Factors Associated with the Deterioration of Intrinsic Capacity among Older Adults in Mexico and Colombia

Abstract

Background: Intrinsic capacity (IC) is defined as “all the physical and mental attributes possessed by the older person.” This concept has gained momentum in recent years because it provides in-sights into the changes in the functional capacity of individuals during their life. This study examined common factors associated with IC decline among older adults in Mexico and Colombia. Methods: This cross-sectional, correlational study included 348 community-dwelling older adults. Sociodemographic, clinical, and family conditions were assessed as possible associated factors, and IC was analyzed across five domains: cognitive, locomotor, psychological, vitality (malnutrition through deficiency and excess), and sensory (visual and auditory). Parametric and non-parametric statistical analyses were performed. Results: The common factors associated with impairment according to domain were family dysfunctionality (cognitive domain); myocar-dial infarction, family dysfunctionality, age >80 years, home occupation, and not having a partner (locomotor domain); dysfunctional family and risk of falls (psychological domain); age >80 years and not having a partner (malnutrition by deficiency domain); age 60–79 years, walking <7,500 steps/day, and peripheral vascular disease (malnutrition by excess domain); risk of falling and being female (visual sensory domain); risk of falling (auditory sensory domain); and dysfunctional family and risk of falling (total intrinsic capacity). Conclusion: Both populations had common so-ciodemographic, clinical, and familial factors that directly affected total IC stocks and their do-mains.
