Increased portion sizes from energy-dense foods affect total energy intake at eating occasions in US children and adolescents: patterns and trends by age group and sociodemographic characteristics, 1977-2006.

ABSTRACT:

Background

Larger portion sizes of foods and beverages could affect overall energy intake at meals and promote overeating.

Objective

We investigated trends in portion sizes of energy-dense foods and energy intakes at eating occasions in US children and adolescents.

Design

Four US nationally representative surveys from 1977 to 2006 were analyzed (n = 31,337). We measured trends in portion sizes (kcal, g, and mL) of selected foods [sugar-sweetened beverages (SSBs), salty snacks, desserts, French fries, burgers, pizzas, and Mexican fast foods] and energy intake (kcal) at eating occasions during which selected foods were consumed. Trends were reported by age group (2-6-, 7-12-, and 13-18-y-olds), sex, and socioeconomic status.

Results

In 2003-2006, the selected foo
