Design and Rationale of Penn Medicine Healthy Heart, a Randomized Trial of Effectiveness of a Centrally Organized Approach to Blood Pressure and Cholesterol Improvement Among Patients at Elevated Risk of Atherosclerotic Cardiovascular Disease.

RATIONALES: Atherosclerotic Cardiovascular Disease (ASCVD) is the leading cause of morbidity and mortality in the United States. Suboptimal control of hypertension and hyperlipidemia are common factors contributing to ASCVD risk. The Penn Medicine Healthy Heart (PMHH) Study is a randomized clinical trial testing the effectiveness of a system designed to offload work from primary care clinicians and improve patient follow-through with risk reduction strategies by using a centralized team of non-clinical navigators and advanced practice providers, remote monitoring, and bi-directional text messaging, augmented by behavioral science engagement strategies. The intervention builds on prior non-randomized evaluations of these design elements that demonstrated significant improvement in patients' systolic blood pressure and LDL Cholesterol (LDL-C). PRIMARY HYPOTHESIS: Penn Medicine Healthy Heart will significantly improve systolic blood pressure and LDL-C compared to usual care over the 6 months of this intervention. DESIGN: Randomized clinical trial of Penn Medicine Healthy Heart in patients aged 35-80 years at elevated risk of ASCVD whose systolic blood pressure and LDL-C are not well controlled. The intervention consists of four modules that address blood pressure management, lipid management, nutrition, and smoking cessation, offered in a phased approach to give the participant time to learn about each topic, adopt any recommendations, and build a relationship with the care team. SITES: University of Pennsylvania Health System at primary care practices located in inner-city urban and rural/semi-rural areas PRIMARY OUTCOMES: Improvement in systolic blood pressure and LDL-C SECONDARY OUTCOMES: Cost-effectiveness analyses are planned to evaluate the health care costs and health outcomes of the intervention approach. An implementation evaluation is planned to understand factors influencing success of the intervention. ESTIMATED ENROLLMENT: 2,420 active patients of Penn Medicine primary care practices who have clinical ASCVD, or who are at elevated risk for ASCVD, and who are (a) not on statins or have LDL-C > 100 despite being on statins and (b) had systolic blood pressure>140 at two recent ambulatory visits. ENROLLMENT DATES: March 2024-March 2025. The intervention will last 6 months with a 12-month follow-up to determine whether its effects persist. CURRENT STATUS: Enrolling (1,240 enrolled as of August 15, 2024) CLINICAL TRIAL REGISTRATION: NCT06062394.

Testing a Prostate Cancer Educational Intervention in High-Burden Neighborhoods.

To better capitalize on our enhanced understanding of prostate cancer (PCa) risk factors, it is important to better understand how knowledge and attitudes contribute to ethnic disparities in PCa outcomes. The goal of this study was to test the impact of a targeted PCa educational intervention vs. a healthy lifestyle educational control intervention on levels of knowledge, concern, and intention to screen for PCa.We recruited 239 men from neighborhoods with the highest PCa burden in Philadelphia. We assigned 118 men from two of the neighborhoods to the control group 121 men from 2 other neighborhoods to the intervention group. Repeated outcome assessment measures were obtained by administering the survey at baseline, post-session, 1 month post-session, and 4 months post-session.We conducted descriptive statistics to characterize the study sample and linear mixed effect regression models to analyze the intervention's effect on the outcomes. At baseline, we observed no differences in the outcomes between the PCa-targeted intervention and healthy lifestyle control groups.We found that knowledge of PCa and intention to screen increased significantly over time for both the control and intervention groups (p ≤ 0.01 at the 4-month follow-up). In contrast, change in the level of PCa concern was only significant for the intervention group immediately post-session and at 1-month follow-up (p = 0.04 and p = 0.01, respectively).This study showed that gathering at-risk men for discussions about PCa or other health concerns may increase their PCa knowledge and intention to talk to a doctor about PCa screening.

Food outlet visits, physical activity and body weight: variations by gender and race-ethnicity.

PURPOSE: Recent evidence documents significant associations between community design, physical activity and obesity when adjusting for demographic covariates. Yet it is well understood that energy imbalance and weight gain are also a function of dietary patterns, and perhaps the degree of access to healthy food choices. METHODS: The current study builds upon the Atlanta-based SMARTRAQ study of over 10,000 respondents and reports an integrated assessment of obesity impacts of physical activity and food outlet visitation. Respondents in the SMARTRAQ survey aged 25-65 provided BMI, self-reported physical activity levels (IPAQ), demographic factors, and where they went for food over a 2 day period. RESULTS: The relative effect of physical activity, neighbourhood walkability, and food outlet visitation on BMI differed significantly across gender and ethnicity. BMI in females increased with fast food and decreased with grocery store visitation and physical activity, but not with walkability or walking. BMI in males was not related to where they went for food but decreased with walking and overall physical activity and with walkability. Fast food visitation was associated with increased BMI in white respondents and grocery store visitation with decreased BMI in black respondents. Meeting moderate activity guidelines was associated with lower BMI in both black and white respondents, yet walking was only significant in predicting reduced BMI in white respondents. CONCLUSION: Obesity influences of physical activity, walkability, and where people go for food differ significantly across gender and ethnicity and offer important policy implications and insights for future research.

Knowledge and attitudes about deceased donor organ donation in Filipinos: a qualitative assessment.

Fewer ethnic minorities, especially Asian-Americans, become organ donors. There are cultural, religious, and personal barriers to becoming a designated organ donor. Factors that promote or inhibit organ donation in Asians, especially Filipinos, are not well understood. We conducted a series of focus groups to identify barriers and facilitators to organ donation (deceased donor) among Filipinos. Six focus groups were conducted with church members, adolescents, nurses, physicians, organ recipients, and organ donor families. The mean age of adult participants (n = 57) was 52.3 +/- 15 years, 83% were Catholic, and 72% were female. A qualitative theme analysis methodology identified dominant themes related to organ donation in the participants. The major themes were: awareness of organ donation (38%), family beliefs (25%), religion/spirituality (10%), attitude/emotions (10%), personal experience with organ donation (8%), health profession (6%), and cultural issues (3%). Seventy-five percent of the comments about awareness reflected a positive awareness of cultural issues regarding organ donation, and the rest reflected a lack of awareness or misconceptions. Almost every theme was mentioned in all six focus groups. Understanding a specific ethnic group's knowledge, attitudes, and cultural beliefs regarding organ donation is important in the development of educational campaigns to encourage organ donation in ethnic minority populations.

Mediators of lifestyle behavior change in Native Hawaiians: initial findings from the Native Hawaiian Diabetes Intervention Program.

OBJECTIVE: To examine the association of stage of change with diet and exercise behaviors in response to a lifestyle intervention for Native Hawaiians (NHs). RESEARCH DESIGN AND METHODS: A family ('ohana) support lifestyle intervention was compared with a standard intervention in NHs with or at risk for diabetes in two rural communities in Hawaii (n = 147). Stage of change, as a hypothesized mediator of behavior change, and dietary and exercise behaviors were measured at baseline and at 1 year postintervention. RESULTS: Stage of change was significantly associated with positive dietary and exercise behaviors. NHs receiving the 'ohana support (OS) intervention were more likely to advance from pre-action to action/maintenance for fat intake and physical activity than the group who received the standard intervention. Participants in the OS group who advanced from pre-action to action/maintenance showed more improvement in fat intake and physical activity than those in the standard group. CONCLUSIONS: These initial findings suggest that stage of change is an important factor in mediating lifestyle behavior changes in persons with or at risk for diabetes and merits further study among minority populations at high risk for diabetes.

Review of nutritional attitudes and counseling practices of primary care physicians.

I review major issues covered at the International Workshop on Nutritional Attitudes and Practices of Primary Care Physicians and synthesize some of the key findings presented at this workshop and found in the scientific literature. After presenting the rationale for managing nutritional problems in primary health care, I discuss the extent of both practice and international differences. Next, the determinants of attitudes and practices, in terms of both individual and system-level factors, are examined. Various types of interventions and the available data regarding their efficacy are reviewed. I then raise a variety of considerations regarding research methodologies and describe work in progress. Finally, suggestions are advanced regarding opportunities for increasing and improving physicians efforts to manage nutritional concerns and for pursuing promising future directions for better health through nutrition.

Psychosocial correlates of healthful diets among male auto workers.

A better understanding of factors associated with healthful eating practices can improve the design and evaluation of dietary intervention programs. Up to now, little information has been available about these factors in high-risk but healthy populations. This article presents findings of a study of psychosocial factors, including stage of change, and their relationship to patterns of consumption of dietary fat, fiber, and fruits and vegetables in a population of males at increased risk of colorectal cancer. Data are from the baseline survey for the Next Step Trial, a randomized, controlled trial of worksite nutrition and colorectal cancer screening promotion interventions. The respondents (n = 2764) were actively employed or retired auto workers at increased colorectal cancer risk. The psychosocial constructs measured were predisposing factors (benefits, motivation, knowledge; eight items; Cronbach alpha = 0.50), enabling factors (barriers, norms, social support; six items; Cronbach alpha = 0.55), and stages of change for adopting diets lower in fat and higher in fiber/fruits and vegetables. The measures of diet, assessed with a food frequency questionnaire, were intakes of fat, fiber, and servings of fruits and vegetables. There were strong and statistically significant positive associations between both predisposing and enabling scale scores and stages of change for fat and fiber. The percentage of respondents in maintenance stage ranged from 4-80% for fat and 11-81% for fiber, across low to high predisposing scale scores; for enabling scale scores, ranges were 11-71% for fat and 22-81% for fiber. Stage of change was associated with fat, fiber, and fruit and vegetable intake in a stepwise manner, with the greatest change observed between action and maintenance. Correlations with dietary outcomes were significantly greater for predisposing factors (r = -0.30 for fat and 0.36 for fiber) than for enabling factors (r = -0.23 for fat and 0.28 for fiber). Multiple regression models, which included the predisposing and enabling factor scales, stage of change, and covariates related to diet, explained a total of between 16 and 27% of the variance in diet. Predisposing and enabling factors are significantly associated with of stage of change and current diet in this high-risk sample of male auto workers. Stage of change is the strongest correlate examined and seems to serve as a mediating factor for dietary change. Results from the Next Step Trial will provide additional data on whether and how health promotion interventions influence these factors, and whether such changes are associated with dietary change.

Correlates of intentions to obtain genetic counseling and colorectal cancer gene testing among at-risk relatives from three ethnic groups.

OBJECTIVES: An understanding of factors associated with interest in genetic counseling and intentions to obtain colorectal cancer susceptibility testing is an important foundation for developing education, counseling, and genetic services and policies. MATERIALS AND METHODS: A survey was mailed to first-degree relatives of patients diagnosed with colorectal cancer. The respondents (n = 426, 77% response rate) are siblings and adult children of Caucasian, Japanese, and Hawaiian ethnicity. Data collection was guided by a conceptual framework and included questions on demographics, family cancer history, predisposing factors (cancer worry, perceived risk, well-being), and enabling factors (decision preferences, social support, and health care factors). Logistic regression analysis on two binary dependent variables (interest in counseling and intentions to get genetic testing) was performed using Generalized Estimating Equations to account for family clusters. RESULTS: Forty-five % of respondents were interested in genetic counseling, and 26% "definitely" intended to get genetic testing for colon cancer when available. For counseling interest, the most important predictors were education, Hawaiian ethnicity, cancer worry, and family support. Cancer worry, perceived risk, and age (older) were directly, and Japanese ethnicity was inversely, associated with testing intentions. CONCLUSIONS: High rates of interest in cancer genetic testing are similar to those found in other studies. Ethnic differences reveal a paradox between objective population risk (higher for Japanese) and greater concerns (among Hawaiians). The substantial lack of awareness of family history warrants further research. Culturally sensitive education and counseling are needed for managing the likely high demand for personalized information about hereditary cancer risk.

Underreporting of family history of colon cancer: correlates and implications.

Scientific advances in cancer genetics, risk counseling, and management of high-risk individuals require information about familial cancer history. Because some people may not report, or may be unaware of, cancer in their families, it is important to examine the extent of underreporting of family history. We mailed a survey to first-degree relatives of patients with histologically confirmed diagnoses of colorectal cancer (CRC) before age 60 (n = 426, 77% response rate). Analyses examined the extent of underreporting of family history and its predictors (demographics, cancer characteristics, knowledge, and communication) and correlates (cancer worry, perceived risk). Logistic regression analysis was performed using generalized estimating equations to account for family clusters. Despite confirmed diagnosis of CRC in a parent or sibling, 25.4% of respondents reported having no first-degree relative with colon cancer. In multivariate models, the most significant predictor of awareness of a relative's CRC was the stage-at-diagnosis; also, males and those with low knowledge about colon cancer were significantly less aware. Awareness of a relative's CRC was associated with higher cancer worry and risk perception, and being a college graduate contributed independently to increased risk perception. Sole dependence on mailed self-administered questionnaires may lead to substantial underreporting of familial colon cancers, especially those that are in situ or localized.

Efficacy of short-term corticosteroid therapy in outpatient treatment of acute bronchial asthma.

A group of adults with 76 episodes of acute asthma needing emergency therapy, but not requiring hospitalization, were discharged from an emergency department following standardized therapy with bronchodilators. Upon discharge, the patients were treated with a controlled regimen of oral theophylline, and were randomly assigned in double-blind manner to either a placebo treatment (42 patient episodes) or a corticosteroid treatment group (34 patient episodes). The latter were given an intravenous bolus of methylprednisolone followed by an eight-day tapering course of oral methylprednisolone, starting at 32 mg twice a day. Follow-up was carried out seven or 10 days after treatment in the emergency department. Relapse could not be predicted on the basis of peak expiratory flow rates measured during care in the emergency department. Those patients who received corticosteroids had a decrease in the need for repeated emergency care (5.9 percent versus 21 percent for placebo) and fewer respiratory symptoms (15.6 percent versus 36.4 percent for placebo). It is concluded that a short course of high-dose corticosteroids in outpatients reduces the relapse rate and symptoms following an acute asthmatic attack.

An analysis of the transfusion medicine content of the test of the National Board of Medical Examiners.

A two-year (1984-1985) review of 3,764 questions appearing on Part I and Part II of the National Board of Medical Examiners (NBME) indicated 140 (4%) were transfusion medicine (TM)-related. Fewer questions on TM appeared on Part II than Part I (45 vs. 95, P less than 0.001). Unexpectedly, the lowest proportion of questions (excluding psychiatry) in the Part II examination was in the surgery section. Part I NBME appears to adequately reflect and assess the TM content of the medical school curricula, but the number and distribution of questions in Part II of the NBME does not reflect recent changes in the clinical transfusion medicine curricula of many United States medical schools.

Psychosocial determinants of breast self-examination.

To explore the psychosocial determinants of breast self-examination (BSE) among women, we studied a stratified random sample of 264 women students, faculty, and staff in a university community. The dependent variable of the study was self-reported frequency of BSE, and predictors included measures of general health predispositions, variables of the Health Belief Model, the impact of a woman's social network, a set of secondary non-health-related barriers and benefits, and the woman's evaluation of her personal health care system. Analysis of the data showed strong relationships between most of the predictor variables and BSE. Regression analysis showed that variables measuring a woman's recent experience in the health care system were stronger predictors of BSE practice than intrapersonal "health belief" variables. However, the independent variables included in the regression accounted for almost 35 percent of the total variance in BSE practice.

Patient reactions to nutrition education for cholesterol reduction.

The purpose of this study was to assess the perceptions of patients with elevated cholesterol who participated in a physicians' office-based cholesterol management program and to compare patient reports with clinic counseling records. We conducted telephone interviews with 94 patients from five family practice clinics participating in the Physician-Based Nutrition Program (PBNP) between January and March 1988. Within two weeks after a cholesterol counseling visit, interviewers asked patients what happened during the cholesterol management process, queried their understanding of their health risk and recommended dietary changes, and assessed their attitudes toward the educational process and recommended nutrition behavior changes. Results indicate that a large majority of patients understood the problem of high cholesterol and the needed behavior changes and were highly satisfied with the cholesterol management process. However, patients' memory of specific facts, such as their cholesterol levels and behavioral goals, was often incorrect. We discuss the implications of these findings for developing and providing patient cholesterol education.

Components of the working well trial intervention associated with adoption of healthful diets.

INTRODUCTION: This report examines whether variability in the type and amount of the nutrition intervention in a worksite-based intervention could explain dietary outcomes. METHODS: Data are from 55 intervention worksites in the Working Well Trial, a randomized controlled trial of worksite-based health promotion. The components of the nutrition intervention were kickoff event, direct education, interactive activities (e.g., food sampling), contests, printed information picked up by employees, and materials distributed to employees. We measured delivery of the nutrition intervention (i.e., dose) by determining the amount of workforce participation in each intervention component. Diet outcomes were changes in intakes of fat, fiber, and servings of fruits and vegetables (reported on food frequency questionnaires). All variables were aggregated to the worksite level. We correlated the dose variables with indices of receipt of the intervention and with the dietary outcomes. RESULTS: Contests were associated with employee awareness of and participation in the nutrition intervention (r = 0.49 and 0.28, respectively), and interactive activities were associated with intervention participation (r = 0.43). Contests were associated with increased fiber intake and fruit and vegetable consumption (r = 0.36 and 0.31, respectively), and direct education was associated with fruit and vegetable consumption (r = 0.38). All the above correlation coefficients were statistically significant (P < .05). Intervention dose was not associated with changes in fat intake. CONCLUSIONS: It appears that longer, interactive intervention efforts (contests and classes) resulted in more positive outcomes than did one-time activities (such as the kickoffs) or more passive efforts (use of printed materials). There is a need for studies designed to test worksite- and community-based nutrition intervention methods.

Physicians, preventive care, and applied nutrition: selected literature.

The authors review a core of 25 articles (dating from 1982 through 1991) regarding medical school curricula and physicians' knowledge, attitudes, and practices related to nutritional care, with a focus on prevention of coronary heart disease through cholesterol control. They supplement this review by discussing the relation of the core articles' results to those of additional articles, which focus more generally on physicians' health promotion and patient counseling. While there appear to be modest increases in attention to nutrition at various levels of medical training and some improvement in physicians' attitudes about dietary intervention, the authors conclude that both educational opportunities and physicians' practices warrant increased and more effective attention to nutrition. Finally, in light of recent trends and growing efforts to better prepare physicians to play a leading role in preventive care, the authors identify gaps in physicians' training and in research on physicians, preventive care, and applied nutrition.

Comparing the transfusion medicine content of the NBME's examinations in 1984-1985 and 1989-1990.

Recognition of the seriousness of transfusion-transmitted diseases has been demonstrated by U.S. medical schools through the integration of transfusion medicine (TM) content into their curricula. To evaluate the degree to which these changes in curricula have been reflected in the National Board of Medical Examiners' (NBME) examinations, a study conducted in 1991 evaluated the proportions of TM-related items on Parts I and II of the NBME examinations for 1984-1985 versus 1989-1990. Both Part I (basic sciences) and Part II (clinical sciences) demonstrated significant gains in TM items between the comparison periods (p less than .001), with Part II having the higher gain. An analysis of students' knowledge revealed that students in 1989-1990 tended to perform better on TM items than on examination items generally. The increases in TM content and student performance on TM items on the 1989-1990 examinations suggest that the national effort to expand and improve teaching of TM in U.S. medical schools has been effective.

Dietitians' effectiveness and patient compliance with dietary regimens. A pilot study.

Demonstration of dietitians' effectiveness is a necessary prerequisite in documenting the cost-effectiveness of untritional care. In this report, a framework for the study of dietitians' effectiveness and patient compliance with dietary regimens is developed, and the results of a pilot study are presented. Personal, attitudinal, and situational variables that affect adherence to diets were investigated. Findings suggest that (a) disclosure of patient non-compliance varies, depending on the type of question asked and the sequence of questions in an interview; and (b) dietitians with higher "Orientations to Social Influence" use more influence strategies, involve patients in counseling sessions more, and tend to have patients with more appropriate health attitudes and behaviors.

Strategies for nutritional counseling. Dietitians' attitudes and practice.

Responses to a questionnaire distributed to forty-four Midwest dietitians during the development of a program to train dietitians in patient counseling strategies are summarized. Dietitians rated forty-five strategies, divided into five broad categories: Instructional, motivational, behavioral, educational diagnosis, and assessment of compliance. Questions about each strategy included reported use, perceived benefits, and perceived barriers to implementation. Six nutritional consultants rated the relative innovativeness of the strategies. The results provide evidence that strategies currently being developed for training dietitians are compatible with dietetic practice, are often viewed favorably by practitioners, and are "teachable" to nutritionists.

The 5 A day Virtual Classroom: an on-line strategy to promote healthful eating.

Communications technology can help stimulate youth to become involved in health promotion. This article reports on an innovative, Internet-based nutrition program that encouraged children to be advocates for policies that promote eating more fruits and vegetables, the 5 A Day Virtual Classroom. Through this program, students from across the United States discussed the recommendation of 5 A Day at the same time in a classroom without walls. In September 1997 children were asked, "If you were President Clinton, how would you get kids across the country to eat 5 A Day?" Based on content analysis of responses, this article suggests strategies that policymakers could use to encourage children to consume more fruits and vegetables. Approximately 2,600 students participated; 635 entries and 910 suggestions were received. The suggestion categories cited most often were mass media (19.8%), economic issues (15.4%), and social influence (13.8%). The most frequently mentioned specific ideas were to reward children for eating fruits and vegetables and to use presidential authority. Some regional, age, and gender patterns were found. Findings support the potential impact on health education of the 5 A Day Virtual Classroom and of interventions based on communications technology.

Why Americans eat what they do: taste, nutrition, cost, convenience, and weight control concerns as influences on food consumption.

OBJECTIVE: To examine the self-reported importance of taste, nutrition, cost, convenience, and weight control on personal dietary choices and whether these factors vary across demographic groups, are associated with lifestyle choices related to health (termed health lifestyle), and actually predict eating behavior. DESIGN: Data are based on responses to 2 self-administered cross-sectional surveys. The main outcomes measured were consumption of fruits and vegetables, fast foods, cheese, and breakfast cereals, which were determined on the basis of responses to questions about usual and recent consumption and a food diary. SUBJECTS/SETTING: Respondents were a national sample of 2,967 adults. Response rates were 71% to the first survey and 77% to the second survey (which was sent to people who completed the first survey). STATISTICAL ANALYSES: Univariate analyses were used to describe importance ratings, bivariate analyses (correlations and t tests) were used to examine demographic and lifestyle differences on importance measures, and multivariate analyses (general linear models) were used to predict lifestyle cluster membership and food consumption. RESULTS: Respondents reported that taste is the most important influence on their food choices, followed by cost. Demographic and health lifestyle differences were evident across all 5 importance measures. The importance of nutrition and the importance of weight control were predicted best by subject's membership in a particular health lifestyle cluster. When eating behaviors were examined, demographic measures and membership in a health lifestyle cluster predicted consumption of fruits and vegetables, fast foods, cheese, and breakfast cereal. The importance placed on taste, nutrition, cost, convenience, and weight control also predicted types of foods consumed. APPLICATIONS: Our results suggest that nutritional concerns, per sc, are of less relevance to most people than taste and cost. One implication is that nutrition education programs should attempt to design and promote nutritious diets as being tasty and inexpensive.
