Individual and Neighborhood Influences on the Relationship Between Waist Circumference and Coronary Heart Disease in the REasons for Geographic and Racial Differences in Stroke Study

INTRODUCTION

The objective of this study was to describe how the relationship between waist circumference and incident coronary heart disease (CHD) is influenced by individual and neighborhood factors in the REasons for Geographic and Racial Differences in Stroke (REGARDS) Study.

METHODS

REGARDS is a cohort study of 30,239 US adults. The primary exposure was sex-specific quartiles of waist circumference. Individual covariates included sociodemographic characteristics, health status, health behavior, and usual source of care. Neighborhood (ie, zip code-level) covariates included access to primary care, poverty, rurality, and racial segregation. The main outcome was incident CHD from baseline (2003) through 2017. We used descriptive statistics, Kaplan-Meier curves, and Cox proportional hazard models to analyze the overall sample and race-sex subgroups.

RESULTS

During the study period, 23,042 study participants had 1,499 CHD events. We found a higher risk of incident CHD in the upper quartile of waist circumference compared with the first quartile in all 4 race-sex subgroups except African American men, among whom we found no relationship between waist circumference and incident CHD. Covariates did not attenuate these relationships.

CONCLUSION

In all groups except African American men, waist circumference in the highest quartile was associated with increased risk of incident CHD. Individual and neighborhood factors did not influence the relationship between waist circumference and development of CHD but differentially influenced incident CHD among race-sex subgroups.

Adapting health promotion interventions for ethnic minority groups: a qualitative study

Adaptation of health interventions has garnered international support across academic disciplines and among various health organizations. Through semi-structured interviews, we sought to explore and understand the perspectives of 26 health researchers and promoters located in the USA, UK, Australia, New Zealand and Norway, working with ethnic minority populations, specifically African-, South Asian- and Chinese-origin populations in the areas of smoking cessation, increasing physical activity and healthy eating, to better understand how adaptation works in practice. We drew on the concepts of intersectionality, representation and context from feminist, sociology and human geography literature, respectively, to help us understand how adaptations for ethnic groups approach the variable of ethnicity. Findings include (i) the intersections of ethnicity and demographic variables such as age and gender highlight the different ways in which people interact, interpret and participate in adapted interventions; (ii) the representational elements of ethnicity such as ancestry or religion are more complexly lived than they are defined in adapted interventions and (iii) the contextual experiences surrounding ethnicity considerations shape the receptivity, durability and continuity of adapted interventions. In conclusion, leveraging the experience and expertise of health researchers and promoters in light of three social science concepts has deepened our understanding of how adaptation works in principle and in practice for ethnic minority populations.

The Impact of Disasters on Populations With Health and Health Care Disparities

Context:A disaster is indiscriminate in whom it affects. Limited research has shown that the poor and medically underserved, especially in rural areas, bear an inequitable amount of the burden.

Objective:To review the literature on the combined effects of a disaster and living in an area with existing health or health care disparities on a community's health, access to health resources, and quality of life.

Methods:We performed a systematic literature review using the following search terms: disaster, health disparities, health care disparities, medically underserved, and rural. Our inclusion criteria were peer-reviewed, US studies that discussed the delayed or persistent health effects of disasters in medically underserved areas.

Results:There has been extensive research published on disasters, health disparities, health care disparities, and medically underserved populations individually, but not collectively.

Conclusions:The current literature does not capture the strain of health and health care disparities before and after a disaster in medically underserved communities. Future disaster studies and policies should account for differences in health profiles and access to care before and after a disaster.

Building from within: pastoral insights into community resources and assets

OBJECTIVES

To explore perceptions of community pastors regarding the extent of community resources and assets in a rural, Southern, African American community.

DESIGN AND SAMPLE

Utilizing a qualitative, descriptive design, interviews were conducted with six African American pastors.

MEASURES

Interviews were conducted using a semi-structured interview guide based on an assets-oriented approach.

RESULTS

Pastors discussed various resources and assets, probable within the community that may be considered as support for program development. Key themes included: (1) community strengths, (2) community support, and (3) resources for a healthy lifestyle. The church was identified, throughout the interviews, as a primary source of strength and support for community members.

CONCLUSIONS

In this study of African American pastors, various perceptions of community resources were identified. Findings indicate that a sample, rural, Southern, African American community has a wealth of resources and assets, but additional resources related to health promotion are still necessary to produce optimal results. Specific programs to prevent chronic conditions such as cardiovascular disease can provide an effective means for addressing related health disparities. Programs implemented through churches can reach large numbers of individuals in the community and provide an important source of sustainable efforts to improve the health of African Americans.

Church and Spirituality in the Lives of the African American Community

The African American church is held in the highest esteem by most African Americans. Although the influence of the African American church has been underestimated by physicians and nurses, it could be pivotal in optimizing health status among African Americans. Because of this influence, health care practitioners, including nurses, are now recognizing the important role that the African American church plays in improving the health status of individuals in the African American community. This article illuminates the health and health care concerns of the African American community by considering the traditional lack of equal access for this population and the role that the church can play in not only offering church-based health care services but also improving the health status of church congregations. Future roles of the African American church for improved health status are also suggested.

Effects of nurse-managed telemonitoring on blood pressure at 12-month follow-up among urban African Americans

BACKGROUND

Nearly one in three adults in the United States has hypertension. Hypertension is one of the largest risk factors for cardiovascular diseases, and it is growing in prevalence, especially among African Americans.

OBJECTIVES

To test the hypothesis that individuals who participate in usual care (UC) plus blood pressure (BP) telemonitoring (TM) will have a greater reduction in BP from baseline to 12-month follow-up than would individuals who receive UC only.

METHODS

A two-group, experimental, longitudinal design with block stratified randomization for antihypertensive medication use was used. African Americans with hypertension were recruited through free BP screenings offered in the community. Data were collected through a structured interview and brief physical exam. Cross tabs, repeated measures analysis of variance, and independent t tests were used to analyze the study's hypothesis.

RESULTS

The TM intervention group had a greater reduction in systolic BP (13.0 mm Hg) than the enhanced UC group (7.5 mm Hg; t = -2.09, p = .04) from baseline to the 12-month follow-up. Although the TM intervention group had a greater reduction in diastolic BP (6.3 mm Hg) compared with the enhanced UC group (4.1 mm Hg), the differences were not statistically significant (t = -1.56, p = .12).

DISCUSSION

: Telemonitoring of BP resulted in clinically and statistically significant reductions in systolic BP over a 12-month period; if maintained over a longer period of time, the reductions could improve care and outcomes significantly for African Americans with hypertension.

Cardiovascular Risks and Physical Activity in Middle-Aged and Elderly African American Women

Cardiovascular disease rates are higher in African American women and they have more cardiovascular risk factors than other groups. Although one of the most important cardiovascular risk reduction behaviors is physical activity, few studies have focused on African American women's cardiovascular risk and physical activity. Therefore, the aims of this descriptive pilot study were to describe modifiable cardiovascular risks and to explore physical activity, as measured by pedometer steps, in younger (n = 22; aged 21-45 years) and older (n = 22; aged 46-75 years) community-dwelling African American women. The total number of pedometer steps recorded in 3 days ranged from 1,153 to 52,742. Day 1 steps were significantly different than day 2 and day 3 steps across the sample (F = 5.30, df = 1, P < .05). Risk factors were similar across the age groups. There was no relationship between the 3-day total or average number of daily steps and cardiovascular risks. Thus, interventions may be used in both age groups, with modifications for cohort effects of approach and health status. Given the disparities in cardiovascular disease and the Healthy People 2010 national health objectives, it is important to continue a variety of efforts to assist adult women of all ages to increase their physical activity and to decrease other CVD risks.

A framework for addressing disparities in cardiovascular health

Health disparities are pervasive in the United States. Life expectancy remains higher in women than in men and higher in whites than in blacks by approximately 5 years. In general, the health of racial and ethnic minorities, poor and uneducated people, and those without health insurance is worse than the health of the overall population. The care of these vulnerable groups tends to be of worse overall quality because they have trouble accessing the system, because standards of care are applied to them unevenly, and because health professionals are not consistently trained in culturally sensitive approaches. These disparities have been demonstrated in all aspects of health and healthcare for cardiovascular diseases, including the use of diagnostic and therapeutic interventions, prevalence of cardiovascular risk factors, and access to health information. Examination of national surveys revealed disparities in all cardiovascular disease risk factors, hospitalizations for major cardiovascular disease, overall mortality, and quality of life. Eliminating these disparities is a major public health challenge in the United States. Their causes and underlying mechanisms, however, remain incompletely understood. The healthcare delivery system itself, access to care, quality of care received, communication barriers, individual behaviors, culture and lifestyles, and discrimination and bias all play a part. The pursuit of systems and policy changes to address these determinants remains crucial. We present a strategic framework for eliminating health disparities that takes these determinants into account and provides an opportunity for cardiovascular nurses to make an impact on this important issue.
