Patients' sex, age, body mass index (BMI), comorbidities and treatments were collected from their medical records after they had given written informed consent.ResultsConsidering a least significant change (LSC) of 4.2%, neither comorbidity nor multimorbidity was statistically significantly associated with a reduction in BMD in any of the bone regions studied. However, binary logistic regression analyses adjusted for sex, age, BMI and treatments showed that nephrolithiasis (p = 0.044) and coronary heart disease (p = 0.026) were statistically significantly associated with a reduction in total hip T-score and that hypertension (p = 0.049) and coronary heart disease (p = 0.01) were statistically significantly associated with a reduction in total hip Z-score.ConclusionDespite comorbidity and multimorbidity, patients with osteoporosis are mostly well protected by anti-osteoporotic treatment in daily clinical practice. However, nephrolithiasis, hypertension, and coronary heart disease can influence the response to prescribed anti-osteoporotic treatment, especially at the total hip level.
