BackgroundBone complications are common in patients with thalassemia.ObjectivesTo assess risk factors for osteoporosis in patients with nonmajor thalassemia and its prevalence in randomly selected adult patients in Thailand.Patients and methodsWe included 190 adult patients (58 men and 132 women) with thalassemia intermedia or minor in this cross-sectional study. Patients with untreated hypogonadism, untreated hypothyroidism, menopause, and with a history of treatment with medications that have effects on skeletal or bone metabolism were excluded. Bone mass density (BMD) of the femoral neck was measured by calibrated dual-energy X-ray absorptiometry. Independent factors likely to be associated with osteoporosis were determined and included in the analysis to ascertain possible associations.ResultsMean age was 35.48 ± 14.11 years (range 18–87 years).
