Among them, the role of basophils remains poorly understood. This study investigated the association between peripheral blood basophil count and lumbar spine bone mineral density (BMD) in an East Asian adult population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective analysis was conducted on 200 adults undergoing health check-ups and lumbar dual-energy X-ray absorptiometry. Basophil count and other hematologic and biochemical parameters were correlated with lumbar spine T-scores using multivariate regression.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Basophil count showed no significant correlation with T-scores in the overall cohort (r = 0.06, p = 0.4261). However, a weak inverse trend was noted in participants with BMI \u2265 27. In contrast, GPT and creatinine were significantly associated with BMD, with alanine aminotransferase (GPT) emerging as a strong independent predictor (\u03b2 = 0.61, p &amp;lt; 0.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Basophil count does not appear to be a reliable biomarker for BMD in the general population. However, findings in the higher-BMI subgroup suggest a potential link that warrants further investigation. GPT may hold greater utility as a surrogate marker for bone health in clinical screening. The present findings also highlight the value of publishing negative results and underscore the need for future research in larger and more diverse cohorts.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fendo.2025.1643760","type":"journal-article","created":{"date-parts":[[2025,9,4]],"date-time":"2025-09-04T10:20:46Z","timestamp":1756981246000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Re-evaluating
