Purpose: Breastfeeding is the recommended feeding method by all leading health authorities due to the health promoting and disease preventative properties it provides to mothers and their infants. It is described that breastfeeding training in undergraduate medical education will help to improve knowledge and practice skills in physicians. Training medical apps have become an invaluable tool in the last 10 years. Its use could facilitate breastfeeding education in medical students. The purpose of this project was to compare the effectiveness of an App vs face-to-face lectures to promote breastfeeding education in medical students. Methods: The study was a controlled, prospective and nonrandomized clinical trial in which all senior students from the School of Medicine of the U.A.N.L. were included. They were divided into two groups. The control group with the face-to-face lectures and the intervention group with the use of an App. A pre-test of 20 multiple-choice questions was applied, specifically designed for this purpose. The control group received 4 face-to-face lectures with a total duration of 6 hours. The intervention group used an App for their smartphones called “Breastfeeding Education'' available in iOS and Android to which they had access during 2 weeks. The App consisted of 4 modules that covered the same topics as the face-to-face lectures. After this training, both groups had the same 20 questions-test applied. The results between both groups were compared. For the statistical analysis of the tests, the Wilcoxon and the Mann-Whitney U tests were used. Statistical analyses were done using SPSS version 20. Results: The total population was of 478 students (209 control group and 178 intervention group) (Figure 1). The mean time of use of the App was 2.2 hours per student compared to the total 6 hours of the face-to-face lectures. The number of correct answers increased significantly between the pre-test and post-test in both groups (p = <0.001) (Table 1). However, when comparing both methods, the control group had better results on the tests (median 4, range 3-6) than the intervention group (median 3, range 1-4) (p = <0.001). Conclusions: The mobile App was effective in helping medical students to learn about breastfeeding. However, the face-to-face lectures turned out to be more effective at evaluations. The time spent in the App was lower than in the face-to-face lectures. This result from the fact that the students only used the App during their free time and that they did not consider it as a mandatory requirement for their training. Nevertheless, the use of an App could help to reinforce breastfeeding education.
