Which of the following is included in a subjective global assessment?

Subjective Global Assessment (SGA) is a clinical tool used by dietitians to evaluate a patient's nutritional status based on subjective criteria. Among the options provided, dietary intake plays a crucial role in this assessment. When conducting an SGA, health professionals gather information about the patient's dietary habits, including food preferences, portion sizes, frequency of meals, and any recent changes in dietary patterns. This information helps in identifying potential nutrient deficiencies or excesses and forms the basis for developing an appropriate nutrition care plan.

The other options have relevance but do not directly align with the core focus of a Subjective Global Assessment. For example, while physical activity level can influence nutritional needs, it is not a primary component in assessing nutritional status in the SGA framework. Medication history may provide insight into nutritional implications or potential interactions, but it is not centrally assessed in the SGA itself. Family medical history may have indirect effects on a patient's nutritional status through hereditary conditions but does not directly pertain to the immediate assessment of current dietary intake and habits.

Thus, dietary intake is the most critical aspect within a Subjective Global Assessment, as it provides essential insights into the patient’s nutritional adequacy and overall health.
