Among women who got pregnant within six months, 85 percent had a healthy baby. Among women who waited more than two years to get pregnant again, the rate was 73 percent. The study was published Friday in the medical journal BMJ and was partly funded by the Chief Scientist's Office in Scotland, an agency of the Scottish government.
"It's unnecessary for women to wait to conceive again after a miscarriage," said Sophinee Bhattacharya, a lecturer in obstetric epidemiology at the University of Aberdeen in Scotland, one of the paper's authors.
She said current guidelines from the World Health Organization, which recommend women delay getting pregnant for at least six months after a miscarriage, should be changed. Bhattacharya said WHO guidelines are based on a study from Latin America, where women usually have children at an earlier age than in the West.
Because women in developed countries often wait until they are older to have children, Bhattacharya said any delays to conception could reduce the chances of a healthy baby.
