Disease onset is insidious and consequently typically burdened by diagnostic delay. A longer diagnostic delay induces more frequently cardiovascular, respiratory, metabolic, neuropsychiatric and musculoskeletal comorbidities. No data are available on the effect of diagnostic delay on skeletal fragility. We aimed to evaluate the effect of diagnostic delay on the frequency of incident and prevalent of vertebral fractures (i-VFs and p-VFs) in a large cohort of acromegaly patients.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Patients and methods<\/jats:title>\n                <jats:p>A longitudinal, retrospective and multicenter study was conducted on 172 acromegaly patients.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Median diagnostic delay and duration of follow-up were respectively 10\u00a0years (IQR: 6) and 10\u00a0years (IQR: 8). P-VFs were observed in 18.6% and i-VFs occurred in 34.3% of patients. The median estimated diagnostic delay was longer in patients with i-VFs (median: 11\u00a0years, IQR: 3), in comparison to those without i-VFs (median: 8\u00a0years, IQR: 7; p\u2009=\u20090.02). Age at acromegaly diagnosis and at last follow-up were higher in patients with i-VFs, with respect to those without i-VFs. The age at acromegaly diagnosis was positively associated with the diagnostic delay (p\u2009&lt;\u20090.001, r\u2009=\u20090.216). A longer history of active acromegaly was associated with a high frequency of i-VFs (p\u2009=\u20090.03).
