Are recent cohorts in worse health?

From the abstract:

Our sample is individuals in the Health and Retirement Study who are aged 51 to 54 at baseline and are followed for up to two decades. We find that limitations in most domains have increased for younger cohorts, especially pain and cognitive impairment. People are more impaired in their 50s, where such impairment used to occur in one’s 60s. However, this appears to be a speeding up of impairment more than a long-term increase. Among people in their late 60s, health for later cohorts is similar to health for earlier cohorts. To evaluate the implications of these trends, we simulate the work capacity of adults just before reaching age 65 based on the health status of people at this age and the relationship between health and the labor force outcomes of younger people. Overall health among those age 62 to 64 remains high, despite impairment striking at younger ages. However, among people without high school degrees, less than half are predicted to have the capacity to work full time by age 62 to 64, and over a quarter are predicted to be receiving SSDI.
