Which of the following is a risk factor for swimming induced pulmonary edema (SIPE)?

Swimming-induced pulmonary edema (SIPE) is a condition that can occur in individuals while swimming, particularly in open water. Various factors contribute to the risk of developing this condition.

The correct answer highlights being a female as a risk factor. Research indicates that males are generally at a higher risk for SIPE compared to females. However, being a female swimmer may also be considered a factor in certain studies, particularly regarding the physiological differences between genders and how the body may respond to the stressors associated with swimming, such as cold water immersion or intense exertion.

Living at high altitudes can increase the likelihood of developing SIPE due to lower oxygen availability, which may stress the respiratory system during swimming activities; however, this does not relate directly to gender. Swimming less than 1 mile does not typically present a significant risk factor since SIPE is more commonly associated with long or intense swimming sessions, especially under more extreme conditions like altitude or cold water.

In summary, identifying female gender as a risk factor reflects the complexity of SIPE, where both physiological and environmental components play critical roles in its development. This option emphasizes an understanding of how different factors can influence the risks associated with swimming.
