Cognitive frailty is the simultaneous clinical manifestation of both physical frailty and cognitive impairment. This paper aimed to propose and test an operational definition of cognitive frailty. The following specific aims were pursued: (i) to rate the prevalence of cognitive frailty; (ii) to evaluate differences in cognitive functioning among robust, pre-frail, and frail individuals; (iii) to examine the association of cognitive frailty with disability, in a sample of Italian community-dwelling older adults. Five hundred and ninety-four older adults (mean age 73.6 years, SD=5.8) were involved in this cross-sectional study. Cognitive frailty was operationalized using the Mini Mental State Examination (cut-off score equal or less than 25) for the evaluation of cognitive functions and the five criteria of the Cardiovascular Health Study (cut-off score equal or higher than 3) for the evaluation of physical frailty. Participants positive for both instruments were classified as cognitively frail. The outcome was disability measured with the Groningen Activity Restriction Scale. Descriptive statistics, one-way and two-way analysis of covariance (ANCOVA) were carried out. The prevalence rate of cognitive frailty was 4.4%. The one-way ANCOVA, controlling for age and gender, showed a significant difference (p< .001) among robust, pre-frail, and frail participants for the cognitive functioning. Moreover, cognitively frail individuals showed a difference (p<.001) in disability in comparison with non-frail participants. Our results are significant and provide empirical evidence about the usefulness of the cognitive frailty concept.
The relative age effect (RAE) is a common phenomenon observed in youth sports and is characterized by a significant over-representation of athletes born close to the date of selection. However, there is a lack of research on RAE in world-class track and field athletes and it is not clear if this effect persists into adulthood. Thus, this study examined for the first time the prevalence and magnitude of RAE at world class level in all track and field disciplines. Birthdates of 39,590 athletes (51.6% females) ranked in the International Association of Athletics Federations top 100 official lists between 2007 and 2018 season of Under 18, Under 20, and Senior categories were collected. Under 18 and Under 20 athletes born in the first week of the year are about 2 to 3.5 times more likely to be included in the top-100 ranking than the athletes born in the last week of the year. RAE was overall larger in male compared to female athletes. In some disciplines (e.g., throwing events) RAE persists in Senior category. These findings suggest that in some disciplines relatively younger athletes may have less chances of reaching world-class performances even in the adulthood. Governing bodies should reflect upon their policies for athlete support and selection to minimize the RAE.
The Daily Mile™ is an innovative school-based intervention that requires children to run or jog outside for 15 min at a self-selected pace during class time. Today, only one study has investigated the efficacy of The Daily Mile on physical fitness, which was conducted with Scottish children. Thus, we aimed to evaluate the feasibility and effectiveness of The Daily Mile in Italian primary schools. A total of 486 children participated in The Daily Mile for 3 months (experimental group), whereas 309 children continued their daily school routine (control group). The 6-min run test, standing long jump, body mass index, and waist-to-height ratio were assessed. Their teachers completed surveys for assessing the intervention acceptability. After correction for age and gender, significant group × time interactions were observed in the 6-min run test and standing long jump results. In the post-test period, the experimental group showed improvement in the 6-min run test and standing long jump results. Overall, the teachers were satisfied with the program and found it suitable for their school context and easy to implement. The Daily Mile was successfully implemented and smoothly accepted in the day routine of Italian primary schools.
This study aims to assess the reliability, construct validity (convergent/divergent), and criterion validity of the Italian version of the Tilburg Frailty Indicator (TFI). The TFI is a self-report questionnaire for screening frailty in older adults. Two hundred and sixty-seven community-dwelling older adults were involved. Psychometric properties were analyzed using validated instruments. Adverse outcomes such as disability, falls, and visits to a general practitioner were detected. Participants were mainly women (59.9%), with a mean age of 73.4 years (SD = 6.0). Internal consistency reliability was acceptable. Construct validity was good, since each item of the TFI correlated as expected with corresponding frailty measures. Convergent and divergent validity were adequate for all the domains of the TFI. Criterion validity was excellent for disability and mediocre for the other two outcomes. This study supports the validity of the Italian TFI and offers to clinicians and scientists a multidimensional instrument for identifying frail individuals in the Italian context.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
