Mindfulness in Motion and Dietary Approaches to Stop Hypertension (DASH) in Hypertensive African Americans

OBJECTIVES

Hypertension increases the risk of developing Alzheimer's disease or related dementias. This pilot study's purpose was to examine the feasibility and acceptability of a novel intervention, Mindfulness in Motion (MIM) and Dietary Approaches to Stop Hypertension DASH (MIM DASH), to improve diet, mindfulness, stress, and systolic blood pressure (BP) in older African Americans with mild cognitive impairment (MCI) and hypertension.

DESIGN

Cluster randomized controlled trial.

SETTING

Intergenerational community center in a large metropolitan area.

PARTICIPANTS

African Americans with MCI and hypertension. Participants were divided into six groups randomized 1:1:1 to the MIM DASH group, attention only (non-hypertensive education) group, or true control group. The MIM DASH and attention only interventions were delivered in 8-weekly 2 hour group sessions. MIM included mindful movements from chair/standing, breathing exercises, and guided meditation. The DASH component used a critical thinking approach of problem solving, goal setting, reflection, and self-efficacy. The true control group received a DASH pamphlet at the end.

MEASUREMENTS

Feasibility was tracked through enrollment and attendance records; acceptability was assessed through interviews. Blood pressure was measured using the Omron HEM-907XL Monitor. Dietary intake was measured by DASH-Q. Mindfulness was measured by the Cognitive and Affective Mindfulness Scale. Stress was measured by the Perceived Stress Scale. MCI was determined using the Self-Administered Gerocognitive Examination. Data were collected at baseline and 3-months.

RESULTS

Median session attendance was six for the MIM DASH group and six for the attention only group. There were no changes in diet, mindfulness, or stress. There was a clinically significant reduction in systolic BP in the MIM DASH group (-7.2 mmHg) relative to the attention only group (-.7), and no change between the MIM DASH and true control groups.

CONCLUSION

Results indicate that the MIM DASH intervention was feasible and culturally acceptable in African Americans with hypertension and MCI.

Surgical Treatment of Obesity in Latinos and African Americans: Future Directions and Recommendations to Reduce Disparities in Bariatric Surgery

Introduction: Obesity and metabolic syndrome are increasingly prevalent in the United States, particularly among African Americans and Latinos. Bariatric surgery has become one of the primary treatment modalities for obesity and type 2 diabetes. However, fewer Latinos and African Americans are undergoing bariatric surgery than whites. The aim of this article is to describe the disparities in seeking and accessing bariatric surgery, describe the outcomes following bariatric procedures in Latinos and African Americans, and offer recommendations and future research directions that may assist in addressing these disparities. Methods: Original research and review articles published in English were reviewed. Results: Potential reasons why Latinos and African Americans have low rates of seeking bariatric surgery are described. Disparities in access to care and financial coverage, low rates of referral by primary care providers, and cultural attitudes toward obesity in conjunction with mistrust of the healthcare system are discussed as potential contributors to the low rate of bariatric surgery in Latinos and African Americans. Finally, disparities in bariatric surgery outcomes, comorbidities, and complications are reviewed. Conclusions: Additional research studies in bariatric surgical disparities are needed. Recommendations and future directions that may help to reduce disparities in bariatric surgery are discussed.

Diabetes among US- and foreign-born blacks in the USA

OBJECTIVE

Little is known about diabetes status among US blacks by nativity. This study aims to measure differences in diabetes among US blacks by region of birth and examines potential explanations for subgroup differences.

DESIGN

Data from 47,751 blacks aged 25-74 pooled from the 2000-2013 waves of the National Health Interview Survey were analyzed. Logistic regression models predicted self-reported diabetes. The roles of education, income, body mass index (BMI), smoking, and duration of US residence were explored.

RESULTS

Compared to the US-born, foreign-born blacks had significantly lower reported diabetes prevalence (8.94% vs. 11.84%) and diabetes odds ratio [OR: 0.75; 95% confidence interval (CI): 0.62, 0.89], adjusting for socio-demographic characteristics. Further inclusion of education, income, household size, and smoking did not appreciably change the OR (0.77; 95% CI: 0.61, 0.86). Including an adjustment for BMI entirely eliminated the foreign-born advantage (OR 0.93; 95% CI: 0.78, 1.11). The foreign-born from the Caribbean/Americas had similar diabetes odds compared to the African-born. Among the foreign-born, an increased duration of US residence was associated with a higher diabetes odds, but these associations did not reach statistical significance (p > 0.05).

CONCLUSION

The healthy immigrant advantage extended to diabetes among US blacks, a finding that is explained by lower levels of overweight/obesity among the foreign-born compared to the US-born. Nonetheless, more than 71.4% of the foreign-born were overweight or obese. Understanding the mechanisms through which exposure to the US environment leads to higher obesity and diabetes risk may aid prevention efforts for the rapidly growing foreign-born black subpopulation.
