BACKGROUND Recognized risk factors for neural tube defects (NTDs) poorly predict
population‐level NTD risk. However, the proportion of NTDs that can be attributed to these …

BACKGROUND: Neural tube defects (NTDs), including spina bifida and anencephaly, are
the second most common birth defect with an incidence of 1/1000. Genetic factors are …

The epidemiological investigation of the common open neural tube defects (NTDs),
anencephaly, and spina bifida, has a long history. The most significant finding from these …

Purpose To explore the risk factors for neural tube defects (NTD) in Shenyang, we carried
out a population-based case-control study. Methods We used chi-square test or Fisher's …

Objectives. To conduct surveillance for neural tube defects (NTDs) in a high-risk region of
the United States and to prevent occurrence and recurrence of NTDs through the …

Background: Prenatal screening and the promotion of folic acid intake could affect the
incidence of neural tube defects (NTDs). We examined trends in the total NTD incidence, as …

The worldwide incidence of neural tube defects (NTDs) ranges from 1.0 to 10.0 per 1,000
births with almost equal frequencies between two major categories: anencephaly and spina …

Background We sought to assess the recent trend in NTD prevalence at birth in the post‐
folic acid food fortification era and to identify the maternal risk factors associated with that …

Abstract Objective Neural tube defects [NTDs] are severe congenital anomalies. The
etiology of NTDs is not fully known, and studies on the potential risk factors of NTDs present …
