Answer #1

Ans)Epidemiology:

- It is the study of the distribution and determinants of health related states or events in specific populations and the application of this study to control health problems.

- Epidemiology is a discipline that has a crucial role in describing health status, identifying risk factors, and analyzing relationships between health and different hazardous agents.

- Epidemiology is helpful to community/public health nurses for describing the health status of a population and the factors that contribute to its well-being,for targeting aggregates at risk of specific health conditions, and for evaluating the effectiveness of nursing interventions in populations.

- The natural history of a disease is influenced by characteristics of the people (host), agents (biologic, chemical, and physical), and environment that make up the epidemiologic triangle.

- Age, sex, race, social class, occupation, and marital status are demographic characteristics frequently used when describing human populations.

These factors contribute to variations in health status, health-related behaviors, and use of health care services.
