Description

For sample adults, DIADIAGFAM reports if they have a mother, father, brother, or sister who has ever been told by a doctor or other health professional that they have diabetes or sugar diabetes. This variable includes only blood relatives and does not include step-relatives or those unrelated by blood.

This variable is part of the Sample Adult Diabetes supplement, sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP) in 2016 and 2017 and the NCCDPHP in 2020.

Comparability

While the basic meaning of this variable is completely comparable over time, major questionnaire changes introduced in 2019 may affect comparability with earlier years. The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
