Fruit and vegetable intake in African Americans income and store characteristics.

BACKGROUND: The purpose of this study was to examine whether the characteristics of retail food stores where African-American women shopped mediated the association between their income and intake of fruits and vegetables. Food store characteristics included store type (supermarket, specialty store, limited assortment store, independent grocer), store location (suburbs, city of Detroit), and perceptions of the selection/quality and affordability of fresh produce for sale. METHODS: The analysis drew upon data from a probability sample of 266 African-American women living in 2001 in eastside Detroit, which had no supermarkets. Structural equation modeling was used to calculate a path model of direct and indirect effects. RESULTS: Women shopping at supermarkets and specialty stores consumed fruit and vegetables more often, on average, than those shopping at independent grocers. More positive perceptions of the selection/quality, but not affordability, of fresh produce at the retail outlet where they shopped was positively associated with intake, independent of store type and location as well as age, per capita income, and years of education. The results suggested an indirect association between income and fruit and vegetable intake; women with higher per capita incomes were more likely to shop at supermarkets than at other grocers, which in turn was associated with intake. CONCLUSIONS: Previous studies have shown that few supermarkets are located in the city of Detroit, a symptom of economic divestment over the past several decades. Results of this study suggest this may have negative implications for dietary quality, particularly among lower-income women.

Healthy eating and exercising to reduce diabetes: exploring the potential of social determinants of health frameworks within the context of community-based participatory diabetes prevention.

OBJECTIVES: We examined a community-based participatory diabetes intervention to identify facilitators of and barriers to sustained community efforts to address social factors that contribute to health. METHODS: We conducted a case study description and analysis of the Healthy Eating and Exercising to Reduce Diabetes project in the theoretical context of a conceptual model of social determinants of health. RESULTS: We identified several barriers to and facilitators of analysis of social determinants of a community-identified disease priority (in this case, diabetes). Barriers included prevailing conceptual models, which emphasize health behavioral and biomedical paradigms that exclude social determinants of health. Facilitating factors included (1) opportunities to link individual health concerns to social contexts and (2) availability of support from diverse partners with a range of complementary resources. CONCLUSIONS: Partnerships that offer community members tangible resources with which to manage existing health concerns and that integrate an analysis of social determinants of health can facilitate sustained engagement of community members and health professionals in multilevel efforts to address health disparities.

Evaluating a problem-based empowerment program for African Americans with diabetes: results of a randomized controlled trial.

OBJECTIVE: The objective of this study was to evaluate the impact of a problem-based empowerment patient education program specifically tailored for urban African Americans with type 2 diabetes. RESEARCH DESIGN AND METHODS: The study used a randomized controlled trial (RCT) pretest/post-test design with repeated measures. Patients were randomly assigned to either a six-week intervention group or a six-week wait-listed control group. After completing the six sessions, patients were invited to participate in one of two follow-up conditions; attend a monthly support group or receive a monthly phone call from a nurse. Assessment measures included HbA1C, lipids, blood pressure, weight, self-management behavior and psychosocial adaptation. RESULTS: Both control and intervention patients showed a broad array of small-to-modest positive changes during the six-week RCT. These gains were maintained or improved upon during the one-year follow-up period. For patients in the two follow-up conditions, a positive correlation was seen between the number of follow-up contacts and their one-year HbA1C values. CONCLUSIONS: We believe that results of this study can be attributed to volunteer bias, study effects (ie, providing study data on several occasions to patients and their physicians during the one-year study period), and impact of the interventions. However, the study design does not allow us to examine the relative impact of these three factors on the patient improvements seen over the one-year study period.

Informal diabetes education: impact on self-management and blood glucose control.

PURPOSE: The purpose of this study was to determine if participation in screening clinics to detect and treat diabetes-related eye disease also led to informal patient learning that had an impact on self-management behavior and blood glucose control. METHODS: To evaluate the evidence for patient learning over time, the data of patients who returned as advised for 2 subsequent annual diabetes disease screenings were analyzed. Evaluation measures included medication use, self-management behavior, and hemoglobin A1c (A1C). RESULTS: During the 2-year study period, the use of insulin increased by 37% at the first exam, 43% at the second exam, and 42% at the third exam (P = .02). No significant changes were found in the use of oral medication. Glucose self-monitoring also increased by 61% at the first exam, 71% at the second exam, and 76% at the third exam (P < .01). Mean A1C values for returning participants declined by 9.2% at the first exam, 8.9% at the second exam, and 8.6% at the third exam (P = .03). CONCLUSIONS: The screening clinics had an educational impact associated with behavior change (improved self-management and glucose control) even though the clinics were not intended to produce such change. Therefore, caregivers should consider that patient learning can and should be part of every diabetes care encounter.

Implementing an empowerment-based diabetes self-management education program.

Diabetes educators are challenged to develop culturally appropriate, integrated, behaviorally based, effective education programs. This article describes the intervention used in a problem-based educational program for urban African Americans with diabetes. The intervention consisted of six 2-hour, weekly group educational and data collection sessions. No lectures were used, and the content was determined by participants' questions and concerns. Culturally tailored written educational materials were also provided.

Developing a new generation of ongoing: Diabetes self-management support interventions: a preliminary report.

PURPOSE: The study examined the feasibility, acceptability, and potential impact of an innovative, community-based, ongoing self-management intervention aimed at enhancing and sustaining self-care behaviors over the long term among urban African Americans with type 2 diabetes. METHODS: Sixty-two African American men and women completed the study. Participants were invited to attend 24 weekly, consecutive, diabetes self-management support/ education groups. The flow of the weekly group sessions was guided by questions and concerns of the patients. Baseline and 6-month follow-up metabolic functioning, lipid profiles, cardiovascular functioning, and self-care behaviors were assessed. RESULTS: Ninety percent (n = 56) of the sample attended at least 1 session; 40% attended at least 12 or more sessions. Paired t tests found significant improvements in body mass index (P < .001), total cholesterol (P < .01), high-density lipoprotein (P < .05), and low-density lipoprotein (P < .001). Significant increases were also found for self-care behaviors (P < .05). CONCLUSIONS: Preliminary evidence suggests that participation in this weekly problem-based, self-management support intervention can yield diabetes-related health benefits.

A study of certified diabetes educators: influences and barriers.

PURPOSE: There were 2 related goals for this study. The first purpose was to describe the structure (type, staffing, and number of educational sessions provided), process (preferred learning approaches), and outcome measures commonly used to provide patient education. The second purpose was to identify the influences, resources, and constraints that affect and alter the attitudes and practices of diabetes educators. METHODS: A 30-item questionnaire that addressed 4 areas--demographics, practice characteristics, education program structure, and educational processes--was mailed to a sample of American Association of Diabetes Educators members. Three hundred sixty-one registered nurse and registered dietician certified diabetes educators completed the questionnaire and were included in the final analysis. RESULTS: This survey indicated that this group of certified diabetes educators has incorporated new research findings and innovative teaching methods into their practices. They experience few barriers and tend to make changes in their attitudes and practices based on scientific and experiential evidence. The 3 most highly rated influences on these changes were related to patient responses to their teaching, followed by continuing education conferences and new research findings. CONCLUSIONS: Based on these findings, providing continuing education that first and foremost incorporates experience-based examples of effective strategies supported by research published in professional journals appears to have the most influence on the practice of educators.
