Abstract

This population-based case-control analysis investigated the association between osteoporosis and prior urinary calculus (UC) in Taiwan. We succeeded in detecting an association between osteoporosis and prior UC (adjusted odds ratio = 1.66). This association was consistent and significant regardless of stone location. Introduction: UC has been demonstrated to be a risk factor for osteoporotic fractures, but no studies to date have directly investigated the association between UC and osteoporosis. This case-control analysis aimed to investigate the association of osteoporosis with prior UC using a population-based dataset in Taiwan. Methods: We first identified 39,840 cases ≥40 years who received their first-time diagnosis of osteoporosis between 2002 and 2009 and then randomly selected 79,680 controls. We used conditional logistic regression analyses to compute the odds ratio (OR) and the corresponding 95 % confidence interval (CI) for having been previously diagnosed with UC between cases and controls. Results: The OR of having been previously diagnosed with UC for patients with osteoporosis was 1.66 (95 % CI = 1.59-1.73) when compared to controls after adjusting for geographic location, urbanization level, type I diabetes mellitus, coronary heart disease, hyperlipidemia, rheumatoid arthritis, stroke, renal disease, Parkinson's disease, hyperthyroidism, chronic hepatopathy, Cushing's syndrome, malabsorption, gastrectomy, obesity, and alcohol abuse/alcohol dependence syndrome. The results consistently showed that osteoporosis was significantly associated with a previous diagnosis of UC regardless of stone location; the adjusted ORs of prior kidney calculus, ureter calculus, bladder calculus, and unspecified calculus when compared to controls were 1.71 (95 % CI = 1.61-1.81), 1.60 (95 % CI = 1.47-1.74), 1.59 (95 % CI = 1.23-2.04), and 1.69 (95 % CI = 1.59-1.80), respectively. Conclusions: This study succeeded in detecting an association between osteoporosis and prior UC. In addition, our findings were consistent and significant regardless of stone location.
