Total time in secondary drinking (in minutes)


SED_DRINK is a 5-digit numeric variable reported in minutes.
99996 = Refused
99997 = Don't know
99999 = NIU (Not in Universe)


SED_DRINK is the sum of all time during the diary day that the respondent spent in secondary drinking. Secondary drinking is drinking that occurred during a primary activity.

Secondary drinking cannot occur during the following primary activities: 010101 (sleeping), 050202 (eating and drinking as part of job), 110101 (eating and drinking), 110199 (eating and drinking, n.e.c.), and 119999 (eating and drinking, n.e.c.).

Researchers may also want to use SED_EAT, which reports the total amount of time in secondary eating. However, users should keep in mind that SED_EAT and SED_DRINK should not be added to create a total of secondary time in eating and drinking as there may be some overlap in specific episodes of secondary eating and drinking (see additional documentation). Researchers may also want to use the secondary eating and drinking filter in the extract builder, or use the total amount of time in primary eating and drinking (PED).

Total time in secondary drinking was calculated based on information collected during the Eating and Health Module of the ATUS interview. Analyses that include SED_DRINK should use EHWT as the weight.


This variable is only available as part of the Eating and Health Module from 2006 to 2008. It was dropped from the module when it was fielded again in 2014 to 2016.

In October 2006, an "all day" option was added for secondary drinking. For respondents who reported "all day," the secondary drinking activity duration is equivalent to the duration of the primary activity. Secondary drinking is not allowed during a small number of primary activities, including sleeping (010101), primary eating and drinking (110101) eating and drinking, n.e.c. (110199, 119999), and eating and drinking as part of job (050202).

Respondents were able to report "all day" prior to October 2006, and the mean duration of secondary drinking increased. The percentage of respondents reporting any secondary drinking remained fairly level over 2007, however, the percentage of those respondents reporting any secondary drinking that indicated a duration of "all day" increased through the latter half of 2007. No internal consistency issues exist for 2006 and 2007. Pooling 2006 and 2007 data should take the skewness of the data into account.
