Which intervention does the USPSTF recommend to help prevent falls in older adults who are at increased risk?

• A. Vitamin supplementation
• B. Exercise interventions
• C. Bed rest
• D. Avoiding physical activity

Answer: (B)

Regular, targeted exercise helps prevent falls in older adults who are at increased risk by improving balance, strength, and coordination. Programs that combine balance training, resistance or gait training, and sometimes tai chi or multi-component approaches have consistently shown reductions in fall frequency and fall-related injuries in community-dwelling seniors. This is why the USPSTF recommends offering exercise or physical therapy-based interventions to those at higher risk.

Vitamin supplementation does not provide a reliable, general fall-prevention benefit for all older adults; any benefit is mainly limited to individuals with a true deficiency. Bed rest promotes deconditioning and weakness, which can increase fall risk, and avoiding physical activity would likewise raise the chance of falling. So the intervention with proven preventive value is engaging in structured exercise.
