Background: Socioeconomic status (SES) is an important determinant of health and potential modifier of the effects of environmental contaminants. There has been a lack of comprehensive indices for measuring overall SES in Canada. Here, a more comprehensive SES index is developed aiming to support future studies exploring health outcomes related to environmental pollution in Canada. Methods: SES variables (n=22, Census Canada 2006) were selected based on: cultural identities, housing characteristics, variables identified in Canadian environmental injustice studies and a previous deprivation index (Pampalon index). Principal component analysis with a single varimax rotation (factor loadings=¦60¦) was performed on SES variables for 52974 census dissemination areas (DA). The final index was created by averaging the factor scores per DA according to the three components retained. The index was validated by examining its association with preterm birth (gestational age<37 weeks), term low birth weight (LBW, <2500 g), small for gestational age (SGA, <10 percentile of birth weight for gestational age) and PM2.5 (particulate matter=2.5 µm) exposures in Edmonton, Alberta (1999–2008). Results: Index values exhibited a relatively normal distribution (median=0.11, mean=0.0, SD=0.58) across Canada. Values in Alberta tended to be higher than in Newfoundland and Labrador, Northwest Territories and Nunavut (Pearson chi-square p<0.001 across provinces). Lower quintiles of our index and the Pampalon’s index confirmed know associations with a higher prevalence of LBW, SGA, preterm birth and PM2.5 exposure. Results with our index exhibited greater statistical significance and a more consistent gradient of PM2.5 levels and prevalence of pregnancy outcomes. Conclusions: Our index reflects more dimensions of SES than an earlier index and it performed superiorly in capturing gradients in prevalence of pregnancy outcomes. It can be used for future research involving environmental pollution and health in Canada.

IntroductionIn Canada, rates of congenital syphilis have been increasing rapidly in recent years, following a surge in infectious syphilis. These trends call for a closer look at missed opportunities for testing, diagnosis, treatment, and follow-up of pregnant individuals. The epidemiological situation is especially serious given that effective treatment is available for syphilis during pregnancy and that congenital syphilis is a preventable outcome that engenders adverse birth outcomes such as miscarriage, stillbirth, and neonatal death as well as potentially lifelong ocular, neurological, hepatosplenic, and musculoskeletal sequelae. The objective of this study is to examine the factors associated with congenital syphilis trends and to highlight promising initiatives and programs across the country committed to addressing these trends.MethodsA literature review with a focus on Canadian studies was conducted to identify factors that may be driving the continued increase in early congenital syphilis rates over the past decade. An environmental scan of initiatives and programs providing syphilis care and support was also conducted.ResultsKey factors identified in association with congenital syphilis outcomes included a lack of timely and repeated prenatal syphilis screening, inadequate prenatal treatment and follow-up of syphilis infection, barriers to accessing prenatal care caused by multiple intersecting social determinants of health as well as by certain structural determinants of health, and substance use. A number of initiatives to improve syphilis care within the health care system and several community-based programs filling in some of the gaps in syphilis care and support are making important advances in addressing the epidemiological situation with syphilis.DiscussionMuch work is underway at various levels of government and local community to address the situation. Key recommendations for maximizing impact in curbing infectious and congenital syphilis rates include the following: planning an integrated strategy for addressing sexually transmitted and blood-borne infections as a whole; adopting a more holistic approach to improving health and wellbeing; developing targeted interventions for addressing structural and social barriers to health equity; and taking a collaborative approach to response by involving multilevel stakeholders, such as key populations, community groups, health care providers, and public health authorities.

The Canadian Community Health Survey (CCHS) is a cross-sectional survey that collects information related to health status, health care utilization and health determinants for the Canadian population. The CCHS operates on a two-year collection cycle. The first year of the survey cycle l.1 is a large sample, general population health survey, designed to provide reliable estimates at the health region level. The second year of the survey cycle l.2 is a smaller survey designed to provide provincial level results on specific focused health topics. This Microdata File contains data collected in the third year of collection for the CCHS (Cycle 2.1). Information was collected between January 2003 and December 2003, for 126 health regions, covering all provinces and territories. The CCHS (Cycle 2.1) collects responses from persons aged 12 or older, living in private occupied dwellings. Excluded from the sampling frame are individuals living on Indian Reserves and on Crown Lands, institutional residents, full-time members of the Canadian Armed Forces, and residents of certain remote regions. The CCHS covers approximately 98% of the Canadian population aged 12 and over.

Biomonitoring provides a measure of internal doses of environmental chemicals or agents and allows for a more accurate measure of human health risk from these exposures. In these Alberta Biomonitoring Program datasets, information was collected as part of 3 province-wide studies investigating the serum levels of environmental chemicals (both natural and synthetic) in pregnant women in northern, central and southern Alberta (Phase 1), in children in southern Alberta (Phase 2), and maternal and umbilical cord blood samples from 7 Alberta cities (Phase 3). The goals of the program are to create a benchmark against which to track future exposures, provide a starting point for assessing health risks, indicate possible exposure sources and prioritize research efforts. Chemicals targeted for monitoring were selected using expert guidance and review of similar studies. For Phases 1 and 2, results for each chemical are presented in a single column, as either whole serum or lipid-adjusted concentrations. Each row provides the mean concentration and standard error of measurement for the replicate pools in the Age+Region group. Supplementary rows include the Limit of Detection/Limit of Quantification (LOD/LOQ) and Comments (for report status; results are only reported if ≥25% of pooled samples had detectable concentrations of a chemical). For Phase 3, results for each chemical are presented in up to 8 columns (age-weighted and age-and-geography-weighted means in whole serum and lipid-adjusted serum, and their 95% confidence intervals (CIs)). Each row provides the mean concentration and 95% CI for the replicate pools in the Age+Region group. Supplementary rows include the LOD/LOQ, Report Status (Yes: ≥25% of pooled samples had detectable concentrations; No: <25% had detectable concentrations) and Comments.
