Objective: To analyze the possible dose-response association between components of sports participation (intensity, volume and previous engagement) and 4-year mortality rates among Brazilian adults.

Methods: 679 males and females (mean age among men = 66.7 ± 9.3 years old and mean age among women = 64.8 ± 8.9 years old) composed the study sample. Sports participation was assessed using Baecke’s questionnaire, which considers intensity, duration and previous engagement. Medical records were used to identify the cause of the death. Cox regression analysis was performed to determine the independent associations of exercise components and mortality.

Results: Participants that reported exercising at moderate-vigorous intensity (Moderate/vigorous: 4.1% versus None/light: 10.3% [p-value = 0.012]; HR = 0.42 [0.1 to 0.94)] and for more than four months (≥4 months: 5.3% versus <4 months: 10.2% [p-value = 0.038]; HR = 0.47 [0.24 to 0.94]) had lower mortality risk. The percentage of survival according to all-cause mortality was significantly higher for participants engaged in sports at moderate-vigorous intensity (p-value = 0.014), as well as for those engaged in sports for periods superior than four months (p-value = 0.036).

Conclusion: We found higher percentage of survival among adults engaged in sports at moderate-vigorous intensity and with at least four months of previous engagement.  相似文献

There is conflicting evidence on the association between lower limb alignment characteristics and the incidence of running-related injury (RRI). Therefore, the primary aim of this study was to investigate the association between lower limb alignment characteristics and the incidence proportion of RRI in a convenience sample of recreational runners. A total of 89 recreational runners were included in this prospective cohort study. These participants had been running for at least six months and were injury-free at baseline. Lower limb alignment measurements were conducted in order to calculate lower limb discrepancy, Q-angle, subtalar angle and plantar index. All participants also answered a baseline and biweekly online surveys about their running routine, history of RRI and newly developed RRI over a period of 12 weeks. The prevalence of previous RRI and the 12-week incidence proportion of new RRI were calculated. Logistic regression analysis was performed to estimate the association between lower limb length discrepancy, Q-angle, subtalar angle and plantar ach index with the incidence proportion of RRI. The prevalence of previous RRI was 55.1% (n?=?49). The 12-week incidence proportion of new RRI was 27.0% (n?=?24). Muscle injuries and tendinopathies were the main types of RRI identified. The lower leg and the knee were the main anatomical regions affected. We did not find significant associations between lower limb length discrepancy, Q-angle, subtalar angle and plantar arch index and injury occurrence.  相似文献

Assessment of clinical skills is a critical element of undergraduate medical education. We compare a traditional approach to procedural skills assessment – the Objective Structured Clinical Examination (OSCE) with the Integrated Performance Procedural Instrument (IPPI). In both approaches, students work through ‘stations’ or ‘scenarios’ undertaking defined tasks. In the IPPI, all tasks are contextualised, requiring students to integrate technical, communication and other professional skills. The aim of this study was to explore students’ responses to these two assessments. Third‐year medical students participated in formative OSCE and IPPI sessions on consecutive days. Although performance data were collected in both assessments, quantitative data are not presented here. Group interviews with students were conducted by independent researchers. Data were analysed thematically. The OSCE and the IPPI were both valued, but for different reasons. Preference for the OSCE reflected the format of the summative assessment. The IPPI was valued for the opportunity to practise patient‐centred care in a simulated setting which integrated technical, communication and other professional skills. We posit that scenario‐based assessments such as the IPPI reflect real‐world issues of patient‐centred care. Although the limitations of this study prevent wide extrapolation, we encourage curriculum developers to consider the influence of assessments on what and how their students learn.  相似文献

Oral cancer has emerged as an alarming public health problem with increasing incidence and mortality rates all over the world. Therefore, the implementation of newer screening and early detection approaches are of utmost importance which could reduce the morbidity and mortality associated with this disease. Sensitive and specific biomarkers for oral cancer are likely to be most effective for screening, diagnosis, staging and follow-up for this dreaded malignancy. Unlike other deep cancers, oral cancer is located in oral cavity. Hence, the direct contact between saliva and oral cancer lesion makes the measurement of tumor markers in saliva an attractive alternative to serum and tissue testing. The DNA, RNA and protein molecules derived from the living cancer cells can be conveniently obtained from saliva. Thus, salivary biomarkers, a non-invasive alternative to serum and tissue-based biomarkers may be an effective modality for early diagnosis, prognostication and monitoring post therapy status. In the current post-genomic era, various technologies provide opportunities for high-throughput approaches to genomics and proteomics; which have been used to evaluate altered expressions of gene and protein targets in saliva of oral cancer patients. The emerging field of salivary biomarkers has great potentials to prove its clinical significance to combat oral cancer. Hence, we have reviewed importance of several salivary genomics and proteomics biomarkers for oral cancer.  相似文献

Home shared book reading during the preschool years is a strong predictor of students’ reading achievement in primary school, and, according to Sénéchal (2012), it can benefit more children from low socioeconomic status (SES) backgrounds. This study examines the association between frequency of book reading before the start of compulsory education and the reading achievement of 4th-grade students whose parents have high and low education levels in 22 European countries. Using data from the Progress in International Reading Literacy Study (PIRLS 2011), we show that the contribution of shared reading for the achievement of students from distinct SES backgrounds is different in different countries and that shared reading does not always benefit more children from low-SES backgrounds. Results are discussed in light of Sénéchal's home literacy model, the dynamics of cultural capital, and current policy efforts to support children's literacy development in European countries.  相似文献

The paper examines the emergence of the new definitions of women's position which constituted a ‘new orthodoxy’ at the turn of the nineteenth century in Portugal. ‘Women's nature’ and the ‘aims of women's education’ were the most debated issues. Different ideological positions were identified. The examination of these debates and of the emerging ‘new orthodoxy’ illustrates women's transition from ‘private’ forms of patriarchy to ‘public’ forms of patriarchy. It also demonstrates that this transition became an arena of contestation and negotiation, in the specific conditions of Portuguese society.  相似文献

Although basic math skill deficits are commonly encountered across elementary and secondary school students, few empirically validated, group‐administered interventions are available for educators attempting to prevent or remedy such problems. This study compared the effectiveness of two theoretically distinct interventions for improving the subtraction‐fact fluency of a general education class of second‐grade students. An alternating treatments design was used to compare a behavioral intervention, Cover, Copy, and Compare (CCC), to an intervention from a constructivist‐oriented resource, Facts That Last (FTL). Results demonstrated that CCC led to increases in math‐fact fluency, whereas the classwide response to FTL activities did not differ from the control condition. Two months postintervention, maintenance data revealed that the fluency increases associated with CCC were sustained. Discussion focuses on practical implications of the study as well as possible theoretical explanations for the documented results. © 2010 Wiley Periodicals, Inc.  相似文献

It seems that dehydration may impair decision-making performance in athletes. Purpose: This study aimed to investigate the influence of dehydration on passing decision-making performance in soccer players. Method: Participants were 40 male soccer players (Mage = 22.3 ± 2.3 years) who agreed to participate in the study and were randomly assigned to the following conditions: control (CON), dehydration (DEH), and euhydration (EUH). The players played in 2 games of 90 min in duration (2 45-min halves) followed by 2 15-min halves (overtime) with and without proper hydration. The Game Performance Assessment Instrument (GPAI) was considered for the analysis of passing decision making. Results: The GPAI analysis indicated effective reduction in the decision-making index in the DEH condition compared with the EUH and CON conditions, F(2, 38) = 31.4, < .05, ES = 0.8. Conclusions: In conclusion, dehydration may be considered a mediating factor in the passing decision-making performance of male soccer athletes.  相似文献
