School food programs and food insecurity at the Reach school network
Our study highlights the complex relationship between food insecurity and school food program participation among an at-risk, urban children. Future research is needed, with larger sample sizes and longitudinal designs to better understand these complex relationships

Children’s screen use and school readiness at 4-6 years
Screen use in early childhood is associated with increased vulnerability in developmental readiness for school, with increased risk for poorer language and cognitive development in kindergarten, especially among high users
Mealtime media use and cardiometabolic risk in children
Objectives: To examine the association between mealtime media use and non-HDL-cholesterol as well as other markers of cardiometabolic risk (CMR) in children. Design: A repeated measures study design was used to examine the association between mealtime media use and CMR outcomes. Multivariable linear regression with generalised estimating equations was used to examine the association between mealtime media use and CMR outcomes. Analyses were strat…
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 …
Income and neighbourhood deprivation in relation to obesity in urban dwelling children 0–12 years of age
BACKGROUND: Childhood obesity is a major public health concern. This study evaluated the independent and joint associations of family-level income, neighbourhood-level income and neighbourhood deprivation, in relation to child obesity. METHODS: A cross-sectional study was conducted in children ≤12 years of age from TARGet Kids! primary care network (Greater Toronto Area, 2013-2019). Parent-reported family income was compared with median neighbour…
Delay in childhood vaccinations during the Covid-19 pandemic
Nutritional risk in early childhood and parent-reported school concerns
Objective: To determine if nutritional risk in early childhood is associated with parent-reported school concerns. Design: A prospective cohort study conducted through the TARGet Kids! primary care research network (2011–2018). Nutritional risk was measured between 18 months and 5 years of age using validated parent-completed NutriSTEP ® questionnaires with eating behaviour and dietary intake subscores (0 = lowest and 68 = highest total nutrition…
Age of cow milk introduction and growth among 3–5-year-old children
Objective: To evaluate the association between the age of cow milk introduction and childhood growth. Design: A secondary analysis of a prospective cohort study. Setting: Toronto, Canada. Participants: Healthy children z -score. Secondary outcomes were volume of cow milk consumed (cups/d) and BMI z -score. Outcomes were measured at the last visit before 5 years of age. Multiple linear regression was used to examine these relationships. Results: A…
Public health preventive measures and child health behaviours during Covid-19
Public health preventive measures during COVID-19 were associated with a negative impact on the health behaviours of Canadian children living in a large metropolitan area
The social determinants of health as predictors of adherence to public health preventive measures among parents and young children during the Covid-19 pandemic
Parenting stress during infancy is a risk factor for mental health problems in 3-year-old children
Healthy preschool-aged children with parents reporting parenting stress during infancy had a 2 times higher odds of mental health problems at 3 years
Whole milk compared with reduced-fat milk and childhood overweight
A qualitative study to understand parent and physician perspectives about cow’s milk fat for children
Objective: Consensus guidelines recommend that children consume reduced-fat (0·1–2 %) cow’s milk at age 2 years to reduce the risk of obesity. Behaviours and perspectives of parents and physicians about cow’s milk fat for children are unknown. Objectives were to: (i) understand what cow’s milk fat recommendations physicians provide to 2-year-old children; (ii) assess the acceptability of reduced-fat v . whole cow’s milk in children’s diets by par…
Severe obesity in children 17 to 24 months of age
Hydroxyvitamin D supplementation and health-service utilization for upper respiratory tract infection in young children
Objective Upper respiratory tract infections (URTI) are the most common and costly condition of childhood. Low vitamin D levels have been hypothesized as a risk factor for URTI. The primary objective was to determine if serum vitamin D levels were associated with health-service utilization (HSU) for URTI including hospital admission, emergency department visits and outpatient sick visits. The secondary objectives were to determine whether oral vi…
Difficulty buying food, BMI, and eating habits in young children
Severe iron-deficiency anaemia and feeding practices in young children
Objectives Fe-deficiency anaemia (IDA) occurs in 1–2 % of infants in developed countries, peaks at 1–3 years of age and is associated with later cognitive deficits. The objectives of the present study were to describe the characteristics of young children with severe IDA and examine modifiable risk factors in a developed-country setting. Design Two prospective samples: a national surveillance programme sample and a regional longitudinal study sam…
Total Duration of Breastfeeding, Vitamin D Supplementation, and Serum Levels of 25-Hydroxyvitamin D
Objectives. To determine the association between total breastfeeding duration and serum 25-hydroxyvitamin D (25-OHD) and to explore whether vitamin D supplementation influences this association. Methods. We conducted a cross-sectional study of healthy children between September 2011 and August 2013 through the TARGet Kids! primary health care research network. Of the 4533 eligible children, we included only the 2508 who had 25-OHD measured. We as…
Parents' perception of stroller use in young children
This study provides a context for researchers and policy makers to consider when developing stroller related physical activity guidelines for young children
Housing and Sexual Health Among Street-Involved Youth
Mandatory labeling requirements and over-the-counter cough and cold medication use in early childhood
Non-Western immigrant children have lower 25-hydroxyvitamin D than children from Western families
Objective To determine if children aged 1–6 years from non-Western immigrant families have lower serum 25-hydroxyvitamin D (25(OH)D) levels than children from Western-born families and examine which factors influence this relationship. Design Cross-sectional study. Setting Toronto, Canada. Subjects Healthy children ( n 1540) recruited through the TARGet Kids! practice-based research network. Serum 25(OH)D concentrations of non-Western immigrants …

Parental factors associated with screen time in pre-school children in primary-care practice
Objective To identify child and parental factors associated with screen time in 3-year-old children. Design Observational study. Setting Participants were recruited from a large primary-care paediatric group practice in Toronto, Canada. Subjects Healthy 3-year-old children were included. A questionnaire was completed by their parents on screen time. Descriptive statistics and linear regression models were used to assess associations between child…
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…
