Couples who immigrate to Canada face lower risks of having a preterm birth than Canadian-born couples, according to a research recently published in the Journal of Obstetrics and Gynaecology Canada. The findings are consistent with the so-called “healthy immigrant effect”, which states that people who emigrate are healthier than those who remain in their country of origin and those from the country they immigrate to.
According to the study, the rate of preterm birth in the case of immigrant couples in Canada was three percent lower than the preterm birth level in their home country. The report also found that the healthy immigrant effect functions differently among foreign communities. In Ontario, for instance, the researchers discovered that the risk of preterm birth was higher among couples who came from Congo, Ghana, the Philippines, Jamaica, and Trinidad and Tobago. Specialists say that this is a result of the fact that women from these countries have higher blood pressure.
The study was based on more than 1.2 million births among parents from 184 countries, from 2002 to 2011.
