The Pennsylvania State University, University Park, Massachusetts, United States  \nThis study investigates the intricate relationships between physical activity, pain, and subjective memory complaints (SMCs) among older adults using data from the 2020 Health and Retirement Study. The primary aims were to examine the association between physical activity and SMCs, evaluate the independent contribution of pain to SMCs, and explore the potential moderating role of pain in the relationship between physical activity and SMCs. Results from linear regression models indicated that the associations of pain and physical activity with SMCs were significant in unadjusted analyses but became non-significant after controlling for covariates, suggesting that self-rated health and depression may mediate these relationships. Stratified analyses further confirmed these findings, showing that physical activity did not significantly predict SMCs in either pain-stratified group. Interaction terms between physical activity and pain were not significant, indicating no moderating effect of pain on the physical activity-SMCs relationship. These results emphasize the importance of promoting physical activity and managing pain to support cognitive health in older adults, and the need for further research to elucidate underlying mechanismsand mediating roles of self-rated health and depression.","cbCaio1XhRBqlqTj","https://ap.wps.com/l/cbCaio1XhRBqlqTj","pdf",46750,"English","# Abstract\n## Study aims\n## Methods and models\n## Key findings\n## Implications and future research","[{\"question\":\"What is the main research focus of this study?\",\"answer\":\"The study focuses on the relationships between physical activity, pain, and subjective memory complaints (SMCs) in older adults, using data from the 2020 Health and Retirement Study.\"},{\"question\":\"What do the regression results show about pain and physical activity?\",\"answer\":\"Associations between pain, physical activity, and SMCs are significant in unadjusted analyses, but they become non-significant after controlling for covariates.\"},{\"question\":\"Does pain moderate the effect of physical activity on subjective memory complaints?\",\"answer\":\"No. Interaction terms between physical activity and pain are not significant, and stratified analyses show physical activity does not significantly predict SMCs within pain groups.\"}]","PAIN, PHYSICAL ACTIVITY, AND SUBJECTIVE MEMORY COMPLAINTS: EVIDENCE FROM THE HEALTH AND RETIREMENT STUDY | PDF",1790640239]
