Higher physical activity levels, measured by average acceleration, show a causal link to significantly lower risks of common cancers. This human factors research insight is drawn from a 2020 study published in Nature Communications. Using Two-sample mendelian randomization (mr) analysis using genetic data. with Data from UK Biobank (approx. 500,000) and GWA consortia, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should shift from 'comfort-centric' design to 'activity-centric' design to improve long-term user physiological health.

Key Findings

  • 01A one standard deviation increase in average acceleration reduced breast cancer risk by 49%.
  • 02A one standard deviation increase in average acceleration reduced colorectal cancer risk by 34%.
  • 03The findings were consistent across estrogen-positive breast cancer and colon cancer specifically.

Application

Design takeaway

Designers should shift from 'comfort-centric' design to 'activity-centric' design to improve long-term user physiological health.

How to apply

Implement 'nudges' in product interfaces that reward movement or design physical environments that make the 'active' choice the most convenient one.

Project actions

  • 01Use this as a justification for a 'Health and Wellbeing' design brief.
  • 02Reference this when discussing the 'Physiological Factors' section of your project.
  • 03Consider designing a product that gamifies movement to reduce sedentary behavior.

Method & Evidence

AimTo determine if the association between physical activity and lower risks of breast and colorectal cancer is causal using Mendelian randomization.
MethodTwo-sample Mendelian randomization (MR) analysis using genetic data.
ProcedureResearchers used summary genetic data from the UK Biobank and GWA consortia to analyze the relationship between genetically predicted physical activity (average acceleration) and cancer incidence.
SampleData from UK Biobank (approx. 500,000) and GWA consortia
ContextPublic health and preventative medicine in the UK and international populations.

Strengths & Limitations

Strengths

  • +Large sample size
  • +Causal rather than just correlational evidence

Limitations

Students may find it hard to measure 'cancer risk' directly, so they should use 'activity levels' or 'heart rate' as a proxy in their own testing.

Reliability & validity

High validity due to the Mendelian Randomization method which reduces confounding factors common in observational studies.

Think critically

If a product is ergonomically 'comfortable' but encourages sitting for 8 hours, is it actually a 'good' design according to this health data?

05

Design Principles

"Health-Proactive Design: Products should inherently require or encourage physical exertion to mitigate long-term physiological risks."

In design, understanding physiological factors involves designing products and environments that promote health and prevent disease. This research provides a quantitative health-based justification for designers to prioritize 'active design' and wearable technology that encourages movement.

06

What This Means for Your Design

Scientists found that being more active actually causes a lower risk of cancer. This means designers have a responsibility to make products that keep people moving instead of sitting still.

Paragraph starter

According to Papadimitriou et al. (2020), increased physical activity (measured by acceleration) has a causal link to reducing breast and colorectal cancer risks by 34-49%. This highlights the critical role of physiological human factors in design, suggesting that products must actively discourage sedentary behavior to support long-term user health.
