Brief summary

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.

Detailed description

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.

Primary

MeasureTime frameDescription
ObesityOne day. The body measures data were collected, in the Mobile Examination Center (MEC), by trained health technicians.: NHANES collects objective physical examination data for each respondent in the sample, in mobile examination centers for standardization purposes. Body Mass Index (BMI) was calculated as weight in kilograms divided by height in meters squared, and then rounded to one decimal place. Participants were classified as obese using World Health Organization cut-offs for BMI (i.e. ≥30 kg/m2).
