Health risk: an adverse event or negative health consequence due to a specific event, disease, or condition. For example, the health risks of obesity include diabetes, joint disease, increased likelihood of certain cancers, and cardiovascular disease. All of these consequences are related to obesity and are therefore health risks associated with obesity. A health risk may be related to genetic conditions, chronic diseases, certain occupations or sports, lifestyle factors, or any number of events or situations.
