Mortality predictors are factors or variables that are used to predict the likelihood of an individual dying within a certain time frame or from a specific cause. These predictors can include demographic factors such as age, gender, and socioeconomic status, as well as health-related factors such as chronic diseases, lifestyle choices, and genetic predispositions. Researchers use mortality predictors to understand and predict mortality rates in populations, identify high-risk individuals who may benefit from targeted interventions, and improve overall public health outcomes. By studying mortality predictors, researchers can gain valuable insights into the complex relationship between various factors and mortality outcomes.
