Association of Accelerometer-Derived Physical Activity Pattern With the Risks of All-Cause, Cardiovascular Disease,...

Area of Science:

• Public Health
• Epidemiology
• Exercise Science

Background:

• Current health guidelines recommend 150 minutes of weekly moderate to vigorous physical activity (MVPA).
• The impact of concentrated versus evenly distributed physical activity (PA) on health outcomes is not well understood.
• This study examines the

Purpose of the Study:

• To investigate the association between the

Main Methods:

• Utilized UK Biobank data from 2013-2015 with device-measured PA.
• Classified participants into inactive, active weekend warrior, and active regular MVPA patterns.
• Employed Cox proportional hazards models to analyze PA patterns and mortality risk.

Main Results:

• Over 8.1 years, both active weekend warrior and active regular groups showed reduced all-cause, cardiovascular disease, and cancer mortality compared to inactive individuals.
• Hazard ratios for all-cause mortality were 0.68 (95% CI, 0.64-0.74) for weekend warriors and 0.74 (95% CI, 0.68-0.81) for regular exercisers.
• No significant difference in mortality risk was observed between the active weekend warrior and active regular groups.

Conclusions:

• Concentrating physical activity (PA) into 1-2 days per week is associated with similar mortality risk reduction as evenly distributed activity.
• Findings are especially relevant for individuals facing time constraints for regular exercise.
• Meeting weekly MVPA recommendations, regardless of distribution, is linked to significant health benefits.
