Diets rich in dark-green and orange vegetables have been associated with a reduction in chronic diseases. However, most Americans do not consume the number of daily servings recommended by the 2005 Dietary Guidelines for Americans. An increasing number of studies suggest that changes to the neighborhood food environment may be critical to achieving population-wide improvements in eating. The objective of this study was to examine the relationship between observed neighborhood availability and individual consumption of dark-green and orange vegetables among low- to moderate-income and ethnically diverse adults in Detroit. This study used a cross-sectional design that drew upon a 2002-2003 community survey and 2002 in-person audit of food stores. A total of 919 adults (mean age 46.3 years, 52.2% female) including African Americans (56.7 %), Latinos (22.2%), and whites (18.7%) residing in three Detroit communities participated in the survey. Two-level weighted, hierarchical linear regression was used to analyze the data. On average, survey respondents ate 0.61 daily servings of dark-green and orange vegetables. Residents of neighborhoods with no stores carrying five or more varieties of dark-green and orange vegetables were associated with an average of 0.17 fewer daily servings of these foods compared with residents of neighborhoods with two stores carrying five or more varieties of dark-green and orange vegetables (P=0.047). These findings suggest that living in a neighborhood with multiple opportunities to purchase dark-green and orange vegetables may make an important contribution toward meeting recommended intakes.

Although the importance of culture in shaping individual dietary behaviors is well-documented, cultural food preferences have received limited attention in research on the neighborhood food environment. The purpose of this study was to assess the availability of commonly consumed and culturally specific fruits and vegetables in retail food stores located in majority African-American and Latino neighborhoods in southwest Chicago, IL. A cross-sectional survey of 115 stores (15% grocery stores, 85% convenience/corner stores) in African-American neighborhoods and 110 stores (45% grocery stores, 55% convenience/corner stores) in Latino neighborhoods was conducted between May and August of 2006. χ2 tests were used to assess differences in the availability (presence/ absence) of commonly consumed (n=25) and culturally specific fruits and vegetables for African Americans (n=16 varieties) and Latinos (n=18 varieties). Stores located in neighborhoods in which the majority of residents were African American or Latino were more likely to carry fresh fruits and vegetables that were culturally relevant to the dominant group. For example, grocery stores located in Latino neighborhoods were more likely to carry chayote (82.0% vs 17.6%, P<0.05), whereas grocery stores located in African-American neighborhoods were more likely to carry black-eyed peas (52.9% vs 20%, P<0.05). Most stores, however, carried fewer than 50% of commonly consumed or culturally specific fruits and vegetables. Findings from this study highlight that limited availability of culturally specific as well as commonly consumed fruits and vegetables in the neighborhood may be a barrier to fruit and vegetable consumption among African Americans and Latinos.

OBJECTIVE: To provide information on the characteristics of eating disorders based on nationally representative samples of African American and Caribbean Black adults and adolescents. METHOD: Conducted between 2001 and 2003 the National Survey of American Life (NSAL) interviewed adults (n = 5,191) and adolescents (n = 1,170) in their homes. Professionally trained interviewers used the WMH Composite International Diagnostic Interview (WMH-CIDI-WHO Organization 2004-modified) to assess DSM-IV TR eating disorders. RESULTS: Anorexia was the rarest eating disorder among African American adults and adolescents, with age of onset for adults in mid adolescence. No 12-month case of anorexia was found among Caribbean Black adults. Binge eating was the most prevalent eating disorder among adults and adolescents. Persistence of disorders was lowest for anorexia and highest for binge eating disorder among adults. CONCLUSION: Prevalence of eating disorders within the U.S. Black population varies by type of disorder, age cohort, gender, and ethnic group among adults, and by type of disorder among adolescents. Clinicians need preparation and training to recognize and treat eating disorders in ethnically-diverse patient populations. (c) 2007 by Wiley Periodicals, Inc.
