Maternal protein intake during pregnancy and linear growth in the offspring.

ABSTRACT:

Background

Observational and experimental evidence demonstrates that protein intake in infancy programs linear growth. To our knowledge, few studies have examined prenatal maternal protein intake.

Objective

Our objective was to examine associations of maternal protein intake during pregnancy with offspring linear growth.

Design

We analyzed data from 1961 mother-child pairs in Project Viva. We assessed first- and second-trimester diet with the use of food-frequency questionnaires and analyzed protein intake as grams per kilogram prepregnancy weight per day. We used research measures of offspring length at birth and in infancy (∼6 mo), early childhood (∼3 y), and midchildhood (∼7 y), as well as clinical growth measures obtained from after birth through midchildhood. We
