The Development and Pilot Testing of an Evidence-Based Cardiovascular Disease Risk-Prevention Program to Promote Healthy Lifestyle Behaviors Among African-American College Students - Rams Have HEART.

Objectives: Cardiovascular disease (CVD) is the leading cause of death in the United States. Among the risk factors for college students, obesity and physical inactivity are disproportionately high among African Americans (AAs), and while studies of the obesity epidemic have increased in recent years, few target AA college-aged students. This study developed and piloted an evidence-based, 15-week, 3-credit hour, CVD risk-prevention and intervention course, Rams Have HEART that used e-learning, web-based technologies, and a mobile application and compared its effects against a control course. Methods: Two cohorts were recruited in a two-year period; 124 AA college students voluntarily consented to participate in the study, with n = 63 representing the control group and n = 61 representing the intervention. CVD risk factors were assessed by examining blood markers and anthropometric measurements. Demographic, clinical, and survey data (physical measures, blood marker investigation, and self-report surveys) were collected at baseline, post-intervention, and follow-up over the academic year. Results: The mean blood markers for lipid panel and glucose results were within the established optimal range. Intake of fruits and vegetables increased along with knowledge of CVD risk factors; 86% of students enrolled in the intervention passed the course; 100% (n = 61) would recommend it to future students. Conclusion: Developing and offering a healthy lifestyle-behavior CVD intervention course to AA college students is feasible and effective in optimizing their awareness of chronic disease risk factors and prompting behavior change.

Rams Have Heart, a Mobile App Tracking Activity and Fruit and Vegetable Consumption to Support the Cardiovascular Health of College Students: Development and Usability Study.

BACKGROUND: With the increasing use of mobile devices to access the internet and as the main computing system of apps, there is a growing market for mobile health apps to provide self-care advice. Their effectiveness with regard to diet and fitness tracking, for example, needs to be examined. The majority of American adults fail to meet daily recommendations for healthy behavior. Testing user engagement with an app in a controlled environment can provide insight into what is effective and not effective in an app focused on improving diet and exercise. OBJECTIVE: We developed Rams Have Heart, a mobile app, to support a cardiovascular disease (CVD) intervention course. The app tracks healthy behaviors, including fruit and vegetable consumption and physical activity, throughout the day. This paper aimed to present its functionality and evaluated adherence among the African American college student population. METHODS: We developed the app using the Personal Health Informatics and Intervention Toolkit, a software framework. Rams Have Heart integrates self-reported health screening with health education, diary tracking, and user feedback modules to acquire data and assess progress. The parent study, conducted at a historically black college and university-designated institution in southeastern United States, consisted of a semester-long intervention administered as an academic course in the fall, for 3 consecutive years. Changes were made after the cohort 1 pilot study, so results only include cohorts 2 and 3, comprising a total of 115 students (n=55 intervention participants and n=54 control participants) aged from 17 to 24 years. Data collected over the study period were transferred using the secure Hypertext Transfer Protocol Secure protocol and stored in a secure Structured Query Language server database accessible only to authorized persons. SAS software was used to analyze the overall app usage and the specific results collected. RESULTS: Of the 55 students in the intervention group, 27 (49%) students in cohort 2 and 25 (45%) in cohort 3 used the Rams Have Heart app at least once. Over the course of the fall semester, app participation dropped off gradually until exam week when most students no longer participated. The average fruit and vegetable intake increased slightly, and activity levels decreased over the study period. CONCLUSIONS: Rams Have Heart was developed to allow daily tracking of fruit and vegetable intake and physical activity to support a CVD risk intervention for a student demographic susceptible to obesity, heart disease, and type 2 diabetes. We conducted an analysis of app usage, function, and user results. Although a mobile app provides privacy and flexibility for user participation in a research study, Rams Have Heart did not improve compliance or user outcomes. Health-oriented research studies relying on apps in support of user goals need further evaluation.

Perceived Risk of Cardiovascular Disease and Health Behaviors in Black College Students.

For college students, the transition from adolescence to young adulthood can be a time of increased stress and negative health behaviors, such as poor diet and physical inactivity, that may lead to cardiovascular disease (CVD), the primary cause of death in the United States. Blacks are disproportionately prone to CVD. Perception of disease risk is a critical predictor of engagement in healthy lifestyle activities intended to reduce CVD development. This project examined the relationship between perceived risk of CVD and health behaviors in Black HBCU students aged 18-25 years. All participants (n = 14) perceived that they were not at risk for heart disease within the next 10 years. Almost half (n = 6, 42.86%) had moderately high CVD risk scores, and three (21.43%) were at high risk for developing CVD. Scores on the subscales for dread risk, risk, and unknown risk were 28.29, 37.67, and 43.86, respectively. Total scores for perceived risk of heart disease ranged from 20 to 80. The Spearman's correlation between these Black college students' perceived dread risk and health responsibility was positive and moderately correlated (rs = 0.62, p = 0.019). A negative and moderate correlation was demonstrated between unknown perceived risk and health responsibility (rs = -0.54, p = 0.046). Thus, higher risk perception is correlated with greater health responsibility, while low risk perception is correlated with less health responsibility. Barriers to healthy lifestyle behaviors identified by the sample included lack of time and sleep, physical inactivity, cost, convenience of unhealthy foods, and low perception of developing CVD. A major implication is the benefit of implementing interventions to modify risk perception and college-specific barriers that increase CVD risk.

The Use of Text Messaging to Promote Physical Activity in African-American College Students: A Feasibility Study.

BACKGROUND: African-American college students are less likely to meet recommended physical activity guidelines to promote health, and are at risk of overweight, obesity, and elevated blood pressure. Text messaging is an emerging international technology shown to engage college students, promote physical activity, and reduce health risks. PURPOSE: To determine the feasibility of using text messaging to promote physical activity among African-American college students enrolled in a unique course focusing on lifestyle behaviors for a healthy heart. SAMPLE: A purposive sample of 11 (n=4 male, n=7 female) African-American college students aged 18-25 years with cell phones capable of receiving messages was used in this study. METHODS: A three-week text-message protocol was piloted using web-based software to evaluate feasibility with post-hoc grouping of participants into responders and non responders. Descriptive statistics and Mann-Whitney U-tests were used to analyze group differences. RESULTS: There was an attrition rate of nearly 91%. Observed engagement was 50% among responders with compliance at 44.44%. Observed engagement and compliance rates were less than 2% among nonresponders. There were no statistically significant differences in underlying variable distributions between groups. Of practical importance, it was noted that prior to texting responder means were higher for walking physical activity, and lower for body mass index, while nonresponders had higher means for vigorous physical activity. CONCLUSION: The literature review indicated that text messaging is a cost-effective technology that can be incorporated into health education courses on HBCU campuses, but this project suggested semester timing is pivotal to feasibility. Implications largely address tailoring text messages to maintain engagement and evaluating the effect of text messages on physical activity level, body mass index, and blood pressure.

Examining the Relationship between Mindfulness, Perceived Stress, and Blood Pressure in African-American College Students.

College students are prone to stress, making them vulnerable to cardiovascular disease (CVD). Harmful health behaviors, such as tobacco or alcohol use, further predispose students to hypertension (HTN). African-Americans (AA) experience increased blood pressure reactivity, and weathering, due to race-related stressors. This interplay makes AA college students good targets for strategies to prevent stress and HTN disease risk. This project examined the relationship between mindfulness, perceived stress and blood pressure among a group of AA college students enrolled in an HBCU healthy heart course. Participants' systolic and diastolic blood pressure averaged 122 mmHg and 76 mmHg, respectively. The Spearman correlation revealed a negative strong relationship between mindfulness and perceived stress (rs = -0.61, p = 0.004). The coefficient of determination indicated that 37% of the variance in mindfulness was explained by perceived stress. College health practitioners should consider integrating mindfulness into course activities and expanding its treatment modality.

Health literacy and computer-assisted instruction: usability and patient preference.

The authors investigated the feasibility of using computer-assisted instruction in patients of varying literacy levels by examining patients' preferences for learning and their ability to use 2 computer-based educational programs. A total of 263 participants 50-74 years of age with varying health literacy levels interacted with 1 of 2 educational computer programs as part of a randomized trial of a colorectal cancer screening decision aid. A baseline and postprogram evaluation survey were completed. More than half (56%) of the participants had limited health literacy. Regardless of literacy level, doctors were the most commonly used source of medical information-used frequently by 85% of limited and adequate literacy patients. In multivariate logistic regression, only those with health insurance (OR = 2.35, p = .06) and computer use experience (OR = 0.39, p = .03) predicted the ability to complete the programs without assistance compared with those without health insurance or prior computer use, respectively. Although patients with limited health literacy had less computer experience, the majority completed the programs without any assistance and stated that they learned more than they would have from a brochure. Future research should investigate ways that computer-assisted instruction can be incorporated in medical care to enhance patient understanding.

Association between domestic violence and HIV serostatus among married and formerly married women in Kenya.

The prevalence of both domestic violence (DV) and HIV among Kenyan women is known to be high, but the relationship between them is unknown. Nationally representative cross-sectional data from married and formerly married (MFM) women responding to the Kenya Demographic and Health Survey 2008/2009 were analyzed adjusting for complex survey design. Multivariable logistic regressions were used to assess the covariate-adjusted associations between HIV serostatus and any reported DV as well as four constituent DV measures: physical, emotional, sexual, and aggravated bodily harm, adjusting for covariates entered into each model using a forward stepwise selection process. Covariates of a priori interest included those representing marriage history, risky sexual behavior, substance use, perceived HIV risk, and sociodemographic characteristics. The prevalence of HIV among MFM women was 10.7% (any DV: 13.1%, no DV: 8.6%); overall prevalence of DV was 43.4%. Among all DV measures, only physical DV was associated with HIV (11.9%; adjusted odds ratio: 2.01, p <.05). Efforts by the government and women's groups to monitor and improve policies to reduce DV, such as the Sexual Offences Act of 2006, are urgently needed to curb HIV, as are policies that seek to provide DV counseling and treatment to MFM women.

An experiential Cardiovascular Health Education Program for African American College Students.

OBJECTIVE: To pilot test a culturally specific and developmentally appropriate curriculum for African-American college students that included self and family assessment to increase awareness of their risk of cardiovascular disease (CVD). METHODS: Students were recruited from a historically Black university to participate in small group workshops focusing to increase their knowledge of their family history of CVD as well as reducing CVD risks. Focus groups were conducted to determine the effectiveness and ways to improve to the intervention. RESULTS: Positive findings were found regarding program efficacy, increased understanding of their family history and strategies to reduce their own risk of CVD. CONCLUSION: Small group experiential workshop approach can be effective in helping African- American college students understand risk and establish healthy heart habits aimed at decreasing risk of coronary heart disease.

Delaying sexual debut as a strategy for reducing HIV epidemic in Kenya.

The study purpose was to determine the association between sexual debut and HIV sero-status, and factors contributing to a positive HIV sero-status. Retrospective cross-sectional data from the Kenya Demographic and Health Survey-2003 were used. Data on women aged 15-49 (n = 3,273) and men aged 15-54 (n = 2,917) accepting HIV testing were retained from three datasets. Stata version 10.1 was used for analyses, p < 0.05. Nine percent of women and 5% of men tested positive for HIV, of whom 46% and 49%, p < 0.001 were aged 16-21 respectively. After adjusting for confounding, women and men who had sexual debut aged 16-21 were 2.31 (95% CI: 1.52-3.51), p < 0.001 and 1.83 (95% CI: 1.07-3.13), p < 0.05 times more likely to test positive for HIV compared to those who never had sex respectively. Early sexual debut continues to be a major risk factor for acquiring HIV infection later in life, suggesting earlier interventions could have a major impact towards fighting the disease.

Promoting heart health: an HBCU collaboration with the Living Heart Foundation and the National Football League Retired Players Association.

INTRODUCTION: Cardiovascular disease continues to be the leading cause of death in the United States and African Americans are disproportionately affected. Cardiovascular disease risk factors such as obesity, hypertension, family history of heart disease, and physical inactivity are often higher in African American young adults. The aim of the current study was to assess cardiovascular disease risk factors at a historically black college and university (HBCU) in North Carolina. METHODS: A collaborative partnership was established that included Living Heart Foundation, the NFL Retired Players Association and a HBCU. Ninety-one students (77 females and 14 males) aged 18 to 55 years (mean, 24 y, SD = 9 y) were recruited via dissemination of flyers, brochures, mass e-mailing, and announcements. Demographic and medical history data were collected. Stata version 10.1 was used for all analyses. RESULTS: Fifty-three percent of the participants reported having experienced a chronic health condition, 32% were overweight (body mass index [BMI], 25-29.9 kg/m2) and 31% obese (BMI > or = 30 kg/m2). Five percent of females and 23% of males had high-density lipoprotein cholesterol of 40 mg/dL or less, indicative of a risk for developing heart disease. CONCLUSION: There is an urgent need to intervene among African American college students and address behavioral risk factors for cardiovascular disease. Such interventions may have a major impact on their overall and future health outcomes. Strategies to be employed need to focus on the integration of culturally appropriate healthy lifestyle programs into the curriculum and university health centers. Consultations with stakeholders for ideas and resources should be encouraged.

La Clínica del Pueblo: a model of collaboration between a private media broadcasting corporation and an academic medical center for health education for North Carolina Latinos.

La Clínica del Pueblo, a health education collaboration between the Maya Angelou Center for Health Equity at Wake Forest University School of Medicine and Qué Pasa Media, Inc., disseminates culturally appropriate health information to the North Carolina (NC) Latino community. The program includes a weekly radio show and corresponding newspaper column addressing four areas: childhood health, adult health, safety, and utilization. The radio show format includes a didactic presentation followed by a call-in question and answer period. Over 200 consecutive weeks of programming have been completed, averaging 11 calls per show. A Latino healthcare resource guide and hotline also provide resource information. Participant demographic information indicates that 50% of the target population comes from Mexico, 60% are women, and 70% of the community is younger than 38 years. There was an increase in the use of the media as a source of health information over the course of the project, from an initial 33% of respondents to 58% in the last survey. Listenership to La Clínica del Pueblo displayed a pronounced increase (18% initial survey to 55% in last survey, P < 0.05). We also observed a statistically significant increase in medical knowledge from initial survey to the last survey (P < 0.001). By multiple regression analysis, we identified 4 predictors of medical knowledge: order of surveys (1 < 3, P < 0.001), education level (P < 0.0001), female gender (P < 0.01) and radio listenership (P < 0.05). The first three variables predicted higher scores; however, radio listening recognition of our radio program was more common among individuals who had lower scores. In conclusion, La Clínica del Pueblo is a model for a novel approach that can reach the Latino community to improve medical knowledge and possibly affect health behaviors in a positive manner.

Enhancing quality of heart failure care in managed Medicare and Medicaid in North Carolina: results of the North Carolina Achieving Cardiac Excellence (NC ACE) Project.

OBJECTIVES: To evaluate an intervention to improve the quality of care of patients with heart failure in managed Medicare and Medicaid plans in North Carolina. BACKGROUND: Utilization of angiotensin-converting enzyme inhibitors (ACE-I) and beta-adrenergic receptor blockers (BB) in heart failure (HF) patients remains suboptimal despite evidence-based guidelines supporting their use. METHODS: Managed care plans identified adult patients with HF during 2000 (preintervention) and from July 1, 2001, through June 30, 2002 (postintervention). Outpatient medical records were reviewed to obtain data regarding type of heart failure, demographics, comorbidities, and therapies. The intervention consisted of guideline summary dissemination, performance audit with feedback, patient-specific chart reminders, and patient activation mailings. RESULTS: We sampled 1613 patients from 5 plans during the preintervention period and 1528 patients during the postintervention period. Assessment of left ventricular function (LVF) increased from 88.2% to 92.5% of patients (P < .0001). Among patients with moderate to severe left ventricular systolic dysfunction, there was no substantive change in treatment with ACE-I or vasodilators, whereas, appropriate treatment with BB increased from 48.3% (with another 11.9% with documented contraindications) to 67.9% (with another 7.5% with documented contraindications). The quality gap decreased from 39.8% to 24.6% (P < .0001). CONCLUSION: LVF assessment improved despite high preintervention rates. Treatment rates with ACE-I and vasodilators remained high, but did not improve. Treatment rates with BB improved substantially translating into a significant public health benefit. Health-care payers should consider development of financial incentives to encourage collaborative quality improvement programs.

Improving diabetes care among low-income North Carolinians: Project IDEAL.

OBJECTIVES: Many barriers exist in implementing evidence-based guidelines for diabetes care, particularlyfor low-income patients. To address this, the North Carolina Project IDEAL (Improving Diabetes Education, Access to Care, and Living) Diabetes Initiative was created STUDY DESIGN/SETTING: Fourteen programs representing different types of agencies and intervention strategies across the state participated in the initiative. DATA COLLECTION: Separate random samples of medical charts of participating patients were reviewed at baseline (n=429) and three-year follow-up (n=656) to assess changes in six process (assessment of hemoglobin A1c, cholesterol blood pressure, and urinary protein; conduction of foot and retina examination) and three outcome (glycemia, blood pressure, and lipid control) measures. Four national guidelines (DQIP, HEDIS, NCEP and ADA) were used as benchmarks. RESULTS: Large increases were observed for some measures (hemoglobin A1c control and testing, LDL-cholesterol testing), while modest increases were observed for others (dilated eye exam, blood pressure testing, and control). CONCLUSIONS/RELEVANCE: Project IDEAL was successful in improving access to high-quality diabetes care for low-income patients. Additional effort is needed to address specific areas of concern, particularly retinopathy screening.

Managed care patients with heart failure: spectrum of ventricular dysfunction and predictors of medication utilization.

BACKGROUND: Heart failure (HF) is a common clinical syndrome resulting in high morbidity and mortality. We examined the spectrum of ventricular dysfunction, and investigated the predictors of angiotensin-converting enzyme (ACE) inhibitor, beta-blocker, and spironolactone prescription in 1613 managed care patients with HF. METHODS AND RESULTS: The diagnosis of HF was made by a HF discharge diagnosis or at least 3 physician encounters with a HF diagnosis during 2000. Logistic regression was used to identify predictors of medication prescription. Preserved systolic function was documented in 37%, moderate-severe systolic dysfunction in 31%, mild systolic in 14%, and 18% had inadequate documentation. The mean age was 69 years, 58% were women, 24% African American, and 60% were Medicare patients. Patients without HF type documented were the least aggressively treated. Coronary artery disease, hypertension, and diabetes predicted increased utilization of ACE inhibitor and beta-blocker therapies. History of nephropathy was associated with less ACE inhibitor prescription. Advancing age predicted less utilization of beta-blockers and spironolactone. Neither ethnicity nor gender influenced medication prescription. CONCLUSION: Preserved left ventricular function was common. Documentation of significant systolic dysfunction was associated with improved quality of care. Interventions to encourage documentation of HF type and further study of HF with preserved systolic function are warranted.

The association of patient trust and self-care among patients with diabetes mellitus.

BACKGROUND: Diabetes requires significant alterations to lifestyle and completion of self management tasks to obtain good control of disease. The objective of this study was to determine if patient trust is associated with reduced difficulty and hassles in altering lifestyle and completing self care tasks. METHODS: A cross-sectional telephone survey and medical record review was performed to measure patient trust and difficulty in completing diabetes tasks among 320 medically underserved patients attending diabetes programs in rural North Carolina, USA. Diabetes tasks were measured three ways: perceived hassles of diabetic care activities, difficulty in completing diabetes-related care activities, and a global assessment of overall ability to complete diabetes care activities. The association of patient trust with self-management was examined after controlling for patient demographics, physical functioning, mental health and co-morbidities. RESULTS: Level of patient trust was high (median 22, possible max 25). Higher trust levels were associated with lower levels of hassles (p = 0.006) and lower difficulty in completing care activities (p = 0.001). Patients with higher trust had better global assessments of overall ability to complete diabetes care activities (p < 0.0001). CONCLUSION: Higher patient trust in physicians is associated with reduced difficulty in completing disease specific tasks by patients. Further studies are needed to determine the causal relationship of this association, the effect of trust on other outcomes, and the potential modifiability of trust.

Quality of heart failure care in managed Medicare and Medicaid patients in North Carolina.

Use of angiotensin-converting enzyme (ACE) inhibitors and beta-adrenergic receptor blockers in patients with heart failure (HF) remains low despite the results of clinical trials and evidence-based guidelines that support their use. The quality of HF care in managed Medicare and Medicaid programs in North Carolina participating in a HF quality improvement program was assessed. Managed care plans identified adult patients with 1 inpatient or 3 outpatient claims for HF during 2000. A stratified random sample of 971 Medicare and 642 Medicaid patients' outpatient medical records from 5 plans were reviewed by trained nurse abstractors to obtain data regarding type of HF, demographics, comorbidities, and therapies. Left ventricular function assessment was performed in 88% of patients. Among 494 patients with systolic dysfunction, 86% were appropriately treated with respect to ACE inhibitors (73% prescribed, 13% had a documented contraindication). In contrast, beta-blocker therapy was appropriate in 61% (49% prescribed, 12% contraindication). There were no significant differences in drug use by insurance, gender, race, or age. Ventricular function assessment and ACE inhibitor prescription rates are higher than beta-blocker prescription rates among Medicare and Medicaid managed care patients in North Carolina. Opportunities for improvement remain, particularly for beta-blocker use.

Patient-centered outcomes of diabetes self-care. Associations with satisfaction and general health in a community clinic setting.

BACKGROUND: Despite the recognition of strategies for diabetes care management, information systems that screen patient diabetes self-care problems are not commonplace, especially among low-income patients. This study examined correlates of three patient-centered outcomes of diabetes self-care (awareness of self-care components, difficulties in diabetes self-care, and adherence to self-care) among low-income diabetic patients. METHODS: Clinical and patient survey data were obtained on 249 participants from 11 primary care community health clinics serving low-income populations in North Carolina in Project IDEAL (Improving Diabetes Education, Access to Care and Living). Measures of patient-centered outcomes of self-care were obtained from the Diabetes Quality Improvement Project (DQIP) Patient-Reported Measures set. RESULTS: A substantial proportion of patients reported difficulty achieving standard self-care treatment goals. The study identified distinct patient characteristics associated with poor self-care outcomes. Increased understanding of self-care components and adherence to them were associated with increased perception of quality of care and, in turn, better general health perceptions in these patients (p < 0.01). CONCLUSIONS: This study identified an unmet need for diabetes self-care knowledge and skills associated with patient outcomes in low-income patients. Routine monitoring of patient-centered self-care outcomes could help improve long-term outcomes of diabetes care in this population.
