Background: In the United States, Black women experience preterm birth (PTB; <37 weeks gestation) at more than 1.5 times the rate of non-Hispanic White women. Social determinants of health including the neighborhood environment have been recognized as contributing to the risk of PTB. Due to historical segregation, Black women are more likely to live in neighborhoods with higher levels of neighborhood disorder compared with White women. Perceived neighborhood disorder appears to be a risk factor for maternal psychological distress in Black women and psychological distress has mediated the association between neighborhood disorder and the risk for PTB. However, the biological pathways underpinning these associations are not clear. Objective: We examined the associations among neighborhood disorder; psychological distress; DNA methylation of six stress-related, glucocorticoid candidate genes (AVP, CRH, CRHBP, FKBP5, HSD11B2, NR3C1); and gestational age at birth among 44 Black pregnant women. Methods: Women who were 18–45 years old and 8–18 weeks gestation had blood drawn and completed questionnaires measuring perceived neighborhood disorder, neighborhood crime, and psychological distress. Results: Three CpG sites were associated with neighborhood disorder (cg03405789 [ CRH ], cg14939152 and cg15910486 [ NR3C1 ]). One CpG site, cg03098337 (FKBP5) was associated with psychological distress. Three of the identified CpG sites were located within gene CpG islands or shores—areas at which DNA methylation is known to affect gene transcription. Conclusion: These findings warrant further research to clarify intermediate biological pathways and potential biomarkers to identify women at risk for PTB. Identification of PTB risk early in pregnancy would allow for interventions to prevent PTB. [ABSTRACT FROM AUTHOR]

Preterm birth (PTB; <37 weeks gestation) rates have increased for 5 of the last 6 consecutive years in the United States. These rates are particularly alarming for U.S. non-Hispanic Black women who give birth prematurely at 1.5 times the rate of non-Hispanic White women. Previous research suggests that psychological stress is associated with PTB in Black women. However, the biological pathways by which stress alters birth timing are not clear. We examined DNA methylation (DNAm) in peripheral blood leukocytes in 6 glucocorticoid, stress-related genes in 44 (22 PTB; 22 term birth) pregnant Black women. Four cytosine-phosphate-guanine (CpG) sites were identified as differentially methylated (p < 0.05) between women with PTB and women with term births. The ability to identify stress-related biological markers that are associated with PTB among Black women would provide a critical step toward decreasing the PTB disparity among these women. Future studies should include larger sample sizes and gene expression analyses of the stress-related biological pathways to PTB. [ABSTRACT FROM AUTHOR]

Objective: This study evaluated the effects of a social determinants of health (SDH) screening tool and service referral on emergency department (ED) use among patients at a Federally Qualified Health Center primary care clinic. Study design: Quasi‐experimental. Sample: Three‐hundred and eleven English‐speaking patients 18 years and older. Measures: The Core 5 SDH screening tool consists of five yes/no items assessing food, housing, utilities, transportation, and safety needs. The number of ED visits 3 months before and after the intervention were collected from electronic health records. Intervention: The research team administered the Core 5 SDH screening tool and if desired, referred patients with an identified need for SDH services. Results: Approximately 43% of patients reported a SDH need with food insecurity most prevalent (62.2%). The number of ED visits was significantly lower 3 months post‐intervention compared to 3 months before for the 125 participants who wanted and received the SDH service referral (IRR = 0.64, 95% CI = 0.41, 0.99) and for the 35 participants who reported receiving some/all of the needed services at the 2‐week follow‐up (IRR = 0.36, 95% CI = 0.17, 0.76). Conclusions: Addressing patients' SDH needs may reduce ED visits, lower healthcare costs, and ultimately, improve health. [ABSTRACT FROM AUTHOR]

Background: Exposure to racism and associated adversities, such as poverty, is hypothesized to contribute to racial inequities in health via stress and immune pathways. Furthermore, the effects of adversity may be more salient during sensitive developmental periods. Our study examined racial differences in stress and immune biomarkers during adolescence and the effects of exposure to economic adversity at distinct developmental time periods and cumulatively in accounting for potential racial differences. Methods: Secondary analysis of the Adolescent Health and Development in Context study was conducted. Data were derived from self-administered surveys; interviews; smartphone-based, geographic-explicit ecological momentary assessment; stress biomarkers (evening salivary cortisol over six nights and hair cortisol); and immune biomarkers (salivary shedding of Epstein-Barr virus [EBV] DNA among EBV-positive adolescents). Current socioeconomic status measures included annual household income and caregiver education. Caregivers also reported experiences of bankruptcy, difficulty paying bills, receipt of food stamps/Supplemental Nutrition Assistance Program/electronic benefit transfer, and job loss when the child was of ages birth-5 years, 6-10 years, and 11 years or older. An affirmative response to any item was defined as exposure to economic adversity for that developmental time period (yes/no). A cumulative economic adversity measure was calculated as the sum of exposures across developmental periods (0 = never exposed to 3 = exposed across all time periods). Descriptive and multivariable regression analyses were conducted, accounting for covariates. Results: Black/African American adolescents had higher salivary cortisol concentration, higher hair cortisol concentration, and an increased odd of salivary shedding of EBV DNA compared to White adolescents. Racial differences were not attenuated by the current socioeconomic status or economic adversity (developmental period or cumulatively). Discussion: Our study provides evidence that stress and immune biomarkers differ by race as early as adolescence and may be one pathway through which racism and associated adversities contribute to racial health inequities. Further research on the contribution of multiple adversities beyond poverty to racial inequities in physiological stress and health is critical for informing effective prevention and intervention efforts.

Low birth weight is an ongoing public health problem with severe consequences for those affected, including early morbidity and mortality and elevated risk for lifelong deficits in cognitive function. These deficits can be ameliorated by early intervention in many cases. To contribute to criteria for earlier identification of at-risk children prior to the onset of delays or deficits, we examined relationships between three gene candidates— SLC6A4, BDNF, COMT— and cognitive outcomes at school age in a secondary analysis of existing data from a nationally representative cohort. Single nucleotide polymorphism rs4074134, a variant of BDNF, and a rare insertion/deletion in the intron region of SLC6A4 were significant predictors of cognitive performance. Our final model predicted 17% of the variance in composite cognitive test scores among children with low birth weight at school age (F = 96.36, p <.001, R 2 =.17). Specifically, children homozygous for cytosine at rs4074134 scored.62 standard deviations higher on a measure of global cognition than children with one or more thymine. Similarly, children with an extra-long copy number variant of SLC6A4 scored.88 standard deviations higher than children who had one or more short forms of the gene. These findings support the potential for an approach to identifying children with low birth weights who are most at need of early intervention services. Future research should focus on validation of these findings in an independent sample and confirmation of the biological mechanisms through which these genes influence cognitive development.

Few studies have examined the effects of parental incarceration (PI) on outcomes above and beyond other risk and adverse childhood experiences (ACEs). The objectives of this study were to (1) the associations between PI and mental health problems (attention, externalizing, internalizing, and total behavioral problems) and (2) the mediating role of current socioeconomic status and cumulative ACEs. An observational and cross-sectional design was employed. Analyses included hierarchical multivariable linear regression modeling. The analytic sample included 613 adolescents (11-17 years). On average, youth exposed to PI experienced three times as many ACEs compared with youth unexposed. Youth exposed to PI were more likely to have behavioral problems than their unexposed peers. The main effect for all models was attenuated by current economic hardship as well as exposure to increasing numbers of ACEs. Exposure to PI can be viewed as a marker of accumulative risk for intervention since youth impacted by PI are more likely to experience behavioral difficulties and associated adverse childhood experiences. Due to the associated adversity that impact youth exposed to PI, mental health providers need to be able to identify and screen for symptoms associated with trauma. [ABSTRACT FROM AUTHOR]

Objective: Medical care alone cannot adequately improve population health or eliminate inequities; social determinants of health (SDH) must be addressed. This study's purpose was to describe the research, teaching, service, and clinical practice activities implemented by RWJF Nurse Faculty Scholars to act on the SDH. Design: A cross-sectional survey design was used with a sample of RWJF Nurse Faculty Scholars, chosen because they were provided specialized mentoring, grants, and other support that allowed them to explore SDH. Results: Respondents (n = 57) addressed SDH in their research (86.0%), teaching (68.4%), service (66.7%), and clinical practice (33.3%). Leading research foci were quality of health care (56.1%), social and physical environmental stressors (54.4%), and access to health care services (49.1%). Leading SDH areas in teaching were discrimination in society against vulnerable populations (54.4%), quality of health care received by vulnerable populations (50.9%), and vulnerable populations' access to health care services (50.9%). Service activities included addressing discrimination against diverse populations. Leading SDH areas in clinical practice were quality of health care received by vulnerable populations (28.1%), vulnerable populations' access to health care services (22.8%), and discrimination in society against vulnerable populations (19.3%). Respondents also addressed SDH through personal mentoring (71.9%); efforts to recruit and/or retain underrepresented faculty (59.6%); developing a diverse pipeline of nurses (59.6%); and participation on a diversity committee (40.4%). Conclusion: The RWJF Nurse Faculty Scholars were able to leverage their awards to address SDH; however, further research is needed to assess the impact of the SDH work conducted. Knowledge from this study can be used as a road map for SDH elements and areas of professional work that nurses and other health professionals could address SDH in research, teaching, service, and practice.

Background: Black-White disparities in adolescent health are widespread and thought to be explained, in part, by exposure to chronic stress. Cortisol assayed from hair is increasingly recognized as a valid and reliable measure for chronic physiological stress, but the feasibility of collecting hair among large probability samples of diverse adolescents is unknown. Purpose: The aim of the study was to investigate participation in hair collection for cortisol analyses in a probability sample of racially and socioeconomically diverse adolescents, including the extent to which sociodemographic factors and adverse exposures were associated with participation. Methods: The study included a probability sample of 516 adolescents conducted in conjunction with a prospective cohort study on adolescent health. Data were collected over 1 week via in-home interviews, ecological momentary assessment, global positioning system methods, and in-home hair collection at the end of the week. Results: Of the 516 eligible youth, 471 (91.3%) participated in the hair collection. Of the 45 youth who did not provide hair samples, 18 had insufficient hair, 25 refused, and 2 did not participate for unknown reasons. Multivariable logistic regression results indicated that non-Hispanic Black youth were less likely than their non-Hispanic White peers to participate due to insufficient hair or refusal (OR =0.24, 95% CI [0 .09,0.60]). Despite lower rates of participation, the proportion of Black youth in the participating sample was representative of the study area. No significant differences in participation were found by other sociodemographic characteristics or adverse exposures. Conclusions: Hair collection for cortisol measurement is feasible among a probability sample of racially and socioeconomically diverse adolescents. Hair cortisol analyses may accelerate research progress to understand the biological and psychosocial bases of health disparities. [ABSTRACT FROM AUTHOR]

Objectives. We examined relationships between neighborhood social disorganization and trichomoniasis among young US adults. Methods. We employed multilevel logistic regression modeling with secondary data from wave III of the National Longitudinal Study of Adolescent Health (2001-2002). The dependent variable-trichomoniasis-was measured via urine testing. The measures for neighborhood social disorganization were derived from the 2000 US Census-racial and ethnic composition, concentrated poverty, and residential instability. The sample comprised 11370 individuals across 4912 neighborhoods. Results. Trichomoniasis was more likely in neighborhoods with higher concentrations of Black residents (adjusted odds ratio [AOR]=1.16; 95% confidence interval [CI]=1.03, 1.30). However, this association was mediated by neighborhood concentrated poverty. Furthermore, young adults who lived in neighborhoods with higher concentrations of poverty were significantly more likely to have trichomoniasis (AOR=1.25; 95% CI=1.07, 1.46). Neither immigrant concentration nor residential instability was significantly associated with trichomoniasis. Conclusions. These findings strengthen the evidence that neighborhood structural conditions are associated with individual sexually transmitted infection (STI) acquisition. Research is needed to explore the mechanisms through which these conditions influence STI. In addition, STI-prevention programs that include structural interventions targeting neighborhood disadvantage are needed. [ABSTRACT FROM AUTHOR]

OBJECTIVE: This study examined the relationships among nurse fatigue, individual nurse factors, and the practice environment in the inpatient setting. BACKGROUND: Nurse fatigue affects the quality of care provision on inpatient units. Scant literature exists regarding how aspects of the practice environment relate to nurse fatigue. METHODS: A cross-sectional, correlational design was used in this survey study of 175 neonatal intensive care unit nurses from multiple hospitals. Data were collected using the Checklist Individual Strength questionnaire and the Practice Environment Scale of the Nursing Work Index. Hierarchical regression analysis was performed to examine the relationships. RESULTS: Higher fatigue was significantly associated with more hours worked, fewer hours of sleep, a physical or mental contributor to fatigue, and a recent distressing patient event. Lower fatigue was significantly associated with better nurse manager ability, leadership, and support. CONCLUSIONS: Nurse fatigue may be diminished with organizational and individual strategies. Developing tactics for nurse managers to better support staff members after a recent distressing patient event is indicated. [ABSTRACT FROM AUTHOR]
