Data were derived from a longitudinal study of a nationally representative sample of Japanese older adults aged 60+ years. We compared two death-year cohorts based on individuals’ year of death (earlier:  \n1987-1999 versus later: 2000-2012) case-matched based on age at death and sex (n = 668 per cohort). Well-being was indicated by life satisfaction and depressive symptoms. Multilevel models found death-year cohort differences in life satisfaction but not depressive symptoms. While the levels of and rates of changes in life satisfaction did not differ across death-year cohorts, the association between physical health and well-being was stronger in the later-deceased cohort. These findings suggest that terminal decline in life satisfaction accelerates in interaction with disease particularly in later cohorts, with those who more recently passed away with high disease load experiencing lower levels of life satisfaction and more rapid declines. These secular trends maybe due to societal advancements in healthcare systems enabling later-born cohorts to be more likely to survive with health declines.","cbCaiuVnIqod20eQ","https://ap.wps.com/l/cbCaiuVnIqod20eQ","pdf",233354,"English","# Background\n## Competing scenarios for secular trends\n# Study Design\n## Pre-registered objectives\n## Sample and cohort comparison\n# Measures\n## Life satisfaction\n## Depressive symptoms\n# Results\n## Cohort differences in life satisfaction\n## Health–well-being associations\n# Interpretation\n## Interaction with disease load\n## Societal healthcare advancements","[{\"question\":\"What was the main purpose of the pre-registered study?\",\"answer\":\"To examine how individuals’ well-being changes in the last years of life and related correlates differ over historical time.\"},{\"question\":\"How were the participants grouped for analysis?\",\"answer\":\"Two death-year cohorts were compared: earlier (1987-1999) versus later (2000-2012), matched by age at death and sex.\"},{\"question\":\"What did the study find about life satisfaction and depressive symptoms?\",\"answer\":\"Death-year cohort differences appeared for life satisfaction, but not for depressive symptoms.\"}]","HISTORICAL CHANGES IN TERMINAL DECLINE IN WELL-BEING AMONG JAPANESE OLDER ADULTS - Pre-registered study on life satisfaction and depressive symptoms | PDF",1790643090]
