Codes and Frequencies
For persons who had at least one poisoning episode in the past 3 months, POISON3MONO reports the total number of poisoning episodes a person had in the past 3 months.
POISON3MONO is a person-level variable and is derived from corresponding poisoning episode-level data.
POISON3MONO is part of a series of variables initiated in 1997 that systematically report persons' injuries and poisonings, the cause, what the person was doing while sustaining the injury or poisoning, and where she/he was at the time of the injury or poisoning. For related variables and additional information, please see the User note on Injuries and Poisonings or use the IPUMS NHIS search function and drop-down menus.
Prior to 2000, persons were asked about injuries and poisonings separately; in 2000, these categories were combined and persons were asked about the causes, activities, and locations related to injury and poisoning episodes at the same time. Because of this combination, the variable was only available for 1997 to 1999. After that, the number of poisoning episodes a person had can be determined by using INJCAUSPOIN, which reports the number of injuries caused by poisoning that a person experienced in the past 3 months. For greater detail on these changes, please see the User Note on Injuries and Poisonings .
