Abstract

Objective This study aimed to assess whether racial disparities in nulliparous, term, singleton, vertex cesarean delivery rates vary among hospitals of different type (academic vs. nonacademic), setting (urban vs. rural), delivery volume, and patient population. Study Design This is a retrospective cohort study including singleton term vertex live births in nulliparous Black and non-Hispanic White birthing people in California between 2011 and 2017. Cesarean delivery rates were obtained using birth certificate data and International Classification of Diseases, 9th/10th Revision codes. Risk of cesarean delivery was compared among Black versus White birthing people by hospital type (academic, nonacademic), setting (rural, suburban, urban), volume (< 1,200, 1,200-2,300, 2,400-3,599, ≥3,600 deliveries annually), and patient population (proportion Black-serving). Federal Information Processing codes were used to designate hospital setting. Risks were calculated using univariable and multivariable logistic regression and adjusted for birthing person age, body mass index, medical comorbidities, gestational age, labor type (spontaneous vs. induction), and infant birthweight. Results The sample included 59,441 Black (cesarean delivery rate: 30.2%) and 363,624 White birthing people (cesarean delivery rate: 26.1%). Black birthing people were significantly more likely than White birthing people to have a cesarean delivery across nearly all hospital-level factors considered with adjusted relative risks ranging from 1.1 to 1.3. The only exception was rural settings in which the adjusted relative risk was 1.3 but did not reach statistical significance. Conclusion Black-White disparities in nulliparous, term, singleton, vertex cesarean delivery rates were persistent across all hospital-level factors we considered: academic status, rurality, delivery volume, and patient population. Furthermore, disparities existed at roughly the same magnitude regardless of hospital characteristics. These global increased risks likely reflect structural inequities in care, which contribute to disparities in pregnancy-related morbidity and mortality. These data should encourage providers, hospital systems, and quality collaboratives to further investigate racial disparities in cesarean delivery rates and develop strategies for eliminating them. Key Points Nulliparous Black birthing people are more likely than White to undergo cesarean delivery. This persists across hospitals of all academic status, rurality, delivery volume, and patient population. These findings likely reflect structural rather than institutional inequities in obstetric care.

Abstract

Background: Birthing people of color are more likely to deliver low birthweight and preterm infants, populations at significant risk of morbidity and mortality. Birthing people of color are also at higher risk for mental health conditions and emergency mental healthcare utilization postpartum. Although this group has been identified as high risk in these contexts, it is not known whether racial and ethnic disparities exist in mental healthcare utilization among birthing people who have delivered preterm. Objective: We sought to determine if racial and ethnic disparities exist in postpartum mental healthcare-associated emergency department visits or hospitalizations for birthing people with preterm infants in a large and diverse population. Study design: This population-based historic cohort study used a sample of Californian live-born infants born between 2011 and 2017 with linked birth certificates and emergency department visit and hospital admission records from the California Statewide Health Planning and Development database. The sample was restricted to preterm infants (<37 weeks’ gestation). Self-reported race and ethnicity groups included Hispanic, non-Hispanic Black, non-Hispanic Asian, non-Hispanic White, and non-Hispanic others. Mental health diagnoses were identified from the International Classification of Diseases Ninth and Tenth revision codes recorded in emergency department and hospital discharge records. Logistic regression analysis was used to estimate the association between mental health-related emergency department visits and rehospitalizations by race or ethnicity compared with non-Hispanic White birthing people and controlling for the following characteristics and health condition covariates: age, parity, previous preterm birth, body mass index, smoking, alcohol use, hypertension, diabetes, previous mental health diagnosis, and prenatal care. Results: Of 204,539 birthing people who delivered preterm infants in California, 1982 visited the emergency department and 836 were hospitalized in the first year after preterm birth for a mental health-related illness. Black birthing people were more likely to have a mental health-related emergency department visit and hospitalization (risk ratio, 1.8; 95% confidence interval, 1.5–2.0 and risk ratio, 1.9; 95% confidence interval, 1.5–2.3, respectively) within the first postpartum year than White birthing people. Hispanic and Asian birthing people were less likely to have mental health-related emergency department visits (adjusted risk ratio, 0.7; 95% confidence interval, 0.7–0.8 and adjusted risk ratio, 0.2; 95% confidence interval, 0.2–0.3, respectively) and hospitalizations (adjusted risk ratio, 0.6; 95% confidence interval, 0.5–0.7 and adjusted risk ratio, 0.2; 95% confidence interval, 0.1–0.3, respectively). When controlling for birthing people with a previous mental health diagnosis and those without, the disparities remained the same. Conclusion: Racial and ethnic disparities exist in emergency mental healthcare escalation among birthing people who have delivered preterm infants. Our findings highlight a need for further investigation into disparate mental health conditions, exacerbations, access to care, and targeted hospital and legislative policies to prevent emergency mental healthcare escalation and reduce disparities.

Abstract

Objectives: COVID-19 disproportionately affects racial/ethnic minorities and vaccine can help mitigate infection and transition, decrease rate of hospitalization, lower mortality rate, and control the pandemic. This study aims to examine disparities in COVID-19 vaccination rate by age among Whites, Hispanics, Blacks, and Asian Americans, and the modification effects by gender and education. Methods: We used seven waves of biweekly surveys from the Household Pulse Survey collected between July 21, 2021, and October 11, 2021. Results: Asians reported the highest, Blacks reported the lowest vaccination rate, and gender differences were minimal. Increasing age was associated with higher vaccination rate except for the oldest age group. The decline was from 84.4% (70-79 years) to 41.1% (80-88 years: 41.1%) among Hispanics and 92.8% to 69.6% among Asians. Educational effect was the most salient among younger adults with the largest gaps observed in Blacks. Among 18-29-year Black participants, the vaccination rates were 31.1% (confidence interval [95% CI]: 25.7-37.1) for high school or lower, 58.9% (95% CI: 54.2-63.5) for some college or associate degree, and 74.2% (95% CI: 69.4-78.5) for bachelor or higher degrees, leaving a 43.1% gap between the lowest and the highest education levels. The gaps in this age group were 33.7% among Whites, 32.1% among Hispanics, and 20.5% among Asian Americans. Conclusion: Our study advances the existing literature on COVID-19 vaccination by providing empirical evidence on the dynamic race/ethnic-age-education differences across racial/ethnic groups. The findings from our study provide scientific foundation for the development of more strategies to improve vaccination rate for the minority populations.

Abstract

Despite long-existing calls to address alarming racial/ethnic gaps in severe maternal morbidity (SMM), research that considers the impact of intersecting social inequities on SMM risk remains scarce. Invoking intersectionality theory, we sought to assess SMM risk at the nexus of racial/ethnic marginalization, weathering, and neighborhood/individual socioeconomic disadvantage. We used birth hospitalization records from California across 20 years (1997–2017, N = 9,806,406) on all live births ≥20 weeks gestation. We estimated adjusted average predicted probabilities of SMM at the combination of levels of race/ethnicity, age, and neighborhood deprivation or individual socioeconomic status (SES). The highest risk of SMM was observed among Black birthing people aged ≥35 years who either resided in the most deprived neighborhoods or had the lowest SES. Black birthing people conceptualized to be better off due to their social standing (aged 20–34 years and living in the least deprived neighborhoods or college graduates) had comparable and at times worse risk than White birthing people conceptualized to be worse off (aged ≥35 years and living in the most deprived neighborhoods or had a high-school degree or less). Our findings highlight the need to explicitly address structural racism as the driver of racial/ethnic health inequities and the imperative to incorporate intersectional approaches.

Abstract

Introduction: Maternal morbidity and mortality rates are on the rise in the United States, particularly among Black populations. Recently, there has been an uptick in research funding to identify and address root causes, particularly among at-risk groups. However, given the historical trauma experienced by Black populations in research settings, novel approaches built firmly on ethical principles and grounded in a framework of reproductive justice are necessary to minimize harm and center the research process on maintaining the dignity and respect of research participants. Methods: Ethical principles as outlined by the American Nurses Association, Black Mamas Matter Alliance, and federal research guidelines are reviewed within the context of conducting maternal mortality-focused research. In addition, community developed research frameworks and methodologies are presented and discussed within the research context. Conclusions: Black pregnant people have reported mistreatment during clinical encounters; therefore, intentional protections to promote safety must be considered in the research setting. Ethical principles must be considered when designing and implementing research initiatives focused on addressing maternal mortality risk in Black communities.

Abstract

Precision nutrition is an emerging concept that aims to develop nutrition recommendations tailored to different people's circumstances and biological characteristics. Responses to dietary change and the resulting health outcomes from consuming different diets may vary significantly between people based on interactions between their genetic backgrounds, physiology, microbiome, underlying health status, behaviors, social influences, and environmental exposures. On 11-12 January 2021, the National Institutes of Health convened a workshop entitled "Precision Nutrition: Research Gaps and Opportunities" to bring together experts to discuss the issues involved in better understanding and addressing precision nutrition. The workshop proceeded in 3 parts: part I covered many aspects of genetics and physiology that mediate the links between nutrient intake and health conditions such as cardiovascular disease, Alzheimer disease, and cancer; part II reviewed potential contributors to interindividual variability in dietary exposures and responses such as baseline nutritional status, circadian rhythm/sleep, environmental exposures, sensory properties of food, stress, inflammation, and the social determinants of health; part III presented the need for systems approaches, with new methods and technologies that can facilitate the study and implementation of precision nutrition, and workforce development needed to create a new generation of researchers. The workshop concluded that much research will be needed before more precise nutrition recommendations can be achieved. This includes better understanding and accounting for variables such as age, sex, ethnicity, medical history, genetics, and social and environmental factors. The advent of new methods and technologies and the availability of considerably more data bring tremendous opportunity. However, the field must proceed with appropriate levels of caution and make sure the factors listed above are all considered, and systems approaches and methods are incorporated. It will be important to develop and train an expanded workforce with the goal of reducing health disparities and improving precision nutritional advice for all Americans.

Abstract

Background: While pollution from vehicle sources is an established risk factor for preterm birth, it is unclear whether distance of residence to the nearest major road or related measures like major road density represent useful measures for characterising risk. Objective: To determine whether major road proximity measures (including distance to major road, major road density and traffic volume) are more useful risk factors for preterm birth than other established vehicle-related measures (including particulate matter <2.5 μm in diameter (PM2.5) and diesel particulate matter (diesel PM)). Methods: This retrospective cohort study included 2.7 million births across the state of California from 2011–2017; each address at delivery was geocoded. Geocoding was used to calculate distance to the nearest major road, major road density within a 500 m radius and major road density weighted by truck volume. We measured associations with preterm birth using risk ratios adjusted for target demographic, clinical, socioeconomic and environmental covariates (aRRs). We compared these to the associations between preterm birth and PM2.5 and diesel PM by census tract of residence. Results: Findings showed that whereas higher mean levels of PM2.5 and diesel PM by census tract were associated with a higher risk of preterm birth, living closer to roads or living in higher traffic density areas was not associated with higher risk. Residence in a census tract with a mean PM2.5 in the top quartile compared with the lowest quartile was associated with the highest observed risk of preterm birth (aRR 1.04, 95% CI 1.04, 1.05). Conclusions: Over a large geographical region with a diverse population, PM2.5 and diesel PM were associated with preterm birth, while measures of distance to major road were not, suggesting that these distance measures do not serve as a proxy for measures of particulate matter in the context of preterm birth.

Abstract

Although adolescent females with asthma are at increased risk for bullying, relationships between bullying at school and electronic bullying and demographics, mental health issues, and substance use have not specifically been studied in these young women. The purpose of this research was to examine such relationships among adolescent females with asthma. Complex sampling software was used to extrapolate frequencies and χ2 analyses to adolescent females with asthma. In this U.S. sample of adolescent females with asthma (n = 1,634), younger age, mental health issues, and substance use were significantly related to bullying at school and electronic bullying, while race/ethnicity and grade in school were significantly related only to bullying at school. In general, findings are consistent with previous research regarding relationships between bullying and risk factors among all U.S. adolescent females. Guidance by school nurses is needed to create effective supports for victimization reduction in this vulnerable group.

Abstract

Objectives: Among childbearing women, insurance coverage determines degree of access to preventive and emergency care for maternal and infant health. Maternal-infant dyads with dual burden of severe maternal morbidity and preterm birth experience high physical and psychological morbidity, and the risk of dual burden varies by insurance type. We examined whether sociodemographic and perinatal risk factors of dual burden differed by insurance type. Methods: We estimated relative risks of dual burden by maternal sociodemographic and perinatal characteristics in the 2007–2012 California birth cohort dataset stratified by insurance type and compared effects across insurance types using Wald Z-statistics. Results: Dual burden ranged from 0.36% of privately insured births to 0.41% of uninsured births. Obstetric comorbidities, multiple gestation, parity, and birth mode conferred the largest risks across all insurance types, but effect magnitude differed. The adjusted relative risk of dual burden associated with preeclampsia superimposed on preexisting hypertension ranged from 9.1 (95% CI 7.6–10.9) for privately insured to 15.9 (95% CI 9.1–27.6) among uninsured. The adjusted relative risk of dual burden associated with cesarean birth ranged from 3.1 (95% CI 2.7–3.5) for women with Medi-Cal to 5.4 (95% CI 3.5–8.2) for women with other insurance among primiparas, and 7.0 (95% CI 6.0–8.3) to 19.4 (95% CI 10.3–36.3), respectively, among multiparas. Conclusions: Risk factors of dual burden differed by insurance type across sociodemographic and perinatal factors, suggesting that care quality may differ by insurance type. Attention to peripartum care access and care quality provided by insurance type is needed to improve maternal and neonatal health.

Abstract

Objective: The objective was to investigate maternal and pregnancy characteristics associated with neonatal encephalopathy (NE). Study design: We queried an administrative birth cohort from California between 2011 and 2017 to determine the association between each factor and NE with and without hypothermia treatment. Results: From 3 million infants born at 35 or more weeks of gestation, 6,857 cases of NE were identified (2.3 per 1000 births), 888 (13%) received therapeutic hypothermia. Risk factors for NE were stronger among cases receiving hypothermia therapy. Substance-related diagnosis, preexisting diabetes, preeclampsia, and any maternal infection were associated with a two-fold increase in risk. Maternal overweight/obesity, nulliparity, advanced maternal age, depression, gestational diabetes or hypertension, and short or long gestations also predicted NE. Young maternal age, Asian race and Hispanic ethnicity, and cannabis-related diagnosis lowered risk of NE. Conclusions: By disseminating these results, we encourage further interrogation of these perinatal factors.

Abstract

Objective: Evaluate the risk of preterm (<37 weeks) or early term birth (37 or 38 weeks) by body mass index (BMI) in a propensity score-matched sample. Design: Retrospective cohort analysis. Setting: California, USA. Population: Singleton live births from 2011–2017. Methods: Propensity scores were calculated for BMI groups using maternal factors. A referent sample of women with a BMI between 18.5 and <25.0 kg/m2 was selected using exact propensity score matching. Risk ratios for preterm and early term birth were calculated. Main outcome measures: Early birth. Results: Women with a BMI <18.5 kg/m2 were at elevated risk of birth of 28–31 weeks (relative risk [RR] 1.2, 95% CI 1.1–1.4), 32–36 weeks (RR 1.3, 95% CI 1.2–1.3), and 37 or 38 weeks (RR 1.1, 95% CI 1.1–1.1). Women with BMI ≥25.0 kg/m2 were at 1.2–1.4-times higher risk of a birth <28 weeks and were at reduced risk of a birth between 32 and 36 weeks (RR 0.8–0.9) and birth during the 37th or 38th week (RR 0.9). Conclusion: Women with a BMI <18.5 kg/m2 were at elevated risk of a preterm or early term birth. Women with BMI ≥25.0 kg/m2 were at elevated risk of a birth <28 weeks. Propensity score-matched women with BMI ≥30.0 kg/m2 were at decreased risk of a spontaneous preterm birth with intact membranes between 32 and 36 weeks, supporting the complexity of BMI as a risk factor for preterm birth. Tweetable abstract: Propensity score-matched women with BMI ≥30 kg/m2 were at decreased risk of a late spontaneous preterm birth.

Abstract

Purpose: Home health care is one of the fastest growing health care sectors in the United States. However, little is known of differences in trends in quality performance between rural and urban home health agencies over time. This study aimed to examine disparities in quality performance between rural and urban home health agencies between 2014 and 2018. Methods: This is a cohort study using 2014-2018 national Home Health Compare data and Providers of Service Profile data, including 7,908 home health agencies, of which 1,537 were rural agencies. Quality performance measures included timely initiation of care, hospitalization, and emergency department (ED) visits. Two-level hierarchical regression models were used to identify rural-urban differences in these quality indicators over time when controlling organizational characteristics. Findings: Rural agencies were less likely to be for-profit and accredited, and more likely to be hospital-based, serve both Medicare and Medicaid beneficiaries, and have hospice programs. Rural agencies consistently outperformed on timely initiation of care over time, and urban agencies consistently outperformed on hospitalization and ED visits over time. These gaps between rural and urban agencies were steady over time except the gap in hospitalization, which slightly narrowed over time (Coef. = 0.11, P =.001 for urban and year interaction term). Conclusions: Significant differences exist in quality of care between rural and urban home health agencies and such differences have not been significantly narrowed over time. To reduce rural-urban disparities, policy makers should take into account unique challenges faced by urban and rural agencies when making policy decisions.

Abstract

More than 20% of school districts in the United States do not have policies on identification and case management for students with chronic health conditions (CHCs), suggesting that these students’ health needs may not be met during the school day. Prior research reports a gap in policy implementation and the actual provision or operationalization of the policy into action. While there is limited research on school health policies, little is known about the actual provision of the services that such policies indicate should be provided. Notably, the actual provision of health services in U.S. schools, particularly regarding CHC management and its association with school nurse employment, is underreported. Using data from the 2018 School Health Profiles (SHP) Survey, health services including administering daily medication, providing stock rescue medication, providing case management, facilitating community partnering, and providing disease-specific education were examined in California public secondary schools together with school nurse employment. Complex sampling analysis and chi-square statistics were used to examine the statistical associations. A significantly greater proportion of schools with a full- or part-time nurse compared with schools with no nurse provided: (1) daily medication administration (82.1% vs. 68.1%; p = .014); (2) case management services (75.8% vs. 62.0%; p = .031); (3) disease-specific education for parents and families (44.9% vs. 25.7%; p = .016); and (4) parent and student connection to health services in the community (83.7% vs. 72.2%; p = .035). Findings suggest that nationally representative data, such as SHP, contain important information for states to review regarding school health policies and provision of services. Further research needs to expand these findings to better understand school health policy and practice and its alignment with state and federal laws to support all children, especially those with CHCs.

Abstract

The increasing prevalence of chronic health conditions (CHCs) in school-aged children highlights the need to better understand school health services’ role regarding CHCs. Using U.S. nationally representative district-level data from the 2016 School Health Policies and Practices Study, we examined whether having policies on school nurses’ employment was associated with having policies on CHCs and whether having such policies varied by geographic location. Compared to districts without such employment policies, districts with such policies (52.3%) were significantly more likely to have CHC management policies. For each CHC policy examined, more than 20% of school districts did not have the CHC policy, with Northeast districts having the greatest proportion of such policies and West districts having the least. Thus, many students’ CHC needs may not be met at school. It is important for school nurses to play a key role in advocating for the development of school-based policies on CHCs.

Abstract

Objective: Our primary objective was to understand bullying as it pertains to middle school students with chronic physical or behavioral health conditions by examining it through the lens of school nurses. A second objective was to understand issues pertaining to implementation of New York’s bullying prevention law with a focus on these same students. Methods: We employed a qualitative descriptive design with purposive sampling to explore perspectives of school nurses in New York State who worked in public middle schools. Using a semi-structured protocol, we conducted audio-recorded telephone interviews that were transcribed for subsequent thematic analysis. Results: Twelve nurses agreed to be interviewed. Results revealed participants’ understanding of bullying as related to students with chronic health conditions, especially those with behavioral health issues. Results also showed nurses’ limited understanding of New York’s bullying prevention law and missed opportunities for school nurses as champions of students with chronic health conditions who are bullied. Conclusions: Education and health care professionals should collaborate to disseminate information to school personnel about the risks of bullying for students with chronic health conditions and operationalize plans for prevention.

Abstract

Head and neck cancer (HNC) is the seventh most common cancer worldwide, the majority being oral squamous cell carcinoma. Despite advances in cancer diagnosis and treatment, the survival rate of patients with HNC remains stagnant. The cancer-nerve interaction has been recognized as an important driver of cancer progression. Schwann cells, a type of peripheral glia, have been implicated in promoting cancer cell growth, migration, dispersion, and invasion into the nerve in many cancers. Here, it is demonstrated that the presence of Schwann cells makes oral cancer cells more aggressive by promoting their proliferation, extracellular matrix breakdown, and altering cell metabolism. Furthermore, oral cancer cells became larger, more circular, with more projections and nuclei following co-culturing with Schwann cells. RNA-sequencing analysis in oral cancer cells following exposure to Schwann cells shows corresponding changes in genes involved in the hallmarks of cancer and cell metabolism; the enriched KEGG pathways are spliceosome, RNA transport, cell cycle, axon guidance, signaling pathways regulating pluripotency of stem cells, cAMP signaling, WNT signaling, proteoglycans in cancer and PI3K-Akt signaling. Taken together, these results suggest a significant role for Schwann cells in facilitating oral cancer progression, highlighting their potential as a target to treat oral cancer progression.

Abstract

Objective: Physical and psychosocial effects of oral cancer result in long-term self-management needs. Little attention has been paid to survivors' self-efficacy in managing their care. Study goals were to characterise self-care self-efficacy and evaluate socio-demographics, disease, attitudinal factors and psychological correlates of self-efficacy and engagement in head and neck self-exams. Methods: Two hundred thirty-two oral cancer survivors completed measures of socio-demographics, self-care self-efficacy, head and neck self-exams and attitudinal and psychological measures. Descriptive statistics characterised self-efficacy. Hierarchical regressions evaluated predictors of self-efficacy. Results: Survivors felt moderately confident in the ability to manage self-care (M = 4.04, SD = 0.75). Survivors with more comorbidities (β = −0.125), less preparedness (β = 0.241), greater information (β = −0.191), greater support needs (β = −0.224) and higher depression (β = −0.291) reported significantly lower self-efficacy. Head and neck self-exam engagement (44% past month) was relatively low. Higher preparedness (OR = 2.075) and self-exam self-efficacy (OR = 2.606) were associated with more engagement in self-exams. Conclusion: Many survivors report low confidence in their ability to engage in important self-care practices. Addressing unmet information and support needs, reducing depressive symptoms and providing skill training and support may boost confidence in managing self-care and optimise regular self-exams.

Abstract

Background: Cancer pain prevalence remains high, and variance in self-efficacy for managing pain may explain why some patients experience greater pain severity. Aim: This study explored perceptions of self-efficacy in relation to cancer pain severity and treatment related characteristics. Method: A descriptive cross-sectional survey was administered to 50 cancer outpatients. Data analysis involved descriptive and correlational statistical analyses. Results: Self-efficacy to manage pain was significantly associated with time since diagnosis and ability to deal with frustration, and inversely associated with pain severity level. A large proportion of patients reported low satisfaction self-managing their pain. Most patients reported independently self-managing their cancer pain; however, satisfaction with pain management was low for a large proportion of patients. Time since cancer diagnosis and ability to deal with frustration due to cancer pain were positively associated with cancer pain self-efficacy, whereas pain self-efficacy had a significant inverse correlation with cancer pain severity. Conclusions: Enhancing self-efficacy to self-manage under-treated cancer pain is important with implications for improving pain outcomes and quality of life. Further investigation on unmet needs and preferences for cancer pain self-management support is warranted.

Abstract

Objective Sexual minority men (e.g., gay, bisexual, and other men who have sex with men) experience stigma and sexual minority stress, which are theorized to drive negative health outcomes. Sexual minority men with treated HIV display persistent immune dysregulation, which could be amplified by sexual minority stress responses to potentiate cellular aging. Methods This cross-sectional study included 52 sexual minority men living with HIV who had undetectable viral load (<40 copies/mL) and biologically confirmed recent methamphetamine use. Participants completed measures assessing sexual minority stress and openness about sexual minority status (i.e., outness). DNA methylation-derived outcomes included the following: the extrinsic epigenetic age acceleration clock, telomere length, naive CD4+ T-helper cells, and naive CD8+ T-cytotoxic/suppressor cells. Results After adjusting for negative affect and recent stimulant use, higher sexual minority stress was associated with a faster extrinsic epigenetic age acceleration clock (β = 0.29, p =.030), shorter telomere length (β =-0.43, p =.002), and fewer naive CD4+ (β =-0.57, p <.001) and naive CD8+ T cells (β =-0.57, p <.001). Greater outness was associated with higher naive CD4+ (β = 0.32, p =.030) and naive CD8+ T cells (β = 0.38, p =.008) as well as lower plasma interleukin 6 (β =-0.33, p =.027). Conclusions Sexual minority stress processes are associated with markers of cellular aging and inflammation in methamphetamine-using sexual minority men living with HIV. Longitudinal research should elucidate biobehavioral mechanisms linking sexual minority stress processes with accelerated cellular aging in those with and without HIV.

Abstract

Background: At the start of the COVID-19 pandemic, HIV experts suggested that an increase in mental health diagnoses and substance use among people living with HIV (PLHIV) may be an unintended consequence of COVID-19 mitigation efforts (e.g., limiting social contact). We evaluated short-term trajectories in binge drinking, marijuana, and recreational drug use in a prospective cohort of PLHIV. Methods: Data (N = 2121 PLHIV) consist of survey responses on substance use behaviors from two pre-COVID-19 (October 2018-September 2019) and one COVID-19-era (April 2020-September 2020) timepoints within the MACS/WIHS Combined Cohort Study (MWCCS). We conducted group-based trajectory models, triangulated with generalized linear mixed models, to assess changes in binge drinking, daily marijuana use, and recreational drug use at the start of the pandemic. Controlling for age and race/ethnicity, we tested whether trajectories differed by sex and early-pandemic depressive symptoms, loneliness, and social support. Results: Group-based trajectory models yielded two trajectory groups for binge drinking (none vs. any), marijuana (none/infrequent vs. daily), and recreational drug use (none vs. any). Binge drinking and recreational drug use decreased at the beginning of the pandemic. Generalized linear mixed model supported these trends. Consistent with prior research, male sex and having depressive symptoms early pandemic were positively associated with each substance use outcomes. Social support was inversely associated with recreational drug use. Conclusions: Contrary to hypotheses, problematic substance use behaviors decreased from pre-pandemic to the post-pandemic follow-up in our sample of PLHIV. Ongoing surveillance is needed to assess whether this pattern persists as the pandemic continues.

Abstract

Objectives: This study examined the relationships between social capital, perceived neighborhood environment, and depressive symptoms among older adults living in rural China, and the moderating effect of self-rated health (SRH) in these relationships. Participants: A quota sampling method was applied to recruit 447 participants aged 60 years and older in rural communities in Jilin province, China in 2019. Measurements: Depressive symptoms were measured by the Center for Epidemiologic Studies Depression Scale. Structural equation modeling was used to build latent constructs of social capital and test the proposed model. Multiple group analysis was used to test the moderation effects. Results: Cognitive social capital and structural social capital were both associated with depressive symptoms controlling for participants' demographics, socioeconomic status, and health status. After adding perceived environment variables in the model, the relationship between cognitive social capital and depressive symptoms became nonsignificant, while structural social capital remained became a significant factor (β = -.168, p <.01). Satisfaction with health care was significantly associated with depressive symptoms among those with poor SRH (β = -.272, p <.01), whereas satisfaction with security and transportation were strongly associated with depressive symptoms among those with good SRH (security: β = -.148, p <.01; transportation: β = -.174, p <.01). Conclusions: Study findings highlighted the importance of social capital and neighborhood environment as potential protective factors of depressive symptoms in later life. Policy and intervention implications were also discussed.

Abstract

Perinatal illicit substance use is a nursing and public health issue. Current screening policies have significant consequences for birthing individuals and their families. Racial disparities exist in spite of targeted and universal screening policies and practices. Thus, new theoretical approaches are needed to investigate perinatal illicit substance use screening in hospital settings. The purpose of this analysis is to evaluate the social construction of target populations theory in the context of perinatal illicit substance use screening. Using the theoretical insights of this theory to interrogate the approaches taken by policy makers to address perinatal illicit substance use and screening provides the contextual framework needed to understand why specific policy tools were selected when designing public policy to address these issues. The analysis and evaluation of this theory was conducted using the theory description and critical reflection model.

Abstract

Objectives: Social isolation imposes risks to an individual's psychological well-being. However, few studies have examined the role of resilience on these associations among older Chinese Americans, the fastest-growing aging population across all racial/ethnic groups in the United States. We aim to examine the associations of social isolation with indicators of psychological well-being and the mediating role of resilience in these associations. Methods: Data were derived from 398 Chinese older adults aged over 55 residing in Honolulu, Hawaii, in 2018. Psychological well-being was measured by psychological distress, life satisfaction, and happiness. Multivariate linear regressions and ordered logistic regressions were conducted. Results: Social isolation was positively associated with psychological distress and negatively associated with life satisfaction and happiness (all p < 0.05). By contrast, resilience was associated with lower levels of psychological distress and higher levels of life satisfaction and happiness (all p < 0.05). Moreover, the findings supported our hypothesis that resilience mediated the association between social isolation and psychological well-being. With regard to social isolation, resilience contributed to 32.0% of its association with distress, 24.9% of the association with life satisfaction, and 16.3% of the association with happiness. Conclusion: Our findings revealed a significant association between social isolation and psychological well-being and the mediating role of resilience in the association of older Chinese Americans in Hawaii. The study findings expand our understanding of psychological resources in older Chinese Americans and emphasize the importance of developing intervention programs to foster social connection and resilience among an understudied population.

Abstract

Social support is considered an imperative component of healthy aging and has been found to foster resilience against mental illness. The National Institute of Health has called for research to investigate social support as a protective mechanism for health disparities populations, including LGBT older adults. This integrative review is the first to comprehensively examine the characteristics of social networks maintained by LGBT adults age 50 and older. A comprehensive electronic literature search was conducted for articles published before September 2019. A manual search was also conducted among the reference lists of articles yielded. Articles that presented empirical data, described communities and social networks, and examined participants who self-identify as LGBT adults over the age of 50 were included. Nineteen articles met inclusion criteria. The Convoy Model of Social Relations was used to synthesize findings into categories of structure (size, composition, geographic proximity, and contact frequency), function (instrumental and emotional), and quality (positive and negative) of social support. Results indicate that diverse social networks are protective against age-related illness; intersectional minorities, and individuals who struggle with homophobia in the family of origin are at greatest risk for low network diversity, functional support deficits, and risks to psychological well-being. This review identifies that future research is needed to investigate the role that online social networks play in mediating social support needs in this population.
