Incidence of obesity across adulthood in the United States, 2001-2017-a national prospective analysis.

ABSTRACT:

Background

In the United States, the prevalence of obesity among adults has increased 3-fold since the 1980s, but patterns of incidence of new cases of obesity are not known.

Objectives

To examine the incidence of new cases of obesity: overall, by demographic and educational subgroups, by weight status, and changes during this century.

Methods

We analyzed adult (≥20 y) anthropometric records from the US nationally representative Panel Study of Income Dynamics from 2001 to 2017. Among those not having obesity (body mass index, BMI, ≥30 kg/m²) at first observation, we used Poisson models to estimate the incidence of obesity [cases/1000 person-years (PYs)] and incidence rate ratio (IRR).

Results

Among 13,888 adults followed for 115,797 PYs, the incidenc
