“…A study of Hurricane Katrina suggested some effects lingered 5-7 years later, 48 while 1 study of county-level PTB rates after disasters found effects lasting only for 2 to 3 weeks after the hurricane exposure. 46 As many of the effects of disaster exposure-stress, economic problems, lack of access to health care-linger for months or years, it is reasonable that exposure to post-disaster life early in pregnancy would have similar effects. Also consistent with previous studies is the lack of effect on PTB in the most-exposed counties, 7,12-28 especially confusing as there was an increase in the moderately exposed counties.…”

Objective: The aim of this study was to examine birth outcomes in areas affected by Hurricane Michael. Methods: Vital statistics data of 2017–2019 were obtained from the state of Florida. Births occurring in the year before and after the date of Hurricane Michael (October 7, 2018) were used. Florida counties were divided into 3 categories reflecting extent of impact from Hurricane Michael. Birth outcomes including incidence of preterm birth (PTB), low birth weight (LBW), and small for gestational age (SGA) were also compared before and after Hurricane Michael. Spontaneous and indicated PTBs were distinguished based on previously published algorithms. Multiple regression was used to control for potential confounders. Results: Both LBW (aRR 1.19, 95% CI: 1.07, 1.32) and SGA (aRR 1.11, 95% CI: 1.01, 1.21) were higher in the year after Michael than the year before in the most-affected area; a similar effect was not seen in other areas. A stronger effect was seen for exposure in the first trimester or in the 2 months after Michael than in the second or third trimester. Conclusion: Consistent with many previous studies, this study of Hurricane Michael found an effect on fetal growth.

Numerous studies have shown associations between maternal stress and poor birth outcomes, but evidence is unclear for causal inference. Natural disasters provide an opportunity to study effects of quasi-randomized hardship with an accurate measure of onset and duration. In a population-based quasi-experimental study, we examined the effect of maternal exposure to the January 1998 Québec ice storm on birth outcomes by comparing pregnant mothers who lived in an area hard hit by the ice storm with those in two unaffected regions. In a total of 147,349 singleton births between 1995 and 2001, we used a difference-in-differences method to estimate the effects of the ice storm on gestational age at delivery (GA), preterm birth (PTB), weight-for-gestational-age z-scores (BWZ), large for gestational age (LGA), and small for gestational age (SGA). After adjusting for maternal and sociodemographic characteristics, there were no differences between the exposed and the unexposed mothers for birth outcomes. The estimated differences (exposed vs. unexposed) were 0.01 SDs (95% CI: −0.02, 0.05) for BWZ; 0.10% point (95% CI: −0.95%, 1.16%) for SGA; 0.25% point (95% CI: −0.78%, 1.28%) for LGA; −0.01 week (95% CI: −0.07, 0.05) for GA; and 0.16% point (95% CI: −0.66%, 0.97%) for PTB. Neither trimester-specific nor dose–response associations were observed. Overall, exposure to the 1998 Québec ice storm as a proxy for acute maternal stress in pregnancy was not associated with poor birth outcomes. Our results suggest that acute maternal hardship may not have a substantial effect on adverse birth outcomes.

“…The county level is also where decisions and policies around disaster preparation and response are often undertaken. As part of a separate research team, Anderson used the opensource package to assess whether tropical cyclone exposures are linked to adverse birth outcomes 5 and is currently studying hospitalization risk among the elderly. Kioumourtzoglou is using the data set to study whether health outcomes such as hospitalizations for asthma attacks, heart attacks, or infections go up or down with exposure to tropical cyclone hazards.…”
