</p

Compliance with children's television food advertising regulations in Australia
Extent: 6p.Background: The objective of this study was to assess the effectiveness of the Australian co-regulatory system in limiting children’s exposure to unhealthy television food advertising by measuring compliance with mandatory and voluntary regulations. An audit was conducted on food and beverage television advertisements broadcast in five major Australian cities during children’s programming time from 1st September 2010 to 31st October 2010. The data were assessed against mandatory and voluntary advertising regulations, the information contained in an industry report of breaches, and the Australian Guide to Healthy Eating. Results: During the two months of data collection there were a total of 951 breaches of the combined regulations. This included 619 breaches of the mandatory regulations (CTS) and 332 breaches of the voluntary regulations (RCMI and QSRI). Almost 83% of all food and beverages advertised during children’s programming times were for foods classified as ‘Extras’ in the Australian Guide to Healthy Eating. There were also breaches in relation to the amount of advertising repetition and the use of promotional appeals such as premium offers, competitions, and endorsements by popular children’s characters. The self-regulatory systems were found to have flaws in their reporting and there were errors in the Australian Food and Grocery Council’s compliance report. Conclusions: This audit suggests that current advertising regulations are inadequate. Regulations need to be closely monitored and more tightly enforced to protect children from advertisements for unhealthy foods.Michele Roberts, Simone Pettigrew, Kathy Chapman, Caroline Miller and Pascale Queste
Assessing the health impact of transnational corporations: a case study on McDonald’s Australia
Brookton man solves salt problem
Harry Whittington's work with interceptor banks has been very beneficial, the first were installed in during the mid to late 1950's, representing one of the biggest changes in the appearance of the Wheatbelt since clearing for agriculture began. When Mr Whittington's father took up his property 'Springhill' in 1897 it was the best country on a pastoral run stretching from Mundaring to Pingelly. By the time he took over the farm in 1942, he had an asset that was rapidly becoming a liability. Mr Whittington studied terracing in Asia and thought interceptor banks could be to Australian conditions what terracing was to Asian agriculture, with the theory to keep nutrients, water and organic matter in the soil as far up the slope as possible. In late 1978 a society to promote the banks, the Whittington Interceptor Salt Affected Land Treatment Society (WISALTS) was formed and has been busy every since. Productivity has been raised considerably on 'Springhill' since the dismal days of the 1940's and 1950's. Harry Whittington retired from active farming with the sale of his 1280 hectare 'Springhill' property at Brookton early last year, before he sold his property the success of the banks was so great that even the protein level of his wheat was generally above district averages.
This article includes an image of Harry Whittington holding up a photograph of the land in front of him when it was badly degraded.

Water scarcity and urban forests: Science and public policy lessons from a decade of drought in Adelaide, Australia
Drawing on the experience of greater metropolitan Adelaide, South Australia, Australia, the paper points to the links and gaps between science and public policy. The paper explores urban stormwater management lessons emerging from a ten-year, prolonged dry period that impacted the integrity of urban forests in the City of Adelaide. Among the questions addressed: will stormwater remain, as its historic and institutional settings suggest, a liability or can it become an asset? Who owns stormwater resources and to whom is its management vested? The paper examines these issues with consideration to the dangers of continuing to use urban forestry management practices that are not informed by science. The study concludes that a more integrated approach to urban water management can maintain the integrity of urban forests in ways that potentially enhance social amenities and economic efficiency.Mark Brindal, Randy Stringe
Combined home and school obesity prevention interventions for children: what behavior change strategies and intervention characteristics are associated with effectiveness?
This review identifies studies describing interventions delivered across both the home and school/community setting, which target obesity and weight-related nutrition and physical activity behaviors in children. Fifteen studies, published between 1998 and 2010, were included and evaluated for effectiveness, study quality, nutrition/activity content, behavior change techniques, and theoretical basis, using validated assessment tools/taxonomies. Seven studies were rated as effective. Behavior change techniques used to engage families, and techniques associated with intervention effectiveness were coded. Effective studies used about 10 behavior change techniques, compared with 6.5 in ineffective studies. Effective interventions used techniques including providing general information on behavior-health links, prompting practice of behavior, and planning for social support/social changes. Different behavior change techniques were applied in the home and school setting. The findings of this review provide novel insights into the techniques associated with intervention effectiveness that can inform the development of public health obesity prevention strategies.Gilly A.

Ingesting breakfast meals of different glycaemic load does not alter cognition and satiety in children
Background/Objectives: The effect of Glycaemic Index (GI) and Load (GL) of breakfasts on satiety and aspects of cognitive function in children is inconclusive. We aimed to assess if isocaloric breakfasts differing in GL (by replacing high-GI carbohydrate foods with dairy protein foods) acutely alter cognitive function and satiety in 10- to 12-year-old children.Subjects/Methods: A total of 39 children, aged 11.6±0.7 years with body mass index 18.9±3.0 kg/m 2 (Mean±s.e.) participated in a randomised crossover trial of three isocaloric breakfasts (1.3 MJ): high GL (HGL: 7 g protein, 9 g fat, 50 g carbohydrate, GL 33); medium GL (MGL: 14 g protein, 9 g fat, 45 g carbohydrate, GL 24) and low GL (LGL: 18 g protein, 10 g fat, 38 g carbohydrate, GL 18). Blood glucose was recorded using a continuous glucose monitor. Subjective hunger and cognitive performance were measured before and hourly after consuming the test breakfast via a computer-delivered battery. Ad libitum intake at a buffet lunch meal was measured at 3 h at the end of testing.Results: Incremental area under the glucose curve (iAUC) was significantly different with HGL>MGL>LGL (P0.001). Glucose concentrations fell below baseline after 83±6 min for HGL, 63±5 min (MGL) and 67±5 min (LGL)(P0.009). Breakfast GL did not significantly alter changes in cognitive function or self-reported satiety throughout testing. Energy intake at lunch was not significantly different between treatments (HGL 2943±168 kJ; MGL 2949±166 kJ; LGL 2993±191 kJ).Conclusions: Reducing breakfast GL by replacing carbohydrate with protein does not alter satiety or cognition over 3 h in 10- to 12-year-old children. © 2012 Macmillan Publishers Limited All rights reserved
The effect of using isomaltulose (Palatinose™) to modulate the glycaemic properties of breakfast on the cognitive performance of children
PURPOSE: Although previous research has associated the glycaemic load (GL) of a meal with cognitive functioning, typically the macro-nutrient composition of the meals has differed, raising a question as to whether the response was to GL or to the energy, nutrients or particular foods consumed. Therefore, the present study contrasted two breakfasts that offered identical levels of energy and macro-nutrients, although they differed in GL. METHODS: Using a repeated-measures, double-blind design, 75 children aged 5–11 years, from socially deprived backgrounds, attended a school breakfast club and on two occasions, at least a week apart, they consumed a meal sweetened with either isomaltulose (Palatinose™) (GL 31.6) or glucose (GL 59.8). Immediate and delayed verbal memory, spatial memory, sustained attention, reaction times, speed of information processing and mood were assessed 1 and 3 h after eating. RESULTS: The nature of the meals did not influence any measure of cognition or mood after an hour; however, after 3 h, children’s memory and mood improved after the lower-GL breakfast. If children had eaten the lower-GL meal on the second day of testing, they were able to process information faster and had better spatial memory later in the morning. CONCLUSIONS: Towards the end of a morning in school, having consumed a lower-GL breakfast resulted in better mood and aspects of cognitive functioning
