Personal Activity Intelligence (PAI), Sedentary Behavior and Cardiovascular Risk Factor Clustering - the HUNT Study

Area of Science:

• Cardiology
• Public Health
• Preventive Medicine

Background:

• Prolonged sedentary behavior (SB) is linked to increased cardiovascular disease (CVD) risk factor clustering.
• Personal Activity Intelligence (PAI) is a metric assessing physical activity (PA) based on heart rate, age, and sex.
• A weekly PAI score of ≥100 is associated with reduced CVD mortality risk.

Purpose of the Study:

• To investigate whether PAI modifies the association between SB and clustering of CVD risk factors (CV-RF).
• To analyze this relationship in a large cohort of apparently healthy adults.

Main Methods:

• A large general population cohort (n=29,950, aged ≥20 years) was studied.
• Logistic regression analysis was employed to assess the associations.
• The study examined the impact of weekly PAI levels on CV-RF clustering in relation to SB.

Main Results:

• In individuals achieving ≥100 weekly PAI, the association between prolonged SB and CV-RF clustering was attenuated across all age groups.
• This protective effect of PAI was observed regardless of meeting general PA recommendations.

Conclusions:

• Maintaining a weekly PAI of ≥100 may mitigate the adverse effects of sedentary behavior on cardiovascular health.
• Monitoring PAI levels could be a valuable strategy to encourage sufficient physical activity and counteract risks associated with sedentary lifestyles.
