Global initiatives to improve breastfeeding practices have focused on the Ten Steps to Successful Breastfeeding. The aim of this study was to assess the effect of implementing Baby-Friendly Hospital Initiative (BFHI) steps 1–9 and BFHI steps 1–10 on incidence of diarrhea and respiratory illnesses in the first 6 months of life.
We reanalyzed a cluster randomized trial in which health-care clinics in Kinshasa, Democratic Republic of Congo, were randomly assigned to standard care (control group), BFHI steps 1–9, or BFHI steps 1–10. Outcomes included episodes of diarrhea and respiratory illness. Piecewise Poisson regression with generalized estimation equations to account for clustering by clinic was used to estimate incidence rate ratios (IRR) and 95% confidence intervals (CI).
Steps 1–9 was associated with a decreased incidence of reported diarrhea (IRR 0.72, 95% CI 0.53, 0.99) and respiratory illness (IRR 0.48, 95% CI 0.37, 0.63), health facility visits due to diarrhea (IRR 0.60, 95% CI 0.42, 0.85) and respiratory illness (IRR 0.47, 95% CI 0.36, 0.63), and hospitalizations due to diarrhea (IRR 0.42, 95% CI 0.17, 1.06) and respiratory illness (IRR 0.33, 95% CI 0.11, 0.98). Addition of Step 10 attenuated this effect: episodes of reported diarrhea (IRR 1.24, 95% CI 0.93, 1.68) and respiratory illness (IRR 0.77, 95% CI 0.60, 0.99), health facility visits due to diarrhea (IRR 0.76, 95% CI 0.54, 1.08) and respiratory illness (IRR 0.75 95% CI 0.57, 0.97), and hospitalizations due to respiratory illness (IRR 0.48 95% CI 0.16, 1.40); but strengthened the effect against hospitalizations due to diarrhea (IRR 0.14, 95% CI 0.03, 0.60).
Implementation of steps 1–9 significantly reduced incidence of mild and severe episodes of diarrhea and respiratory infection in the first 6 months of life, addition of step 10 appeared to lessen this effect.
