What did you do for your PhD?

I looked at a range of factors affecting the health of refugee women and their babies. One was the path refugee women take to get to Canada, and the impact of that path on health.

What did you find?

Many refugees do not come straight to Canada from their country of origin. Instead, they spend time in another country first, often in a refugee camp or a similar precarious situation. I found that refugee women who spent time in another country before coming to Canada were more likely than other groups of refugees and immigrants to give birth before the baby was full term.

What did you learn from that?

Refugee women who live in another country before coming to Canada experience prolonged instability with poor living conditions, increased risk of personal violence, separation from or death of family members, and limited access to health care. The incredible stress of these conditions can cause babies to be born earlier than usual.

What can the health care system do to respond?

Health care providers can respond by understanding the migration experiences of women. Knowing whether a woman is a refugee, if she lived in another country prior to arriving In Canada and what the living conditions were like in that country, may be important indicators of stress. Health care providers should consider the stress refugee women have experienced and how this might be impacting their health and experiences of health care. Providers should also be aware of resources in the community such as counselling, cultural centres, settlement services, etc. in order to make appropriate referrals. Future research could consider developing best practices for health care providers who provide prenatal care for refugee women.

What are you doing at C-UHS?

I’m involved with two streams of research. Firstly, I am expanding my research into the health of refugee mothers and their babies. I am looking at additional factors that may cause poor health and a broader range of maternal and infant health outcomes. Some of these outcomes include high maternal blood pressure and admission to intensive care. Secondly, I am  leading a community-based qualitative research project to understand reproductive decision-making in the Indian immigrant community in the Greater Toronto Area with the goal of developing an educational brochure to reduce gender-bias.

In your ideal world, what would happen as a result of your research?

Greater interest and awareness among health care providers in terms of the unique experiences of refugee women and the potential for these experiences to impact health after immigration.

Why do you think research matters?

Research into the social determinants of health matters since it can help us understand who’s vulnerable to poor health and why. This research can help effectively target health care resources and upstream prevention strategies to improve population health and wellbeing.
