Introduction: breastfeeding is a priority objective in public health. Health care professionals involved in the delivery of hospital-based maternal and child health services need to have adequate knowledge of breastfeeding.

Material and methods: we conducted a cross-sectional descriptive study in January and February 2015 using the validated questionnaire ECola, which we adapted for administration to gynaecologists, midwives and nurses. To survey nursing assistant technicians (NATs), we adapted the questionnaire developed by Temboury Molina MC, modified by the authors. The study universe consisted of all health care professionals involved in the delivery of maternal and child health services in the 14 public hospitals of Castilla y León.

Results: we received a total of 724 questionnaires (61.0%). Having defined a threshold of 70% of correct answers (16.8 points) to define adequate knowledge, nurses had an adequate knowledge of breastfeeding (18.19) that was significantly better (p < 0.05) compared to physicians (17.01). Midwives had the highest mean score (20.03). Gynaecologists, with a mean score of 15.24 points, had a level of knowledge considered inadequate. Nurse assistants, with a mean score of 16.93 points, exhibited adequate knowledge but close to the lower limit. We found statistically significant differences in knowledge between the providers working in different hospitals. Overall, the level of knowledge of professionals working in maternal and child health in public hospitals in Castilla y Leon was adequate (17.54).

Conclusions: overall, the level of knowledge of  health professionals involved in delivery of maternal and child health services was adequate. Some categories of professionals lacked knowledge in aspects that are essential to the adequate management of breastfeeding. We need to consider the need to include training in breastfeeding in educational curricula, especially those of gynaecologists and NATs.


Breastfeeding Knowledge Midwives Nurse assistant technicians Nursing Physicians


The Global Strategy on Infant and Young Child Feeding (GSIYCF) was developed by the World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF), approved by the Board in 2002. It reinforced the importance of promoting and supporting exclusive breastfeeding in the first 6 months of life and maintenance of breastfeeding combined with a feasible diet of adequate, safe and appropriate complementary foods through age 2 years.1

Multiple studies conducted in Spain2-5 and other countries6-9 have described the factors associated with the prevalence of breastfeeding, and all of them have emphasised the important role of the health professionals that are in contact with the mother, both during pregnancy and after birth.

The first and possibly most important step to promote breastfeeding is to improve the knowledge and attitudes of health care providers. They must be able to help mothers initiate breastfeeding and address the questions and concerns that arise during breastfeeding.10 The education of parents before and after birth seems to be another essential factor for successful breastfeeding.11

Every instance in which breastfeeding is dropped due to lack of training of health professionals constitutes a failure of the health care system. To date, there were no validated tools for the assessment of knowledge about breastfeeding in Spain. The rigorous work of Gómez Fernández-Vegue and Menéndez Orenga has produced a valuable instrument that allows us to evaluate knowledge and skills in breastfeeding.12 A questionnaire was developed in the context of the Baby Friendly Hospital Initiative (BFHI) to assess the knowledge and training needs of health care professionals on the subject of breastfeeding13 and disseminated in mid-2015, but we do not have any current data on its use in Spanish hospitals.

The current situation of breastfeeding in Castilla y Leon is that 82.7% of mothers initiate exclusive breastfeeding, but only 27.1% (95% confidence interval [95 CI]: 21.8 to 39.9) maintain it through 6 months post birth.14 There are no published data for Castilla y Leon about the knowledge of health professionals regarding breastfeeding.


Study design: we conducted a descriptive cross-sectional study in January and February 2015.

Study universe: health care professionals of any type (paediatricians, gynaecologists, midwives, nurses, nurse assistant technicians [NATs]) involved in the delivery of maternal and child health services in the 14 hospitals of the Regional Public Health Administration of the Autonomous Community of Castilla y Leon (SACYL): 1187 health care providers. We chose to survey the entire population to obtain data from every hospital.

Methods: we used two questionnaires as measurement tools:

Questionnaire 1: questionnaire on the Knowledge of Breastfeeding (Encuesta sobre Conocimientos en Lactancia Materna, ECola),12 validated for use in paediatricians and medical intern-residents (MIR) in the area of paediatrics. In collaboration with the authors of the original questionnaire, we adapted it to make it applicable to gynaecologists, midwives and nursing staff. We obtained the permission of the authors to do so, and the final version used in the study included 42 items.

Items 1 to 8 collect data about the health provider. The questionnaire has been validated, and it includes 24 items whose answers can be rated (items 9 to 33 excluding item 30, which we could not rate, as it was an open-ended question). We gave correct answers 1 point. A total score of 24 points thus corresponded to 100% correct answers. The questionnaire also included items whose answers could not be scored (items 34 to 42), which addressed the attitudes of health professionals toward breastfeeding, which we did not analyse in this study.

The questionnaire explored basic knowledge and skills in breastfeeding: physiology of breastfeeding, public health, problems in the first few days, late problems, assessment of intake during feeds, maternal factors and attitudes.

Questionnaire 2: this questionnaire was developed by Temboury Molina in 200310 to assess the knowledge of paediatrics MIRs in Spain on the management of breastfeeding. Since it is simple and it explores the knowledge areas that we considered important, we used it to survey NATs after making minor adjustments. The final questionnaire comprised 29 items. Items 1 to 4 explored sociodemographic characteristics. Items 5 to 28 received a score of 1 point if answered correctly. We did not score item 29 because it was an open-ended question.

We assessed basic knowledge areas about breastfeeding: advantages of breastfeeding, risks of artificial feeding, mechanisms of lactation and sucking, skills to adequately manage breastfeeding initiation and maintenance, assessment of feeds, management of difficulties, and hospital regulations regarding breastfeeding.

Study protocol: we reached out to health professionals through a letter sent from the Directorate General of Public Health to the administrators, medical directors, directors of nursing and supervisors of maternal and child health services in all hospitals of Castilla y Leon. We also contacted the Asociación Castellanoleonesa de Matronas (Midwife Association of Castilla y Leon, ASCALEMA) to appoint a study coordinator in each hospital. Questionnaires were administered in paper form and completed during team meetings or patient care conferences, at which point respondents also signed their informed consent to participation.

We performed the analysis using the software package IBM SPSS Statistics version


Sociodemographic data

The distribution of respondents to questionnaire 1 by professional category was: 13.3% neonatologists, 18.6% gynaecologists, 24.8% midwives, 19.7% nurses employed in the maternity ward, 19.5% nurses in the neonatal ward. Most respondents were female (87.1%), and the median age was 43.6 years (±10.6), 62.5% had children and 59.2% had experience breastfeeding.

In questionnaire 2, the distribution of respondents that were NATs was predominantly female (95.8%), with a mean age of 53.1 years (±7.5), 78.8% had children, most of them 2 children (61.1%).

Some respondents did not complete some of the questions in the sociodemographic section (Table 1).

Response rate

We received a total of 724 responses (corresponding to 61.0% of all eligible health providers in Castilla y Leon). Questionnaire 1 was completed by 512 professionals (response rate of 60.5%) and questionnaire 2 by 212 (response rate of 62.2%) (Table 2).

We found statistically significant differences based on sex and age; physicians that responded were younger, and there was a predominance of the female sex.

We did not find statistically significant differences in participation based on type of employment, personal experience with breastfeeding, or years of professional experience.

Variation in participation in the different public hospitals of Castilla y Leon

We found significant differences (p < 0.05) between hospitals in the response rate. In most hospitals (9/14), between 50% and 70% of the health care staff in women’s and children’s services participated in the survey (Figure 1).

Level of knowledge by professional category

To analyse the level of knowledge, we set a minimum of 70% of correct answers (16.8 points) to define adequate knowledge. We based this threshold on the recommendations of the authors of the questionnaires,12 who categorised scores as: <50% very poor, 50%-70% inadequate, 70%-85% adequate, > 85% excellent. A study in Canada also set a threshold of 70% to define adequate knowlege.18 Neonatologists, midwives, nursing professionals in the maternity ward and NATs exhibited adequate knowledge. Gynaecologists did not achieve the recommended minimum number of correct answers (Tables 5 and 6, Figure 2).

Given that we conducted a survey of breastfeeding knowledge addressed to all professionals employed in maternal and child health services in public hospitals of the SACYL based on the information of the database of this public health system, obtained a high response rate (60.9%), and the administered the survey in paper form and within the framework of clinical team meetings, we expect that our findings provide an accurate perspective regarding the knowledge of health providers on this subject.

In our review of the literature, we did not find a similar study conducted in Spain in the previous literature surveying different types of professionals or the entire collective of professionals involved in maternal and child care in all the public hospitals of an autonomous region. We did find studies involving specific types of professionals (resident physicians in paediatrics,10 paediatricians and residents in paediatrics,12 family physicians in Tenerife15 and various health providers in a single health district in the Valencian Community,16 but found no studies comparing the different categories of health professionals.

In the state of Sonora (Mexico),17 which has a very different health care system compared to ours, a similar study was conducted using an adaptation of the questionnaire developed by Temboury that also included residents in paediatrics and gynaecology.10 The questionnaire was administered by students of nutrition with random selection of a sample of physicians and nurses (327 responses). This study also concluded that the knowledge of breastfeeding of health professionals was inadequate, although the authors found that residents in paediatrics achieved better scores, which could be explained by previous training in educational workshops and conferences.

The study conducted in Canada to assess the knowledge, beliefs and attitudes of paediatricians, family physicians and final-year residents in paediatrics and family medicine18 found a score below 70% (the threshold for correct knowledge) in physicians, while the score of residents in paediatrics exceeded 70%.

To improve breastfeeding outcomes and offer solutions to the problems reported by mothers, it is important to evaluate the baseline level of knowledge. In pursuit of the same objectives and after we had started our study, the BFHI in Spain in 2015 published a document “Monitorización de la formación en atención a la lactancia materna mediante encuestas a profesionales” (Monitoring of training in the management of breastfeeding by surveying health professionals)13 proposing a tool for monitoring levels of training and educational needs and recommending a yearly survey of health professionals and the sample sizes to be obtained in different hospitals based on the number of beds. This proposal of the BFHI has not yet led to published results.

Our findings have highlighted different aspects for consideration. More than 80% of midwives and neonatologists had an “adequate” level of knowledge, but only 39% of gynaecologists reached this threshold, and no more than 40% of professionals in the remaining categories reached it either. Therefore, in two-thirds of the professional categories that are in contact with mothers that initiate breastfeeding, a substantial proportion of providers do not have knowledge at a level considered “adequate” in our study.

Our study revealed a lack of training in breastfeeding protocols and skills in the inpatient setting in NATs, who are professionals that carry out important tasks in this area. They were not aware of the significant impact of the introduction of bottles (items 8 and 19), challenges breastfeeding and the use of pacifiers (item 21), the importance of early skin-to-skin contact and the first feed (item 23) and did not recognised as erroneous something as basic as the need to wash the breasts before and after breastfeeding (item 25, 44.8%). Nearly half of these providers failed to reach the threshold for a level of knowledge defined as adequate.

Overall, our findings call for a reflection on the need to invest in training in breastfeeding across all involved categories of health professionals, especially gynaecologists, whose close involvement in the management of mothers at the time of breastfeeding initiation is of utmost importance. The level of knowledge in this collective of professionals was lowest of all.

Based on the answers to items 19, 21, 23, and 25 in questionnaire 1, we could state that despite the campaigns that have been implemented, the importance of exclusive breastfeeding through age 6 months and maintenance of breastfeeding combined with complementary foods through age 2 continues to be underestimated. There also seems to be a lack of awareness of the need to support mothers in addressing any challenges that may arise during this period.

Our findings confirm the frequent ignorance of the code on the marketing of breast milk substitutes and the tools that could help integrate breastfeeding in everyday clinical practice, such as the website and other digital applications, both of which have a direct impact on the prevalence of breastfeeding.

All professionals involved in maternal and child health services in hospitals in Castilla y Leon recognised their lack of specific training in breastfeeding, and nearly 90% considered this training important to be able to diagnose and successfully manage specific problems in breastfeeding, which they considered areas within the scope of their profession (item 39).

When we reviewed the official educational curricula for the degree in Medicine of the Universidad de Valladolid19,20 and for different medical specialties, we found that medicine students are only educated on the physiology of lactation and that the educational curriculum for the MIR residency in gynaecology did not include specific training on the physiology of lactation, although it did specify the need to train residents on breastfeeding-related problems in the postpartum period.21 The published official educational curriculum for NATs does not include any contents related to breastfeeding.22

The learning objectives of the official educational curricula published for paediatricians,23 nursing professionals,24-27 midwives28 and paediatric nurses29 include training in breastfeeding, although with a varying depth. Our findings show that there is a clear correlation between knowledge and the previous training of professionals, and highlight the need to improve the knowledge, skills and competencies in different types of health providers. There ought to be an emphasis on offering specific training in breastfeeding to those professionals that do not receive any during their formal education, such as gynaecologists and NATs.

Based on our findings, the knowledge of breastfeeding of the health care staff providing women’s and children’s services in Castilla y Leon in 2015 was lacking in aspects that are essential for the adequate management of breastfeeding: health providers lacked basic knowledge and skills with an impact on breastfeeding, made recommendations that did not promote breastfeeding (delaying the first feed, fixed feeding schedules, use of bottles and pacifiers), and when difficulties arose simply recommended discontinuation of breastfeeding, disregarding the wishes of the mother and the wellbeing of the infant. Having defined a score of 16.8 points (70% correct answers) as the threshold for adequate “knowledge”, we found that neonatologists, midwives and nurses and NATs employed in maternity or neonatal wards reached this threshold, while gynaecologists exhibited “inadequate” knowledge.

Breastfeeding is not a subject relevant solely to nursing professionals or those who have “an interest in the subject”, on the contrary, due to its importance for the promotion of public health, it is the duty of politicians and health care administrators to develop adequate educational strategies for inclusion in the curricula of the different health professions and joint training programmes for delivery in the maternal and child health units of all hospitals addressed to all the professionals involved in the care of women and infants (neonatologists, gynaecologists, midwives, nurses and NATs). In short, improving the prevalence of breastfeeding in the autonomous region of Castilla y Leon will require an investment on specific training in breastfeeding.
