Baseline data encompassing sex, socioeconomic status (family income, parents' education and household crowding), social support (SSA questionnaire), screen time (number of hours spent on screen\u2010based activities), behaviours (sugar consumption and frequency of toothbrushing) and dental caries (DMFT index) was collected through self\u2010administered questionnaires and clinical examinations. OHRQoL (Child Perceptions Questionnaire\u2014CPQ11\u201314) and dental caries incidence were measured at baseline and 2\u2010year follow\u2010up. Structural equation modelling, guided by the Wilson and Cleary conceptual framework, was employed to examine both direct and indirect associations among the study variables.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Increased screen time directly predicted higher dental caries incidence and poor OHRQoL after 2\u2009years. Sugar consumption mediated the association between screen time and dental caries incidence. Incidence of dental caries mediated the association between screen time and OHRQoL. Poor OHRQoL was also directly predicted by dental caries incidence and female sex. Screen time and sugar consumption mediated the association of socioeconomic status and social support with dental caries incidence and OHRQoL.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The findings of this study indicate that spending more time on screen\u2010based activities is significantly associated with a greater consumption of sugar, higher incidence of dental caries and negative impact on OHRQoL among adolescents. These findings underscore the need for targeted strategies aimed at reducing screen time and sugar consumption to mitigate its detrimental effects on oral health and overall quality of life.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/cdoe.70121","type":"journal-article","created":{"date-parts":[[2026,9,26]],"date-time":"2026-09-26T04:59:56Z","timestamp":1790398796000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Screen Time, Dental Caries, and Oral Health\u2010Related Quality of Life in Adolescents Living in Deprived Neighbourhoods in Manaus, Brazil: A Two\u2010Year Follow\u2010Up Study"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-4782-4934","authenticated-orcid":false,"given":"Iana Nogueira","family":"Rego","sequence":"first","affiliation":[{"name":"Le\u00f4nidas e Maria Deane Institute Oswaldo Cruz Foundation Manaus Amazonas Brazil"},{"name":"School of Dentistry Federal University of Amazonas Manaus Amazonas Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0099-9868","authenticated-orcid":false,"given":"Maria Augusta Bessa","family":"Rebelo","sequence":"additional","affiliation":[{"name":"School of Dentistry Federal University of Amazonas Manaus Amazonas Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6299-4432","authenticated-orcid":false,"given":"Mario Vianna","family":"Vettore","sequence":"additional","affiliation":[{"name":"Department of Dentistry and Oral Health Aarhus University Aarhus Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7125-9082","authenticated-orcid":false,"given":"Janete Maria","family":"Rebelo Vieira","sequence":"additional","affiliation":[{"name":"School of Dentistry Federal University of Amazonas Manaus Amazonas Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,25]]},"reference":[{"issue":"24","key":"e_1_2_10_2_1","doi-asserted-by":"crossref","first-page":"1451","DOI":"10.1136\/bjsports-2020-102955","article-title":"World Health Organization 2020 Guidelines on Physical Activity and Sedentary Behaviour","volume":"54","author":"Bull F.
