OBJECTIVE: We assessed the representations of Diversity, Equity and
Inclusion-related terms in the sleep health literature as an indicator of the
importance of Diversity, Equity and Inclusion-related terms for sleep health
research and policies.
METHOD: We performed a bibliometric analysis and a lexical network of these
Diversity, Equity and Inclusion-related terms in previously published
literature.
RESULTS: Based on 4047 abstracts, we found 105 out of 163 DEI-related terms
(63.5%). A total of 2822 (69.7%) articles had at least one Diversity, Equity and
Inclusion-related term. These articles had an average of 4.7 terms per article
(sd: 5.7). Interestingly, the ratio of articles containing at least one
DEI-related term has risen from 61.1% in 2014 to 73.9% in 2024. On the contrary,
the number of Diversity, Equity and Inclusion-related terms in each abstract
remains constant over time.
CONCLUSION: This bibliometric and lexical network study illustrates the
difficulty of making research and promoting sleep health policies without
Diversity, Equity and Inclusion-related terms.
