BACKGROUND: EVERY ENCOUNTER A HEALTHCARE PROFESSIONAL HAS WITH NEW OR EXPECTING PARENTS OFFERS AN OPPORTUNITY FOR ADDRESSING IMPROVED EARLY NUTRITION AND LIFESTYLE. EVIDENCE-BASED QUALIFICATION PROGRAMMES VIA E-LEARNING OFFER VALUABLE TOOLS FOR ATTENUATING THE WORLD'S HUGE DOUBLE BURDEN OF BOTH UNDER- AND OVERNUTRITION IN EARLY CHILDHOOD. WE EVALUATED USE AND LEARNER SATISFACTION OF A GLOBAL E-LEARNING PROGRAMME ON EARLY NUTRITION AND LIFESTYLE ADDRESSING INTERNATIONAL HEALTHCARE PROFESSIONALS. METHODS: WE IMPLEMENTED THE EARLY NUTRITION SPECIALIST PROGRAMME (ENS) WITH SIX INTERACTIVE E-LEARNING COURSES ON EARLY NUTRITION BUILDING ON MORE THAN TEN YEARS OF EXPERIENCE WITH GLOBAL E-LEARNING PLATFORMS, EXPERT KNOWLEDGE AND AN INTERNATIONAL NETWORK IN THE SUBJECT FIELD. WE COLLECTED DESCRIPTIVE AND EXPLORATIVE EVALUATION DATA ON USAGE AND LEARNER SATISFACTION WITH A QUESTIONNAIRE AND LOG DATA OVER THREE YEARS AMONG 4003 LEARNERS FROM 48 COUNTRIES. RESULTS: RESULTS SHOW HIGH COMPLETION OF THE ENS PROGRAMME, WITH 85.5% OF LEARNERS FINALIZING THE PROGRAMME AFTER ENROLLMENT INTO THE FIRST OF SIX COURSES. VERY GOOD RESULTS WERE PROVIDED FOR LEARNER SATISFACTION WITH THE COURSES (96.7% OF USERS), FOR INCREASING UNDERSTANDING OF THE TOPIC (97.4%) AND MATCHING THE INDICATED TIME INVESTMENT (94.4%). MOST PREDOMINANT THEMES IN THE OPEN TEXT FIELDS OF USER FEEDBACK QUESTIONNAIRES WERE "INCREASE INTERACTIVITY OR NUMBER OF AUDIO-VISUALS", "CONTENT SUGGESTIONS OR MORE EXAMPLES" AND "TECHNICAL (QUALITY) ISSUES OR NAVIGATION PROBLEMS". CONCLUSIONS: THE ENS PROGRAMME EVALUATION SHOWS HIGH COMPLETION RATES AND LEVEL OF SATISFACTION BY LEARNERS FROM NUMEROUS COUNTRIES. THE DIFFERENT NEEDS FOR CONTINUING MEDICAL EDUCATION (CME) OF HEALTHCARE PROFESSIONALS IN DIVERSE HEALTHCARE SYSTEM SETTINGS CAN BE MET BY A JOINT E-LEARNING QUALIFICATION PROGRAMME. FURTHER OPTIMIZATIONS WILL BE IMPLEMENTED BASED ON USER FEEDBACK. MORE RESEARCH WITH A LEARNING ANALYTICS APPROACH MAY HELP TO FURTHER IDENTIFY THE MOST EFFECTIVE AND EFFICIENT DIDACTIC AND PEDAGOGIC ELEMENTS OF E-LEARNING.
