Antioxidant intake in relation to serum C-reactive protein in mid-life and older African Americans.

Objective: African Americans (AAs) experience greater prevalence of cardiovascular disease (CVD) compared to other ethnic/racial groups. Low-grade chronic inflammation (often quantified by serum C-reactive protein CRP) is a well-documented risk factor for CVD. A healthy diet is plentiful in antioxidant nutrients and is associated with a lower inflammatory status and CVD risk. Our objective was to examine the relationship between dietary intake of antioxidants (carotenoids, vitamins A, C, E, and selenium) and serum CRP concentrations in mid-life and older AAs, while controlling for confounders. Methods: Data were from the baseline phase of a longitudinal church-based intervention study to reduce CVD risk in AAs. Anthropometrics were measured in a standard manner. Fasting serum samples were analyzed with ELISA for CRP. Multiple-pass 24-hour dietary recalls were used to assess intake; self-reported questionnaires were used to collect demographics. Statistical analyses were performed using SPSS Statistics 21 with the level of significance set at p < 0.05. Results: A total of n = 73 participants (n = 51 females) were included in the analyses. The females and males, respectively were 58.9 ± 10.3 and 59.4 ± 9.7 years old, with BMI of 34.6 ± 8.3 and 35.6 ± 9.3 kg/m2 (Mean ± SD). The mean serum CRP was above 0.6 mg/dL, although slightly lower in males. Males consumed more energy (kcal) and met RDA for selenium, whereas females met RDA for vitamin C. Both groups met RDA for vitamin A. All other dietary variables fell below the RDA or had no RDA established. Results from the binary logistic regression did not show significant association between dietary antioxidants and serum CRP in males or females. However, among females, for every unit increase in BMI, there was a 15% increase in serum CRP (OR = 1.15, p = 0.04). Conclusions: Our study does not support the inverse relationship between antioxidants intake and CRP, but does support the evidence for obesity-induced inflammation and suggests the association can be applied to AA women.

A Youth Health Leadership Program: Feasibility and Initial Outcomes.

This study determined the feasibility (attendance, participation and completion) and initial outcomes (food consumption, food acquisition, physical activity and leadership) of a community-based youth health leadership (YHL) program. YHL was developed as a part of a larger childhood obesity prevention coalition in a medium-sized community in North Florida using community-based participatory research approaches. The theory-driven 6-week program included content sessions, application rotation, and health campaign. Data were collected from youth participants (n = 36) and a purposive comparison group (n = 29) via self-administered questionnaire and project records in the first three years of YHL. Feasibility outcomes show that the majority of program participants attended and participated. Completion rates ranged from 61.5% in year one to 100% in years two and three. Significant differences in treatment and comparison groups were noted in frequency of fruit consumption (p < 0.001) and physical activity (p < 0.002). However, there were no clear patterns of improvements for the treatment group. Trends in the data showed that the consumption of foods high in fat, sugar and sodium decreased slightly for the treatment group but increased or remained the same for the comparison group. The leadership outcomes for youth participants show that those reached are furthering their education, participating in activities such as internships, receiving honors, and garnering leadership achievements. This study suggests that a community-based youth health leadership model is feasible, but more work is needed to impact health behaviors. Future research directions are provided.

Lower life satisfaction, active coping and cardiovascular disease risk factors in older African Americans: outcomes of a longitudinal church-based intervention.

This study examined lower life satisfaction, active coping and cardiovascular disease risk factors (diastolic and systolic blood pressure, body mass index, and circumferences) in older African Americans over the phases of an 18-month church-based intervention, using a quasi-experimental design. Participants (n = 89) were 45 years of age and older from six churches (three treatment, three comparison) in North Florida. Lower life satisfaction had a persistent unfavorable effect on weight variables. Active coping showed a direct beneficial effect on selected weight variables. However, active coping was adversely associated with blood pressure, and did not moderate the association between lower life satisfaction and cardiovascular risk factors. The intervention had a beneficial moderating influence on the association between lower life satisfaction and weight variables and on the association between active coping and these variables. Yet, this pattern did not hold for the association between active coping and blood pressure. The relationship of lower life satisfaction and selected cardiovascular risk factors and the positive effect of active coping were established, but findings regarding blood pressure suggest further study is needed.

The Development of Health for Hearts United: A Longitudinal Church-based Intervention to Reduce Cardiovascular Risk in Mid-life and Older African Americans.

This article describes Health for Hearts United, a longitudinal church-based intervention to reduce cardiovascular disease (CVD) risk in mid-life and older African Americans. Using community-based participatory research (CBPR) approaches and undergirded by both the Socio-ecological Theory and the Transtheoretical Model of Behavior Change, the 18-month intervention was developed in six north Florida churches, randomly assigned as treatment or comparison. The intervention was framed around three conceptual components: awareness building (individual knowledge development); clinical learning (individual and small group educational sessions); and efficacy development (recognition and sustainability). We identified three lessons learned: providing consistency in programming even during participant absences; providing structured activities to assist health ministries in sustainability; and addressing changes at the church level. Recommendations include church-based approaches that reflect multi-level CBPR and the collaborative faith model.

Life Satisfaction and Emerging Health Behaviors in Underserved Adolescents: A Narrative Review.

Objectives: Obesity rates continue to rise in underserved adolescents. Obesity is linked to poor mental health outcomes. The purpose of this narrative review is to examine existing literature on life satisfaction and obesity-related emerging health behaviors (sugar-sweetened beverage consumption, sleeping patterns, and screen time) in underserved adolescents. Methods: We conducted a review of articles published in English between January 1995 and November 2021 to develop a narrative summary. Results: In general, few studies have been conducted investigating life satisfaction and the emerging behaviors of sugar-sweetened beverage consumption, sleeping patterns, and screen time use with adolescents, especially underserved adolescents. In the studies reviewed, we noted links between lower life satisfaction and more than once-a-day sugar consumption, including sugar-sweetened beverages, lower life satisfaction and lower sleep duration, and life satisfaction and screen-time, with both positive and negative relationships shown. Conclusions: Given the limitations in the number of studies, recommendations are provided for future research.

Dissemination trial for Health for Hearts United: Model development, preliminary outcomes and lessons learned.

Background: Cardiovascular disease CVD), the leading cause of death in the U.S., is a particular problem for African Americans (AAs). Church-based health interventions are effective in reducing CVD risk, yet few have been successfully disseminated. This paper describes the model development, preliminary health outcomes, and lessons learned from the Health for Hearts United (HHU) dissemination trial which evolved from the longitudinal Reducing CVD Risk Study in a two-county area in North Florida. Community-based participatory research approaches and the socio-ecological model guided the study. Methods: Data for this paper were from health leaders (n = 25) in the first six churches investigated, and the outreach participants (n = 86) they engaged. Health leaders completed survey items (daily servings of fruits/vegetables [F/V], fat consumption [FAT], and daily minutes of physical activity [PA]) and clinical measures (body mass index [BMI]; waist, hip and abdomen circumferences; and systolic and diastolic blood pressure [BP]). For outreach participants, a brief CVD Awareness Quiz was administered. Data were analyzed using description statistics, Pearson correlations, and repeated measures analysis of variance. Results: Findings showed that the dissemination model was implemented by 100% of the churches, and resulted in health outcomes changes for health leaders (significant increases between pre- and post-test in F/V; significant decreases in FAT, BMI, abdomen circumference, with educational level and marital status as selected significant covariates) and in a significant increase in CVD awareness for outreach participants. Lessons learned are discussed. Although preliminary, the results suggest that the HHU dissemination model has promise for reducing CVD risk in AA's.

Sex and Body Circumferences Associated with Serum Leptin in African American Adults.

Objective: Cardiovascular disease (CVD) continues to be a leading cause of death for U.S. adults, especially African Americans (AA). Yet, few studies have examined a comprehensive set of metabolic health and health behavior factors related to CVD risk in this population. This study investigated the relationship between serum leptin and anthropometries (body mass index [BMI], circumferences [waist-WC, hip-HC, and waist/hip ratio W/H]), metabolic health (systolic and diastolic blood pressure [BP], serum lipids, glucose, and C-reactive protein [CRP]), and health behaviors (hours of sleep, physical activity) in midlife and older AAs. Materials and Methods: Participants (n = 89, ≥45 years of age) were AAs in six churches in North Florida enrolled in a broader church-based longitudinal study. Anthropometric measurements, serum analyses, and self-reported items. Results: Serum leptin was positively correlated with gender (being female) (r = 0.623, p < 0.001), BMI log transformed (r = 0.469, p < 0.001), WC (r = 0.440, p < 0.001), HC (r = 0.658, p < 0.001), use of BP medication (r = 0.216, p < 0.05), and serum CRP (r = 0.277, p < 0.01). Correlations by sex showed significant relationships for both men and women between leptin and BMI log transformed, WC, and HC. The final multiple regression model [R2 = 0.758, F(4, 66) = 55.871, p < 0.001] showed that 75.8% of the variance in leptin was explained by being female (ß = 0.65, p < 0.001), WC (ß = 0.26, p < 0.02), and HC (ß = 0.28, p < 0.01). Conclusions: Findings more specifically delineate the variables associated with serum leptin in AAs, particularly WC and HC, and suggest greater attention to possible risk for leptin resistance in AA females.

Health for Hearts United Longitudinal Trial: Improving Dietary Behaviors in Older African Americans.

INTRODUCTION: Church-based interventions have been shown to improve the dietary health of underserved populations, yet few studies have examined sustainability of health behavior change over time. This paper examines dietary outcomes over a 24-month period (baseline and 6, 18, and 24 months) for fruit and vegetable and fat consumption behaviors of African-American participants in the Health for Hearts United church-based intervention in North Florida. STUDY DESIGN: This quasi-experimental, longitudinal trial was conducted from 2009 to 2012. Data were analyzed in 2018. SETTING/PARTICIPANTS: Six churches in a 2-county area (3 treatment, 3 comparison) were selected for the study using community-based participatory research approaches. Participants were African-American adults (aged ≥45 years; n=211 at baseline) randomly selected from the churches, stratified by age and sex. INTERVENTION: Health for Hearts United intervention was developed by the 3 treatment churches. The 18-month intervention was implemented in 3 6-month phases, framed around 3 conceptual components, which included 4 types of programs and 4 key messages. MAIN OUTCOME MEASURES: Fruit and vegetable consumption was assessed using a single item (fruit and vegetable intake) and the National Cancer Institute Fruit and Vegetable Screener. Fat consumption was determined using a single item (fat intake) and the National Cancer Institute Fat Screener. Background characteristics included age, sex, educational level, and marital status. RESULTS: Significant time effects only were found for daily fruit and vegetable intake (p<0.001), fat intake (p<0.001), and the Fat Screener (p<0.001) with dietary improvements in both treatment and comparison groups across the intervention phases. Fruit and Vegetable Screener results showed that time (p<0.001) and the interaction between time and treatment (p<0.01) were significant, with increases in fruit and vegetable consumption over time for both the treatment and comparison groups and with the increase differing between groups. Post hoc analysis revealed that the treatment group had greater increases in fruit and vegetable consumption than the comparison group between Phases 1 and 3 (p=0.03). CONCLUSIONS: Dietary behaviors of mid-life and older African Americans can be improved and sustained over 24 months using a church-based heart health intervention, with similar improvements noted for both comparison and treatment participants. TRIAL REGISTRATION: This study is registered at www.clinicaltrials.govNCT03339050.

The Breast-Cancer Education and Wellness (BE Well) Intervention: Congregants' Intended Participation, Actual Participation, and Perceived Health Outcomes.

Objective. To evaluate a health leader-focused church-based breast cancer prevention intervention in relation to congregants' intended participation, congregants' actual participation, and perceived health outcomes at both individual and church levels using socio-ecological and theory of planned behavior frameworks. Method. Participants for the study were African American adults (n = 52) from six churches in a North Florida county involved in implementing the 9-month, three-phase intervention. Using a pre/post without comparison group design, data were collected via self-administered surveys and analyzed using qualitative and quantitative (descriptive, analysis of variance, linear regression) procedures. Results. There was general alignment between congregants' intended and actual participation when analyzed by content, especially in the areas of food and nutrition and health education. Regarding the number of intended versus actual activities, there was a significant, negative change in physical activity, a slight decline in health education activities, but a slight increase in food and nutrition activities. No significant relationships were found between extent of participation and the individual health outcomes (health ratings, health status), but significant relationships were found between extent of participation and church health outcomes (perceived role of church in improving health, p < .001; perceived role of the pastor in improving health, p < .001). Conclusions. The findings demonstrate that (1) congregants may follow through and participate in church-based health activities in which they express interest and that are made available and (2) the extent of their participation may be influenced by the perceived role of both the church and the pastor in improving their health.

Diabetic indicators are the strongest predictors for cardiovascular disease risk in African American adults.

African Americans have higher risk of developing type 2 diabetes and cardiovascular disease (CVD) compared to other racial groups. Modifiable and non-modifiable factors play a role in the development of both diseases. This study assessed diabetes indicators in relation to other CVD risk factors taking into account confounders, among African American adults. This was a cross-sectional study in mid-life and older African Americans (≥45 years) who were recruited from the local churches. Fasting blood was collected and serum analyzed for diabetes indicators, apolipoproteins, adipokines, and lipid profile. CVD risk scores were determined using the American Heart Association and Framingham Risk Score assessments. Homeostasis Model Assessments (HOMAs) were calculated using glucose and insulin concentrations. Confounding variables were assessed by questionnaires. Data were analyzed using SPSS software, version 21, and p<0.05 was deemed significant. Descriptive statistics was used to analyze continuous variables. Frequencies and percentages were used to examine categorical variables. T-tests compared different groups while Pearson correlations provided preliminary relationships and determined variables for multiple regression analyses. A total of n=79 participants were evaluated (69% women), 59.3±9.2 years, BMI=34.7±8.3 (mean ± SD). As expected, AA men had higher fasting blood glucose than women (123.6±54.9 mg/dL versus 99.0±21.8 mg/dL), and AA women had higher insulin (11.8±13.1 mg/dL versus 7.6±6.0 mg/dL). Our study confirmed that it is likely for AA men to have significantly lower adiponectin concentrations in comparison to AA women. Based on the CVD risk assessments, men had a significantly higher risk of developing CVD than women, which has been shown previously. Apolipoproteins, adipokines, and lipid profile also negatively influenced the cardiovascular health outcomes in men. Dietary intake, probably by influencing participants' weight/adiposity, contributed to the differences in cardiovascular outcomes between men and women. In conclusion, the findings of this study revealed that diabetes and serum glucose appeared to be the leading factors for high CVD risk, on the contrary to some other indicators reported in some studies, e.g. hypertension or dyslipidemia.

Eating behaviors of older African Americans: an application of the theory of planned behavior.

PURPOSE: The study applies the theory of planned behavior to explain the fruit and vegetable eating behaviors, a broad construct consisting of preparing, self-monitoring, and consuming fruits and vegetables, of older African Americans. DESIGN AND METHODS: Structural equation modeling was used to examine the applicability of the theory of planned behavior with data from 211 older African American women and men (73% women, 26% men; median age range of 57-63 years) participating in a larger intervention study. RESULTS: Attitudes about eating fruit and vegetables, subjective social norms, and perceived behavioral control were related to older African Americans' intentions to consume fruits and vegetables. Social norms and behavioral intentions were associated with fruit and vegetable eating behaviors. Perceived control did not moderate the influence of behavioral intentions on actual behavior. IMPLICATIONS: Results indicated that the theory of planned behavior can be used to explain variation in older African Americans' eating behavior. This study also emphasizes the value of considering broader behavioral domains when employing the theory of planned behavior rather than focusing on specific behaviors. Furthermore, social service programs aimed at reducing the incidence of diseases commonly associated with poor eating behaviors among older African Americans must consider promoting not only fruit and vegetable consumption but also related behaviors including preparing and self-monitoring by eliminating structural, cognitive, and normative constraints.

Health insurance status, psychological processes, and older African Americans' use of preventive care.

The current study examined the influence of health insurance, psychological processes (i.e. psychological competency and vulnerability), and the interaction of these two constructs on older African Americans' utilization of five preventive care services (e.g. cholesterol screening and mammogram/prostate examination) using data from 211 older African Americans (median age = 60). In addition to direct effects, the influence of health insurance sometimes varied depending on respondents' psychological competency and/or vulnerability. Policies and interventions to increase older African Americans' use of preventive health services should consider structural (e.g. health insurance) and psychological (e.g. psychological competency and vulnerability) factors along with the interaction between these factors.

Reducing cardiovascular disease risk in mid-life and older African Americans: a church-based longitudinal intervention project at baseline.

INTRODUCTION: African Americans (AAs) experience higher age-adjusted morbidity and mortality than Whites for cardiovascular disease (CVD). Church-based health programs can reduce risk factors for CVD, including elevated blood pressure [BP], excess body weight, sedentary lifestyle and diet. Yet few studies have incorporated older adults and longitudinal designs. PURPOSES: The aims of this study are to: a) describe a theory-driven longitudinal intervention study to reduce CVD risk in mid-life and older AAs; b) compare selected dietary (fruit and vegetable servings/day, fat consumption), physical activity (PA) and clinical variables (BMI, girth circumferences, systolic and diastolic BP, LDL, HDL, total cholesterol [CHOL] and HDL/CHOL) between treatment and comparison churches at baseline; c) identify selected background characteristics (life satisfaction, social support, age, gender, educational level, marital status, living arrangement and medication use) at baseline that may confound results; and d) share the lessons learned. METHODS: This study incorporated a longitudinal pre/post with comparison group quasi-experimental design. Community-based participatory research (CBPR) was used to discover ideas for the study, identify community advisors, recruit churches (three treatment, three comparison) in two-counties in North Florida, and randomly select 221 mid-life and older AAs (45+) (n=104 in clinical subsample), stratifying for age and gender. Data were collected through self-report questionnaires and clinical assessments. RESULTS AND CONCLUSIONS: Dietary, PA and clinical results were similar to the literature. Treatment and comparison groups were similar in background characteristics and health behaviors but differed in selected clinical factors. For the total sample, relationships were noted for most of the background characteristics. Lessons learned focused on community relationships and participant recruitment.

Establishing health ministries: leaders' perceptions of process and effectiveness.

Church-based health interventions are one mechanism to address health issues of African Americans. This study determines the perceptions of health leaders regarding the development process for and the effectiveness of church health ministries, using the Precede/Proceed model. Ten health leaders from six medium-sized churches in a North Florida county participated in a 10-month breast health intervention. Data were collected using two methods. A brief questionnaire was administered that included items related to knowledge about breast health, perceptions of and processes for health ministry development, and perceptions of resources used during the intervention. In addition, a focus group was conducted with the health leaders, using a trained moderator, which included questions about their health behaviors prior to and after the project, biggest successes and challenges in establishing their health ministries, and plans for sustaining the health ministry after the project. Questionnaire data were analyzed using descriptive statistics and paired t-tests. Focus group data and open-ended questionnaire responses were transcribed and analyzed using code-based analytic procedures where data were organized into thinking units, categories, and then broader themes. Findings indicate that health leaders perceived that health ministry development focused on a series of steps, including: a) predisposing: health leaders background (personal characteristics, education/profession, health behaviors); b) enabling: support and participation from the pastor; and c) reinforcing: start-up processes (personal contact, public relations, materials and church member involvement) and outputs (activities and partnerships). This study demonstrates that health ministry development involves a sequential process that fits within a broad organizational framework for health behavior change.

The development of a tracking tool to improve health behaviors in African American adults.

Although African Americans (AAs) have high risk for cardiovascular disease, few individual tailored interventions are available to improve healthy lifestyles in this population. The purpose of this study was to develop and pilot-test a tracking tool for AA adults to examine the extent to which participants initiated health goals and were ready for change, improved health behaviors (increased fruit/vegetables and physical activity, decreased fat), and perceived the tool was useful in tracking and improving health behaviors. AA adults (n=11, 40 years or older) were recruited and completed for one week the Health Check Report Card (HCRC), a tracking tool that measures types of food eaten and physical activity using a pre-determined point system. Findings showed that the participants at post-test significantly increased fruit/vegetable consumption. The HCRC was perceived as helpful in tracking health behaviors. This study suggests that the HCRC may be a tool to explore in improving health behaviors of AAs.
