View abstract on PubMed
Summary
This summary is machine-generated.Colorectal cancer (CRC) screening may lead to modest unfavorable lifestyle changes. Integrating lifestyle counseling into CRC screening programs could be beneficial for participants’ long-term health.
Area Of Science
- Oncology
- Preventive Medicine
- Public Health
Background
- Uncertainty exists regarding the impact of cancer screening on participant lifestyle choices.
- The Norwegian Colorectal Cancer Prevention trial investigated long-term effects of screening on lifestyle.
Purpose Of The Study
- To investigate the long-term effects of colorectal cancer (CRC) screening on participant lifestyle changes.
- To assess if CRC screening influences adherence to healthy lifestyle recommendations.
Main Methods
- A randomized controlled trial comparing flexible sigmoidoscopy screening with no screening.
- Lifestyle factors (weight, smoking, exercise, diet) and a total lifestyle score were assessed over 11 years in a subgroup of participants aged 50-55.
- Outcomes were compared between screening and control arms, and between screening attendees with positive versus negative findings.
Main Results
- Total lifestyle scores improved in both screening and control groups over 11 years.
- The improvement in lifestyle score was smaller in the screening group compared to the control group (adjusted difference -0.05, p=0.03).
- Screening attendees with positive findings showed less favorable lifestyle score changes than those with negative findings (adjusted difference -0.16, p<0.001).
Conclusions
- Colorectal cancer screening is associated with modest, potentially unfavorable, lifestyle changes.
- Lifestyle counseling may be a valuable component of cancer screening programs to mitigate negative lifestyle impacts.
