Measuring 24-h use of time in people with a diabetes-related foot ulcer: A feasibility study.

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 equate to 24 h. Recent advances in time-use epidemiology suggest that we should not consider time-use domains (PA, sleep and sedentary time) in isolation from each other, but in terms of a composition-the mix of time-use domains across the 24-h day. While interrelated daily activities are known to be important in the management of diabetes mellitus, few studies have investigated the interrelated daily activities in people with an active diabetes-related foot ulcer (DFU) and their impact on important outcomes such as wound severity, blood glucose control and health-related quality of life (HRQoL).

Children's activity and diet behaviours in the summer holidays versus school year.

Background: Evidence shows children gain more weight during the summer holidays versus the school year.

Objectives: To examine within-child differences in activity and diet behaviours during the summer holidays versus the school year.

Methods: Children (mean age 9.

Parent wellbeing, family screen time and socioeconomic status during early childhood predict physical activity of Aboriginal and Torres Strait Islander children at ages 8-13.

Objectives: Physical activity is holistically linked to culture and wellbeing among Aboriginal and Torres Strait Islander peoples, the First Nation Peoples of Australia. Socioecological correlates of high physical activity among Indigenous children include living in a remote area and low screen time but little is known about early life determinants of physical activity. This paper examines sociodemographic, family, community, cultural, parent social and emotional wellbeing determinants of physical activity among Aboriginal and Torres Strait Islander children.

Joint Profiles of Sedentary Time and Physical Activity in Adults and Their Associations with Cardiometabolic Health.

Purpose: This study aimed to identify and characterize joint profiles of sedentary time and physical activity among adults and to investigate how these profiles are associated with markers of cardiometabolic health.

Methods: The participants included 3702 of the Northern Finland Birth Cohort 1966 at age 46 yr, who wore a hip-worn accelerometer during waking hours and provided seven consecutive days of valid data. Sedentary time, light-intensity physical activity, and moderate- to vigorous-intensity physical activity on each valid day were obtained, and a data-driven clustering approach ("KmL3D") was used to characterize distinct joint profiles of sedentary time and physical activity intensities.

Are all MVPA minutes equal? Associations between MVPA characteristics, independent of duration, and childhood adiposity.

Background: The inverse relationship between moderate-to-vigorous physical activity (MVPA) duration and childhood adiposity is well established. Less is known about how characteristics of MVPA accumulation may be associated with adiposity, independent of MVPA duration. This study aimed to investigate how the MVPA characteristics of children, other than duration (bout length, time of day, day-to-day consistency, intensity), were associated with adiposity.

Does home equipment contribute to socioeconomic gradients in Australian children's physical activity, sedentary time and screen time?

Background: Activity behaviours (physical activity, sedentary time and screen time) have been linked to health outcomes in childhood. Furthermore, socioeconomic disparities have been observed in both children's activity behaviours and health outcomes. Children's physical home environments may play a role in these relationships.

The associations between physical activity, sedentary behaviour and academic performance.

Objectives: To examine the relationships between children's moderate-to-vigorous physical activity (MVPA), sedentary behaviours, and academic performance.

Design: This study investigated cross-sectional relationships between children's accelerometer-measured physical activity and sedentary behaviour patterns, and academic performance using a standardised, nationally-administered academic assessment.

Methods: A total of 285 Australian children aged 9-11 years from randomly selected schools undertook 7-day 24h accelerometry to objectively determine their MVPA and sedentary behaviour.
