A multisite examination of sex differences in cardiac rehabilitation barriers by participation status

BACKGROUND

Despite its proven benefits and need, women are significantly less likely than men to participate in and complete cardiac rehabilitation (CR). The purpose of this study was to quantitatively investigate sex differences in CR barriers by participation status.

METHODS

Cardiac outpatients (1496, 430 female, 28.7%) of 97 cardiologists completed a mailed survey to discern CR participation. Respondents were asked to rate 19 CR barriers on a 5-point Likert scale.

RESULTS

Five hundred twenty-nine (43%) respondents self-reported participating in CR, with men being more likely to participate (p < 0.05). There was no significant sex difference in total number of CR barriers, but differences in individual barriers were found. For CR participants, t tests revealed significant sex differences in the perception of exercise as tiring or painful (p = 0.042) and work responsibilities (p = 0.013). For CR nonparticipants, women rated the following barriers as greater than men: transportation (p = 0.025), family responsibilities (p = 0.039), lack of CR awareness (p = 0.036), experiencing exercise as tiring or painful (p = 0.002), and comorbidities (p = 0.009).

CONCLUSIONS

Overall, women do not perceive greater barriers to CR participation than men, but the nature of their barriers differs, particularly among nonparticipants. Beliefs about the value of CR, awareness, and exercise parameters are all modifiable barriers that should be addressed among women.

Degree and correlates of cardiac knowledge and awareness among cardiac inpatients

OBJECTIVE

To investigate the degree of CHD awareness as well as symptom, risk factor, and treatment knowledge in a broad sample of cardiac inpatients, and to examine its sociodemographic, clinical and psychosocial correlates.

METHODS

1308 CHD inpatients (351 [27.0%] female), recruited from 11 acute care sites in Ontario, participated in this cross-sectional study. Participants were provided with a survey which included a knowledge questionnaire among other measures, and clinical data were extracted from medical charts.

RESULTS

855 (68.8%) respondents cited heart disease as the leading cause of death in men, versus only 458 (37.0%) in women. Participants with less than high school education (p<.001), an annual family income less than $50,000CAD (p=.022), low functional capacity (p=.042), who were currently smoking (p=.022), who had no family history of heart disease (p<.001), and who had a perception of low personal control (p=.033) had significantly lower CHD knowledge.

CONCLUSIONS

Awareness of CHD is not optimal, especially among women, South Asians, and those of low socioeconomic status. CHD patients have a moderate level of disease knowledge overall, but greater education is needed.

PRACTICE IMPLICATIONS

Tailored educational approaches may be necessary for those of low socioeconomic status, particularly with regard to the nature of CHD, tests and treatments.

Coronary heart disease prevention: views on women's gender-based perceptions and meanings

The construct of gender is typically differentiated from that of sex on the basis that it is socioculturally created rather than biophysically endowed. There has been some investigation regarding the relationship of gender to coronary heart disease prevention and risk factor management. However, mechanisms underlying the influence of gender on these important outcomes have not yet been fully examined or explained. There is a complex interplay among and between the sociocultural environments in which women live and the biophysical outcomes they experience. Funding agencies need to advance a research agenda aimed at prospectively examining the issues surrounding gender and development of coronary heart disease, as well as developing and testing practical and sustainable gender-specific interventions.

Does the Y chromosome make a difference? Gender differences in attempts to change cardiovascular disease risk factors

PURPOSE

The purpose of this study was to determine if gender differences exist in attempts to change cardiovascular disease (CVD) risk factor behaviors, specifically cigarette smoking, sedentary lifestyle, and overweight, and if the success of these attempted behavior changes also differs by gender in the Pawtucket Heart Health Program (PHHP).

METHODS

The risk factors were considered in reference to individuals who needed to change a particular risk factor behavior. Data were gathered from three different sources within the PHHP (the contact card registry of participants and both cross-sectional and cohort household surveys).

RESULTS

Women were much more likely than men to participate in PHHP risk factor programs related to smoking, exercise, or weight loss. Women were also more likely than men to self-report making attempts to change these risk factor behaviors. Men self-reported to have a greater percentage of long-term smoking cessation success than women, although men and women had similar success rates related to weight loss and increasing physical activity. Men who reported being at least 20% overweight at baseline achieved significantly greater self-reported weight loss when followed up about 8.5 years later than women who were overweight at baseline.

CONCLUSIONS

More research needs to be done to find ways to help women become more successful at modifying CVD risk factor behaviors. In addition, emphasis must be placed on ways to help men initiate and increase the number of attempts they make to change these same risk factor behaviors.

Women’s Perceptions of Personal Cardiovascular Risk and Their Risk-Reducing Behaviors

• Background Coronary heart disease is the leading cause of death in women. Risk factors include smoking, hypertension, dyslipidemia, diabetes mellitus, and obesity. Without an understanding of these risk factors, women are poorly prepared to carry out preventive self-care actions to reduce their risk.

• Objectives To describe perceptions of cardiovascular risk factors and risk-reducing behaviors among women with newly diagnosed coronary heart disease.

• Methods A descriptive study was done in a large midwestern suburban hospital. A nonprobability sample of 33 women with coronary heart disease completed a mail questionnaire. Data were collected by using the Coronary Heart Disease Knowledge Test, the Health-Promoting Lifestyle Profile II, and questions developed for the study.

• Results Thirty-three women responded. Mean age was 65.64 years (range, 36–85 years; SD, 11.32 years); mean educational level was 12.67 years (range, 8–18 years; SD, 1.79 years). Most of the respondents could not identify personal cardiovascular risk factors; the risks identified were considerably fewer and differed from those documented in the women’s medical records. Women reported moderate levels of most risk-reducing behaviors and low levels of physical activity.

• Conclusions Women with coronary heart disease may not know what risk factors they have. Women must have their risk factors assessed and should be counseled about those risks.

Women and coronary heart disease

Coronary heart disease (CHD) is the leading cause of death in men and women in the United States. The incidence of CHD during midlife is lower in women than men, but the gap narrows with each decade. Because women have a longer life span than men, the absolute numbers of CHD deaths are roughly equal. Effective diagnosis of CHD in women requires the recognition of gender differences in presentation and pathogenesis. Women present with atypical symptoms and are less likely to have adequate primary prevention. This article discusses the differences between men and women in CHD and examines the assessment, diagnosis, and clinical management of CHD in women.

Exercise testing in special populations: athletes, women, and the elderly

Exercise testing in special populations such as athletes, women, and the elderly requires additional considerations from the clinician. Different protocols, as well as special accommodations, may be necessary for performing the test. Symptomatic athletes may have a number of cardiac conditions that lead to ischemic changes on the exercise test. Asymptomatic athletes often use serial exercise testing to evaluate the efficacy of training programs. For women and the elderly, assessment of risk factors and evaluation of symptoms are important considerations before performing the exercise test. Negative exercise test findings suggest a low risk for future cardiovascular events. Positive exercise test findings must be interpreted in light of the individual's pre-test probability. Assessment of the needs of these patients allows the clinician to tailor the exercise test to produce useful information.
