Longitudinal effects of emerging adults’ self-presentation on social networking sites on fear of missing out
Positive self-presentation on social networking sites shapes fear of missing out through both protective and risk pathways, with basic psychological needs satisfaction functioning as a protective factor and online upward social comparison operating as a risk mechanism that is amplified among individuals with higher levels of neuroticism. In contrast, authentic self-presentation on social networking sites reduces fear of missing out primarily thro…
The effect of disease uncertainty on stress perception among parents of critically ill children in the Picu
Disease uncertainty is a significant factor contributing to stress in parents of children admitted to the PICU. It affects their choice of coping styles, which in turn impacts their stress levels. This study highlights the importance of addressing disease uncertainty and coping strategies to reduce stress in parents of critically ill children and improve family-centered care in the PICU
The Association Between Vitamin D Deficiency and Diabetes in Adult African Americans and Whites
Objective The primary objective of this cross-sectional study is to investigate the association between vitamin D deficiency (VDD) and diabetes and see if this association is the same for adult (age ≥ 20) African Americans (AAs) and Whites. The secondary objective is to examine the distribution of the 25-hydroxyvitamin D test among AAs and Whites and to evaluate the appropriateness of using the same cut-off point for both groups to diagnose VDD. …
Predicting Low-Level Childhood Lead Exposure in Metro Atlanta Using Ensemble Machine Learning of High-Resolution Raster Cells
Low-level lead exposure in children is a major public health issue. Higher-resolution spatial targeting would significantly improve county and state-wide policies and programs for lead exposure prevention that generally intervene across large geographic areas. We use stack-ensemble machine learning, including an elastic net generalized linear model, gradient-boosted machine, and deep neural network, to predict the number of children with venous b…
Influence of Mask Wearing during Covid-19 Surge and Non-Surge Time Periods in Two K-12 Public School Districts in Georgia, USA
This study highlights the need for more layered prevention strategies and policies that take into consideration local community transmission levels, age of students, and vaccination coverage to ensure that students remain safe at school while optimizing their learning environment
Increased Risk of Sub-Clinical Blood Lead Levels in the 20-County Metro Atlanta, Georgia Area—A Laboratory Surveillance-Based Study
Lead (Pb) is a naturally occurring, highly toxic metal that has adverse effects on children across a range of exposure levels. Limited screening programs leave many children at risk for chronic low-level lead exposure and there is little understanding of what factors may be used to identify children at risk. We characterize the distribution of blood lead levels (BLLs) in children aged 0-72 months and their associations with sociodemographic and a…
