OBJECTIVE -To examine the prevalence of diabetes and glucose intolerance by age and sex in the Arab-American community of Dearborn, Michigan.RESEARCH DESIGN AND METHODS -Participants were randomly selected adult Arab Americans, 20 -75 years of age, from randomly selected households in Dearborn, Michigan. Demographic and anthropometric data were recorded. Glucose tolerance was assessed with 2-h 75-g oral glucose tolerance tests and classified according to 1997 American Diabetes Association and 1998 World Health Organization criteria.RESULTS -A total of 626 eligible adults were selected, and 542 participated (87% response rate). Because prevalence increases with age and the overall response rate for women (328/352; 93%) was higher than that for men (214/274; 78%), prevalence rates were adjusted for age and sex. The overall prevalence of diabetes was 15.5% (95% CI 12.2-18.7%) in women and 20.1% (15.0 -25.2%) in men (P ϭ 0.13). The prevalence of previously diagnosed diabetes was similar to that of undiagnosed diabetes. Impaired glucose tolerance (IGT) and/or impaired fasting glucose (IFG) were present in 16. 8% (12.8 -20.8%) of women and 29.7% (23.4 -35.9%) of men (P ϭ 0.0007). The combined rates of glucose intolerance (diabetes, IGT, and IFG) were 32.3% (27.8 -36.7%) for women and 49.8% (43.1-56.4%) for men (P Ͻ 0.0001). Among younger adults, the prevalence in men was higher than that in women. As expected, subjects with diabetes or IGT/IFG were older and had greater BMI and waist-to-hip ratios than subjects with normal glucose tolerance.CONCLUSIONS -The prevalence of diabetes and glucose intolerance is extremely high among adult Arab Americans in Michigan and represents a major clinical and public health problem. Community-based intervention programs to prevent and treat diabetes are urgently needed.
Diabetes Care 26:308 -313, 2003A rab immigration to the U.S. began in the 1890s but increased in the late 1960s and early 1970s as a result of political instability in the Eastern Mediterranean region. Currently, ϳ2-3 million Arab Americans live in the U.S.Michigan is home to the largest Arab concentration outside the Middle East, and the Arab-American population represents the third largest minority group in Michigan. Approximately 250,000 -300,000 Arab Americans live in the Detroit Metropolitan Area-one-third of them in southwestern Wayne County. This community is young, with a median age of 27 years; is primarily composed of immigrants from rural communities; and is ethnically heterogeneous, with Lebanese Americans representing the largest group. The Arab-American community is characterized by a relatively recent transition to a western lifestyle. Availability and accessibility of heath care are major concerns and linguistic, cultural, social, and financial barriers contribute to the problem.High rates of type 2 diabetes have been observed in Arab populations in the Middle East in areas undergoing rapid economic development (1,2). There are no published representative populationbased studies describing the prevalen...
