Establishing fundamental co-design principles and strategies for public health research practice
This study focuses on defining standard co-design principles and exploring strategies for their application in public health research. A secondary analysis was conducted, examining 55 studies sourced from a systematic review, employing directed content analysis to clarify co-design principles and their applications. The research followed Mayring’s model for deductive category application, resulting in the development and testing of eight standard…
Adolescent Involvement in Co‐Authoring Peer Reviewed Publications
Adolescents (10–24 years old) are increasingly being included as research partners or co‐researchers in line with the United Nations Convention on the Rights of the Child. However, there is no existing guidance that explores the nuance of how adolescents can be involved as co‐authors in peer reviewed research publications. Through this article, we reflect on our experiences co‐authoring peer reviewed publications with adolescents and support this…
Sustaining healthy food retail
Healthy food retail policies are government instruments designed to encourage healthier food and drink purchases by regulating aspects of food retail settings that influence consumer purchasing behaviour.

A purposive sample of government policies and acc…
Through deaf eyes
Deaf people are at higher suicide risk, yet little is known about the factors that contribute to this elevated risk, particularly in Australia. This research explored factors which deaf Australian adults perceived to influence their suicidal behavior. A parallel multi-methods sequential design study using a strengths-based deaf-centric approach was conducted. This incorporated qualitative interviews with deaf sign language users who reported adve…
Equalising power imbalances or a trail of broken promises? A qualitative study on engaging people with diverse lived experience of marginalisation in food policymaking in Australia
We provide a list of practical recommendations to guide more inclusive, equitable and fit-for-purpose food policymaking into the future. These recommendations seek to challenge dominant systems of discrimination by demonstrating how we can tangibly shift to ways of working that value and elevate the power of people who are often excluded from many decision-making systems, specifically when it comes to food and nutrition

When food delivery meets Big Tech
Online food delivery platforms are omnipresent in the food environment, influencing dietary behaviours through their appeal, convenience, availability, and marketing tactics. Increasingly major online food delivery platforms are entering formal partnerships with Big Tech companies, raising concerns about the growing corporate influence on food choices and public health. These strategic partnerships are likely to lead to market consolidation, incr…

Background Deaf people experience worse mental health compared to their hearing counterparts. We aimed to test the association between early life access to communication and perceived mental health among deaf adults in Australia.Methods An online cross-sectional study was conducted with deaf Australians who reported becoming deaf before the age of 5. Logistic regression models were fitted to assess the relationships between types of early life ac…
Evaluating the Nourish Network
Objectives: To evaluate the current state of the Nourish Network (NN) – a healthy food retail network, to inform future planning and improvement opportunities. Design: A qualitative study was conducted using semi-structured interviews conducted between January and April 2024, open-ended survey questions from six online surveys applied between 2019 and 2022 and a focus group with the NN Advisory Committee (NNAC) in June 2024. Thematic analysis was…
From promises to action
The healthiness of Australian food outlets available through online delivery platforms, by level of socioeconomic disadvantage and remoteness
Online food delivery platforms are an emerging but poorly understood aspect of food retail environments. We collected data via web scraping methods from the two leading online food delivery platforms in Victoria, Australia, identifying 11,154 food outlets from Menulog, and 12,939 from Uber Eats (with 21,733 unique outlets available across both platforms). Outlets were classified according to their healthiness using a tool developed with Australia…
A realist impact evaluation of a tool to strengthen equity in local government policy-making
Our study supports wider uptake of health equity impact assessments in local government policies and programs. Legislation, leadership and resources from upper-tiers of government can help increase the adoption of equity tools to reduce disparities in population health
A systems framework for implementing healthy food retail in grocery settings
Several differences were found when implementing healthy food retail in grocery compared to health promotion settings. The START-G map offers preliminary guidance for identifying and addressing commercial interests in grocery settings that currently promote less healthy foods and beverages, including by starting to address business outcomes and supplier relationships

Placing community in the driver's seat
Addressing health inequities requires both national and local-level action. In the case of COVID-19, locally-led place-based programs were instrumental in addressing vaccination inequities that resulted from implementation gaps in national and state-level universal COVID-19 vaccination programs. To prepare for future pandemics, understanding which local strategies are effective and the conditions that enable their effectiveness is crucial. We con…
Strengthening local government policies to address health inequities
Local governments have a responsibility to implement policies and programs that improve health and reduce health inequities. Local government's capacity to leverage resources, structures, processes and relationships, internally and across sectors and community, will be key to strengthening equity-oriented local government health policies and programs
Prevalence of chronic non-communicable diseases in Ethiopia
Interdisciplinary insights on the future of food systems research
Our dominant food system is a primary driver of worsening human and planetary health. Held in March 2022, the Public Health Association of Australia’s Food Futures Conference was an opportunity for people working across the food system to connect and advocate for a comprehensive, intersectoral, whole-of-society food and nutrition policy in Australia to attenuate these issues. Conference themes included food systems for local and global good; ecol…
Costing recommended (healthy) and current (unhealthy) diets in urban and inner regional areas of Australia using remote price collection methods

Streamlined data-gathering techniques to estimate the price and affordability of healthy and unhealthy diets under different pricing scenarios
Objective: To determine the reliability of streamlined data-gathering techniques for examining the price and affordability of a healthy (recommended) and unhealthy (current) diet. We additionally estimated the price and affordability of diets across socio-economic areas and quantified the influence of different pricing scenarios. Design: Following the Healthy Diets Australian Standardised Affordability and Pricing (ASAP) protocol, we compared a c…
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
Price Promotions by Food Category and Product Healthiness in an Australian Supermarket Chain, 2017–2018
Objectives. To examine the prevalence and magnitude of price promotions in a major Australian supermarket and how they differ between core (healthy) and discretionary (less healthy) food categories. Methods. Weekly online price data (regular retail price, discount price, and promotion type) on 1579 foods were collected for 1 year (April 2017 to April 2018) from the largest Australian supermarket chain. Products audited were classified according t…
