Inequities in child protective services contact among First Nations and non-First Nations parents in one Canadian province: A retrospective population-based study
CPS contact was high among parents and prevalence was almost 4 times higher among First Nations parents, where 1 out of 2 were intervened upon by CPS. Findings reinforce significant concerns about the system's scope and the crucial importance of considering its role in compounding health inequities and sustaining colonialism in Canada. First Nations-led interventions are needed to reduce CPS disruption to the lives of First Nations peoples

An unconditional prenatal cash benefit is associated with improved birth and early childhood outcomes for Metis families in Manitoba, Canada
A cash benefit was associated with better birth outcomes for low-income Metis families. • Among families who received the benefit, there were fewer low birth weight and preterm births. • Children in families who received the benefit were more likely to be fully vaccinated by age 2. In Manitoba, low-income pregnant women are eligible for the Healthy Baby Prenatal Benefit (HBPB), which provides up to CAD $81.41/month during the second and third tri…
Differential effects of a school‐based obesity prevention program: A cluster randomized trial
School-based healthy living interventions are widely promoted as strategies for preventing obesity. The peer-led Healthy BuddiesTM curriculum has been shown to improve obesity-related outcomes in school-aged children. We examined whether these improvements existed among subgroups of children stratified by sex, income level and urban/rural geography. In a cluster-randomized controlled trial, elementary schools in Manitoba, Canada, were randomly al…
The association of a paraprofessional home visiting intervention with lower child maltreatment rates in First Nation families in Canada: A population-based retrospective cohort study
Sex differences in the socioeconomic gradient of children's early development
Sex differences in early child development (ECD) are well documented, as is the socioeconomic status (SES) gradient in early development outcomes. However, relatively little is known about whether the SES gradient in ECD outcomes varies by sex. This study examines whether the association between neighbourhood SES and developmental health outcomes of Canadian kindergarten children is different for girls than for boys. Individual-level child develo…

Changes in Caregiver Health in the Years Surrounding the Birth of a Child With Health Problems: Administrative Data From British Columbia
BACKGROUND: Caregivers of children with health problems (CHPs; usually mothers) experience more physical and psychological health problems than those of children without health problems (non-CHPs). Primarily cross-sectional and survey-driven, this literature has not yet explored whether these health differences existed before the birth of the CHPs, or are exacerbated postbirth. METHODS: Using linked administrative health data on all mother-child …

Children's understanding of referential messages produced by deaf and hearing speakers
Children 4 to 10 years of age were presented with referential messages that varied in message adequacy and speech quality and were required to choose the intended referent from a set of four alternatives. Follow ing feedback regarding their choice, they evaluated the message as good or bad and provided reasons for their evaluation. Half of the messages had sufficient information to define the referent uniquely; half had insufficient or ambiguous …
The Unintended and Unexpected Impact of Downsizing: Costly Hospitals Become More Costly
OBJECTIVES: In this project we assessed the impact of 1992 budget cuts ($50 million, or approximately 7% of urban hospitals' budgets) on the relative costliness of Manitoba's hospitals. The cuts targeted the teaching hospitals, those institutions we had found to be particularly costly in a previous Manitoba Centre for Health Policy and Evaluation study. RESULTS: Unexpectedly, we found that because budget cuts were smaller proportionately than the…
A Comparative Study of the Costliness of Manitoba Hospitals
OBJECTIVES: In light of ongoing discussions about health care policy, this study offered a method of calculating costs at Manitoba hospitals that compared relative costliness of inpatient care provided in each hospital. RESEARCH DESIGN: This methodology also allowed comparisons across types of hospitals-teaching, community, major rural, intermediate and small rural, as well as northern isolated facilities. MEASURES: Data used in this project incl…
Managing Health Services: How the Population Health Information System (Populis) Works for Policymakers
OBJECTIVES: University-based researchers in Manitoba, Canada, have used administrative data routinely collected as part of the national health insurance plan to design an integrated database and population-based health information system. This information system is proving useful to policymakers for answering such questions as: Which populations need more physician services? Which need fewer? Are high-risk populations poorly served? or do they ha…
Monitoring the Impact of Hospital Downsizing on Access to Care and Quality of Care
The most recent data used for monitoring the potential effects of bed closures in Winnipeg hospitals since 1992/93 found that despite downsizing, access to care was by no means compromised. Just as many patients were cared for in 1995/96 as in 1991/92. Changes in patterns of care included more outpatient and fewer inpatient surgeries, and a decrease in the number of hospital days. The number of high-profile surgical procedures, such as angioplast…

Does a pay-for-performance program for primary care physicians alleviate health inequity in childhood vaccination rates
The P4P program had a limited impact on vaccination rates and did not address health inequity
Can opportunities be enhanced for vaccinating children in home visiting programs? A population-based cohort study
Home visiting programs have the potential to increase vaccination rates for children enrolled, despite limited program content directed towards this end. Evidence-based program enhancements have the potential to increase these rates further, however more research is needed to inform policy makers of optimal approaches in this regard, especially with respect to cost-effectiveness
