Description
For sample adults ages 18 and older who have ever had a diagnosis for a swallowing problem that lasted a week or longer, VSLSWCOPD reports whether the respondent's swallowing problem was caused by chronic obstructive pulmonary disease (COPD).
VSLSWCOPD is part of the Adult Voice, Speech and Language Supplement. For related variables and more information, please use the IPUMS NHIS search function and drop-down menus, or see VSLDIAG, which reports on diagnosis, VSLVDAYS, which reports on the problem duration and extent, and VSLVSLPYR, which reports on treatment.
