Trajectories of Informal Caregiving to the Oldest-old: A One-year Follow-up Study.

This study aimed to analyze caregivers and care recipients' health characteristics and caregiving context changes during a one-year follow-up. A total of 204 informal caregivers and oldest-old care recipients ( ≥ 80 years) were assessed on two occasions, 12 months apart. Information was retrieved on the dyad's sociodemographic profile, caregiver's health/caregiving outcomes, care recipients' dependency level, and caregiving context. Descriptive analysis was performed for all variables and comparisons between the two moments using paired t tests or McNemar tests. Caregiving hours, caregiver burden, and negative aspects of caregiving got significantly worse over one year. The number of unmet needs, in-home services utilization, and self-perception of mental health improved. Care recipients declined in their functional and health status and on their cognitive performance. This study provides information about caregiving trajectory changes over one year and stresses a probable caregiver adaptation even when facing increasing caregiving demands.
