Seasonal variation in the frequency of anencephalus and spina bifida births in the United Kingdom.
نویسندگان
چکیده
There have been statistically significant seasonal variations of annencephalus and spina bifida in each country of the United Kingdom during 1964-79 with the exception of anencephalus births in Northern Ireland. The seasonal peaks, where discernible, are in phase. Embryos appear to develop anencephalus most commonly in May-June and spina bifida in July.

متن کاملSecular changes in the incidence of malformations of the central nervous system.
In a previous communication (Record and McKeown, 1949) it was noted that in Birmingham the incidence of anencephalus and spina bifida decreased during the years 1940-47, while the incidence of hydrocephalus remained fairly constant. It was tentatively suggested that this decrease might be correlated with changes in the parity distribution of births, since it was shown that the incidence of anen...
متن کاملContrasting effects of maternal fertility and birth rank on the occurrence of neural tube defects.
The relationships between the occurrence of anencephalus and spina bifida, sibship size and birth rank were examined, using linked records for births in British Columbia. Comparison of 414 sibships in which at least one infant had a neural tube defect with 1362 randomly chosen unaffected sibships showed that the affected sibships were larger. There were both more births than expected after the ...

The parents of 226 of the 360 patients with anencephalus or spinal bifida or both, born in Belfast 1964 to 1968, were visited to document the occurrence of these malformations among other relatives. The proportions of sibs with anencephalus and spina bifida were 10.41% for spina bifida index patients and 6.4% for anencephalus.

Cases were ascertained from national infant mortality and late fetal death records, and public hospital records and consisted of still and live births (of 28 or more weeks gestation) during 1978-1982 with anencephalus or spina...
