The investigators will assess the heterogeneity of obese individuals in the United States to help researchers, clinicians and policymakers to establish goals for obesity treatment and identify whether differing interventions may be needed.

Guidelines for obesity set common targets for interventions and goals around weight loss, and randomized trials and epidemiologic studies of obesity tend to consider obesity to be a homogeneous entity . The investigators will analyze data from the 2011-2012 wave of the NHANES. Obesity will be defined as having a body mass index greater than or equal to 30 Kg/m2. The investigators aim to identify obese sub-groups according to demographic factors, clinical conditions and behavioral characteristics. Results of this type of analysis will shed light on an important gap in the way that obesity interventions and guidelines are developed and will be an important step in beginning the discussion towards this important area.
