Socioeconomic position and the influence of food portion size on daily energy intake in adult females: two randomized controlled trials.

ABSTRACT:

Background

Reducing portion sizes of commercially available foods could be an effective public health strategy to reduce population energy intake, but recent research suggests that the effect portion size has on energy intake may differ based on socioeconomic position (SEP).

Objective

We tested whether the effect of reducing food portion sizes on daily energy intake differed based on SEP.

Methods

Participants were served either smaller or larger portions of food at lunch and evening meals (N = 50; Study 1) and breakfast, lunch and evening meals (N = 46; Study 2) in the laboratory on two separate days, in repeated-measures designs. The primary outcome was total daily energy intake (kcal). Participant recruitment was stratified by primary indicators of SEP; highest educ
