What predicts the knowledge of breastfeeding practices among late adolescent girls? evidence from a cross-sectional analysis

INTRODUCTION: Breastfeeding is one of the most effective ways to ensure infant health and survival. Inadequate breastfeeding practices, and knowledge among adolescent mothers have led to unprecedented infant and child morbidity and mortality. Given, the high global prevalence of adolescent mothers it is imperative to understand how the knowledge of breastfeeding practices operates among adolescent girls across different socio-economic settings. MATERIALS & METHODS: Data was carried out from Understanding the Lives of Adolescents and Young Adults (UDAYA) survey, conducted in 2015–16. Descriptive statistics along with bivariate analysis was done to examine the preliminary results. For analysing the association between the binary outcome variable and other explanatory variables, binary logistic regression method was used. The explanatory variables were educational status of the respondent, media exposure, working status, ever pregnant status (only for married adolescent girls), sex and age of the household head, educational status of the head of the household, caste, religion, wealth index, residence and states. RESULTS: About 42%, 50%, and 42% of married adolescent girls had knowledge of immediate breastfeeding, yellowish milk, and exclusive breastfeeding respectively. The odds of knowledge about immediate breastfeeding [married-AOR: 1.57; CI: 1.09–2.28 and unmarried-AOR: 1.30; CI: 1.08–1.55], yellowish milk feeding [married-AOR: 2.09; CI: 1.46–3.01 and unmarried-AOR: 1.39; CI: 1.17–1.66], and exclusive breastfeeding [married-AOR: 1.74; CI: 1.2–2.52 and unmarried-AOR: 1.46; CI: 1.22–1.76] were significantly more among adolescent girls aged 19 years old compared to 15 years old girls. Adolescent married and unmarried girls with 10 & above years of schooling were 1.82 times [AOR: 1.82; CI: 1.52–2.18] and 2.69 times [AOR: 2.69; CI: 2.08–3.47] more likely to have knowledge about immediate breastfeeding, 1.74 times [AOR: 1.74; CI: 1.45–2.09] and 2.10 times [AOR: 2.10; CI: 1.68–2.62] more likely to have knowledge about yellowish milk feeding, and 3.13 times [AOR: 3.13; CI: 2.6–3.78] and 3.87 times [AOR: 3.87; CI: 2.95–5.08] more likely to have knowledge about exclusive breastfeeding respectively than girls with no schooling. CONCLUSION: Breastfeeding practices and interpersonal counselling from elders in the household should be encouraged. Ongoing breastfeeding promotion programs of the government should promote high education of adolescent girls. Mass media interventions should be encouraged.
