Black Smokers' Preferences for Features of a Smoking Cessation App: Qualitative Study.

BACKGROUND: Mobile health (mHealth) interventions for smoking cessation have grown extensively over the last few years. Although these interventions improve cessation rates, studies of these interventions consistently lack sufficient Black smokers; hence knowledge of features that make mHealth interventions attractive to Black smokers is limited. Identifying features of mHealth interventions for smoking cessation preferred by Black smokers is critical to developing an intervention that they are likely to use. This may in turn address smoking cessation challenges and barriers to care, which may reduce smoking-related disparities that currently exist. OBJECTIVE: This study aims to identify features of mHealth interventions that appeal to Black smokers using an evidence-based app developed by the National Cancer Institute, QuitGuide, as a reference. METHODS: We recruited Black adult smokers from national web-based research panels with a focus on the Southeastern United States. Participants were asked to download and use QuitGuide for at least a week before participation in remote individual interviews. Participants gave their opinions about features of the QuitGuide app and other mHealth apps they may have used in the past and suggestions for future apps. RESULTS: Of the 18 participants, 78% (n=14) were women, with age ranging from 32 to 65 years. Themes within five major areas relevant for developing a future mHealth smoking cessation app emerged from the individual interviews: (1) content needs including health and financial benefits of quitting, testimonials from individuals who were successful in quitting, and strategies for quitting; (2) format needs such as images, ability to interact with and respond to elements within the app, and links to other helpful resources; (3) functionality including tracking of smoking behavior and symptoms, provision of tailored feedback and reminders to users, and an app that allows for personalization of functions; (4) social network, such as connecting with friends and family through the app, connecting with other users on social media, and connecting with a smoking cessation coach or therapist; and (5) the need for inclusivity for Black individuals, which may be accomplished through the inclusion of smoking-related information and health statistics specific for Black individuals, the inclusion of testimonials from Black celebrities who successfully quit, and the inclusion of cultural relevance in messages contained in the app. CONCLUSIONS: Certain features of mHealth interventions for smoking cessation were highly preferred by Black smokers based on their use of a preexisting mHealth app, QuitGuide. Some of these preferences are similar to those already identified by the general population, whereas preferences for increasing the inclusivity of the app are more specific to Black smokers. These findings can serve as the groundwork for a large-scale experiment to evaluate preferences with a larger sample size and can be applied in developing mHealth apps that Black smokers may be more likely to use.

Sociodemographic determinants of change in cardiovascular health in middle adulthood in a bi-racial cohort.

BACKGROUND AND AIMS: Cardiovascular health (CVH), as many other aspects of health, is socially patterned. However, little is known about the socioeconomic determinants of following a more or less favourable pattern of CVH change at midlife. METHODS: We used data on 11,049 participants in the Atherosclerosis Risk in Communities (ARIC) study, a prospective, population-based, bi-racial cohort that included participants aged 44-66 years in 1987-1989, who attended a second visit 6 years later. At both visits, CVH was assessed with the American Heart Association's Life's Simple 7 (LS7) score ranging 0-14, based on 7 metrics: cholesterol, blood glucose, blood pressure, smoking, body mass index, physical activity, and diet. An LS7 score ≥8 was considered ideal, <8 was considered poor. Multivariable logistic regression models were used. In a first sample (N = 4416) of participants who started with a poor CVH, we modelled odds of improvement (Poor-Ideal vs. Poor-Poor). In a second sample (N = 6633) with baseline ideal CVH, we modelled odds of deterioration (Ideal-Poor vs. Ideal-Ideal). The determinants considered were baseline age, sex, race, educational level, income and working status. RESULTS: The majority (8,347, 75.5%) of participants remained in the same CVH category at both waves: 28.7% poor-poor, and 46.8% ideal-ideal. The remaining 24.5% were evenly split between improving (11.2%) and deteriorating (13.2%). Compared to poor-poor CVH, older participants displayed higher odds of improving to ideal CVH (OR>58yvs < 50y = 1.41; 95% CI:1.17, 1.69), whereas Black race (vs White, OR = 0.68; 0.57, 0.80), low education (vs high, OR = 0.65; 0.53, 0.79) and low income (vs high, OR = 0.71; 0.57, 0.87)) were associated with lower odds of improvement. Compared to ideal-ideal CVH, Black participants (OR = 1.59; 1.33, 1.89), with low education (OR = 1.98; 1.64, 2.39), low income (OR = 1.57; 1.30, 1.88), and non-working (vs currently working, OR = 1.27; 1.06, 1.51) had greater odds of deterioration to poor CVH. CONCLUSIONS: We identified vulnerable groups at higher risk of worsening their CVH over time: Black people, with low income, low education, and who are unemployed. Efforts to reduce income and educational gaps and address structural racism, which shapes the distribution of health-promoting and health-harming resources, are paramount to reduce inequities in CVH.

Discrimination and Leukocyte Telomere Length by Depressive Symptomatology: The Jackson Heart Study.

BACKGROUND: Psychosocial stressors, such as perceived discrimination and depressive symptoms, may shorten telomeres and exacerbate aging-related illnesses. METHODS: Participants from the Jackson Heart Study at visit 1 (2000-2004) with LTL data and Center for Epidemiological Studies-Depression (CES-D) scores (n = 580 men, n = 910 women) were utilized. The dimensions of discrimination scores (everyday, lifetime, burden of lifetime, and stress from lifetime discrimination) were standardized and categorized as low, moderate, and high. Coping responses to everyday and lifetime discrimination were categorized as passive and active coping. Multivariable linear regression analyses were performed to estimate the mean difference (standard errors-SEs) in LTL by dimensions of discrimination and coping responses stratified by CES-D scores < 16 (low) and ≥ 16 (high) and sex. Covariates were age, education, waist circumference, smoking and CVD status. RESULTS: Neither everyday nor lifetime discrimination was associated with mean differences in LTL for men or women by levels of depressive symptoms. Burden of lifetime discrimination was marginally associated with LTL among women who reported low depressive symptoms after full adjustment (b = 0.11, SE = 0.06, p = 0.08). Passive coping with lifetime discrimination was associated with longer LTL among men who reported low depressive symptoms after full adjustment (b = 0.18, SE = 0.09, p < 0.05); and active coping with lifetime discrimination was associated with longer LTL among men who reported high depressive symptoms after full adjustment (b = 1.18, SE = 0.35, p < 0.05). CONCLUSIONS: The intersection of perceived discrimination and depressive symptomatology may be related to LTL, and the effects may vary by sex.

Prediagnosis social support, social integration, living status, and colorectal cancer mortality in postmenopausal women from the women's health initiative.

BACKGROUND: We evaluated associations between perceived social support, social integration, living alone, and colorectal cancer (CRC) outcomes in postmenopausal women. METHODS: The study included 1431 women from the Women's Health Initiative who were diagnosed from 1993 through 2017 with stage I through IV CRC and who responded to the Medical Outcomes Study Social Support survey before their CRC diagnosis. We used proportional hazards regression to evaluate associations of social support (tertiles) and types of support, assessed up to 6 years before diagnosis, with overall and CRC-specific mortality. We also assessed associations of social integration and living alone with outcomes also in a subset of 1141 women who had information available on social ties (marital/partner status, community and religious participation) and living situation. RESULTS: In multivariable analyses, women with low (hazard ratio [HR], 1.52; 95% CI, 1.23-1.88) and moderate (HR, 1.21; 95% CI, 0.98-1.50) perceived social support had significantly higher overall mortality than those with high support (P [continuous] < .001). Similarly, women with low (HR, 1.42; 95% CI, 1.07-1.88) and moderate (HR, 1.28; 95% CI, 0.96-1.70) perceived social support had higher CRC mortality than those with high social support (P [continuous] = .007). Emotional, informational, and tangible support and positive interaction were all significantly associated with outcomes, whereas affection was not. In main-effects analyses, the level of social integration was related to overall mortality (P for trend = .02), but not CRC mortality (P for trend = .25), and living alone was not associated with mortality outcomes. However, both the level of social integration and living alone were related to outcomes in patients with rectal cancer. CONCLUSIONS: Women with low perceived social support before diagnosis have higher overall and CRC-specific mortality.

A Cluster Randomized Trial of a Community-Based Intervention Among African-American Adults: Effects on Dietary and Physical Activity Outcomes.

Evidence of the effectiveness of community-based lifestyle behavior change interventions among African-American adults is mixed. We implemented a behavioral lifestyle change intervention, Heart Matters, in two rural counties in North Carolina with African-American adults. Our aim was to evaluate the effect of Heart Matters on dietary and physical activity behaviors, self-efficacy, and social support. We used a cluster randomized controlled trial to compare Heart Matters to a delayed intervention control group after 6 months. A total of 143 African-American participants were recruited and 108 completed 6-month follow-up assessments (75.5%). We used mixed regression models to evaluate changes in outcomes from baseline to 6-month follow-up. The intervention had a significant positive effect on self-reported scores of encouragement of healthy eating, resulting in an increase in social support from family of 6.11 units (95% CI [1.99, 10.22]) (p < .01). However, intervention participants also had an increase in discouragement of healthy eating compared to controls of 5.59 units (95% CI [1.46, 9.73]) among family (p < .01). There were no significant differences in changes in dietary behaviors. Intervention participants had increased odds (OR = 2.86, 95% CI [1.18, 6.93]) of increased frequency of vigorous activity for at least 20 min per week compared to control participants (p < .05). Individual and group lifestyle behavior counseling can have a role in promoting physical activity levels among rural African-American adults, but more research is needed to identify the best strategies to bolster effectiveness and influence dietary change.

Adaptation of an Evidence-Based Cardiovascular Health Intervention for Rural African Americans in the Southeast.

BACKGROUND: African Americans (AA) living in the southeast United States have the highest prevalence of cardiovascular diseases (CVD) and rural minorities bear a significant burden of co-occurring CVD risk factors. Few evidence-based interventions (EBI) address social and physical environmental barriers in rural minority communities. We used intervention mapping together with community-based participatory research (CBPR) principles to adapt objectives of a multi-component CVD lifestyle EBI to fit the needs of a rural AA community. We sought to describe the process of using CPBR to adapt an EBI using intervention mapping to an AA rural setting and to identify and document the adaptations mapped onto the EBI and how they enhance the intervention to meet community needs. METHODS: Focus groups, dyadic interviews, and organizational web-based surveys were used to assess content interest, retention strategies, and incorporation of auxiliary components to the EBI. Using CBPR principles, community and academic stakeholders met weekly to collaboratively integrate formative research findings into the intervention mapping process. We used a framework developed by Wilstey Stirman et al. to document changes. RESULTS: Key changes were made to the content, context, and training and evaluation components of the existing EBI. A matrix including behavioral objectives from the original EBI and new objectives was developed. Categories of objectives included physical activity, nutrition, alcohol, and tobacco divided into three levels, namely, individual, interpersonal, and environmental. CONCLUSIONS: Intervention mapping integrated with principles of CBPR is an efficient and flexible process for adapting a comprehensive and culturally appropriate lifestyle EBI for a rural AA community context.

Perceived social support and the risk of cardiovascular disease and all-cause mortality in the Women's Health Initiative Observational Study.

OBJECTIVE: Previous studies have shown social support to be inversely associated with cardiovascular disease (CVD) in men, whereas fewer studies have assessed the relationship in women. The purpose of this study was to evaluate the relationship between perceived social support and cardiovascular outcomes among postmenopausal women enrolled in the Women's Health Initiative Observational Study. METHODS: We examined the relationships between perceived social support and (1) incident coronary heart disease (CHD), (2) total CVD, and (3) all-cause mortality. Participants were Women's Health Initiative Observational Study women, ages 50 to 79 years, enrolled between 1993 and 1998 and followed for up to 10.8 years. Social support was ascertained at baseline via nine questions measuring the following functional support components: emotional/informational, tangible, positive social interaction, and affectionate support. RESULTS: Among women with prior CVD (n = 17,351) and no prior CVD (n = 73,421), unadjusted hazard ratios ranged from 0.83 to 0.93 per standard deviation increment of social support. Adjustment for potential confounders, such as smoking and physical activity levels, eliminated the statistical significance of the associations with CHD and CVD. However, for all-cause mortality and among women free of baseline CVD, the association was modest but remained statistically significant after this adjustment (hazard ratio = 0.95 [95% confidence interval, 0.91-0.98]). No statistically significant association was observed among women with a history of CVD. CONCLUSIONS: After controlling for potential confounding variables, higher perceived social support is not associated with incident CHD or CVD. However, among women free of CVD at baseline, perceived social support is associated with a slightly lower risk of all-cause mortality.

Racial and ethnic differences in atrial fibrillation risk factors and predictors in women: Findings from the Women's Health Initiative.

BACKGROUND: The incidence of atrial fibrillation (AF) is higher in non-Hispanic whites (NHWs) compared with other race-ethnic groups, despite more favorable cardiovascular risk profiles. To explore reasons for this paradox, we compared the hazards of AF from traditional and other risk factors between 4 race-ethnic groups in a large cohort of postmenopausal women. METHODS: We included 114,083 NHWs, 11,876 African Americans, 5,174 Hispanics, and 3,803 Asians from the Women's Health Initiative free of AF at baseline. Women, averaging 63 years old, were followed up for incident AF using hospitalization records and diagnostic codes from Medicare claims. RESULTS: Over a mean of 13.7 years, 19,712 incident cases of AF were recorded. Despite a higher burden of hypertension, diabetes, and obesity, annual AF incidence was lower among nonwhites (0.7%, 0.4%, and 0.4% for African American, Hispanic, and Asian participants, respectively, compared with 1.2% for NHWs). The hazards of AF from hypertension, diabetes, obesity, heart failure, and coronary artery disease were similar across race-ethnic groups. Major risk factors, including hypertension, obesity, diabetes, smoking, peripheral arterial disease, coronary artery disease, and heart failure, accounted for an attributable risk of 50.3% in NHWs, 83.1% in African Americans, 65.6% in Hispanics, and 37.4% in Asians. Established AF prediction models performed comparably across race-ethnic groups. CONCLUSIONS: In this large study of postmenopausal women, traditional cardiovascular risk factors conferred a similar degree of individual risk of AF among 4 race-ethnic groups. However, major AF risk factors conferred a higher-attributable risk in African Americans and Hispanics compared with NHWs and Asians.

Implementation of the power to prevent diabetes prevention educational curriculum into rural African American communities: a feasibility study.

PURPOSE: The purpose of this study was to describe the feasibility of using a community-based participatory research (CBPR) approach to implement the Power to Prevent (P2P) diabetes prevention education curriculum in rural African American (AA) settings. METHODS: Trained community health workers facilitated the 12-session P2P curriculum across 3 community settings. Quantitative (based on the pre- and post-curriculum questionnaires and changes in blood glucose, blood pressure [BP], and weight at baseline and 6 months) and qualitative data (based on semi-structured interviews with facilitators) were collected. Indicators of feasibility included: demand, acceptability, implementation fidelity, and limited efficacy testing. RESULTS: Across 3 counties, 104 AA participants were recruited; 43% completed ≥ 75% of the sessions. There was great demand for the program. Fifteen community health ambassadors (CHAs) were trained, and 4 served as curriculum facilitators. Content and structure of the intervention was acceptable to facilitators but there were challenges to implementing the program as designed. Improvements were seen in diabetes knowledge and the impact of healthy eating and physical activity on diabetes prevention, but there were no significant changes in blood glucose, BP, or weight. CONCLUSION: While it is feasible to use a CBPR approach to recruit participants and implement the P2P curriculum in AA community settings, there are significant challenges that must be overcome.

Comparing effects of tobacco use prevention modalities: need for complex system models.

Many modalities of tobacco use prevention programming have been implemented including various policy regulations (tax increases, warning labels, limits on access, smoke-free policies, and restrictions on marketing), mass media programming, school-based classroom education, family involvement, and involvement of community agents (i.e., medical, social, political). The present manuscript provides a glance at these modalities to compare relative and combined impact of them on youth tobacco use. In a majority of trials, community-wide programming, which includes multiple modalities, has not been found to achieve impacts greater than single modality programming. Possibly, the most effective means of prevention involves a careful selection of program type combinations. Also, it is likely that a mechanism for coordinating maximally across program types (e.g., staging of programming) is needed to encourage a synergistic impact. Studying tobacco use prevention as a complex system is considered as a means to maximize effects from combinations of prevention types. Future studies will need to more systematically consider the role of combined programming.

Social isolation, vital exhaustion, and incident heart failure: findings from the Atherosclerosis Risk in Communities Study.

AIMS: Prospective studies have shown that social isolation (i.e. lack of social contacts) predicts incident coronary heart disease (CHD), but it is unclear whether it predicts incident heart failure (HF) and what factors might mediate this association. HF patients may be more susceptible to social isolation as they tend to be older and may have disrupted social relationships due to life course factors (e.g. retirement or bereavement). We prospectively examined whether individuals with higher vs. low social isolation have a higher incidence of HF and determined whether this association is mediated by vital exhaustion. METHODS AND RESULTS: We estimated incident HF hospitalization or death among 14 348 participants from Visit 2 (1990-1992) in the Atherosclerosis Risk in Communities (ARIC) study using Cox proportional hazard models which were sequentially adjusted for age, race/study community, gender, current smoking, alcohol use, and co-morbidities. We conducted mediation analyses according to the Baron and Kenny method. After a median follow-up of 16.9 person-years, 1727 (13.0%) incident HF events occurred. The adjusted hazard of incident HF was greater for those in the higher vs. low social isolation risk group (hazard ratio 1.21, 95% confidence interval 1.08-1.35). Our data suggest that vital exhaustion strongly mediates the association between higher social isolation and incident HF (the percentage change in beta coefficient for higher vs. low social isolation groups after adjusting for vital exhaustion was 36%). CONCLUSION: These data suggest that greater social isolation is an independent risk factor for incident HF, and this association appears to be strongly mediated by vital exhaustion.

Sustainability of a multiple risk factor intervention on cardiovascular disease in high-risk African American families.

OBJECTIVES: To determine the long-term effect of a community-based risk reduction intervention at five years after completion of a one-year randomized clinical trial and to determine the sustainability of the beneficial effects seen one year after the intervention. METHODS: 30- to 59- year-old African American siblings of probands with premature coronary heart disease (CHD) were randomized for care of multiple CHD risk factors to either one year of community-based care (CBC) provided by a nurse practitioner/community health worker team or enhanced usual care (EUC). At five years, 307 (84.6%) of the siblings returned for reevaluation. MAIN OUTCOME MEASURES: Changes in and achievement of goal levels of low-density lipoprotein cholesterol (LDL-C), systolic and diastolic blood pressure (SBP and DBP, respectively), and smoking cessation at five years. RESULTS: No significant differences were seen between groups in mean LDL-C, SBP, and DBP or in the overall percentages achieving goal LDL-C, blood pressure, or smoking status. Changes after completion of the intervention suggest that the CBC group lost the beneficial effects for mean LDL-C and for percentage at goal LDL-C, while the EUC group continued to improve. CBC was associated with greater sustainability and less refractoriness of one-year results for LDL-C and blood pressure goals. CONCLUSIONS: Although no group differences were found in mean risk factor levels at five years, data indicate that CBC is both feasible and associated with earlier sustainability of positive risk factor changes compared with EUC.
