Type II diabetes prevalence and risk factors in Los Angeles Japanese

Research has indicated that Japanese living in the United States exhibit a high prevalence (over 12%) of Type II diabetes, also known as non-insulin dependent diabetes mellitus (NIDDM). Japanese living 1n Japan, however, have an average rate of approximately 3%, which is comparable to that of the overall U.S. rate for NIDDM. These earlier studies have either surveyed just one generation of Japanese [1], or have compared Hiroshima sedentates 1n Japan with descendents of Hiroshima migrants in Hawaii and Los Angeles [2]. The current study surveyed a multigenerational volunteer sample of Japanese all presently residing ln Los Angeles. The aim was to assess the prevalence of Type II diabetes and risk factors other than diet among the generations of Japanese in Los Angeles. The risk factors tested included age, sex, occupation, marital status, body mass index, hypertension, stress and family history of diabetes. A questionnaire with cover letter was designed for this purpose. A total of 255 Volunteer members of 8 local Los Angeles Japanese organizations completed the questionnaires. (See more in text.)
