Racial/ethnic and Gender Inequalities in Third Grade Children's Self-perceived STEM Competencies.

Studies have sought to understand the underrepresentation of women and racial/ethnic minority groups in STEM, but less attention has been paid to primary school students. Using data from a nationally-representative sample, this study identified factors influencing US third-grade children's self-perceived competencies in math and science, while controlling for their actual abilities. Results indicate that girls had degraded self-perceptions of their math competencies compared to boys, but similar self-rated science competencies.

Lifetime cancer risks from hazardous air pollutants in US public school districts.

Background: Children are sensitive to the health impacts of environmental contaminants, but research assessing outdoor environmental exposures for children and schools is underdeveloped. There are no national-level studies examining geographical and social disparities in air pollution exposure for children in school districts. Focusing on school districts is important because they are meaningful decision-making entities for schools.

Is there a Hispanic Health Paradox in Sensitivity to Air Pollution? Hospital Admissions for Asthma, Chronic Obstructive Pulmonary Disease and Congestive Heart Failure Associated with NO and PM in El Paso, TX, 2005-2010.

Study Objective: Linkages between pollution and morbidity have been observed in numerous studies. But race/ethnicity has been underemphasized as a modifier of that association, and few studies have tested for a Hispanic Health Paradox in sensitivity to air pollution.

Methods: Daily asthma, chronic obstructive pulmonary disease (COPD) and congestive heart failure (CHF) hospital admissions in El Paso, Texas were studied in age groups and insurance groups.
