Improving Overall Health Status Through the CHIP Intervention

To evaluate the efficacy of a coronary heart disease prevention program at improving selected health indicators. A randomized controlled health intervention study was used, with 348 participants from metropolitan Rockford, Illinois, followed for 6 months; ages ranged from 24 to 81 years. Health indicators were based on the SF-36v2. Those in the intervention group showed significantly greater increases in scale scores for physical functioning, role-physical, bodily pain, general health perceptions, vitality, social functioning, role-emotional, and mental health. The prevention program improved functional health and well-being scores as well as psychometrically based physical and mental health summary measures.

Changes in neighbourhood food store environment, food behaviour and body mass index, 1981–1990

This paper examines trends in the neighbourhood food store environment (defined by the number and geographic density of food stores of each type in a neighbourhood), and in food consumption behaviour and overweight risk of 5779 men and women. The study used data gathered by the Stanford Heart Disease Prevention Program in four cross-sectional surveys conducted from 1981 to 1990. Four mid-sized cities in agricultural regions of California. In total, 3154 women and 2625 men, aged 25-74 years. From 1981 to 1990, there were large increases in the number and density of neighbourhood stores selling sweets, pizza stores, small grocery stores and fast-food restaurants. During this period, the percentage of women and men who adopted healthy food behaviours increased but so did the percentage who adopted less healthy food behaviours. The percentage who were obese increased by 28% in women and 24% in men. Findings point to increases in neighbourhood food stores that generally offer mostly unhealthy foods, and also to the importance of examining other food pattern changes that may have a substantial impact on obesity, such as large increases in portion sizes during the 1980s.

Knowledge and Behaviour Regarding Heart Disease Prevention in Chinese Canadian Immigrants

Although Chinese are one of the fastest growing minorities in Canada, there is little information about heart disease prevention behaviour in Chinese immigrants. Our objective was to examine the knowledge and practices of Chinese immigrants regarding heart disease prevention. 504 randomly selected Chinese adult immigrants participated in a community-based, in-person survey in Vancouver during 2005. The survey included questions on heart disease prevention knowledge and practices. Although respondents were quite knowledgeable about heart disease risk factors, their behaviours to reduce heart disease risk were generally low. Thirteen percent of respondents consumed five or more servings of fruit/vegetables per day; 37% engaged in regular physical activity; 54% never used tobacco; 81% had received a blood pressure check in the past 2 years; and 54% had received a cholesterol test in the past 5 years. Differences were found in these behaviours by gender, age, English fluency, birth country and duration of residence in North America. The associations are presented between these demographic variables and heart disease prevention behaviours. Heart disease prevention programs are needed in Chinese immigrant populations, especially aimed at increasing fruit/vegetable consumption and regular physical activity. Efforts are also needed to decrease tobacco use and to increase cholesterol testing.

Heart disease knowledge and dietary intakes of African Americans aged 18–30 years

Heart disease knowledge and dietary intakes were assessed with a convenience sample of 192 African Americans aged 18–30 years in Arizona. The Jackson Heart Study food frequency questionnaire and a validated heart disease knowledge instrument were self‐administered. Participants had a mean age of 22.1± 3.7 years, an average BMI of 27.4 ± 6.2, and 70% had at least 1 year of college education. Forty percent of the sample was male. College educated participants consumed slightly more servings of fruits and vegetables daily (2.3± 1.5 vs. 2.0 ± 1.6; p=.248), and less mean fat intakes (g/d) (21.1± 7.5 vs. 25.1 ± 8.8; p=0.003) than non‐college educated participants. Recognition of some prevention measures such as reducing dietary cholesterol (79%), and lowering salt intakes (85%) were high, but other concepts such as reducing dietary animal products (45%) and taking multivitamins (46%) were less known across education, gender and age categories. Women scored higher than men on heart disease knowledge (p=0.001), but awareness that women had unique heart disease risks was low for both genders (53%). Heart disease prevention programs should focus on dietary improvements in this age group of African Americans. Specific examples are knowledge of dietary cholesterol in the diet (e.g. animal products), and the atypical heart disease symptoms found in women, among others.

Contribution of neighbourhood socioeconomic status and physical activity resources to physical activity among women

Introduction:Residence in a deprived neighbourhood is associated with lower rates of physical activity. Little is known about the manifestation of deprivation that mediates this relationship. This study aimed to investigate...

Promoting Heart Health in Women

The purpose of this study was to evaluate the effectiveness of a 5-week, 1 hour per week heart disease prevention program for sedentary female municipal workers with known heart disease risk factors. The program was designed to improve participants' knowledge and perceptions of their personal susceptibility to heart disease. In targeting an ethnically diverse, lower income working population, the researchers also sought to contribute to one of the goals of Healthy People 2010, the elimination of health disparities, specifically the reduction of health disparities in heart disease by 25% by the year 2010. A one-group, repeated measures, quasi-experimental design was employed. Forty-eight women 25 to 66 years old responded to the solicitation and participated in the program. Seventy-five percent were African American, 23% were White, and 2% were Latino. Participants completed a 33-item heart disease knowledge questionnaire, demographic questions, and a single visual analog scale statement to assess perceived susceptibility. Fifty-eight percent of the participants improved their knowledge of heart disease and 50% of the participants increased their perception of susceptibility to heart disease from pre- to post-intervention. The greatest improvement in knowledge and awareness of susceptibility occurred for those with limited knowledge and low perceptions of susceptibility. The gains from this workplace health education project for largely minority female municipal workers were modest, but notable. A workplace health education program for women targeted at increasing their knowledge of heart disease may also increase their perceptions of susceptibility to heart disease.

Heart Disease Prevention Among Chinese Immigrants

There is little information about the heart disease prevention behavior of Asian immigrants. Chinese are the largest Asian sub-group in the United States (US), and 69% of Chinese Americans are foreign-born. Our objective was to describe Chinese immigrants' heart disease prevention practices. A community-based, in-person survey of Chinese men and women was conducted in Seattle during 2005. Our study sample included 395 Chinese immigrants. Only 15% of the respondents consumed five or more servings of fruit/ vegetables per day, and less than one-third (31%) engaged in regular physical activity. Smoking rates were significantly higher among men (21%) than women (1%). About three-quarters (74%) of the study group had received a cholesterol test in the previous five years. Recent immigrants had higher levels of fruit/ vegetable consumption and physical activity than those who had been in the US for 10 years or more. Conversely, longer duration of US residence was positively associated with recent cholesterol testing. Heart disease prevention programs should be developed, implemented, and evaluated in Chinese immigrant populations. These efforts should specifically aim to increase fruit/ vegetable consumption and regular physical activity. Future efforts to increase cholesterol testing should focus on recent immigrants.

The Nonpharmacologic Treatment of Hypertension: How Effective Is It?An Update

Following a hypertension symposium in Los Angeles, CA, in October 2006, a panel was convened to update information about lifestyle changes or the nonpharmacologic treatment of hypertension. Dr Marvin Moser, Clinical Professor of Medicine at the Yale University School of Medicine, moderated the panel. Dr Stanley S. Franklin, Clinical Professor of Medicine and Associate Medical Director of the Heart Disease Prevention Program at the University of California, Irvine, and Dr Joel Handler, Director of the Orange County Kaiser-Permanente Hypertension Clinic and clinical hypertension leader of the Care Management Institute of Kaiser Permanente, participated in the discussion.

The contribution of changes in diet, exercise, and stress management to changes in coronary risk in women and men in the Multisite Cardiac Lifestyle Intervention Program

The relative contribution of health behaviors to coronary risk factors in multicomponent secondary coronary heart disease (CHD) prevention programs is largely unknown. Our purpose is to evaluate the additive and interactive effects of 3-month changes in health behaviors (dietary fat intake, exercise, and stress management) on 3-month changes in coronary risk and psychosocial factors among 869 nonsmoking CHD patients (34% female) enrolled in the health insurance-based Multisite Cardiac Lifestyle Intervention Program. Analyses of variance for repeated measures were used to analyze health behaviors, coronary risk factors, and psychosocial factors at baseline and 3 months. Multiple regression analyses evaluated changes in dietary fat intake and hours per week of exercise and stress management as predictors of changes in coronary risk and psychosocial factors. Significant overall improvement in coronary risk was observed. Reductions in dietary fat intake predicted reductions in weight, total cholesterol, low-density lipoprotein cholesterol, and interacted with increased exercise to predict reductions in perceived stress. Increases in exercise predicted improvements in total cholesterol and exercise capacity (for women). Increased stress management was related to reductions in weight, total cholesterol/high-density lipoprotein cholesterol (for men), triglycerides, hemoglobin A1c (in patients with diabetes), and hostility. Improvements in dietary fat intake, exercise, and stress management were individually, additively and interactively related to coronary risk and psychosocial factors, suggesting that multicomponent programs focusing on diet, exercise, and stress management may benefit patients with CHD.

CardioVision 2020: Program Acceptance and Progress After 4 Years

To report program acceptance and progress after 4 years of a heart disease prevention program. All Olmsted County, Minnesota residents aged >/=20 years. The analysis is based on independent population-based interview samples from 1999, 2000, 2001, and 2003; a dietary questionnaire mailed to interviewees; and blood pressure and cholesterol data from medical records of consenting Olmsted County residents. National, Minnesota, and Olmsted County Behavioral Risk Factor Surveillance System trends for fruit and vegetable consumption, body mass index, participation in physical activity, and smoking are compared. The data were analyzed in 2005. More than 90% of the population considers CardioVision 2020 to be a good, very good, or excellent idea. The program is associated with a 25% reduction in the number of people exposed to environmental tobacco smoke and small but significant increases in consumption of fruits and daily physical activity. The population meeting the serum cholesterol goal increased from 52.0% in 1999 to 57.5% in 2003, and the population meeting the blood pressure goal increased from 53.7% in 1999 to 59.9% in 2003. However, attempts to quit smoking and the amount of time spent in physical activity did not increase. By 2003, nearly 9% of the population reported making a behavior change because of CardioVision 2020. Compared to Minnesota and national trends, fruit and vegetable consumption increased significantly in Olmsted County. The population of Olmsted County views CardioVision 2020 in a positive light. Positive changes in several personal behaviors and risk factor levels have occurred.

Using Behavioral Risk Factor Surveillance Data for Heart Disease and Stroke Prevention Programs

An effective state heart disease and stroke prevention program must be able to monitor changes in heart disease and stroke risk factors of the state population. The Behavioral Risk Factor Surveillance System (BRFSS), a state-based telephone survey, has been an important source for monitoring health-related factors and evaluating the success of programs. The BRFSS currently includes modules on hypertension and cholesterol screening and awareness, cardiovascular disease preventive practices, and recognition of the signs and symptoms of heart attack and stroke as well as relevant modules on fruit and vegetable intake, physical activity, tobacco use, and diabetes. Publication topics included monitoring risk factors and clinical services, assessing progress toward national goals, assessing health disparities, and health status and health-related quality of life issues. States have used the BRFSS data for monitoring health risks in the state, assessing state and national health objectives, determining and providing data for public health campaigns, providing information for legislative proposals, and providing information that helps to initiate collaboration. Major methodologic issues involve validating self-reported data against direct measurement and assessing the effects of changes in telecommunications. As Centers for Disease Control’s (CDC) national heart disease and stroke prevention program and each state health department program develop, state and even local level data will become more important to measure the burden of disease and program impact. State heart disease and stroke prevention programs are encouraged to work closely with state BRFSS coordinators to obtain vital information to measure the burden of heart disease and stroke in their state and to be able to measure program impact on addressing the first and third leading causes of death in the U.S.

Assessment of a register‐based rheumatic heart disease secondary prevention program in an Australian Aboriginal community

Objective: To assess specific performance indicators relating to a register‐based acute rheumatic fever and rheumatic heart disease (ARF/RHD) prevention program in a remote Australian Aboriginal community in order to identify the most appropriate avenues for improvements in delivery of services.Methods: Information kept on the central ARF/RHD register was compared with an amalgamated dataset from three other sources. The community clinic charts of identified patients were reviewed for information regarding accuracy of diagnosis and the number of doses of benzathine penicillin received in the last year. Specific follow‐up arrangements were assessed and compared with practice guidelines.Results: The central ARF/RHD register contained the names of 58 of the 72 (81%) people identified in the community as eligible for inclusion. Only 42% (22/52) of people receiving antibiotic prophylaxis had received 80% or more of the recommended doses in the previous year; service delivery was significantly better for females than males (p=0.004). Individuals in priority category 1 (most severe disease) were found to be receiving follow‐up and investigation according to guidelines. About half the people in categories 2 (moderate disease) and 3 (mild disease) had been inadequately investigated and/or missed out on follow‐up appointments.Conclusions: The ARF/RHD prevention program in this large remote Aboriginal community is struggling to deliver services to a substantial proportion of people who require them. Specific interventions, especially those related to men's health, may be required to correct the problems.

Neighbourhood deprivation and alcohol consumption: does the availability of alcohol play a role?

Previous studies suggest that the physical availability of alcohol may mediate the association between neighbourhood-level material deprivation and alcohol consumption. This study tests the relationships between neighbourhood-level deprivation, alcohol availability, and individual-level alcohol consumption using a multilevel analysis. Data are from cross-sectional surveys conducted between 1979 and 1990 as part of the Stanford Heart Disease Prevention Program (SHDPP). Women and men (n = 8197) living in four northern/central California cities and 82 neighbourhoods were linked to neighbourhood deprivation variables derived from the US census (e.g. unemployment, crowded housing) and to measures of alcohol availability (density of outlets in the respondent's neighbourhood, nearest distance to an outlet from the respondent's home, and number of outlets within a half mile radius of the respondent's home). Separate analyses were conducted for on- and off-sale outlets. The most deprived neighbourhoods had substantially higher levels of alcohol outlet density than the least deprived neighbourhoods (45.5% vs 14.8%, respectively). However, multilevel analyses showed that the least deprived neighbourhoods were associated with the heaviest alcohol consumption, even after adjusting for individual-level sociodemographic characteristics (OR 1.30, CI 1.08-1.56). Alcohol availability was not associated with heavy drinking and thus did not mediate the relationship between neighbourhood deprivation and heavy alcohol consumption. Although alcohol availability is concentrated in the most deprived neighbourhoods, women and men in least deprived neighbourhoods are most likely to be heavy drinkers. This mismatch between supply and demand may cause people in the most deprived neighbourhoods to disproportionately suffer the negative health consequences of living near alcohol outlets.

Eating patterns and cardiovascular disease risk in a Detroit Mexican American population.

The purpose of this study was to examine dietary patterns and cardiovascular risk factors in Hispanic adults living in Southwest Detroit. A descriptive design was used. Self-report baseline data were collected using The Rate Your Plate and Personal Health Risk Assessment questionnaires. A nonrandom sample of 32 Mexican American adults was recruited from a large Roman Catholic Church in Southwest Detroit. Participants were selected if they were enrolled in the larger parent research study to test the effects of a lay health educator intervention and planned to participate in the nutrition education portion of the intervention. Unhealthy eating patterns outnumbered heart healthy eating practices. The majority used higher fat salad dressings; ate fried foods, sweets, and high fat snacks; consumed greater than the desired amounts of regular cheese; drank whole milk; and ate few fruits and vegetables. Lack of physical activity, being overweight, and exposure to second-hand smoke were the most prevalent cardiovascular risk factors. The data suggest that effective community-based heart disease prevention programs that emphasize risk factor screening and cardiovascular risk reduction through heart healthy eating are needed.

Effects of the Quebec Heart Health Demonstration Project on adult dietary behaviours

Background. There are few studies which have evaluated the dietary impact of multiple community-based cardiovascular disease prevention programs. Methods. A 5-year, multifactorial community-based heart disease prevention program was conducted by regional public health departments in three sites: urban, suburban and rural. The experimental and control communities were composed of independent samples of 4,863 adults in 1993 and 5,260 in 1997. The impact of the program on diet was assessed by a validated, self-administered food frequency questionnaire which yielded a Global Dietary Index (GDI). Results. The urban and suburban sites showed improvements in mean GDI in both exposed and non-exposed groups while the rural site mean GDI showed deterioration in both groups (n.s.). The analysis of variance showed that the group × year interaction terms were not significant for each site and sex, indicating that the intervention did not have measurable effects on dietary behaviours. Inclusion of confounding variables did not alter those findings. Analyses of specific food group indices gave similar results. Conclusions. Future intervention programs could benefit from considering physical and social environments as well as public policy changes to improve efficacy.

The realization of a project aimed at reducing the plasmatic lipid level in a large Italian population improves the mean calcium daily intake: the Brisighella Study.

Evaluation of the impact of a coronary heart disease prevention program on calcium, magnesium, phosphorus and vitamin D dietary intake in respect of recommended daily allowances in a large Italian rural population. Retrospective analysis of the Brisighella Study dietary data. The Brisighella Study started in 1972 as a longitudinal study on atherosclerosis risk factors. Brisighella, a rural North Italian village. The Brisighella population's dietary habits were monitored from 1980 every 4 h through a dietary record sheet. 1,350 constantly tested subjects were subdivided according to NHI Consensus Conference on Calcium RDA. In 1986, the studied subjects were invited to reduce their consumption of animal fats and cholesterol through a Nutrition Educational Program (NEP). Before NEP, calcium intake was low in each sex and age category: 20-40% of the populatioin had a daily intake < 550 mg. In 1988, among the 1350 subjects who constantly completed the questionnaire (M = 651, F = 699), the mean calcium intake significantly rose in all age categories: M = 1,003 (25-65 y) and 877 ( > 65) mg/24h (P < 0.001 vs 1984); F = 923 (25-50), 860 (51-65) and 767 (> 65)mg/24h (P < 0.05). In 1992, 3y after the NEP conclusion, calcium intake dropped in each sex and age category. The NEP influenced vitamin D, phosphorus and magnesium intakes less. A collective NEP aimed at lowering saturated fats and cholesterol intakes, improves the calcium intake; in order to maintain their efficacy on nutritional habit changes, these programs must become an ongoing item.

Using focus groups to develop a heart disease prevention program for ethnically diverse, low-income women.

Although low-income women have higher rates of cardiovascular disease (CVD) than higher-income women, health promotion and disease prevention are often low priorities due to financial, family, and health care constraints. In addition, most low-income women live in environments that tend to support and even promote high risk CVD behaviors. Low-income African-American, Hispanic, and White women constitute one of the largest groups at high risk for CVD but few heart disease prevention programs have effectively reached them. The purpose of this project was to use feedback from focus groups to generate ideas about how to best structure and implement future CVD intervention programs tailored to low-income populations. Seven focus groups were conducted with 51 low-income African-American, Hispanic, and White women from two urban and two agricultural communities in California. The women in the study shared many common experiences and barriers to healthy lifestyles, despite their ethnic diversity. Results of the focus groups showed that women preferred heart disease prevention programs that would address multiple CVD risk factors, emphasize staying healthy for themselves, teach specific skills about how to adopt heart-healthy behaviors, and offer them choices in effecting behavioral change. For health information, they preferred visual formats to written formats. They also expressed a desire to develop knowledge to help them separate health "myths" from health "facts" in order to reduce their misconceptions about CVD. Finally, they stressed that health care policies and programs need to address social and financial barriers that impede the adoption of heart-healthy behaviors.

The impact of a community-based heart disease prevention program in a low-income, inner-city neighborhood.

This study evaluated the impact of a 4-year, community-based cardiovascular disease prevention program among adults aged 18 to 65 years living in St-Henri, a low-income, innercity neighborhood in Montreal, Quebec. Awareness of and participation in the program were monitored in 3 independent sample telephone surveys. Self-reported behaviors were compared in St-Henri and a nearby comparison community before and after program implementation in both a 3-year repeat independent sample survey and a 5-year longitudinal cohort telephone survey. Awareness of the program reached 37.4%, but participation was low (2%-3%). There were no secular declines in smoking or high-fat diet; physical inactivity increased in both communities. There were no statistically significant program effects detected in the independent sample surveys, although physical inactivity increased more in the comparison community than in St-Henri. In the longitudinal cohort sample, there was a small, statistically significant increase favoring St-Henri in frequency of cholesterol checkups. Despite careful adaptation of the program to the local social context, there were few community-wide program effects. However, several component interventions showed promise in terms of community penetration and impact.

Evaluation of a Community-Based Latino Heart Disease Prevention Program in Metropolitan Washington D.C.

Cardiovascular disease (CVD) is the leading cause of death for Latinos living in the United States. This population is generally unaware of important lifestyle or behavioral changes that can prevent CVD. The National Heart, Lung, and Blood Institute (NHLBI) in collaboration with a community alliance designed and implemented Salud para su Corazón (Health for Your Heart), a culturally specific, community-based initiative to increase awareness about heart disease risk factors and knowledge about heart disease prevention, and to promote heart-healthy lifestyles. The initiative included messages about smoking cessation; weight loss if overweight; increase in physical activity; and checking blood pressure and cholesterol and treating them if high. Messages were communicated through multiple mass media, interpersonal, and outreach channels. A summative evaluation assessed the impact of the campaign. A pre- and post-campaign survey was conducted in the intervention community to assess whether the messages reached the target audience, and if the initiative had an effect. The sample of respondents included over 300 participants. Results showed that respondents were significantly more aware of risk factors for CVD after the campaign, and had greatly increased their knowledge of ways to prevent heart disease. Current behaviors to prevent cardiovascular disease had not changed at the post campaign measurement. Television, radio, and doctors were the most frequently cited sources of information for learning about the Salud para su Corazón initiative. Furthermore, the specific messages recalled and the source of information cited at post-test were similar to those promoted in the campaign, indicating it was successful in reaching the target audience.
