In considering factors that contribute to back pain, which would be least within an individual's control to change?

Ageing is considered the factor least within an individual's control to change because it is a natural and inevitable process that occurs over time. As people age, physical changes occur in the body, including degeneration of tissues, decreased bone density, and loss of muscle mass, which can contribute to back pain. While individuals can take steps to manage their overall health as they age, the passage of time and its effects on the body cannot be halted or reversed.

In contrast, physical activity level, weight management, and body mechanics are aspects that individuals can actively influence through their choices and behaviors. For example, engaging in regular exercise can strengthen the back and core muscles, proper weight management can reduce strain on the spine, and using correct body mechanics during lifting or moving tasks can help prevent injury. These are all actionable steps that can contribute to reducing the risk of back pain.
