New York: Lifelong lower socioeconomic status of fathers, as defined by early life and adulthood neighbourhood income, is a newly identified risk factor for early preterm birth (at less than 34 weeks), said a new study.
According to the findings, published in Maternal and Child Health Journal, the rate of early preterm births was three times higher when fathers lived in lower income neighbourhoods, regardless of the mother’s age, marital status, education and race or ethnicity.
“We knew that the mother’s socioeconomic status is a risk factor for preterm birth, but this is the first time that the father’s status is linked to prematurity, even when the mother did not have high-risk demographics,” said study lead author James Collins, Professor at Northwestern University in the US.
“The father’s lifelong class status needs to be taken into account when designing initiatives to reduce the number of early preterm births among urban women,” Collins added.
For this study, the research team analysed the Illinois transgenerational birth file of infants (born 1989-1991) and their parents (born 1956-1976) with appended US census income data.
“Our results add to the mounting evidence suggesting that socioeconomic status is one of the most important drivers of worse pregnancy outcomes in the US, which has one of the highest rates of preterm birth among the developed countries,” Collins said.
“We need to address the social influencers of health for both parents in order to decrease preterm birth rates,” he added.
