Background: Obesity is a substantial contributor to rising rates of insulin resistance but is not well understood among children. Insulin resistance is known to be a precursor to type 2 diabetes. Given the rising rates in childhood obesity and type 2 diabetes among children, screening would likely be beneficial. A universal school-based screening approach is ideal for gathering information about health risks among children but the costs and time burdens associated with this approach can be limiting.

Purpose: To consider results from a school-based cardiovascular screening program to characterize students who present with the Acanthosis Nigricans (AN) marker in terms of their height, weight, and BMI percentiles and by gender distinctions.

Significance: These findings are important for conceptualizing how a school-based screneing program can inform greater understanding of obesity and insulin resistance outcomes among children.

Methodology: Cross-sectional results from a universally-screened sample of 5,732 kindergarten and second grade students who participated in the school-based screening project -L.I.F.E. Project were used in this study. Student height, weight, and body mass index percentiles for age and gender were collected. Insulin resistance was measured based on the presence of pigmented skin at the base of the neck - AN.

Results: Children who presented with the AN marker had significantly greater heights (p<.001), weights (p<.001), and BMIs (p<.01) than children who did not have the marker (figures will be provided). Gender differences were also noted with boys (p<.001) having heavier weights than girls in both cohorts.

Learning Objectives:
1. Describe and discuss a school-based screening approach to assessing childhood obesity and insulin resistance 2. Explain health characteristics of children who present with a pre-marker of insulin resistance compared to Acanthosis Nigricans (AN) to those who do not present with the marker. 3. Identify a position for school-based obesity risk screening and potential options for treatment.
