ABSTRACTThe aims of this study were to identify profiles of sedentary behaviour (SB) patterns, based on leisure-time self-reported SB modalities (screen, educative, social, and relaxing) and to evaluate changes in these profiles over 2 years among Spanish youth aged 8–18 years. Latent profile analysis (LPA), a data-driven analytic approach, was used to identify groups of boys and girls (n = 1553; 48% girls; mean±SD age: 12.56 ± 2.49 y) with distinct SB profiles using the SB modalities (time/d) as input variables. Latent transition analysis, an extension of LPA that uses longitudinal data, was used to analyse 2-year changes in these profiles. At baseline, four and three SB profiles were found among boys (labelled: screen, educative, social, and relaxing) and girls (labelled: screen/social, educative, and relaxing), respectively. Overall, more girls (range: 48%-67%) had the same profile over time, than boys (40%-52%). Participants with a screen or relaxing SB profile at baseline were more likely to have an educative profile after 2 years. Youth with a social and an educative SB profile at baseline were more likely to transition to profiles characterized by higher screen and social SB, respectively. Using a novel and person-centered approach, this study identified gender-specific SB profiles that were moderately stable over time. 相似文献

This study examined the effects of a syllable-based reading intervention for German second graders who demonstrated difficulties in the recognition of written words. The intervention focused on fostering word reading via syllable segmentation. The materials consisted of the 500 most frequent syllables typically read by 6- to 8-year-old children. The aims were to practice phonological recoding, consolidate orthographic representations of syllables, and routinize the access to these representations. Compared to children randomly assigned to a wait-list group, poor readers in the treatment condition showed significant improvements in standardized measures of phonological recoding, direct word recognition, and text-based reading comprehension after the 24-session intervention. Poor readers in the treatment condition also showed greater improvements in development of word recognition compared to children with efficient word recognition skills. The results provide evidence that a syllable-based reading intervention is a promising approach to increase struggling readers’ word recognition skills, which in turn will improve their reading comprehension. 相似文献

This research explored how seven primary school teaching assistants (TAs) experienced their role in supporting children's mental health. Interviews were analysed using Interpretative Phenomenological Analysis (IPA). The participants believed that they supported children's mental health and particularly referenced the close relationships that they formed with children. Throughout their accounts of supporting children, the TAs referenced helpful factors (e.g. support from other staff) and challenges (e.g. hierarchy) within the school system. Supporting children’s mental health was an emotional experience for the TAs; they discussed the rewarding element, however, the topic also elicited fear. The findings provide several implications for school staff and external professionals about how TAs can be supported in their role. These include involving TAs in training opportunities, providing TAs with supervision, considering communication systems in schools, and introducing a mental health policy. 相似文献

幼儿乳酸阈值及无氧阈心率的初步研究 总被引:4,自引:1,他引:3
对33名幼儿乳酸阈及其心率值进行测定,结果显示:3~5岁幼儿AT时血乳酸水平显著低于成人及青少年;幼儿亚极量强度运动后乳酸峰值大多出现在负荷后1min,反映了幼儿机体代谢的特异性.此实验结果可为幼儿有关生理机能和能量代谢的研究提供参数,所测得的乳酸阈心率值将为幼儿健身、减肥、增高等运动处方中运动强度控制提供科学依据. 相似文献
