Which term refers to all individuals sharing a common health issue or characteristic?

The term that refers to all individuals sharing a common health issue or characteristic is "Population." In public health and nursing, a population is often defined as a group of individuals who share specific commonalities, such as a health condition, demographic features, or geographical area. Understanding the characteristics of a population is essential for developing effective health interventions, policy planning, and resource allocation.

In contrast, "Determinants of health" relate to the factors that influence the health status of individuals or populations, such as socioeconomic status, education, and environment, but do not define a group of individuals. "Therapeutic relationship" refers to the professional rapport established between a nurse and patient, focusing on individual interactions rather than a broader group. "Evidence-informed practice" involves integrating clinical expertise with the best available evidence for healthcare decisions, which is a methodology rather than a term describing a group. Thus, "Population" is the most accurate term in this context.
