DITIMPORT reports how important the respondent's use of a special diet had been to his/her health and well-being.

For information about the full range of variables related to special diets, including definitions, see DITATKINYR. For related variables and more information, please see TABDOM1, or use the search function or IPUMS NHIS drop-down menus.


Prior to 2012, sample adults who used at least one special diet for two weeks or more for health reasons in the past 12 months were asked about the importance of and their reasons for using the special diet.

Beginning in 2012, adults and children were instead asked to select three of sixteen therapies that were most important and only asked the series of questions related to treating health problems, symptoms, or conditions about these top three therapies, as well as questions about reasons for and the importance of use of the top three therapies. Persons who did not include a special diet among their top three CAM therapies did not answer follow up questions for this therapy beginning in 2012 and are reported as responding "no".


  • 2002: Sample adults age 18+ who have used at least one of these special diets for two weeks or more for health reasons during the past 12 months.
  • 2012: Sample adults age 18+ and sample children ages 4-17 who have reported having at least one top CAM therapy and using this therapy to treat a specific health problem or condition.
