The influence of paternal preconception health on birth defects and head circumference
While paternal environmental exposures and lifestyle factors can influence sperm epigenetic states and affect fetal development, this area of research remains relatively underexplored. This comprehensive scoping review aimed to identify, compile, and analyze the literature on paternal preconception health and its impact on fetal development, specifically related to congenital birth defects (CBDs) and head circumference. We conducted a scoping rev…
Outcome measurement instruments used to measure diet-related outcomes in infancy
INTRODUCTION: Supporting positive diet behaviours during infancy is essential to support child health and prevent childhood obesity. How infant diet-related outcomes are measured in trials is crucial to determining intervention effectiveness. This scoping review examined what and how outcome measurement instruments are currently used to measure 13 infant diet-related outcomes from a previously developed core outcome set. METHODS: The databases EM…
Influential Factors on Participation in Mental Health Research
Parental employment quality and the mental health and school performance of children and youth
BACKGROUND: Lower-quality employment, characterised by excessive or part-time hours, irregular schedules and inadequate earnings, is a key social determinant of health among adults. Research examining parental employment quality in relation to the mental health and school performance of children is lacking. The study objective was to measure the associations between parental employment quality and child mental health symptoms and school performan…
Uptake and cardiac events of Covid-19 vaccinations among Canadian youth and young adults
Few studies have examined population-level data of the COVID-19 original and bivalent vaccine on its uptake and potential side effects. We used population-based health administrative data from Jan 2021–Feb 2023 to identify Ontario residents aged 12–35 years old to calculate their rates of COVID-19 vaccine uptake and vaccine-related cardiac events (myocarditis and pericarditis). Multivariable Cox, logistic, and negative binomial regression analyse…
Maternal postnatal depressive symptoms and early achievement of developmental milestones in infants and young children
Screening for social determinants of health, including maternal depression, is a recommended pediatric practice. However, the magnitude of association between maternal and child screening tools remains to be determined. The current study evaluated the association between maternal postnatal depressive symptoms and child developmental milestones, as well as moderators of these associations. A comprehensive search strategy was carried out in four da…

Despite significant disruption to school during the COVID-19 pandemic, research on the impact on children is sparse. This study examines in-person and virtual learning contexts and the impact of school format on mental health (MH). Children and adolescents were recruited from community and clinical settings. Parents and children completed prospective online surveys about school experiences (November 2020) and MH symptoms (February/March 2021), in…
Vulnerability pathways to mental health outcomes in children and parents during Covid-19
We examined pathways from pre-existing psychosocial and economic vulnerability to mental health difficulties and stress in families during the COVID-19 pandemic. Data from two time points from a multi-cohort study initiated during the COVID-19 pandemic were used. Parents of children 6–18 years completed questionnaires on pre-COVID-19 socioeconomic and demographic factors in addition to material deprivation and stress due to COVID-19 restrictions,…

Population-Based Teacher-Rated Assessment of Anxiety Among Canadian Kindergarten Children
Despite anxiety being a prevalent mental health problem in children, little data exist on the pervasiveness and levels of anxiety symptoms in kindergarteners. Data from the Early Development Instrument, a teacher-completed, population-level measure of child development, were collected across Canada from 2004 to 2015. The final analytic sample consisted of 974,319 children of whom 2.6% were classified as "highly anxious". Compared to children who …

Paediatric Obesity Research in Early Childhood and the Primary Care Setting
Primary paediatric health care is the foundation for preventative child health. In light of the recent obesity epidemic, paediatricians find themselves at the frontline of identification and management of childhood obesity. However, it is well recognized that evidence based approaches to obesity prevention and subsequent translation of this evidence into practice are critically needed. This paper explores the role of primary care in obesity preve…
