Article
This study considers how low birth weight (LBW) prevalence varies by race/ethnicity and maternal age and explores mechanisms that explain disparities. Results show that maternal age patterns in LBW risk for African Americans differ from Whites and foreign- and U.S.-born Hispanics. Background socioeconomic disadvantage, together with current socioec...
Article
Full-text available
Foreign- and U.S.-born Hispanic health deteriorate with increasing exposure and acculturation to mainstream U.S. society. Because these associations are robust to (static) socioeconomic controls, negative acculturation has become their primary explanation. This overemphasis, however, has neglected important alternative structural explanations. Exam...

There is a tremendous need for coordinated, accessible mental health services for people with serious mental illness who are in contact, or at high risk of involvement, with the criminal justice system. Despite inadequate equipment and personnel, the Texas criminal justice system increasingly provides care for individuals with serious mental illnes...
Article
Substance use disorder (SUD) stigma persists in society despite a movement toward people-first language in the mental health field. Stigma creates barriers to treatment and marginalizes already at-risk populations. Opioid use disorder (OUD) is of particular relevance to this discussion because recent increases in OUD can be traced to iatrogenic ori...

Substantial research has examined birth outcomes by race/ethnicity, noting not only disparities by race/ethnicity, but different maternal age patterns in low birth weight (LBW) prevalence. Few studies have examined these disparities among American Indian/Alaska Native (AI/AN) mothers, whose LBW prevalence is below the national average, despite subs...

While racial and ethnic differences in mortality are pervasive and well documented, less is known about how mortality risk varies by neighborhood socioeconomic status across racial and ethnic identity. We conducted a prospective analysis on a sample of adults living at or below 300% poverty with 8 years of the National Health Interview Survey (N =...
Conference Paper
Dust storms are a common phenomenon in West Texas. During dust storm events, air quality decreases and the concentration of aerosol particles increases. These particles are capable of penetrating deep into our lungs, therefore causing health problems. The effect of dust storms on human health is unclear; while some studies have observed an increase...
