Objective:

to evaluate the impact of the economic crisis on the disparities in the prevalence and risk of low birth weight (LBW) according to the maternal socioeconomic profile.

Methods:

the data analysed corresponds to 1,779,506 single births to Spanish mothers in the years 2007, 2009, 2011, 2013 and 2015. The temporal changes in available maternal-foetal variables are described. Secondly, the possible increase in disparities in prevalence and risk of LBW due to the occupation and education of the mother is evaluated, taking 2007 as the reference year.

Results:

a trend of the maternal profile is described among women who had children during this period, with an increasing contribution of highly qualified professional and educated women, a trend already existing before the economic crisis, but which was deepened by the recession. The prevalence of LBW increased in all socio-economic groups, with a marked increase in disparities during the worst years of the economic crisis.

Conclusion:

results confirm the persistence of social inequalities in perinatal health described prior to the economic crisis, as well as a possibly negative effect of the recession between 2007 and 2015. Results also confirm that disparities in LBW are more clearly associated with the educational level of mothers than with their occupation.
