ObjectivesThis article seeks to document the progression of disability in a developing country by
implementing a model to examine how this process compares to a developed country.MethodsData come from the Mexican Health and Aging Study (MHAS), including a baseline survey
in 2001 and a follow-up in 2003, and from the U.S. Health and Retirement Study (HRS),
using the 2000 and 2002 waves. An ordinal logistic regression approach is used to
examine a progression of disability that considers (a) no disability, (b) mobility
problems, (c) mobility plus limitations with instrumental activities of daily living,
(d) mobility plus limitations with activities of daily living (ADLs), (e) limitations in
all three areas and (f) death.ResultsIn both data sets, approximately 44% of the sample remained in the same level of
disability at the 2-year follow-up. However, the progression of limitations with two
disabilities differs by gender in the MHAS but is consistent for both men and women in
the HRS.DiscussionOur model reflects the importance of ADLs in the disablement process in Mexico. We
speculate that the difference in lifetime risk profiles and cultural context might be
responsible for the divergence in the progression of disability by gender.
