Based on a previous study, the constructs such as self-identity and moral norms can be added to the traditional TPB in order to include psychological variables that also contribute to the intention and behavior (). Therefore, we hypothesized that the extended model of TPB may provide more comprehensive information than the standard TPB to better predict the behavioral outcomes. Thus, the current study aimed to use the modified TPB framework to identify the factors determining the EBF, as well as the roles of socio-demographic factors in predicting the long-term breastfeeding behavior among Iranian mothers in a representative population. Methods This study was a longitudinal study in pregnant women who were followed up for six months after the child birth. Data were collected from September 2015 to March 2016 in Qazvin, Iran. There were 1445 women recruited during their third trimester of pregnancy. Maternal care is routinely delivered to all pregnant women by a health care referral system in Iran. There are fourteen health centers in Qazvin city, all of which provide maternal care in their affiliated areas. The clinical information of the pregnant women is normally kept by their health care centers. We invited the pregnant women in their last trimester and 91% of them accepted to participate. Their health records were obtained from the health centers. All participants provided consent forms. Women who were illiterate and with systemic diseases and breast abnormalities were excluded from the study. Several questionnaires (described below) were used to collect the data and the participants were asked to complete the questionnaires
