A June 2017 review sponsored by the European commission as part of a larger project to identify and diminish health inequities, found that LGB are at higher risk of some cancers and that LGBTI were at higher risk of mental illness, and that these risks were not adequately addressed. The causes of health inequities were, according to the review, "i) cultural and social norms that preference and prioritise heterosexuality; ii) minority stress associated with sexual orientation, gender identity and sex characteristics; iii) victimisation; iv) discrimination (individual and institutional), and; v) stigma."
