Seasonal variation of neural tube defects in Newfoundland and elsewhere
Abstract In Newfoundland, babies with anencephaly are conceived most often in January, and those with spina bifida in August. These and previous observations suggest that (1) seasonal fluctuations are greatest when the population frequency is neither very high nor very low, and that (2) the peak sea...

| Summary: | Abstract In Newfoundland, babies with anencephaly are conceived most often in January, and those with spina bifida in August. These and previous observations suggest that (1) seasonal fluctuations are greatest when the population frequency is neither very high nor very low, and that (2) the peak season for conception of anencephalic babies may occur in any season except August‐November in various populations, whereas for spina bifida seasonal peaks are confined almost exclusively to May–August. |
