For sample adults who did not refuse a set of questions on bowel function in 1989, and persons ages 18 and older in the National Health Interview Survey-Disability Survey (NHIS-D) Phase I sample in 1994 and 1995, DIZZYLOTYR reports whether the person had a lot of trouble with dizziness in the past 12 months (1989), or currently has any problem with dizziness that has lasted for at least three months (1994 and 1995).


DIZZYLOTYR was included as part of a supplement on Digestive Disorders initiated in 1989.

In 1994 and 1995 this variable is part of the Disability Supplement (NHIS-D) that collects information on disability. NHIS-D included two household interviews: in Phase I all members of sample families were screened for any indication of disability; in Phase II persons with any indication of disability were followed-up for additional information. Phase I includes sensory, communication, and mobility problems; health conditions; activities of daily living and independent activities of daily living; functional limitations; mental health; services and benefits; special health needs of children; early child development; education; relationship to respondent; and perceived disability. Phase II includes four Disability Followback Survey (DFS) questionnaires: one for children, one for adults, one for elderly persons (69 years of age and over) without any indication of disability (also called the Supplement on Aging or SOA; only in 1994), and one for persons with a history of polio.


Changes in question wording affect comparability between samples the 1989 and 1994/1995 samples.

In 1989, DIZZYLOTYR was included in a list of problems that may have been a lot of trouble for the person in the past year. Interviewers instructed respondents that "a lot of trouble" means that in the past year, the person saw or talked to a doctor or other health professional, took medication more than once, or the problem interfered with the person's life or usual activities.

In 1994 and 1995, a household respondent reported whether the person now has any problem with dizziness that has lasted for at least three months.
