BACKGROUND AND OBJECTIVES Older adults' health trajectory is often pictured as loss and decline. Recent literature has questioned this assumption. Conceptualizing health as a multidimensional construct, encompassing physical disabilities, functional limitations, chronic diseases, depressive symptoms, memory problems, and self-rated health, we investigated patterns of health trajectories among middle-aged and older adults in the United States. Moreover, we investigated the relationship between self-perceptions of aging (SPAs) and health trajectory patterns. RESEARCH DESIGN AND METHODS We used latent class growth modeling to examine health trajectory patterns, based on longitudinal data with 4 measurement points over a 7-year period from a national sample of 10,212 middle-aged and older adults (aged 51 and older). Multinomial logit models were used to examine how health trajectory patterns were associated with baseline SPA. RESULTS We identified 4 health trajectory patterns: accelerated aging, usual aging, depressed aging, and healthy aging. The full model shows that with each one-unit increase in negative SPA, the odds of belonging to an accelerated aging group, depressed aging group, and usual aging group (vs healthy aging group) increased by 26%, 17%, and 9%, respectively. DISCUSSION AND IMPLICATIONS The combination of health changes across different domains results in health trajectories that cannot be understood as simply a declining process. SPAs are associated with individuals' trajectories of health.
