Weekend Warrior and Regular Physical Activity Patterns Are Associated With Reduced Lung Cancer Risk

TOPLINE:

Compared with inactive patterns, weekend warrior (moderate-to-vigorous physical activity [MVPA] condensed into 1-2 days per week) and regular physical activity patterns were found to be equally effective at reducing the risk for lung cancer. Neither pattern showed significant associations with the overall risk for cancer or specific risks for prostate, breast, and colorectal cancers.

METHODOLOGY:

• This analysis included 80,896 participants (mean age, 55.5 years; 56% women) with valid accelerometer data collected between June 2013 and December 2015.
• Participants were classified into three groups: 32,213 active weekend warriors (≥ 150 minutes of weekly MVPA with ≥ 50% achieved in 1-2 days), 22,162 active regular participants (≥ 150 minutes of MVPA but not meeting a weekend warrior pattern), and 26,521 inactive participants (< 150 minutes of MVPA).
• Researchers tracked associations between physical activity patterns and incident cases of all types of cancer plus specific cases of prostate, breast, colorectal, and lung cancer over a median follow-up duration of 6 years.

TAKEAWAY:

• Compared with inactive patterns, active weekend warrior patterns showed a significant inverse association with the risk for lung cancer (hazard ratio [HR], 0.77; 95% CI, 0.61-0.98).
• Active regular activity patterns demonstrated similar protective effects against lung cancer as inactive patterns (HR, 0.73; 95% CI, 0.56-0.96).
• Neither of the physical activity patterns showed any significant association with the overall risk for cancer or specific risks for prostate, breast, and colorectal cancers.

IN PRACTICE:

"Physical activity condensed into one to two days per week compared with a more balanced weekly distribution was associated with similar risk reductions of incident lung cancer, while neither pattern was associated with reduced overall, prostate, breast, and colorectal cancers," the authors of the study wrote.
