Exploring differences in perceptions of gentrification, neighborhood satisfaction, social cohesion, and health among residents of two predominantly African American Pittsburgh neighborhoods (n = 60).

BACKGROUND: Gentrification often leads to changes in the social and physical environment of neighborhoods, which social capital theory has found are connected to aspects of resident health and wellbeing. A growing body of literature has explored the impact of gentrification on health and wellbeing of residents. The goal of this study is to qualitatively explore the ways in which gentrification may have impacted perceptions of neighborhood satisfaction, social cohesion, and health of neighborhood residents (n = 60) from two predominantly Black neighborhoods in Pittsburgh, Pennsylvania, one of which experienced Black gentrification during the study's time period. This analysis is unique in its ability to capture experiences of residents who remained in their neighborhood throughout the course of the study, as well as those who moved away from their neighborhood. METHODS: Participants were randomly selected from a larger cohort enrolled in a quasi-experimental study and categorized by whether they lived in a census tract that gentrified, whether they owned or rented their home, and whether they moved from the neighborhood or remained in the same place of residence between 2011 and 2018. Phone interviews lasting approximately 30 min were conducted with participants and were audio recorded and transcribed verbatim. Participants were provided a $40 gift card for their time. Interview data were analyzed using a directed content approach, and Cohen's Kappa was obtained (k = 0.924) to signal good inter-rater reliability. RESULTS: Results showed renters in gentrified census tracts overwhelmingly viewed gentrification trends as a negative change compared to homeowners. Overall, participants from gentrified census tracts reported being relatively satisfied with their neighborhood, though some suggested there were fewer resources in the neighborhood over time; felt their social cohesion had deteriorated over time; and more commonly reflected negative health changes over time. CONCLUSIONS: These findings suggest that while gentrification can bring much needed improvements to neighborhoods, it can also bring other disruptive changes that affect the health and wellbeing of existing residents.

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.

The feasibility and acceptability of a web-based physical activity for the heart (PATH) intervention designed to reduce the risk of heart disease among inactive African Americans: Protocol for a pilot randomized controlled trial.

BACKGROUND: Many studies have used the internet to promote physical activity (PA) in several settings, including the home environment, but few have been tailored for African Americans (AAs). To address this research gap, we conducted focus groups with AAs to inform the development of a web-based intervention, Physical Activity for The Heart (PATH), that leverages openly accessible platforms, such as YouTube, to promote PA in any setting. PURPOSE: To describe the rationale and design of a pilot randomized clinical trial (RCT), that examines the feasibility and acceptability of the PATH intervention among 30 AA adults aged 40--70 years without history of cardiovascular disease. METHODS: A 12-week, single-site, wait-listed RCT with subjects randomized 1:1 to either: 1) treatment group - participants receive the PATH intervention, including the online portal and twice a month phone calls from a PA coach, or 2) attention control group - participants receive a self-help PA handout and twice a month general health newsletter. All participants self-monitor step count using actigraphy. The primary outcomes of this 12-week, pilot RCT are recruitment, retention, and adherence to self-monitoring (Actigraph wear time) and the intervention protocol (PATH utilization). The secondary outcomes include changes in PA (step count, moderate-to-vigorous PA, exercise self-efficacy), and cardiometabolic risk (HbA1C, HDL, LDL, total cholesterol, type 2 diabetes risk score, percent body fat, weight, and waist circumference) from baseline to 12 weeks. CONCLUSIONS: This study will provide PATH intervention feasibility and acceptability data among inactive AA adults and will inform a future, full-scale RCT testing efficacy.

Does opening a supermarket in a food desert change the food environment?

Improving access to healthy foods in low-income neighborhoods is a national priority. Our study evaluated the impact of opening a supermarket in a 'food desert' on healthy food access, availability and prices in the local food environment. We conducted 30 comprehensive in-store audits collecting information on healthy and unhealthy food availability, food prices and store environment, as well as 746 household surveys in two low-income neighborhoods before and after one of the two neighborhoods received a new supermarket. We found positive and negative changes in food availability, and an even greater influence on food prices in neighborhood stores. The supermarket opening in a 'food desert' caused little improvement in net availability of healthy foods, challenging the underpinnings of policies such as the Healthy Food Financing Initiative.
