Longitudinal Associations Between Movement Behaviours and Development Among Infants Using Compositional Data Analysis.

Background: The study examined the longitudinal associations of sleep time, restrained time, back time and tummy time with development in a sample of infants using compositional data analysis.

Methods: Participants were a subsample of 93 parent-infant dyads from the Early Movers project in Edmonton, Canada. Parents completed a 3-day time-use diary at 2, 4 and 6 months of age.

MINISTOP 3.0: Implementation of a mHealth obesity prevention program within Swedish child healthcare - study protocol for a cluster randomized controlled trial.

Background: Previously, we have reported on the efficacy and real-world effectiveness of a parent-oriented mobile health intervention (MINISTOP 1.0 and 2.0), which have shown improvements in pre-school children's lifestyle behaviours.

Physical activity and circulating inflammatory markers and cytokines during pregnancy: A population-based cohort study.

Introduction: Physical activity (PA) during pregnancy has numerous benefits, which may be mediated via effects on the immune system. However, supportive evidence is inconsistent and is mainly from studies in high-risk groups. We estimated the effect of PA during pregnancy on systemic inflammatory markers and cytokines in mothers recruited in the Barwon infant study.

The association between device-measured sitting time and cardiometabolic health risk factors in children.

Background: There is limited evidence of the associations between postural-derived sitting time, waist-worn derived sedentary time and children's health and the moderation effect of physical activity (PA). This study examined associations of children's device-measured sitting time with cardiometabolic health risk factors, including moderation by physical activity.

Methods: Cross-sectional baseline data from children (mean-age 8.

Fathers' perceived role, self-efficacy and support needs in promoting positive nutrition and physical activity in the first 2000 days of life: a mixed methods study.

Background: The first 2000 days of life are a crucial and opportunistic time to promote positive dietary and physical activity behaviours that can continue throughout life. The bulk of research on the impact of parents promoting positive dietary and physical activity behaviours has been on mothers, with the impact of fathers rarely investigated. The aim of this study is to investigate fathers' perceived role, self-efficacy and support needs in promoting positive dietary and physical activity behaviours in early childhood.

Cost-effectiveness of reducing children's sedentary time and increasing physical activity at school: the Transform-Us! intervention.

Background: Improving physical activity and reducing sedentary behavior represent important areas for intervention in childhood in order to reduce the burden of chronic disease related to obesity and physical inactivity in later life. This paper aims to determine the cost-effectiveness of a multi-arm primary school-based intervention to increase physical activity and/or reduce sedentary time in 8-9 year old children (Transform-Us!).

Methods: Modelled cost-utility analysis, using costs and effects from a cluster randomized controlled trial of a 30-month intervention that used pedagogical and environmental strategies to reduce and break up sedentary behaviour (SB-I), promote physical activity (PA-I), or a combined approach (PA + SB-I), compared to current practice.

Priority populations' experiences of the accessibility and inclusion of recreation centres: a qualitative study.

Background: Although the health benefits of physical activity are well documented, certain priority populations are often disproportionately insufficiently active and at higher risk of poor health. Recreation centres have the potential to provide accessible and supportive environments for physical activity for all. However, little is known about priority populations' experiences of these venues and their views of how accessibility and inclusion can be optimised.

Prevalence of toddlers meeting 24-hour movement guidelines and associations with parental perceptions and practices.

Objectives: Whether toddlers (1-2 years) meet 24-hour Movement Guidelines and how parental practices and perceptions are related to compliance are uncertain. This study: a) estimated the proportion of toddlers meeting individual and combined movement guidelines; and b) examined associations between parental perceptions/practices and toddlers' compliance with movement guidelines.

Design: Cross-sectional study.

Are physical activity and sleep associated with emotional self-regulation in toddlers? a cross-sectional study.

Background: Toddlerhood (2-3 years) is a crucial period for the development of physical activity, sleep, and emotional self-regulation skills. Although there is growing evidence of positive associations between physical activity, sleep, and emotional self-regulation in school-aged children, the associations in toddlers remain unclear. Thus, this study aimed to examine the association between physical activity, sleep, and emotional self-regulation in toddlers.

Examination of Physical Activity, Organized Sport, and Sitting Time Among Women and Mothers From Culturally and Linguistically Diverse Backgrounds.

Background: Little evidence is available from culturally and linguistically diverse (CALD) communities on the association between motherhood and physical activity (PA). This study aimed to examine independent and joint associations of cultural background and motherhood with meeting PA guidelines, participation in organized sports, and high sitting time (>8 h/d).

Methods: We used self-reported cross-sectional data from survey 8 of the 1973-1978 cohort of the Australian Longitudinal Study on Women's Health.

Association between physical activity and self-regulation in early childhood: A systematic review.

Physical activity and self-regulation are important predictors of pediatric overweight and obesity. Young children (0-5 years) with lower physical activity levels and poorer self-regulation skills are at greater risk for overweight. Despite growing evidence that the two constructs are interrelated, their association remains unclear in young children.

An umbrella review of the benefits and risks associated with youths' interactions with electronic screens.

The influence of electronic screens on the health of children and adolescents and their education is not well understood. In this prospectively registered umbrella review (PROSPERO identifier CRD42017076051 ), we harmonized effects from 102 meta-analyses (2,451 primary studies; 1,937,501 participants) of screen time and outcomes. In total, 43 effects from 32 meta-analyses met our criteria for statistical certainty.

Fussy Eating Rescue, a mobile-web app for responsive feeding practises among parents of toddlers: protocol for a pilot randomised controlled feasibility trial.

Background: Fussy eating is most often a developmentally typical behaviour, generally presenting during toddlerhood. However, up to half of parents of young children are concerned about fussy eating, and this concern may mediate the use of nonresponsive feeding practises, such as coercive or unstructured feeding and using food to reward eating. Despite the high prevalence of parental concern for fussy eating and the negative impacts nonresponsive feeding practises have on children's health and diets, no previous digital intervention to improve the feeding practises of parents of toddlers concerned about fussy eating has been evaluated.

Cross-sectional and prospective associations between behavioural patterns and adiposity in school-aged children.

Objective: Behavioural patterns are important in understanding the synergistic effect of multiple health behaviours on childhood adiposity. Most previous evidence assessing associations between patterns and adiposity were cross-sectional and investigated two or three behaviour domains within patterns. This study aimed to identify behavioural patterns comprising four behaviour domains and investigate associations with adiposity risk in children.

Understanding the pathways between prenatal and postnatal factors and overweight outcomes in early childhood: a pooled analysis of seven cohorts.

Background/objectives: Childhood overweight and obesity are influenced by a range of prenatal and postnatal factors. Few studies have explored the integrative pathways linking these factors and childhood overweight. This study aimed to elucidate the integrative pathways through which maternal pre-pregnancy body mass index (BMI), infant birth weight, breastfeeding duration, and rapid weight gain (RWG) during infancy are associated with overweight outcomes in early childhood from ages 3 to 5 years.

Factors contributing to the sustained implementation of an early childhood obesity prevention intervention: The .

Background: The is an efficacious, group-based program for first-time parents, delivered at three-monthly intervals when are aged 3-18 months through an existing universal care service in Victoria, Australia. Many lessons have been learnt from its origins as a cluster randomized control trial to its small-scale, community-level implementation. This study aimed to describe factors contributing to its sustained implementation to inform large-scale implementation across Australia.

Mapping intervention components from a randomized controlled trial to scale-up of an early life nutrition and movement intervention: The INFANT program.

Introduction: Early life parent-focused interventions can effectively improve infant and child nutrition and movement (physical activity and sedentary behavior) as well as parents' health behaviors. Scale-up of such interventions to real-world settings is essential for population-wide benefits. When progressing to scale-up, intervention components may be modified to reflect contextual factors and promote feasibility of scale-up.

Outdoor time, screen time and sleep reported across early childhood: concurrent trajectories and maternal predictors.

Background: Understanding the developmental trajectories of outdoor time, screen time and sleep is necessary to inform early interventions that promote healthy behaviours. This study aimed to describe concurrent trajectories of outdoor time, screen time and sleep across the early childhood period and their maternal predictors.

Methods: Data across five time points at child age 4, 9, 19, 42 and 60 months from the INFANT intervention were analysed.

Adherence to Canadian 24-Hour Movement Guidelines among infants and associations with development: a longitudinal study.

Background: To examine: 1) longitudinal adherence to the Canadian 24-Hour Movement Guidelines in a sample of infants and 2) associations between adherence to the guidelines over time and development.

Methods: Participants were 250 parent-infant dyads from the Early Movers project in Edmonton, Alberta. At 2, 4, and 6 months of age, physical activity, sedentary behaviour, sleep, and development were measured with a parental questionnaire that included items from the Ages & Stages Questionnaire (ASQ-3).

Accelerometer-based osteogenic indices, moderate-to-vigorous and vigorous physical activity, and bone traits in adolescents.

Objectives: We investigated the associations of accelerometry-derived osteogenic indices (OIs), moderate-to-vigorous (MVPA), and vigorous intensity physical activity (VPA) with peripheral quantitative computed tomography (pCQT) parameters in 99 adolescents aged 10-13 years.

Methods: Bone parameters were assessed at the distal (4%) and shaft (66%) of the tibia using pQCT. Accelerometers were worn on the right hip for 7 consecutive days.

Mothers as advocates for healthier lifestyle behaviour environments for their children: results from INFANT 3.5-year follow-up.

Background: The amount of time children spend outside of their home environment has increased over the past decades. Therefore, the quality of the health behaviour environments where young children spend time is likely to impact their health behaviour opportunities. The aim of this study was to describe the proportion of mothers who consider it possible to make changes in their local communities to increase opportunities for children to eat healthily, be physically active, and limit screen time exposure, as well as the proportion who have attempted to do so.
