目的 探讨中老年女性在应用双能X线骨密度仪检测不同部位骨密度时应关注检测的部位。 方法 选取2012年9月至2014年4月在我院行双能骨密度检测的中老年女性,比较腰椎、髋部、前臂桡骨下1/3的骨密度(BMD)和T值。结果 中老年女性腰椎、髋部、前臂桡骨下1/3 3个部位的BMD和T评分比较,P<0.001有显著差异。随着年龄逐渐增大,腰椎、髋部和前臂BMD逐渐降低,但70岁以后腰椎BMD趋于平稳。腰椎T评分在40岁和50岁年龄段下降幅度较快,60岁以后下降有所减缓,70岁以后趋于平稳。髋部T评分在各年龄段呈匀速下降。前臂T评分随着年龄的增大下降幅度明显大于腰椎和髋部。骨质疏松检出率也随年增加而增加,重度骨质疏松检出率也以前臂为最高。结论 应用双能X线骨密度仪检测腰椎、髋部、前臂3个部位,经比较发现老年女性前臂骨密度和T评分明显低于腰椎和髋部,提示对老年女性骨质疏松诊断应同时检测前臂骨密度,以免出现骨质疏松的漏诊。  相似文献

目的 探讨青年人腰椎BMD和SD正常参考值影响骨质疏松症(OP)检出率的程度.方法 用GE-Lunar 公司的DXA仪测量骨密度,调查全国6个中心11418例腰椎PA和髋部BMD,建立了骨密度参考数据库.6个中心的仪器内部精度0.3%~0.7%,仪器间的精度1.1%.从T-score=(受试者BMD-青年人平均BMD)÷青年人骨密度SD值公式中可知,OP检出率与青年人平均BMD呈正比与SD值呈反比.结果 用6个中心及总体各自的青年人平均BMD和SD值为参考标准.对同一人群计算T-score和获得的OP检出率则不相同;发现青年人平均BMD每变化0.01g/cm2,则OP检出率变化1.6%(呈正相关),其SD值每变化0.01 g/cm2,则OP检出率变化4%(呈负相关).结论 青年人平均BMD和SD值不同引起OP检出率也不相同.为了让不同中心的OP检出率有可比性,建议同一个类型的BMD仪,同一个种族,同一个地区用一个设计较完善大样本的参考数据库,以其青年人正常参考值计算T-score.  相似文献

We examined the relative contribution of body composition to bone mineral density (BMD) at various sites in 1406 Korean rural men and women, aged 19–80 years, from July to August 2004. The BMD was measured at peripheral (distal forearm and calcaneus) and central (lumbar spine at L1–L4, femoral neck, trochanter, and Ward's triangle) using dual-energy X-ray absorptiometry. In multivariate analyses, the linear regression models were adjusted for relevant covariates. In premenopausal women, only lean mass had a significant positive correlation with BMD at all sites. In postmenopausal women, fat mass was significantly positively correlated with BMD at all sites, except the Ward's triangle; fat mass was the only determinant of BMD at the lumbar, distal forearm, and calcaneus sites, whereas both lean and fat mass contributed to BMD at the hip, with the effect of lean mass being slightly greater than that of fat mass. In younger men, lean mass had a significant positive contribution to BMD at all sites, whereas fat mass appeared to contribute negatively to BMD at all sites, except the calcaneus. In older men, lean mass made a significant positive contribution to the BMD at all sites; fat mass also made a significant positive contribution to the BMD at the forearm and calcaneus. These data indicate that in the Korean rural population, lean mass may be an important determinant of the BMD, whereas fat mass may contribute positively to BMD only in postmenopausal women and older men.  相似文献

Idiopathic osteoporosis in middle-aged men is characterized by low-level bone formation. Inhibited anabolism may be involved in the pathogenesis of the disease and amino acids may be of importance. In the present study fasting amino acid profiles in plasma and erythrocytes were determined in 22 male idiopathic osteoporosis (MIO) patients and in 20 age-matched healthy men and associated with bone mineral density, bone histomorphometry and hormones.The osteoporotic patients had normal plasma essential amino acids but increased non-essential amino acids (p = 0.001), particularly glutamine and glycine. The ratio essential/non-essential amino acids, an index of protein nutritional status, was decreased in the MIO patients (0.59 (0.04) μmol/l, mean (SD)), compared to controls (0.66 (0.05), p = 0.001).In the MIO patients, the ratio essential/non-essential plasma amino acids (r = 0.60, p = 0.003) was positively correlated with lumbar spine bone mineral density.The erythrocyte amino acids represent a large proportion of the free amino acids in blood. A novel finding was the lower levels of erythrocyte tryptophan in MIO (12 (2) μmol/l) compared to controls (16 (3), p = 0.001) and decreased erythrocyte/plasma ratio (0.28 (0.07) vs. 0.33, (0.06), p < 0.01), suggesting an altered amino acid transport of tryptophan between plasma and erythrocytes. In the combined group of MIO and control men (n = 42), bone mineral density was positively correlated with erythrocyte tryptophan in both the lumbar spine (r = 0.45, p = 0.003) and femoral neck (r = 0.56, p < 0.001). The bone histomorphometric variables wall thickness, trabecular thickness and mineral apposition rate were all positively associated with erythrocyte tryptophan levels in the MIO patients.In the combined group of MIO and controls, a multiple regression analysis showed that erythrocyte tryptophan could explain 22% of the variation of lumbar spine and 30% of the variation in femoral neck bone mineral density.We conclude that men with idiopathic osteoporosis have changes in free amino acid profiles which indicate their altered utilization. The correlations between tryptophan and bone mineral density and bone histomorphometry suggest a link between tryptophan and osteoblast function which may be important for bone health.  相似文献

Summary

The aim of this study was to determine the relationship between reduced muscle mass (sarcopenia) and areal bone mineral density (BMDa) in middle-aged and elderly community-dwelling European men. Men with sarcopenia had significantly lower BMDa and were more likely to have osteoporosis compared with men without sarcopenia.

Introduction

In men, the relationship between reduced muscle mass (sarcopenia) and BMDa is unclear. This study aimed to determine this relationship in middle-aged and elderly community-dwelling men.

Methods

Men aged 40–79 years from the Manchester (UK) and Leuven (Belgium) cohorts of the European Male Ageing Study were invited to attend for assessment including dual-energy X-ray absorptiometry, from which appendicular lean mass (aLM), fat mass (FM) and whole-body, spine and hip BMDa were determined. Relative appendicular skeletal muscle mass (RASM) was calculated as aLM/height². Muscle strength was assessed in subjects from Leuven. Sarcopenia was defined by RASM at <7.26 kg/m² and by the recent definition of the European Working Group on Sarcopenia in Older People (RASM at <7.26 kg/m2 plus low muscle function). Linear regression was used to determine the associations between aLM, FM, muscle strength and BMDa and logistic regression to determine the association between sarcopenia and osteoporosis.

Results

Six hundred seventy-nine men with a mean age of 59.6 (SD?=?10.7), contributed data to the analysis; 11.9 % were sarcopenic by the conventional definition. After adjustment for age and centre, aLM, RASM and FM were positively associated with BMDa. Men with RASM at <7.26 kg/m² had significantly lower BMDa compared with those with RASM at ≥7.26 kg/m2. In a multivariable model, aLM was most consistently associated with BMDa. Men with sarcopenia were more likely to have osteoporosis compared with those with normal RASM (odds ratio?=?3.0; 95 % CI?=?1.6–5.8).

Conclusions

Sarcopenia is associated with low BMDa and osteoporosis in middle-aged and elderly men. Further studies are necessary to assess whether maintaining muscle mass contributes to prevent osteoporosis.  相似文献

A retrospective study was carried out to determine the relationship between parity and bone mineral density (BMD) in middle-aged women. Eight hundred and twenty-five woman aged 41–76 years were recruited from four general practice registers in Cambridge. Subjects were unselected as to their health status. Each subject completed a detailed health questionnaire. Participation rate was 50%. The main outcome measure was BMD measured at the spine (L2–4,n=825) and hip (neck, intertrochanter and Ward's triangle;n=817) by dual-energy X-ray absorptiometry (DXA) using the Hologic QDR-1000 densitometer. It was found that the unadjusted mean BMD was significantly higher at all sites among the parous women (p=0.031 to <0.00001), and remained significantly higher at the femoral neck (p=0.025), intertrochanter (p=0.001) and Ward's triangle (p=0.045) after adjusting for age and body mass index (BMI). Similar findings were seen after stratifying for potential confounding variables. There was a consistent upward trend of BMD with increasing parity at all sites. Parity remained a significant independent predictor of BMD at all sites after controlling for age, BMI, menopausal status, oral contraceptive and hormone replacement therapy use, smoking status and breast-feeding status in multiple linear regression analyses. There was, on average, a 1.0% increase in BMD per live birth. Our findings therefore suggest a positive relationship between parity and bone mass.  相似文献

In order to evaluate the bone mineral density (BMD) of the entire skeleton and its major anatomical areas, total body DXA absorptiometry was performed in 330 postmenopausal women whose ages ranged from 42-85 years. Sixty-three of them were normal women and constituted the control group (Group 1). Two hundred sixty-seven were patients affected with postmenopausal osteoporosis: 107 osteoporotic patients had vertebral biconcavity deformities of grade 1 (Group 2), and the other 160 had vertebral wedge, biconcavity, and compression deformities of grade 2 (Group 3). Total body absorptiometry was assessed by a DXA system (Lunar DPX). Significant reduction in total body BMD values was observed in patients in Groups 2 and 3 (p less than 0.01): the bone loss was more intense in osteoporotic women of Group 3. The low values of the BMD in osteoporotic patients are, moreover, localized in the areas of spine, arms, and legs; the osteopenia was particularly enhanced in patients with grade 2 vertebral deformities. Multiple linear regression indicated that values of total BMD were significantly related to age and BMI. Receiver operating characteristic (ROC) analysis showed that total BMD provided high sensitivity: At 90% of specificity it was 78% for Group 2 and 89% for Group 3. DXA total body absorptiometry has demonstrated that, in postmenopausal osteoporotic women, the reduction in bone mass is not localized only in the spine, but also involves the appendicular skeleton.  相似文献
