Which health outcome is most directly studied in epidemiology?

Epidemiology is primarily concerned with the study of health-related states or events within populations. This includes the distribution, patterns, and determinants of health and disease conditions. By focusing on health-related states or events, epidemiology seeks to understand how various factors can influence the occurrence and spread of diseases, as well as the impact of these conditions on different populations.

While factors such as dental hygiene practices, nutrition habits, and physical fitness levels may contribute to or affect health outcomes, they themselves are not the core focus of epidemiological studies. Instead, these factors can be considered as variables that may influence the health-related states or events that epidemiologists are monitoring. Therefore, the health outcomes directly studied in epidemiology encompass the broader implications of these factors, making the study of health-related states or events the most pertinent aspect of epidemiologic research.
