Development of sport policy and practice recommendations for pregnant, postpartum and parenting Canadian high-performance athletes.

Our objective is to describe the development of evidence-based policy and practice recommendations for pregnant, postpartum and parenting Canadian high-performance athletes. A community-based participatory research approach was employed as the study design, and data were generated via a rapid review of existing sport policy for pregnant and postpartum athletes, followed by an extensive consultation and engagement process with key sport stakeholders via survey and one-on-one and group interviews. 102 sport stakeholders participated via the survey (n=56), individual and group interviews (n=33), and follow-up interviews (n=13).

"Is It Realistic?": A Qualitative Study of the Experiences of Elite Women Athletes Considering Parenthood.

Background And Objective: As the visibility and acceptance of athlete-mothers increase, so does the number of women athletes considering parenthood. Yet, many athletes struggle with the decision to become a parent while competing at the elite level due to the significant changes and uncertainties that have been reported by pregnant and parenting athletes. The experiences of women athletes considering parenthood are under-represented in the vast sport literature but are necessary for developing evidenced-based policies and practices that can support women's equitable participation in high-performance sport contexts.

A grounded theory of personal development in high-performance sport environments.

Objectives: The purpose of this study was to develop a grounded theory of how to promote personal development in high-performance sport environments.

Methodology: Individual interviews were conducted with 32 members of the Canadian junior and senior national biathlon teams, including 18 athletes (9 women, 9 men, M = 20.8 years, SD = 2.

Filling the evidence void: exploration of coach and healthcare provider experiences working with pregnant and postpartum elite athletes - a qualitative study.

Objective: Recent research grounded in the experiences of elite female athletes has shed light on the complex challenges of navigating sport environments that do not support or value pregnant or postpartum athletes. The purpose of this study was to explore the unique experiences of coaches and healthcare providers working with pregnant and postpartum elite athletes, and to identify actionable steps for research, policy and culture change to support them.

Methods: Sixteen participants (five coaches, three physicians and eight physiotherapists), who have worked with pregnant and/or postpartum elite athletes within the last 5 years, participated in this qualitative study.

Visual representations of single- and multi-sport participation in a youth swimming sample: Implications for definitions and discussions of early specialization.

Academic literature and sport policy documents have cited concerns about an increasing prevalence of early sport specialization, with associated burnout, dropout, and injury. However, evidence to support such statements is limited. Definitions of early specialization vary, but a common criterion is continued participation in a single sport, prior to adolescence.

The effect of neighborhood walkability on changes in physical activity and sedentary behavior during a 12-week pedometer-facilitated intervention.

Background: Pedometer-facilitated interventions encourage physical activity via the accumulation of steps. Mixed evidence suggests that neighborhood walkability might influence the effectiveness of physical activity interventions, including pedometer-facilitated interventions. Our study investigated the moderating effect of neighborhood walkability on immediate (4-week) and short-term (12-week) changes in self-reported neighborhood-specific leisure and transportation walking, leisure-based moderate and vigorous-intensity physical activity, and leisure-based screen time during a pedometer-facilitated intervention (UWALK).

We're not Superhuman, We're Human: A Qualitative Description of Elite Athletes' Experiences of Return to Sport After Childbirth.

Background: A growing number of athletes return to elite sport following childbirth. Yet, they face significant barriers to do so safely and successfully. The experiences of elite athletes returning to sport following delivery are necessary to support evidence-informed policy.

"We're categorized in these sizes-that's all we are": uncovering the social organization of young women's weight work through media and fashion.

Background: For decades, dominant weight discourses have led to physical, mental, and social health consequences for young women in larger bodies. While ample literature has documented why these discourses are problematic, knowledge is lacking regarding how they are socially organized within institutions, like fashion and media, that young women encounter across their lifespan. Such knowledge is critical for those in public health trying to shift societal thinking about body weight.

Pushing for change: a qualitative study of the experiences of elite athletes during pregnancy.

Objectives: Athletes train and compete at the elite level during their reproductive years, yet sport policies that support pregnant athletes are lacking. The experiences of elite athletes during pregnancy are vastly under-represented, and such voices are needed to support evidence-informed policy. Thus, the purpose of this qualitative study was to describe the experiences of elite female athletes as they navigate pregnancy, and to identify sport policy considerations regarding participation during pregnancy.

The ruling of weight: An institutional ethnography investigating young people's body weight surveillance work.

Rationale: Dominant framing of childhood obesity as a public health burden has increased weight stigma towards young people in larger bodies. However, weight stigma literature is generally limited by its focus on individuals' attitudes and beliefs, overlooking the broader social conditions shaping stigma. Further, few weight stigma studies have been conducted from young people's standpoint; little is known about how they navigate stigmatizing environments while growing up.

The Use of a Nonrefundable Tax Credit to Increase Children's Participation in Physical Activity in Alberta, Canada.

Background: Potential income disparities were examined in the (1) awareness and uptake of the Children's Fitness Tax Credit (CFTC), and (2) physical activity (PA) of children from families who did and did not claim the credit in Alberta, Canada in 2012 and 2014.

Methods: Secondary analyses of 3 cross-sectional data sets of grade 5 students (10-11 y) were performed, including Alberta Project Promoting healthy Living for Everyone Schools 2012 (N = 1037), and Raising healthy Eating and Active Living Kids Alberta 2012 (N = 2676), and 2014 (N = 3125). Parents reported whether they claimed the CFTC in the previous year, their education and household income, and their child's gender and PA.

Health Outcomes after Pregnancy in Elite Athletes: A Systematic Review and Meta-analysis.

Purpose: This study aimed to evaluate postpartum maternal health and training outcomes of females who were competing or training as elite athletes before or during pregnancy.

Methods: Online databases were searched up to August 26, 2020. Studies of any design and language were eligible if they contained information on the relevant population (postpartum athletes [any period after pregnancy]), exposure (engaged in the highest level of sport immediately before or during pregnancy), comparators (sedentary/active controls), and outcomes: maternal (breastfeeding initiation and duration, postpartum weight retention or loss, bone mineral density, low back or pelvic girdle pain, incontinence [prevalence or severity of stress, urge or mixed urinary incontinence, fecal incontinence], injury, anemia, diastasis recti, breast pain, depression, anxiety) and training (<6 wk time to resume activity, training volume or intensity, performance level).

Realtors' Perceptions of Social and Physical Neighborhood Characteristics Associated with Active Living: A Canadian Perspective.

Realtors match home-seekers with neighborhoods that have built and social characteristics they desire to pursue active lifestyles. Studies have yet to explore realtors' perspectives on neighborhood design that supports active living. Using qualitative description, our study was to explore the perceptions and understandings of neighborhood design (walkability, healthy, bike-ability, vibrancy, and livability) among urban residential realtors.

Associations between objectively-measured and self-reported neighbourhood walkability on adherence and steps during an internet-delivered pedometer intervention.

Background: Accumulating evidence suggests that the built environment is associated with physical activity. The extent to which the built environment may support adherence to physical activity interventions is unclear. The aim of this study was to investigate whether the neighbourhood built environment constrains or facilitates adherence and steps taken during a 12-week internet-delivered pedometer-based physical activity intervention (UWALK).

The Indigenous Youth Mentorship Program (IYMP) is a peer-led health promotion program developed for elementary school students in Indigenous school communities in Canada. A local young adult health leader (YAHL) and high school mentors offer students healthy snacks, physical activity games, relationship building activities and cultural teachings. IYMP aims to improve children's health and wellbeing and empower Indigenous youth and communities.

Elite Athletes and Pregnancy Outcomes: A Systematic Review and Meta-analysis.

Purpose: The purpose of this systematic review was to evaluate fetal and maternal pregnancy outcomes of elite athletes who had participated in competitive sport immediately before conception.

Methods: Online databases were searched up to March 24, 2020. Studies of any design and language were eligible if they contained information on the relevant population (pregnant women), exposure (engaged in elite sport immediately before pregnancy), and outcomes (birth weight, low birth weight, macrosomia, preterm birth, fetal heart rate and pulse index, cesarean sections, instrumental deliveries, episiotomies, duration of labor, perineal tears, pregnancy-induced low back pain, pelvic girdle pain, urinary incontinence, miscarriages, prenatal weight gain, inadequate/excess prenatal weight gain, maternal depression or anxiety).

Development of a consensus statement on the role of the family in the physical activity, sedentary, and sleep behaviours of children and youth.

Background: Children and youth who meet the physical activity, sedentary, and sleep behaviour recommendations in the Canadian 24-Hour Movement Guidelines are more likely to have desirable physical and psychosocial health outcomes. Yet, few children and youth actually meet the recommendations. The family is a key source of influence that can affect lifestyle behaviours.

Markers of Early Specialization and Their Relationships With Burnout and Dropout in Swimming.

Empirical evidence directly associating early sport specialization with burnout and dropout is lacking, although a relationship is theorized. Research in this area relies on time-intensive retrospective interviews or questionnaires that generate large amounts of data. The optimal use of these data for assessing early specialization (ES) and its relationship with key criterion variables is unclear.

Adolescents' involvement in decision-making for pediatric weight management: A multi-centre, qualitative study on perspectives of adolescents and health care providers.

Objective: To explore adolescents' and health care providers' (HCPs) perspectives on adolescents' involvement in decision-making within multidisciplinary clinical care for pediatric weight management.

Methods: In this multi-centre, qualitative description study, we purposefully recruited 13-17-year-olds with overweight or obesity and HCPs from two pediatric weight management clinics in Edmonton and Ottawa, Canada. Participants completed one-on-one, in-person, semi-structured interviews (adolescents) or focus groups (HCPs), which were audio-recorded, transcribed verbatim, and managed using NVivo 11.

Barriers and enablers for adopting lifestyle behavior changes in adolescents with obesity: A multi-centre, qualitative study.

Background: Many adolescents with obesity do not meet recommendations for nutrition, physical and sedentary activities, and sleep habits, all of which can influence weight management.

Objective: To explore barriers and enablers that influenced the adoption of lifestyle behavior changes among adolescents receiving multidisciplinary clinical care for pediatric weight management.

Methods: In this multi-centre, qualitative description study, we used purposeful sampling to recruit 13-17 year olds (body mass index ≥85th percentile) enrolled in one of two pediatric weight management clinics in Edmonton and Ottawa, Canada.
