A Canadian longitudinal study of the associations between weight control status and lifestyle behaviors during adolescence.

This study aimed to estimate associations between weight control status (trying to lose, gain or maintain weight) and lifestyle behaviors (moderate-to-vigorous physical activity (MVPA), screen time, and the consumption of breakfast, fast food, fruits and vegetables, and sugar-sweetened beverages (SSB)) in adolescents. Data from 919 adolescents in the MATCH study, in New Brunswick, Canada, who self-reported their weight control status at least once within 24 data collection cycles over 8 years (from 2011 to 2019) and from 812 who provided data at least once over the 7 cycles on eating behaviors were used. Generalized estimating equations were used.

Results from the Lebanese 2022 report card on physical activity for children and youth.

Objective: The Lebanese Active Healthy Kids Work Group (LAHKWG) synthesized literature published on physical activity (PA) indicators among ages 5- to 17- year-olds, using a recommended harmonized process by the Active Healthy Kids Global Alliance (AHKGA), to explore Lebanon's performance since its previous report card publication.

Methods: Peer reviewed literature, national surveys, and gray literature published since 2017, on 10 common AHKGA and two LAHKWG recommended indicators were examined. Common indicators included overall PA, organized sport and PA, active play, active transportation, community and environment, sedentary behaviors, physical fitness, family and peers, school, and government.

Economic Freedom, Climate Culpability, and Physical Activity Indicators Among Children and Adolescents: Report Card Grades From the Global Matrix 4.0.

Background: Macrolevel factors such as economic and climate factors can be associated with physical activity indicators. This study explored patterns and relationships between economic freedom, climate culpability, and Report Card grades on physical activity-related indicators among 57 countries/jurisdictions participating in the Global Matrix 4.0.

Physical activity motives have a direct effect on mental health.

Physical activity (PA) motives are associated with both moderate-to-vigorous intensity PA (MVPA) and mental health. Studies examining whether PA motives relate directly to mental health or indirectly through MVPA are lacking. This study examined the direct effect of five PA motives (i.

Associations between physical activity motives and trends in moderate-to-Vigorous physical activity among adolescents over five years.

This study examined the longitudinal associations between five physical activity (PA) motives and moderate-to-vigorous PA (MVPA) across a 5-year period spanning late childhood to middle adolescence.: Data ( = 937; 55% girls; mean age = 10.33 years) were drawn from the Monitoring Activities for Teenagers to Comprehend their Habits study.

Investigating physical activity knowledge and beliefs as correlates of behaviour in the general population: a cross-sectional study.

This study examines knowledge of physical activity (PA) guidelines for cancer prevention and beliefs of the role of PA in preventing cancer as correlates of moderate-to-vigorous intensity PA (MVPA) behaviour among adults. Measures assessing socio-demographic characteristics, knowledge of PA guidelines, and PA beliefs and behaviour were completed online by 654 adults (M = 36.92 ± 14.

A systematic review summarizing the effect of health care provider-delivered physical activity interventions on physical activity behaviour in cancer survivors.

Objective: To synthesize knowledge regarding the effect of health care provider-delivered physical activity interventions on cancer survivors' physical activity behaviour.

Methods: Ten electronic databases were searched for articles reporting on the effect of health care provider-delivered physical activity interventions on cancer survivors' physical activity behaviour. Articles were included if they met the following criteria: English-language, participants were adult cancer survivors, the effect of health care provider-delivered physical activity interventions on physical activity behaviour was assessed, and physical activity behaviour was measured at least twice.

Intensity and frequency of physical activity and high blood pressure in adolescents: A longitudinal study.

Despite limited evidence on the association between physical activity (PA) and blood pressure (BP) in youth, experts recommend that adolescents engage regularly in moderate-to-vigorous PA. We examined the relationships between PA intensity and frequency and the likelihood of having high BP in a population-based cohort of adolescents from Montréal, Canada. PA was self-reported every 3 months from grade 7 to 11, and BP was measured at ages 12.

Physical activity mediates the relationship between outdoor time and mental health.

Both spending time outdoors and participating in physical activity improve mental health. Given that the outdoor environment provides an ideal location for physical activity, better understanding of the relationships among time spent outdoors, physical activity and positive mental health is needed to help guide interventions. The aim was to examine if physical activity moderates or mediates the relationship between outdoor time and positive mental health.

Years Participating in Sports During Childhood Predicts Mental Health in Adolescence: A 5-Year Longitudinal Study.

Purpose: Sport participation promotes mental health and prevents mental illness. However, the association between specific sport profiles and mental health has not been examined. We investigate the longitudinal association between number of years with a recreational or performance sport profile and mental health during adolescence and whether these associations differ by sex.

First Physical Activity Report Card for Children and Youth in Lebanon.

: Evidence on physical activity (PA) indicators for children and youth at a national level is necessary to improve multilevel support for PA behaviors. Lebanon's first Physical Activity Report Card for children and youth (2018) aimed to fill this gap. : In line with the recommended methods of "Global Matrix 3.

Association of Teacher-Level Factors With Implementation of Classroom-Based Physical Activity Breaks.

Background: Classroom-based physical activity (CBPA) breaks are a common strategy to increase elementary school children's physical activity (PA) levels. There is limited research examining how teacher-level factors impact teacher implementation of CBPA breaks. In this study, we assessed the relationship of teacher-level factors with teacher use of a CBPA resource.

Global Matrix 3.0 Physical Activity Report Card Grades for Children and Youth: Results and Analysis From 49 Countries.

Background: Accumulating sufficient moderate to vigorous physical activity is recognized as a key determinant of physical, physiological, developmental, mental, cognitive, and social health among children and youth (aged 5-17 y). The Global Matrix 3.0 of Report Card grades on physical activity was developed to achieve a better understanding of the global variation in child and youth physical activity and associated supports.

The impact of life stresses on physical activity participation during adolescence: A 5-year longitudinal study.

Life stresses (LS) could affect levels of physical activity (PA) during adolescence, however research is limited. As different types of PA may have different determinants, the effects of LS on participation in moderate-to-vigorous PA (MVPA) and on organized and unorganized PA (OPA, UPA) were examined in a sample of 937 students (10-11 years-old) followed up over five years. Questionnaires were administered three times per year as part of the Monitoring Activities for Teenagers to Comprehend their Habits (MATCH) study.

Teacher-Level Factors, Classroom Physical Activity Opportunities, and Children's Physical Activity Levels.

Background: Classroom-based physical activity (CBPA) breaks are a cost-effective strategy to promote physical activity (PA) at school. Despite teachers' critical roles in sustained implementation of CBPA breaks, few studies examined the association of teacher-level factors with student PA levels, and none focused on rural schools.

Methods: We monitored children's PA levels over 4 consecutive school days at 6 rural Oregon elementary schools with Walk4Life pedometers.
