The Nordic Seminar on Technical Measurements of Physical Activity and Sedentary Behaviour is an arena for sharing knowledge, fostering collaboration, and exchanging ideas among the Nordic community engaged in research on technical measurements of physical activity and sedentary behaviour. Previous seminars have been organised in Copenhagen and Gothenburg. This is the 5th annual meeting and will be organized by NTNU in Trondheim. The seminar has a multidisciplinary profile and encompass participants from several disciplines including clinical science, computer science, engineering, physiology, public health, and epidemiology.

Program

The seminar is organised over two days (June 2nd – 3rd, 2022) as a joint effort between Department of Public Health and Nursing, NTNU and Department of Computer Science, NTNU. This is an in-person event and we do not plan to record or stream the presentations.

Day 1 (Location: KA12, Kunnskapssenteret)

Session 1 will focus on recent advancements in measurements and analysis. The presentations are followed by a plenary session with questions and discussion. This session is important to facilitate discussions about methodological challenges within the field and to update the community on new methodological approaches.

Time Presentation
09:00 Registration and Coffee
09:30 Welcome and Introduction
Paul Jarle Mork
09:40 The 24-hr paradigm – recent advancements and the way forward
Charlotte L Rasmussen
10:10 - 10:30 Session 1: Advancements in measurements and analysis (chair: Kerstin Bach)
Nidhi Gupta: SurPASS: Automating Device-based Measurement in Cohort Study Research
10:30 - 10:50 Coffee Break
10:50 - 12:00 Daniel Arvidsson: Methodological decisions before analysing raw accelerometer data in the SCAPIS project
Jonatan Fridolfsson: From processing of raw accelerometer data to multivariate analysis
Eivind Aadland: Multivariate pattern analysis of the physical activity intensity spectrum – what have we learned?
Questions and discussion – session 1
12:00 - 13:00 Lunch Break

Session 2 will focus on the 24-hour paradigm, which is a special challenge within the field of technical measurements of physical activity and sedentary behaviour (i.e., the compositional nature of 24 hours data). Compositional data analysis (CODA) has been used in other fields such as geology and economics for several decades but is relatively new within epidemiology. We have several excellent researchers within the Nordic countries that have developed expertise within this. The purpose of this second session is to update the community on recent advancements in the application of CODA within the field of epidemiology.

Time Presentation
13:00 - 14:50 Session 2: Advancements in measurements and analysis (chair: Nidhi Gupta)
Ellen Marie Bardal: STUNTH – a new cohort on health care workers
Pia Skovdahl: Physical activity in children with congenital heart disease: when methodological improvements matter
Peter Johansson & Pasan Hettiarachchi: ActiPASS – validation of time lying down and sleep
Jasper Schipperijn: Adding context to accelerometer data using GPS devices
Questions and discussion – session 2
14:30 - 14:50 Coffee Break

Session 3 is dedicated to cohort studies, intervention studies, and reviews. Several large cohorts with technical measurements of physical activity and sedentary behaviour have been established in the Nordic countries during the last decade (e.g., HUNT4 2017-19, Tromsø7 2015-16, and SCAPIS 2014-18). These data have now been linked to registry data and other follow-up data to allow prospective studies of the association between physical activity/sedentary behaviour. The seminar provides an important avenue for presenting these results and discuss how the results can be used to inform the development of future interventions and policy.

Time Presentation
14:50 - 16:00 Session 3: Cohorts, methods, and interventions (chair: Tom Ivar Lund Nilsen)
Mats Flaaten: Applying Mendelian randomization in the HUNT Study
Atle Kongsvold: HUNT – Self-reports vs. objective measurements
Jonatan Fridolfsson: Considering individual fitness when analyzing associations between physical activity and health in the SCAPIS project
Questions and discussion – session 3

Evening Program (Location: Rockheim)

Day 1 closes with social activity (speed dating for research collaboration) and a dinner for all participants.

Time Presentation
18:00 Speed-dating for research collaboration (chairs: Anne Lovise Nordstoga and Charlotte L Rasmussen)
19:00 Dinner

Day 2 (Location: KBA, Kvinne-barn-senteret)

Session 4 is a continuation of session 3 (day 1), with a focus on cohorts, methods, and interventions. This also includes presentations on harmonisation of existing data and data collection. The latter is an important and challenging issue in health sciences, which hampers data pooling and comparison of results across studies. We aim to establish a Nordic working group to follow up on further work regarding data harmonisation. Session 5 also includes presentations on new methods for making causal inference in epidemiological research, i.e., utilisation of genetic information as instrument variables in Mendelian randomisation studies.

Time Presentation
09:00 Welcome and Coffee
