Sexual Orientation and Gender Identity Reporting in Highly Cited Current Alcohol Research.

Purpose: This study aimed to measure the frequency of high-quality and transparent sexual orientation and gender identity (SOGI) data collection and reporting in highly cited current alcohol use research, using the extant literature to identify community-informed priorities for the measurement of these variables. Methods: A single search to identify alcohol use literature was conducted on PubMed with results restricted to primary research articles published between 2015 and 2022. The 200 most highly cited studies from each year were identified and their titles and abstracts reviewed against inclusion criteria after deduplication. After full-text review, study characteristics and data indicating quality of SOGI reporting were extracted. The fidelity of the results was verified with a random sample before analyses. Results: The final sample comprised 580 records. Few studies reported gender identity (n = 194; 33.4%) and, of these, 7.2% reported the associated gender identity measure. A two-stage approach to measure gender was adopted in 3 studies, one study used an open-ended question with a free-text response option, and 13 studies recorded nonbinary gender identities (reported by 0.9% of the whole sample). Nineteen (3.3%) studies reported sexual orientation and more than half of these provided the sexual orientation measure. Eight of the 20 studies that reported sexual orientation and/or gender identity measures were classified as sexual and gender minority specialist research. Conclusions: Culturally competent SOGI reporting is lacking in highly cited current alcohol research. SOGI measures should be disclosed in future research and should provide free-text response options.
