Trends in energy intake among adults in the United States: findings from NHANES.

ABSTRACT:

Background

Energy intake is a key determinant of weight.

Objective

Our objective was to examine trends in energy intake in adults in the United States from 1971-1975 to 2009-2010.

Design

The study was a trend analysis of 9 national surveys in the United States that included data from 63,761 adults aged 20-74 y.

Results

Adjusted mean energy intake increased from 1955 kcal/d during 1971-1975 to 2269 kcal/d during 2003-2004 and then declined to 2195 kcal/d during 2009-2010 (P-linear trend < 0.001, P-nonlinear trend < 0.001). During the period from 1999-2000 to 2009-2010, no significant linear trend in energy intake was observed (P = 0.058), but a significant nonlinear trend was noted (P = 0.042), indicating a downward trend in energy intake. Significant decreases
