Association between breastfeeding and complementary feeding in pre-pandemic and pandemic COVID-19 times: Maternar cohort study

Abstract

ObjectiveEvaluate the association between breastfeeding, exclusive breastfeeding at six months and the introduction of complementary feeding during the pre-pandemic and the COVID-19 pandemic periods. MethodsCohort study conducted with puerperal women and their newborns in the immediate postpartum period at a reference maternity hospital in Southern Brazil between 2018-2020. The COVID-19 pandemic period and the need to work outside the home during restricted circulation were the factors of exposure. The outcome evaluated was the weaning in the first six months (breastfeeding and exclusive breastfeeding) and the introduction of complementary feeding before the sixth month of life. Results547 puerperal women and their newborns were included. During the COVID-19 pandemic, there was a higher risk to weaning of exclusive breastfeeding up until six months (RR 1.16; 95%CI 1.03-1.31) and introducing complementary feeding early (RR 1.40; 95%CI 1.01-1.96). The need to work outside the home during the COVID-19 pandemic increased the risk of not breastfeeding exclusively at the sixth month (RR 1.27; 95%CI 1.08-1.49). ConclusionsThe difficulties of the pandemic did reflect negatively on breastfeeding and complementary feeding practices. The pandemic was a risk factor for the early weaning of exclusive breastfeeding and the introduction of complementary feeding. However, not having to work outside the home during the pandemic period was a protective factor for exclusive breastfeeding at six months.
