International migration to Canada: the post-birth health of mothers and infants by immigration class.

There are over 214 million international migrants worldwide, half of whom are women, and all of them assigned by the receiving country to an immigration class. Immigration classes are associated with certain health risks and regulatory restrictions related to eligibility for health care. Prior to this study, reports of international migrant post-birth health had not been compared between immigration classes, with the exception of our earlier, smaller study in which we found asylum-seekers to be at greatest risk for health concerns. In order to determine whether refugee or asylum-seeking women or their infants experience a greater number or a different distribution of professionally-identified health concerns after birth than immigrant or Canadian-born women, we recruited 1127 migrant (and in Canada <5 years) women-infant pairs, defined by immigration class (refugee, asylum-seeker, immigrant, or Canadian-born). Between February 2006 and May 2009, we followed them from childbirth (in one of eleven birthing centres in Montreal or Toronto) to four months and found that at one week postpartum, asylum-seeking and immigrant women had greater rates of professionally-identified health concerns than Canadian-born women; and at four months, all three migrant groups had greater rates of professionally-identified concerns. Further, international migrants were at greater risk of not having these concerns addressed by the Canadian health care system. The current study supports our earlier findings and highlights the need for case-finding and services for international migrant women, particularly for psychosocial difficulties. Policy and program mechanisms to address migrants' needs would best be developed within the various immigration classes.

Cesarean section rate differences by migration indicators.

PURPOSE: To answer the question: are there differences in cesarean section rates among childbearing women in Canada according to selected migration indicators? METHODS: Secondary analyses of 3,500 low-risk women who had given birth between January 2003 and April 2004 in one of ten hospitals in the major Canadian migrant-receiving cities (Montreal, Toronto, Vancouver) were conducted. Women were categorized as non-refugee immigrant, asylum seeker, refugee, or Canadian-born and by source country world region. Stratified analyses were performed. RESULTS: Cesarean section rates differed by migration status for women from two source regions: South East and Central Asia (non-refugee immigrants 26.0 %, asylum seekers 28.6 %, refugees 56.7 %, p = 0.001) and Latin America (non-refugee immigrants 37.7 %, asylum seekers 25.6 %, refugees 10.5 %, p = 0.05). Of these, low-risk refugee women who had migrated to Canada from South East and Central Asia experienced excess cesarean sections, while refugees from Latin America experienced fewer, compared to Canadian-born (25.4 %, 95 % CI 23.8-27.3). Cesarean section rates of African women were consistently high (31-33 %) irrespective of their migration status but were not statistically different from Canadian-born women. Although it did not reach statistical significance, risk for cesarean sections also differed by time since migration (≤2 years 29.8 %, >2 years 47.2 %). CONCLUSION: Migration status, source region, and time since migration are informative migration indicators for cesarean section risk.

Refugee and refugee-claimant women and infants post-birth: migration histories as a predictor of Canadian health system response to needs.

BACKGROUND: Minority women from conflict-laden areas with limited host-country knowledge are among the most vulnerable migrants. Their risk status and that of their infants is magnified during pregnancy, birth, and post-birth. We conducted a study to determine whether women's postnatal health concerns were addressed by the Canadian health system differentially based on migration status (refugee, refugee-claimant, immigrant, and Canadian-born) or city of residence. METHODS: Women speaking any of 13 languages were recruited (with their infants) from postpartum units in the main Canadian receiving cities for newcomers (Toronto, Montreal, Vancouver; total n = 341 pairs from 10 hospitals) and followed at home after birth. Our primary interest was 'unaddressed concerns'; nurse-identified health concerns based on standards of postpartum care for the woman/infant at 7-10 days post-birth, for which no professional attention had been given or planned. RESULTS: A difference in unaddressed concerns by migration status was not found in our primary model [OR refugees vs. Canadian-born = 1.40 (95% CI: 0.67-2.93); refugee-claimants, 1.20 (0.61-2.34); immigrants, 1.02 (0.56-1.85)] although differences by city of residence remained after controlling for migration status, income, education, maternal region of birth, language ability, referral status, and type of birth [Toronto vs. Vancouver OR = 3.63 (95% CI: 2.00-6.57); Montreal, 1.88 (1.15-3.09)]. The odds of unaddressed concerns were greater in all migrant groups [OR refugees vs. Canadian-born = 2.42 (95% CI: 1.51-3.87); refugee-claimants, 1.64 (1.07-2.49); immigrants, 1.54 (1.00-2.36)] when analyses excluded variables which may be on the causal pathway. INTERPRETATION: Women and their newborn infants living in Toronto or Montreal may require additional support in having their health and social concerns addressed. The definitive effect of migrant group needs confirmation in larger studies.

The childbearing health and related service needs of newcomers (CHARSNN) study protocol.

BACKGROUND: Refugee and asylum-seeking women in Canada may have significant harmful childbearing health outcomes and unmet health and social care needs. The most vulnerable of these women are: those who have left their countries by force (e.g., war, rape or abuse histories), are separated from their families, have limited knowledge of the host country languages, and are visible minorities. Asylum-seekers face additional stresses related to their unknown future status and are marginalized with regards to access to provincial health care systems. The prevalence and severity of health issues in this population is not known nor is the extent of response from social service and health care systems (including variation in provincial service delivery). Understanding the magnitude of health and social concerns of newcomers requires data from a representative sample of childbearing refugee and asylum-seeking women resettling in Canada to permit comparisons to be made with non-refugee immigrant and Canadian-born women. Our research questions are: (1) Do refugee or asylum-seeking women and their infants, experience a greater number or a different distribution of harmful health events during pregnancy, at birth, and during the postpartum period than non-refugee immigrant or Canadian-born women? (2) Are the harmful health events experienced postpartum by asylum-seeking women and their infants, addressed less often (compared to refugees, non-refugee immigrants, and Canadian-born women) by the Canadian health care system as delivered in each of the three major receiving cities for newcomers? METHODS/DESIGN: This is a four-year multi-site prospective cohort study (pregnancy to 4 months postpartum). We will seek to recruit 2400 women [200 in each of 4 groups (refugees, asylum-seekers, non-refugee immigrants, and Canadian-born) from 1 of 12 postpartum hospital units across the 3 largest receiving cities for newcomers to Canada - Montreal, Toronto, and Vancouver]. DISCUSSION: Knowledge of the extent of harmful health events occurring to asylum-seeking, refugee, immigrant, and Canadian-born women, and the response of the health care system to those events and group differences, if they exist, will inform immigration and health policy makers as well as providers of services.
