目的：为肯尼斯·库珀（Kenneth H. Cooper）于1970年提出的库珀中心纵向研究（CCLS）提供详细历史。方法：对库珀中心纵向研究人群和库珀诊所所检查的重要参数，以及库珀诊所患者的各种疾病发病率和死亡率进行数据描述。并对近50年来已发表的库珀中心纵向研究的主要研究结果进行总结。结果：在库珀诊所检查期间，通过最大跑台运动测试客观地测量出的心肺功能（CRF）已成为各种疾病发病率和死亡率的强大且独立的风险因素。更具体地说，库珀中心纵向研究明确表明，中高水平的心肺功能与人体全因、心血管疾病和癌症死亡率有显著相关关系。此外，已经证明，中年人群的心肺水平是全因痴呆、Ⅱ型糖尿病、慢性肾病、癌症发病率和存活率以及一些其他慢性疾病的预测因子。因此，库珀中心纵向研究结果还表明，中年人群的心肺水平与老年时期的医疗保健成本呈显著相关。结论：除罕见情况以外，已经进行了近50年的库珀中心纵向研究的研究结果表明，相对于较低水平的心肺功能，中高水平的心肺功能可以有效预防许多疾病。 相似文献

While empirical evidence suggests that elite athletes have superior lifespan outcomes relative to the general population, less is known regarding their causes of death. The purpose of this study was to critically examine the mortality outcomes of deceased National Basketball Association and American Basketball Association players. Death data were collected from publicly available sources until 11 December 2015, and causes of death were categorized using the International Classification of Diseases, Tenth Revision (ICD). Mortality was measured through: i) cause-specific crude death rates (CDR), ii) estimates of death rates per athlete-year (AY), and iii) binary and multinomial regression analyses. We identified 514 causes of death from 787 deceased players (M = 68.1 y ± 16.0) from 16 different ICD groups, 432 of which were from natural causes. Findings showed similar leading causes of death and CDRs to sex- and race-matched controls, higher death rate differences per AY within time-dependent variables (i.e., birth decade, race, and height), and a higher likelihood of dying below the median age of death for black and taller players, although this was highly confounded by birth decade. More complete knowledge of mortality outcomes would provide broad public health applications and disarm harmful stereotypes of elite athlete health. 相似文献

Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60?years old. The literature search produced 271 records for physical performance (n?=?119), frailty (n?=?31), and mortality (n?=?121). Finally, only 13 articles fulfilled the inclusion criteria and were included in this review. All articles but one included in the physical performance section (n?=?9) showed a negative association between longer time spent in SB and physical performance. A significant association of SB with higher odds of frailty was found, however this association disappeared after adjusting for cognitive status. Lastly, two of the three included studies showed positive associations between SB and mortality, but this effect decreased or even disappeared in the more adjusted models. In conclusion, there is consistency that SB is negatively associated with physical performance. However, the relationship between objectively measured SB and frailty incidence and mortality rates remains unclear and deserves further research. The use of homogenous criteria to assess SB and the inclusion of more robust research designs will help clarifying the independent effects that SB could have on physical performance, frailty, and mortality. This will ultimately help designing more efficient and comprehensive physical activity guidelines for older adults. 相似文献

Although interdisciplinary efforts in teaching and research are promoted as a possible antidote to increasing disciplinary separatism in colleges and universities, evaluations of interdisciplinary efforts in the classroom, particularly those spanning the traditional science-humanities divide, are not frequently documented. This article describes the development, execution, and assessment of a unique effort in interdisciplinary teaching in which four doctoral candidates from widely varying home disciplines collaborated to create and teach a “truly interdisciplinary” course for first-year students centered on the pervasiveness of humankind's quest for immortality. Assessment of the course indicates several desirable student outcomes, including the development of a more mature world view and appreciation for different epistemologies, which recommend the continuation of this and similar interdisciplinary efforts. While students at times found the enormous number of disciplines potentially related to the central topic overwhelming, at the conclusion of the course, they largely identified the exposure to new perspectives as an exciting and worthwhile academic experience. Similar interdisciplinary efforts in the classroom are encouraged, though ample course development time is recommended to maximize success. 相似文献

Women's schooling has long been regarded as one of the best investments in development. Yet countries vary widely in the extent to which a year of schooling conveys useful skills and knowledge and hence schooling and education cannot be treated as synonyms. Using two different cross-nationally comparable data sets which contain measures of schooling, assessments of literacy, and life outcomes for more than 50 countries we show the association of women's education, defined as schooling and the acquisition of literacy, with four life outcomes (fertility, child mortality, empowerment, and financial practices) is much larger than the standard estimates of the gains from schooling alone. In our preferred instrumental variables (IV) estimates, that correct for the attenuation bias induced by measurement error, the gain from education is more than 3 times larger than the standard OLS estimates of gains from schooling alone. While our results are not causal estimates, if anything like our results are true in the causal pathways whereby schooling and learning lead to improvements in women's well-being this implies the estimates of the costs and benefits of expansions in grade attainment versus improving learning need to be adjusted accordingly. 相似文献

随着我国社会保障体系改革的深入,各种养老金计划的发展速度越来越快,规模也越来越大,而由死亡率非预测性的降低导致的长寿风险（longevity risk）对养老金计划的经营带来的威胁也越来越重,对长寿风险的研究具有重要的理论及现实意义。利用Lee-Carter模型对死亡率进行建模,预测其在未来的发展趋势。为有效控制长寿风险,可以利用保单条款控制风险、利用产品组合“对冲”风险、利用再保险分散风险、风险证券化以及开发金融衍生工具对冲风险。 相似文献

Why with an increase in the amount of health information, and ways of accessing it, so many people experience poor health? What is the role of health library and information professionals in improving public health? These questions are of great interest to me. There are many examples of initiatives, particularly in the public library sector, which address health issues, however they are often very local and best practice is not always shared. Clearly changing the health status of a population requires more than information, but information is clearly an essential component. If health information is to be effective in improving public health then we need to address health literacy, and this is where health library and information professionals can play a significant role. Through this journal and the other activities of the Health Libraries Group I hope we can share good practice and explore new ways that health library and information workers can improve the health of individuals and communities. 相似文献

This pilot study from self-selected institutions of higher education provides an estimate of the causes and rates of mortality among college students between the ages of 18 and 24 years old. One hundred fifty-seven 4-year colleges participated in an online survey of student deaths during one academic year. A total of 254 deaths were reported. The mortality rates (per 100,000) were as follows: total accidental injuries, 10.80; suicide, 6.17; cancer, 1.94; and homicide, 0.53. Within the accident and injury category, alcohol-related vehicular deaths (per 100,000) were 3.37 and alcohol-related nontraffic injuries were 1.49. Men had significantly higher rates of suicide (10.46) than women (2.34). Suggestions for future research and implications of these findings are discussed. 相似文献
