The impact of the Prime Time Sister Circles® (PTSC) on blood pressure of low-income mid-life African American women in the United States.

There is a pressing need to develop and evaluate culturally tailored, community-based interventions that address hypertension management among low-income African American women. We employed a randomized controlled trial to test the effectiveness of the Prime Time Sister Circles® Program in reducing blood pressure and body mass index among low-income African American women ages with hypertension. Study participants (N = 339) were African American women aged 40-75 years who were diagnosed with hypertension and received their primary care at government funded health centers in Washington, D.C. Compared to the usual care group, Prime Time Sister Circles® participation was associated with a reduction in systolic BP by - 2.45 (CI - 6.13, 1.23) mmHg, a reduction in diastolic BP by - 3.66 mmHg (CI - 6.32, - 0.99), and a change in BMI by - 0.26 (CI - 2.00, 1.48) from baseline to 15 months. The results suggest that culturally tailored community-based interventions can improve hypertension management in low-income women.

Evaluating the Impact of the Prime Time Sister Circles® Intervention on Reducing Depressive Symptoms Among African American Women with Uncontrolled Hypertension.

BACKGROUND: The Prime Time Sister Circles®, a randomized controlled trial (PTSC-RCT), assessed the impact of a community-based peer support program on hypertension management among African American women 40-75 years of age. While the PTSC-RCT was designed to evaluate changes in blood pressure control, subsequent sub-analyses revealed a high proportion of self-reported depressive symptoms in our sample. Accordingly, we conducted an ancillary investigation of the PTSC intervention on depression to ascertain its impact on reduced depressive symptoms in the study population. METHOD: Depressive symptoms were measured using an adapted version of the Center for Epidemiologic Studies Depression Scale Revised (CES-D-10). We used unadjusted and adjusted fixed effect models. Data for this study came from the PTSC-RCT. We collected data between 2017 and 2018 in Washington, DC. We used a balanced analytical sample of 172 African American, English-speaking women between 40 to 75 years old with uncontrolled hypertension. INTERVENTION: The intervention group participated in a 2-h, peer-based support group once a week for 13 weeks. A trained PTSC facilitator facilitated sessions with experts who delivered content on various topics, including psychosocial wellness (e.g., stress, depressive symptoms, anxiety management, and self-esteem), physical health (e.g., hypertension, inflammation, and heart disease), physical activity, and healthy nutrition. RESULTS: Results from the fixed-effects models indicated that participants in the PTSC program exhibited a greater reduction in CES-D-10 score at three months (Coeff: -1.99, 95% CI: -3.49, -0.49) and at 15 months (Coeff: -2.38, 95% CI: -3.94, -0.83), as compared to those in the control group. CONCLUSIONS: Evidence suggests that the Prime Time Sister Circles® intervention reduced depressive symptoms among African American women with low socioeconomic status and hypertension.

Study protocol of a randomized controlled trial evaluating the Prime Time Sister Circles (PTSC) program's impact on hypertension among midlife African American women.

BACKGROUND: The Prime-Time Sister Circles® (PTSC) program is a multifaceted, community-based peer support intervention targeting African American women who are 40 to 75 years of age. It aims to reduce hypertension disparities observed among African American women by promoting adherence to antihypertensive therapies, including lifestyle modification and therapeutic regimens. METHODS: The PTSC randomized controlled trial will evaluate the effectiveness of the PTSC Program on improved blood pressure control, healthcare utilization attributed to cardiovascular events, and healthcare costs. The study began in 2016 and will end in 2022. African American women who are 40-75 years old, have been diagnosed with hypertension, reside in Washington, D.C. or Baltimore, Maryland, and receive their care from Unity Health Care, a federally qualified health center in Washington, D.C., or Baltimore Medical System, a federally qualified health center in Baltimore, Maryland, are eligible to participate. Those randomized to the intervention group participate in the PTSC Program, which spans 13 weeks and comprises facilitator-led discussions, didactic training about hypertension management, and peer-based problem-solving concerning CVD risk factors and their amelioration. Blood pressure, weight, body mass index, waist circumference, self-reported adherence, physical activity, dietary practices, stress, and healthcare utilization data are collected at baseline, 13 weeks (end of the intervention), 9 months (months post-intervention), and 15 months (one year after the intervention). Healthcare costs will be computed at the end of the study. The study's design is reported in the present manuscript, wherein we employed the SPIRIT checklist to guide its construction. DISCUSSION: Disparities in hypertension prevalence and management observed among mid-life African American women exist as a result of a confluence of structural determinants of health. Consequently, there is a need to develop, implement, and evaluate culturally appropriate and relevant interventions that are tailored to their lived experiences. The PTSC Trial aims to assess the impact of the program on participants' cardiovascular, psychosocial, and cost outcomes. Its results have implications for advancing the science of designing and implementing culturally relevant interventions for African American women.

Evaluating Depressive Symptoms Among Low-Socioeconomic-Status African American Women Aged 40 to 75 Years With Uncontrolled Hypertension: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Depression is one of the leading causes of disability in the United States. African American women of low socioeconomic status with uncontrolled hypertension are at risk of having severe depressive symptoms, yet there is limited research about the mental health of this vulnerable population. Data from the Prime Time Sister Circles randomized clinical trial (PTSC-RCT) study can shed light on the prevalence of depressive symptoms among low-socioeconomic-status older African American women with hypertension. Objective: To determine the prevalence of depressive symptoms among low-socioeconomic-status African American women aged 40 to 75 years with uncontrolled hypertension who receive their care from a federally qualified health center (FQHC) and to identify risk factors associated with depressive symptoms. Design, Setting, and Participants: Cross-sectional analysis of data from the PTSC-RCT of depressive symptomology, measured using an adapted version of the 10-item Center for Epidemiological Studies Depression Scale Revised (CES-D-10). Descriptive statistics were used to characterize the study population. We used logistic regression models to investigate the factors associated with participants with or without symptoms of depression. We used baseline data from the PTSC-RCT study, including 316 African American English-speaking women between ages 40 and 75 years with hypertension (systolic blood pressure ≥140 mm Hg or diastolic ≥90 mm Hg), who received their primary care at a FQHC in Washington, DC, in 2017 and 2018 and were flagged by the FQHC as uncontrolled. Main Outcomes and Measures: We used the CES-D-10 from the Center for Epidemiologic Studies Depression Scale to measure presence of depressive symptoms. Results: A total of 57.0% of the women in the study (180 of 316) scored greater than or equal to 10 on the CES-D-10. Depressive symptoms had a negative association with a postsecondary education (adjusted odds ratio [aOR], 0.492; 95% CI, 0.249-0.968) and a positive association with the number of chronic conditions (aOR, 1.235; 95% CI, 1.046-1.460) and smoking (aOR, 1.731; 95% CI, 1.039-2.881). Conclusions and Relevance: In this study of low-income African American women with uncontrolled hypertension, more than half had symptoms of depression that was associated with less than high-school education, chronic conditions, and smoking. Low-income African American women with uncontrolled hypertension should be screened and adequately treated for depressive symptoms. Trial Registration: ClinicalTrials.gov Identifier: NCT04371614.
