Which condition is listed as affecting mobility in older adults?

• A. Diabetes mellitus
• B. Hypertension
• C. Osteoporosis
• D. Obesity

Answer: (C)

Osteoporosis directly affects mobility in older adults by weakening bones and increasing the risk of fragility fractures. When the bones are fragile, even minor events or falls can cause hip, spine, or wrist fractures. Vertebral fractures can lead to height loss and a stooped posture, with chronic pain and reduced lung capacity, all of which limit movement and independence. Fractures from osteoporosis often result in prolonged immobility and a downward cycle of deconditioning.

Diabetes mellitus can influence mobility over time through nerve damage and circulation issues, but it’s not the primary factor listed for mobility impairment in aging. Hypertension itself doesn’t directly limit movement, and obesity can impede mobility due to joint strain and deconditioning, but osteoporosis most directly explains mobility loss through fragility fractures and spinal deformities.
