Does modality matter? A latent profile and transition analysis of sedentary behaviours among school-aged youth: The UP&DOWN study

ABSTRACT

The 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.     

The effect of number of siblings and birth order on educational attainment: Empirical Evidence from Chinese General Social Survey

Data from China demonstrate that the effect of the number of siblings on education is restricted by many factors, such as children’s gender, urban or rural household registration, whether there is only one child, the birth order of children within the family, and parents’ status. Chinese families have significant preferences for the eldest son and the youngest son. Moreover, research based on the natural experiment and instrumental variable approach suggests that market-oriented reform of education has increased the cost of family education expenditures since China’s reform and opening up, which further aggravates the negative impact on education of having many siblings in an urban setting.

Invisible children? The need for support groups for siblings of disabled children

Previous research and first-hand experience suggest that a child with a disability can have a profound effect on family life. Although the need for sibling support has been acknowledged in legislation, the implications for non-disabled siblings remain unclear. In this article, Angie Naylor, lecturer in psychology, and Phil Prescott, senior lecturer in childhood and youth studies, both based at Edge Hill, review a number of key themes emerging from the literature on sibling support. They go on to report the findings from an in-depth study of one sibling support group. The work was carried out in partnership with Barnardo's in the north-west of England and involved setting up a sibling support group, in response to an analysis of local need, and evaluating its impact. This research indicates a clear need for further service provision to meet the needs of the siblings of disabled children who attended the scheme. Angie Naylor and Phil Prescott argue for a reinvigorated debate about the needs of such children and champion the importance of listening to children and valuing what they have to say. The results of this small-scale evaluation project have clear implications for future research and, potentially, for policy and practice.
