Further, body image concerns are implicated globally as a hindrance to sports engagement among adolescents but are rarely acknowledged in India. Due to a lack of research, the unique restrictions to sport participation faced by girls in India are yet to be understood.

Physical activity levels tend to decline steeply among children aged between 8 and 12 years, even though children's behavioral patterns are largely governed by familial structures. Similarly, parents' activity levels have been generally reported as lower than those of nonparents of comparable age.

Long-term physical health conditions (LTPHCs) are associated with poorer psychological well-being, quality of life, and longevity. Additionally, individuals with LTPHCs report uncertainty in terms of condition aetiology, course, treatment, and ability to engage in life. An individual's dispositional ability to tolerate uncertainty-or difficulty to endure the unknown-is termed intolerance of uncertainty (IU), and may play a pivotal role in their adjustment to a LTPHC.

Objectives: This systematic review assessed the influence of the COVID-19 pandemic and associated restrictions on body image, disordered eating (DE), and eating disorder outcomes.

Methods: After registration on PROSPERO, a search was conducted for papers published between December 1, 2019 and August 1, 2021, using the databases PsycINFO, PsycARTICLES, CINAHL Plus, AMED, MEDLINE, ERIC, EMBASE, Wiley, and ProQuest (dissertations and theses).

Results: Data from 75 qualitative, quantitative, and mixed-methods studies were synthesized using a convergent integrated approach and presented narratively within four themes: (1) disruptions due to the COVID-19 pandemic; (2) variability in the improvement or exacerbation of symptoms; (3) factors associated with body image and DE outcomes; (4) unique challenges for marginalized and underrepresented groups.

The present study aimed to examine effects of motivational and social cognition constructs on children's leisure-time physical activity participation alongside constructs representing implicit processes using an extended trans-contextual model. The study adopted a correlational prospective design. Secondary-school students (N = 502) completed self-report measures of perceived autonomy support from physical education (PE) teachers, autonomous motivation in PE and leisure-time contexts, and social cognition constructs (attitudes, subjective norms, perceived behavioral control), intentions, trait self-control, habits, and past behavior in a leisure-time physical activity context.

Background: Inadequate physical activity in young people is associated with several physical and mental health concerns. Physical education (PE) is a potentially viable existing network for promoting physical activity in this population. However, little research has been conducted on whether PE teachers can influence students' engagement in leisure-time physical activity.
