The term 'omics' refers to a broad field of study in biology that ends with the suffix "-omics," such as genomics, proteomics, and metabolomics. These fields focus on the collective characterization and quantification of pools of biological molecules that translate into the structure, function, and dynamics of an organism or organisms. In the context of Epidemiology, 'omics' technologies provide in-depth insights into the molecular mechanisms underlying health and disease in populations.
