Advanced age is considered a significant risk factor for surgical site infections due to several physiological changes that occur as individuals age. Older adults often have compromised immune systems, resulting in a reduced ability to fight infections. Additionally, there may be underlying comorbidities, such as diabetes or vascular diseases, which can further inhibit the healing process and increase the likelihood of infection. The skin's elasticity and integrity may also decline with age, making it more susceptible to surgical wounds becoming infected.

In contrast, the other options do not directly correlate with increased risks for surgical site infections. Low blood sugar can lead to other complications but is not typically recognized as a direct risk for infection. High protein intake generally supports wound healing and recovery, offering a protective benefit rather than posing a risk. Regular exercise is known to improve overall health and can boost the immune system, thereby reducing the risk of infections post-surgery.
