Maternal chronic disease and breastfeeding outcomes: a Canadian population-based study.

Background: The prevalence of chronic disease in pregnant women has consistently risen over the past two decades. Substantial evidence demonstrates that maternal chronic disease is associated with adverse medical outcomes like preterm birth, but less research has characterized postpartum outcomes such as infant feeding practices. It is recommended that infants be exclusively breastfed from birth to 6 months given the numerous health benefits it provides.

Pregnancy complications and risk of preterm birth according to maternal age: A population-based study of delivery hospitalizations in Alberta.

Introduction: Pregnancy-related medical complications are associated with a 2- to 5-fold increased risk of preterm birth (PTB), but the nature of this etiologic relation in context with maternal factors remains poorly understood. Previous studies have generally treated maternal age as a confounder but overlooked its potential as an effect modifier, whereby the magnitude of the effect of complications on PTB could differ significantly across age groups. We investigated whether advanced maternal age (≥35 years) modified the association between pregnancy complications and PTB, and compared population-attributable fractions of PTB from complications in women older vs younger than 35 years.

National Analysis of Risk Assessment Content in Prenatal Records Across Canada.

Each Canadian province/territory has a distinct prenatal record form to guide maternity health care. Because there is no national oversight of these forms, little is known about how they compare regarding content on risk assessment for adverse perinatal outcomes. We cataloged and compared the risk factors that are captured on prenatal record forms across Canada.

The effect of skin-to-skin care on postpartum depression among mothers of preterm or low birthweight infants: A systematic review and meta-analysis.

Background: Mothers of preterm or low birthweight (LBW) infants are at two to three times greater risk of postpartum depression (PPD) than mothers of healthy infants, which may be partially due to mother-infant separation during hospitalization. Skin-to-skin care could protect against PPD among these vulnerable mothers. We examined the effect of skin-to-skin care on PPD among mothers of preterm or LBW infants through a systematic review and meta-analysis.

Administration of epidural labor analgesia is not associated with a decreased risk of postpartum depression in an urban Canadian population of mothers: a secondary analysis of prospective cohort data.

Background: Postpartum depression (PPD) is a common complication of pregnancy, affecting approximately 13% of mothers internationally. Previous research has examined whether epidural analgesia used for pain control during labor and birth is associated with a lower risk of PPD, but reports conflicting results and may have suffered from methodological shortcomings. Our study aimed to prospectively assess whether epidural analgesia is associated with a lower risk of PPD (at either 6 weeks or 6 months postpartum) after attempting to adequately adjust for selection bias and confounding variables.

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.
