What type of information is included in a patient's social history?

The correct choice highlights information that is commonly included in a patient's social history. Social history encompasses various lifestyle factors that can affect health and treatment. Specifically, it includes details about habits such as smoking and alcohol consumption, as these factors can significantly influence a patient's overall health and the management of any medical conditions. Exercise habits are also a key component, as they relate to the patient’s physical activity levels and general wellness.

The other options contain elements that do not specifically pertain to social history. While referring physician information and insurance details are important in a medical context, they relate more to the patient's medical management and administrative aspects rather than their lifestyle and social habits. Additionally, social security numbers are sensitive personal identifiers and not part of social history. By focusing on the indicated factors, the correct option provides a comprehensive view of the social determinants of health relevant to patient care.
