ANYLMT is a summary measure of whether a person has any IADL, ADL, functional, or activity limitations. ANYLMT is constructed by AHRQ staff based on round-level information. The rounds in which information about limitations is collected changes over time, as noted in more detail under the Comparability tab.
ANYLMT is constructed from round-level component variables (not currently available in IPUMS MEPS) measuring IADLs, ADLs, work limitations, and activity limitations (in all years), and limitations in seeing and/or hearing (from 1996-2012 and 2017 forward). If any of these components were coded "Yes," then ANYLMT is coded as "Yes." If all components were coded "No," then ANYLMT is coded as "No." If all components were coded as "Not in Universe", then ANYLMT was also coded as "Not in Universe." If some components were coded as "No" and others had missing value codes, ANYLMT was coded as "Unknown-not ascertained."
Codes and Frequencies
Changes in the construction of ANYLMT and data collection affect comparability over time.
ANYLMT is completely comparable for the years 1996 to 2012. Between 1997 and 2012, ANYLMT uses information on IADL, ADL, functional, activity, or sensory limitations collected in Rounds 1, 2, and 3 for people in their first year of data collection and Rounds 3, 4, and 5 for people in their second year of data collection. In 1996, ANYLMT uses information on IADL, ADL, functional, activity, or sensory limitations collected in Rounds 1 and 2 of 1996.
Between 2013 and 2016, ANYLMT is constructed from fewer rounds of data and, more significantly for comparability across time, ANYLMT no longer uses information about limitations in hearing or sight. During this period, ANYLMT uses information on IADL, ADL, functional, or activity limitations collected during Rounds 1, 3, and 5. These differences limit comparability between the 1996-2012 and 2013-2016 periods.
Beginning in 2017, the Health Status (HE) section was no longer asked in Round 5, and AHRQ therefore no longer uses data collected from Round 5 in the construction of ANYLMT. Limitations on hearing and seeing were reintroduced as components used to construct ANYLMT in 2017. The 2017 and later values for ANYLMT are composed of information on IADL, ADL, functional, or activity limitations collected during Rounds 1 and 3 and information on difficulty hearing or seeing collected in Rounds 2 and 4. The removal of Round 5 data collection caused a noticeable increase in the number of cases coded as "NIU" compared to years prior to 2017 because respondents had one fewer opportunity to provide information (see Construction of ANYLMT on the Description tab).
