Abstract

Background: Housing insecurity has been shown to be associated with adverse infant birth outcomes, but these findings have been limited to young, low-income, predominantly Black and Hispanic populations. We examined the association of moving during pregnancy with infant birth weight and gestational age at delivery among a diverse sample of pregnant individuals.

Methods: Pregnant individuals (N=951) receiving Expect With Me group prenatal care in Nashville, TN and Detroit, MI completed surveys during second and third trimester of pregnancy. Participants were asked if they moved during pregnancy. Gestational age and birthweight were collected from patient health records. Multiple linear regression was used to examine the association between moving during pregnancy with infant birth outcomes, controlling for potential confounders. Multiple logistic regression was used to assess sociodemographic factors associated with having moved during pregnancy.

Results: Participants were 14-42 years old (mean 25; standard deviation 5.4). Sixty-four percent were Black, 23% White, and 13% other race. Seventy-three percent had public insurance. In adjusted analyses, individuals who moved during pregnancy delivered lower birth weight infants than those who did not move (B=-149.83, p=0.033). Factors associated with moving during pregnancy included being Black (versus White; AOR = 1.44), unemployed (versus employed; AOR = 1.52), a high school graduate/GED (versus at least some higher education; AOR = 0.72), and having private insurance (versus public; AOR = 1.36).

Conclusions: Moving during pregnancy is associated with lower infant birth weight. Several social determinants of moving during pregnancy were identified that warrant further exploration.
