In high-income contexts, these increases have coincided with a compression of disability to later ages. However, little evidence on trends in disability-free LE (DFLE) exist from Mexico or elsewhere in Latin America.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Using data from the Mexican Health and Aging Study, we compare changes in LE and DFLE in ages 50\u201359, 60\u201369 and 70\u201379 using birth-cohort-specific multistate lifetable models across successive 10-year birth cohorts. Disability was measured using the Katz activities of daily living (ADL) index, and limitation was measured using a seven-item questionnaire on physical functioning.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Overall, Mexican adults born in 1953\u20131962 lived 0.87 (p&lt;0.001) fewer active years between ages 50 and 59 than individuals born in 1942\u20131951, a difference comprised of a 0.54-year (p&lt;0.001) increase in physically limited LE and a 0.27-year (p&lt;0.001) increase in ADL-disabled LE. Active LE declined by 1.13 (p&lt;0.001) years in ages 60\u201369, and by 0.93 (p&lt;0.001) years in ages 70\u201379, across successive 10-year birth cohorts. No substantial changes in total LE were seen in any age group, and the magnitude of the expansion of disability was larger in females than in males.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Our results indicate that more recently born cohorts of Mexican adults are spending more years of life with physical limitations and disabilities.
