Marta Carvalho, Armanda Rebelo, João Filipe Nico, Filipa Inês Cunha, Catarina Oliveira Pereira Hospital Distrital Da Figueira Da Foz, Otra, Portugal INTRODUCCIÓN Y OBJETIVOS Some studies report an association between breastfee- ding or feeding to sleep (regardless of being with breast milk or formula) and altered sleep pattern, but without con- sistent results. The goal of this study was to evaluate if breastfed (BF) and fed to sleep (FTS) children have worse sleep patterns and if so, if any of these factors has a pre- ponderant role. MÉTODOS Analytical observational study using an online question- naire answered by mothers of children from 1 to 3 years old. Comparison of sleep pattern between BF and non-breast- fed (NBF) children and between FTS and non-FTS (NFTS) children. A significant value of <0.05 was considered statis- tically different. RESULTADOS The authors obtained 487 answers. The median age was 2 years old [1.3;2.8], 53% were female. There were 37% BF children and 30% FTS children. Sleep latency above 30 minutes (prolonged sleep laten- cy, PSL) was more common in NBF and in NFTS children, both without statistically significant difference. Co-sleeping and frequent (≥3) awakenings per night (APN) were more commonly reported in BF and in FTS children, all with statis- tically significant difference. Sleep duration was shorter in BF children, without statistically significant difference, and in FTS children, with statistically significant difference. Significant overlap was identified between BF and FTS groups. In the BF group, 65% were FTS and in the FTS group, 82%were BF. Because of this, subgroup analysis was performed. Analysing only FTS children, the only statistically signifi- cant difference was found for co-sleeping, more frequent in BF children. Considering only BF children, statistically significant di- fferences were identified in co-sleeping and having fre- quent APN, both more common in FTS children, and in sleep duration, shorter in FTS children. CONCLUSIONES Both BF and FTS children had increased frequent APN, more co-sleeping and reduced sleep time, although less fre- quent PSL. In subgroup analysis, when considering FTS chil- dren, only co-sleeping frequency was statistically signifi- cantly increased by breastfeeding. However, in BF children, three factors were statistically significantly modified by feeding to sleep: more co-sleeping, more frequent APN and shorter sleep duration. Due to the benefits of breastfeeding and these results suggesting that the timing of feeding has higher interfe- rence in sleep quality than the type of feeding, the authors recommend avoiding feeding to sleep as a routine.
