Participants were recruited using non\u2010probability purposive sampling, and data were collected through face\u2010to\u2010face interviews. Problematic internet use was assessed using the 18\u2010item Bangla\u2010validated Internet Addiction Test (IAT), classifying participants as minimal (18\u201335), moderate (36\u201362), or excessive (63\u201390) users. Associations were examined using Pearson's chi\u2010square tests and multivariable logistic regression. Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were reported.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The mean IAT score was 35.93 (SD: 11.40; range: 18\u201376).

Combining moderate and excessive users, 43.2% (95% CI: 39.9%\u201346.5%) met the study definition of problematic internet use. Male students had 83% higher odds of problematic internet use than female students (aOR = 1.83, 95% CI: 1.37\u20132.44;\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001), while students in general academic disciplines had approximately twice the odds compared with those in health science disciplines (aOR = 2.08, 95% CI: 1.51\u20132.87;\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001).

Male sex and academic discipline were independently associated with problematic internet use. Given the cross\u2010sectional design, non\u2010probability sampling, single\u2010district setting, and limited assessment of behavioral and psychological determinants, findings should not be generalized nationally or interpreted causally. Larger, longitudinal, multi\u2010site studies are needed to confirm these findings and investigate broader determinants.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/hsr2.73233","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T04:54:08Z","timestamp":1790139248000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prevalence of Problematic Internet Use and Sociodemographic Correlates Among Undergraduate Students in Northern Bangladesh: A Cross\u2010Sectional Study"],"prefix":"10.1002","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6179-3372","authenticated-orcid":false,"given":"Md.
