Excessive smartphone use has been associated with psychological and sleep\u2010related disturbances. University students, particularly health sciences students, may be especially vulnerable due to academic stress and high digital exposure.<\/jats:p>\n <\/jats:sec>\n \n Objectives<\/jats:title>\n This study aimed to determine the prevalence of nomophobia and insomnia symptoms among health sciences students and to assess the association between nomophobia severity and insomnia symptom severity.<\/jats:p>\n <\/jats:sec>\n \n Methodology<\/jats:title>\n \n A cross\u2010sectional analytical study was conducted among undergraduate health sciences students at Batterjee Medical College (BMC), Jeddah, Saudi Arabia. Data were collected using a structured electronic questionnaire including sociodemographic variables, the Nomophobia Questionnaire (NMP\u2010\n Q<\/jats:italic>\n ), and the Insomnia Severity Index (ISI). A total of 702 participants were included. Descriptive statistics, chi\u2010square test, Spearman's rank correlation, and binary logistic regression analysis were performed.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The mean nomophobia score was 77.21\u00a0\u00b1\u00a031.7. Overall, 96.6% of participants demonstrated nomophobia, with moderate nomophobia being the most prevalent category (45.3%), followed by severe nomophobia (26.1%). The mean insomnia score was 10.86\u00a0\u00b1\u00a05.7, and 71.4% of participants exhibited elevated insomnia symptoms, predominantly at the subthreshold level (46.3%). A statistically significant association was observed between nomophobia and insomnia symptoms (\n p<\/jats:italic>\n \u00a0<\u00a00.001). Using continuous total scores, a weak positive correlation was identified between nomophobia severity and insomnia symptom severity (Spearman's\n \u03c1<\/jats:italic>\n \u00a0=\u00a00.290,\n p<\/jats:italic>\n \u00a0<\u00a00.001). Female gender was significantly associated with higher nomophobia prevalence (\n p<\/jats:italic>\n \u00a0=\u00a00.014). In multivariable logistic regression analysis treating nomophobia as a continuous predictor, each 10\u2010point increase in NMP\u2010\n Q<\/jats:italic>\n score was associated with significantly higher adjusted odds of insomnia symptoms (adjusted odds ratio [AOR]\u00a0=\u00a01.20, 95% confidence interval [CI] 1.13\u20131.27,\n p<\/jats:italic>\n \u00a0<\u00a00.001) after adjustment for sociodemographic factors.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Nomophobia and insomnia symptoms are highly prevalent among health sciences students. A weak but statistically significant association was observed; however, the cross\u2010sectional design and convenience sampling warrant cautious interpretation. These findings highlight the need for interventions promoting healthy smartphone use and sleep hygiene.<\/jats:p>\n
