Risk factors for delayed social-emotional development and behavior problems at age two: Results from the All Our Babies/Families (AOB/F) cohort.

Background And Aims: Social-emotional delays and behavioral problems at preschool age are associated with negative outcomes at school age, including ongoing behavior problems, poorer social functioning, and academic difficulties. Understanding modifiable risk factors for suboptimal development requires consideration of contemporary family circumstances to determine areas for effective early intervention to optimize development. This study aimed to identify risk factors for delayed social-emotional development and behavior problems at age two among participants of the All Our Babies/Families cohort study.

Protective factors for child development at age 2 in the presence of poor maternal mental health: results from the All Our Babies (AOB) pregnancy cohort.

Objective: To identify the combination of factors most protective of developmental delay at age 2 among children exposed to poor maternal mental health.

Design: Observational cohort study.

Setting: Pregnant women were recruited from primary healthcare offices, the public health laboratory service and community posters in Calgary, Alberta, Canada.

All Our Babies Cohort Study: recruitment of a cohort to predict women at risk of preterm birth through the examination of gene expression profiles and the environment.

Background: Preterm birth is the leading cause of perinatal morbidity and mortality. Risk factors for preterm birth include a personal or familial history of preterm delivery, ethnicity and low socioeconomic status yet the ability to predict preterm delivery before the onset of preterm labour evades clinical practice. Evidence suggests that genetics may play a role in the multi-factorial pathophysiology of preterm birth.

Risk factors for cessation of breastfeeding prior to six months postpartum among a community sample of women in Calgary, Alberta.

Objectives: To describe the rates of breastfeeding initiation and breastfeeding for at least six months and identify risk factors for failing to breastfeed for six months among a community sample of mothers in Calgary, Alberta.

Methods: A cohort of women (n=1737) who participated in a longitudinal study of prenatal support and who could be contacted when their child was three-years-old (n=1147) were invited to participate in a follow-up telephone questionnaire. Of these 1147 women, 780 (69% participating rate) participated and provided breastfeeding data.
