    • Associations between Traffic-Related Air Pollution and Cognitive Function in Australian Urban Settings: The Moderating Role of Diabetes Status 

      Tham, Rachel; Wheeler, Amanda J.; Carver, Alison; Dunstan, David; Donaire-Gonzalez, David; Anstey, Kaarin J.; Shaw, Jonathan E.; Magliano, Dianna J.; Martino, Erika; Barnett, Anthony; Cerin, Ester (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-27)
      Traffic-related air pollution (TRAP) is associated with lower cognitive function and diabetes in older adults, but little is known about whether diabetes status moderates the impact of TRAP on older adult cognitive function. We analysed cross-sectional data from 4141 adults who participated in the Australian Diabetes, Obesity and Lifestyle (AusDiab) study in 2011–2012. TRAP exposure was estimated ...

    • From urban neighbourhood environments to cognitive health: a cross-sectional analysis of the role of physical activity and sedentary behaviours 

      Cerin, Ester; Barnett, Anthony; Shaw, Jonathan E.; Martino, Erika; Knibbs, Luke D.; Tham, Rachel; Wheeler, Amanda J.; Anstey, Kaarin (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-23)
      <p><b>Background: </b> There is a dearth of studies on the effects of the neighbourhood environment on adults’ cognitive function. We examined how interrelated aspects of the built and natural neighbourhood environment, including air pollution, correlate with adults’ cognitive function, and the roles of physical activity and sedentary behaviours in these associations. <p><b>Methods:</b> We used ...

    • Improving traffic-related air pollution estimates by modelling minor road traffic volumes 

      Alvarado-Molina, Miguel; Curto, Ariadna; Wheeler, Amanda J.; Tham, Rachel; Cerin, Ester; Nieuwenhuijsen, Mark; Vermeulen, Roel; Donaire-Gonzalez, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-07)
      Accurately estimating annual average daily traffic (AADT) on minor roads is essential for assessing traffic-related air pollution (TRAP) exposure, particularly in areas where most people live. Our study assessed the direct and indirect external validity of three methods used to estimate AADT on minor roads in Melbourne, Australia. We estimated the minor road AADT using a fixed-value approach ...

    • Urban Neighbourhood Environments, Cardiometabolic Health and Cognitive Function: A National Cross-Sectional Study of Middle-Aged and Older Adults in Australia 

      Cerin, Ester; Barnett, Anthony; Shaw, Jonathan E.; Martino, Erika; Knibbs, Luke D.; Tham, Rachel; Wheeler, Amanda J.; Anstey, Kaarin J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-07)
      Population ageing and urbanisation are global phenomena that call for an understanding of the impacts of features of the urban environment on older adults’ cognitive function. Because neighbourhood characteristics that can potentially have opposite effects on cognitive function are interdependent, they need to be considered in conjunction. Using data from an Australian national sample of 4141 adult ...
