Discuss three of the seven uses and applications of epidemiology. How can descriptive epidemiology (person, place, time) be used to study health and illness and predict future trends?




Epidemiology –Topic 1 DQ 2-

Epidemiological information that is generated from different epidemiologic methods is used in numerous ways, including making individual decisions, assessing the health of communities, and searching for causes (Vargas-Prada et al., 2016). One of the primary uses of epidemiology is to evaluate the health of communities. Public health nurses and other public health professionals utilize epidemiologic information as the foundation of all the decisions that they make related to policy development and implementation of policies to improve public health. Another use of epidemiology is to assist in the making of individual decisions. Most individuals rely on epidemiologic information to make various decisions affecting their health. For instance, when an individual decides to eat a healthy diet consisting of all fruits and vegetables and be more physically active, they are utilizing information from epidemiological assessment of risks to certain behaviors either consciously or unconsciously. Epidemiologists consistently provide information to help the general public make more healthy decisions in their day-to-day lives (Vargas-Prada et al., 2016). The third primary use of epidemiology is to search for causes. A lot of epidemiologic research is therefore devoted to evaluating various causal factors that influence the risk of disease. One of the main functions of epidemiologic research is to identify the causes of illnesses so that the appropriate public health actions can be adopted (Vargas-Prada et al., 2016).

Descriptive epidemiology, which includes time, place, and person, can be utilized to study health and illness and predict future trends because it allows epidemiologists to view different patterns related to the health of communities. Descriptive epidemiology allows epidemiologist to evaluate the extent and patterns of public health problems and to eventually create detailed descriptions of the health of a population that can be easily communicated to populations (Kim et al., 2021).
