Approved Research

Optimal daily time-use composition for different non-communicable diseases

Principal Investigator: Dr Philip von Rosen
Approved Research ID: 72057
Approval date: October 5th 2021

Lay summary


The purpose of this project is to explore the optimal daily time-use composition of sleep, sedentary behaviour (SB) and physical activity (PA) for different non-communicable diseases (NCDs) such as Stroke, Myocaridal infarction, Chronic obstructive pulmonary disease, Parkinsons disease, Breast cancer, Prostate cancer, Colorectal cancer, Dementia, Type 2 diabetes. This study will also identify different health profiles and how they contribute to different NCDs.

Scientific rationale

PA and sleep are protective factors and sedentary behaviour is a risk factor for NCDs. A few studies have also highlighted that too short or too long sleep duration may increase the risk of adverse health outcomes. How the joint association of these behaviours contribute to the risk of NCDs are largely unknown. In addition, previous research has used self-report data for different behaviours and not considered that time spent in sleep, SB and PA represent relative information of the complete day.

Project duration

This project will last for 36 months and aims to improve our understanding of how people can spend time in sleep, SB and PA to reduce the risk for different NCDs.

Public health impact

The result of this project will provide evidence to underpin robust integrated public health guidelines about sleep, SB and PA for optimal health. Clear guidelines are important as time spent in different behaviours are modifiable and could be target on different society levels and with many different approaches. Therefore, this study will add an important piece to the research field by demonstrating the effect of the joint associations between sleep, SB and PA and several NCDs.
