DESCRIPTION:Session: EH Poster Session 6: Household and Family Environment
 al Health Program : Environment Author: Nicole Deziel\, PhD Abstract Back
 ground About 5% of the U.S. population resides within 1.6 km of active oi
 l and gas development. Oil and gas development produces pollution includi
 ng reproductive toxicants and endocrine disruptors (e.g.\, particulate ma
 tter\, polycyclic aromatic hydrocarbons\, volatile organic compounds). De
 spite well-documented associations between residential proximity to oil a
 nd gas development and adverse birth outcomes\, no study has examined ges
 tational diabetes\, a condition with long-term consequences for maternal-
 infant health. Methods We examined associations between residential proxi
 mity to active oil and gas development during the preconception period an
 d gestational diabetes risk using data from Pregnancy Study Online (PREST
 O)\, an Internet-based cohort study of U.S. and Canadian residents. We us
 ed participants’ preconception residential addresses to calculate proximi
 ty to the nearest active oil or gas development site. Among participants 
 whose pregnancy progressed ≥28 weeks gestation\, we collected data on dia
 gnoses of gestational diabetes from self-administered questionnaires (com
 pleted in late pregnancy and postpartum) and birth records. We implemente
 d log-binomial regression to estimate risk ratios (RRs) and 95% confidenc
 e intervals (CIs)\, adjusting for age\, year\, and geographic region\, an
 d stratifying by pre-pregnancy body mass index (BMI). Results Among 6\,34
 0 pregnant participants (8.32% prevalence of gestational diabetes)\, prec
 onception residence within 5 km from active oil and gas development was p
 ositively associated with gestational diabetes (RR=1.28\, (95% CI: 1.00\,
  1.62)\, compared with ≥20 km from active oil and gas development. When s
 tratified by pre-pregnancy BMI ≤25 kg/m2 (n=3\,246)\, 25-29 kg/m2 (n=1\,5
 90)\, and ≥30 kg/m2 (n=1\,494)\, RRs for preconception residence <5 km (v
 s. ≥ 20 km) from oil and gas development were 1.02 (95% CI: 0.63\, 1.63)\
 , 1.22 (95% CI: 0.72\, 2.08) and 1.45 (95% CI: 1.06\, 1.98)\, respectivel
 y. Conclusion Preliminary results suggest that residential proximity to o
 il and gas development during the preconception period is modestly associ
 ated with gestational diabetes\, with some evidence that pre-pregnancy BM
 I modifies this association.\n\nAdmission:\nRegistrationFees: APHA Event
