Background:Infant and young child feeding is critical for child health and survival. Exclusive breastfeeding is the process of feeding a newborn baby exclusively with breast milk and no other supplement. It is recommended by WHO since it has several advantages for both child and mother. However, the prevalence of exclusive breastfeeding among infants younger than six months in developing countries remained low at 33% in 1995 and 39% in 2010. This study aimed to determine factors affecting exclusive breastfeeding using Theory of Planned and Behavior. Subjects and Method: This was a cross sectional study carried out at 25 Posyandus (integrated family health posts) in Gunung Anyar Puskesmas (Community Health Center), Surabaya, East Java, Indonesia, from April to May 2018. A sample of 200 was selected from 25 Posyandus of 2 strata. The dependent variable was exclusive breastfeeding. The independent variables were intention, attitude, subjective norm, knowledge, family support, and health personnel support. The data were collected by questionnaire and analyzed by a path analysis. Results:Exclusive breastfeeding was directly affected by intention (b= 2.59; 95% CI= 1.88 to 3.30; p< 0.001) and attitude (b= 1.19; 95% CI= 0.49 to 1.90; p= 0.001).
