Investigation of factors associated with delayed initiation of breastfeeding in Papua New Guinea: a cross-sectional study.

Background: Breastfeeding within the first hour of birth is critical for newborn survival. However, in Papua New Guinea (PNG), about 40% of newborns are not breastfed within the first hour of birth. This study aimed to determine the prevalence and factors associated with delayed initiation of breastfeeding in PNG.

Methods: This study used secondary data from the 2016-2018 PNG Demographic and Health Survey, a nationally representative cross-sectional study. A total weighted sample of 4748 women aged 15-49 were included. Complex samples analysis was performed to determine the direction of association between the independent variables and delayed initiation of breastfeeding.

Results: About a quarter (24.6%) of women delayed initiation of breastfeeding. Women with an unplanned pregnancy (adjusted OR (AOR) 1.32; 95% CI 1.03 to 1.68), those who had a caesarean section (AOR 3.16; 95% CI 1.39 to 7.17), those who did not initiate newborn skin-to-skin contact immediately after birth (AOR 1.83; 95% CI 1.41 to 2.38) and those who watched television (AOR 1.39; 95% CI 1.11 to 1.75), and were from the Momase region (AOR 1.31; 95% CI 1.00 to 1.93) had higher odds of delayed breastfeeding initiation. Conversely, the odds of delayed initiation of breastfeeding was lower among women who read a newspaper or magazine (AOR 0.76; 95% CI 0.61 to 0.95), were from the Southern (AOR 0.81; 95% CI 0.56 to 1.15) and Highlands (AOR 0.86; 95% CI 0.58 to 1.29) regions, and gave birth at home or in the village (AOR 0.69; 95% CI 0.49 to 0.96).

Conclusion: One in four women in this study delayed initiation of breastfeeding until after 1 hour after birth. Interventions to promote optimal breastfeeding require a multi-sectoral approach, as well as bolstering health workers' capacity to encourage and support early initiation of breastfeeding during the antenatal and early postnatal periods.
