Innovative care delivery model to address obesity in older African-American women: Senior Wellness Initiative and Take Off Pounds Sensibly collaboration for health (SWITCH)

Obesity among African American people in the United States: A review

Obesity is a growing public health crisis in the United States and is associated with a substantial disease burden due to an increased risk for multiple complications, including cardiovascular and metabolic diseases. As highlighted in this review, obesity disproportionately affects the African American population, women in particular, regardless of socioeconomic status. Structural racism remains a major contributor to health disparities between African American people and the general population, and it limits access to healthy foods, safe spaces to exercise, adequate health insurance, and medication, all of which impact obesity prevalence and outcomes. Conscious and unconscious interpersonal racism also impacts obesity care and outcomes in African American people and may adversely affect interactions between health care practitioners and patients. To reduce health disparities, structural racism and racial bias must be addressed. Culturally relevant interventions for obesity management have been successfully implemented that have shown benefits in weight management and risk-factor reduction. Strategies to improve health care practitioner-patient engagement should also be implemented to improve health outcomes in African American people with obesity. When managing obesity in African American people, it is critical to take a holistic approach and to consider an individual's social and cultural context in order to implement a successful treatment strategy.

Community-engaged and community-based participatory research to promote American Heart Association Life's Simple 7 among African American adults: A systematic review

BACKGROUND

Cardiovascular disease (CVD) is the leading cause of death in the United States and African Americans (AA) have a disproportionately greater burden of CVD as compared to Whites. The American Heart Association (AHA) Life's Simple 7 (LS7) framework outlines goals for attaining ideal cardiovascular health. Yet, there is a lack of evidence summarizing best practices to maximize LS7 attainment. The objective of the present study was to systematically review the extant peer-reviewed literature on community-engaged and community-based participatory research (CBPR) aimed at improving one or more LS7 metrics among AA.

METHODS

PubMed, CINAHL, and Embase databases were searched. We included articles that reported quantitative results for one or more of the following LS7 metrics: physical activity, diet, cholesterol, blood pressure, body mass index, smoking, and glycemia. We included analyses with a greater than 50% AA study population focused on adults (≥18 years of age).

RESULTS

Of the 1008 unique studies identified, 54 met inclusion criteria; 27 of which were randomized controlled trials. 50% of studies assessed more than one LS7 metric but only two studies evaluated all seven of the LS7 metrics. No studies had a high proportion of AA males. 40 studies improved at least one LS7 metric at the study end-point. Formative research was used in many studies to guide intervention design. Studies were of varying quality, but overall rated "fair" using a modified approach to the National Institute of Health quality assessment tool.

CONCLUSION

There is insufficient data to recommend a specific community-engaged or CBPR intervention to improve attainment of LS7 metrics among AA. Future studies using rigorous methodology with increased gender diversity and utilizing the AHA LS7 framework are required to establish a validated program to improve LS7 in AAs.

Engaging African American women in research: an approach to eliminate health disparities in the African American community

OBJECTIVE

To explore the success of community-based participatory research [CBPR] in engaging African American women to achieve health equity by elucidating community, trust, communication and impact. Recommendations helpful for researchers interested in engaging communities to achieve health equity in the USA are included.

INRODUCTION

African American women experience health disparities of multifactorial etiology and are underrepresented in research. CBPR is a collaborative approach that incorporates perspectives, which address the intricate determinants of health and has been reported as an effective means to address health disparities. Yet, the science of CBPR seems elusive to researchers in the medical field. The opportunity exists to better understand and expand the use of the principles of engagement, replication, and sustainability in engaging African American women in health research.

METHODS

A variety of literature regarding engaging African American women in community-based participatory research was reviewed.

RESULTS

CBPR focused on robust engagement of marginalized groups continues to be validated as a vital approach to the elimination of disparities and improved health for all, especially ethnic and racial minority populations. However, limited evidence of focused engagement of African American women was found. Making specific outreach to African American women must be a community and patient engagement priority to achieve health equity.

CONCLUSIONS

Continued research is needed which specifically focuses on building and sustaining engagement with African American women and their communities. This research can transform healthcare access, experiences and outcomes by yielding actionable information about what African American women need and want to promote wellness for themselves and their communities.

Obesity in older persons

PURPOSE OF REVIEW

There is an increasing number of reports suggesting that indicators of obesity for the general adult population may need to be modified; that the magnitude of risk is attenuated or that adiposity may even be protective; and that additional adverse outcomes specific to older persons need to be considered. Finally, there are benefits and adverse effects of weight loss programmes for older persons. This article reviews publications addressing these issues from 2013 to March 2014.

RECENT FINDINGS

BMI was not considered to be as good an indicator of obesity because of loss of muscle mass with age. Higher body weight seems to be protective among older persons with chronic diseases or geriatric syndromes. Increased adiposity together with decreased muscle mass (sarcopenic obesity) is associated with adverse outcomes, although there is no consensus regarding the definition. Intentional weight loss has health benefits but is accompanied by muscle and bone loss, and therefore programmes should include components to counteract these changes.

SUMMARY

The magnitude of health risk associated with obesity is attenuated with age, and mild increase in adiposity may be beneficial for those who are frail and/or with chronic diseases. Weight loss programmes should include resistance exercises to counteract muscle loss.
