Strengthening Culturally Responsive Mental Health Supports for Crises Preparedness
BACKGROUND: The COVID-19 pandemic intensified existing systemic inequities in educator mental health, particularly in rural and remote Indigenous communities. Educators faced sudden shifts to remote learning, limited access to technology, and challenges supporting students' well-being while adapting pedagogical practices. METHODS: This qualitative longitudinal, citizen science study explored culturally grounded digital engagement tools to support…
The Association Between Recreational Cannabis Use and 24‐hour Movement Behaviours
INTRODUCTION: The prevalence of cannabis use among youth is rising globally, making it crucial to understand its role in health and well-being. While cannabis use is linked to various health outcomes, evidence on its relationship with 24-h movement behaviours (moderate-to-vigorous physical activity, sedentary behaviour, and sleep) in youth is limited. This study uses a digital citizen science approach to examine these associations among Canadian …
Towards ethical surveillance of smartphone use among youth
A potential environmental paradox in India
DiScO
Background: Global health systems are confronting challenges that intersect climate change with evolving communicable and non-communicable public health risks. Addressing these challenges requires systems integration via citizen big data that exist outside health systems. However, systems integration across jurisdictions is a complex challenge that requires stakeholder input. This study's purpose was to conduct rapid systems mapping with internat…
Inverting social innovation to transform health system responses to climate change adaptation and mitigation in the global south
Systems thinking is aimed at understanding and solving complex problems that cut across sectors, an approach that requires accurate, timely, and multisectoral data. Citizen-driven big data can advance systems thinking, considering the widespread use of digital devices. Using digital platforms, data from these devices can transform health systems to predict and prevent global health crises and respond rapidly to emerging crises by providing citize…
Prevalence and factors associated with sarcopenia among urban and rural Indian adults in middle age
Sarcopenia is the age-related loss of muscle mass and function. India has 8.6% of the global elderly (>60 years) population, and this is expected to increase to 20% by 2050. Around 70% of Indians live in rural areas where lifestyle factors like diet and physical activity differ from urban areas. Understanding age, sex and location-specific sarcopenia prevalence in India is crucial. Thus, our aim was to assess the prevalence and determinants of sa…
Social Experiences, Social Support and Residence as Determinants of Sedentary Behaviour Among Indigenous Adults in Saskatchewan
Centuries of ongoing colonization, assimilation and historic trauma have changed social structures, roles and responsibilities among Indigenous Peoples: First Nations, Métis and Inuit. Social factors and experiences can influence sedentary behaviour; however, relationships between social determinants and sedentary behaviour among Indigenous Peoples in Saskatchewan are unclear. Objective: The purpose of this study is to examine historic trauma, so…
Influence of parental anthropometry and gestational weight gain on intrauterine growth and neonatal outcomes
Poor foetal growth and subsequent low birth weight are associated with an increased risk for disease later in life. Identifying parental factors that determine foetal growth are important to curbing intergenerational malnutrition, especially among disadvantaged populations in the global south where undernutrition rates are high. The objective of this study was to assess the relationships between parental biometry, intrauterine growth and neonatal…
Is excessive smartphone use associated with weight status and self-rated health among youth? A smart platform study
The results indicate that excessive screen time on smartphones does have complex associations with youth health. Further investigation with more robust study designs is needed to inform smartphone-specific screen time guidelines for youth
The interplay between air pollution, built environment, and physical activity
Global Matrix 4.0 Physical Activity Report Card Grades for Children and Adolescents
Background : The Global Matrix 4.0 on physical activity (PA) for children and adolescents was developed to achieve a comprehensive understanding of the global variation in children’s and adolescents’ (5–17 y) PA, related measures, and key sources of influence. The objectives of this article were (1) to summarize the findings from the Global Matrix 4.0 Report Cards, (2) to compare indicators across countries, and (3) to explore trends related to t…
Methodology to Derive Objective Screen-State from Smartphones
Time on screens (screen time) on multiple digital devices (computers, mobile phones, tablets, television screens, etc.) due to varied motivations (work, leisure, entertainment, gaming, etc.) has become an integral part of population behaviour. However, a significant evidence gap exists in screen time accumulated over ubiquitous mobile devices such as smartphones. This study aimed to develop an accurate, reliable and replicable methodology to deri…
Global Matrix 3.0 Physical Activity Report Card Grades for Children and Youth
Background : Accumulating sufficient moderate to vigorous physical activity is recognized as a key determinant of physical, physiological, developmental, mental, cognitive, and social health among children and youth (aged 5–17 y). The Global Matrix 3.0 of Report Card grades on physical activity was developed to achieve a better understanding of the global variation in child and youth physical activity and associated supports. Methods : Work group…
Racial discrimination and depression among on-reserve First Nations people in rural Saskatchewan
A methodology to leverage cross-sectional accelerometry to capture weather’s influence in active living research
Capturing the Interrelationship between Objectively Measured Physical Activity and Sedentary Behaviour in Children in the Context of Diverse Environmental Exposures
Even though physical activity and sedentary behaviour are two distinct behaviours, their interdependent relationship needs to be studied in the same environment. This study examines the influence of urban design, neighbourhood built and social environment, and household and individual factors on the interdependent relationship between objectively measured physical activity and sedentary behaviour in children in the Canadian city of Saskatoon. Sas…
Exploring policy driven systemic inequities leading to differential access to care among Indigenous populations with obstructive sleep apnea in Canada
In order to confirm initial findings, further investigations are required in other Canadian jurisdictions. Moreover, as other clinical conditions could share similar features of health care access and provision of health benefits coverage, this policy analysis could be replicated in other provincial and territorial health care systems across Canada, and other settler nations where there are differential health coverage arrangements for Indigenous…
Longitudinal active living research to address physical inactivity and sedentary behaviour in children in transition from preadolescence to adolescence
This approach will help us understand the influence of urban environment on children's activity, thus paving the way to modify urban spaces to increase physical activity and decrease sedentary behaviour in children in all four seasons. Lack of physical activity and rising sedentariness is associated with rising childhood obesity, and childhood obesity in turn is linked to many chronic conditions over the life course. Understanding the interaction…
Validation of Standardization Methodology to Minimize Measurement Bias Due to Systematic Accelerometer Wear-Time Variation in Preschoolers, Adolescents, and Adults
Introduction Increasingly, physical activity (PA) and sedentary behaviour (SED) are independently being associated with physical, mental and emotional well-being. The heightened research interest in this area has resulted in an upsurge of accelerometer usage to objectively quantify PA and SED. However, these epidemiological investigations consistently ignore systematic variation in the number of hours participants wear accelerometers each day (i.…
