Objective: To compare sociodemographic characteristics, physical funct
ion, and cognition of Mexican American and non-Hispanic white nursing
home residents. Design and Setting: Cross-sectional survey of resident
s in eight proprietary nursing homes and one Veterans Affairs nursing
home in San Antonio, Texas. Subjects: Residents with lengths of stay g
reater than or equal to 90 days. Measurements: Sociodemographic charac
teristics, residence prior to admission, and dependency in activities
of daily living (ADL) were abstracted from the medical record. The Fol
stein Mini-Mental State Examination (MMSE) was administered in the res
ident's self-selected language to a subset of residents. Main Results:
There were 1160 participants, 261 Mexican American (23%) and 899 non-
Hispanic white residents (77%). Mexican Americans were younger (77.1 v
s 80.7 years), more often men (44% vs 30%), less educated (6.2 vs 10.8
years), and more often dependent on Medicaid funding (66% vs 40%) tha
n non-Hispanic whites. Mexican Americans were less independent in feed
ing (34% vs 49%), transfers (18% vs 30%), toileting (19% vs 29%), and
dressing (12% vs 19%). Mean MMSE scores were different in Mexican Amer
icans and non-Hispanic whites (8.93 vs 11.85), and this difference rem
ained significant after adjustment for age and education (P = 0.04). A
DL function was strongly associated with MMSE (P = 0.0001) and less st
rongly associated with ethnicity (P = 0.056) in multiple regression an
alysis. Conclusions: This study provides the strongest evidence to dat
e that Mexican American nursing home residents are more cognitively an
d functionally impaired than non-Hispanic white residents. Further stu
dies should explore whether medical conditions, selection and referral
patterns or cultural factors explain functional differences between M
exican American and non-Hispanic white nursing home residents.
