Codes and Frequencies
For sample adults who completed a set of questions on bowel functions and who have not had a colostomy, BMYRSTRAIN reports how often in the past 12 months their bowel movements have been accompanied by straining to move bowels.
BMYRSTRAIN is part of a supplement on Digestive Disorders initiated in 1989 which had 3 sections. The first asked about specific conditions such as gallstones, ulcers, or colon or bowel conditions (such as BOWELFUNEV, ever had a functional bowel). The second asked about abdominal pain (such as ABPAIN3XYR, had abdominal pain 3 or more times, past 12 months). The third was on normative bowel functions (such as ABGASTRUBYR, had trouble with abdominal gas in the past 12 months). For related variables and more information, please use the IPUMS NHIS search function and drop-down menus, or see the variables listed above.
