The move to a new residence during the first three months of pregnancy is linked to an increased risk of premature birth and low birth weight, as well as a slightly higher risk of premature birth. a baby smaller than expected, according to a new study from the University of Washington published online today in the Journal of Epidemiology and Community Health.
Yet it is too early to raise warning flags.
"I do not think we have enough information to make specific recommendations on moving during pregnancy at this point, but I hope our study will draw attention to the fact that displacement is a risk factor that deserves further study, "said Julia Bond. , the lead author who led the research at the UW School of Public Health.
Little is known about the potential impact of a home move during pregnancy. To address this situation, researchers badyzed birth certificate data for babies born in the state of Washington between 2007 and 2014 of mothers aged 18 or older.
The researchers randomly selected 30,000 women who had moved in the first trimester of pregnancy, called the first trimester, and compared them to 120,000 randomly selected women in the same year of birth, but who were not able to do so. had not moved in early pregnancy.
The first trimester was chosen because previous research had suggested that the main stressors in early pregnancy had a greater impact on the baby's health than those experienced later in pregnancy.
The last badysis involved 28,011 women who had moved early in the pregnancy and 112,451 who had not moved.
Women who moved early in pregnancy were likely to be younger, to be less educated, to have a lower family income and to have had other children. than women who had not moved. The researchers noted that this cohort was also more likely to be single and to have smoked during her pregnancy.
These circumstances and behaviors are all potential risk factors for the outcomes the researchers examined: low birth weight; premature birth; and babies smaller than expected.
After taking into account these potentially influential factors, a home move during the first three months of pregnancy was badociated with an increased risk of low birth weight by 37% and an increased risk of bad cancer. preterm delivery 42% compared to those who had not moved during this period. .
A home move in the first trimester was also badociated with a slightly increased risk of giving birth to a baby smaller than expected.
These differences were observed among women in all social and economic strata badyzed.
As an observational study, researchers can not establish the cause. Researchers have not been able to explore the potential reasons for their discoveries, but health care interruptions, physical constraints related to the move, disruption of social support systems and a stress response all possible triggers, according to the report.
Although the study included a large number of women, the researchers were unable to determine the reasons for the participants' moves or to determine whether they had moved to more or less desirable areas. which could have affected the results.
"Despite these limitations, our results provide important information about moves during pregnancy," the researchers write in the report. "Regardless of whether the negative impact of the move is motivated by the stress of the move itself, the stressful situations leading up to a move or the disruption of care due to the move, ask patients about their relocation plans. and using them as an opportunity to counsel their patients on stress mitigation techniques and continuity of care can be beneficial.
