Sixty-nine female patients, mean age 27.5 years (range 20-40), with a past or current history of anorexia nervosa (DSM Ill-R) had spinal trabecular bone density assessed by single energy quantitative CT scan. Current exercise and dietary calcium levels were assessed by detailed questionnaires and categorized. A semi-structured interview was used to record weight, menstruation, exercise and dietary calcium intake histories from early adolescence. Serum sex hormones and total calcium assays were measured. Bone density was significantly lower in the patients compared to 31 controls. Bone density was significantly positively correlated with body mass index, and negatively correlated with illness duration and duration of amenorrhoea. Exercise levels, dietary calcium intake and taking an oestrogen pill did not correlate significantly with bone density. Recovered patients did not have osteopaenia but they had shorter illness histories than non-recovered patients. Management to minimise bone loss should focus on weight gain and resumption of normal menstruation.

Introduction: Osteoporosis is a multifactorial polygenetic disease of which the genetic determinants are modulated by hormonal, environmental and nutritional factors. Identifi cation of the risk factors for osteoporosisrelated to nutrition is important in the prevention and treatment of this disease, considering that these factors can be modifi ed. The aim of this study was to examine infl uence of dietary calcium intake on bonemineral density in postmenopausal women who hadn’t a deficit of estrogen in their menstrual history.Methods: A total of 100 postmenopausal women living in Sarajevo area, aged 50-65 years, without estrogen deficiency in menstrual history were included in the study. Mineral bone density was measured at the lumbarspine and proximal femur by Dual–Energy X–ray Absorptiometry using Hologic QDR-4000 scanner. Examination and control group were formed based on mineral bone density values. The women in the examinationgroup had osteoporosis. The women in the control group had osteopenia or normal mineral bone density. Estimates of daily dietary calcium intake were performed based on a Food Frequency Questionnaire.Results: The average daily intake of dietary calcium among women who had osteoporosis was 967.32 mg, and in women who hadn’t osteoporosis 1195.12 mg. The difference between two groups was statistically significant (p<0.001). There was registered signifi cant correlation between intake of dietary calcium and mineral bone density in examination (p<0.01) and in control group (p<0.01).Conclusion: The results of this study have shown that adequate daily intake of dietary calcium in postmenopausal women aged 50-65 years living in Sarajevo area, which hadn’t estrogen defi ciency in their menstrualhistory (in the group of women without osteoporosis amounted to 1195.12 mg) has a positive impact on bone mineral density.

Higher Dietary Acidity is Associated with Lower Bone Mineral Density in Postmenopausal Iranian Women, Independent of Dietary Calcium Intake

Findings of studies on the link between dietary acid-base balance and bone mass are relatively mixed. We examined the association between dietary acid-base balance and bone mineral density (BMD) in a sample of Iranian women, hypothesizing that a higher dietary acidity would be inversely associated with BMD, even when dietary calcium intake is adequate. In this cross-sectional study, lumbar spine and femoral neck BMDs of 151 postmenopausal women aged 50 - 85 years were measured using dual-energy x-ray absorptiometry. Dietary intakes were assessed using a validated food frequency questionnaire. Renal net acid excretion (RNAE), an estimate of acid-base balance, was then calculated indirectly from the diet using the formulae of Remer (based on dietary intakes of protein, phosphorus, potassium, and magnesium; RNAERemer) and Frassetto (based on dietary intakes of protein and potassium; RNAEFrassetto), and was energy adjusted by the residual method. After adjusting for potential confounders, multivariable adjusted means of the lumbar spine BMD of women in the highest tertiles of RNAERemer and RNAEFrassetto were significantly lower than those in the lowest tertiles (for RNAERemer: mean difference -0.084 g/cm2; P=0.007 and for RNAEFrassetto: mean difference - 0.088 g/cm2; P=0.004). Similar results were observed in a subgroup analysis of subjects with dietary calcium intake of >800 mg/day. In conclusion, a higher RNAE (i. e. more dietary acidity), which is associated with greater intake of acid-generating foods and lower intake of alkali-generating foods, may be involved in deteriorating the bone health of postmenopausal Iranian women, even in the context of adequate dietary calcium intake.
