Though there are exhaustive data about participation, performance trends, and sex differences in performance in different running disciplines and races, no study has analyzed these trends in stair climbing and tower running. The aim of the present study was therefore to investigate these trends in tower running. The data, consisting of 28,203 observations from 24,007 climbers between 2014 and 2019, were analyzed. The effects of sex and age, together with the tower characteristics (i.e., stairs and floors), were examined through a multivariable statistical model with random effects on intercept, at climber’s level, accounting for repeated measurements. Men were faster than women in each age group (p < 0.001 for ages ≤69 years, p = 0.003 for ages > 69 years), and the difference in performance stayed around 0.20 km/h, with a minimum of 0.17 at the oldest age. However, women were able to outperform men in specific situations: (i) in smaller buildings (<600 stairs), for ages between 30 and 59 years and >69 years; (ii) in higher buildings (>2200 stairs), for age groups <20 years and 60–69 years; and (iii) in buildings with 1600–2200 stairs, for ages >69 years. In summary, men were faster than women in this specific running discipline; however, women were able to outperform men in very specific situations (i.e., specific age groups and specific numbers of stairs).

Abstract The use of new technologies has brought many changes into consumer behaviour, especially into purchasing process. The aim of the article is to uncover the attitudes of different generations towards usage of new technologies in purchasing process and determine if the diffusion of innovative purchasing process is significantly different among different generations. The article presents the results of authors´ research of usage of new technologies in purchasing process, as well as attitudes towards it, among different age groups - Generation X, Y, Z and seniors. Results of hybrid research carried out by semi-structured interviews with 551 respondents show, that there are significant generational differences in all three components of attitude towards online purchase, which can be - due to its characteristics- considered the most complex use of new technologies in purchasing process. Results prove that the diffusion of innovation in the purchasing process is significantly influenced by the age group. With age the number of Innovators significantly drops and the percentage of Laggards rises. The ratio of those adopting “early” and “late” significantly changes according to age group as well. Majority of younger respondents are accepting the new technologies into purchasing process early (Innovators, Early Adopters, Early Majority). Middle-aged consumers accept the innovations proportionally - copying the Roger´s curve. Among seniors, the majority is “late” (Late Majority and Laggards).

Abstract Background Some pediatric endocrinologists recommend that girls with central precocious puberty (CPP) have cranial magnetic resonance imaging (MRI) performed only if they are younger than 6 years of age. However, no practice guidelines exist. The objective of this review was to assess the frequency of intracranial lesions in girls with CPP. Content We searched six electronic databases (PubMed, Cochrane, Web of Science, SCOPUS, ProQuest, and Dissertation & Theses) from 1990 through December 2015. We included studies on girls with CPP and MRI data. Case reports, case series, studies from the same author/group with the same patient population, and studies with conditions predisposing to CPP were excluded. Two physicians independently reviewed the search results and extracted data. A random-effects model was used to obtain pooled prevalence of positive MRI’s across studies. Heterogeneity among studies was evaluated with the Q-statistic. Publication bias was assessed with funnel plots and Egger’s test. Pooled prevalence was computed by age group. A linear regression assessed the relationship between intracranial lesion prevalence and healthcare availability. We included 15 studies with a total of 1853 girls <8 year old evaluated for CPP. Summary The pooled prevalence from all studies was 0.09 [95% confidence interval (CI) 0.06–0.12]. There was a significant heterogeneity, indicating the appropriateness of a random effects model in computing pooled prevalence. In the few studies stratified by age group, pooled prevalence was 25% in girls <6 years vs. 3% in girls 6–8 of age. Outlook Our results support that the benefit of routine MRIs in girls with CPP older than 6 years of age without any neurological concerns is not clear-cut.

Abstract Introduction. Several studies have shown that leisure contributes to improving seniors’ quality of life. However, some of this research has also highlighted the fact that there are marked physical, socioeconomic, and cultural disparities in this population. Material and methods. To this end, this article presents the results of a survey conducted in 2015 in Montreal with 464 respondents aged 50 and over regarding their interests and leisure practices. Results. This study highlights the importance that persons in this age group give to physical and outdoor recreation as well as free and outdoor activities. However, this study has also confirmed that there exist, regarding the problem of leisure, more or less significant differences among seniors and baby boomers which need to be taken into account by local actors. Conclusions. The results obtained and the correlated analyses clearly indicate that the senior population is not homogeneous with respect to their practices and their leisure needs. This analytical finding confirms that leisure and community services must be planned, programmed, and promoted taking into account these generational differences, as well as physical, socioeconomic, and cultural differences.

Background: In Israel, COVID19 vaccination coverage varies widely by population group and age. Despite the vaccine being locally and freely available in the entire country. Comparing crude coverage between localities and population groups is misleading because of differing age structures in different population groups. In order to describe inequalities in COVID19 vaccine initiation we determined differences in age-specific dose 1 vaccine coverage between the main population groups in Israel, and characterised the influence of age on vaccine coverage within each of these groups. Methods: We obtained daily doses administered by municipality and age from the Ministry of Health, and demographic data from the Central Bureau of Statistics. We determined whether the relative proportion of people vaccinated in each age group (15-19, 20-29, 30-39, 40-49, 50-59, 60+) changed by population group (General Jewish, Ultra-Orthodox and Arab) using ANOVA and quantified association between age, population group and vaccine coverage using binomial regression. Results: 8,507,723 individuals in 268 localities were included. Compared with the General Jewish population, vaccine coverage was lower among the Arab and Ultra-Orthodox populations and lowest in the Ultra-Orthodox population in all age groups. Gaps between population groups differed according to age group (p<0.001). In all populations, coverage decreased with decreasing age (p<0.001). The Ultra-orthodox population was the least vaccinated in all age groups relatively to those aged 60 and over. Conclusions: In all age groups, the Ultra-Orthodox population had the lowest vaccine coverage. The younger the age group, the more Ultra-Orthodox Jews are diverging from their age peers in terms of initiating COVID19 vaccination. These findings suggest generational differences in terms of vaccination behaviour in this group. Qualitative studies understanding the causes behind this divergence can inform tailored vaccination strategies.

While age group differences on social and political values have been frequently documented in survey data, it is often claimed that these differences are due to social composition factors rather than to age itself. In this analysis we test for the effects of age vs. social composition in explaining variation in four attitudinal dependent variables. Using a sample especially drawn to study generational differences, and employing a multivariate statistical model, it was found that age differences were only modestly reduced by social composition variables. It is concluded that nonartifactual age group differences do exist on the dependent variables.

Twelve trainable mentally retarded children were given six weeks of instruction in the use of adjectives, polars, and locative prepositions. Specially prepared Language Master cards constituted the program. Posttests indicated that children in the older chronological age group earned significantly higher scores than those in the younger group. Children in the younger group made significant increases in scores, particularly in learning prepositions. A multisensory approach and active involvement in learning appeared to be major factors in achievement gains.
