The Health Of Haitian Schoolchildren: Longitudinal Effect Of Annual Visits On Growth, Jamarie Geller, Mary Starrs, Andrew Bartholomew, Sara Kaliszak, Jeri Kessenich

Journal of Refugee & Global Health

Objectives: Haiti has one of the highest rates of childhood undernutrition in the world, devastating overall health. This study focuses on the growth of children offered longitudinal healthcare by Kids Health for Haiti, using BMI to indicate developmental and nutritional status. Objectives include collecting baseline prevalence data, examining the longitudinal impact of longitudinal interventions, and discussing future investigation and programming areas.

Methods: A retrospective longitudinal observational chart review on 245 students over a six-year period analyzing height, weight, and BMI. All data was collected as part of routine health provision and underwent statistical analysis using a single-subject design.

Results:46.3%, …

Examining The Temporal Directionality Between Teaching Behavior And Affect In High School Students., Bridget Cauley

Electronic Theses and Dissertations

Previous empirical studies demonstrate a cross-sectional association between teaching behaviors and students’ positive and negative affect and depressive symptoms. However, only one study comprised only of middle school students has examined the temporal direction of these associations, meaning the temporal direction of associations for high school students remains unclear. Therefore, this two-wave study with high school students investigated the temporal direction of the associations between teaching behaviors and students’ positive and negative affect. Participating students from one public high school (N = 188; 88.8% White; 69.7% female) completed the Teaching Behavior Questionnaire and the Positive Affect and Negative Affect …

Generalized Estimating Equation Based Zero-Inflated Models With Application To Examining The Relationship Between Dental Caries And Fluoride Exposures., Sheng Xu

Electronic Theses and Dissertations

In the study of dental caries, the number of caries is frequently characterized by over-dispersion and excessive zeros. In addition, the numbers of caries from the same subject are correlated. Zero-Inflated (ZI) regression models, such as ZI-Poisson (ZIP), ZI-Negative Binomial (ZINB), have been developed to account for the excessive zeros in count data. However, the existing zero-inflated models assume that the counts are uncorrelated. On the other hand, Generalized Estimating Equations (GEE) have been developed in the literature to estimate the parameters while accounting for the correlations of observations from the same subject. However, the GEE models incorporating excessive zero …

Emotional Distress In Older Adults With Cancer : A Multilevel Longitudinal Study., Tara J. Schapmire

Electronic Theses and Dissertations

Data from the Health and Retirement Study (HRS) were used to examine factors that influence emotional distress in older adults with cancer, arid to learn whether these distress trajectories are different from older adults without cancer. The model investigated the influence of life course factors, internal, external and health-related resources on distress over eight years among a nationally representative sample of older adults ages 50-91. Methods: This longitudinal panel study tested a multilevel random intercept multinomial ordered categorical model with a two-nested-Ievel structure using empirical Bayes Markov chain Monte Carlo (MCMC) estimation. The model examined individual differences in distress over …
