Basic Psychological Need Satisfaction as Correlates of Physical Activity Trajectories During Adolescence.

This analysis aimed to (1) identify longitudinal joint trajectories of participation in organized and unorganized physical activity contexts, and level of daily moderate-to-vigorous physical activity (MVPA) and (2) assess whether basic psychological need satisfaction during adolescence differentiates between membership in different physical activity trajectories. Participants (n = 888; 56% girls) reported their involvement in 36 different physical activities, level of MVPA, and their perceived satisfaction of competence, autonomy, and relatedness satisfaction in physical activity up to three times per year, over 8 years (from ages 10 to 17 years). Group-based multi-trajectory models were used to identify longitudinal joint trajectories of physical activity participation.

Identification of distinct physical activity profiles through adolescence: a longitudinal qualitative description study.

Introduction: We aimed to better understand longitudinal physical activity experiences among initially active adolescents and to identify and describe distinct physical activity profiles.

Methods: A sample of 23 physically active participants [52% female; mean age = 12.2 (0.

Association between physical fitness and executive functions in cognitively healthy female older adults: a cross-sectional study.

Cardiovascular endurance and muscular fitness seem to impact specific cognitive components in older females. However, it remains uncertain whether these relate to executive functions or if these correlations are limited to specific physical fitness indicators. This study aimed to determine the association between specific physical fitness components and executive functions in community-dwelling older females.

Migration of etonogestrel subcutaneous contraceptive implants: systematic review and recommendations for practice.

Introduction: Migration is a rare but serious complication of the etonogestrel contraceptive implant, and little is known about its extent.

Purpose: To document and characterise cases of etonogestrel contraceptive implant migration in the scientific literature.

Methods: A systematic review of Medline, Embase and Global Health databases was carried out between January 2000 and January 2023 to identify articles presenting implant migrations.

Association between changes in habitual stepping activity and cognition in older adults.

Advancing age is associated with declines in cognitive function. Although physical activity is thought to protect against this decline, it is unclear how a short-term uptake in daily steps or a decline in day-to-day step variability may contribute to cognition among older adults. We tested associations between changes in step counts, day-to-day step variability and executive cognitive functions among older adults taking part in a physical activity intervention.

Does Participating in a Variety of Activities at a Variety of Locations or With Different People Predict Physical Activity Behavior Among Adolescents? The Mediating Role of Perceived Variety.

We examine whether adolescents' participating in a variety of physical activities, locations, and/or with a variety of people relates to physical activity 16 months later and whether perceptions of variety mediate these relationships. Adolescents (N = 369) completed measures indicating various physical activities they participated in, where they primarily participated, and with whom they primarily participated, at three time points over a year (averaged for baseline measures). Perceptions of variety was measured 8 months later.

Correlates of Active School Transportation During the COVID-19 Pandemic Among Canadian 7- to 12-Year-Olds: A National Study.

Background: Active school transportation (AST) is an important source of physical activity for children and a potentially important climate change mitigation strategy. However, few studies have examined factors associated with AST in the context of the COVID-19 pandemic.

Methods: We used baseline data from a longitudinal survey to investigate correlates of AST during the second wave of COVID-19 (December 2020).

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.

Children's Independent Mobility, School Travel, and the Surrounding Neighborhood.

Introduction: Children's active travel to and from school (AST) and children's independent mobility (CIM) are consistently positively associated with physical activity (PA); however, few researchers have investigated associations between objective measures of the environment and indicators of AST and CIM in national samples.

Methods: A national sample of 2,067 Canadian parents of 7- to 12-year-old children was recruited in December 2020. Regression analyses were used in 2023 to assess the association between geographic information system measures of park density, blue space, population density, greenspace, intersection density, and CIM and AST to and from school.

Frailty is associated with worse executive function and higher cerebral blood velocity in cognitively healthy older adults: a cross-sectional study.

Frailty is characterized by an increased vulnerability to adverse health events. Executive function impairment is an early sign of progression towards cognitive impairments. Whether frailty is associated with executive function and the associated mechanisms are unclear.

Long-Term Consequences of COVID-19 in Predominantly Immunonaive Patients: A Canadian Prospective Population-Based Study.

: Lingering symptoms are frequently reported after acute SARS-CoV-2 infection, a condition known as post-COVID-19 condition (PCC). The duration and severity of PCC in immunologically naïve persons remain unclear. Furthermore, the long-term consequences of these chronic symptoms on work and mental health are poorly documented.

Puberty timing and relative age as predictors of physical activity discontinuation during adolescence.

Among same-age adolescents, those who enter puberty relatively later and those who are relatively younger (e.g., born later in the year) might be at greater risk of physical activity discontinuation.

Longitudinal Associations Between Body-Related Self-Conscious Emotions and Weight Control Status During Adolescence.

Purpose: Half of adolescents are trying to change their weight and body-related self-conscious emotions may influence these intentions. We estimated associations between body-related shame, guilt, embarrassment, envy, authentic pride, and hubristic pride and weight control status (trying to maintain, lose, or gain weight) throughout adolescence in girls and boys.

Methods: Six annual cycles of self-administered questionnaires were collected from age 12-17 in the Monitoring Activities of Teenagers to Comprehend their Habits (MATCH) study (n = 776).

Convergent validity and inter-rater reliability of a lower-limb multimodal physical function assessment in community-dwelling older adults.

Lower-limb physical function declines with age and contributes to a greater difficulty in performing activities of daily living. Existing assessments of lower-limb function assess one dimension of movement in isolation or are not time-efficient, which discourages their use in community and clinical settings. We aimed to address these limitations by assessing the inter-rater reliability and convergent validity of a new multimodal functional lower-limb assessment (FLA).

Association between physical activity education and prescription during prenatal care and maternal and fetal health outcomes: a quasi-experimental study.

Background: Physical activity (PA) during pregnancy is associated with healthy gestational weight gain (GWG) and a reduced risk of developing gestational diabetes (GD), gestational hypertension (GHT) and fetal macrosomia. However, in Canada, less than 20% of pregnant women meet PA recommendations. This study assessed associations between an intervention including PA education by prenatal nurses and a PA prescription delivered by physicians and fetal and maternal outcomes.

Canadian children's independent mobility during the COVID-19 pandemic: A national survey.

Independent mobility (IM) is associated with children's physical activity and indicators of social, motor, and cognitive development. We surveyed Canadian parents of 7- to 12-year-olds (n = 2291) about social-ecological correlates of IM in the second wave of COVID-19 (December 2020). We used multi-variable linear regression models to identify correlates of children's IM.

Urbanization, air pollution, and water pollution: Identification of potential environmental risk factors associated with amyotrophic lateral sclerosis using systematic reviews.

Introduction: Despite decades of research, causes of ALS remain unclear. To evaluate recent hypotheses of plausible environmental factors, the aim of this study was to synthesize and appraise literature on the potential associations between the surrounding environment, including urbanization, air pollution and water pollution, and ALS.

Methods: We conducted a series (n = 3) of systematic reviews in PubMed and Scopus to identify epidemiological studies assessing relationships between urbanization, air pollution and water pollution with the development of ALS.

The Change in Exergaming From Before to During the COVID-19 Pandemic Among Young Adults: Longitudinal Study.

Background: Exergaming may be an important option to support an active lifestyle, especially during pandemics.

Objective: Our objectives were (1) to explore whether change in exergaming status (stopped, started or sustained exergaming, or never exergamed) from before to during the COVID-19 pandemic was related to changes in walking, moderate-to-vigorous physical activity (MVPA) or meeting MVPA guidelines and (2) to describe changes among past-year exergamers in minutes per week exergaming from before to during the pandemic.

Methods: A total of 681 participants (mean age 33.

Body image self-conscious emotions get worse throughout adolescence and relate to physical activity behavior in girls and boys.

Body image is a commonly-reported factor perpetuating declines in physical activity levels during adolescence. However, the evidence is predominantly qualitative, cross-sectional, and focused on girls. Furthermore, the affective dimension of body image has been overlooked compared to the perceptual (e.

Symptoms of depression and anxiety increased marginally from before to during the COVID-19 pandemic among young adults in Canada.

We documented changes in depressive and anxiety symptoms from before to during the COVID-19 pandemic among young adults and investigated whether changes differed across participant characteristics. Data were available in an investigation of 1294 grade 7 students recruited in 1999-2000. For this analysis, we used data collected pre-pandemically in 2017-20 (mean (SD) age = 30.

Training the Next Generation of Diabetes Researchers: Evaluation of the Diabetes Action Canada Training and Mentoring Program.

Background: The Diabetes Action Canada Training and Mentoring (DAC-TM) Program launched in June 2017, with the goal of building capacity in the next generation of diabetes researchers in Canada in patient-oriented research (POR).

Methods: We conducted a program evaluation of the DAC-TM program using a sequential, mixed-methods research design.

Results: Our analysis of 82 surveys and 22 in-depth interviews from a wide range of DAC-TM Program stakeholders revealed consistent patterns in experience with the program.

Description of sport participation profiles and transitions across profiles during adolescence.

Few studies describe sport participation profiles in the general population using multiple characteristics. Therefore, the objective of this study was to identify sport participation profiles during adolescence and to describe transitions across profiles from grades 5 to 12 (age 10 to 18 years). We used data from 916 participants (55% girls; age 10-12 years at inception) of the Monitoring Activities of Teenagers to Comprehend their Habits (MATCH) study.

Does Relative Age Influence Organized Sport and Unorganized Physical Activity Participation in a Cohort of Adolescents?

Despite their prevalence, the longitudinal impacts of relative age effects (RAEs) on sport and other forms of physical activity (PA) are understudied. This study examined longitudinal participation patterns in organized sport (team and individual), unorganized PA, and non-participation with respect to RAEs in a prospective cohort of adolescents. Data from the first 24 cycles of the MATCH study were used for analyses.

Trajectories of beverage consumption during adolescence.

Beverages contribute substantially to daily energy and nutrient intakes. However, little is known about the co-development of beverage consumption throughout adolescence. This study aimed to investigate the presence of naturally occurring sub-groups of girls and boys following distinct trajectories of various types of beverage consumption (i.
