BACKGROUND According to a World Health Organization (WHO) review of nationally representative surveys from 1993 to 2005, 42% of pregnant women have anemia worldwide. Almost 90% of anemic women reside in Africa or Asia. Most countries have policies and programs for prenatal iron-folic acid supplementation, but coverage remains low and little emphasis is placed on this intervention within efforts...

The long-term benefits of antenatal iron supplementation in child survival are not known. In 1999-2001, 4,926 pregnant women in rural Nepal participated in a cluster-randomized, double-masked, controlled trial involving 4 alternative combinations of micronutrient supplements, each containing vitamin A. The authors examined the impact on birth weight and early infant mortality in comparison with...

Objective. To evaluate the rate of preterm birth and low birth weight in the newborns of pregnant women with early and late onset pre-eclampsia according to folic acid supplementation. Study design. Birth outcomes of newborns were evaluated in 1,017 (2.7%) pregnant women with medically recorded pre-eclampsia and 37,134 pregnant women without pre-eclampsia as reference in the Hungarian Case-Cont...

Periconceptional maternal folate levels may alter DNA methylation patterns and health outcomes in offspring. We hypothesized that maternal folic acid supplementation alters fetal neural development through DNA methylation in the fetal brain. Twenty-eight rats were randomly assigned to four groups: three groups of the female rats were fed folate-normal, folate-deficient or folate-supplemented di...

BACKGROUND A significant increase in the frequency of twins has been described in the literature as a secondary effect of perinatal supplementation with folic acid. AIM To verify if the frequency of twins increased in a Chilean hospital, after the start of flour folic acid supplementation. MATERIAL AND METHODS The frequency of twins was compared in the University of Chile Clinical Hospital,...

BACKGROUND With the goal of preventing open neural tube defects (NTDs), recommendations for folic acid supplementation before conception were introduced in Canada in 1994, and by November 1998 Canadian grain products were being fortified with folic acid. We wished to determine whether the annual incidence of open NTDs in Nova Scotia, including those in stillbirths and terminated pregnancies, ch...

OBJECTIVE To assess whether iron and folic acid supplementation reduce the risk of low birthweight (LBW) in women without anaemia. DESIGN Case-control study. SETTING University Hospital of Cantabria. STUDY POPULATION Cases were 322 mothers without anaemia delivering a singleton infant of less than 2500 g. Controls were 934 mothers without anaemia delivering a term non-small-for-gestationa...

BACKGROUND/OBJECTIVES Complications of diabetes, such as cardiovascular disease, are associated with increased mortality among type 2 diabetes mellitus patients. Homocysteine has been recently identified as a predictor of cardiovascular disease-related complications in diabetes. We investigated whether or not supplementation with folic acid tablets can lower homocysteine levels and improve para...

OBJECTIVE To investigate whether high doses of folic acid supplementation in early pregnancy are associated with child neurodevelopment at 18 months of age. DESIGN The study uses data from the prospective mother-child cohort 'Rhea' study. Pregnant women completed an interviewer-administered questionnaire on folic acid supplementation at 14-18 weeks of gestation. Neurodevelopment at 18 months ...

It has been conclusively established that folic acid supplementation prior to and during early pregnancy (up to 12 weeks of gestation) can prevent neural tube defects (NTDs). We hypothesized that folate effects may extend from neuro-structural defects to alterations in neuro-behavioural and emotional skills including autism spectrum disorders (ASDs) and other developmental disorders. The object...
