Reliable epidemiological data are critical for informing public health responses. This study aimed to estimate prevalence and socio-demographic distributions of common DSM-5 mental disorders among first-year university students from 77 universities across 18 countries. Methods Data were collected 2017–2023 in the World Mental Health International College Student Initiative with n = 72,288 university students. Online surveys assessed alcohol use, attention-deficit/hyperactivity, bipolar, drug use, generalized anxiety, major depression, panic, and post-traumatic stress disorders with validated screening scales. Socio-demographics included student age, sex at birth, gender modality, sexual orientation, and parent education. Results The weighted mean response rate was 20.8%. Data were calibrated for differential response rates by sex at birth and age. 65.2% of respondents screened positive for lifetime mental disorders and 57.4% for 12-month mental disorders. Females had higher prevalence of internalizing disorders and males of substance and attention-deficit/hyperactivity disorders. Older age was associated with lower prevalence of most 12-month but not lifetime mental disorders. Non-heterosexual sexual orientation and identifying as transgender were associated with highest prevalence of most mental disorders. Parent education was for the most part uncorrelated with prevalence. Conclusions Although prevalence might have been overestimated due to the low response rate and possible screening scale miscalibration, results nonetheless suggest that mental disorders are highly prevalent among first-year university students worldwide and are widely distributed with respect to socio-demographic characteristics. These findings highlight the need to implement effective interventions to better support first-year university student mental health. 000151662 540__ $$9info:eu-repo/semantics/closedAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000151662 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000151662 700__ $$aRapsey, Charlene 000151662 700__ $$aSampson, Nancy 000151662 700__ $$aLee, Sue 000151662 700__ $$aAlbor, Yesica 000151662 700__ $$aAl-Hadi, Ahmad N. 000151662 700__ $$aAlonso, Jordi 000151662 700__ $$aAl-Saud, Nouf 000151662 700__ $$aAltwaijri, Yasmin 000151662 700__ $$aAndersson, Claes 000151662 700__ $$aAtwoli, Lukoye 000151662 700__ $$aAuerbach, Randy P. 000151662 700__ $$aAyuya, Caroline 000151662 700__ $$aBáez-Mansur, Patricia M. 000151662 700__ $$aBallester, Laura 000151662 700__ $$aBantjes, Jason 000151662 700__ $$aBaumeister, Harald 000151662 700__ $$aBendtsen, Marcus 000151662 700__ $$aBenjet, Corina 000151662 700__ $$aBerman, Anne H. 000151662 700__ $$aBootsma, Erik 000151662 700__ $$aChan, Silver C.N. 000151662 700__ $$aCohut, Irina 000151662 700__ $$aCovarrubias Díaz Couder, María Anabell 000151662 700__ $$aCuijpers, Pim 000151662 700__ $$aDavid, Oana 000151662 700__ $$aDong, Dong 000151662 700__ $$aEbert, David D. 000151662 700__ $$aNobrega, Mireia Felez 000151662 700__ $$aGaete, Jorge 000151662 700__ $$aForero, Carlos García 000151662 700__ $$aGili, Margalida 000151662 700__ $$aGutiérrez-García, Raúl 000151662 700__ $$aHaro, Josep Maria 000151662 700__ $$aHasking, Penelope 000151662 700__ $$aHudec, Kristen 000151662 700__ $$aHunt, Xanthe 000151662 700__ $$aHurks, Petra 000151662 700__ $$aHusky, Mathilde 000151662 700__ $$aJaguga, Florence 000151662 700__ $$aJansen, Leontien 000151662 700__ $$aKählke, Fanny 000151662 700__ $$aKlinkenberg, Elisabeth 000151662 700__ $$aKüchler, Ann-Marie 000151662 700__ $$aLanger, Álvaro I. 000151662 700__ $$aLéniz, Irene 000151662 700__ $$aLiu, Yan 000151662 700__ $$aMac-Ginty, Scarlett 000151662 700__ $$aMartínez, Vania 000151662 700__ $$aMathai, Muthoni 000151662 700__ $$aMcLafferty, Margaret 000151662 700__ $$aMiranda-Mendizabal, Andrea 000151662 700__ $$aMurray, Elaine 000151662 700__ $$aMusyoka, Catherine M. 000151662 700__ $$aNedelcea, Catalin 000151662 700__ $$aNgai, Chun Ho 000151662 700__ $$aNúñez, Daniel 000151662 700__ $$aO'Neill, Siobhan 000151662 700__ $$aPiqueras, Jose A. 000151662 700__ $$aPopescu, Codruta A. 000151662 700__ $$aRobinson, Kealagh 000151662 700__ $$aRodriguez-Jimenez, Tiscar$$uUniversidad de Zaragoza 000151662 700__ $$aScarf, Damian 000151662 700__ $$aSiu, Oi Ling 000151662 700__ $$aStein, Dan J. 000151662 700__ $$aStruijs, Sascha Y. 000151662 700__ $$aTomoiaga, Cristina 000151662 700__ $$aValdés-García, Karla Patricia 000151662 700__ $$avan Luenen, Sanne 000151662 700__ $$aVigo, Daniel V. 000151662 700__ $$aWang, Angel Y. 000151662 700__ $$aWiers, Reinout 000151662 700__ $$aWong, Samuel Y.S. 000151662 700__ $$aKessler, Ronald C. 000151662 700__ $$aBruffaerts, Ronny 000151662 700__ $$aLima, Rodrigo Antunes 000151662 700__ $$aBreet, Elsie 000151662 700__ $$aGarnefski, Nadia 000151662 700__ $$aJacobs, Karen 000151662 700__ $$aKraaij, Vivian 000151662 700__ $$aMunro, Lonna 000151662 700__ $$aMunthali, Richard J. 000151662 700__ $$aPrescivalli, Ana Paula 000151662 700__ $$aRebagliato, Marisa 000151662 700__ $$aRoca, Miquel 000151662 700__ $$aSalemink, Elske 000151662 700__ $$avan der Heijde, Claudia 000151662 7102_ $$14009$$2680$$aUniversidad de Zaragoza$$bDpto.
