Exclusive breastfeeding means feeding the infant exclusively with breast milk and without the intake of liquid and solid foods, except vitamins, minerals, and medicines. Continued exclusive breastfeeding can be achieved if the infant is only breastfed at least 6–8 times per day for the first 4–6 months after birth [1]. Breastfeeding is one of the most important ways to improve the health of infants in various communities. According to the UNICEF's findings, more than 3,000 infants die each day from infectious diseases due to bottle feeding, and 1.5 million infants die each year due to non-breastfeeding. In the late 1990s, mothers became more aware of the benefits of breastfeeding and they often chose to breastfeed their baby. But the impact of some factors has led to showing wrong breastfeeding behaviors, immediately stopping breastfeeding, and starting providing nutritional support to their infant, which gives rise to irreparable physical, psychological, and socio-economic harm to the infant and ultimately to society [2]. There is no doubt that breast milk is the best food for infants under six months of age. It is also a preventive agent in pediatric infectious diseases, allergies, adolescent diabetes, and obesity. In addition, it is beneficial to maternal health in terms of delay in fertility, protection against ovarian and breast cancer, and helping to restore pelvic organs to pre-pregnancy conditions. One of the goals of the World Health Organization (WHO) for feeding infants is to have at least 50% of infants exclusively breastfed by 2025 [3].
It is recommended that breastfeeding practices be strengthened and intensified in developing countries to relatively reduce infant mortality rates. However, only 42.6% of infants are exclusively breastfed during the first hours of birth and 9.54% during the first 6 months of life [4]. Although most mothers start breastfeeding immediately after delivery, unfortunately, this decreases during the first months after delivery. In addition to having positive effects on the mother and the infant, exclusive breastfeeding has also obvious effects on the family and community economy due to the non-consumption of powdered milk [5].
Studies show that the pattern of exclusive breastfeeding in the first 6 months of life varies in different parts of the world. In China, 80% of infants are exclusively breastfed for the first six months of life [6]. In the United States, 35% of mothers exclusively breastfed their infants up to the age of 6 months in 2000, but this figure reached 50% in 2010 [7]. According to the latest report of Multiple Indicator Demographic and Health Survey (IrMIDHS) in 2011, exclusive breastfeeding in the country was 53.13% (47.79% in the urban areas and 62.76% in the rural areas). The highest and lowest percentages of exclusive breastfeeding were also reported in Guilan (85/65) and Yazd (33/11), respectively. In Tehran province, 49.93% of infants were also exclusively breastfed up to 6 months [8]. In recent years, many efforts have been made to promote exclusive breastfeeding. Although in most cases, breastfeeding begins at birth, continued breastfeeding, particularly exclusive breastfeeding, is overlooked in some cases. Therefore, it is important to identify the factors affecting breastfeeding [2]. Breastfeeding behavior is influenced by various physiological and psychological factors in mothers. It should be noted that physiological factors are difficult to change and in some cases impossible, so the design of interventions should be based on psychological and motivational factors in order to promote the above-mentioned behavior [9].
Although breastfeeding education programs have been implemented for many years and its importance has been emphasized as well, different statistics on the duration of breastfeeding raise the question of what is the attitude of newly delivered mothers and what are the factors associated with their attitude [10].
Attitudes are determined by one's beliefs about the consequences of behavior and the outcomes of behavior (behavioral beliefs) that arise from the evaluation of the outcomes or consequences of those behaviors. Therefore, a person who has strong beliefs about the positive and valuable outcomes of performing a behavior will have a positive attitude toward the behavior. On the contrary, a person who has strong beliefs about the negative outcomes of behavior will have a negative attitude toward it. Attitudes are acquired through the relationship of one person’s world with another person, a physical body, a behavior, or a policy. Although many definitions of attitude have been proposed, most scholars agree that one's attitude examines his or her assessment of the subject [11]. Attitudes are measured both directly and indirectly. The indirect measurement prioritized when the goal is to design more accurate and appropriate interventions. Behavioral beliefs and evaluation of behavioral outcomes are two factors shaping attitudes that in indirect measurement, attitude is a result of the advantages of these two constructs. Behavioral beliefs are the belief that behavior is associated with (positive or negative) traits or specific outcomes. The evaluation of behavioral outcomes refers to the value dependent on a behavioral outcome or attribute [12]. The purpose of this study was, indirect measurement of the attitudes of primiparous mothers toward exclusive breastfeeding.
