Trends in junk food consumption among US children and adults, 2001-2018.

ABSTRACT:

Background

Trends in junk food consumption, a risk for obesity, are not well established.

Objectives

We examined national trends in types of junk food (excluding beverages) and their sources (grocery, restaurants, schools, etc.), overall and in population subgroups.

Methods

We assessed 29,970 children (aged 2-19 y) and 44,501 adults (aged ≥20 y) with 24-h dietary recall data from 9 NHANES cycles (2001-2002 to 2017-2018). Trends in junk food were assessed over time using 1-d values for individuals with single recalls and 2-d means for others.

Results

From 2001 to 2018, percent energy (%E) from junk food remained stable for children (from 18.1% to 17.5%, P-trend = 0.25) and decreased for adults (14.1% to 13.0%, P-trend = 0.002). Among children, increases occurred
