What health issue does routine screening for STIs aim to prevent?

Routine screening for sexually transmitted infections (STIs) primarily aims to prevent the unintended consequences associated with sexual health, which include the transmission of infections and unintended pregnancies. By identifying STIs early, healthcare providers can initiate timely treatment to reduce the risk of complications, such as infertility, chronic pain, and transmission to partners. Additionally, by addressing STIs, providers help minimize the risk of complications during pregnancy and delivery, ultimately contributing to better health outcomes for both the parent and child.

In contrast, other options focus on unrelated health issues. Heart disease and diabetes, cancer and obesity, or asthma and allergies do not directly relate to STIs, as these conditions stem from different etiologies and risk factors. Therefore, they do not fall within the scope of what routine STI screening aims to achieve.
