Walking and biologic ageing: Evidence based on NHANES telomere data     

Larry A. Tucker 《Journal of sports sciences》2020,38(9):1026-1035

ABSTRACT

The length of telomeres is an objective measure of biologic ageing. This study evaluated the extent minutes of walking per week are associated with leukocyte telomere length (LTL) in a random sample of 5,823 U.S. adults. The investigation was cross-sectional and data were obtained from the National Health and Nutrition Examination Survey (NHANES). LTL was measured by the quantitative polymerase chain reaction method. Walking minutes was calculated from walking frequency and duration measures. Results showed that for each year of chronological age, telomeres were 15.6 base pairs shorter (P < 0.0001). With walking minutes and LTL treated as continuous variables, the relationship was quadratic, not linear (F = 11.2, P = 0.0023). With walking time divided into three categories, adults who performed ≥ 150 minutes of walking per week had longer telomeres than those who did no regular walking, and those who did some, but less than the recommendation (F = 5.0, P = 0.0137). Regular walkers were estimated to have a biologic ageing advantage associated with 6.5–7.6 years less biologic ageing compared to non-walkers, after adjusting for covariates. Additional investigations designed to study causality and the mechanisms associated with the walking and LTL relationship are needed.  相似文献   

Is academic tracking related to gains in learning competence? Using propensity score matching and differential item change functioning analysis for better understanding of tracking implications     

《Learning and Instruction》2020

This study analyzes gains in cognitive components of learning competence with respect to cohorts based on ability tracking in a Czech longitudinal study. Propensity score matching is used to form parallelized samples of academic and non-academic track students and to eliminate the effect of selective school intake. We applied regression models on the total scores to test for the overall track effect. Furthermore, we analyze scores and gains on the subscores and check for differential item functioning in Grade 6 and in change to Grade 9. While after 3 years, no significant difference between the two tracks was apparent in the total learning competence score, we did, however, find significant differences in some subscores and in the functioning of some items. We argue that item-level analysis is important for deeper understanding of the tracking implications and may provide the basis for more precise evidence-based decisions regarding the tracking policy.  相似文献   

体医融合项目的风险治理:一种新的面向与选择——从非典到新型冠状肺炎谈起     

李明  许文鑫 《武汉体育学院学报》2020,54(5):25-30

体医融合和非医疗健康干预可以有效促进疾病管理与健康服务模式的形成,但体医融合项目治理初期仍然受到理念融合、体医融资、部门协同等因素的影响。该文以病毒、人体免疫与体育运动的体医融合关系视角,依据共生理论对体医融合项目的风险治理逻辑进行了阐述。采用文献资料法、数理统计法等对体医融合项目风险治理的相关个案进行了整理,并基于NVIVO11.0质性分析软件对体医融合个案进行识别分析,构建了体医融合项目风险治理的影响因素评价指标体系,包括13个一级指标30个二级指标。最后提出了体医融合项目风险治理的路径选择(1)将体医融合理念提升至构建公共卫生保障体系战略的高度;(2)落地变现体医融合项目购买方案;(3)打造政府精准购买体医融合项目区块链。  相似文献
