About

Anton J.M. de Craen’s research centers on the clinical epidemiology of aging, with a particular focus on how physiological changes—such as declining thyroid function and anemia—shape health outcomes in the oldest old. His landmark work, “Low Thyroid Function and Anemia in Old Age: The Leiden 85‐Plus Study,” published in 2015, investigates the complex interplay between subclinical hypothyroidism and anemia in individuals aged 85 and older. By analyzing data from this unique, population-based cohort, de Craen demonstrated that low thyroid function is independently associated with a higher prevalence of anemia, even after adjusting for common confounders. This finding challenges conventional clinical assumptions and underscores the need for careful diagnostic evaluation in geriatric patients, where overlapping symptoms often obscure underlying causes. Though this specific paper has garnered 9 citations, it represents a critical piece of a larger body of work that has shaped understanding of age-related physiological decline. De Craen’s contributions are particularly valuable for researchers and clinicians working at the intersection of endocrinology and geriatric medicine, offering evidence-based insights that improve diagnostic accuracy and patient care in an increasingly aging population.
