Anxiety trajectories in the second half of life: Genetic and environmental contributions over age.

ABSTRACT: Clinically significant anxiety symptoms are prevalent among the elderly, yet knowledge about the longitudinal course of anxiety symptoms in later life remains scarce. The goals of this study were to (a) characterize age trajectories of state anxiety symptoms in the second half of life, and (b) estimate genetic and environmental contributions to individual differences in the age trajectory of state anxiety. This study was based on data from 1,482 participants in the Swedish Adoption/Twin Study of Aging who were aged 50 and older at their first occasion (512 complete twin pairs, 458 singletons) and had up to 6 measurement occasions spanning 11 years. Consistent with life span developmental theories of age-related emotional change, anxiety symptom levels declined during the transition from mi
