Which factor related to back pain is considered to be within an individual's control to change?

Obesity is considered within an individual's control because it can be managed and modified through lifestyle changes, such as diet and exercise. Weight management plays a significant role in preventing and alleviating back pain, as excess weight can place additional strain on the back and spine. By adopting a healthy lifestyle, individuals can significantly decrease their risk of developing back pain related to obesity.

In contrast, genetics encompasses inherited traits that cannot be changed, making it an uncontrollable factor. Ageing is a natural process that brings about changes in the body, including degeneration of bones and muscles, and is also beyond an individual's control. Occupational hazards are external conditions related to work environments that may contribute to back pain, but these factors are generally set by employers and the nature of the job, rather than being something an individual can modify on their own.
