Bayesian Multilevel Compositional Data Analysis with the R Package <i>multilevelcoda</i> Open
Multilevel compositional data, such as data sampled over time that are non-negative and sum to a constant value, are common in various fields. However, there is currently no software specifically built to model compositional data in a mult…

<b>‘</b> Small Steps’ towards improving 24-hour time-use behaviours to decrease the risk of dementia: protocol for a personalised, web-based randomised controlled trial in community-dwelling older adults Open
Introduction Addressing physical inactivity is a promising dementia risk reduction strategy due to its direct benefits for brain health, and indirect benefits for other modifiable dementia risk factors. A potential limitation of previous i…

VRCycle: the clinical translation of a virtual reality cycling program to enhance exercise engagement in people with knee osteoarthritis Open
High-quality evidence supports exercise as a core treatment for knee osteoarthritis, improving osteoarthritis symptoms and overall health. However, most people with knee osteoarthritis are inactive and report barriers to exercise engagemen…

Exploring the role of diet quality and adiposity in the pain experience: a mediation analysis Open
Purpose Improving diet quality may lower chronic musculoskeletal pain (CMP) directly or through weight loss. This study examined whether a dietary intervention for weight-loss improved diet quality and CMP in adults with elevated adiposity…

An interactive tool to personalise 24-hour activity, sitting and sleep prescription for optimal health outcomes Open
Personalised interventions which optimise the balance of physical activity (PA), sleep and sedentary behaviour (i.e., time use) in the 24-hr day may be more effective than one-size-fits-all approaches. We present an interactive app to pers…

When the outcome is compositional - a method for conducting compositional response linear mixed models for physical activity, sedentary behaviour and sleep research Open
Time use is compositional in nature because time spent in sleep, sedentary behaviour and physical activity will always sum to 24 h/day meaning any increase in one behaviour will necessarily displace time spent in another behaviour(s). Give…

Methods for Characterization of Day-to-Day Intra-Individual Variation in 24-Hour Physical Behaviors Open
OCCUPATIONAL APPLICATIONSWe present methods to characterize individual day-to-day variation in physical behaviors, either by assessing variation in one behavior in isolation or multiple behaviors simultaneously. These methods could be used…

The Relationship Between Dietary Patterns, Cognition, and Cardiometabolic Health in Healthy, Older Adults Open
Background: Healthy dietary patterns can support the maintenance of cognition and brain health in older age and are negatively associated with cardiometabolic risk. Cardiometabolic risk factors are similarly important for cognition and may…

Should We Work Smarter or Harder for Our Health? A Comparison of Intensity and Domain-Based Time-Use Compositions and Their Associations With Cognitive and Cardiometabolic Health Open
Background Each day is made up of a composition of “time-use behaviors.” These can be classified by their intensity (eg, light or moderate–vigorous physical activity [PA]) or domain (eg, chores, socializing). Intensity-based time-use behav…

Better diet quality is associated with reduced body pain in adults regardless of adiposity: Findings from the Whyalla Intergenerational Study of Health Open
Dietary intake has been associated with pain and physical function, but it is unclear if these relationships are mediated by adiposity. Data were derived from the Whyalla Intergenerational Study of Health (n = 654, 57% women). Structural e…

Measuring 24‐h use of time in people with a diabetes‐related foot ulcer: A feasibility study Open
Background Physical activity (PA), sleep and sedentary time are now recognised as mutually exclusive and exhaustive parts of the 24‐h day—if PA decreases, time spent sleeping, being sedentary or both must increase so that all components eq…

Cross-sectional associations between 24-hour time-use composition, grey matter volume and cognitive function in healthy older adults Open
Background Increasing physical activity (PA) is an effective strategy to slow reductions in cortical volume and maintain cognitive function in older adulthood. However, PA does not exist in isolation, but coexists with sleep and sedentary …
