The Foresight Preconception Association in the U.K. carried out a study involving 367 couples who took part in a preconception health care program.
Among the participating couples, 217 (59%) had a previous history of reproductive problems:
- 136 were infertile
- 139 had a history of miscarriages
- 11 had a stillborn
- 40 were small-for-dates
- 15 were low birthweight
- 7 were malformed
- 3 infants died of sudden infant death syndrome.
After both partners completed the preconception care program, 327 couples conceived and had a healthy baby. All babies were born with an average birth weight of 3265 grams. Significantly, there were no miscarriages or malformations.
A 4-month preconception care plan can help prevent miscarriage, premature labour, stillbirths and birth defects and appears to have a success rate of over 80%.
