Type 2 diabetes and impaired fasting glucose in American Indians aged 5-40 years: the Cherokee diabetes study.

Purpose: To estimate the prevalence of type 2 diabetes and impaired fasting glucose (IFG) and to study several potential risk factors for type 2 diabetes among Oklahoma Cherokees aged 5 to 40 years.

Methods: A random sample of 2205 members of the Cherokee Nation of Oklahoma aged 5 to 40 years was recruited. Demographic, clinical, and laboratory data were collected.

Regional variation in cardiovascular disease risk factors among American Indians and Alaska Natives with diabetes.

Objective: To compare by region risk factors for cardiovascular disease among American Indian populations with diabetes.

Research Design And Methods: Trained providers from 185 federal, urban, and tribally operated facilities reviewed the records from systematic random samples of the patients included in the local diabetes registries in the 1998 Indian Health Service (IHS) Diabetes Care and Outcomes Audit. Selected measures of cardiovascular risk were aggregated by region and adjusted to calculate regional rates for patients <45 years of age (n = 2,595) and those aged > or =45 years (n = 8,294).
