Analysing Obesity Epidemicity and Endemicity: Introducing New Quantitative Indices

As obesity becomes more and more common, it will get (or may already have) converted from an epidemic to an endemic. This opinion piece discusses these epidemiological definitions in the context of obesity and proposes three obesity epidemicity indices to quantify their indices. It discusses the rationale behind using such ratios to measure endemicity. The discussion notes how the different ratios give markedly divergent results and call for greater attention to this aspect of obesity epidemiology.
