Moreover, it also explored factors that affect each latent profile of the PIUQ-SF-6 score among participants. Methods: A sample of 1477 Vietnamese people, aged 14 to 24, across five provinces participated in the study. Multinomial logistic regression determined factors related to the levels of the Problematic Internet Use Questionnaire Short Form-6 (PIUQ-SF-6) after using latent profile analysis. Results: Participants were divided into three profiles, including those at low, moderate, and high risk of internet addiction. The high-risk latent profile was obtained for 23.1% of adolescents, and the remaining percentages were, respectively, 40.2% and 36.7% of adolescents belonging to the moderate and low-risk groups. Moreover, factors including age, living alone, high Kessler psychological distress scale, excessive time on the internet, living in central cities, and high neighborhood disorder scores were found to be related to moderate- and high-risk internet addiction profiles. Conclusions: Factors analyzed according to individual and social characteristics further explore the reasons underlying increasing internet addiction among Vietnamese youths and inform early interventions.<\/jats:p>","DOI":"10.3390\/ijerph20032090","type":"journal-article","created":{"date-parts":[[2023,1,24]],"date-time":"2023-01-24T01:29:45Z","timestamp":1674523785000},"page":"2090","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Association of Individual and Neighborhood Characteristics to Problematic Internet Use among Youths and Adolescents: Evidence from Vietnam"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6288-7514","authenticated-orcid":false,"given":"Thao Thi Phuong","family":"Nguyen","sequence":"first","affiliation":[{"name":"Institute for Global Health Innovations, Duy Tan University, Da Nang 550000, Vietnam"},{"name":"Faculty of Medicine, Duy Tan University, Da Nang 550000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1975-529X","authenticated-orcid":false,"given":"Ha Ngoc","family":"Do","sequence":"additional","affiliation":[{"name":"Youth Research Institute, Ho Chi Minh Communist Youth Union, Hanoi 100000, Vietnam"},{"name":"Vietnam Youth Academy, Hanoi 100000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8088-4912","authenticated-orcid":false,"given":"Thao Bich Thi","family":"Vu","sequence":"additional","affiliation":[{"name":"Department of Research on Youth\u2019s Organisations and Youth Campaign, Youth Research Institute, Ho Chi Minh Communist Youth Union, Hanoi 100000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Khanh Long","family":"Vu","sequence":"additional","affiliation":[{"name":"Department of Research on Youth\u2019s Organisations and Youth Campaign, Youth Research Institute, Ho Chi Minh Communist Youth Union, Hanoi 100000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiep Duy","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Research on Children\u2019s Issues, Youth Research Institute, Ho Chi Minh Communist Youth Union, Hanoi 100000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dung Tuan","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Research on Youth and Legal Issues, Youth Research Institute, Ho Chi Minh Communist Youth Union, Hanoi 100000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hoang Minh","family":"Do","sequence":"additional","affiliation":[{"name":"Department of Research on Youth Culture and Lifestyle, Youth Research Institute, Ho Chi Minh Communist Youth Union, Hanoi 100000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nga Thi Thu","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Faculty of Social Sciences and Humanities, Hanoi Metropolitan University, Hanoi 100000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ly Thi Bac","family":"La","sequence":"additional","affiliation":[{"name":"Faculty of Preschool Education, Hanoi National University of Education, Hanoi 100000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linh Phuong","family":"Doan","sequence":"additional","affiliation":[{"name":"Institute for Global Health Innovations, Duy Tan University, Da Nang 550000, Vietnam"},{"name":"Faculty of Medicine, Duy Tan University, Da Nang 550000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6474-1137","authenticated-orcid":false,"given":"Tham Thi","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Institute for Global Health Innovations, Duy Tan University, Da Nang 550000, Vietnam"},{"name":"Faculty of Medicine, Duy Tan University, Da Nang 550000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huong Lan Thi","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Institute for Global Health Innovations, Duy Tan University, Da Nang 550000, Vietnam"},{"name":"Faculty of Medicine, Duy Tan University, Da Nang 550000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hoa Thi","family":"Do","sequence":"additional","affiliation":[{"name":"Institute of Health Economics and Technology, Hanoi 100000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7931-2116","authenticated-orcid":false,"given":"Carl A.","family":"Latkin","sequence":"additional","affiliation":[{"name":"Bloomberg School of Public Health, Johns Hopkins University, Baltimore, MD 21205, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cyrus S.
