From Occupational Exposure to Bone Fragility: Toward Precision Occupational Medicine in Osteoporosis Prevention
Abstract
Background: : /Objectives: Osteoporosis is a major cause of skeletal fragility, yet occupational determinants of bone health remain comparatively underrecognized in clinical and occupational medicine. This review aimed to critically evaluate the relationships between occupational exposures and skeletal health, examine the biological mechanisms potentially linking workplace conditions to bone remodeling, and explore how occupational information could contribute to individualized osteoporosis risk assessment and prevention.
Methods:: A structured literature search was conducted focusing primarily on studies published between 2020 and June 2026, supplemented by relevant earlier landmark studies. Evidence concerning shift and night work, circadian and sleep disruption, indoor work and sunlight exposure, occupational physical activity and sedentary behavior, psychosocial stress, and selected chemical and environmental exposures was synthesized together with current approaches to osteoporosis diagnosis and fracture-risk assessment.
Results:: The available evidence suggests that night and rotating shift work, circadian disruption, limited daylight exposure, altered mechanical loading, and selected industrial exposures may be associated with changes in bone turnover, bone mineral density, osteoporosis, or skeletal fragility. Potential mechanisms converge on circadian and endocrine regulation, vitamin D–mineral homeostasis, inflammatory and oxidative pathways, RANK/RANKL/OPG…
