0361 Sleep Disturbances in a Sample of Pregnant Military Mothers

Abstract

Abstract Introduction Pregnant civilians report poor sleep quality, insufficient nighttime sleep, sleep fragmentations, and significant daytime sleepiness. Sleep disturbances are associated with increased risk of adverse outcomes during pregnancy (e.g., pre-eclampsia) and labor and delivery outcomes (e.g., cesarean section). The military population is at increased risk of developing sleep disorders. The military population is at increased risk of developing sleep disorders. We aimed to identify the prevalence of insomnia symptoms in a sample of active duty and military dependent pregnant women. Methods Pregnant individuals (N=100) were recruited from large Military Treatment Facility in Texas. Participants were predominantly between ages 25-29 (32%), White (67%), Non-Hispanic (75%), in their second trimester (56%), Active Duty Air Force (48%), Enlisted (44%), and married (87%). In this cross-sectional study, participants completed a survey containing the Insomnia Severity Index (ISI), Pre/Peri pregnancy sleep, and obstetric care questions. Ordinal logistic regression was performed using SAS to determine if pregnancy trimester predicted outcomes including: insomnia, poor sleep quality, and perceived sleep-related impairment. Results Twenty percent presented with moderate/severe insomnia per ISI. The odds of having Insomnia (Severe vs No/absence) are 8.09x higher in the third trimester than first trimester (p=0.002). The odds of having poor sleep quality during pregnancy are 33.17x higher in the third trimester compared to first trimester (p<.0001). Mothers in the third trimester were 1.02x more likely to perceive other mothers as having significant sleep problems than those in the first trimester (p=0.02). Despite these reported sleep difficulties, 98% were not referred for a sleep consultation visit. Conclusion Findings suggested 20% of pregnant individuals associated with the U.S. Military experienced significant sleep concerns with no active plan for treatment. Individuals in their third trimester were more likely to have high ISI scores, report poorer sleep quality, and more likely to suspect significant sleep problems as common throughout pregnancy. Pregnancy is a critical period for intervention as chronic insomnia diminishes military readiness and compromises health. Insomnia prevention and intervention is greatly needed and could be integrated into obstetric clinics early in pregnancy.
