Learning Objective 1: 1. The learner will be able to describe distinguishing attributes of the World Health Organization international growth charts for children aged 0 – 59 months.

Learning Objective 2: 2. The learner will be able to describe why using a universal tool in researching childhood obesity enhances the significance of the results.

Obesity threatens a child’s immediate and long term health. The prevalence in the U.S. increased dramatically over the past three decades; doubling among children 2 – 5 years of age and tripling among those 6 – 11 years old, with an estimated national annual cost of $147 billion to manage and treat the consequences.  Children of minority and low-income families are more likely to be obese compared to the general population. The 2010 U.S. Census reveals a significant increase in the minority children population with Hispanics representing the largest absolute increase.  Primary care providers need evidence based guidelines to screen and identify at risk children.  Policy makers need evidence that informs federally funded programs that support children and families.  However the myriad facets of obesity present significant challenges for identifying mutable factors which reduce the risk for or prevent obesity.  Studies examining breastfeeding’s association with a reduced risk of childhood obesity report equivocal results.  Differing definitions, populations, designs, metrics, and tools impede development of robust evidence.  The accelerated growth in the Hispanic population coupled with its increased prevalence of childhood obesity represent a significant need for further study of breastfeeding’s relationship to reducing risk of childhood obesity in this population. The CDC recently recommended universal use the 2006 WHO international growth charts for children aged <24 month, which are based on standards establishing growth of the breastfed infant as the norm.   The purpose of this study is to examine the association between length of exclusive breastfeeding and obesity at age 3 among Hispanic children in low SES families.  This poster presents a secondary data analysis research project which proposes using the Pediatric Nutrition Surveillance System (PedNSS) database.  This national database receives almost 86% of its data from WIC programs and therefore offers a representational population from which to sample.
