Pregnant women are likely to find that the support of their partner will have the greatest influence on their mental health during pregnancy.
A recent study published in BioMed Central's open access journal BMC Public Health found that maternal emotional distress is most likely to be caused by the lack of support from a partner or spouse.
Since anxiety and depression during pregnancy can result in a premature birth of a low birth weight, international medical insurance customers might want to look into antenatal classes together to avoid these problems.
The research assessed 50,000 mums-to-be, looking at their health, relationship to alcohol and smoking and how they felt abut their work, family and partner.
From this information the team were able to discover that the amount of support a woman received from her partner had the strongest effect on her mental health.
Gun-Mette Rosand from the Norwegian Institute of Public Health commented: "Failure to recognise and treat emotional distress during pregnancy stores up problems for both mother and child, and impacts continuing family welfare.
"It is important that antenatal courses should include relationship classes and that close attention should be paid to women who lack the support of a good relationship."
