Food retail environments around rural Victorian primary Schools
Few studies examine the influence on population diets of the healthiness of food retail outlets in the areas surrounding rural schools in Australia. This exploratory cross-sectional study examined associations between food retail environments within 500m and 1 km of 106 primary schools in rural Victoria, Australia, and self-reported diet and measured weight status of grade 4(9-10yo) and grade 6(12-13yo) students (n = 3236). Few significant result…
Evaluation of an SMS Based Alcohol Intervention for Same Sex Attracted Women
Purpose The purpose of this randomized controlled trial (Trial registration ID: redacted) was to examine the feasibility, acceptability, and efficacy of the Step One program, an SMS-based alcohol intervention for same-sex attracted women (SSAW).Methods Ninety-seven SSAW who scored ≥8 on the Alcohol Use Disorders Identification Test (AUDIT) were randomly allocated to receive the Step One program (n = 47; mean age = 36.79) or a weekly message conta…
Healthy together Victoria and childhood obesity study
This trial is unregistered. The intervention itself was a policy setting delivered by government and our role was the collection of data to evaluate the effect of this natural experiment. That is, this study was not a trial from the classical point of view and we were not responsible for the intervention
Using spatial analysis to examine inequalities and temporal trends in food retail accessibility
Objective: In this paper, we examined whether there are inequalities in access to food retail (by type and healthiness) across local government areas (LGA) in Greater Melbourne and by LGA grouped based on their distance from the central business district and Growth Area designation. We also examined whether these inequalities persisted over time. Design: This is a secondary analysis of a repeated cross-sectional census of food outlets collected a…
Understanding weight status and dietary intakes among Australian school children by remoteness
Objective: To determine whether primary school children’s weight status and dietary behaviours vary by remoteness as defined by the Australian Modified Monash Model (MMM). Design: A cross-sectional study design was used to conduct secondary analysis of baseline data from primary school students participating in a community-based childhood obesity trial. Logistic mixed models estimated associations between remoteness, measured weight status and se…
Nutrition-Related Information on Alcoholic Beverages in Victoria, Australia, 2021
Alcoholic beverages sold in Australia are largely exempt from requirements to display nutrition information on packages, unlike other food and beverages. However, alcoholic beverage manufacturers can provide nutrition-related information voluntarily. This study aimed to investigate the prevalence of nutrition-related information on packaged alcoholic beverages in Australia. An in-store audit of the largest alcohol retailer in Melbourne, Australia…
Price promotions offered by quick service restaurants in Australia
Objective: To assess the price promotions offered by major quick service restaurant (QSR) chains in Australia from an obesity prevention perspective. Design: Cross-sectional audit of ten of the largest QSR chains in Australia. We collected information regarding temporary price promotions and ‘combination deals’ offered by each chain over thirteen consecutive weeks in 2019–2020. We assessed the type of promotions, the magnitude of discount, and th…
Beyond food swamps and food deserts
Objective: ‘Food deserts’ and ‘food swamps’ are food retail environment typologies associated with unhealthy diet and obesity. The current study aimed to identify more complex food retail environment typologies and examine temporal trends. Design: Measures of food retail environment accessibility and relative healthy food availability were defined for small areas (SA2s) of Melbourne, Australia, from a census of food outlets operating in 2008, 201…
Terrorism concern and persistence of negative attitudes towards Islam and Muslims
This study suggests that terrorism concerns can hinder the effect of prejudice reduction interventions based on education and outgroup knowledge. There is accordance in the literature that individuals who possess more knowledge about Muslim people and Islam are less likely to have anti‐Muslim prejudice. We conducted secondary analyses of data from a representative sample of Australians ( N = 1,267), and we found that terrorism concerns moderate t…
Hate Speech in a Telegram Conspiracy Channel During the First Year of the Covid-19 Pandemic
Research has explored how the COVID-19 pandemic triggered a wave of conspiratorial thinking and online hate speech, but little is empirically known about how different phases of the pandemic are associated with hate speech against adversaries identified by online conspiracy communities. This study addresses this gap by combining observational methods with exploratory automated text analysis of content from an Italian-themed conspiracy channel on …
The impact of a community-based intervention on weight, weight-related behaviours and health-related quality of life in primary school children in Victoria, Australia, according to socio-economic posi…
The WHO STOPS intervention had differential effects on several weight-related behaviours according to SEP, including physical activity. Similar impacts on HRQoL outcomes were found between high and low SEP groups. Importantly, the trial evaluation was not powered to detect subgroup differences. Future evaluations of CBIs should be designed with an equity lens, to understand if and how these types of interventions can benefit all community members…
Availability and placement of healthy and discretionary food in Australian supermarkets by chain and level of socio-economic disadvantage
Objective: The current study aimed to investigate availability and placement of healthy and discretionary (less healthy) food in supermarkets in Victoria, Australia, and examine variation by supermarket chain and area-level socio-economic disadvantage. Design: Cross-sectional supermarket audit. Measures included: (i) proportion of shelf space (in square metres) allocated to selected healthy and discretionary food and beverages; (ii) proportion of…
Profiling Malnutrition Prevalence among Australian Rural In-Patients Using a Retrospective Census of Electronic Medical Files over a 12-Month Period
In-patient malnutrition leads to poor outcomes and mortality, and it is largely uninvestigated in non-urban populations. This study sought to: (1) retrospectively estimate the prevalence of malnutrition as diagnosed by dietetics in the rural Australian setting; (2) establish the proportion of all patients at "nutritional risk"; and (3) explore associations between demographic and clinical factors with malnutrition diagnosis and nutritional risk. …
Food Retail Environments in Greater Melbourne 2008–2016
Obesity prevalence is inequitably distributed across geographic areas. Food environments may contribute to health disparities, yet little is known about how food environments are evolving over time and how this may influence dietary intake and weight. This study aimed to analyse intra-city variation in density and healthiness of food outlets between 2008 and 2016 in Melbourne, Australia. Food outlet data were classified by location, type and heal…
The Healthiness of Food and Beverages on Price Promotion at Promotional Displays
Supermarket environments can strongly influence purchasing decisions. Price promotions are recognised as a particularly persuasive tactic, but the healthiness of price promotions in prominent in-store locations is understudied. This study compared the prevalence and magnitude of price promotions on healthy and unhealthy food and beverages (foods) displayed at prominent in-store locations within Australian supermarkets, including analyses by super…
Do purchases of price promoted and generic branded foods and beverages vary according to food category and income level? Evidence from a consumer research panel
Associations between School Food Environments, Body Mass Index and Dietary Intakes among Regional School Students in Victoria, Australia
(1) Background: Childhood overweight and obesity is a significant and preventable problem worldwide. School environments have been suggested to be plausible targets for interventions seeking to improve the quality of children's dietary intake. The objective of this study was to determine the extent to which the current characteristics of the school food environment were associated with primary school students' dietary intake and Body Mass Index (…
Factors Associated with Physical Activity and Sedentary Behavior in Older Adults from Six Low- and Middle-Income Countries
Rising life expectancy in low- and middle-income countries (LMIC), coupled with the increasing burden of non-communicable diseases, accentuates the importance of generating information to support public health strategies. With this aim in mind, the purpose of this study was to identify correlates of physical activity and sedentary behavior in LMIC. We analyzed Wave 1 data (collected 2007−2010) from the World Health Organization’s longitudinal Stu…

HPV testing
Findings have implications for self-collection recommendations, as they show it is the preferred method when women are given the choice, even if they are not screening non-attenders. Findings also highlight the importance of incorporating women's needs/preferences in HPV screening recommendations
Vaccination coverage among children aged 13 to 59 months in Buenos Aires, Argentina, 2002
Although coverage rates for some vaccines were high, complete vaccination coverage remains low among children aged 13 to 59 months in Buenos Aires. Increasing coverage will require better access to vaccination, particularly in sections of the community with risk factors
Los jóvenes y la salud. Construcción de grupos en función de representaciones sobre salud y enfermedad
El objetivo de este trabajo fue indagar la existencia de diferentes "grupos" de jóvenes en función de sus representaciones alrededor de la salud y la enfermedad. En la construcción de estos "grupos" se busca incorporar conceptos tradicionalmente relegados al estudio de la subjetividad. Se trabajó con una encuesta cerrada que se aplicó sobre 400 jóvenes escolarizados. El procesamiento de los datos se realizó con el análisis de correspondencias múl…
