NLM MeSH Changes to Sexuality Terms and Related Concepts for 2019

Systematic Review of Sexuality Concepts

The 2019 MeSH (Medical Subject Headings) vocabulary was evaluated for inclusion in the Classification index. Several additions and changes were made to the Index and Schedules based on this review. All main index headings are now linked to the 2019 vocabulary in the MeSH Browser. Additional minor updates were made to the Index and Schedules.
