Abstract: | The advantages of exclusive breastfeeding for the first 6 months are well‐known. Unfortunately, adolescent mothers have lower rates of breastfeeding exclusivity and shorter duration of breastfeeding. There is limited evidence regarding exclusive breastfeeding determinants in adolescent mothers. The purpose of this study was to obtain adolescent mother‐generated factors related to exclusive breastfeeding at 6 months. A mixed‐methods design was conducted through concept mapping. Thirty adolescent mothers aged 15–19 years who had wide range of exclusive breastfeeding experiences brainstormed about specific factors. They then sorted and rated the statements into key clusters. Finally, half of the participants were involved in the interpretation of the mapping results and the creation of pathway diagrams. Data were analysed by multivariate statistics in the Concept System Global MAX program. The results showed that the adolescent mothers brainstormed about 104 statements on the factors related to exclusive breastfeeding at 6 months. These factors can be categorized into the following six key clusters: (a) breastfeeding advantages; (b) facilitating factors and necessary skills; (c) promotion and support needed; (d) community and social influence; (e) internal and external barriers; and (f) key problems in families. The pattern matching provided understanding of how key clusters are important to successful breastfeeding through comparing three groups of exclusive breastfeeding durations. Finally, the relationships of the stated factors were drawn in pathway diagrams. Exclusive breastfeeding experiences among Thai adolescent mothers showed complexity involving multilevel influences of social systems. The promotion of optimal breastfeeding should recognize the influences of both personal and environmental factors. |
