Feasibility of Measuring Hair Glucocorticoids as a Potential Biomarker for Chronic Stress in Older Adults With Intellectual Disabilities

Overall feasibility of measuring HairGCs in older adults with ID was moderate. Feasibility was lower in males, with insufficient hair length/thickness as the main limitation, and higher in participants with moderate ID. HairGC measurement appears most feasible in females and less so in balding males, limiting its broader applicability as a stress measurement tool in an older population.
