    Background: We investigated the association of bone mineral density (BMD) by detected dual-energy X-ray absorptiometric (DXA) method and hemoglobin (Hb) levels in a large sample. Methods: The current study enrolled 371 postmenopausal women (82 anemic patients), who were screened for osteopenia or osteoporosis by DXA. Patients with osteopenia or osteoporosis (T score < -1.0 SD) were grouped as having low bone mass (LBM). Results: Anemic patients were older and had significantly higher duration of menopause. When compared with subjects with normal Hb, anemic patients had significant lower femur t score, femur BMD, femur Z score, spinal t score, spinal BMD and spinal Z score (p<0.001). Additionally, the ratio of subjects with LBM in the femur and spine were significantly high in anemic patients (p

    The effect of breast-feeding duration on bone mineral density in postmenopausal Turkish women: a population-based study
    (Termedia Publishing House Ltd, 2011) Yazıcı, Selma; Korkmaz, Uğur; Erkan, Melih; Korkmaz, Nurdan; Baki, Ali Erdem; Alçelik, Aytekin; Ataoğlu, Safinaz
    Introduction: In the present study, we investigated the effects of breast-feeding time on bone mineral density (BMD) later in life. Material and methods: The current study was based on a retrospective analysis of 586 postmenopausal women with a mean age of 60.8 years, who were screened for osteoporosis by dual energy X-ray absorptiometry (DXA). They were classified into 4 groups with respect to the duration of their breast-feeding as never (group 1), 1-24 months (group 2), 25-60 months (group 3), or > 60 months (group 4). Bone mineral density results for the femur neck and lumbar spine were classified into 3 groups according to WHO criteria as normal (T score > -1.0 SD), osteopenia (T score -1.0 to -2.5 SD), and osteoporosis (T score < -2.5 SD). Patients with osteopenia or osteoporosis (T score < -1.0 SD) were considered as having low bone mass (LBM). Results: We found a correlation between duration of lactation and femur BMD or spine BMD in the study population (r = 0.116, p < 0.005; r = -0.151, p = 0.001, respectively). Significant differences were found between femur BMD and spine BMD of groups in one-way ANOVA analysis (p = 0.025, p = 0.005, respectively). Additionally, when compared with the other three groups, group 4 was older and had longer duration of menopause (p < 0.01). In logistic regression analysis, age and body mass index were found as independent risk factors of LBM [odds ratio: 1.084 (95% CI 1.031-1.141); odds ratio: 0.896 (95% CI 0.859-0.935)], while duration of lactation was not found as an independent predictor of LBM. Conclusions: In this study, we have found that changes of bone metabolism during lactation had no effect on postmenopausal BMD measured by DXA. Consequently, it can be suggested that long breast-feeding duration is not a risk factor for low bone mass later in life.
