Project description:IntroductionAlcohol use and suicidality remain serious risks for U.S. youth. Research has established that disparities exist in these outcomes between heterosexual and sexual minority youth. However, research into the associations between alcohol use and suicidality has yet to consider the differential role of sexual orientation.MethodsUsing a pooled, diverse sample from the 2009-2017 Youth Risk Behavior Survey, associations of alcohol use and suicidality by sex and sexual orientation, and changes in these outcomes over time, were investigated. Analyses were conducted in 2019.ResultsSuicidality was highest among nonheterosexuals, who ranged from twofold to sevenfold higher odds to report suicidality across all time points, with the most striking disparities among male sexual minority youth. Rates among all students remained stable or increased over time; notable exceptions included a decrease in suicide attempts among bisexual students. Among all students, current alcohol use was associated with elevated levels of suicidality. For female students, the association between drinking and suicidality did not significantly differ by sexual identity; for male students, it was significant regardless of sexual identity and most pronounced among not sure youth.ConclusionsThese results emphasize the need for additional research into the relationship between contemporaneous alcohol use and suicidality, with attention to differences based on sex, sexual orientation, and other factors that may impact these relationships. There is a particular need for research to examine the temporal nature of the association such that evidence-informed, high-impact interventions can be developed to improve suicidality outcomes among sexual minority youth.

Project description:BackgroundDigital technology and media use is integral to adolescents' lives and has been associated with both positive and negative health consequences. Previous studies have largely focused on understanding technology behaviors and outcomes within adolescent populations, which can promote assumptions about adolescent technology use as homogeneous. Furthermore, many studies on adolescent technology use have focused on risks and negative outcomes. To better understand adolescent digital technology use, we need new approaches that can assess distinct profiles within study populations and take a balanced approach to understanding the risks and benefits of digital technology use.ObjectiveThe purpose of this study was to identify profiles of adolescent technology use within a large study population focusing on four evidence-based constructs: technology ownership and use, parental involvement, health outcomes, and well-being indicators.MethodsAdolescent-parent dyads were recruited for a cross-sectional web-based survey using the Qualtrics (Qualtrics International, Inc) platform and panels. Technology use measures included ownership of devices, social media use frequency, and the Adolescents' Digital Technology Interactions and Importance scale. Parent involvement measures included household media rules, technology-related parenting practices, parent social media use frequency, and the parent-child relationship. Health outcome measures included physical activity, sleep, problematic internet use, and mental health assessments. Well-being indicators included mental wellness, communication, and empathy. We used latent class analysis (LCA) to identify distinct profile groups across the aforementioned 4 critical constructs.ResultsAmong the 3981 adolescent-parent dyads recruited, adolescent participants had a mean age of 15.0 (SD 1.43) years; a total of 46.3% (1842/3981) were female, 67.8% (2701/3981) were White, and 75% (2986/3981) lived in a household with an income above the poverty line. The LCA identified 2 discrete classes. Class 1 was made up of 62.8% (2501/3981) of the participants. Class 1 participants were more likely than Class 2 participants to report family-owned devices, have lower technology importance scores, have household technology rules often centered on content, have positive parent relationships and lower parent social media use, and report better health outcomes and well-being indicators.ConclusionsFindings from this national cross-sectional survey using LCA led to 2 distinct profile groups of adolescent media use and their association with technology use and parent involvement as well as health and well-being outcomes. The two classes included a larger Class 1 (Family-Engaged Adolescents) and a smaller Class 2 (At-Risk Adolescents). The findings of this study can inform interventions to reinforce positive technology use and family support.

Project description:BackgroundDigital media engagement, such as browsing the internet or social media posting, may be associated with cannabis and tobacco product use initiation among adolescents. Whether certain digital media exposure confers greater - or reduced - risk for specific cannabis or tobacco products is unknown.MethodsAdolescents completed surveys on digital media and substance use every 6 months from 2015 to 2017 (4 waves). Self-reported digital media use (14 items) was classified into six subcategories (e.g., "social media posting," "reading news/articles & browsing photos"). Random-effect repeated-measures regression models examined the association of exposure to each digital media subcategory with subsequent cannabis or tobacco product use initiation in the next 6 months, among baseline cannabis and tobacco never-users (n = 1841; n = 1558, respectively).ResultsHigh frequency digital media use (multiple times/day) of "social media posting" (vs. no high frequency use; OR = 1.95; 95%CI:1.20-3.17) and "checking in" (OR = 1.71; 95%CI:1.23-2.38) was associated with greater odds of any cannabis product use initiation 6 months later. "Reading news/articles & browsing photos" was associated with decreased odds of initiation (OR = 0.52; 95%CI:0.34-0.79). "Checking in" and "reading news/articles & browsing photos" were similarly associated with any tobacco use initiation. "Chatting and shopping" was associated with greater odds (OR = 4.63; 95%CI:1.53-14.06) of e-cigarette initiation, but not of other product use initiation.ConclusionsSome subcategories of digital media use conferred increased odds, others conferred reduced odds, and others were not associated with cannabis and tobacco use initiation. Research exploring mechanisms that put users of specific digital media at greater risk for substance use initiation is warranted.

Project description:BackgroundAlthough adolescents commonly use digital media and consume alcohol , longitudinal evidence of the association between these behaviors is scant. This study examined the association between the frequency of digital media use and the subsequent initiation or progression of alcohol use. We also examined whether these associations were moderated by gender and race/ethnicity.MethodsThe study included 2,473 adolescents from a prospective cohort in the Los Angeles, CA area who were surveyed in fall 2015 (11th grade, baseline for the current study) and every 6 months through the end of high school (Spring 2017, 12th grade). At baseline, youth self-reported the total number of 14 digital media activities (e.g., checking social media, streaming music/videos, texting) they engaged in at a high frequency (i.e., many times a day) over the past week. Scores ranged from 0 (i.e., no reported high-frequency digital media use) to 14 (i.e., reported engagement in all 14 digital media activities at a high frequency). Self-report measures of ever using alcohol, number of days of alcohol use in the past 30 days (0 to 30), binge drinking (yes/no), and covariates (i.e., demographics and measures of behavioral health and other substance use) were assessed at each time point.ResultsAmong respondents who at baseline reported never using alcohol (n = 1,214), high-frequency engagement in each additional digital media activity was associated with 4% higher odds of initiating alcohol use (aOR = 1.04, 95% CI: 1.01 to 1.07) across follow-up. Among respondents who at baseline reported ever using alcohol (n = 1,259), baseline high-frequency engagement in each additional digital media activity was associated at follow-up with 3% more days of alcohol use in the past 30 days (aIRR = 1.03, 95% CI: 1.00 to 1.06). Digital media use and binge drinking were not statistically significantly associated at follow-up. There was no evidence of moderation by gender or race/ethnicity.ConclusionsDigital media use frequency was modestly associated with increased risk of initiation and progression of alcohol use in adolescence. Additional research is needed to determine potential mechanisms for these associations.

Project description:Stress generation has potential to account for recurrent suicidal behavior. The current study represents a first step toward evaluating this possibility in a sample of adolescent psychiatric inpatients (n = 99; 79.80% female) followed over six months. At index admission, participants completed baseline measures of depressive symptom severity, suicidal ideation, lifetime history of suicide attempts, and negative life events using a contextual threat life stress interview. Negative life events since baseline were assessed at the follow-up assessment. Consistent with the stress generation hypothesis, lifetime number of suicide attempts prospectively predicted higher rates of dependent, but not independent, stress. Bayesian analyses also yielded substantial support for an association with overall dependent stress, but provided more modest support for specificity to this form of life stress relative to independent stress. Implications of these findings and directions for future research further clarifying the role of stress generation in suicidal behavior are discussed.

Project description:IntroductionThe Air Force uses dental caries risk assessments (CRA) to determine which active duty Air Force (ADAF) members are at high caries risk (HCR) and will benefit from additional preventive and restorative dental care. The purpose of this study is to describe the caries risk of ADAF from 2009 to 2017 and determine how demographic, military, and tobacco-use characteristics affect caries risk.Materials and methodsData from ~300,000 ADAF annual dental examinations from 2009 to 2017 were used. The outcome variable investigated was dental caries risk (high, moderate, or low). Independent variables analyzed were: age, sex, race, education, marital status, military rank, service years, flying status, and tobacco use. Descriptive and multivariable analyses were performed to explore associations between potential risk indicators and caries risk outcomes.ResultsFrom 2009 to 2013, there was a steady decline in ADAF that were diagnosed as low caries risk (LCR), from 80.3% to 67.7%. Since 2013, the prevalence of ADAF that are LCR has remained unchanged at about two-thirds of the force. The proportion of the ADAF that are moderate caries risk (MCR) increased from 15.7% in 2009 to 25.3% in 2013 and remained unchanged affecting about a quarter of the force since then. The proportion that was diagnosed as HCR increased from 3.9% in 2009 to 7.1% in 2013 and declined slightly in 2017 (6.0%). After controlling for other covariates, younger age (<20 years old: odds ratio [OR], 4.4; 95% confidence interval [CI], 3.3-5.8), less time in service (≤4 years: OR, 2.1; 95% CI, 1.7-2.6), junior rank (E-1-E-4: OR, 1.6; 95% CI, 1.3-1.8), less education (high-school graduate: OR, 2.3; 95% CI, 2.0-2.6), using tobacco (Smoker: OR, 1.6; 95% CI, 1.5-1.7), being a nonflyer (OR, 1.2; 95% CI, 1.1-1.3), being male (OR, 1.1; 95% CI, 1.1-1.2), or being black (OR, 1.2; 95% CI, 1.1-1.2) were each associated with being HCR. Among the cohort of Airmen who were LCR at baseline, the majority (75.9%) remained at low risk, but for nearly a quarter (24.1%), their risk of caries increased over 9 years. Among those who were originally MCR in 2009, 61.5% improved to LCR, whereas 4.6% progressed to HCR; among those identified as high risk for caries in 2009, a substantial majority (89.1%) improved over 9 years, but 10.9% remained unchanged.ConclusionsThe prevalence of HCR and MCR service members increased from 2009 to 2013 but has remained consistent since 2013. Overall caries risk in the Air Force is lower compared to previously published findings from 2001 to 2004. This suggests that CRA and prevention programs have been effective at helping to reduce caries prevalence among Airmen. Smoking prevalence among ADAF has also declined substantially over the past 16 years which may contribute to overall caries risk reductions. Using a CRA approach may be an effective tool for helping to identify and develop strategies to manage dental caries risk in patients.

Project description:BackgroundTo address the need to identify potential markers of suicide behavior for adolescents (ages 12-18 years), mass cytometry was used to explore the cellular mechanisms that may underpin immune dysregulation in adolescents with recent suicidal behavior.MethodsPeripheral blood mononuclear cell (PBMC) samples from 10 female adolescents with a recent suicide attempt and 4 healthy female adolescents were used. A panel of 30 antibodies was analyzed using mass cytometry. We used two complementary approaches to 1) identify the cell types that significantly differed between the two groups, and 2) explore differences in the expression profile of markers on the surface of these cells. Mass cytometry data were investigated using (Center for Disease Control, 2021) Opt-SNE for dimension reduced (Curtin and Heron, 2019), FlowSOM for clustering, and (Bridge et al., 2006) EgdeR and SAM for statistical analyses.ResultsOpt-SNE (a data driven clustering analysis) identified 15 clusters of distinct cell types. From these 15 clusters, cluster 5 (classical monocytes) had statistically lower abundance in suicidal adolescents as compared to healthy controls, whereas cluster 7 (gamma-delta T cells) had statistically higher abundance in suicidal adolescents compared to healthy control. Furthermore, across the 15 cell types, chemokine receptors, CXCR3 (cluster 5) and CXCR5 (clusters 4, 5, 7, and 9), had an elevated expression profile in those with a recent suicide attempt versus healthy controls.ConclusionThis report demonstrates the utility of high dimensional cell phenotyping in psychiatric disorders and provides preliminary evidence for distinct immune dysfunctions in adolescents with recent suicide attempts as compared to healthy controls.

Project description:ImportanceModern digital platforms are easily accessible and intensely stimulating; it is unknown whether frequent use of digital media may be associated with symptoms of attention-deficit/hyperactivity disorder (ADHD).ObjectiveTo determine whether the frequency of using digital media among 15- and 16-year-olds without significant ADHD symptoms is associated with subsequent occurrence of ADHD symptoms during a 24-month follow-up.Design, setting, and participantsLongitudinal cohort of students in 10 Los Angeles County, California, high schools recruited through convenience sampling. Baseline and 6-, 12-, 18-, and 24-month follow-up surveys were administered from September 2014 (10th grade) to December 2016 (12th grade). Of 4100 eligible students, 3051 10th-graders (74%) were surveyed at the baseline assessment.ExposuresSelf-reported use of 14 different modern digital media activities at a high-frequency rate over the preceding week was defined as many times a day (yes/no) and was summed in a cumulative index (range, 0-14).Main outcomes and measuresSelf-rated frequency of 18 ADHD symptoms (never/rare, sometimes, often, very often) in the 6 months preceding the survey. The total numbers of 9 inattentive symptoms (range, 0-9) and 9 hyperactive-impulsive symptoms (range, 0-9) that students rated as experiencing often or very often were calculated. Students who had reported experiencing often or very often 6 or more symptoms in either category were classified as being ADHD symptom-positive.ResultsAmong the 2587 adolescents (63% eligible students; 54.4% girls; mean [SD] age 15.5 years [0.5 years]) who did not have significant symptoms of ADHD at baseline, the median follow-up was 22.6 months (interquartile range [IQR], 21.8-23.0, months). The mean (SD) number of baseline digital media activities used at a high-frequency rate was 3.62 (3.30); 1398 students (54.1%) indicated high frequency of checking social media (95% CI, 52.1%-56.0%), which was the most common media activity. High-frequency engagement in each additional digital media activity at baseline was associated with a significantly higher odds of having symptoms of ADHD across follow-ups (OR, 1.11; 95% CI, 1.06-1.16). This association persisted after covariate adjustment (OR, 1.10; 95% CI, 1.05-1.15). The 495 students who reported no high-frequency media use at baseline had a 4.6% mean rate of having ADHD symptoms across follow-ups vs 9.5% among the 114 who reported 7 high-frequency activities (difference; 4.9%; 95% CI, 2.5%-7.3%) and vs 10.5% among the 51 students who reported 14 high-frequency activities (difference, 5.9%; 95% CI, 2.6%-9.2%).Conclusions and relevanceAmong adolescents followed up over 2 years, there was a statistically significant but modest association between higher frequency of digital media use and subsequent symptoms of ADHD. Further research is needed to determine whether this association is causal.

Project description:IntroductionIdentification of modifiable risk factors for suicidal behaviors is a priority for the U.S. Army. This study investigated associations of nicotine dependence with suicidal behaviors among incoming soldiers.MethodsLifetime DSM-IV nicotine dependence, mental disorders, suicidal behaviors, and their ages of onset were retrospectively assessed in the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) New Soldier Study. Discrete-time survival analysis of person-year data from 30,436 soldiers was performed to evaluate associations of nicotine dependence with subsequent suicidal ideation, plans, and attempts. Among respondents with lifetime ideation (n=4,060), models tested associations of nicotine dependence with progression from ideation to first onset of plan, from plan to first attempt, and, among ideators without plans, from ideation to first unplanned attempt. A hierarchy of models incorporated increasing controls for other risk factors. Data were collected in 2011-2012 and analyzed in 2017-2018.ResultsIn models controlling for sociodemographic characteristics, nicotine dependence was associated with onset of all suicidal behaviors (AORs, 2.07-4.08, p<0.001) and with each type of progression of suicidal behavior (AORs, 1.48-2.44, p<0.005). After adjusting for childhood adversities and mental disorders, nicotine dependence remained associated with onset of ideation (AOR=1.27, 95% CI=1.10, 1.46, p=0.001) and attempt (AOR=1.83, 95% CI=1.41, 2.37, p<0.001); and with progression from ideation to unplanned attempt (AOR=2.03, 95% CI=1.17, 1.74, p<0.001).ConclusionsNicotine dependence exhibited associations with onset of suicidal ideation and suicide attempt-and with progression from ideation to unplanned attempt-that were independent of other measured risk factors. Awareness of associations of nicotine dependence with suicidal behaviors may inform risk assessment, facilitate targeting of prevention efforts, and provide further impetus for reducing nicotine dependence.

Project description:ObjectivesThe reported effects of digital media overuse on physical activity among adolescents are inconsistent. This study examined the association between hours of digital media use and lack of moderate-intensity physical exercise (mPE) according to the type of digital media.MethodsThis study included 1,837 middle school students from the iCURE (Internet user Cohort for Unbiased Recognition of gaming disorder in Early Adolescence) study conducted in Korea. Hours spent using digital media were measured by self-reported daily usage time for Internet games, messengers, social media, and watching game streaming on weekdays. Lack of mPE was defined as performing a minimum of 30 minutes at a time less than twice weekly. Multivariable logistic regression analysis stratified by sex was performed.ResultsAmong male students, the group with the highest hours of using either Internet games or watching game streaming was more likely to lack mPE than each non-user group. In contrast, among male students, the group using either messengers or social media had a higher rate of mPE compared to each non-user group. Female students showed no association between hours spent using Internet games, messengers, social media, or watching game streaming and a lack of mPE.ConclusionsAmong male middle school students in Korea, the excessive use of Internet games or watching game streaming was associated with a lack of mPE. Thus, guidelines should be established regarding adolescent use of internet games and watching game streaming.
