The authors examined the associations of observed neighborhood (block face) and housing conditions with the incidence of diabetes by using data from 644 subjects in the African-American Health Study (St. Louis area, Missouri). They also investigated five mediating pathways (health behavior, psychosocial, health status, access to medical care, and sociodemographic characteristics) if significant associations were identified. The external appearance of the block the subjects lived on and housing conditions were rated as excellent, good, fair, or poor. Subjects reported about neighborhood desirability. Self-reported diabetes was obtained at baseline and 3 years later. Of 644 subjects without self-reported diabetes, 10.3% reported having diabetes at the 3-year follow-up. Every housing condition rated as fair-poor was associated with an increased risk Correspondence to Dr. Mario Schootman, Division of Health Behavior Research, Washington University, 4444 Forest Park Boulevard, Box 8504, St. Louis, MO 63108 (mschootm@im.wustl.edu).

No association was found between any of the block face conditions or perceived neighborhood conditions and incident diabetes. The odds ratios for the five housing conditions were unaffected when adjusted for the mediating pathways. Poor housing conditions appear to be an independent contributor to the risk of incident diabetes in urban, middle-aged African Americans.
KeywordsAfrican Americans; aging; diabetes mellitus; housing; questionnaires; residence characteristics Diabetes mellitus is now approaching epidemic proportions (1). In the United States, the prevalence and incidence of diabetes increased dramatically during the past two decades (1) such that diabetes now affects about 20.8 million people or 7 percent of the population (2). The number of individuals with diagnosed diabetes is estimated to triple by the year 2050 (3).African Americans are more likely than Whites to develop diabetes (4). Estimates show that 3.2 million African Americans currently have diabetes (5). The number of African Americans with diabetes is projected to triple by the year 2050, but the number is estimated to only double among Whites (3).While the pathogenesis of diabetes is complex, a number of factors have been identified that increase the risk of the disease. In addition to African-American race, they include increased body mass index, age 45 years or older, physica...
