Sleep Problems Among Black Youth Exposed to Police Violence on Digital Media.

Findings from a recent survey of a community-based sample of Black youth ages 12 through 21 in Baltimore City, Maryland (n = 345) reveal that viewing fatal police violence videos is associated with significant increases in the odds of youth sleep disturbances, and about 30% of this association is attributable to emotional distress after viewing the videos.

Adverse Childhood Experiences and Trajectories of Firearm Exposure in Childhood.

OBJECTIVE: To examine the longitudinal relationship between exposure to adverse childhood experiences (ACEs) in early life and trajectories of firearm exposure from early to middle childhood (ages 5-9 years old). STUDY DESIGN: Data from the Longitudinal Studies of Child Abuse and Neglect (LOGSCAN) study were used. The LONGSCAN study was a prospective study in the United States and contained data from 1354 children from age 4 to age 18 years old. Exposure to ACEs was measured through the wave 1 interview (age 5 years old) and trajectories of firearm exposure were created using data from waves 1 (age 5 years old) and two (age 9 years old). RESULTS: Two trajectories of firearm exposure in childhood were identified: a low exposure group and a group with persistently-high firearm exposure from ages 5 to 9 years old. ACEs were associated with membership in the high exposure group and children with four or more ACEs had over twice the odds of membership in the high exposure group compared with children with zero ACEs. CONCLUSION: ACEs exposure in early childhood is associated with persistently-high exposure to firearms from early to middle childhood. This finding highlights the need for pediatricians to consider screening for both ACEs and firearm exposure in routine examinations, as well as the need for future research to identify and evaluate interventions intended to address exposure to adversity and firearms.

Associations between media parenting practices and early adolescent screen use.

BACKGROUND: To assess the prevalence of various media parenting practices and identify their associations with early adolescent screen time and problematic social media, video game, and mobile phone use. METHODS: Cross-sectional data from Year 3 of the Adolescent Brain Cognitive Development (ABCD) Study (2019-2022) that included 10,048 adolescents (12-13 years, 48.3% female, 45.6% racial/ethnic minorities) in the US were analyzed using multiple linear regression analyses adjusting for potential confounders. RESULTS: Parent screen use, family mealtime screen use, and bedroom screen use were associated with greater adolescent screen time and problematic social media, video game, and mobile phone use. Parental use of screens to control behavior (e.g., as a reward or punishment) was associated with higher screen time and greater problematic video game use. Parental monitoring of screens was associated with lower screen time and less problematic social media and mobile phone use. Parental limit setting of screens was associated with lower screen time and less problematic social media, video game, and mobile phone use. DISCUSSION: Parent screen use, mealtime screen use, and bedroom screen use were associated with higher adolescent problematic screen use and could be limited in a family media use plan. Parental monitoring and limiting of screen time are associated with less problematic screen use. IMPACT STATEMENT: Although the American Academy of Pediatrics provides guidance for screen use for children 5-18 years, there is a paucity of evidence-based guidance for media parenting practices, specifically for early adolescents. In a diverse sample of 10,048 early adolescents across the US, we found cross-sectional associations between parent, mealtime, and bedroom screen use and higher adolescent problematic screen use. Parental monitoring and limiting of adolescent screen time were cross-sectionally associated with less problematic screen use in our analytic sample and may be incorporated into a family media use plan.

Cumulative Police Exposures, Police Violence Stress, and Depressive Symptoms: A Focus on Black LGBQ Youth in Baltimore City, Maryland.

The present study investigates associations between cumulative police exposures, police violence stress, and depressive symptoms among Black youth, and whether LGBQ (lesbian, gay, bisexual, and queer) identities moderate these associations. Data come from the Survey of Police-Adolescent Contact Experiences (SPACE), a cross-sectional survey of a community-based sample of Black youth ages 12-21 in Baltimore City, Maryland (n = 345), administered from August 2022 to July 2023. We used multivariable ordinary least squares regression to estimate direct associations and product-term analysis to test for effect modification by sexual identities. We also calculate covariate-adjusted predicted depressive symptoms scores by cumulative police exposures and police violence stress across sexual identities. Findings indicate that LGBQ youth collectively reported higher levels of police violence stress than heterosexual youth. Still, LGBQ youth varied in their cumulative police exposures, which were significantly higher among bisexual and queer youth than lesbian or gay youth. Associations between cumulative police exposures, police violence stress, and depressive symptoms were significantly moderated by LGBQ identity, with the largest associations emerging for bisexual and queer youth. Police exposures and police violence stress also compounded to worsen depressive symptoms among the subsample of LGBQ youth. Collectively, our findings suggest that LGBQ youth-especially bisexual and queer youth-may be particularly vulnerable to the mental health harms of cumulative police exposures and police violence stress. Intersectional, public health approaches that combine prevention and treatment strategies are needed to mitigate LGBQ mental health inequities stemming from cumulative police exposures and police violence stress.

Prospective association of screen time with binge-eating disorder among adolescents in the United States: The mediating role of depression.

OBJECTIVE: Screen time has been reported to be associated with binge-eating disorder (BED) among adolescents in the US; however, potential mediators remain unclear. This study aimed to evaluate depression symptoms as a mediator of the prospective association between screen time and BED. METHOD: We utilized data from 9465 children (aged 9-11 years at baseline) from the Adolescent Brain Cognitive Development (ABCD) study (2016-2021). A generalized structural equation model was used to examine the prospective association between average daily screen time at baseline and BED at year 2, adjusting for baseline BED diagnosis, and other potential covariates (e.g., age, sex, and income). Mediation was examined using bias-corrected (BC) 95% confidence intervals for the indirect effect of baseline screen time on year 2 BED through depression symptoms (change from baseline to year 1). RESULTS: One hundred and one participants (42.7% male, 49.4% racial/ethnic minority) met the criteria for BED in year 2. Participants were 9.9 years of age on average at baseline, 51.3% identified as male, and 43.1% identified as a racial/ethnic minority. Adjusting for covariates, screen time was prospectively associated with BED (OR = 1.09, 95% CI [1.03, 1.14], p = .005). Depression symptoms (B = .19, BC 95% CI [0.10, 0.28]) partially mediated (9.2%) the prospective association between screen time and BED. DISCUSSION: Among US adolescents, higher baseline screen time was prospectively associated with BED diagnosis at year 2, and this relationship was partially mediated by increased depression symptoms. Preventive approaches targeting high screen use may have utility for reducing BED risk among adolescents. PUBLIC SIGNIFICANCE: Among U.S. adolescents, higher screen time was prospectively associated with the incidence of BED. This association was partially mediated by the change in depressive symptoms. Preventive approaches targeting high screen use may have utility for reducing BED risk among adolescents.

Sex Work and Educational Mobility: Results from the National Longitudinal Study of Adolescent to Adult Health.

The purpose of the study was to assess the relationship between sex work involvement and education mobility among a national sample of US young adults. Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health; N = 7732) were analyzed to explore the prospective association between lifetime sex work involvement measured in young adulthood (Wave III; ages 18-26) and educational mobility measured in adulthood (Wave V; ages 33-43). Multinomial logistic regression analyses were conducted, adjusting for relevant demographic and control variables. Results indicated that young adults who reported ever having been paid for sex by the ages of 18-26 had twofold greater risk (95% confidence interval 1.26-3.18) of having downward educational mobility compared to a stable level of education, or the same education, relative to their parents in adulthood. Given that education, by means of regular social connectedness to social supports, may be the most salient resiliency factor protecting adolescents from potential risks associated with sex work involvement (e.g., stigma, isolation from services), the findings from this study support the promotion of inclusive engagement from school settings to foster educational attainment and prevent poorer health and psychosocial outcomes that research to date has associated with sex work involvement.

Adverse childhood experiences and unhealthy dietary behaviours in adulthood.

OBJECTIVE: This study assesses the relationship between adverse childhood experiences (ACE) occurring before the age of 18 years and patterns of fast-food consumption and sugary beverage consumption in adulthood. The study also examines how perceived stress and socio-economic status (SES) (college educational attainment and income) in adulthood mediate this relationship. DESIGN: Using data from the National Longitudinal Study of Adolescent to Adulthood Health (N 8599), multinomial logistic regression analyses were carried out to assess the association between ACE and unhealthy dietary behaviours in adulthood. Karlson-Holm-Breen mediation analysis is used to determine the mediating effects of SES and perceived stress. SETTING: Persons living in the USA in 2016-2018. PARTICIPANTS: Adults (n 8599) aged 33-44 years. RESULTS: The findings show an association between four or more ACE and high fast-food (relative risk ratio (RRR) = 1·436, 95 % CI = 1·040, 1·983) and high sugary beverage consumption (RRR = 1·435, 95 % CI = 1·002, 2·055). The association between ACE and high fast-food consumption is partially mediated by college educational attainment, and the association between ACE and high sugary beverage consumption is partially mediated by perceived stress and college educational attainment. CONCLUSIONS: ACE can have long-term consequences for unhealthy dietary behaviours in adulthood, and this relationship is partially due to a lower likelihood of higher perceived stress and college educational attainment among ACE-exposed persons. Future research is needed to understand further the influence of ACE on dietary patterns over the life course.

Association of physical activity and screen time with cardiovascular disease risk in the Adolescent Brain Cognitive Development Study.

BACKGROUND: According to the Physical Activity Guidelines Advisory Committee Scientific Report, limited evidence is available on sedentary behaviors (screen time) and their joint associations with physical activity (steps) for cardiovascular health in adolescence. The objective of this study was to identify joint associations of screen time and physical activity categories with cardiovascular disease (CVD) risk factors (blood pressure, hemoglobin A1c, cholesterol) in adolescence. METHODS: This study analyzed data from the Adolescent Brain Cognitive Development (ABCD) Study, comprising a diverse sample of 4,718 U.S. adolescents aged 10-15 years between 2018 and 2021. Steps were measured by a Fitbit wearable device and levels were categorized as low (1,000-6,000), medium (> 6,000-12,000), and high (> 12,000) averaged daily step counts. Self-reported recreational screen time hours per day were classified as low (0-4), medium (> 4-8), and high (> 8) hours per day. CVD risk factors including blood pressure, hemoglobin A1c, and cholesterol (total and HDL) were measured. RESULTS: The analytical sample averaged 6.6 h of screen time per day and 9,722 steps per day. In models including both screen time and steps, the high screen time category was associated with a 4.27 higher diastolic blood pressure percentile (95% CI 1.83-6.73) and lower HDL cholesterol (B= -2.85, 95% CI -4.77 to -0.94 mg/dL) compared to the low screen time category. Medium (B = 3.68, 95% CI 1.24-6.11) and low (B = 7.64, 95% CI 4.07-11.20) step categories were associated with higher diastolic blood pressure percentile compared to the high step category. The medium step category was associated with lower HDL cholesterol (B= -1.99, 95% CI -3.80 to -0.19 mg/dL) compared to the high step category. Findings were similar when screen time and step counts were analyzed as continuous variables; higher continuous step count was additionally associated with lower total cholesterol (mg/dL). CONCLUSIONS: Combinations of low screen time and high steps were generally associated with favorable cardiovascular health markers including lower diastolic blood pressure and higher HDL cholesterol, which can inform future adolescent health guidelines.

Association of body mass index with progression from binge-eating behavior into binge-eating disorder among adolescents in the United States: A prospective analysis of pooled data.

The association between body mass index (BMI) and binge-eating disorder (BED) is well-established. However, data on the extent to which BMI is associated with progression from binge-eating behavior into BED among adolescents are limited, which was the aim of this investigation. Participants were 9964 U.S. adolescents from the Adolescent Brain Cognitive Development (ABCD) Study, aged 9-13 at the time of study enrollment. A computerized parent-reported assessment was used to establish adolescents' binge-eating behaviors and BED. Cox proportional hazards models adjusting for sociodemographic covariates were used to examine prospective associations between BMI and likelihood of BED onset among a) adolescents with binge-eating behavior, and b) adolescents with no binge-eating behavior. Of 975 adolescents who met the study criteria for binge-eating behavior, 89 (9.1%) subsequently met the study criteria for BED. Of 8989 adolescents with no binge-eating behavior, 82 (0.9%) subsequently met the study criteria for BED. BMI percentile was significantly associated with the likelihood of BED onset in participants with (adjusted HR = 1.03, 95% confidence interval [CI] 1.00, 1.06) and participants without (adjusted HR = 1.05, 95% CI 1.03, 1.07) binge-eating behavior. Results were also significant when examining BMI as a dichotomous predictor (above and below 85th percentile) among those with (adjusted HR = 2.60, 95% CI 1.00, 6.68) and those without (adjusted HR = 6.01, 95% CI 3.90, 11.10) binge-eating behavior. Overall, results indicate that elevated BMI is prospectively associated with a greater risk for BED onset among U.S. adolescents with or without binge-eating behavior. Adolescents with a higher BMI may benefit from screening for binge eating, and prevention/early intervention strategies to mitigate the risk for developing BED.

Lower Perceived Neighborhood Collective Efficacy Indirectly Influences the Association Between Perceived Maternal Exposure to Community Violence and Household Food Insecurity.

BACKGROUND AND OBJECTIVES: Individuals of color and of low socioeconomic status are at greater risk of experiencing community violence and food insecurity, which are both influenced by neighborhood conditions. We evaluated neighborhood collective efficacy as a linkage between community violence exposure and household food insecurity. METHODS: Mothers from the Future of Families and Child Wellbeing Study who completed phone surveys when the child was 3 (time 1, T1) and 5 years old (time 2, T2) were included (n = 2068). A covariate-adjusted structural equation model estimated direct and indirect effects of community violence exposure on household food insecurity. A covariate-adjusted multiple mediator model estimated the indirect effects of the 2 neighborhood collective efficacy subscales (informal social control; social cohesion and trust). RESULTS: At T1, 40% of mothers reported community violence exposure; 15% experienced food insecurity at T2. Mean neighborhood collective efficacy (range 1-5) at T1 was 2.44 (SD = 0.94). Neighborhood collective efficacy indirectly influenced the association between community violence exposure and food insecurity (indirect effect = 0.022, 95% CI = 0.007 to 0.040). Only social cohesion and trust contributed independent variance to the indirect effect model (indirect effect = 0.028, 95% CI = 0.001 to 0.056). CONCLUSIONS: Community-based efforts to reduce household food insecurity should emphasize building social cohesion and trust in communities experiencing violence.

Police Contact, Non-Suicidal Self-Injury, and Suicidal Ideation: Findings From a National Sample of Canadian Adolescents and Young Adults.

BACKGROUND AND OBJECTIVES: The purpose of this research is to investigate associations between police contact, non-suicidal self-injury (NSSI), and suicidal ideation (SI) among a national sample of Canadian adolescents and young adults (ages 16-30). METHODS: Data used in this study were obtained from the Canadian Study of Adolescent Health Behaviors (N = 940), a national survey of Canadians ages 16-30. RESULTS: Police contact was associated with higher odds of NSSI (OR = 1.98, 95% CI = 1.37, 2.86). Those who reported police contact with intrusion (OR = 2.39, 95% CI = 1.49, 3.38) and police contact with harassment (OR = 3.98, 95% CI = 2.30, 6.88) had higher odds of NSSI relative to respondents with no contact. Finally, any police contact was associated with higher odds of SI (OR = 1.56, 95% CI = 1.04, 2.34) and respondents experiencing police stops with harassment had higher odds of SI compared to those who had never been stopped (OR = 2.48, 95% CI = 1.45, 4.24). CONCLUSIONS: Distressing police contact heightens the risk of NSSI and SI among young people. Rigorous evaluation of trauma-informed, developmentally appropriate strategies for identifying and intervening on NSSI and SI following adverse police encounters should be prioritized.

Associations between receiving non-consensual image and video sexts and average sleep duration among adolescents and young adults.

Background Sexting is the sending and receiving of nude or partially nude images or videos. Despite it being a part of contemporary relationships, it can have adverse effects. This is particularly the case when receiving non-consensual sexts. To date, there remains a gap in the literature on whether receiving non-consensual sexts is associated with poor sleep. Therefore, the aim of this study was to determine the association between receiving non-consensual sexts and average sleep duration. Methods Data from Wave 2 (2022) of the Canadian Study of Adolescent Health Behaviours (N =906) were analysed. Multinomial logistic regression analyses were used to determine the association between receiving non-consensual sexts (both image and video) in the past 12months and average sleep duration (≤5h, 6h, 7h, 8h, and ≥9h) in the past 2weeks. Analyses were stratified by gender. Results Girls and women who received non-consensual image and video sexts, compared to those who did not, were more likely to report ≤5h of average sleep in the past 2weeks, relative to 8h of average sleep. There were no significant findings among boys and men. Conclusion Findings underscore that receiving non-consensual image and video sexts may negatively impact sleep among girls and women, which may be contextualised by trauma responses experienced because of gender-based sexual violence. Healthcare and mental health professionals should be made aware of this association to provide effective care to girls and women.

Social Media Use and Alcohol Sipping in Early Adolescents: A Prospective Cohort Study.

BACKGROUND: Social media can influence alcohol initiation behaviors such as sipping, which can lead to future adverse alcohol-related outcomes. Few studies have examined the role of problematic social media use, characterized by addiction, mood modification, tolerance, withdrawal, conflict, and relapse, especially in early adolescence. OBJECTIVE: To examine the prospective association between social media use and sipping alcohol in a nationwide sample of early adolescents, and the extent to which problematic social media use mediates the association. METHODS: We analyzed prospective data from the Adolescent Brain Cognitive Development Study (N = 7514; ages 9-10 years at baseline; 2016-2018) to estimate associations between social media time (Year 1) and alcohol sipping (Year 3) using modified Poisson regression, adjusting for confounders and testing problematic social media use (Year 2) as a mediator. RESULTS: Social media time (Year 1) was prospectively associated with 1.31 (95% confidence interval 1.20-1.43) times higher risk of new-onset sipping (Year 3). The association between social media time and new-onset alcohol sipping was partially mediated by problematic social media use at Year 2 (25.0% reduction in the association between the former two factors after adding problematic social media use, p = 0.002). CONCLUSIONS: Time spent on social media was associated with a higher risk of alcohol sipping in a diverse national sample of early adolescents, and the association was partially mediated by problematic social media use. Media literacy education and family media use plans could advise early adolescents about exposure to alcohol content on social media and warning signs for problematic use.

Depression among incarcerated persons following the death of a loved one: Does social support mitigate grief?

The death of a loved one generates adverse and potentially damaging consequences for surviving family members and friends. The challenges of bereavement can be especially severe when experienced by incarcerated persons who must cope with and grieve the death while incarcerated. Yet, limited research evaluates bereavement among incarcerated persons and whether factors such as social support buffer against health-related consequences. Using data from the LoneStar Project-a study of 802 incarcerated men in Texas-we examine depressive symptoms among currently incarcerated persons with differential exposure to a loved one's death (i.e., immediate family, friends, extended family). Importantly, a high rate of death exists among incarcerated persons' loved ones, with 41% in the sample losing someone on the outside during their final year of incarceration. However, we find that external social support from family and friends and in-prison social cohesion from peers, significantly mitigate the harms of bereavement on depressive symptoms.

Exploration of the effects of incarceration on the health of Latina women and their children using the life course theory.

OBJECTIVE: Use the Life Course Theory (LCT) to explore the effects of involvement with the justice system on the health of Latina women and their children. DESIGN: A supplementary analysis was conducted using data collected from the original study to answer a new research question. SETTING: South Central Texas. PARTICIPANTS: A primary qualitative data set from 12 Latina women involved with the justice system. METHODS: We applied LCT principles and used thematic content analysis as such we employed categoric distinction: lifespan development, time and place in individuals' lives, the timing of lives, human agency, and linked lives to analyze participants' narratives. RESULTS: Five themes emerged that aligned with LCT principles: (1) It feels like I'm living in my own prison; (2) What do I have to live for now; (3) It is like double punishment; (4) They made my choices; and (5) People didn't really understand. Participants felt helpless with few options to overcome their prior adversities, which affected their ability to make positive future choices. CONCLUSIONS: Findings highlight the potential, long-term, negative health consequences that may result from incarceration. Considering that justice system involvement can lead to more profound maternal and child health disparities, our findings suggest that greater advocacy from the nursing profession would increase accessibility to equitable and respectful maternity and women's health care services. Key points Involvement with the justice system can result in negative health consequences for women and their children. Maternal and child health disparities are often more profound after involvement with the justice system. Greater advocacy is needed from the nursing profession to ensure access to equitable and respectful maternity and women's health care services.

The Association Between Adverse Childhood Experiences (ACEs), Bullying Victimization, and Internalizing and Externalizing Problems Among Early Adolescents: Examining Cumulative and Interactive Associations.

Both adverse childhood experiences (ACEs) and bullying victimization are linked with mental health problems in adolescents. However, little is known about the overlap between the two factors and how this impacts adolescent mental health problems (i.e., internalizing and externalizing problems). The current study analyzed data from 8,085 participants (47.7% female; 44.1% racial/ethnic minority) in the Adolescent Brain Cognitive Development (ABCD) study, baseline (2016-2018, ages 9-10 years) to Year 2. Regression analyses were used to estimate associations between ACEs, bullying victimization and mental health problems, respectively, adjusting for sex, race/ethnicity, country of birth, household income, parental education, and study site. The findings showed that both ACEs and bullying victimization were independently associated with higher internalizing and higher externalizing problems. However, no significant interaction was found between ACEs and bullying victimization. Overall, the results align with the cumulative risk model of adversity, linking cumulative ACEs and bullying victimization to internalizing and externalizing problems in early adolescents.

Positive Early Childhood Experiences and School Readiness among US Preschoolers.

OBJECTIVES: To characterize the relationship between positive early childhood experiences (PECEs) and school readiness, and assess whether the PECEs-school readiness relationship was robust to and/or differed across levels of adverse childhood experiences (ACEs). METHODS: We analyzed national data on children ages 3-5 from 2016 to 2020 (n = 26 871) to examine associations between key PECE domains (nurturing relationships, home learning opportunities, safe and stable environments, and family routines) with being on track for school readiness, defined using a pilot, multidimensional measure called "healthy and ready to learn". Weighted univariate, bivariate, and multivariable analyses were conducted to generate nationally representative estimates. Multivariable models adjusted for sociodemographic factors and were assessed both with and without cumulative ACE exposure. RESULTS: Two-fifths of children were healthy and ready to learn. Exposure to PECEs was associated with higher school readiness, irrespective of relative ACE exposure. Compared with those with low PECEs, children with moderate (aOR, 2.19; 95% CI, 1.86-2.58) and high (aOR, 4.37; 95% CI, 3.58-5.34) PECEs had greater odds for being healthy and ready to learn, net of both sociodemographic factors and ACE exposure. Significant associations were robust across demographic groups (eg, race and ethnicity), ACE levels, and ACE types (eg, parental incarceration). CONCLUSIONS: Increasing PECEs correspond with greater likelihood of possessing capacities key for school functioning, even amidst ACEs. In concert with efforts to ameliorate early life trauma, caregivers, health care providers, educators, and systems can consider boosting PECEs to foster healthy development in childhood and beyond.

Screen Time from Adolescence to Adulthood and Cardiometabolic Disease: a Prospective Cohort Study.

BACKGROUND: Previous studies have analyzed the relationship between screen time and cardiometabolic disease risk factors among adolescents, but few have examined the longitudinal effects of screen time on cardiometabolic health into adulthood using nationally representative data. OBJECTIVE: To determine prospective associations between screen time and later cardiometabolic disease over a 24-year period using a nationally representative adolescent cohort. DESIGN: Longitudinal prospective cohort data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) collected from 1994 to 2018. PARTICIPANTS: Adolescents aged 11-18 years old at baseline (1994-1995) followed for 24 years. MAIN MEASURES: Predictors: screen time (five repeated measures of self-reported television and video watching from adolescence to adulthood). OUTCOMES: Five repeated measures of body mass index (BMI); two repeated measures of waist circumference, hypertension, hyperlipidemia, and diabetes collected at 15- and 24-year follow-up exams. KEY RESULTS: For the 7105 adolescents in the sample (49.7% female, 35.0% non-white), the baseline adolescent average screen time per day was 2.86 ± 0.08 hours per day, which generally declined through 24-year follow-up. Average BMI at baseline was 22.57 ± 0.13 kg/m2, which increased to 30.27 ± 0.18 kg/m2 through follow-up. By 24-year follow-up, 43.4% of participants had obesity, 8.4% had diabetes, 31.8% had hypertension, and 14.9% had hyperlipidemia. In mixed-effects generalized linear models, each additional hour of screen time per day was associated with 0.06 (95% CI 0.04-0.09) within-person increase in BMI. Each additional hour of screen time per day was associated with higher within-person odds of high waist circumference (AOR 1.17, 95% CI 1.09-1.26), obesity (AOR 1.09, 95% CI 1.03-1.15), and diabetes (AOR 1.17, 95% CI 1.07-1.28). Screen time was not significantly associated with hypertension or hyperlipidemia. CONCLUSIONS: In this prospective cohort study, higher screen time in adolescence was associated with higher odds of select indicators of cardiometabolic disease in adulthood.

Social epidemiology of the Mediterranean-dietary approaches to stop hypertension intervention for neurodegenerative delay (MIND) diet among early adolescents: the Adolescent Brain Cognitive Development Study.

BACKGROUND: The purpose of our study was to understand the relationship between sociodemographic factors and adherence to the MIND (Mediterranean-DASH [Dietary Approaches to Stop Hypertension] Intervention for Neurodegenerative Delay) diet in a demographically diverse national population-based sample of 9-12-year-olds in the US. METHODS: We analyzed data from the Adolescent Brain and Cognitive Development (ABCD) Study (Year 1, N = 8333). Multivariable linear regression analysis was used to identify associations between MIND diet score and sociodemographic factors, including race/ethnicity, household income, parent education level, age, sex, and sexual minority status. RESULTS: Compared to White adolescents, Latino adolescents showed the greatest adherence to the MIND diet. Boys had lower adherence to the MIND diet than girls. Lower household income was associated with lower adherence to the MIND diet. Older age was associated with lower adherence to the MIND diet. Sexual minorities had a lower adherence to the MIND diet when compared to their heterosexual counterparts. DISCUSSION: Female sex, Latino ethnicity, Asian and Black race, high household income, heterosexual sexual orientation, and younger age were associated with higher adherence to the MIND diet. These sociodemographic differences can inform targeted screening and counseling for clinicians and public health organizations among diverse adolescent populations. IMPACT STATEMENT: Sociodemographic disparities in diet quality have been documented, but none have explored adherence to the MIND (Mediterranean-DASH [Dietary Approaches to Stop Hypertension] Intervention for Neurodegenerative Delay) diet in early adolescence. In this demographically diverse sample of 9-12-year-old early adolescents in the U.S., we found notable and nuanced sociodemographic disparities in adherence to the MIND diet. Sociodemographic factors associated with higher adherence to the MIND diet included female sex, Latino ethnicity, high household income, heterosexual sexual orientation, and younger age.

Screen time, social media use, and weight-change behaviors: Results from an international sample of adolescents.

This study aimed to investigate whether screen time and social media use are associated with weight-change behaviors among an international sample of adolescents. Cross-sectional data from the 2020 International Food Policy Study Youth Survey (ages 10-17; Australia, Canada, Chile, Mexico, United Kingdom, United States; N = 12,031) were analyzed. Self-reported hours of use of five forms of screen time (e.g., social media use), and total screen time per weekday were assessed. Use of six contemporary social media platforms (e.g., Facebook, Instagram) were also assessed. Weight-change behaviors included current attempts to gain weight, lose weight, stay the same weight, and not do anything to change weight, as well as dieting to lose weight in the past 12 months. Greater total screen time per weekday was associated with attempts to gain weight and lose weight, and dieting to lose weight. Specific social media platform use was associated with weight-change behaviors. For example, use of Twitter was most strongly associated with attempts to gain weight, lose weight, and dieting to lose weight. Findings underscore the international pervasiveness of screen time and social media use correlating with weight-change behaviors among adolescents. Global efforts are needed to ensure the appropriate use of screens and social media among adolescents.
