To evaluate how geography, ethnicity, ancestry, and race or religion (GEAR) and social determinants of health (SDOH) data are reported and discussed in 3 European pediatric journals and to compare practices between European and American journals.

A retrospective analysis of all original articles that enrolled children (<18 years old) published from January through June 2021 in 3 European pediatric journals: Archives of Disease in Childhood, European Journal of Pediatrics, and Acta Paediatrica. We categorized SDOH using the 5 domains as outlined by the US Healthy People 2030 framework. For each article, we recorded whether GEAR and SDOH were reported in the results and interpreted in the discussion sections. We then compared these European data by χ² tests with data from 3 US pediatric journals.

Of the 320 studied articles, 64 (20%) and 80 (25%) reported GEAR and SDOH data in the results sections, respectively. Of those articles, 32 (50%) and 53 (66.3%) studies interpreted the GEAR and SDOH data in their discussion sections, respectively. On average, articles reported factors from 1.2 GEAR and 1.9 SDOH categories with great variability in the variables collected and data groupings. Articles published in European journals were less likely to report GEAR and SDOH than articles published in US journals (P < .001 for both).

Articles published in European pediatric journals did not commonly report either GEAR or SDOH, and there was wide variation in how data were collected and reported. Harmonization of categories will allow for more accurate interstudy comparisons.
