Functional limitations among Chilean older adults: the impact of childhood socioeconomic position and employment trajectories

Abstract

Objectives: Based on a life course perspective, we explored the effects of childhood socioeconomic position (SEP) and employment trajectories on functional limitations among older people living in Santiago, Chile. Methods: Data were drawn from a comprehensive and representative life history dataset of persons aged 65-75. We used logistic regression analyses to assess the effects of childhood SEP and employment trajectories on functional limitations, including 3 physical domains. Results: Low childhood SEP and employment trajectories characterized by informal and part-time work negatively affect functional limitations in old age. Both seem to have a direct effect on functional ability. Discussion: The life course approach could enrich the study of functional limitations, helping to better understand how social factors impact older people's functional ability. This, in turn, could help optimize the design of public policies and strategies to reduce the number of years of life dependent on others, thus promoting healthy aging.
