About

Dr. Tarun Katapally is a physician and a population health researcher. After obtaining clinical experience in India and the United Kingdom, Dr. Katapally went on to diversify his career towards health administration and population health. Apart from his clinical degree, he has a Master’s degree in health administration from Saint Joseph’s University, Philadelphia and a PhD in population health science from the college of medicine at the University of Saskatchewan. Dr. Katapally brings a global perspective to policy research by combining his clinical experience with interdisciplinary epidemiological methods. His research network spans across diverse institutions both within and outside Canada.

He established the Digital Epidemiology and Population Health (DEPtH) Laboratory in 2017, which implements the SMART Platform developed by him by combining the concepts of citizen science, community-based participatory research, and systems science. Currently, he holds an adjunct faculty position in the college of medicine at the University of Saskatchewan and is a Patient-Oriented Research Leader. He is also the country leader for India for the development of global report cards on the physical activity for children and youth. He has co-founded Active Healthy Kids India, which promotes active living policy in the second-most populous nation in the world. Dr. Katapally’s expertise is in linking advanced mixed-methods and complex analytical techniques with community-based participatory research to understand the impact of policy and policy-driven contexts and systems on health and wellbeing of populations. Increasingly, his focus is on the usage of digital epidemiological tools in informing policy through integrated knowledge translation to promote the health of vulnerable populations such as Indigenous youth.

Dr. Katapally's DEPtH Laboratory is currenlty seeking competitive applications for masters, doctoral and post-doctoral degrees from candidates interested in conducting cutting-edge active living research using ubiquitous tools such as smartphones. Click here for more information.

Current Research

  • SMART Adults - SMART Adults was the foundational pilot that provided vital evidence to scale up the SMART Platform. In 2017 and 2018, we engaged with adult citizen scientists across the life course to test various aspect of the Platform, from recruitment strategies to survey protocols and compliance measures to ecological momentary assessments. More importantly, we developed a deep understanding of evidence-based approaches that apply to various adult cohorts (18-35; 36-65; >65) in terms of recruitment, retention, continuous engagement, data management, and ethical implications, which are critical factors for the success of mobile health innovations. For instance, effective recruitment and retention of older cohorts (>65 years) requires continuous engagement and in-person deployment of mobile applications to minimize social isolation and potential technology-related anxiety. Irrespective of the age cohort, we learned that the ultimate success of any mobile health program depended on integrating citizen science with community-based participatory research and ensuring data security and confidentiality. Based on the evidence generated from previous cycles, in 2019, we are gearing up to engage adult citizen scientists with a particular focus on involving them in influencing health policies. 
  • SMART Response SMART Response is the most advanced edition of the SMART Platform and it's purpose it to develop real-time interventions to address population health crises. SMART Response is working with communities, citizen scientists, and stakeholders to identify, address, and evaluate real-time interventions. By involving citizen scientists as equal partners, SMART Response is developing smartphone apps that are aimed to improve holistic health. As the strength of SMART Response is to adapt to the changing community needs and stakeholder priorities, it is being developed as a versatile platform that could be adapted for rapid response.
  • SMART Indigenous Youth - Utilizing the SMART Platform, this 5-year community trial is being conducted in 4 communities (2-rural and 2-remote) in Saskatchewan. The trial involves the embedding of a culturally, linguistically, and geographically appropriate land-based active living intervention into the school curricula in collaboration with on-reserve school administrators, Elders, and community leaders. The youth are the citizen scientists in this initiative, where they interact with researchers in real-time using smartphones to provide their perception of their evolving behaviours in concert with the intervention being implemented. The focus of the intervention will be on holistic wellness, including physical, mental, emotional, and spiritual health. Knowledge Translation, Citizen Engagement, and Community Participation are the three pillars of this trial.  Community partners are not only consulted continuously, but also co-own the data, determine changes to the intervention, and collaborate in knowledge dissemination.
  • SMART India - SMART India utilizes the SMART Platform to leverage innovative, smartphone-based methods to collect physical activity and complex contextual data by engaging with Indian children and youth in India. The initial phase of this study focuses exclusively on children and youth, and the data obtained will fill critical evidence gaps on various indicators of active living as identified by the 2016 and 3018 India Report Cards on Physical Activity for Children and Youth. Moreover, these data will be compared with Canadian data collected using the same methods to inform cross-country policies.
  • SMART YouthSMART Youth extend the SMART Platform to schools in Saskatchewan, where we work closely with the school boards and individual schools in giving youth and educators the opportunity to become citizen scientists. As part of this initiative, we hope to co-create knowledge with schools, where youth share their perceptions of school environment, as well as behavioural data. Educators would be invited to provide policy and programming data. This initiative will allow youth and educators to use a free smartphone application in different seasons in Saskatchewan to engage with researchers from the University of Regina and Saskatchewan.
  • Addressing Access Differences in Healthcare Between Status Indians and Other Canadians - This initiative is to inform policy solutions through the quasi-experimental evaluation of natural policy experiments as part of the bifurcated health care system in Canada. The goal is to address inequities in access to extended health benefits to a legally defined sub-group of Indigenous Canadians registered by the federal government as “status Indians.” This study is based on a pilot conducted by the principal applicants (Greg Marchildon and Tarun Katapally) in Saskatchewan that revealed difficulties in access to diagnostic and treatment services for obstructive sleep apnea among status Indians. This difficulty in access, which manifests in longer wait times, is an example of a health inequity that exacerbates lower health status and poorer health outcomes in Indigenous populations across Canada and other settler nations.
  • Impact of Childcare Policies and Programs on Early Years Children's Physical Activity: A natural experiment - This is a prospective community trial that investigates the effect of different policy, program, and physical environment settings across the four childcare settings in Regina on active play among early years children (2-5 years). In essence, it will be a natural experiment to inform future policies and programs by evaluating the impact of existing settings.
  • Informing Upstream Evidence-based Policies to Minimize Screen Time Amount Youth: A compass sub-study - This project uses data from the COMPASS Study’s prospective quasi-experimental platform to evaluate the influence of school policies and programs on youth behaviour across Alberta, Ontario, and Quebec (https://uwaterloo.ca/compass-system/compass-system-projects/compass-study). The project is divided into two phases: 1. Informing school policies by understanding the influence of school physical activity policies and programs on multiple screen time behaviours among youth. 2. Informing school policies by understanding the influence of school bullying policies and perception of school connectedness on multiples screen time behaviours among youth. The multiple types of screen time include: television viewing, video gaming, Internet usage, and texting.
  • Global Matrix 3.0: Cross-country Knowledge Translation - Global Matrix 3.0 is the next installment (2018) of the twice-yearly international initiatives that Active Healthy Kids Global Alliance conducts. In 2016, Global Matrix 2.0 evaluated various aspects of child and youth active living in 38 countries spread across six continents (https://www.activehealthykids.org/). Global Matrix 3.0 is scaling up the project to include 52 countries. As part of this initiative, country-specific teams are developing Report Cards by appraising current evidence using rigorous methods and by assigning standardized grades to previously developed indicators of active living. The Report Cards summarizes current evidence on not only key contexts such as family and peers, schools, and neighbourhood environment, but also the government strategies, policies, and investments that impact these contexts. The Report Cards will be unveiled in December 2018 in Aldelaide, Australia.
  • Assess, Redress, Re-assess: Addressing disparities in respiratory health among First Nations Youth - This is a complex multi-year community-based participatory research initiative involving two On-Reserves First Nations communities in central Saskatchewan. Implemented in four phases (baseline assessment, policy interventions [redress], community interventions [address] and evaluation), this population health intervention study targets four key determinant-outcome dyads identified by the communities. As part of this project, Dr. Katapally leads the physical activity, sedentary behaviour, and obesity study, as well as the obstructive sleep apnea-related study.
  • Seasonality and Acitive Saskatoon Kids - Seasonality and Active Saskatoon Kids is an active living initiative that investigates children's physical activity and sedentary behaviour patterns longitudinally. This study utilizes GPS-equipped accelerometers to determine how children interact with urban spaces in all seasons to identify indicators of active living. This knowledge will inform urban planning policy in Saskatoon to help develop active urban communities.

Knowledge Translation

  • Innovation and technology transfer: Smartphone app for active living. Role: Innovator. Target Stakeholders: General public and health care personnel. Outcome/Deliverable: A smartphone application that aids in increasing physical activity and decreasing sedentary behaviour. Evidence of Impact: Selected for the 2014 University of Saskatchewan Tech Venture Challenge.
  • Patient-oriented obstructive sleep apnea care policy intervention in Aboriginal Peoples. Role: Researcher (IPHRC). Target Stakeholders: Policy makers, health care personnel and patients. Outcome/Deliverables: A three-tiered knowledge translation strategy (patients, physicians and policy makers) to introduce practice and policy change with respect to inequities in access to health services for obstructive sleep apnea care in Aboriginal Peoples. Evidence of Impact: Identified areas of improvement in sleep apnea care provision.
  • Integrated knowledge translation through community-based participatory research. Role: Researcher (IPHRC). Target Stakeholders: Elders and community leaders. Outcome/Deliverables: A community-based participatory intervention, where at every phase of the intervention, the communities participate in knowledge generation and dissemination. Evidence of Impact: Adaptation of ongoing interventions based on integration of Indigenous Knowledge.
  • 2016 India Report Card on the Physical Activity of Children and Youth. Role: Report card leader. Target Stakeholders: Policymakers, parents, educators, researchers, public health administrators, and the general public. Outcome/Deliverables: Synthesis and translation of current evidence on the policies and contexts that influence physical activity in children in India. Evidence of Impact: Already enabled cross-country comparison between low, middle and high-income countries. Predicted impact in the near future would be to inform policies and raise awareness of the dearth of evidence in middle income countries.
