Diversity supplements: An underutilized opportunity to improve the diversity of the health sciences research workforce

Purpose

This paper describes the process developed at the University of Pittsburgh to increase the number of NIH-funded Diversity Supplements.

Method

The authors formed a Diversity in Academia Workgroup where we created the infrastructure and process to increase the number of Diversity Supplements. Each year, the Office of Sponsored Programs provided a list of grants that would be eligible to submit a Diversity Supplement. We surveyed the Principal Investigators inquiring about their interest in working with a trainee on a Diversity Supplement. If yes, we included their information in a database we built so that trainees could search for eligible research studies. The Diversity Deans then identified underrepresented faculty and postdoctoral researchers. We invited Program Officers from NIH to participate in a panel presentation for trainees, which was well attended.

Results

The number of Diversity Supplements awarded to Pitt researchers has significantly increased from 7 in 2020 to 10 in 2021 and to 15 in 2022. Six more have been awarded in the first half of 2023.

Conclusions

We created the Diversity in Academia Workgroup with the goal to increase the number of Diversity Supplements at the University of Pittsburgh and in so doing, increase the diversity in the biomedical research workforce. While challenging, we know the critical importance and benefits of increased diversity at the University, and we have made significant strides toward this goal.

Examining the Cross-sectional Association Between Neighborhood Conditions, Discrimination, and Telomere Length in a Predominantly African American Sample

Disproportionate exposure to adverse neighborhood conditions and greater discrimination may contribute to health disparities among African Americans (AAs). We examined whether adverse neighborhood conditions, alone or in conjunction with discrimination, associate with shorter leukocyte telomere length among a predominantly AA cohort. The sample included 200 residents from two low-income neighborhoods (96% AA; mean age = 67 years). Perceived neighborhood conditions and discrimination were surveyed in 2018, and objective neighborhood conditions (total crime rate, neighborhood walkability, ambient air pollution (PM2.5, black carbon)) were collected in 2017/2018. Relative telomere length (T/S; ratio of telomeric DNA to a single-gene copy) was assessed from blood samples. Linear regression models estimated the main effects of each neighborhood condition and discrimination and their interactions on the T/S ratio. Less walkable neighborhoods were associated with shorter telomeres. Higher air pollution (PM2.5) was associated with shorter telomeres among those experiencing greater discrimination. Findings highlight the importance of understanding the intersecting influences of historic and contemporary sources of systemic racism and how they contribute to accelerated aging among adults.

Examining demographic and psychosocial factors related to self-weighing behavior during pregnancy and postpartum periods

Black childbearing individuals in the US experience a higher risk of postpartum weight retention (PPWR) compared to their White counterparts. Given that PPWR is related to adverse health outcomes, it is important to investigate predictors of weight-related health behaviors, such as self-weighing (i.e., using a scale at home). Regular self-weighing is an evidence-based weight management strategy, but there is minimal insight into sociodemographic factors related to frequency. The Postpartum Mothers Mobile Study (PMOMS) facilitated longitudinal ambulatory weight assessments to investigate racial inequities in PPWR. Our objective for the present study was to describe self-weighing behavior during and after pregnancy in the PMOMS cohort, as well as related demographic and psychosocial factors. Applying tree modeling and multiple regression, we examined self-weighing during and after pregnancy. Participants (N = 236) were 30.2 years old on average (SD = 4.7), with the majority being college-educated (53.8%, n = 127), earning at least $30,000 annually (61.4%, n = 145), and self-identifying as non-Hispanic White (NHW; 68.2%, n = 161). Adherence to regular self-weighing (at least once weekly) was highest among participants during pregnancy, with a considerable decline after giving birth. Low-income Black participants (earning < $30,000) were significantly less likely to reach a completion rate of ≥ 80% during pregnancy (AOR = 0.10) or the postpartum period (AOR = 0.16), compared to NHW participants earning at least $30,000 annually. Increases in perceived stress were associated with decreased odds of sustained self-weighing after delivery (AOR = 0.79). Future research should consider behavioral differences across demographic intersections, such as race and socioeconomic status, and the impact on efficacy of self-weighing.

An Equity Response to COVID-19 in Allegheny County, Pennsylvania: The Development and Work of the Black Equity Coalition

From the onset of the pandemic in the United States, racial disparities in COVID-19 outcomes have been evident. In April 2020, several events prompted a concerned group of colleagues to form the Black Equity Coalition (BEC), a Black-led coalition in Allegheny County, Pennsylvania, which brings together professionals from multiple sectors who aim to ensure an equitable response to the COVID-19 pandemic. Several significant milestones have been achieved, and this article describes the development, functioning, and outcomes of the Coalition in the first 15 months of operation (April 2020-June 2021). COVID-19 was the reason for such an unprecedented effort, but this BEC infrastructure will be needed long after COVID-19 is controlled. In addition to short-term activities and reactive measures to prevent and mitigate COVID-19 in Black populations, the BEC is serving as a crucial link between government, health care stakeholders, and communities to produce long-term systemic change.

Correlates of COVID-19 Vaccine Uptake in Black Adults Residing in Allegheny County, PA

Introduction

Efforts to address vaccine uptake and access among black adults will be relevant for continued coronavirus disease 2019 (COVID-19) eradication efforts and can be transferable to other prevention efforts in future pandemics. This study investigated factors related to COVID-19 vaccine uptake and access among black residents in Allegheny County, PA.

Methods

Surveys were administered electronically from October 2021 to January 2022 to black Allegheny County residents aged 18 and older. Questions included thoughts on COVID mitigation strategies (e.g., masking, social distancing), vaccination status, intention to vaccinate children, trust of COVID-19 information sources and vaccines, family needs, access to support services, and social media use to access information. Descriptive statistics and significant correlates of being vaccinated using adjusted logistic regression models are reported.

Results

Of the overall sample (N=397), the majority were fully vaccinated (n=306, 77%). Fully vaccinated participants were more likely to be female (62.5%, p=0.010), age 60 years or older (34.3%, p=0.0002), have some college education (23.2%, p<0.0001), and be employed full time (50.0%, p=0.0001) compared with nonvaccinated individuals. Among the unvaccinated participants (n=91), the primary reason was fear of illness (8.9%), long-term effects (6.5%), mistrust in the vaccine (6.3%), and needing more information (4.5%). Vaccine-hesitant participants were more likely to be unvaccinated (adjusted odds ratio=2.3, 95% confidence interval 1.25-4.14) after adjusting for age, education, employment, insurance, health status, and income.

Conclusion

Vaccine hesitancy may be improved by directly addressing fear of illness resulting from vaccines and improving clarity in the vaccine development and approval process to improve uptake among black adults.

Community stressors (violence, victimization, and neighborhood disorder) with cardiometabolic outcomes in urban Jamaica

Background

Despite limited data on neighborhood factors and health risk in Caribbean populations, previous analyses from Jamaica have shown that neighborhood and home disorder were associated with lower physical activity and higher cumulative biological risk among women, while poorer neighborhood infrastructure was associated with higher overweight/obesity among men.

Design

Cross-sectional survey design.

Objectives

In this study, we explored whether community stressors, as measured by community violence, victimization and neighborhood disorder scores, were associated with cardiometabolic outcomes (obesity, diabetes, hypertension and high cholesterol) in urban Jamaican communities. Sex-specific Poisson regression models were used to estimate prevalence ratios (PR) for these associations, adjusting for age, education, diet, physical activity and smoking.

Participants

Of the 849 participants (M = 282; F = 567), mean age was 48 ± 18.5 years and most had at least a high school education. Men were more likely to be current smokers (29.4 vs. 10.6%) and adequately physically active (53.2 vs. 42.0%); more women were obese (46.0 vs. 19.0%), more likely to have hypertension (52.9 vs. 45.4%) and had high cholesterol (34.2 vs. 21.6%) (all p < 0.05).

Results

We observed significant associations only for those in the middle tertile of neighborhood disorder with prevalence of higher cholesterol [PR:1.72 (1.20 to 2.47)] in women and lower prevalence of obesity [PR:0.24 (0.10 to 0.53)] in men.

Conclusion

Results suggest that higher, but not the highest level of neighborhood disorder was associated with higher cholesterol levels in women and lower obesity in men. Future work will explore additional approaches to measuring neighborhood characteristics in Jamaica and the mechanisms that may underlie any relationships that are identified.

Design of the think PHRESH longitudinal cohort study: Neighborhood disadvantage, cognitive aging, and alzheimer's disease risk in disinvested, black neighborhoods

BACKGROUND

Black Americans have disproportionately higher rates and earlier onset of Alzheimer's disease and related dementias (ADRD) relative to White Americans. We currently lack a comprehensive understanding of how the lived experience and broader societal factors, including cumulative exposure to structural racism and the mechanisms underlying the risks, may contribute to elevated ADRD risk in Black Americans.

METHODS

The Think PHRESH study builds on existing, community-based research infrastructure, from the ongoing Pittsburgh Hill/Homewood Research on Neighborhood Change and Health (PHRESH) studies, to examine the contributions of dynamic neighborhood socioeconomic conditions across the lifecourse to cognitive outcomes in mid- and late-life adults living in two historically disinvested, predominantly Black communities (anticipated n = 1133). This longitudinal, mixed-methods study rests on the premise that neighborhood racial segregation and subsequent disinvestment contributes to poor cognitive outcomes via factors including (a) low access to educational opportunities and (b) high exposure to race- and socioeconomically-relevant stressors, such as discrimination, trauma, and adverse childhood events. In turn, these cumulative exposures foster psychological vigilance in residents, leading to cardiometabolic dysregulation and sleep disruption, which may mediate associations between neighborhood disadvantage and ADRD risk. This premise recognizes the importance of potential protective factors that may promote cognitive health, including neighborhood social cohesion, safety, and satisfaction. The proposed study will leverage our existing longitudinal data on risk/protective factors and biobehavioral mediators and will include: (1) up to three waves of cognitive assessments in participants ages 50 years + and one assessment in participants ages 35-49 years; clinical adjudication of ADRD will be completed in participants who are 50+, (2) extensive surveys of risk and protective factors, (3) two assessments of blood pressure and objectively measured sleep, (4) a comprehensive assessment of life and residential history; and (5) two rounds of in-depth qualitative interviews to reveal lifecourse opportunities and barriers experienced by Black Americans in achieving optimal cognitive health in late life.

DISCUSSION

Understanding how structural racism has influenced the lived experience of Black Americans, including dynamic changes in neighborhood conditions over time, is critical to inform multi-level intervention and policy efforts to reduce pervasive racial and socioeconomic disparities in ADRD.

Examining Real-World Therapy Practice of Cognitive Screening and Assessment in Post-Acute Care

OBJECTIVES

Routine implementation of cognitive screening and assessment by therapy providers in post-acute settings may promote improved care coordination. This study examined the frequency of cognitive screening and assessment documentation across post-acute settings, as well as its relationship with contextual factors and outcomes.

DESIGN

Cross-sectional observational study using Medicare claims and electronic health record data from 1 large health system.

SETTING AND PARTICIPANTS

Older adults admitted to post-acute care after an acute hospitalization.

METHODS

Descriptive analysis examined documentation of cognitive screening and assessment. Logistic and hierarchical linear regression evaluated the relationship among patient factors, cognitive screening and assessment, and patient outcomes.

RESULTS

The most common admission diagnoses for the final sample (n=2535) were total hip or knee joint replacement (41.7%) and stroke (15.3%). Following acute hospitalization, patients were discharged to inpatient rehabilitation (22.6%), skilled nursing (9.3%), or home health (68.1%). During the post-acute care stay, 38% of patients had documentation of cognitive screening by any therapy discipline. Patterns of documentation varied across disciplines and post-acute settings. Documentation of standardized cognitive assessments was limited, occurring for less than 2% of patients. Admission for stroke was associated with significantly higher odds of cognitive screening or assessment [odds ratio (OR) 2.07, 95% CI 1.13, 3.82] compared to patients with other diagnoses. There was no significant relationship between documentation of cognitive screening or assessment and 30-day readmissions (OR 0.81, 95% CI 0.53, 1.28).

CONCLUSION AND IMPLICATIONS

The key finding was inconsistent documentation of cognitive screening and assessment across disciplines and post-acute settings, which could be in part due to variation in electronic health record platforms. Future work can expand on these results to understand the degree to which contextual factors facilitate or inhibit routine delivery and documentation of cognitive screening and assessment. Findings can support implementation of standardized data elements to lead to improved care coordination and outcomes.

A Comprehensive, Community-Based Coalition to Address Racial Disparities in Chronic Disease: REACH in Allegheny County, Pennsylvania

BACKGROUND

Funded by the Centers for Disease Control and Prevention Racial and Ethnic Approaches to Community Health Initiative, Live Well Allegheny: Lifting Wellness for African Americans (LWA) in Allegheny County, Pennsylvania, aims to enhance health equity by addressing chronic disease in six African American communities via three key strategies: nutrition, physical activity, and community-clinical linkages.

OBJECTIVES

This manuscript describes the coalition's partnership dynamics and evaluation methods with a focus on nutrition strategies.

METHODS

We have a network of committed partners implementing the strategies and we are evaluating our efforts using community asset mapping, county population-based survey data, qualitative process interviews, focus groups, and program performance measures.

RESULTS

The LWA coalition is the culmination of years of partnership building, which allows for more targeted activities related to health equity in the region. Thus far, the LWA coalition is thriving. The network of committed and talented partners in the nutrition strategy (healthy nutrition standards, food systems, and breastfeeding) reached 22 sites and more than 46,000 people during the first 2 years of the project. Process interviews conducted as part of the evaluation identified challenges and successes of implementation, and development of the coalition.

CONCLUSIONS

This comprehensive evaluation approach supports formative processes, evaluation metrics, and prolonged sustainability plans of this community-based coalition.

Impact of COVID-19 on a Community Health Coalition and Its Residents in Allegheny County, Pennsylvania: Insights Into Adaptation From Focus Groups and Evaluation Reports

Live Well Allegheny: Lifting Wellness for African Americans (LWA2) is a coalition in Allegheny County, Pennsylvania, funded by the Centers for Disease Control and Prevention’s (CDC) Racial and Ethnic Approaches to Community Health (REACH) initiative. LWA2 consists of partner organizations addressing chronic disease prevention in six Black communities through nutrition, physical activity, and community–clinical linkage strategies. This analysis focuses on qualitative data exploring the influence of COVID-19 on coalition functioning and communities. We conducted focus groups with residents in REACH communities and collected evaluation reports from partner organizations. Three focus groups assessed awareness of and participation in the REACH initiative, feedback, and the impact of COVID-19 when applicable. An additional focus group included questions related to flu vaccine messaging and the COVID-19 vaccine. These data sources provided insight regarding how COVID-19 affected planned tasks. Evaluation team members analyzed focus groups and collated summaries as part of a larger comprehensive evaluation. Partner organizations experienced an increase in food stamp applications, delays in opening farmers’ markets, a shift to virtual preventive health programs, canceled in-person events, and programmatic interruptions that shifted long-term goals. Community resident concerns included difficulty accessing public transportation, decreased physical activity, fear of in-person interactions, and increased wait times for mental health services. Coalition members developed methods to continue functioning and sustaining program activities. Residents were able to engage differently with chronic illness prevention techniques. Reports from the ongoing analysis will be used to adapt coalition functioning.

Instituting Racial Equity: The Allegheny County Racial and Ethnic Approaches to Community Health Initiative

INTRODUCTION

In 2018, The Live Well Allegheny: Lifting Wellness for African Americans (LWA2) Initiative was developed to support six priority, Black communities in Allegheny County, Pennsylvania to address health equity in chronic disease. The LWA2 coalition members participated in ongoing anti-racism and racial equity sessions with a nationally recognized anti-racist facilitation team. The sessions included a 2-days experience in January 2020 along with follow up meetings throughout 2020.

METHODS

Surveys were administered to understand their perceptions related to anti-racism and oppression and subsequent actions as a result of the sessions. Additionally, we conducted nine in-depth interviews with organizational partners (January -May 2020) to evaluate the overall effectiveness of the coalition and inform future activities.

RESULTS

Ten participants completed the post session surveys. Seven out of 10 survey respondents felt they had a good understanding of how oppression (racism, sexism, capitalism) influenced their life and work. However, the majority indicated needing the tools to implement anti-racist strategies in their work. The in-depth interviews with organizational partners revealed that racial equity was of concern to all partners but there was variability in intentionality around racial equity as a core element of each organization's mission, goals and subsequent actions.

DISCUSSION

As a result of the interviews, coalition members developed a racial equity statement and theory of change for implementation in the coalition work and within individual organizations along with a plan for implementing an equity audit of the coalition. Coalitions of this kind should be intentional about implementing continuous strategies related to anti-racism for structural changes toward achieving racial equity in their overall work.

Stress during pregnancy: An ecological momentary assessment of stressors among Black and White women with implications for maternal health

BACKGROUND

Stress can lead to adverse physiological and psychological outcomes. Therefore, understanding stress during pregnancy provides insight into racial disparities in maternal health, particularly Black maternal health.

OBJECTIVES

This study aimed to describe (1) daily exposure to self-reported stress levels during pregnancy, and (2) sources of stress among participants that identified as Black or White using data collected via ecological momentary assessment.

METHODS

We leveraged survey data from the Postpartum Mothers Mobile Study, a prospective longitudinal study using ecological momentary assessment data collection methods to describe patterns of stress during pregnancy. This article is descriptive and documents patterns of self-reported stress levels and sources of stress. Frequencies and percentages of stress responses were computed to describe these patterns.

RESULTS

The sample (n = 296) was 27% Black (n = 78) and 63% White (n = 184). Results were based on at least one measurement of that stress level during pregnancy. A similar number of Black and White participants reported no stress during pregnancy. White (85%-95%) and Black (60%-70%) participants reported low to moderate levels of stress. Black participants (38%) and White participants (35%) reported experiencing high stress. Black and White participants reported similar sources of stress: stress from a partner, too many things to do, a baby or other children, and financial concerns. White participants reported work as a top stressor, and Black participants reported financial issues as a top source of stress.

CONCLUSION

This study provides insight into daily exposure to stress that has implications for maternal health. We described patterns of self-reported stress and sources of stress among Black and White participants. The daily exposures to stress reported by this sample exist within a context of root causes of structural inequities in education, health care, income, wealth, and housing that must be addressed to achieve maternal health equity.

Social Determinants of Health, Race, and Diabetes Population Health Improvement: Black/African Americans as a Population Exemplar

PURPOSE OF REVIEW

To summarize evidence of impact of social determinants of health (SDOH) on diabetes risk, morbidity, and mortality and to illustrate this impact in a population context.

RECENT FINDINGS

Key findings from the American Diabetes Association's scientific review of five SDOH domains (socioeconomic status, neighborhood and physical environment, food environment, health care, social context) are highlighted. Population-based data on Black/African American adults illustrate persisting diabetes disparities and inequities in the SDOH conditions in which this population is born, grows, lives, and ages, with historical contributors. SDOH recommendations from US national committees largely address a health sector response, including health professional education, SDOH measurement, and patient referral to services for social needs. Fewer recommendations address solutions for systemic racism and socioeconomic discrimination as root causes. SDOH are systemic, population-based, cyclical, and intergenerational, requiring extension beyond health care solutions to multi-sector and multi-policy approaches to achieve future population health improvement.

Longitudinal Associations Between Changes in Cigarette Smoking and Alcohol Use, Eating Behavior, Perceived Stress, and Self-Rated Health in a Cohort of Low-Income Black Adults

BACKGROUND

Black adults in the U.S. experience significant health disparities related to tobacco use and obesity. Conducting observational studies of the associations between smoking and other health behaviors and indicators among Black adults may contribute to the development of tailored interventions.

PURPOSE

We examined associations between change in cigarette smoking and alcohol use, body mass index, eating behavior, perceived stress, and self-rated health in a cohort of Black adults who resided in low-income urban neighborhoods and participated in an ongoing longitudinal study.

METHODS

Interviews were conducted in 2011, 2014, and 2018; participants (N = 904) provided at least two waves of data. We fit linear and logistic mixed-effects models to evaluate how changes in smoking status from the previous wave to the subsequent wave were related to each outcome at that subsequent wave.

RESULTS

Compared to repeated smoking (smoking at previous and subsequent wave), repeated nonsmoking (nonsmoking at previous and subsequent wave) was associated with greater likelihood of recent dieting (OR = 1.59, 95% CI [1.13, 2.23], p = .007) and future intention (OR = 2.19, 95% CI [1.61, 2.98], p < .001) and self-efficacy (OR = 1.64, 95% CI [1.21, 2.23], p = .002) to eat low calorie foods, and greater odds of excellent or very good self-rated health (OR = 2.47, 95% CI [1.53, 3.99], p < .001). Transitioning from smoking to nonsmoking was associated with greater self-efficacy to eat low calorie foods (OR = 1.89, 95% CI [1.1, 3.26], p = .021), and lower perceived stress (β = -0.69, 95% CI [-1.34, -0.05], p = .036).

CONCLUSIONS

We found significant longitudinal associations between smoking behavior and eating behavior, perceived stress, and self-rated health. These findings have implications for the development of multiple behavior change programs and community-level interventions and policies.

Sleep Disturbances, Changes in Sleep, and Cognitive Function in Low-Income African Americans

BACKGROUND

Sleep problems may contribute to the disproportionate burden of Alzheimer's disease and related dementias (ADRD) among African Americans (AAs).

OBJECTIVE

To examine the role of sleep problems in contributing to cognitive function and clinically adjudicated cognitive impairment in a predominantly AA sample.

METHODS

This study (n = 216, 78.8% female; mean age = 67.7 years) examined associations between 1) the level (i.e., measured in 2018) and 2) change over time (from 2013 to 2018; n = 168) in actigraphy-assessed sleep with domain-specific cognitive function and clinically adjudicated cognitive impairment (2018) in a community-dwelling, predominantly AA (96.9%) sample. A comprehensive cognitive battery assessed global cognitive function (3MS) and domain-specific cognitive function (attention, visuo-spatial ability, language, delayed recall, immediate recall, and executive function) in 2018. Sleep was measured in 2013 and 2018 via actigraphy.

RESULTS

Higher sleep efficiency and less wakefulness after sleep onset (WASO; measured in 2018) were associated with greater attention, executive function, and visuospatial ability. Increases in sleep efficiency between 2013 and 2018 were associated with better executive function, language, immediate recall, and visuospatial ability, whereas increases in WASO (2013-2018) were associated with poorer attention, executive function, and visuospatial ability. Level or change in sleep duration were not associated with domain-specific cognitive function, nor were any sleep measures associated with clinically adjudicated cognitive impairment.

CONCLUSION

In a predominantly AA sample of older adults, both the level and change (i.e., worsening) of sleep efficiency and WASO were associated with poorer cognitive function. Improving sleep health may support ADRD prevention and reduce health disparities.

Neighborhood Food Environment Associated with Cardiometabolic Health among Predominately Low-income, Urban, Black Women

Objectives

This study sought to: 1) understand how the perceived food environment (availability, accessibility, and affordability) is associated with cardiometabolic health outcomes in predominately low-income Black residents in urban neighborhoods with limited healthy food access; and 2) examine the association of shopping at specific store types with cardiometabolic health outcomes.

Methods

We report on cross-sectional data from 459 individuals participating in the Pittsburgh, PA Hill/Homewood Research on Neighborhoods and Health (PHRESH) study. Mean participant age was 60.7 (SD=13.9); 81.7% were female. We used logistic regression to examine associations between three factors (perceived fruit and vegetable availability, quality, and price; primary food shopping store characteristics; and frequency of shopping at stores with low or high access to healthy foods) and cardiometabolic and self-rated health.

Results

Adjusting for sociodemographic characteristics, participants with higher perceived fruit and vegetable accessibility (AOR:.47, 95%CI: .28-.79, P=.004) and affordability (AOR:.59, 95%CI: .36-.96, P=.034) had lower odds of high blood pressure. Shopping often (vs rarely) at stores with low access to healthy foods was associated with higher odds of high total cholesterol (AOR:3.52, 95%CI: 1.09-11.40, P=.035). Finally, primary food shopping at a discount grocery (vs full-service supermarket) was associated with lower odds of overweight/obesity (AOR:.51, 95%CI: .26-.99, P=.049).

Conclusions

These results suggest that both perceived accessibility and affordability of healthy foods are associated with reduced cardiometabolic risk factors in this urban, low-income predominantly Black population. Additionally, discount grocery stores may be particularly valuable by providing access and affordability of healthy foods in this population.

A Closer Look at Racial Differences in Diabetes Outcomes Among a Community Sample: Diabetes Distress, Self-care, and HbA1c

OBJECTIVE

Approximately 34 million people in the U.S. have diabetes. With this illness come substantial changes to psychological and physical health. However, type 2 diabetes disproportionately affects non-Hispanic Black compared with non-Hispanic White populations. The purpose of this study was to examine racial differences in psychological, behavioral, and physical health over time among individuals recently diagnosed with type 2 diabetes.

RESEARCH DESIGN AND METHODS

Data were collected from a community sample of 193 adults recently diagnosed with type 2 diabetes (44% female; 45% Black). Measures of distress, self-care behaviors, and HbA1c were taken at an initial interview (time 1) and 6 months later (time 2). Individuals wore an Actical accelerometer to assess physical activity and participated in three 24-h dietary recall interviews to assess dietary intake within 2 weeks of the initial interview.

RESULTS

From time 1 to time 2, Black women showed the highest increase in depressive symptoms. There was a greater increase in regimen and physician distress among White compared with Black participants. White men and Black women reported a decline in medication adherence over time. There were no racial differences in changes in physical activity across 6 months. However, Black individuals had higher overall calorie consumption with greater protein, saturated fat, and cholesterol intake than White individuals. There were no race or sex differences in changes in glycemic stability.

CONCLUSIONS

Initial adjustment to a diagnosis of type 2 diabetes differentially influences Black and White men and women in terms of depressive symptoms, diabetes distress, and self-care.

Trends in Stress Throughout Pregnancy and Postpartum Period During the COVID-19 Pandemic: Longitudinal Study Using Ecological Momentary Assessment and Data From the Postpartum Mothers Mobile Study

BACKGROUND

Stress is associated with adverse birth and postpartum health outcomes. Few studies have longitudinally explored racial differences in maternal stress in a birthing population in the United States during the ongoing COVID-19 pandemic.

OBJECTIVE

This study aimed to do the following: (1) assess changes in reported stress before, during, and after initial emergency declarations (eg, stay-at-home orders) were in place due to the COVID-19 pandemic, and (2) assess Black-White differences in reported stress in a pregnant and postpartum population from Southwestern Pennsylvania.

METHODS

We leveraged data from the ongoing Postpartum Mothers Mobile Study (PMOMS), which surveys participants in real time throughout the pregnancy and postpartum periods via ecological momentary assessment (EMA) and smartphone technology. We analyzed data from a subset of PMOMS participants (n=85) who were either Black or White, and who submitted EMA responses regarding stress between November 1, 2019, and August 31, 2020, the time frame of this study. We divided data into four phases based on significant events during the COVID-19 pandemic: "pre" phase (baseline), "early" phase (first case of COVID-19 reported in United States), "during" phase (stay-at-home orders), and "post" phase (stay-at-home orders eased). We assessed mean stress levels at each phase using linear mixed-effects models and post hoc contrasts based on the models.

RESULTS

Overall mean stress (0=not at all to 4=a lot) during the pre phase was 0.8 for Black and White participants (range for Black participants: 0-3.9; range for White participants: 0-2.8). There was an increase of 0.3 points (t5649=5.2, P<.001) in the during phase as compared with the pre phase, and an increase of 0.2 points (t5649=3.1, P=.002) in the post phase compared with the pre phase (n=85). No difference was found between Black and White participants in the change in mean stress from the pre phase to the during phase (overall change predicted for the regression coefficient=-0.02, P=.87). There was a significant difference between Black and White participants in the change in mean stress from the during phase to the post phase (overall change predicted for the regression coefficient=0.4, P<.001).

CONCLUSIONS

There was an overall increase in mean stress levels in this subset of pregnant and postpartum participants during the same time as the emergency declarations/stay-at-home orders in the United States. Compared to baseline, mean stress levels remained elevated when stay-at-home orders eased. We found no significant difference in the mean stress levels by race. Given that stress is associated with adverse birth outcomes and postpartum health, stress induced by the ongoing COVID-19 pandemic may have adverse implications for birthing populations in the United States.

Links of communal coping to relationship and psychological health in type 2 diabetes: actor-partner interdependence models involving role, sex, and race

BACKGROUND

Communal coping is one person's appraisal of a stressor as shared and collaboration with a partner to manage the problem. There is a burgeoning literature demonstrating the link of communal coping to good relationships and health among persons with chronic disease.

PURPOSE

We examined links of communal coping to relationship and psychological functioning among couples in which one person was recently diagnosed with type 2 diabetes. We distinguished effects of own communal coping from partner communal coping on both patient and spouse relationship and psychological functioning, as well as whether communal coping effects were moderated by role (patient, spouse), sex (male, female), and race (White, Black).

METHODS

Participants were 200 couples in which one person had been diagnosed with type 2 diabetes (46% Black, 45% female) within the last 5 years. Couples completed an in-person interview, participated in a discussion to address diabetes-related problems, and completed a postdiscussion questionnaire.

RESULTS

Own communal coping and partner communal coping were related to good relationship and psychological functioning. Interactions with role, sex, and race suggested: (i) partner communal coping is more beneficial for patients than spouses; (ii) own communal coping is more beneficial for men, whereas partner communal coping is more beneficial for women; and (iii) White patients and Black spouses benefit more from own communal coping than Black patients and White spouses.

CONCLUSION

These findings demonstrate the benefits of communal coping across an array of self-report and observed indices, but suggest there are differential benefits across role, sex, and race.

Improvements in Neighborhood Socioeconomic Conditions May Improve Resident Diet

Neighborhood socioeconomic conditions (NSECs) are associated with resident diet, but most research has been cross-sectional. We capitalized on a natural experiment in Pittsburgh, Pennsylvania, in which 1 neighborhood experienced substantial investments and a sociodemographically similar neighborhood that did not, to examine pathways from neighborhood investments to changed NSECs and changed dietary behavior. We examined differences between renters and homeowners. Data were from a random sample of households (n = 831) in each of these low-income Pittsburgh neighborhoods that were surveyed in 2011 and 2014. Structural equation modeling tested direct and indirect pathways from neighborhood to resident dietary quality, adjusting for individual-level sociodemographics, with multigroup testing by homeowners versus renters. Neighborhood investments were directly associated with improved dietary quality for renters (β = 0.27, 95% confidence interval (CI): 0.05, 0.50) and homeowners (β = 0.51, 95% CI: 0.10, 0.92). Among renters, investments also were associated with dietary quality through a positive association with commercial prices (β = 0.34, 95% CI: 0.15, 0.54) and a negative association with residential prices (β = -0.30, 95% CI: -0.59, -0.004). Among homeowners, we did not observe any indirect pathways from investments to dietary quality through tested mediators. Investing in neighborhoods may support resident diet through improvements in neighborhood commercial environments for renters, but mechanisms appear to differ for homeowners.

Geographically-explicit Ecological Momentary Assessment (GEMA) Architecture and Components: Lessons Learned from PMOMS

Geographically explicit Ecological Momentary Assessment (GEMA), an extension of Ecological Momentary Assessment (EMA), allows to record time-stamped geographic location information for behavioral data in the every-day environments of study participants. Considering that GEMA studies are continually gaining the attention of researchers and currently there is no single approach in collecting GEMA data, in this paper, we propose and present a GEMA architecture that can be used to conduct any GEMA study based on our experience developing and maintaining the Postpartum Mothers Mobile Study (PMOMS). Our GEMA client-server architecture can be customized to meet the specific requirements of each GEMA study. Key features of our proposed GEMA architecture include: utilization of widely used smartphones to make GEMA studies practical; alleviation of the burden of activities on participants by designing clients (mobile applications) that are very lightweight and servers that are heavyweight in terms of functionality; utilization of at least one positioning sensor to determine EMA contexts marked with locations; and communication through the Internet. We believe that our proposed GEMA architecture, with the illustrated foundation for GEMA studies in our exemplar study (PMOMS), will help researchers from any field conduct GEMA studies efficiently and effectively.

Pharmacist Involvement in Addressing Public Health Priorities and Community Needs: The Allegheny County Racial and Ethnic Approaches to Community Health (REACH) Project

Community–clinical linkages are connections between community and clinical sectors to improve population health, and community-based pharmacists are well positioned to implement this strategy. We implemented a novel approach to community–clinical linkages in African American communities in which community-based pharmacists implement screenings for chronic disease and social determinants of health, make referrals to clinical and social services, and follow up with patients to support linkage to care in nontraditional health care settings. The community-based pharmacist navigation program works with multisector partners to increase referrals and access to existing health and social service programs. We used a mixed-methods evaluation approach to collect and analyze data on program characteristics and the linkage intervention. From February 2019 to March 2020, 702 African American community members received preventive health screenings, and 508 (72%) were referred to clinical and social services. Pharmacists demonstrated the ability to implement clinical preventive services in nontraditional health care settings and improve access to care through the provision of community–clinical linkages.

A Decade of Drinking: Temporal Trends in Apparent Household Beer Intake and Standard Drink Consumption in the United States

Beer remains the greatest source of per capita alcohol consumption in the United States, and increasing market availability and consumer demand for higher alcohol has meaningful public health consequences. Objectives: To determine whether apparent alcohol intake from beer changed among households over time, we used nationally-representative US Nielsen Consumer Panel purchasing data from 2004 to 2014, and incorporated information on percent alcohol by volume (ABV) to compute the number of standard drinks of alcohol consumed from beer as a result. Methods: We queried external data sources (e.g. official manufacture, consumer beer-related websites) to obtain beer-specific ABVs, merged this information with Nielsen consumer-level data, and calculated the average rate of beer and standard drink consumption per household per year. We used joinpoint regression to estimate annual percentage changes and annual absolute changes in intake over time, with separate piecewise linear segments fit between years if a significant deviation in trend was detected. Results: Higher alcohol content beer consumption increased steadily across the decade, accounting for 9.6% of total intake in 2004 compared to 21.6% of total intake by 2014. Standard drink intake from beer declined sharply post-2011 by 3.04% annually (95% CI: -5.93, -0.06) or by 4.52 standard drinks (95% CI: -8.69, -0.35) yearly - coinciding with several beer industry transitions, market share fluctuations, and consumer preference changes for beer occurring around that time. Conclusions: Despite consistent increases in higher alcohol content beer intake across the decade, households do not appear to be consuming more standard drinks of alcohol from beer as a result.Supplemental data for this article is available online at https://doi.org/10.1080/10826084.2021.1928208 .

Ecological momentary assessment of stress, racism and other forms of discrimination during pregnancy using smartphone technology

BACKGROUND

In the United States, there are considerable racial inequities in adverse perinatal outcomes. Exposure to racism, sexism, and other forms of oppression may help explain these inequities.

OBJECTIVES

To describe the application of real-time data collection using ecological momentary assessment (EMA) and smartphone technology to assess exposure to stress, racism, sexism, microaggressions, and other forms of oppression.

METHODS

The Postpartum Mothers Mobile Study (PMOMS) is an ongoing longitudinal cohort study that began recruitment in December 2017. Participants delivering at a hospital in Pittsburgh, PA are recruited by 29 weeks' gestation. Using smartphones and smart scales, participants complete daily surveys related to psychosocial, behavioural, and contextual factors and weigh themselves weekly for approximately 15 months. We provide a preliminary descriptive analysis of EMA self-reported measures of stress, racism, sexism, and microaggressions; and non-EMA measures of stress and major discrimination.

RESULTS

The sample (n = 230) is 63.5% White, 24.8% Black/African American, and 7% Hispanic origin. The most commonly reported item from the Major Discrimination Scale is being unfairly fired (18.1% of the sample). Of those, 31.7% and 17.1% attribute unfair firing to their gender and race, respectively. From the random EMA measures, on average, participants report experiences of racism and sexism at least once daily, in an average 12-hour day over the 4-week period. Black participants indicate about two experiences per day of racism, and White participants indicate more than 1 per day of sexism. Mean stress levels from the EMA measures were similar to the stress measures collected at baseline.

CONCLUSIONS

The methods applied in PMOMS provide real-time data regarding how participants' daily experiences of stress and discrimination influence their lives. Future work will include understanding if and how these EMA measures may relate to already established measures of racism, sexism, and stress; and ultimately understanding associations with perinatal inequities.

Do investments in low-income neighborhoods produce objective change in health-related neighborhood conditions?

This study examined the effect of neighborhood investments on neighborhood walkability, presence of incivilities, and crime in two low-income, primarily African American neighborhoods in Pittsburgh, USA. During the study period, one of the neighborhoods (the intervention neighborhood) received substantially more publicly-funded investments than a demographically matched comparison neighborhood. Comparisons between the neighborhoods showed a significant difference-in-difference for all three outcomes. The intervention neighborhood experienced significantly more change related to improved walkability and decreased incivilities. However, the control neighborhood experienced better crime-related outcomes. Analyses that focused on resident proximity to investments found similar results. This highlights the nuances of neighborhood investment, which is important to consider when thinking about public policy.

Prevalence and correlates of obstructive sleep apnea in urban-dwelling, low-income, predominantly African-American women

STUDY OBJECTIVES

The current study examined the prevalence and correlates of obstructive sleep apnea in a sample of low-income, predominantly African-American women using two waves of data.

METHODS

Participants were adults from two urban neighborhoods who enrolled in the PHRESH Zzz Study (N = 828; Pittsburgh Hill/Homewood Research on Neighborhoods, Sleep, and Health). A subsample who reported never receiving OSA diagnosis completed home sleep apnea testing in 2016 (n = 269, mean age 55.0 years, 79.6% female) and again in 2018 (n = 135). Correlates of OSA tested included demographic and anthropometric variables, health behavior/conditions, psychological distress and general health, smoking status, actigraphy-measured sleep, and neighborhood factors measured at baseline.

RESULTS

18.0% of all 2016 participants reported receiving physician diagnoses of OSA. Among those who completed in-home assessment, 19.3% had AHI ≥15 and 33.8% had AHI ≥5 plus one or more sleep symptoms. Estimates of the prevalence of OSA in all 2016 participants were 33.8%-45.7% based on physician diagnoses and AHI results, depending on the criteria used. Age, gender, BMI, blood pressure, habitual snoring, neighborhood walkability, actigraphy-measured sleep characteristics, and smoking were concurrently associated with OSA in 2016. Changes in AHI categories from 2016 to 2018 were documented.

CONCLUSIONS

Low-income African Americans, including women, are a high-risk group for OSA, but remain under-diagnosed and under-treated. The current findings show a high prevalence of OSA in African-American women and are among the first to demonstrate that both individual and neighborhood factors are implicated in OSA prevalence.

Broken Windows, Broken Zzs: Poor Housing and Neighborhood Conditions Are Associated with Objective Measures of Sleep Health

African Americans and socioeconomically disadvantaged individuals have higher rates of a variety of sleep disturbances, including short sleep duration, poor sleep quality, and fragmented sleep. Such sleep disturbances may contribute to pervasive and widening racial and socioeconomic (SES) disparities in health. A growing body of literature demonstrates that over and above individual-level SES, indicators of neighborhood disadvantage are associated with poor sleep. However, there has been scant investigation of the association between sleep and the most proximal environments, the home and residential block. This is the first study to examine the association between objective and self-reported measures of housing and block conditions and sleep. The sample included 634 adults (mean age = 58.7 years; 95% African American) from two low-income urban neighborhoods. Study participants reported whether they experienced problems with any of seven different housing problems (e.g., broken windows) and rated the overall condition of their home. Trained data collectors rated residential block quality. Seven days of wrist actigraphy were used to measure average sleep duration, efficiency, and wakefulness after sleep onset (WASO), and a sleep diary assessed sleep quality. Multivariate regression analyses were conducted for each sleep outcome with housing or block conditions as predictors in separate models. Participants reporting "fair" or "poor" housing conditions had an adjusted average sleep duration that was 15.4 min shorter than that of participants reporting "good" or "excellent" conditions. Those reporting any home distress had 15.9 min shorter sleep and .19 units lower mean sleep quality as compared with participants who did not report home distress. Poor objectively measured block quality was associated with 14.0 min shorter sleep duration, 1.95% lower sleep efficiency, and 10.7 additional minutes of WASO. Adverse housing and proximal neighborhood conditions are independently associated with poor sleep health. Findings highlight the importance of considering strategies that target upstream determinants of sleep health disparities.

Changes Over Time in Disparities in Health Behaviors and Outcomes by Race in Allegheny County: 2009 to 2015

Racial/ethnic disparities in health behaviors and disease outcomes on the national level have persisted over time despite overall improvements in public health. To better understand the changes over time in racial/ethnic health disparities at the county level, we examined the Allegheny County Health Survey (ACHS) for Pittsburgh, PA and the surrounding area, which was conducted in 2009/2010 and 2015/2016 using random digit dialing of residents aged 18 and older. The prevalence rates and rate ratios at each time period were calculated using survey weights and general linear models. The change in prevalence over time was calculated using race-time interaction terms. The results showed a significant improvement in asthma, stroke, cholesterol, and fair or poor health disparities as well as persistent disparities in diabetes and hypertension after adjustment for socioeconomic factors. The change over time in the prevalence of fair or poor health in black compared to white respondents was significant, with absolute improvement of approximately 5% versus < 1%, respectively (p = 0.01). These findings demonstrate that some disparities improved while others persist, noting the importance of monitoring the changes over time at the local health department level.

Changes in perceptions of neighborhood environment and Cardiometabolic outcomes in two predominantly African American neighborhoods

Background

Perceived neighborhood characteristics, including satisfaction with one’s neighborhood as a place to live, are associated with lower obesity rates and more favorable cardiovascular risk factor profiles. Yet, few studies have evaluated whether changes in perceived neighborhood characteristics over time may be associated with cardiometabolic health indicators.

Methods

Changes in perception of one’s neighborhood (2013–2016) were determined from a cohort of residents who lived in one of two low-income urban neighborhoods. Changes were categorized into the following: improvement vs. no change or worsening over the three-year time-period. Multivariable linear regression was used to measure the association between perceived improvement in each of the neighborhood characteristics with cardiometabolic outcomes (BMI, SBP, DBP, HbA1c, HDL-c) that were assessed in 2016, and compared with those who perceived no change or worsening of neighborhood characteristics. Models were adjusted for age, sex, income, education, marital status, physical function, neighborhood, and years spent in neighborhood. To examine potential sex differences, follow-up models were conducted and stratified by sex.

Results

Among the 622 individuals who remained in the same neighborhood during the time period, 93% were African American, 80% were female, and the mean age was 58 years. In covariate-adjusted models, those who perceived improvement in their neighborhood safety over the time period had a significantly higher BMI (kg/m²) than those who perceived no improvement or worsening (β = 1.5, p = 0.0162); however, perceived improvement in safety was also significantly associated with lower SBP (mmHg) (β = − 3.8, p = 0.0361). When results were stratified by sex, the relationship between improved perceived neighborhood safety and BMI was only evident in females.

Conclusions

These findings suggest that perceived neighborhood characteristics may impact cardiometabolic outcomes (BMI, SBP), but through differing pathways. This highlights the complexity of the associations between neighborhood characteristics and underscores the need for more longitudinal studies to confirm the associations with cardiometabolic health in African American populations.

Food Bank-Based Diabetes Prevention Intervention to Address Food Security, Dietary Intake, and Physical Activity in a Food-Insecure Cohort at High Risk for Diabetes

Purpose and Objectives

Although food insecurity is associated with poor dietary intake and risk of chronic disease, few studies have demonstrated the effectiveness of diabetes prevention interventions delivered through food banks. Food banks serve vulnerable communities. The purpose of this pilot project was to assess the effectiveness of a food bank–delivered intervention aimed at improving food security and reducing risk factors for type 2 diabetes among at-risk clients.

Intervention Approach

We screened adult English- and Spanish-speaking food bank clients for type 2 diabetes risk at 12 community food distribution sites in Alameda County, California. Screening and enrollment for a pilot intervention took place from November 2017 to March 2018. Intervention components were delivered from November 2017 through March 2019. The intervention included monthly diabetes-appropriate food packages, text-based health education, and referrals to health care.

Evaluation Methods

Food bank staff members administered surveys to participants at baseline, 6 months (midpoint), and 12 months (postintervention); participants self-reported all responses. Primary outcomes assessed were food security status, dietary intake, health-related behaviors, and body mass index (BMI). Information on demographic characteristics, food pantry access, health care use, and symptoms of depression was also collected.

Results

We screened 462 food bank clients for eligibility. Of the 299 who were eligible, 244 enrolled; 90.6% were female, 80.1% were Hispanic, and 49.1% had an annual household income less than $20,000. At baseline, 68.8% of participants had low or very low food security. At midpoint, participants had significant improvements in food security status, dietary intake, physical activity, health status, and depression scores. Mean BMI did not change.

Implications for Public Health

This intervention demonstrated that food banks can effectively screen clients at high risk for diabetes and improve household food security and other risk factors for diabetes. Food banks may be an important and strategic partner for health care systems or community-based organizations working to prevent diabetes in food-insecure populations.

Does Large-Scale Neighborhood Reinvestment Work? Effects of Public-Private Real Estate Investment on Local Sales Prices, Rental Prices, and Crime Rates

During the 1990s, the U.S. Department of Housing and Urban Development awarded more than $6 billion in competitive grants called HOPE VI to spur neighborhood redevelopment. We add to HOPE VI research by examining the impacts of a large set of public-private real estate investments, including HOPE VI, made over a 16-year period in a distressed Pittsburgh neighborhood called the Hill District. Specifically, we estimate the effects of the $468 million additional public-private investments that Hill District received compared to a demographically similar neighborhood on sale prices, rental prices, and crime. We find large and statistically significant impacts of the public-private investments on residential sales prices, commercial sales prices, and on rental prices, but only a marginally significant yet meaningful decline in non-violent arrests. For each additional $10 million of public-private investment, we find a 0.95 percent increase in residential sales prices, 2.7 percent increase in commercial sales prices, and 0.55 percent increase in rental prices. Because there was an accumulated difference over 16 years of $468 million in the amount of public-private investment across the two neighborhoods we examine, these percentage increases amount to large changes in real estate prices over that time. Commercial real estate investors and homeowners benefited the most, followed by residential landlords. Our analyses imply cities should anticipate the potential impacts of major neighborhood investment on low-income households, especially unsubsidized renters that most directly experience the brunt of rising rents.

Understanding Pregnancy and Postpartum Health Using Ecological Momentary Assessment and Mobile Technology: Protocol for the Postpartum Mothers Mobile Study

Background

There are significant racial disparities in pregnancy and postpartum health outcomes, including postpartum weight retention and cardiometabolic risk. These racial disparities are a result of a complex interplay between contextual, environmental, behavioral, and psychosocial factors.

Objective

This protocol provides a description of the development and infrastructure for the Postpartum Mothers Mobile Study (PMOMS), designed to better capture women’s daily experiences and exposures from late pregnancy through 1 year postpartum. The primary aims of PMOMS are to understand the contextual, psychosocial, and behavioral factors contributing to racial disparities in postpartum weight and cardiometabolic health, with a focus on the daily experiences of stress and racism, as well as contextual forms of stress (eg, neighborhood stress and structural racism).

Methods

PMOMS is a longitudinal observation study that is ancillary to an existing randomized control trial, GDM² (Comparison of Two Screening Strategies for Gestational Diabetes). PMOMS uses an efficient and cost-effective approach for recruitment by leveraging the infrastructure of GDM², facilitating enrollment of participants while consolidating staff support from both studies. The primary data collection method is ecological momentary assessment (EMA) and through smart technology (ie, smartphones and scales). The development of the study includes: (1) the pilot phase and development of the smartphone app; (2) feedback and further development of the app including selection of key measures; and (3) implementation, recruitment, and retention.

Results

PMOMS aims to recruit 350 participants during pregnancy, to be followed through the first year after delivery. Recruitment and data collection started in December 2017 and are expected to continue through September 2020. Initial results are expected in December 2020. As of early May 2019, PMOMS recruited a total of 305 participants. Key strengths and features of PMOMS have included data collection via smartphone technology to reduce the burden of multiple on-site visits, low attrition rate because of participation in an ongoing trial in which women are already motivated and enrolled, high EMA survey completion and the use of EMA as a unique data collection method to understand daily experiences, and shorter than expected timeframe for enrollment because of the infrastructure of the GDM² trial.

Conclusions

This protocol outlines the development of the PMOMS, one of the first published studies to use an ongoing EMA and mobile technology protocol during pregnancy and throughout 1 year postpartum to understand the health of childbearing populations and enduring racial disparities in postpartum weight and cardiometabolic health. Our findings will contribute to the improvement of data collection methods, particularly the role of EMA in capturing multiple exposures and knowledge in real time. Furthermore, the results of the study will inform future studies investigating weight and cardiometabolic health during pregnancy and the postpartum period, including how social determinants produce population disparities in these outcomes.

Sex, race, and the role of relationships in diabetes health: intersectionality matters

Previous research has seldom used an intersectionality framework to consider how sex and race affect diabetes health, nor has it examined the role of sex and race in the well-established link between romantic relationship quality and health. This study targeted 200 adults with type 2 diabetes (46% Black; 45% female) and examined whether sex, race, and the interaction between sex and race predicted behavioral and psychological health, or moderated the link between relationship quality and health outcomes. Black women reported poorer diabetes self-care and lower self-efficacy compared to other groups. Relationship quality was associated with better self-care, increased self-efficacy, and lower depressive symptoms. The association between relationship quality and medication adherence was stronger for Black women, and the association between relationship quality and self-efficacy was stronger for both Black women and White men. Results suggest that Black women with diabetes experience more health disadvantages than other groups, but some of these disadvantages might be attenuated by supportive romantic relationships.

Household Support for Physical Activity in Adolescent Girls Living in Primarily Low Socioeconomic Status Neighborhoods

The purpose of this study was to examine the association between perception of household support and physical activity levels of adolescent girls living in primarily low socioeconomic status (SES) neighborhoods. The sample consisted of thirty-six adolescent girls (N=36; 60% non-Hispanic Black; mean age of 14.6 ± 1.3 [mean ± sd]; median body mass index (BMI) percentile of 90.5 [58.5, 97.0]) living in primarily low socioeconomic status (SES) neighborhoods. Trained researchers measured participants' height and weight, and administered questionnaires to assess perception of household support for physical activity and minutes per day participating in moderate-to-vigorous physical activity (MVPA) (3-Day Physical Activity Recall). Pearson's correlation, controlling for race, age, and BMI, was used to evaluate the association between perception of household support and adolescents' MVPA levels. There were no significant associations between measures of the perception of household support for physical activity and adolescents' MVPA levels. There were significant negative associations between total adult household support for physical activity (r=-0.51; p<.01) with BMI and the support provided by the closest adult in the household (r=-0.55; p<.01) with BMI. These data suggest that support for physical activity in the household for adolescents with higher BMI's may be warranted.

Experiences of Community Doulas Working with Low-Income, African American Mothers

Purpose: The aim of this study was to learn from doulas the components of their services that might best serve low-income, African American (AA) women and to show the significance of doulas in helping these women have healthy, positive, birth experiences.

Methods: Ten doulas were recruited from a local community doula program and through word-of-mouth referrals from participants and completed in-depth interviews. Interviews were transcribed verbatim and analyzed using Atlas.ti software to identify emerging themes. Thematic saturation was achieved in interviews.

Results: Several themes emerged from the interviews including: (1) The influence of similarities of race, culture, and lived experience on doula care; (2) How doulas often provide birthing persons with support and resources beyond birth; and (3) How doulas recognize the institutional biases that exist in the health care system and try to mediate their effect on birthing persons.

Conclusions: These themes highlight how doulas can support birthing persons to mitigate the negative effects of social determinants of health, specifically racism and classism, and highlight potential avenues for doulas to consider when working with birthing persons who have low income and are AA.

Evaluation of a Mobile Farmer's Market Aimed at Increasing Fruit and Vegetable Consumption in Food Deserts: A Pilot Study to Determine Evaluation Feasibility

Purpose: In November 2015, Greater Pittsburgh Community Food Bank implemented a pilot phase of the Green Grocer mobile market, a program aimed at improving access to locally sourced fresh foods in low-resource neighborhoods. We conducted an evaluation of this pilot phase. Methods: We conducted baseline surveys of residents in six neighborhoods that received Green Grocer in the pilot phase to understand the food environment, including perceptions of fresh food availability, and another survey of Green Grocer consumers to evaluate their experiences and satisfaction. We measured respondent intake of fruit and vegetable in the terms of days per week and servings per day. We used Poisson regression with cluster-robust standard errors to model the average change in produce consumption pre-post intervention. Results: Residents of select communities observed meaningful improvements in intake. After covariate adjustment, Homewood residents observed an average 13% increase in vegetable intake (days/week) rates post-Green Grocer (p=0.04). Clairton residents also showed marked increases, with an average 20% increase in vegetable intake (servings/day) (p=0.049). After 6 months, declines in produce purchase from discount stores and supercenters were observed alongside increases in procurement from Green Grocer, farmer's markets, gardens, and other sources. Conclusion: Our preliminary work provides support that this mobile market serving under-resourced areas was valued by consumers and showed increases in vegetable consumption in several neighborhoods. When scaled-up, this program had the potential to reduce geographically-based food and health disparities.

Characterizing a Sample of Chinese Patients With Type 2 Diabetes and Selected Health Outcomes

Purpose

The purpose of the study is to describe the characteristics and selected health outcomes of a sample of Chinese patients with type 2 diabetes (T2DM) and to examine gender differences based on social cognitive theory. There is limited study in theory-driven research conducted in China and a lack of evidence in collectively examining the associated factors among Chinese patients with T2DM based on a theory, especially among those living in a suburban area.

Methods

Following a cross-sectional design, data were collected from 207 patients (50.2% women; mean age, 56.1 years) with T2DM from an outpatient clinic in a suburban area of Beijing, China. Participants completed a survey, and clinical values were retrieved from the patients’ medical records.

Results

Of the participants, more than half had suboptimal glycemic control; only a small proportion had recommended levels in performing self-management behaviors. A large proportion had metabolic syndrome and were overweight or obese. Compared with men, women demonstrated poorer health literacy and problem solving, received less social support, and presented with more depressive symptoms.

Conclusion

Glycemic control and self-management were suboptimal in this sample, and a large proportion of the sample was at risk of developing cardiovascular disease. Gender differences exist regarding health literacy, depressive symptoms, problem solving, and social support. Social cognitive theory may provide a lens for addressing factors that are important in improving health outcomes among Chinese patients with T2DM. This evidence will help health care providers to identify pertinent factors through a multifactorial approach, therefore providing tailored care for Chinese patients with T2DM.

Translation of the National Diabetes Prevention Program to Engage Men in Disadvantaged Neighborhoods in New York City: A Description of Power Up for Health

The Diabetes Prevention Program (DPP) landmark randomized trial demonstrated that participants with prediabetes could reduce their risk for type 2 diabetes by 58% if they achieved 5%-7% weight loss through healthy eating and increasing physical activity. The National DPP (NDPP) is a group intervention based on the DPP and has been widely disseminated by the Centers for Disease Control and Prevention (CDC) and many healthcare institutions. While data show that the program is effective in diverse populations, enrollment among men from low-income and minority communities is low. Thus, the study piloted a novel adaptation focused on men living in disadvantaged neighborhoods. The study approach to adaptation and implementation used characteristics of participatory research, including input from an expert panel of African American and Latino leaders, ongoing consultation with an Advisory Panel, and focus groups with members of the target population. Discussions with these groups focused on male perspectives regarding health promotion and barriers and facilitators to participation in health programming for men. There was general agreement when reviewing ongoing pilot program implementation that the adapted program should have male-only groups with male coaches, as the Advisory Panel had originally suggested. The pilot programs were implemented at five New York City Department of Parks and Recreation sites in Harlem, the Bronx, and Brooklyn in 2015-2016.

Power Up for Health: Pilot Study Outcomes of a Diabetes Prevention Program for Men from Disadvantaged Neighborhoods

There is a significant evidence base for the Diabetes Prevention Program, a lifestyle intervention to prevent onset of type 2 diabetes among high-risk individuals; however, translation of this intervention for men has been challenging. This report presents outcomes of the pilot study of an adapted 16-week diabetes prevention program entitled " Power Up for Health." The study goal was to better engage men of color with prediabetes from disadvantaged neighborhoods of New York City. It was implemented at five different recreation centers located in predominantly low-income neighborhoods across New York City. The curriculum was facilitated by male lifestyle coaches only; one group was conducted in Spanish. Primary outcome was weight loss from baseline to 16 weeks. Other measures included lifestyle activities, depressive symptoms, and self-reported health status. Men ( N = 47) were screened by telephone. Of the 29 eligible men who began the program, 25 attended at least 4 sessions (52% non-Latino Black, 32% Latino, mean age 51.7 ± SD 9.9 years, mean body mass index 35 ± SD 6.9 kg/m2). End of program outcomes ( n = 23) varied by site and included a mean weight loss of 3.8% (9.7 lbs); 3 of the 5 sites had a mean weight loss of 5.6%, meeting the national goal of 5%-7%. Men ( n = 23) attended a mean of 11.6 of 16 sessions. Improvement in depressive symptoms, healthy eating and exercise, and health status were also seen. While recruitment was challenging with many lessons learned, the adapted men's diabetes prevention program shows promise of success for participants and their coaches.

Power Up for Health-Participants' Perspectives on an Adaptation of the National Diabetes Prevention Program to Engage Men

The National Diabetes Prevention Program (NDPP) has been effectively translated to various community and clinical settings; however, regardless of setting, enrollment among men and lower-income populations is low. This study presents participant perspectives on Power Up for Health, a novel NDPP pilot adaption for men residing in low-income communities in New York City. We conducted nine interviews and one focus group with seven participants after the program ended. Interview and focus group participants had positive perceptions of the program and described the all-male aspect of the program and its reliance on male coaches as major strengths. Men felt the all-male adaptation allowed for more open, in-depth conversations on eating habits, weight loss, body image, and masculinity. Participants also reported increased knowledge and changes to their dietary and physical activity habits. Recommendations for improving the program included making the sessions more interactive by, for example, adding exercise or healthy cooking demonstrations. Overall, findings from the pilot suggest this NDPP adaptation was acceptable to men and facilitated behavior change and unique discussions that would likely not have occurred in a mixed-gender NDPP implementation.

African Americans in Standard Behavioral Treatment for Obesity, 2001-2015: What Have We Learned?

African Americans (AAs) bear a disproportionate burden of the obesity epidemic, yet have historically been underrepresented in weight loss research. We conducted a narrative review of large ( N > 75) randomized prospective clinical trials of standard behavioral treatment for weight loss that reported results in the past 15 years (2001-2015) to (a) determine the rates of inclusion and reported results for AAs and (b) further identify strategies that may result in improved outcomes. Of the 23 trials reviewed, 69.6% of the studies met or exceeded population estimates for AAs in the United States. However, only 10 reported outcomes and/or considered race in the analytic approach. At 6 months, AA participants consistently lost less weight than White participants. The use of culturally tailored intervention materials and monthly personal telephone calls were reported as factors that may have enhanced treatment response. Future behavioral weight loss trials should also increase reporting of outcomes by race.

Innovative strategies to improve diabetes outcomes in disadvantaged populations

Diabetes disproportionately affects disadvantaged populations. Eighty percent of deaths directly caused by diabetes occurred in low- and middle-income countries. In high-income countries, there are marked disparities in diabetes control among racial/ethnic minorities and those with low socio-economic status. Innovative, effective and cost-effective strategies are needed to improve diabetes outcomes in these populations. Technological advances, peer educators and community health workers have expanded methodologies to reach, educate and monitor individuals with diabetes. In the present manuscript we review the outcomes of these strategies, and describe the barriers to and facilitators of these approaches for improving diabetes outcomes.

Residential environment and breast cancer incidence and mortality: a systematic review and meta-analysis

BACKGROUND

Factors beyond the individual level such as those characterizing the residential environment may be important to breast cancer outcomes. We provide a systematic review and results of meta-analysis of the published empirical literature on the associations between breast cancer risk and mortality and features of the residential environment.

METHODS

Using PRISMA guidelines, we searched four electronic databases and manually searched the references of selected articles for studies that were published before June 2013. We selected English language articles that presented data on adult breast cancer incidence or mortality in relation to at least one area-based residential (ABR) independent variable.

RESULTS

We reviewed 31 eligible studies, and observed variations in ABR construct definition and measurement, study design, and analytic approach. The most common ABR measures were indicators of socioeconomic status (SES) (e.g., income, education, summary measures of several SES indicators or composite SES). We observed positive associations between breast cancer incidence and urbanization (Pooled RR for urban vs. rural: 1.09. 95% CI: 1.01, 1.19), ABR income (Pooled RR for highest vs. lowest ABR income: 1.17, 95% CI: 1.15, 1.19) and ABR composite SES (Pooled RR for highest vs. lowest ABR composite SES: 1.25, 95% CI: 1.08, 1.44). We did not observe consistent associations between any ABR measures and breast cancer mortality.

CONCLUSIONS

The findings suggest modest positive associations between urbanization and residential area socioeconomic environment and breast cancer incidence. Further studies should address conceptual and methodological gaps in the current publications to enable inference regarding the influence of the residential environment on breast cancer.

Reducing sugar-sweetened beverage consumption by providing caloric information: how Black adolescents alter their purchases and whether the effects persist

OBJECTIVES

We examined the ways in which adolescents altered the type and size of their purchases of sugar-sweetened beverages (SSBs), together with whether the effects persisted after removing caloric information signs in stores.

METHODS

We used a case-crossover design with 6 stores located in low-income Black neighborhoods in Baltimore, Maryland, from 2012 to 2013. The intervention used 1 of 4 randomly posted signs with caloric information: absolute calories, number of teaspoons of sugar, and number of minutes of running or miles of walking necessary to burn off a beverage. We collected data for 4516 purchases by Black adolescents, including both baseline and postintervention periods with no signs posted.

RESULTS

We found that providing caloric information significantly reduced the number of total beverage calories purchased, the likelihood of buying an SSB, and the likelihood of buying an SSB greater than 16 ounces (P < .05). After removing the signs, the quantity, volume, and number of calories from SSB purchases remained lower than baseline (P < .05).

CONCLUSIONS

Providing caloric information was associated with purchasing a smaller SSB, switching to a beverage with no calories, or opting to not purchase a beverage; there was a persistent effect on reducing SSB purchases after signs were removed.

Social epidemiology of diabetes and associated conditions

Research focusing on the social determinants of diabetes has focused on individual-level factors such as health behaviors, socioeconomic status, and depression. Fewer studies that incorporate a broader consideration of the multiple contexts or organizational levels (eg, family, health care setting, neighborhood) within which individuals are embedded exist in the mainstream diabetes literature. Such an approach would enhance our understanding of this complex disease, and thus, future avenues of research should consider the following: (1) a life-course approach, which examines the influence of early life exposures on the development of diabetes; (2) aiming to understand the biological mechanisms of social determinants of diabetes; and (3) implementing interventions on multiple levels. Integrating this multilevel and life-course approach will require transdisciplinary science that brings together highly specialized expertise from multiple disciplines. Broadening the study of social determinants is a necessary step toward improving the prevention and treatment of type 2 diabetes.

Physical environment may modify the association between depressive symptoms and change in waist circumference: the multi-ethnic study of atherosclerosis

BACKGROUND

Although the bidirectional association between depressive symptoms and adiposity has been recognized, the contribution of neighborhood factors to this relationship has not been assessed.

OBJECTIVE

This study evaluates whether physical and social neighborhood environments modify the bidirectional relationship between depressive symptoms and adiposity (measured by waist circumference and body mass index).

METHODS

Using data on 5,122 men and women (ages 45 to 84 years) from the Multi-Ethnic Study of Atherosclerosis (MESA) we investigated whether neighborhood physical (i.e., walking environment and availability of healthy food) and social (i.e., safety, aesthetics, and social coherence) environments modified the association between the following: (1) baseline elevated depressive symptoms (Center for Epidemiologic Study Depression Scale score ≥ 16) and change in adiposity (as measured by waist circumference and body mass index) and (2) baseline overweight/obesity (waist circumference > 102 cm for men and >88 cm for women, or body mass index ≥ 25 kg/m(2)) and change in depressive symptoms using multilevel models. Neighborhood-level factors were obtained from the MESA Neighborhood Study.

RESULTS

A greater increase in waist circumference in participants with vs without elevated depressive symptoms was observed in those living in poorly-rated physical environments but not in those living in better-rated environments (interaction p = 0.045). No associations were observed with body mass index. Baseline overweight/obesity was not associated with change in depressive symptoms and there was no modification by neighborhood-level factors.

CONCLUSIONS

Elevated depressive symptoms were associated with greater increase in waist circumference among individuals living in poorly-rated physical environments than in those in better-rated physical environments. No association was found between overweight/obesity and change in depressive symptoms.

Adolescent obesity, change in weight status, and hypertension: racial/ethnic variations

We sought to determine whether change in weight status between adolescence and young adulthood was associated with the risk of developing hypertension among adolescents and whether sex and racial/ethnic group differences existed in the National Longitudinal Study of Adolescent Health. The sample was restricted to participants who self-identified as black, Hispanic, or white non-Hispanic (n=8543). Height and weight were measured in adolescence (mean 16 years) and again in adulthood (mean 29 years). We categorized the weight of participants into 4 groups: stayed normal weight; gained weight (normal weight in adolescence and obese in adulthood); lost weight (overweight/obese in adolescence nonobese in adulthood); and chronically overweight/obese. Hypertension was defined as measured systolic blood pressure of at least 140 mm Hg or diastolic blood pressure of at least 90 mm Hg measured in adulthood or use of antihypertensive medications. A higher risk of hypertension was noted for all sex and racial/ethnic groups who became obese in adulthood. Furthermore, those who were chronically overweight/obese were at higher risk of hypertension for all groups, with odds ratios ranging from 2.7 in Hispanic men to 6.5 in Hispanic women. Except for black men, those who lost weight during follow-up had no significant increased risk compared with those who maintained normal weight. Overall, there was an increased risk of hypertension for those who gained weight in adulthood and among those who remained obese from adolescence to young adulthood. These data give further evidence for prevention strategies that begin earlier in life to reduce or delay the onset of chronic disease in young adults.
