Background: Smartphones, internet access, and social media represent a new form of problematic behavior and can affect how teens sleep. Methods: A cross-sectional design was employed to examine the prevalence and association of problematic internet use and problematic smartphone use with sleep quality in a non-probability sample of 190 high school students in Mexico. The internet-related experiences questionnaire (IREQ), the mobile-related experiences questionnaire (MREQ), and the Pittsburgh Sleep Quality Index (PSQI) were used. Results: The study revealed that 66% of participants exhibited some form of problematic internet use, primarily in the form of social media use; 68% had some form of problematic smartphone use, and 84% reported poor sleep quality. The PSQI score was most accurately predicted by problematic smartphone use (MREQ), followed by enrollment in the morning school shift, participation in sports, the father’s education level, and knowledge that “smartphone use disturbs sleep”, which together explained 23% of the variation in sleep quality. Conclusions: Excessive smartphone use may negatively affect sleep quality in adolescents. We recommended that interventions be implemented to educate adolescents about appropriate and healthy use of technology, in parallel with the promotion of preventive sleep habits.

Gender-based violence (GBV) and cyber-aggression are growing problems in Mexico, but there is a dearth of information on their associated risks. We aimed to determine the prevalence of dating violence (DV) and cyber-aggression in a public campus and compared students’ acceptability of abusive DV based on their sex and sexual orientation. We employed a cross-sectional design to survey 964 first-year medical students attending a public university. We analyzed who found “acceptable” abusive behaviors from a dating partner and carried out descriptive analyses of sample characteristics by sex. We included 633 women and 331 men. Homosexual and bisexual orientation was lower among women (1.5%, 4.8%) vs. men (16.9%, 7.2%). Of women and men, respectively, 64.2% and 35.8% reported having been in a dating relationship. Experiencing abusive behaviors in the year prior to the study was associated with students’ level of “acceptability”. A total of 43.5% of the students who experienced cyber-aggression did not report any mental health consequences, 32.6% did not seek professional help, and 17.4% reported feeling depressed. Students that accepted emotionally abusive DV behaviors displayed a fourfold risk of experiencing physical abuse. Women and sexual minorities are more at risk of experiencing GBV and DV. More male students reported being victims of cyber-aggression.

The prevalence of eating disorders (ED) has grown in recent decades, associated with sociocultural pressures that partly stem from body stereotypes and increased stress in daily life. However, even though college constitutes a high-risk life stage, this group has received little attention, leaving a significant gap in prevention and early intervention. This cross-sectional and comparative study included 610 Mexican college students aged 18–30 enrolled in two public universities in Mexico: one sample comprised undergraduate students from Yucatan’s UADY (n = 457), and another one from Mexico City’s UNAM (n = 153). Screening tools included the EAT-26, BES, BSQ, DMS, HADS and AUDIT. We determined the frequency of ED symptomatology across both universities. Linear and multiple logistic regressions were conducted to identify factors associated with ED symptomatology. Overall, 19.8% of participants displayed significant ED symptomatology (UADY 15.5%, UNAM 32.7%). Significant ED symptomatology was more common among women (31.8%) than men (11.7%). Non-cisgender students (27.8%) showed a higher frequency than cisgender women (24.7%) and cisgender men (11.2%). High BD was the strongest predictor of significant ED symptomatology (OR = 13.35; 95% CI 6.79–26.26), followed by symptoms of anxiety (OR = 1.11, 95% CI 1.03–1.19). Our findings highlight the need for early screening and targeted interventions among college students in Mexico.
