This study aimed to investigate the relationship between the consumption of various nutrients and bone mineral density (BMD) in middle-aged women. This cross-sectional survey was conducted based on the clinical records of 157 women aged 38–76. Their lumbar spine BMD was measured with dual-energy X-ray absorptiometry and dietary habits were assessed with the brief-type self-administered diet history questionnaire. Participants were divided into premenopausal (n = 46) and postmenopausal (n = 111) groups and the correlation between the BMD Z-score (Z-score) and the intakes of 43 nutrients was investigated separately for each group. In premenopausal women, the daily intake of ash, calcium, and α-tocopherol was positively correlated with the Z-score (Pearson’s correlation coefficient, R = 0.31, 0.34, 0.33, p = 0.037, 0.020, 0.027, respectively). When dividing the consumption of ash, calcium, and α-tocopherol into low, middle, and high tertiles, the Z-score significantly differed only between the α-tocopherol tertiles. After adjustment for age, body mass index, and lifestyle factors, daily intake of α-tocopherol remained significantly associated with the Z-score (regression coefficient = 0.452, p = 0.022). No nutrient was found to be significantly correlated with the Z-score in postmenopausal women. Increase in the intake of α-tocopherol could help maintain bone mass in premenopausal women.

Abstract Context Pituitary hormonal deficiencies in patients with craniopharyngioma may impair their bone health. Objective To investigate bone health in patients with craniopharyngioma. Design Retrospective cross-sectional study. Setting Dutch and Swedish referral centers. Patients Patients with craniopharyngioma (n = 177) with available data on bone health after a median follow-up of 16 years (range, 1-62) were included (106 [60%] Dutch, 93 [53%] male, 84 [48%] childhood-onset disease). Main outcome measures Fractures, dual X-ray absorptiometry-derived bone mineral density (BMD), and final height were evaluated. Low BMD was defined as T- or Z-score ≤-1 and very low BMD as ≤-2.5 or ≤-2.0, respectively. Results Fractures occurred in 31 patients (18%) and were more frequent in men than in women (26% vs. 8%, P = .002). Mean BMD was normal (Z-score total body 0.1 [range, -4.1 to 3.5]) but T- or Z-score ≤-1 occurred in 47 (50%) patients and T-score ≤-2.5 or Z-score ≤-2.0 in 22 (24%) patients. Men received less often treatment for low BMD than women (7% vs. 18%, P = .02). Female sex (OR 0.3, P = .004) and surgery (odds ratio [OR], 0.2; P = .01) were both independent protective factors for fractures, whereas antiepileptic medication was a risk factor (OR, 3.6; P = .03), whereas T-score ≤-2.5 or Z-score ≤-2.0 was not (OR, 2.1; P = .21). Mean final height was normal and did not differ between men and women, or adulthood and childhood-onset patients. Conclusions Men with craniopharyngioma are at higher risk than women for fractures. In patients with craniopharyngioma, a very low BMD (T-score ≤-2.5 or Z-score ≤-2.0) seems not to be a good predictor for fracture risk.

This research aimed to investigate the relationship between abdominal obesity and lower bone mineral density (BMD) at non-weight-bearing site in Korean men using data from the Korea National Health and Nutrition Examination Survey, which is a nationwide cross-sectional survey. The study population ( n = 5,941) was selected from the 2009–2010 survey. Abdominal obesity in men was defined as waist circumference ⩾ 90 cm. Lower BMD state was defined as having T-score of −2.5 or below. To investigate the association, multiple logistic regression analysis was performed. Abdominal obesity was highly associated with lower non-weight-bearing site (lumbar spine [LS]) BMD after adjustment (odds ratio [OR] 1.61, 95% CI [1.06, 2.44], p = .026). Also, abdominal obesity was a risk factor for lower LS BMD, especially in age groups of those in their 20s and those over 60s (OR 5.53, 95% CI [1.27, 24.07], p = .023 for 20s; OR 2.19, 95% CI [1.19, 4.02], p = .011 for 60 years or older). Abdominal obesity in Korean men is associated with lower BMD at non-weight-bearing site (LS), especially in younger and older age groups. Further research might be recommended to prove the mechanism or causality.

Progressive Bone Deficit in Epilepsy. Sheth RD, Binkley N, Hermann BP. Neurology 2008;70(3):170–176. OBJECTIVE: Chronic treatment with antiepileptic medication is associated with reduced bone mineral density (BMD), which may underlie the two-to sixfold increase in fracture rates observed in patients with epilepsy. The objective was to determine the timing of the BMD deficit in ambulatory children with epilepsy. METHODS: A cross-sectional evaluation was conducted in 82 ambulatory children aged 6 to 18 years (12.4 ± 3.3 years) with epilepsy for <1 year (n = 18), 1 to 5 years (n = 37), and 6 or more years (n = 27). Controls were 32 healthy children aged 12.8 ± 2.6 years. Age- and sex-corrected total body BMD Z-score was measured. RESULTS: Total BMD Z-score was lower in children with epilepsy (0.10 ± 0.96; CI = −0.08, 0.34) compared to controls (0.57 ± 0.74; CI = 0.3, 0.84; p = 0.03). Increasing duration of epilepsy was associated with a progressive reduction in BMD compared to controls (Spearman r = −0.197; p = 0.03). Compared to controls, those with epilepsy for 1 to 5 years had a mean BMD Z-score of 0.13 ± 0.78 (CI = −0.13, 0.39; p = 0.04) and in those treated for 6 or more years BMD was 0.06 ± 1.11 (CI = −0.38, 0.5; p = 0.04). For those with epilepsy for <1 year BMD was 0.23 ±1.1 (CI = −0.31, 0.77; p = 0.21). CONCLUSIONS: Children treated for epilepsy sustain significant bone mineral density (BMD) deficit compared to controls during the initial 1 to 5 years of treatment which progressively worsens thereafter. This progressive BMD deficit may be a contributing factor to the increased fracture risk observed in patients with epilepsy and may accelerate aging-related osteoporosis.

Background: Osteoarthritis of any joint may exert different effects on bone mineral density that may be the result of several mechanisms including change in the pattern of weight load distribution. In this cross-sectional study we tried to find correlations between unilateral knee osteoarthritis and bone mineral density of hips and lumbar vertebrae. Methods: Forty three patients with knee osteoarthritis (unilateral or more severe in one side) were recruited in this study. The American college of Rheumatology Criteria was followed for the diagnosis of osteoarthritis. Dual X-Ray absorptiometry was used to obtain the T score and the Z score of the hips and lumbar vertebrae. Results: The T score and Z score of the hip and T score of the femoral neck, at the side with ipsilateral knee osteoarthritis was lower than the other side (p < 0.05). The mean Z score and T score of the vertebrae was negative irrespective of the side of osteoarthritis. Conclusions: Bone mineral density of the hip with ipsilateral knee osteoarthritis was lower than the other side, which suggests that BMD may be sensitive to some extent in detecting osteoporosis in these patients; it has also been observed that osteoarthritis might not affect bone mineral density of the hips and lumbar vertebrae in the same manner or to the same extent.
