了解机关工作人员骨质健康状况,探寻变化规律及其影响因素。应用定量超声(QUS)技术,对厦门市852名机关工作人员进行跟骨密度测量和分析,其中男性498人,女性354人,年龄23—60岁,各以每5岁为一年龄组。结果:青年男性(21—30岁)骨硬度指数(SI)明显高于同龄组的女性(P<0.05),男性SI的峰值出现早于女性;SI随年龄增加呈逐渐下降趋势,男性51—55岁、56—60岁分别降到同性别骨峰值的84.9%和83.3%;女性51—55岁降为同性别骨峰值的91.8%;男女SI均与年龄呈负相关,与身高、体重呈正相关,而与BMI无相关性;男女骨质正常者所占比例随年龄增长而逐渐降低,骨质疏松患病率随年龄增长而逐渐增高。结论:厦门市机关工作人员骨密度总体表现满意,男性高于女性;身高、体重、年龄是影响骨密度的重要因素;合理的体育锻炼可以增加骨密度,预防骨质疏松症。 相似文献

台湾研究人员指出,持续几年的喝茶习惯有助于维持人体骨质密度。台湾国立成功大学医院的吴志新和张志珍两位教授研究得出,茶对全身尤其是腰椎和臀部的骨质密度起到保护作用。他们认为,随着时间的积累,茶,尤其是绿茶里高含量的氟化物,以及类黄酮和植物性雌激素都有助于维持骨质密度。茶里的其他成分可能会抑制骨质再吸收,促进骨的新陈代谢。他们得出结论:喝茶习惯的持续时间而不是喝茶的数量决定了增加骨质密度的作用有多大。这种效果在经常喝茶并坚持10年时间以上的人身上最显著。喝茶有助增加骨质密度@王增 相似文献

近来,有很多读者询问老年人在患了骨质疏松以后应该如何锻炼?怎么样锻炼更安全?这里笔者就这几位读者提的这个问题谈谈自己的看法,再介绍一组简单、安全、有效的预防和改善骨质疏松状况的锻炼方法,供读者朋友们参考:体育锻炼可以促进新陈代谢和全身的血液循环,增强骨组织对所需营养、特别是对钙质的吸收,从而有效提高骨质的硬度和韧性。骨质疏松的患者除了在医生的指导下进行药物治疗进行补钙以外,坚持进行科学合理的体育锻炼是非常重要的。骨质疏松的患者在进行体育锻炼时一定要注意循序渐进,持之以恒,盲目进行剧烈运动有可能会造成身体伤… 相似文献

AbstractU.S. women are ageing. This is causing rises in osteoporosis prevalence and risk of fracture with related increases in health care costs. Replacing sedentary time with light physical activity may represent a cost effective public health solution to osteoporosis in elderly women. The National Health and Nutrition Examination Survey conducted over the period 2003–2006 provided cross-sectional data on bone mineral density and objectively assessed physical activity among 1,052 women aged 50–85 years old. Substitution analysis was applied to estimate increased bone mineral density and reduced osteoporosis for those women replacing 30?min of sedentary time with an equivalent amount of light physical activity. Substitution of 30?min of sedentary time with an equal amount of light physical activity was associated with increased bone mineral density of about 3?mg/cm2 and a 12% reduced risk of osteoporosis in the spine. When considering overweight women and women over 65 years of age, this association was reinforced and it extended to the pelvis, legs and trunk, resulting in a consistent bone mineral density increase of about 3–6?mg/cm2. The substitution of 30?min of sedentary time with an equal amount of light physical activity appears a possible primary prevention method to reduce osteoporosis and related increases in risk of fracture, mortality, and health care costs in women over 50 years old. 相似文献

There is evidence from previous cross-sectional studies that high volumes of certain sports, including running, swimming and cycling, may have a negative impact on bone mineral density. The aim of the present study was to evaluate prospectively the effects of high athletic training in individuals who engage in high volumes of all three of these activities (triathletes). Bone mineral density for the total body, arms and legs was determined by dual-energy X-ray absorptiometry in 21 competitive triathletes (9 men, 12 women) at the beginning of the training season and 24 weeks later. Age, body mass index, calcium intake and training volume were also recorded to examine potential mediators of bone mineral density change. Men had greater bone mineral density at all sites than women. No significant changes were observed over the 24 weeks for either total body or leg bone mineral density. Bone mineral density in both arms increased by approximately 2% in men ( P ? 0.03), but no change was observed for women. Change in bone mineral density at all sites was unrelated to age, body mass index, calcium intake and training volume. The results suggest that adverse changes in bone mineral density do not occur over the course of 6 months of training in competitive triathletes. 相似文献

不同健身形式对女性体成分和骨代谢的影响 总被引:7,自引:0,他引:7
探讨不同健身形式对女性体成分和骨代谢的影响。150名女性受试者随机分为1个对照组,9个健身组。9个健身组进行6个月的健身运动,测试运动后的体重、去脂体重、肌力、心功能、血AKP、ACP、E2。结果:1)有氧运动与肌肉力量锻炼相结合可使去脂体重和去脂体重/体重指数明显提高,有氧运动能提高心功能,提示,体成分可作为健身效果评价的重要指标之一。2)经6个月的锻炼,9个运动组的E2浓度明显升高,有氧运动结合肌肉力量训练的AKP活性升高,ACP活性下降,表明,有氧运动对E2的浓度、有氧运动结合肌肉力量对AKP、ACP水平的影响较大。建议健身者在进行有氧运动锻炼时,应加强肌肉力量的训练,以提高去脂体重和骨代谢水平,防治骨质疏松症。 相似文献
