Introduction: Assessing nutrition knowledge in four-year-olds, a developmental stage marked by limited attention spans and varying comprehension abilities, is challenging with traditional methods. A reliable test is pivotal for establishing a foundation for future health interventions. We evaluated a 13-question nutrition and healthy habits test in Pre-K4 children to assess reliability and sensitivity to detect differences.

Methods: Calculations included Cronbach's alpha, kappa coefficient, McNemar analysis by item, and Bland-Altman plots for test-retest differences. Mixed model regression assessed the questionnaire's sensitivity by sex and association with age. Item response theory (IRT) models were employed, generating latent abilities for students and individual …

Research Symposium

Background: Early diagnosis of type 2 diabetes (T2D) can delay its vascular complications, but the active search for T2D results in inefficient use of resources. Simple methods like anthropometry or clinical history could help prioritize laboratory testing in individuals with risk of T2D. We evaluated non-invasive clinical measurements to pre-screen for new T2D patients.

Methods: We used the 2017-2018 NHANES database as the discovery cohort, and identified age, sex, BMI, waist circumference, and family history of T2D (FHD) as predictor variables. Risk of new T2D was analyzed using odds ratios with logistic regression. The diagnostic accuracy was calculated using ROC …
