Prevalence of SARS-CoV-2 infection among obstetric patients in Ottawa, Canada: a descriptive study.

Background: There is limited information on the prevalence of SARS-CoV-2 infection in obstetric settings in Canada, beyond the first wave of the COVID-19 pandemic (February to June 2020). We sought to describe the prevalence of SARS-CoV-2 infection in pregnant people admitted to triage units at a tertiary care hospital in Ottawa, Canada.

Methods: We conducted a descriptive study of pregnant people admitted to obstetric triage assessment units at The Ottawa Hospital between Oct.

Correction: Maternal gestational weight gain and objectively measured physical activity among offspring.

The effect of a physical activity intervention on preschoolers' fundamental motor skills - A cluster RCT.

Objectives: To assess the effect of a physical activity intervention delivered in the childcare centres (CC), with or without a parent-driven home physical activity component, on children's fundamental motor skills (FMS).

Design: Six-month 3-arm cluster randomized controlled trial.

Methods: Preschoolers were recruited from 18 licensed CC.

Effects of a Preschool Intervention on Physical Activity and Body Composition.

Objective: To investigate the effect of a preschool physical activity intervention program delivered in licensed childcare settings, with or without a parent-facilitated home component, on children's daily physical activity, sedentary time, and body composition.

Study Design: For this cluster randomized controlled trial, 18 childcare centers were randomly allocated in equal numbers to the typical curriculum comparison group, childcare intervention alone (CC), or childcare intervention with parental involvement. Accelerometers were used to asses physical activity and sedentary time, and body composition was measured by bioelectrical impedance.

Maternal gestational weight gain and objectively measured physical activity among offspring.

Objective: Animal studies have suggested that maternal weight-related factors during pregnancy can program offspring physical activity in a sex-dependent manner. However, there is limited evidence in humans. The purpose of this study was to investigate the association between maternal gestational weight gain (GWG) and offspring total physical activity (TPA) level and to determine whether these associations are moderated by sex of offspring or maternal pre-pregnancy weight status.

Effects of Child Care Intervention on Physical Activity and Body Composition.

Introduction: This study evaluated whether intervening with child care providers would increase physical activity (PA) and reduce adiposity in preschoolers.

Methods: This was a two-arm, parallel group, cluster RCT whereby six child care centers were randomly assigned in equal numbers to intervention (n=40 children) or control (n=43 children). Participants were aged 3-5 years and attended licensed child care centers.

Does Intervening in Childcare Settings Impact Fundamental Movement Skill Development?

Purpose: Knowing that motor skills will not develop to their full potential without opportunities to practice in environments that are stimulating and supportive, we evaluated the effect of a physical activity (PA)-based intervention targeting childcare providers on fundamental movement skills (FMS) in preschoolers attending childcare centers.

Methods: In this two-arm cluster-randomized controlled trial, six licensed childcare centers in Ottawa, Canada, were randomly allocated into one of two groups (three controls, n = 43; three interventions, n = 40). Participants were between the ages of 3 and 5 yr.

Activity Begins in Childhood (ABC) - inspiring healthy active behaviour in preschoolers: study protocol for a cluster randomized controlled trial.

Background: Today's children are more overweight than previous generations and physical inactivity is a contributing factor. Modelling and promoting positive behaviour in the early years is imperative for the development of lifelong health habits. The social and physical environments where children spend their time have a powerful influence on behaviour.

Evaluating a fruit and vegetable program: in eastern Ontario schools.

Purpose: Effectiveness was evaluated for a fruit and vegetable program developed to encourage Canadian elementary school children to eat the recommended number of daily servings. Also examined was whether the program modified children's personal factors, perceived social environment, and perceived physical environment.

Methods: A prospective, quasi-experimental trial was conducted to compare the eight schools receiving the intervention curriculum (Freggie Friday schools [FFS]) with six control schools (CS).

Impact of accelerometer epoch length on physical activity and sedentary behaviour outcomes for preschool-aged children.

Background: The Canadian Health Measures Survey uses accelerometry to collect physical activity and sedentary behaviour data. Between cycles 2 and 3, a transition was made from 60-second to 15-second epochs in accelerometry data for children aged 3 to 5. This study examines the impact of epoch length on physical activity and sedentary behaviour outcomes.

Physical activity promotion in the preschool years: a critical period to intervene.

The primary aim of this paper is to provide a rationale for the necessity of intervening with a physical activity intervention in the preschool years and why the daycare environment is amenable to such intervention. We also review the prevalence of physical activity, sedentary behaviour and obesity in the preschool population and the impact that these lifestyle behaviours and conditions have on the health of preschool aged children, as secondary objectives. Moreover we discuss implications for intervention and research using a "lessons learned" model based on our research team's experience of conducting a randomized controlled trial aimed at increasing physical activity, reducing sedentary behaviour and improving motor skill development and body composition in preschoolers.
