Final answer:
The correct statement is that trauma is a significant cause of death and disability for people experiencing homelessness, contrary to options suggesting decreased health issues or infections.
Step-by-step explanation:
Among the given statements regarding the effects of homelessness on health, the accurate one is that trauma is a significant cause of death and disability. People experiencing homelessness are at a higher risk for a variety of health issues, including exposure to violence and trauma, which can lead to death and disability. The lifestyle associated with homelessness does not lessen the incidence of peripheral vascular disease or hypertension; in fact, it may exacerbate those and other health conditions. Similarly, crowded living conditions often associated with homelessness do not decrease but rather increase the risk for exposure to infections. The incidence and virulence of infections among people experiencing homelessness are not decreasing but are likely to be higher due to factors such as limited access to healthcare, inadequate nutrition, and challenging living conditions.
