Trends in Weight-for-Length Among Infants in WIC From 2000 to 2014.

ABSTRACT:

Objectives

To describe the prevalence and secular trends of high weight-for-length among infants (ages, 3-23 months) in the biennial US Department of Agriculture Women, Infants, and Children Program and Participants Characteristic (WIC-PC) Survey from 2000 through 2014 (n = 16 927 120).

Methods

Weight-for-length was considered to be "high" if it was ≥2 SDs above the sex- and age-specific median in the World Health Organization growth standards. Poisson regression was used to calculate adjusted prevalence ratios.

Results

The overall prevalence of high weight-for-length increased from 13.4% in 2000 to 14.5% in 2004, remained constant until 2010, and then decreased by >2 percentage points (to 12.3%) through 2014. The prevalence of high weight-for-length was associated wi
