Clinical Scorecard: Efficacy of Long-Term Physical Activity Interventions for Preventing Obesity-Related Cancers: Insights from a Simulated Target Trial in a Prospective US Cohort

At a Glance

Key Highlights

• Physical activity is linked to reduced risk of several obesity-related cancers.
• 13 cancer types are identified as obesity-related by the IARC.
• Recommended physical activity is 150–300 min of moderate-intensity or 75–150 min of vigorous-intensity per week.
• Two-thirds of adults in the US do not meet physical activity guidelines.
• Long-term adherence to physical activity recommendations may lower cancer incidence.

Guideline-Based Recommendations

Diagnosis

• Utilize self-reported questionnaires for physical activity assessment.
• Verify cancer diagnoses through medical records and state cancer registries.

Management

• Encourage adherence to physical activity guidelines for cancer prevention.

Monitoring & Follow-up

• Conduct biennial surveys to update lifestyle factors and cancer diagnoses.

Risks

• High costs and adherence challenges in long-term lifestyle interventions.

Patient & Prescribing Data

Adults aged ≥ 50 years, cancer-free at baseline.

Sustained moderate-to-vigorous physical activity is essential for reducing obesity-related cancer risk.

Clinical Best Practices

• Promote regular physical activity as part of cancer prevention strategies.
• Utilize validated tools for assessing physical activity levels.
