Sullivan KJ, et al. - Researchers examined whether birth cohort effects in depression symptoms exist in older adults. From small-town communities in Pennsylvania, 3,227 older adults (average baseline age = 71.6) who were born between 1902 and 1941 were included. The primary predictors in this study were four decade-long birth cohorts: 1902–1911, 1912–1921, 1922–1931, and 1932–1941. Relative to earlier born cohorts of older adults, more recently born cohorts reported fewer depression symptoms, particularly symptoms involving depressed mood and anergia and hopelessness; they were also less likely to report greater 5 or more depression symptoms. These findings may indicate birth cohort trends in compression of medical morbidity and cognitive morbidity.
