['To examine the relationship between dysglycemia (impaired fasting glucose, impaired glucose tolerance, and diabetes) and acculturation, physical activity, and perceived stress in Arab immigrants in the U.S.', 'In a cross-sectional population-based study, we examined 520 Arab Americans, aged 20-75 years, who were born in the Middle East and immigrated to southeastern Michigan. Dysglycemia was assessed by history and with a 2-h 75-g oral glucose tolerance test. Acculturation, physical activity, and perceived stress were measured with standardized questionnaires.', 'Associations were found between dysglycemia in men and older age at immigration, unemployment, speaking Arabic with friends, being less active in Arabic organizations, more frequent consumption of Arabic food, and less integration into American society. Dysglycemia in women was associated with being raised in rural areas of the Middle East, older age at immigration, longer length of stay in the U.S., not being employed outside the home, less than high school education, not attending Arabic or American schools, and not being able to read Arabic. Among men, older age at immigration, shorter length of stay in the U.S., less activity in Arab organizations, and eating Arabic food were associated with dysglycemia independent of age and BMI. Among women, acculturation was very low and was confounded with age and BMI as powerful risk factors for dysglycemia. No association was found between physical activity, perceived stress, and the risk of dysglycemia in either sex.'] Is lack of acculturation a risk factor for diabetes in arab immigrants in the US?
