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 with sex (higher among boys), race-ethnicity (highest among American Indians/Alaskan Natives), and with both age (positive) and family income (inverse). The secular trends, however, were fairly similar within categories of these variables. From 2010 to 2014, the prevalence of high weight-for-length decreased in 40 states and 3 (of 5) US territories, with the largest decreases seen in Puerto Rico (-9 percentage points) and Kentucky (-7 percentage points), and the largest increase (+2 percentage points) seen in West Virginia. CONCLUSIONS:Although the current results cannot be considered representative of infants in the populations, the prevalence of a high weight-for-length has decreased among infants in WIC-PC since 2010. These decreases were similar across categories of most characteristics, but there were substantial differences across jurisdictions, possibly reflecting differences in policy and local programs that target maternal and infant health.

Project description:BackgroundUSDA's Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides expert-chosen supplemental foods to improve the diets and health of low-income infants and children <5 y of age, but dietary behaviors of WIC participants are not well characterized.ObjectiveThe purpose of this analysis was to examine differences in food consumption patterns between WIC participants and nonparticipants.MethodsFITS 2016 is a nationwide cross-sectional study of children <4 y (n = 3235). Data were weighted to provide US population-representative results. Children were categorized as WIC participants or nonparticipants, with the latter divided into lower- and higher-income nonparticipants. Group differences were assessed via the Wald test (demographics) and Rao-Scott modified chi-square test (breastfeeding prevalence). Differences in percentage consuming WIC-provided and selected other foods between WIC participants and nonparticipants were evaluated with the use of ORs and 95% CIs.ResultsWIC infants were less likely to breastfeed than were higher-income nonparticipants at 0-5.9 mo (45% compared with 74%) and less likely than both nonparticipant groups at 6-11.9 mo (30% compared with 49-60%). WIC 6- to 11.9-mo-olds were more likely to consume infant cereals and vegetables than were lower-income nonparticipants. WIC 12 to 23.9-mo-olds were more likely to drink whole milk (which WIC provides at this age) than were nonparticipants (72% compared with 59-64%), whereas WIC participants 24-47.9 mo were more likely to drink low- and nonfat milks (which WIC provides at this age) than were nonparticipants (45% compared with 13-22%). WIC participants 6-47.9 mo were more likely to drink juice than were nonparticipants.ConclusionsContinued improvements in early dietary patterns are warranted for WIC and non-WIC children. Breastfeeding among WIC participants is a continuing challenge. Findings suggest that baby-food cereals, vegetables, and fruits (all provided by WIC) contribute importantly to WIC infants' diets, whereas WIC children are more likely to use lower-fat milks after 2 y of age than are non-WIC participants.
