tions suffered stress as a result of the disaster and this is reflected in the later peaks in low birth weights.
She said it was difficult to explain why these later peaks occurred. It might be directly related to the disaster having occurred early in gestation, perhaps when the foetus was more susceptible to the effects of stress. Another hypothesis is that the Christmas and New Year holiday was a particularly emotional time after the disaster. The increase in very low birth weights (less than 1,500g) 33-36 weeks after September 11th suggests that exposure around the time of conception may also impact birth outcomes, although the exact mechanisms remain unknown.
Prof Eskenazi concluded: We have thoroughly reviewed the literature on preterm birth and low birth weight, and there is, thus far, a paucity of hard data to support the anecdotal information that women are more likely to have a spontaneous preterm birth immediately after a stressful event. Although we can't say for sure that our findings of increased births weighing less than 2,000g immediately after the events of September 11th are directly attributable to preterm delivery, we think that our results support this hypothesis and the paper supports the idea that stressful community events can impact the health of the foetus.
