Description
For sample adults, DIETDYR reports if they had been told by a doctor or health professional to reduce the amount of fat or calories in their diet, during the past 12 months.
In 2016 and 2017, 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). Beginning in 2020, this variable is part of the Diabetes Prevention section and is sponsored by NCCDPHP. Please see ACTNOWINC for all variables collected in the section.
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.
