Dr. Zimmer’s recent article “Persistent, Consistent, and Extensive: The Trend of Increasing Pain Prevalence in Older Americans“, co-authored with Dr. Anna Zajacova, has now been published in the Journal of Gerontology: Social Sciences. This article sets to assess trends in pain prevalence from 1992 to 2014 among older U.S. adults and by major population subgroups, and test whether the trends can be explained by changes in population composition.
