What are two potential underlying causes of low-back pain in obese individuals?

1. Altered posture; lack of spinal mobility

2. Excess weight; improper lifting techniques

3. Lack of exercise; poor diet

4. Weak core; muscle imbalance

The correct answer is: Altered posture; lack of spinal mobility

The choice highlighting altered posture and lack of spinal mobility as potential underlying causes of low-back pain in obese individuals is indeed a valid answer. In the context of obesity, excess body weight can significantly affect posture, as the additional weight can lead to postural adjustments to maintain balance, often resulting in increased strain on the lumbar spine. This alteration may manifest as a forward tilt of the pelvis or excessive curvature of the lower back, both of which can contribute to pain. Moreover, obesity can limit spinal mobility due to accumulated fat around the abdomen and lower back, possibly leading to stiffness and decreased range of motion. This reduced mobility can exacerbate discomfort and pain, as the muscles and ligaments supporting the spine may not function optimally when they are not regularly engaged through movement. Other options, while relevant to various health and physical conditions, do not specifically address the direct association of low-back pain with obesity in the same manner. Factors like excess weight and improper lifting techniques certainly play a role, as does having a lack of exercise and poor diet, but the direct link to posture and spinal mobility strongly correlates with the unique mechanics of how obesity affects musculoskeletal health. Therefore, the focus on altered posture and lack of spinal mobility rightly highlights key issues that stem from
