Extreme nausea and vomiting varies among pregnant women from different countries
Date:4/25/2008

dies we tested the quality of the data and therefore have confidence in our findings says Vikanes.

Mothers born in India and Sri Lanka had the highest prevalence of hyperemesis gravidarum, followed by those born in Africa (excluding North Africa) and Pakistan by 3.2 percent, 3.1 percent and 2.1 percent, respectively. Ethnic Norwegians, North Americans and Western Europeans had the lowest prevalence by 0.9 percent, 0.9 percent and 0.8 percent, respectively. A maternal age between 20-24 years old, being married, carrying a female foetus or more than one foetus were all socio-demographic characteristics associated with a higher prevalence of hyperemesis gravidarum.

Need to study further

The difference in prevalence of hyperemesis gravidarum related to the mothers country of birth cannot be explained by differences in socio-demographic characteristics, says Vikanes. We have to look for other explanations such as genetic factors, a change of diet or a history of infections. This topic needs further research to identify ways to prevent this life-threatening and distressing condition.
