Abstract
Ambient air pollution has been associated with bone damage. However, no studies have evaluated the metabolomic response to air pollutants and its potential influence on bone health in postmenopausal women. We analyzed data from Women's Health Initiative (WHI) participants with plasma samples. Whole-body, TH, FN, and spine BMD were determined using DXA at enrollment and follow-up visits (years 1, 3, 6, and 9 visits; Y1, Y3, Y6, Y9, respectively). Geocoded, participant address-specific, daily particulate matter nitrogen oxide (NO), nitrogen dioxide (NO2), particulate matter ≤10 μm (PM10), and sulfur dioxide (SO2) concentrations were averaged over 1-, 3-, and 5-yr periods before plasma sampling for metabolomic assessments (at baseline and Y1 visit). The averages were then integrated using masked WHI participant identifiers. Statistical analyses included multivariable-adjusted linear mixed models, pathway analyses, and mediation modeling. At all averaging periods, NO, NO2, and SO2, but not PM10, were associated with taurine, inosine, and C38:4 phosphatidylethanolamine (PE). We found a partial potential mediation of C38:4 PE in the association between 1-yr average NO and LS BMD (p-value: .032). This is the first study suggesting phospholipids may partially mediate air pollution-related bone damage in postmenopausal women.
期刊介绍:
The Journal of Bone and Mineral Research (JBMR) publishes highly impactful original manuscripts, reviews, and special articles on basic, translational and clinical investigations relevant to the musculoskeletal system and mineral metabolism. Specifically, the journal is interested in original research on the biology and physiology of skeletal tissues, interdisciplinary research spanning the musculoskeletal and other systems, including but not limited to immunology, hematology, energy metabolism, cancer biology, and neurology, and systems biology topics using large scale “-omics” approaches. The journal welcomes clinical research on the pathophysiology, treatment and prevention of osteoporosis and fractures, as well as sarcopenia, disorders of bone and mineral metabolism, and rare or genetically determined bone diseases.
