Objectives: To estimate the proportion of abstracts presented at National Pediatric Research Meetings that are fully-published and describe their design and factors that influence nonpublication. Methods: Descriptive and analytical study including all abstracts presented at National Pediatric Research Meetings (1998-2011). One author per study was identified and asked to complete a survey on its design, publication and factors associated with non-publication. Results: Out of 746 abstracts that were submitted, the authors of 522 (70%) completed the survey. Among these, 84.3% were observational studies and 15.7%, experimental; 34% had received funding. Two hundred and seventeen abstracts were published subsequently (41.5%, 95% confidence interval [CI]: 37.3-45.9). Funded studies had better chances of being published (odds ratio [OR]: 2, 95% CI: 1.4-2.9, p < 0.001). Lack of time, insufficient sample size, and problems with funding were referred as the most common reasons for failure to publish. Conclusion: Among all abstracts presented at National Pediatric Research Meetings, 41.5% were fully published. Lack of time was the most common reason for unpublished studies.
