Parental history and early-onset type 2 diabetes in African Americans and Latinos in Chicago.

Abstract

OBJECTIVE:

To examine the role of parental diabetes mellitus (DM) in the development of type 2 DM among children and adolescents from high-risk ethnic groups.

STUDY DESIGN:

A population-based dataset of insulin-treated diabetes among African American and Latino children <18 years old yielded 243 cases who completed an interview. A subset with features of type 2 DM was identified (n = 44) using one or more criteria: stopping insulin therapy; using oral hypoglycemic agents; acanthosis nigricans; polycystic ovary syndrome; denoted "atypical" or "type 2" by a physician.

RESULTS:

Of all the patients, 76% had no known diabetic parent; 7% had father only; 15% had mother only; and 2.5% had two diabetic parents. Parental DM was more likely in type 2 than in type 1 children (only paternal, 15.9% vs 5.5%, P <.02; only maternal, 38.6% vs 9.5%, P <.01; or both, 6.8% vs 1.5%, P <.01).

CONCLUSION:

A positive parental history of DM appears to be more strongly related to childhood type 2 than to type 1 DM. Whether this is a reflection of genetic or behavioral factors is yet unclear.
