Aging populations face health challenges, and volunteering may improve health outcomes. This study investigated
the relationship between volunteering, CD34+ hematopoietic stem cells, and health indicators in older adults.
The sample included 91 participants aged 65 to 75, with 52 reporting prior volunteering involvement. Evaluations
comprised the Geriatric Depression Scale (GDS), Mini-Mental State Examination, Clinical Dementia Rating scale, and
Neuropsychiatric Inventory. Blood analyses measured CD34+ hematopoietic stem cells and CD34+ lymphocytes.
Multiple linear regression assessed variations in CD34+ counts and related metrics among groups, adjusting for
confounding factors. Volunteers exhibited enhanced cognitive functioning and lower depression levels compared to
non-volunteers, as reflected in GDS scores of 4.29 ± 4.18 versus 8.26 ± 5.09 (p < .001). Furthermore, volunteers
had notably elevated CD34+ stem cell and lymphocyte counts, suggesting volunteering positively influences this
health marker. Participation in volunteer activities is linked to improved cognitive abilities, reduced depressive
symptoms, and heightened CD34+ hematopoietic stem cell levels. Findings underscore the potential health benefits
of volunteering for older adults, necessitating further investigation into the mechanisms and enduring effects of
volunteerism on health, with CD34+ cell counts identified as a significant biomarker for cognitive and emotional
health enhancements in this population |
