The GLOBICS—Global Consortium of Oral Health Birth Cohort Studies (OHBCS)—is a long-lasting international collaborative research group among existing OHBCS, established in response to the Lancet Series on Oral Health, which pointed out the need to shift the global oral health agenda.

A 2-phase online Delphi process sought consensus over research priorities for OHBCS. Participants were identified by mapping existing OHBCS. Fourteen research questions were grouped into 4 thematic areas. A 9-point Likert-type scale was applied. Consensus was achieved if the question had (1) at least 51% of participants scoring a research question as “high priority,” (2) an interquartile range of
