Direct estimates of national-level obesity prevalence by age, sex, and year from the NHES, HDTC, and schools data.

The dots represent point estimates from the NHES, and the x’s represent point estimates from the HDTC; the vertical lines represent the associated 95% confidence intervals. The HDTC data does not distinguish females and males, so the figure shows estimates for both sexes combined. The lines for the period 2013–2019 are prevalence estimates from schools data.
