More comprehensive sex education reduced teen births: Quasi-experimental evidence.

Women in the United States are much more likely to become mothers as teens than those in other rich countries. Teen births are particularly likely to be reported as unintended, leading to debate over whether better information on sex and contraception might lead to reductions in teen births. We contribute to this debate by providing causal evidence at the population level. Our causal identification strategy exploits county-level variation in the timing and receipt of federal funding for more comprehensive sex education and data on age-specific teen birth rates at the county level constructed from birth certificate natality data covering all births in the United States. Our results show that federal funding for more comprehensive sex education reduced county-level teen birth rates by more than 3%. Our findings thus complement the mixed evidence to date from randomized control trials on teen pregnancies and births by providing population-level causal evidence that federal funding for more comprehensive sex education led to reductions in teen births.

Dietary Changes of Youth during the COVID-19 Pandemic: A Systematic Review.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has taken the lives of millions and disrupted countless more worldwide. Simply living through the pandemic has had drastic effects on the health of citizens. Diet, an important aspect of health, has been uniquely affected by the pandemic, although these changes have not been sufficiently studied among youth. OBJECTIVES: The objective of this systematic review was to investigate dietary changes of youth during COVID-19. METHODS: A prespecified literature review was conducted using MEDLINE, EMBASE, Scopus, and CINAHL to identify studies from January 2020 to May 2023 that assessed dietary changes among youth aged ≤20 y compared with before the pandemic. Only quantitative observational studies that were published in English were included. Two authors completed all screening/study selection independently, with disagreements being resolved via discussion. Data extraction was completed by 1 author. Dietary changes were categorized into food groups and habits for analysis purposes. RESULTS: In total, 67 studies met inclusion criteria. Most studies used recall to assess changes (48/67; 71.6%). Most studies found an increase in fruits and vegetables (24/46; 52.2%), grain products (6/11; 54.5%), meat, poultry, and eggs (4/8, 50.0%), diet quality indices and/or overall dietary assessments (7/13, 53.8%), and the frequency of snacking (9/12; 75.0%), whereas generally finding a decrease in ultraprocessed foods (32/53; 60.4%), compared with before the COVID-19 pandemic. Mixed findings or primarily no changes were found for fish and aquatic products, legumes, beans, seeds and nuts, milk and milk products, breakfast consumption, and nutrient intake. CONCLUSIONS: Mostly favorable dietary changes appear to have occurred among youth during COVID-19, although there were several mixed findings and unclear takeaways among the foods and habits under study. The heterogeneity of defining food groups was a noted limitation in the current review.

Glucagon-like peptide-1 receptor agonists in adolescents with overweight or obesity with or without type 2 diabetes multimorbidity-a systematic review and network meta-analysis.

AIM: To synthesize the evidence on the effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in adolescents with overweight or obesity. MATERIALS AND METHODS: For this systematic review and network meta-analysis, we searched five databases and registries until 2 March 2024 for eligible randomized controlled trials (RCTs). The primary outcome was weight change. We did a pairwise meta-analysis to compare GLP-1RAs and placebo, followed by a drug-wise network meta-analysis (NMA) to compare GLP-1RAs against each other. RESULTS: We screened 770 records to include 12 RCTs with 883 participants. The evidence suggests that GLP-1RAs reduced weight (mean difference -4.21 kg, 95% confidence interval [CI] -7.08 to -1.35) and body mass index (BMI; mean difference -2.11 kg/m2, 95% CI -3.60 to -0.62). The evidence on waist circumference, body fat percentage and adverse events (AEs) was very uncertain. The results remained consistent with subgroup analyses for coexisting type 2 diabetes. Longer therapy duration led to a greater reduction in weight and BMI. In the NMA, semaglutide led to the greatest weight reduction, followed by exenatide, liraglutide and lixisenatide. CONCLUSIONS: The evidence suggests that GLP-1RAs reduce most weight-related outcomes in adolescents, with semaglutide being the most efficacious. There is uncertain evidence on body fat and serious AEs, probably due to fewer studies and low incidence, respectively. Larger RCTs with head-to-head comparisons, pragmatic design, adiposity-related outcomes, and economic evaluation can further guide the use and choice of GLP-1RAs.

State laws addressing teen dating violence in US high schools: A difference-in-differences study.

OBJECTIVE: Teen dating violence (TDV) is prevalent with lifelong adverse consequences, and strategies to reduce its burden are needed. Many U.S. states have enacted laws to address TDV in schools, but few studies have examined their effectiveness. This study aimed to assess whether state TDV laws were associated with changes in physical TDV victimization among high school students. METHODS: We used repeated cross-sectional data of high school students from the Youth Risk Behavior Survey across 41 states from 1999 to 2019. Using a difference-in-differences approach with an event study design, we compared changes in past-year physical TDV in states that enacted TDV laws (n = 21) compared to states with no required laws (n = 20). Analyses accounted for clustering at the state-level and state and year-fixed effects. We conducted sensitivity analyses to assess the robustness of our findings. RESULTS: In our sample of 1,240,211 students, the prevalence of past-year physical TDV was 9.2% across all state-years. In 1999, the prevalence of TDV at the state-level ranged from 7.5 to 13.0%; in 2019, the prevalence ranged from 3.7 to 10.5%. There was no significant association between TDV laws and past-year physical TDV. Six or more waves after enactment, we observed a non-significant 1.7% percentage point reduction in TDV in states with TDV laws (95% CI: -3.6 to 0.3 percentage points; p = 0.10). CONCLUSIONS: We found no significant association between enactment of TDV laws and physical TDV among high school students. Further research is needed to understand how TDV laws are implemented and components of TDV laws that may influence effectiveness.

Utilizing social determinants of health to identify most vulnerable neighborhoods-Latent class analysis and GIS map.

OBJECTIVES: Public Health officials are often challenged to effectively allocate limited resources. Social determinants of health (SDOH) may cluster in areas to cause unique profiles related to various adverse life events. The authors use the framework of unintended teen pregnancies to illustrate how to identify the most vulnerable neighborhoods. METHODS: This study used data from the U.S. American Community Survey, Princeton Eviction Lab, and Connecticut Office of Vital Records. Census tracts are small statistical subdivisions of a county. Latent class analysis (LCA) was employed to separate the 832 Connecticut census tracts into four distinct latent classes based on SDOH, and GIS mapping was utilized to visualize the distribution of the most vulnerable neighborhoods. GEE Poisson regression model was used to assess whether latent classes were related to the outcome. Data were analyzed in May 2021. RESULTS: LCA's results showed that class 1 (non-minority non-disadvantaged tracts) had the least diversity and lowest poverty of the four classes. Compared to class 1, class 2 (minority non-disadvantaged tracts) had more households with no health insurance and with single parents; and class 3 (non-minority disadvantaged tracts) had more households with no vehicle available, that had moved from another place in the past year, were low income, and living in renter-occupied housing. Class 4 (minority disadvantaged tracts) had the lowest socioeconomic characteristics. CONCLUSIONS: LCA can identify unique profiles for neighborhoods vulnerable to adverse events, setting up the potential for differential intervention strategies for communities with varying risk profiles. Our approach may be generalizable to other areas or other programs. KEY MESSAGES: What is already known on this topic Public health practitioners struggle to develop interventions that are universally effective. The teen birth rates vary tremendously by race and ethnicity. Unplanned teen pregnancy rates are related to multiple social determinants and behaviors. Latent class analysis has been applied successfully to address public health problems. What this study adds While it is the pregnancy that is not planned rather than the birth, access to pregnancy intention data is not available resulting in a dependency on teen birth data for developing public health strategies. Using teen birth rates to identify at-risk neighborhoods will not directly represent the teens at risk for pregnancy but rather those who delivered a live birth. Since teen birth rates often fluctuate due to small numbers, especially for small neighborhoods, LCA may avoid some of the limitations associated with direct rate comparisons. The authors illustrate how practitioners can use publicly available SDOH from the Census Bureau to identify distinct SDOH profiles for teen births at the census tract level. How this study might affect research, practice or policy These profiles of classes that are at heightened risk potentially can be used to tailor intervention plans for reducing unintended teen pregnancy. The approach may be adapted to other programs and other states to prioritize the allocation of limited resources.

Emotional and behavioural difficulties among children and adolescents attending "ART teen clubs" in Mzuzu City in northern Malawi: a cross-sectional study.

BACKGROUND: While triple anti-retroviral therapy (ART) has improved HIV-infected children surviving into adolescence and adulthood, these children remain vulnerable to HIV-related psychological disturbance due to both the direct HIV infection effects on the brain and indirect effects related to coping with a range of medical, psychological and social stresses associated with HIV, which makes it vital to identify their mental health needs. This study assessed the emotional and behavioural challenges of HIV perinatally infected children and adolescents with a completed disclosure process attending "ART teen club" in Malawi. METHODS: A cross-sectional descriptive study design was conducted to obtain quantitative descriptive descriptions of emotional and behavioural challenges among HIV-infected children and adolescents between 10 and 22 years of age. They were interviewed on their family socio-demographic characteristics, clinical characteristics as well as emotional, conduct, hyperactivity, peer and prosocial problems using the Chichewa version of the Strengths and Difficulties Questionnaire. Data were analyzed using descriptive analysis and logistic regression. RESULTS: Based on the four-band categorization of the SDQ, higher scores for total difficulties score were observed in 72.9% of the children. According to the subscales of the SDQ, results show that children had higher scores in peer problems (62.8%), emotional (68.2%), conduct (68.6%) and prosocial (57.8%) subscales while lower scores were identified in the hyperactivity (16.6%) subscale. Results show that within each level, males are having lower frequencies as compared to females. Results from multivariate binary logistic regression indicate that those with a single parent or not as well as the WHO HIV clinical stage had an impact on the mental health status of the children. Children who do not have a single parent (AOR 3.404; 95% CI:1.563-7.416, p = 0.002) had 3.404 odds of having abnormal mental health status unlike those children with a single parent and children who were in WHO HIV clinical stage 2 (AOR 2.536; 95% CI:1.005-6.395, p = 0.049) or 3 and 4 (AOR 8.459; 95% CI:1.5.820-10.544, p < 0.001) had more odds of having the mental disorder as compared with those children in WHO HIV clinical stage 1. CONCLUSION: The findings of this research underscore the multifaceted nature of mental well-being among children and adolescents living with HIV. Elevated scores in total difficulties, emotional, conduct, and peer problems signify areas of concern, while disparities in hyperactivity and prosocial behavior highlight the nuanced nature of their behavioral challenges. Recognizing the inadequacy of a one-size-fits-all approach, the research emphasizes the necessity of a comprehensive strategy, incorporating factors like religious background, family structure, and clinical HIV stage. Furthermore, the role of "ART teen clubs" in this context is pivotal. Beyond addressing identified risk factors, these clubs must actively foster resilience. Creating an inclusive environment, tapping into individual strengths, and nurturing a sense of community are vital components. By adopting such a holistic approach, Teen support clubs can significantly contribute to the overall mental well-being of adolescents living with HIV, enabling them to navigate challenges effectively and thrive amidst their circumstances.

Comparison of the Skindex-Teen and the Skindex-29 quality of life survey instruments in a predominantly American Indian adolescent population.

BACKGROUND/OBJECTIVES: The Skindex-29 and Skindex-Teen assess dermatology-related quality of life among adults and adolescents, respectively. This study directly compared the same adolescents' responses to the Skindex-29 relative to Skindex-Teen in a predominantly American Indian and/or Alaska Native population. This population is underrepresented in medical research. Although skin-related quality-of-life issues are widespread, American Indian and/or Alaska Native adolescents are not well-represented in related studies. METHODS: Data were collected in-person by self-report survey at two regional powwows in Denver, Colorado in 2021 and 2022. Respondents completed the full Skindex-29 and Skindex-Teen (40 unique items total). RESULTS: Eighty-six adolescents, 12-17 years old, completed the survey. The majority (70.9%, 61/86) of respondents self-identified as American Indian and/or Alaska Native. Analyses were conducted with all respondent survey data. Nearly two-thirds (64.0%, 55/86) of our respondents had a Skindex-29 score that revealed their quality of life was impaired at least mildly by skin disease. The Skindex-29 and Skindex-Teen demonstrated good reliability; there was substantial concordance between responses to the two measures (r values ranged from 0.88 to 0.97 for similar subscales). Compared to younger adolescents (aged 12-14), older adolescents (aged 15-17) reported worse dermatology-related quality of life and emotional toll based on higher Skindex-29 total, Skindex-Teen total, Skindex-29 Emotional subscale, and Skindex-Teen Psychosocial Functioning subscale scores. CONCLUSIONS: American Indian and/or Alaska Native adolescents suffer from skin-related quality-of-life issues. The Skindex-Teen and Skindex-29 generated similar information regarding quality of life in young patients with skin disease. While the Skindex-Teen may be slightly more relevant to adolescents, these surveys were highly concordant. Both the Skindex-Teen and Skindex-29 exhibited frequent "never" responses to questions about impact of skin conditions on relationships with others and tendencies to stay home. Thus, careful attention should be paid to such questions to ensure their relevance to adolescents.

Effects of a Digital Mental Health Intervention on Perceived Stress and Rumination in Adolescents Aged 13 to 17 Years: Randomized Controlled Trial.

BACKGROUND: Although adolescents report high levels of stress, they report engaging in few stress management techniques. Consequently, developing effective and targeted programs to help address this transdiagnostic risk factor in adolescence is particularly important. Most stress management programs for adolescents are delivered within schools, and the evidence for these programs is mixed, suggesting a need for alternative options for stress management among adolescents. OBJECTIVE: The aim of the study is to test the short-term effects of a self-guided digital mental health intervention (DMHI) designed for adolescents on perceived stress and rumination (ie, brooding). METHODS: This was a 12-week, 2-arm decentralized randomized controlled trial of adolescents aged 13 to 17 years who presented with elevated levels of perceived stress and brooding. Participants were randomly assigned to engage with a self-guided DMHI (Happify for Teens) or to a waitlist control. Participants assigned to the intervention group were given access to the program for 12 weeks. Happify for Teens consists of various evidence-based activities drawn from therapeutic modalities such as cognitive behavioral therapy, positive psychology, and mindfulness, which are then organized into several programs targeting specific areas of concern (eg, Stress Buster 101). Participants in the waitlist control received access to this product for 12 weeks upon completing the study. Participants in both groups completed measures of perceived stress, brooding, optimism, sleep disturbance, and loneliness at baseline, 4 weeks, 8 weeks, and 12 weeks. Changes in outcomes between the intervention and waitlist control groups were assessed using repeated-measures multilevel models. RESULTS: Of the 303 participants included in data analyses, 132 were assigned to the intervention and 171 to the waitlist. There were significantly greater improvements in the intervention condition for perceived stress (intervention: B=-1.50; 95% CI -1.82 to -1.19; P<.001 and control: B=-0.09; 95% CI -0.44 to 0.26; P=.61), brooding (intervention: B=-0.84; 95% CI -1.00 to -0.68; P<.001 and control: B=-0.30; 95% CI -0.47 to -0.12; P=.001), and loneliness (intervention: B=-0.96; 95% CI -1.2 to -0.73; P<.001 and control: B=-0.38; 95% CI: -0.64 to -0.12; P=.005) over the 12-week study period. Changes in optimism and sleep disturbance were not significantly different across groups (Ps≥.096). CONCLUSIONS: Happify for Teens was effective at reducing perceived stress, rumination, and loneliness among adolescents over 12 weeks when compared to a waitlist control group. Our data reveal the potential benefits of DMHIs for adolescents, which may present a more scalable, destigmatized, and cost-effective alternative to school-based programs.

Moving Biosurveillance Beyond Coded Data Using AI for Symptom Detection From Physician Notes: Retrospective Cohort Study.

BACKGROUND: Real-time surveillance of emerging infectious diseases necessitates a dynamically evolving, computable case definition, which frequently incorporates symptom-related criteria. For symptom detection, both population health monitoring platforms and research initiatives primarily depend on structured data extracted from electronic health records. OBJECTIVE: This study sought to validate and test an artificial intelligence (AI)-based natural language processing (NLP) pipeline for detecting COVID-19 symptoms from physician notes in pediatric patients. We specifically study patients presenting to the emergency department (ED) who can be sentinel cases in an outbreak. METHODS: Subjects in this retrospective cohort study are patients who are 21 years of age and younger, who presented to a pediatric ED at a large academic children's hospital between March 1, 2020, and May 31, 2022. The ED notes for all patients were processed with an NLP pipeline tuned to detect the mention of 11 COVID-19 symptoms based on Centers for Disease Control and Prevention (CDC) criteria. For a gold standard, 3 subject matter experts labeled 226 ED notes and had strong agreement (F1-score=0.986; positive predictive value [PPV]=0.972; and sensitivity=1.0). F1-score, PPV, and sensitivity were used to compare the performance of both NLP and the International Classification of Diseases, 10th Revision (ICD-10) coding to the gold standard chart review. As a formative use case, variations in symptom patterns were measured across SARS-CoV-2 variant eras. RESULTS: There were 85,678 ED encounters during the study period, including 4% (n=3420) with patients with COVID-19. NLP was more accurate at identifying encounters with patients that had any of the COVID-19 symptoms (F1-score=0.796) than ICD-10 codes (F1-score =0.451). NLP accuracy was higher for positive symptoms (sensitivity=0.930) than ICD-10 (sensitivity=0.300). However, ICD-10 accuracy was higher for negative symptoms (specificity=0.994) than NLP (specificity=0.917). Congestion or runny nose showed the highest accuracy difference (NLP: F1-score=0.828 and ICD-10: F1-score=0.042). For encounters with patients with COVID-19, prevalence estimates of each NLP symptom differed across variant eras. Patients with COVID-19 were more likely to have each NLP symptom detected than patients without this disease. Effect sizes (odds ratios) varied across pandemic eras. CONCLUSIONS: This study establishes the value of AI-based NLP as a highly effective tool for real-time COVID-19 symptom detection in pediatric patients, outperforming traditional ICD-10 methods. It also reveals the evolving nature of symptom prevalence across different virus variants, underscoring the need for dynamic, technology-driven approaches in infectious disease surveillance.

Digital Food Frequency Questionnaire Assessing Adherence to the Norwegian Food-Based Dietary Guidelines and Other National Lifestyle Recommendations: Instrument Validation Study.

BACKGROUND: Valid assessment tools are needed when investigating adherence to national dietary and lifestyle guidelines. OBJECTIVE: The relative validity of the new digital food frequency questionnaire, the DIGIKOST-FFQ, against 7-day weighed food records and activity sensors was investigated. METHODS: In total, 77 participants were included in the validation study and completed the DIGIKOST-FFQ and the weighed food record, and of these, 56 (73%) also used the activity sensors. The DIGIKOST-FFQ estimates the intake of foods according to the Norwegian food-based dietary guidelines (FBDGs) in addition to lifestyle factors. RESULTS: At the group level, the DIGIKOST-FFQ showed good validity in estimating intakes according to the Norwegian FBDG. The median differences were small and well below portion sizes for all foods except "water" (median difference 230 g/day). The DIGIKOST-FFQ was able to rank individual intakes for all foods (r=0.2-0.7). However, ranking estimates of vegetable intakes should be interpreted with caution. Between 69% and 88% of the participants were classified into the same or adjacent quartile for foods and between 71% and 82% for different activity intensities. The Bland-Altman plots showed acceptable agreements between DIGIKOST-FFQ and the reference methods. The absolute amount of time in "moderate to vigorous intensity" was underestimated with the DIGIKOST-FFQ. However, estimated time in "moderate to vigorous intensity," "vigorous intensity," and "sedentary time" showed acceptable correlations and good agreement between the methods. The DIGIKOST-FFQ was able to identify adherence to the Norwegian FBDG and physical activity recommendations. CONCLUSIONS: The DIGIKOST-FFQ gave valid estimates of dietary intakes and was able to identify individuals with different degrees of adherence to the Norwegian FBDG and physical activity recommendations. Moderate physical activity was underreported, water was overreported, and vegetables showed poor correlation, which are important to consider when interpreting the data. Good agreement was observed between the methods in estimating dietary intakes and time in "moderate to vigorous physical activity," "sedentary time," and "sleep."

High School Follow-Up of the Dating Matters® RCT: Effects on Teen Dating Violence and Relationship Behaviors.

Teen dating violence (TDV) is a significant public health problem that can have lifelong consequences. Using a longitudinal, cluster randomized controlled trial (RCT), this study examines whether the Dating Matters comprehensive prevention model, implemented in middle school, prevented TDV and negative relationship behaviors and promoted positive relationship behaviors in high school (9th-11th grades), when compared with a standard of care intervention. Dating Matters includes programs for sixth to eighth grade youth and their parents, training for school staff, a youth communications program, and policy and data activities implemented in the community. Self-report survey data were collected from students in 46 middle schools that were randomly assigned to condition within site. Students completed two surveys (fall and spring) in each middle school grade and a single survey in the spring of each high school grade. This study examined self-reported TDV perpetration and victimization, use of negative conflict resolution strategies, and positive relationship skills in the high school follow-up. While varying patterns emerged, latent panel models demonstrated significant program effects for all outcomes. Dating Matters students reported 19% reduced risk for TDV perpetration, 24% reduced risk for TDV victimization, 7% reduced risk for use of negative conflict strategies, and 3% more use of positive relationship skills, on average across time and cohort, than standard of care students. On average, Dating Matters, implemented in middle school, continued to be more effective at reducing TDV perpetration, TDV victimization, and use of negative conflict resolution strategies in high school than an evidence-based comparison program.Trial Registration: clinicaltrials.gov Identifier: NCT01672541.

The roles of dating and victimization on adverse mental health among teens: Survey findings during the COVID-19 pandemic.

INTRODUCTION: The relationship between romantic involvement, dating violence, other victimizations, and mental health among adolescents in the context of the COVID-19 pandemic is understudied. METHODS: This study analyzed 2021 survey data collected from a representative sample of 9th-12th grade students (n = 10,792) from 24 high schools in a US Midwestern state. Most respondents identified as White, heterosexual, and US-born, with more than three-quarters aged 15-17 years. Guided by the poly-victimization framework, this study explored: (a) How do youth victimizations and mental health concerns differ by their experience of dating and dating violence? (b) What are the associations between youth mental health concerns, victimizations, and dating? RESULTS: Youths reported mental health concerns and victimizations at considerable rates during the COVID-19 pandemic when in-person interactions were limited. Those who experienced dating violence were at a higher risk of reporting other victimizations (i.e., unwanted sexual comments, unwanted sexual contact, sexual photos/videos, sex trading for compensation, discrimination, and bullying). The number of victimizations demonstrated a cumulative effect on teen mental health. Most individual victimizations showed significant net associations with mental health concerns, even when controlling for other differing victimizations. CONCLUSIONS: Dating violence plays a critical role in the interconnectedness of victimizations, and the number of victimizations has a cumulative effect on teen mental health. The high prevalence of youth victimizations during the time when in-person interactions were limited suggests that victimizations may transfer from in-person forms to virtual forms and occur offline. Implications for individual and community prevention and interventions are discussed.

Associations between Adolescent Marijuana Use, Driving after Marijuana Use and Recreational Retail Sale in Colorado, USA.

OBJECTIVE: We investigated associations between the retail distribution of recreational marijuana in Colorado and (i) past 30-day marijuana use and (ii) driving after marijuana use (DAMU) among a representative sample of public high school students using four waves of data from a state surveillance system. METHODS: Past 30-day marijuana use was assessed among all sampled students (n = 85,336). DAMU was assessed among students 15 years or older who indicated driving (n = 47,518). Modified Poisson regression with robust variance estimates was used to estimate prevalence ratios (PR) comparing the pre-distribution (2013) and post-distribution (2015, 2017, 2019) periods for marijuana-related behaviors. Frequency of behavioral engagement was assessed using a multinomial approach. RESULTS: An estimated 20.3% of students engaged in past 30-day marijuana use and 10.5% of student drivers engaged in DAMU. Retail distribution of recreational marijuana was not significantly associated with the prevalence of any marijuana use or DAMU. However, it was associated with 1.16 (95% CI: 1.04-1.29) times the prevalence of using marijuana one or two times in the last 30 days, 1.27 (1.03, 1.55) times the prevalence of DAMU one time, and 0.82 (0.69, 0.98) times the prevalence of DAMU six or more times. No significant associations were observed for the remaining frequency categories. CONCLUSIONS: Approximately 1 in 10 students who drive reported DAMU. Varying prevalence in the frequency of past 30-day marijuana use and DAMU was observed following the retail distribution of recreational marijuana in Colorado. Care should be taken to properly educate adolescent drivers regarding the dangers of DAMU.

P.A.V.I.A. Study: Pervasiveness and Associated Factors of Video Slot Machine Use in a Large Sample of Italian Adolescents.

Video slot machines (VSM) are considered a particularly harmful gambling format; however, scant data is available on their use among underage Italian individuals. Two surveys were conducted in 2018 and 2022 involving 7,959 underage high school students (57.8% female) in Pavia, Northern Italy. We estimated adjusted odds ratios (aOR) and corresponding 95% confidence intervals (CI) for lifetime experience and current regular (at least monthly) use of VSM, according to family, educational and behavioral factors. Overall, participants reporting lifetime VSM experience were 13.2% (95% CI: 12.5 - 13.9), 15.2% (95% CI: 14.0-16.4%) in 2018, and 12.0% (95% CI: 11.1-13.0%) in 2022. Current regular VSM users were 1.4% (95% CI: 1.1-1.7) in total, 1.2% (95% CI: 0.8-1.6%) in 2018 and 1.5% (95% CI: 1.1-1.8%) in 2022. VSM lifetime experience and current regular use were significantly more frequent in males (aORs: 1.55 and 4.81, respectively), students who failed a year (aORs: 2.07 and 3.44), or with daily gambling parents/siblings (aORs: 2.83 and 4.86). Lifetime use of alcohol, tobacco, or illicit substances was significantly directly associated with lifetime VSM use (aORs between 2.64 and 4.75); monthly alcohol, tobacco, or illicit substances use was significantly directly associated with current regular VSM use (aORs between 4.47 and 18.21). Sexting and voluntary self-injury were significantly more frequent among VSM lifetime/current regular users. VSM use, which is directly associated with other risky behaviors, may be pervasive among Italian minors. Such public health concern calls for legislative enforcements and integrated multidisciplinary health promotion and prevention strategies.

Examining Patterns and Predictors of ADHD Teens' Skill-Learning Trajectories During Enhanced FOrward Concentration and Attention Learning (FOCAL+) Training.

OBJECTIVE: Examine patterns and predictors of skill learning during multisession Enhanced FOrward Concentration and Attention Learning (FOCAL+) training. BACKGROUND: FOCAL+ teaches teens to reduce the duration of off-road glances using real-time error learning. In a randomized controlled trial, teens with ADHD received five sessions of FOCAL+ training and demonstrated significant reductions in extended glances (>2-s) away from the roadway (i.e., long-glances) and a 40% reduced risk of a crash/near-crash event. Teens' improvement in limiting long-glances as assessed after each FOCAL+ training session has not been examined. METHOD: Licensed teen (ages 16-19) drivers with ADHD (n = 152) were randomly assigned to five sessions of either FOCAL+ or modified standard driver training. Teens completed driving simulation assessments at baseline, after each training session, and 1 month and 6 months posttraining. Naturalistic driving was monitored for one year. RESULTS: FOCAL+ training produced a 53% maximal reduction in long-glances during postsession simulated driving. The number of sessions needed to achieve maximum performance varied across participants. However, after five FOCAL+ training sessions, number of long-glances was comparable irrespective of when teens achieved their maximum performance. The magnitude of reduction in long-glances predicted levels of long-glances during simulated driving at 1 month and 6 months posttraining but not naturalistic driving outcomes. FOCAL+ training provided the most benefit during training to teens who were younger and had less driving experience. CONCLUSION: FOCAL+ training significantly reduces long-glances beginning at the 1st training session. APPLICATION: Providing five FOCAL+ training sessions early on during teen driving may maximize benefit.

Principal Components Analysis of Driving Simulator Variables in Novice Drivers.

Objective: Although driving simulators are powerful tools capable of measuring a wide-ranging set of tactical and operational level driving behaviors, comparing these behaviors across studies is problematic because there is no core set of driving variables to report when assessing driving behavior in simulated driving scenarios. To facilitate comparisons across studies, researchers need consistency in how driving simulator variables combine to assess driving behavior. With inter-study consistency, driving simulator research could support stronger conclusions about safe driving behaviors and more reliably identify future driver training goals. The purpose of the current study was to derive empirically and theoretically meaningful composite scores from driving behaviors of young people in a driving simulator, utilizing driving data from across a variety of driving environments and from within the individual driving environments. Method: One hundred ninety adolescent participants aged 16 years or 18 years at enrollment provided demographic data and drove in a high-fidelity driving simulator. The simulated scenario included 4 distinct environments: Urban, Freeway, Residential, and a Car Following Task (CFT). A Principal Components Analysis (PCA) was conducted on the variable output from the driving simulator to select optimal factor solutions and loadings both across the multi-environmental drive and within the four individual driving environments. Results: The PCA suggested two components from the multi-environmental simulated drive: vehicle control and speed. The individual driving environments also indicated two components: vehicle control and tactical judgment. Conclusion: These findings are among the first steps for identifying composite driving simulator variables to quantify theoretical conceptualizations of driving behavior. Currently, driving behavior and performance measured by driving simulators lack "gold standards" via driving scores or benchmarks. The composites derived in this analysis may be studied for further use where driving behavior standards are increasingly sought by clinicians and practitioners for a variety of populations, as well as by parents concerned about the readiness of their novice driving teen.

Maternal depression, psychosocial stress and race/ethnicity: examining barriers to breastfeeding for young mothers.

BACKGROUND: Breastfeeding has a positive impact on child and maternal health outcomes. Black and Latina women and adolescent mothers have lower rates of breastfeeding initiation and continuance in the U.S. Maternal depression and psychosocial stressors may contribute to reduced rates of breastfeeding. The current study aims to better understand behaviours and associated factors related to breastfeeding in a diverse group of adolescent mothers attending a teen-tot clinic for postpartum and infant well care. METHODS: Participants were 191 mother-infant dyads. Mother's age ranged from 13 to 25, and 54% of mothers identified as Latina, 22% Black, 11% more than one race and 5% white. Demographic information and breastfeeding behaviour were abstracted from the medical record. Rates of postpartum mood/anxiety symptoms and psychosocial stressors were obtained from screening measures completed at medical visits. RESULTS: Analyses revealed that 87% of adolescent mothers in the sample initiated breastfeeding at birth and the racial/ethnic breakdown of those mothers closely mirrored the overall population (58% Hispanic or Latina, 17% Black, 10% more than one race, 5% white). At 2 months postpartum, only 41% of the population was still breastfeeding. Mothers with significant mood/anxiety symptoms at the newborn visit were more likely to be breastfeeding at the 1- and 2-month visits. Mothers with psychosocial stressors at the newborn visit were less likely to be breastfeeding at the 1- and 2-month visits. CONCLUSION: Efforts to promote health equity through breastfeeding for at-risk mothers must occur within the first few weeks postpartum and must consider associated factors including postpartum mood/anxiety symptoms and psychosocial stressors.

Trends in Adolescent Human Papillomavirus Vaccination and Parental Hesitancy in the United States.

BACKGROUND: Human papillomavirus (HPV) vaccination coverage remains suboptimal in the United States, underscoring the importance of monitoring trends in vaccine hesitancy. METHODS: Cross-sectional data from the 2011-2020 National Immunization Survey-Teen were used to assess trends in HPV vaccination initiation among 13-17-year-olds, parental intent to initiate vaccination, and primary reasons for parental hesitancy. RESULTS: Among all sex and race and ethnicity groups, the prevalence of HPV vaccination initiation increased over time, but parental intent to vaccinate against HPV for unvaccinated teens remained consistently low (≤45%). Among hesitant parents, "safety concerns" increased in nearly all demographic groups, with the greatest increases observed for non-Hispanic white female and male teens and no change for non-Hispanic black female teens. In 2019-2020, parents of unvaccinated non-Hispanic white teens were least likely to intend on vaccinating their teens, and the most common reason for hesitancy varied by sex and race and ethnicity (eg, "safety concerns" for white teens and "not necessary" for black female teens). CONCLUSIONS: Although HPV vaccination initiation increased over time, a substantial fraction of parents remain hesitant, and trends in their reason varied by sex and race and ethnicity. Health campaigns and clinicians should address vaccine safety and necessity.

Adolescent vaccination against human papillomavirus (HPV) is a critical tool for cancer prevention. We analyzed trends in HPV vaccination initiation among adolescents aged 13­17 years and trends in parental hesitancy to initiate HPV vaccination for their teen, using data from a national survey in the United States. Between 2011­2012 and 2019­2020, adolescent HPV vaccination initiation increased over time for both female teens (from 53.4% to 75.2%) and male teens (from 14.5% to 71.5%). However, the majority of parents/guardians of unvaccinated teens did not intend to vaccinate their teen against HPV (ie, were vaccine hesitant), and this was consistent over time in all sex and race and ethnicity groups. Among hesitant parents, the proportion reporting safety concerns as their main reason for being hesitant increased over time in nearly all demographic groups, with the greatest increases in this reasoning observed for white teens. In 2019­2020, parents of unvaccinated white teens were most likely to be vaccine hesitant. The most common reason for being vaccine hesitant also differed by sex and race and ethnicity. Although HPV vaccination has been shown to be safe and effective, HPV vaccination coverage remains suboptimal, and a substantial fraction of parents/guardians continue to be hesitant to adolescent HPV vaccination.

Sexual violence in early adolescence is associated with subsequent teen pregnancy and parenthood.

Being a victim of sexual violence (SV) is associated with risk for teen pregnancy in cross-sectional research. However, longitudinal data are necessary to determine if SV victimization plays a causal role in early pregnancy. To address this gap in research, we test whether experiencing SV victimization in early adolescence is associated with pregnancy and having children by mid-adolescence. The current sample comprised 4594 youth (58% female; 51% Hispanic; 39% Black) attending 44 schools in the southern United States. Self-reported data were collected via audio computer-assisted self-interview (ACASI) when students were in 7th or 8th grade and again approximately 24 months later. Approximately 2.9% of boys and 8.2% of girls reported SV victimization at baseline. At follow-up, 3.4% of boys and 4.0% of girls reported being involved with one or more pregnancies; 1.1% of boys and girls reported having one or more children. Being a victim of SV at baseline was associated with pregnancy and having a child at follow-up for girls. SV was not related to outcomes among boys. The present findings indicate that girls victimized by SV are at risk of becoming pregnant and becoming teen parents. The combined sequelae of SV and teen pregnancy impair health, economic, and social functioning across the lifespan and carry forward into future generations. Future research should explore mechanisms through which victimization confers risk for pregnancy to inform prevention strategies.

Adolescent asthma management self-efficacy and responsibility: impact on asthma control and quality-of-life.

OBJECTIVE: The purpose of this study was to investigate the extent to which adolescent asthma management self-efficacy, outcome expectations, and asthma responsibility were associated with asthma control and quality-of-life. Adolescent self-efficacy and outcome expectations are important components of social cognitive theory, which guided this research. METHODS: English- and Spanish-speaking adolescents ages 11-17 with persistent asthma were recruited at four pediatric clinics. Adolescents were interviewed and parents completed questionnaires. Multiple linear regression was used to analyze the data. RESULTS: Three hundred and fifty-nine adolescents were recruited. Older adolescent age, male gender, and higher adolescent asthma management self-efficacy were significantly associated with higher adolescent responsibility; outcome expectations were not significantly associated with responsibility. Adolescent ratings of their own responsibility were higher than parent ratings of their child's responsibility for almost all asthma management tasks. Adolescents with higher reported asthma management self-efficacy were significantly more likely to have better quality-of-life and controlled asthma. Adolescents with more positive outcome expectations were significantly more likely to have controlled asthma. Being Native American was associated with worse quality-of-life and asthma not being controlled. Being Black was associated with asthma not being controlled. CONCLUSIONS: Parents and providers should work to improve adolescent self-efficacy in managing their asthma because it is associated with asthma responsibility, asthma control, and quality-of-life. Providers need to especially work with Native American and Black adolescents to improve quality-of-life and asthma control.
