Preschool children’s physical activity in the home, childcare and neighbourhood environment: A latent profile analysis using device-based measuresBased on the socioecological conceptual model, the physical environment within the home, childcare and neighbourhood domains are key factors that influence preschool children's physical activity; however, the relative importance of each of these domains for preschool children's physical activity is unclear.

Developmental trends in young children’s device-measured physical activity and sedentary behaviourKnowledge of developmental trends in meeting age-specific 24-hour movement behaviour guidelines is lacking. This study describes developmental trends in device-measured physical activity and sedentary time over a three-year period among Western Australian children aged two to seven years, including differences between boys and girls.

Mapping Lung Hematopoietic Progenitors: Developmental Kinetics and Response to Influenza A InfectionThe bone marrow is a specialised niche responsible for the maintenance of hematopoietic stem and progenitor cells during homeostasis and inflammation. Recent studies however have extended this essential role to the extramedullary and extravascular lung microenvironment. Here, we provide further evidence for a reservoir of hematopoietic stem and progenitor cells within the lung from embryonic day 18.5 until adulthood.

Determinants of lung function development from birth to age 5 years: an interrupted time series analysis of a South African birth cohortEarly life is a key period that determines long-term health. Lung development in childhood predicts lung function attained in adulthood and morbidity and mortality across the life course. We aimed to assess the effect of early-life lower respiratory tract infection (LRTI) and associated risk factors on lung development from birth to school age in a South African birth cohort.

Developmental trajectories of socio-emotional outcomes of children and young people in out-of-home care – Insights from data of Pathways of Care Longitudinal Study (POCLS)There has been a limited understanding of the longitudinal trajectory and determinants of socio-emotional outcomes among children in out-of-home care (OOHC). This study aimed to examine child socio-demographics, pre-care maltreatment, placement, and caregiver factors associated with trajectories of socio-emotional difficulties of children in OOHC.

Gender differences in time allocation contribute to differences in developmental outcomes in children and adolescentsUsing over 50 thousand time-use diaries from two cohorts of children, we document significant gender differences in time allocation in the first 16 years in life. Relative to males, females spend more time on personal care, chores and educational activities and less time on physical and media related activities. These gender gaps in time allocation appear at very young ages and widen overtime.

Perceptions of a family-based lifestyle intervention for children with overweight and obesity: a qualitative study on sustainability, self-regulation, and program optimizationFamily-based lifestyle interventions (FBLIs) are an important method for treating childhood weight problems. Despite being recognized as an effective intervention method, the optimal structure of these interventions for children’s overweight and obesity has yet to be determined.

Changes in airway inflammation with pseudomonas eradication in early cystic fibrosisNeutrophil elastase is a significant risk factor for structural lung disease in cystic fibrosis, and Pseudomonas aeruginosa airway infection is linked with neutrophilic inflammation and substantial respiratory morbidity. We aimed to evaluate how neutrophil elastase (NE) activity changes after P. aeruginosa eradication and influences early disease outcomes. We assessed participants in the AREST CF cohort between 2000 and 2018 who had P. aeruginosa cultured from their routine annual bronchoalveolar lavage (BAL) fluid and who underwent eradication treatment and a post eradication BAL. Factors associated with persistent P. aeruginosa infection, persistent neutrophilic inflammation following eradication and worse structural lung disease one year post-eradication were evaluated.

Clinician-rated quality of video otoscopy recordings and still images for the asynchronous assessment of middle-ear diseaseVideo otoscopy plays an important role in improving access to ear health services. This study investigated the clinician-rated quality of video otoscopy recordings and still images, and compared their suitability for asynchronous diagnosis of middle-ear disease. Two hundred and eighty video otoscopy image-recording pairs were collected from 150 children (aged six months to 15 years) by an ear, nose, and throat (ENT) specialist, audiologists, and trained research assistants, and independently rated by an audiologist and ENT surgeon.

Looking beyond: complex holistic care needs of Syrian and Iraqi refugee children and adolescentsProtracted international conflict has seen escalating numbers of displaced and resettled Syrian and Iraqi refugees, raising concerns for their health and well-being. This paper describes the demographic and clinical profiles of recently resettled Syrian and Iraqi refugee children and adolescents across physical, psychosocial, developmental and educational domains using standardised multidisciplinary assessments.
