Background
• Early life experiences set the stage for lifelong health and wellbeing
• Early childhood development begins before conception and can
impact development of chronic diseases, neurodevelopment, school
performance, and behaviors
• In Ontario, there is currently a lack of comprehensive knowledge
regarding the clustering of risk in postpartum population

OBJECTIVE
To examine the clustering of risk factors in postpartum
families in Ontario

Methods: Data
Healthy Babies Healthy Children
• Foundational program by the Ministry of Children and Youth Services
(MCYS) introduced in 1998. Recent enhancements introduced in 2013
• Designed to help children in Ontario have a healthy start in life and reach
their full potential
• Implemented in all 36 public health units
• Universal screening (HBHC Screen) with targeted services for vulnerable
families
• In 2013/14, at the request of MCYS, PHO accessed HBHC-IRSS to undertake
a process implementation evaluation of the renewed HBHC program
• Cluster analysis was completed as an add-on to the HBHC evaluation

Methods: Sample
• Screened HBHC postpartum population in Ontario
• Families with infants from birth to 6 weeks of age
• Recruited in the first six months of implementation of the enhanced program
• Feb 2013-Oct 2013 (staggered implementation)
• Screen data entered by staff into HBHC-ISCIS; extracted from HBHC-IRSS
database by PHO HBHC evaluation epidemiologist
• Exclusion criteria:
•
•
•
Families with infants over 6 weeks of age
Non-HBHC clients
Families with missing HBHC Screen data who did not receive HBHC services
• Final sample included 56,903 infants
• Provides a good perspective of Ontario’s postpartum population because this
represents over 80% of provincial births
PublicHealthOntario.ca

Methods: Indicators
• HBHC Screen has 36 items:
• Pregnancy and birth
• (i.e., birth-weight, multiple births, premature, Apgar score, labor and delivery
complications)
• Socio-demographics (family)
• (i.e., age, educational attainment, access to OHIP, concerns about money)
• Infant/child
• (i.e., congenital or acquired health challenge )
• Risk behaviours during pregnancy
• (i.e., smoking, alcohol use, drug use)
• Parenting and parenting-related
• (i.e., parenting concerns, history of depression/anxiety/mental illness in
parent(s))
• Other infant/child development risk factors

Methods: Analysis
• Tetrachoric correlations were used to create a matrix of association
among screen questions
• Exploratory cluster analysis was used to identify risk profile
• Agglomerative hierarchical clustering
• Visual representation using dendrogram
• Average distance was used to determine clusters
• All analyses were preformed using SAS 9.3
• Ethics approval was obtained from Public Health Ontario’s Ethics
Review Board (ERB)

Results
• 69% of the population belonged to one of the three clusters; the remaining 31%
had no risk factor identified (screen score = 0)
• Similar percentages were identified in pregnancy, labor, and delivery cluster (42%)
and socio-demographic, behavioural, and parenting cluster (41%)
• Approximately 1 in 5 infants (19%) belonged to both cluster#1 and cluster #2
31% (no identified cluster)
Cluster #1:

and delivery

Limitations
• The dataset is not complete for all postpartum families in
Ontario
• Those who did not consent for screening, were missed by the program,
or participated in the Aboriginal HBHC were not included
• Not all risk factors for child health development were
examined (e.g., physical environment of the home, nutrition)
• Risk factor information was self-reported by families to staff
performing screening
• Not all 36 questions were answered on the HBHC Screen
• Sensitive questions had higher rate of non-response
• This will likely contribute to the underestimation of these risk factors to
the clusters
PublicHealthOntario.ca

Conclusion
• Based on 36 medical, socioeconomic, and parenting risk
factors three clusters were identified
• There appears to be a separate cluster of postpartum clients
with pregnancy and labour/delivery related risk factors
• Burden of socio-demographic, behavioural, and parenting risk
factors appear to be similar to that of pregnancy and
labour/delivery related risk factors
• Risk factors in the postpartum population are linked and these
will likely impact program planning and delivery for this
population
