“…While these studies provide some support for our ndings it is important to recognise that total ST as reported in our compositional analysis is a different measure than screen time, screen time can occur in non-sedentary postures (74), and high ST is largely independent of screen time (75). It is unclear whether total ST (25) or speci c types of ST are more strongly related to mental health outcomes (76). To address this, future studies should employ methodologies such as ecological momentary assessment or device-based pattern recognition approaches to identify speci c types of sedentary behaviours (76), which may provide a more precise picture of the compositional relationships between activity behaviours and mental health.…”

Background. The prevalence of mental ill health increases with age through childhood and adolescence and likely impairs mental and physical health in adulthood. Little is known about the combined influence of sleep, sedentary time (ST), and physical activity on youth mental health. This study examined associations between youth 24-hour activity behaviour compositions and mental health indicators, and investigated predicted differences in mental health when time was reallocated between activity behaviours.Methods. Demographic information and anthropometric data were collected from 359 participants (aged 9-13 years; 50.7% girls). 24-hour activity behaviours (sleep, ST, light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA)) were assessed using a wrist accelerometer, worn for 7 days. Validated questionnaires measured self-esteem, depressive symptomology, overall emotional and behavioural mental health, internalising problems, externalising problems, and prosocial behaviour. A computerised cognitive test battery assessed executive functions of switching, spatial working memory, and inhibition. Linear mixed models examined associations between activity behaviour compositions and mental health indicators for all participants and separately by primary and secondary school. Post-hoc analyses modelled the influence of reallocating fixed durations of time between activity behaviours on mental health.Results. For all participants ST was associated with worse internalising problems, relative to the other activity behaviours. Among primary school participants, relative to the other activity behaviours, ST was associated with poorer prosocial behaviour, and LPA was associated with worse switching and inhibition test scores. For all participants, reallocating time to ST from sleep and MVPA was associated with higher internalising problems. Among primary school participants, reallocating time to ST from any other behaviour was associated with poorer prosocial behaviour, and reallocating time to LPA from any other behaviour was associated with lower cognitive function.Conclusions. Relative to other activity behaviours, ST and LPA were significantly and unfavourably associated with some mental health indicators. These associations were strongest among primary school participants with no significant relationships observed for the secondary school participants. Replacing MVPA with ST or LPA reflected the greatest unfavourable predicted changes in mental health indicators. Our results provide further evidence for the influence of daily activity behaviours on youth mental health.

“…Neither light physical activity nor the modality or contextual factors associated with physical activity were included, both of which have implications for mental health. 55 Light activity is likely one movement behaviour that signi cant time is allocated to each day. Finally, this study was cross-sectional so the direction of effects cannot be discerned.…”

Background: Physical activity, sedentary behavior, and sleep are associated with mental health in adolescents. Mental health may depend not only on the amount of time spent in a specific activity, but also on the activity it displaces. The aim of this study was to examine the impact of reallocating 15 minutes of time spent in one health behavior with 15 minutes in another on adolescent mental health. Methods: Cross-sectional data from the students participating in the COMPASS Study (2018-2019) were analyzed (N = 46,413). Participants self-reported the amount of time they spent engaged in moderate-to-vigorous physical activity (MVPA), doing homework and using screens, and their sleep duration on average each day. Participants also self-reported depressive symptoms, anxiety, and flourishing. Data were analyzed using isotemporal substitution modeling. Results: Non-linear associations were evident between sleep and the mental health outcomes, so analyses were stratified by sleep duration based on whether students reported meeting current guidelines or not. Among adolescents getting less than the recommended amount of sleep, replacing any behaviour with sleep was generally associated with better mental health outcomes. Conversely, among adolescents getting adequate sleep, the findings did not support replacing other behaviors with sleep with the exception of screen time. Replacing homework and MVPA with sleep was associated with less flourishing regardless of sleep duration. Of the two sedentary behaviors assessed, replacing screen time with homework was associated with less depression and greater flourishing. However, replacing any behavior with homework was associated with greater anxiety regardless of whether participants reported adequate sleep or not.Conclusions: Replacing screen time with any behaviour may be better for mental health outcomes. Results provide further support for the critical role of sleep in promoting healthy development during adolescence, though more sleep than is recommended may confer little benefit for mental health. Youth getting adequate sleep may benefit from replacing screen time with homework or MVPA. The findings demonstrate that mental health benefits may be obtainable at intervals as short as 15 minutes.

“…The Second Edition of the Physical Activity Guidelines for Americans published in 2018, note that any amount of physical activity has some health benefits, and removed the recommendation that only 10-min bouts of physical activity counted towards meeting the guidelines [27]. Finally, while the IPAQ assesses total levels of physical activity, it does not differentiate between activities performed for the purposes of structured exercise and physical activities performed as part of daily life, which may also have important implications for mental health outcomes [28].…”

Background: Physical inactivity is a key contributor to the global burden of disease and disproportionately impacts the wellbeing of people experiencing mental illness. Increases in physical activity are associated with improvements in symptoms of mental illness and reduction in cardiometabolic risk. Reliable and valid clinical tools that assess physical activity would improve evaluation of intervention studies that aim to increase physical activity and reduce sedentary behaviour in people living with mental illness. Methods: The five-item Simple Physical Activity Questionnaire (SIMPAQ) was developed by a multidisciplinary, international working group as a clinical tool to assess physical activity and sedentary behaviour in people living with mental illness. Patients with a DSM or ICD mental illness diagnoses were recruited and completed the SIMPAQ on two occasions, one week apart. Participants wore an Actigraph accelerometer and completed brief cognitive and clinical assessments. Results: Evidence of SIMPAQ validity was assessed against accelerometer-derived measures of physical activity. Data were obtained from 1010 participants. The SIMPAQ had good test-retest reliability. Correlations for moderatevigorous physical activity was comparable to studies conducted in general population samples. Evidence of validity for the sedentary behaviour item was poor. An alternative method to calculate sedentary behaviour had stronger evidence of validity. This alternative method is recommended for use in future studies employing the SIMPAQ. Conclusions: The SIMPAQ is a brief measure of physical activity and sedentary behaviour that can be reliably and validly administered by health professionals.
