Our results suggest there are a variety sociodemographic variables severity county-level proportions. As pandemic evolved, communities color disproportionately impacted. Subsequently, it shifted from metropolitan areas...
Introduction A mixed-method, co-design approach to studying the adoption of mobile health (mHealth) technology among African-American (AA) women has not been fully explored. Qualitative data may contextualise existing knowledge surrounding perceptions mHealth AA as part formative work for designing a physical activity application (app). Methods convenience sample 16 completed an informatics survey prior participating in focus groups exploring their use and apps. Survey responses provided...
Background: Psychosocial stress correlates with cardiovascular (CV) events; however, associations between physiologic measures of stressors and CVD remain incompletely understood, especially in racial/ethnic minority populations resource-limited neighborhoods. We examined chronic stress-related neural activity, measured by amygdalar 18 Fluorodeoxyglucose ( FDG) uptake, aortic vascular FDG uptake (arterial inflammation measure) a community-based cohort. Methods: Forty participants from the...
Abstract Background Little is known about the associations between perceived neighborhood social environment (PNSE) and depressive symptoms among African Americans. Furthermore, role of physical activity (PA) as a mediator this association has not been investigated. The two-fold objectives study, therefore, were (1) to examine PNSE Americans, (2) test degree which these mediated by total PA. Methods We used baseline data from Jackson Heart Study (JHS), single-site, prospective,...
Objectives Little is understood about associations between neighborhood characteristics and depression, a cardiovascular disease (CVD) risk factor, in diverse populations. We examined relationships perceived/objective characteristics, CVD markers within the Washington, DC CV Health/Needs Assessment, an evaluation among predominantly African-American (AA) adults resource-limited communities.Method Factor analysis of overall environment perception (NEP) identified three NEP sub-scores:1)...
Neighborhood socioeconomic disadvantage may contribute to depression. This study examined associations between neighborhood disadvantage, measured as deprivation, and depression severity within a broadly representative sample of the U.S. adult population. The (n = 6308 adults) was from 2011-2014 National Health Nutrition Examination Survey. deprivation calculated using 2010 Census shown in tertile form. Depression responses Patient Questionnaire-9 (PHQ-9) continuous score binary Clinically...
Neighborhood environment perception (NEP) has been associated with health outcomes. However, little is known about how NEP relates to routine healthcare utilization. This study investigated the relationship between and independent subfactors utilization behavior, as measured by self-reported (1) usual source of (2) time since last check-up. We used cross-sectional data from Dallas Heart Study, which features a diverse, probability-based sample County residents ages 18 65. logistic regression...
Abstract Background Cardiovascular disease (CVD) is the leading cause of death in world. Given role immune cells atherosclerosis development and progression, effective methods for characterizing cell populations are needed, particularly among disproportionately at risk CVD. Results By using a variety antibodies combined one staining protocol, we were able to identify granulocyte, lymphocyte, monocyte sub-populations by CD-antigen expression from 500 µl whole blood, enabling more extensive...
There is no established method for processing data from commercially available physical activity trackers. This study aims to develop a standardized approach defining valid wear time use in future interventions and analyses. Sixteen African American women (mean age = 62.1 years mean body mass index 35.5 kg/m2) wore the Fitbit Charge 2 20 days. Method 1 defined day as ≥10-hr with heart rate data. removed minutes without data, ≤ - SDs below ≤2 steps, nighttime. Linear regression modeled steps...
Introduction Although physical activity (PA) reduces cardiovascular disease (CVD) risk, inactivity remains a pressing public health concern, especially among African American (AA) women in the USA. PA interventions focused on AA living resource-limited communities with scarce infrastructure are needed. Mobile (mHealth) technology can increase access to interventions. We describe development of clinical protocol for multilevel, community-based, mHealth intervention women. Methods and analysis...
Disparities in diet-related diseases persist among African-Americans despite advances risk factor identification and evidence-based management strategies. Cooking is a dietary behavior linked to improved quality cardiometabolic health outcomes. However, epidemiologic studies suggest that African-American adults report lower frequency of cooking at home when compared other racial groups, reporting on average time. To better understand reported disparities behavior, we sought develop survey...
The aim of this study was to test the mediating role perceived discrimination and stress on associations between neighborhood social environment (PNSE) TV viewing.Baseline data were used for 4716 participants (mean age = 55.1 y; 63.4% female) in Jackson Heart Study (JHS), a large prospective cohort African Americans Jackson, Mississippi. One binary viewing outcome created: ≥4 h/day versus <4 h/day. PNSE variables included violence, problems (higher value more violence/problems), cohesion...
