COVID-19-related lockdowns and changes in overweight and obesity, movement behaviours, diet quality, and health-related quality of life among regional Australian primary school children: A repeat cross-sectional study.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, the Australian state of Victoria (in particular, its capital, Melbourne) experienced some of the longest lockdowns in the world.

Objective: This repeated cross-sectional study examined changes between March to June 2019 (pre-pandemic) and April to August 2022 (6 to 11 months following pandemic-related lockdowns) in overweight and obesity prevalence, physical activity, sedentary behaviour, sleep, diet quality, and health-related quality of life (HRQoL) among primary school children in north-east Victoria, Australia.

Methods: Height and weight were measured for Grade 2, 4, and 6 students in 2019 (3889 children) and 2022 (1816 children).

Umbrella review of systematic reviews to inform the development and translation of community-based childhood obesity prevention interventions.

Community-based interventions (CBIs) can be effective and feasible for the prevention of childhood obesity. The aim of this umbrella review is to determine if systematic reviews report sufficient information to guide replication or adaptation of CBIs to a variety of contexts and aid in further development of childhood obesity prevention CBIs. Six databases were searched for systematic reviews including obesity prevention CBIs involving 0-18 year olds and reporting weight-related outcomes.

Three-year behavioural, health-related quality of life, and body mass index outcomes from the RESPOND randomized trial.

Objectives: Evaluate RESPOND, a community-based systems intervention to prevent childhood obesity and non-communicable diseases (NCD).

Study Design: Cluster randomized trial of building community capacity to use systems science for child obesity and NCD prevention in 10 local government areas in northeast Victoria, Australia. Four-year stepped wedge trial, adapted due to COVID-19 restrictions METHODS: Cluster randomized trial of building community capacity to use systems science for child obesity and NCD prevention in 10 local government areas in northeast Victoria, Australia.

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 at four time points (2008, 2012, 2014 and 2016) across 31 LGA.
