MONDAY, Dec. 4, 2006 (HealthDay News) -- Women who are underweight before they become pregnant are 72 percent more likely to suffer a miscarriage in the first three months of pregnancy, according to a study from the London School of Hygiene & Tropical Medicine.
The study of more than 6,600 women, aged 18-55, also found that underweight women can significantly reduce their risk of miscarriage in the first trimester by about 50 percent by taking supplements with folate or iron and by eating fresh fruits and vegetables every day.
Chocolate was also associated with reduced risk of miscarriage in this group of women.
The study is published in the current online edition of BJOG: An International Journal of Obstetrics and Gynecology.
Among the study's other findings:
"Our study confirms the findings of previous studies which suggest that following a healthy diet, reducing stress and looking after your emotional well-being may all play a role in helping women in early pregnancy, or planning a pregnancy, to reduce their risk of miscarriage," study author Noreen Maconochie, a senior lecturer in epidemiology and medical statistics, said in a prepared statement.
"The findings related to low pre-pregnancy weight, previous termination, stress and change of partner are noteworthy, and we suggest further work be initiated to confirm these findings in other study populations," Maconochie said.
