The lack of support caused by the lock down associated with COVID-19 may have reduced the prevalence of breastfeeding. The objective of this work was to study the effect of the pandemic on socioeconomic status-adjusted breastfeeding rates.Method: retrospective observational cohort study in which the type of feeding of 389 babies was compared at 7 days, 2 months, 4 months and 6 months of life. The sample was divided into two groups according to the date of delivery: pre-pandemic (215 babies) and pandemic (174 babies). Sociodemographic variables, effectiveness variables such as the type of lactation at 1 week, 2 months, 4 months and 6 months, clinical variables related to childbirth and socioeconomic level were collected. Mixed-effects logistic regression models were used.Results: new-born during the pandemic had higher breastfeeding rates than before the pandemic. Breastfeeding rates are higher than the European average. We found statistically significant association of a greater probability of breastfeeding with the pandemic period and low and middle socio-economic status is striking.Conclusions: the protective effect of the pandemic could be related to mothers spending more time with their babies. Work entry is the main determinant of breastfeeding cessation. The policy of extending maternity leave would promote longer breastfeeding duration. Keywords: breastfeeding; postnatal care; social class; pandemics; coronavirus infections.
