Prospective association between screen use modalities and substance use experimentation in early adolescents.

There are limited large-scale, prospective analyses examining contemporary screen use and substance use experimentation in early adolescents. The current study aimed to determine associations between eight forms of contemporary screen modalities and substance use experimentation one year later in a national cohort of 11-12-year-olds in the United States. The sample consisted of 8006 early adolescents (47.9 % female and 41.6 % racial/ethnic minority) from the prospective cohort data of the Adolescent Brain Cognitive Development (ABCD) Study. Logistic regression analyses were conducted to evaluate the prospective associations between screen time (eight different types and total) in Year 2 and substance use experimentation (alcohol, nicotine, cannabis, any substance use) in Year 3, adjusting for covariates and Year 2 substance use experimentation. Total screen time was prospectively associated with alcohol, nicotine, and cannabis experimentation. Each additional hour spent on social media (AOR 1.20; 95 % CI 1.14-1.26), texting (AOR 1.18; 95 % CI 1.12-1.24), and video chatting (AOR 1.09; 95 % CI 1.03-1.16) was associated with higher odds of any substance experimentation. Social media use and texting were also associated with higher odds of alcohol, cannabis, and nicotine experimentation; however, television/movies, videos, video games, and the internet were not. Moreover, video chatting was associated with higher odds of cannabis and nicotine experimentation. Our findings indicate that digital social connections, such as via social media, texting, and video chatting, are the contemporary screen modalities that are associated with early adolescent substance experimentation. Future research could explore the mechanisms underlying these associations to inform intervention strategies.

Screen use in transgender and gender-questioning adolescents: Findings from the Adolescent Brain Cognitive Development (ABCD) Study.

To assess the association between transgender or gender-questioning identity and screen use (recreational screen time and problematic screen use) in a demographically diverse national sample of early adolescents in the U.S. We analyzed cross-sectional data from Year 3 of the Adolescent Brain Cognitive DevelopmentSM Study (ABCD Study®, N = 9859, 2019-2021, mostly 12-13-years-old). Multiple linear regression analyses estimated the associations between transgender or questioning gender identity and screen time, as well as problematic use of video games, social media, and mobile phones, adjusting for confounders. In a sample of 9859 adolescents (48.8% female, 47.6% racial/ethnic minority, 1.0% transgender, 1.1% gender-questioning), transgender adolescents reported 4.51 (95% CI 1.17-7.85) more hours of total daily recreational screen time including more time on television/movies, video games, texting, social media, and the internet, compared to cisgender adolescents. Gender-questioning adolescents reported 3.41 (95% CI 1.16-5.67) more hours of total daily recreational screen time compared to cisgender adolescents. Transgender identification and questioning one's gender identity was associated with higher problematic social media, video game, and mobile phone use, compared to cisgender identification. Transgender and gender-questioning adolescents spend a disproportionate amount of time engaging in screen-based activities and have more problematic use across social media, video game, and mobile phone platforms.

Association between gender diversity and substance use experimentation in early adolescents.

Gender diversity, encompassing gender identity beyond traditional binary frameworks, has been associated with substance use during adolescence. However, there is a paucity of studies that consider different dimensions of gender diversity. This study investigates associations between multiple dimensions of gender diversity and substance experimentation in early adolescents. Data from 10,092 adolescents aged 12-13 years from the Adolescent Brain Cognitive Development (ABCD) study were used to assess the relationship between gender diversity and substance experimentation. Gender diversity was measured using multiple dimensions, including identity (transgender), felt gender (congruence between gender identity and assigned sex), gender non-contentedness (dissatisfaction with one's gender), gender expression (adherence to gender expression norms), and place on the gender spectrum (masculine to feminine). Substance use was evaluated using self-reported lifetime and new experimentation (past year) of alcohol, nicotine, and cannabis use. Logistic regression models adjusted for sociodemographic factors were analyzed. More gender-diverse responses for felt gender, gender non-contentedness, gender expression, and gender spectrum were associated with higher odds of lifetime alcohol experimentation. More gender-diverse responses for gender identity and gender non-contentedness were associated with higher odds of new nicotine experimentation, and more gender-diverse responses for gender identity, felt gender, gender non-contentedness, and gender expression were associated with higher odds of lifetime and new cannabis experimentation. Gender diversity is differentially associated with new and lifetime substance experimentation in early adolescence. Different dimensions of gender diversity may be uniquely associated with substance use behaviors, highlighting the need for targeted interventions in gender-diverse adolescents.
