Objective

To analyze the factors associated with exclusive breastfeeding (EBF) in Peruvian women according to the ENDES-2019.

Methodology

This was an observational, retrospective, analytical, cross-sectional study that included a sample of 4 212 women aged 15 to 49 years who had a child under 6 months. In the inferential analysis, the association of factors was evaluated using the crude prevalence ratio (RPc). Additionally, the Poisson regression model with robust variance was used to calculate the adjusted prevalence ratio (RPa) along with their respective 95% confidence intervals, with a significance level set at p<0.05. The CSPLAN analysis was performed using SPSS for complex samples.

Results

The prevalence of SCI was 67.3%. In the bivariate analysis the associated factors were rural residence (RPc: 1.22; 95% CI: 1.17-1.27, p: 0.000), multiparity (RPc: 1.10; 95% CI: 1.05-1.16, p:0.000), vaginal delivery (RPc: 1.1; 95% CI: 1.03-1.16, p:0.003), teaching to prepare nipples for breastfeeding (BF) (PRc: 1.12; 95% CI: 1.051.19, p:0.000), teaching how to breastfeed your baby (PRc: 1.12; 95% CI:1.05-1.19, p:0.000) and BF training (PRc: 1.11; 95% CI:1.05-1.17, p:0.000). The factors significantly associated with EBF in mul-tivariate analysis were rural place of residence (PRa: 1.21; 95% CI: 1.15-1.27, p:0.000) and being multiparous (PRa: 1.12; 95% CI: 1.05-1.19, p:0.000).

Conclusions

The prevalence of EBF found in Peru was considered to be close to the millennium goal. The maternal profile significantly associated with EBF was rural residence and being multiparous.
