BACKGROUND: The proliferation of electronic cigarettes (e-cigarettes) has presented new challenges in public health, particularly among adolescents and young adults. While marketed as safer than tobacco and as cessation aids, e-cigarettes have raised concerns about their long-term health and psychosocial impacts, including potential links to increased suicidal behaviors. This study aims to evaluate the relationship between e-cigarette use and suicidal behaviors by conducting a systematic review of the current literature.
METHODS: We searched PubMed, Web of Science, and EMBASE for studies up to March 10, 2024, examining the relationship between e-cigarette use and suicidal behaviors. Eligible studies included cross-sectional, longitudinal, retrospective, prospective, and case-control designs. Meta-analysis was performed to calculate pooled odds ratios (ORs). Newcastle Ottawa scale was used to assess the quality of studies. R software (V 4.3) was used to perform the meta-analysis.
RESULTS: Our analysis included fourteen studies, predominantly from the US and Korea, with participants ranging from 1,151 to 255,887. The meta-analysis identified a significant association between e-cigarette use and an increased risk of suicidal ideation (OR = 1.489, 95% CI: 1.357 to 1.621), suicide attempts (OR = 2.497, 95% CI: 1.999 to 3.996), and suicidal planning (OR = 2.310, 95% CI: 1.810 to 2.810). Heterogeneity was noted among the studies.
CONCLUSIONS: E-cigarette use is significantly associated with the risk of suicidal behaviors, particularly among adolescents. The findings underscore the necessity for caution in endorsing e-cigarettes as a safer smoking alternative and call for more extensive research to understand the underlying mechanisms. Public health strategies should be developed to address and mitigate the risks of suicidal behaviors among e-cigarette users.

OBJECTIVE: Montelukast is used extensively in children and adolescents for allergic rhinitis and asthma. However, concerns have been raised regarding the increased risk of neuropsychiatric adverse events (NPAEs) associated with montelukast use. Therefore, our case-crossover study was conducted to observe whether there is an increased risk of NPAEs associated with montelukast use in children and adolescents.
METHODS: A population-based case-crossover study using the customised Health Insurance Review and Assessment (HIRA) dataset was conducted. Paediatric patients aged between 0 and 19 years diagnosed with allergic rhinitis and/or asthma with a history of at least one montelukast prescription between 1 January 2018 and 31 December 2021 were included. Exposure to montelukast was assessed during 3-, 7-, 14-, 28- and 56-day hazard periods prior to each patient\'s NPAE. Stratified analyses according to age group, gender and season for the risk of NPAEs associated with montelukast use in the previous 7 days and 14 days were performed, respectively. Conditional logistic regression analysis was used to calculate adjusted ORs (aORs) with their corresponding 95% CIs, adjusting for concomitant medications.
RESULTS: A total of 161 386 paediatric patients was identified. An increased risk of NPAEs associated with montelukast was found in all time window periods, including 3-day (aOR 1.28, 95% CI 1.24 to 1.32), 7-day (aOR 1.29, 95% CI 1.26 to 1.33), 14-day (aOR 1.34, 95% CI 1.31 to 1.37), 28-day (aOR 1.38, 95% CI 1.36 to 1.41) and 56-day (aOR 1.21, 95% CI 1.19 to 1.22) preceding hazard periods compared with use in the four control periods.
CONCLUSIONS: Children and adolescents with allergic rhinitis and/or asthma should be prescribed montelukast with caution considering clinical benefits.

UNASSIGNED: In recent years, the suicide rate among adolescents in China has shown a continuous upward trend, and mental health issues such as depression and excessive anxiety have become increasingly prominent. Awareness and concerns around poor mental health in adolescents is rising among the general public and in academic circles, but there is little research on adolescent mental health policies in China.
UNASSIGNED: This article reviews the national policies on adolescent mental health from 2000 to 2023, and analyzes and evaluates the selected policy texts through the PMC index model.
UNASSIGNED: The study indicates growing national attention towards adolescent mental health policies in terms of both quantity and quality, with improved policy feasibility and synergy. However, shortcomings exist in the policy formulation process, including a lack of advocacy and supervision-oriented policies, a focus on short to medium-term effects, and inadequate comprehensive planning, hindering their swift implementation.
UNASSIGNED: In conclusion, facing the escalating crisis of adolescent mental health, the previous requirements of the education system are no longer sufficient. The government needs to further improve the top-down policy system, weave a safety net for mental health education and preventive intervention, and effectively promote the development of adolescent mental health.

UNASSIGNED: This study evaluated the moderating effects of socioeconomic status (SES) and geographical location on the efficacy of an eHealth school-based multiple health behaviour change intervention - Health4Life - in targeting alcohol and tobacco use, dietary intake, knowledge, behavioural intentions, and psychological distress over 24-months.
UNASSIGNED: Data from the Health4Life cluster-randomised controlled trial conducted from 2019 to 2021 in 71 Australian secondary schools were analysed (N=6639; baseline age 11-14yrs). Schools were from metropolitan (89%) and regional (11%) areas, and participants\' SES was classified as low (15%), mid (37%), and high (48%) relative to the study population. Primary outcomes included alcohol and tobacco use, and a composite indicator of poor diet. Secondary outcomes were knowledge, behavioural intentions, and psychological distress. Latent growth models assessed moderating effects of SES and geographical location on between-group change over 24-months.
UNASSIGNED: Geographical location moderated the intervention\'s effect on odds of reporting a poor diet (OR = 1.79, 95% CI = 1.32-2.43, p < 0.001) and diet-related behavioural intentions (OR = 0.71, 95% CI = 0.56-0.89, p = 0.024) over time. Subset analyses indicated that intervention participants in regional areas had higher odds of reporting a poor diet (OR = 1.61, 95% CI = 1.13-2.29, p = 0.008), while those in metropolitan areas had higher odds of improving diet-related behavioural intentions (OR = 1.13, 95% CI = 1.01-1.27, p = 0.041), compared to the control group. No other significant moderation effects were observed.
UNASSIGNED: While significant disparities were generally not observed, the geographical differences in intervention effects on diet and diet-related intentions suggest that co-designed and tailored approaches may benefit disadvantaged adolescents to address the disproportionately high rates of lifestyle risk behaviours among these priority populations.

Despite improvements in the awareness and acceptance of lesbian, gay, bisexual, transgender, queer, and other sexual and gender diverse (LGBTQ+) individuals, the LGBTQ+ community continues to experience discrimination, which can result in adverse health outcomes. In particular, LGBTQ+ youth have an increased risk of experiencing depression, substance abuse, and suicide. Societal stigma and rejection, bullying, and familial disapproval all contribute to these health disparities. In recognition of these inequities, an interprofessional team of biomedical faculty members, staff, and trainees from the Louisiana State University Health Science Center (LSUHSC) in New Orleans developed the needs-assessment evaluation, the Gender and Sexual Minority Youth Outreach Survey (GSMYO) for high school students. Health science centers have access to resources and experienced personnel who can provide support and education to high school students, teachers, and administrative staff. However, it is important to first determine the high schools\' specific needs, attitudes towards LGBTQ+ acceptance, and their current resources. Faculty, staff, and trainees from the LSUHSC Science Youth Initiative (SYI) and the LSUHSC LGBTQ+ Organization, Tiger Pride, administered the short, anonymous survey to adolescents attending Southeast Louisiana high schools. English Language Learner (ELL) students received the survey in Spanish. Results from the GSMYO needs-assessment survey are presented. Other health science centers may adapt the presented survey to develop needs-based LGBTQ+ high school programs to address the educational and health inequities in their own communities, regardless of location or demographic region.

UNASSIGNED: Although menstruation is a monthly biological phenomenon, it is shrouded in stigma and shame which directly impacts health, education, gender equality, decent work, and economic growth. However, there is scarce evidence on how personal agency, an individual\'s ability to access resources, may act as a protective factor to adequate menstrual health and hygiene practices. Therefore, we assess the association between attitudes toward menstruation and personal agency among very young adolescent girls.
UNASSIGNED: We use cross-sectional data from the Global Early Adolescent Study in São Paulo, Brazil, among 10- to 14-year-old girls who have experienced menarche (n = 325) and completed a home-based self-administered questionnaire in 2021. \"Attitudes toward menstruation\" was created based on five indicators on a Likert scale, with a higher score indicating more positive attitudes. The main covariate was personal agency, comprised of three scales and modeled as three continuous variables: voice, decision-making power, and freedom of movement. Data were analyzed using multivariable linear regression.
UNASSIGNED: Attitudes toward menstruation mean score was 12.5 (range 5-19). Older adolescents (12-14 years-old) had higher mean scores (more positive) than younger adolescents (10-11 years-old) on attitudes toward menstruation, whereas no other sociodemographic or menstrual health indicator (knowledge or access to products) were associated with attitudes toward menstruation. In the multiple regression model, older age and higher freedom of movement remained positively associated with attitudes toward menstruation (βadjust = 0.5; 95%CI 0.1 to 0.8).
UNASSIGNED: Positive attitudes toward menstruation are associated with higher freedom of movement among very young Brazilian adolescent girls. The promotion of personal agency should be recognized as key strategies to accelerate young girls\' positive approaches to their own menstruation and, consequently, well-being.
Menstrual Health and Hygiene Attitudes are associated with Personal AgencyOur results show that positive attitudes toward menstruation among very young adolescent girls are associated with personal agency, measured through freedom of movement. This information can inform strategies to accelerate young girls’ positive approaches to their own menstruation and, consequently, well-being.

OBJECTIVE: Estimating children\'s target height (TH) plays an important role in diagnosing, evaluating and treating many paediatric endocrinological diseases. However, in many countries, employing Tanner\'s formula to predict children\'s final adult height (FAH) is considered misleading. Therefore, this study aimed to re-evaluate the validity of Tanner\'s formula for predicting the TH of Korean adolescents and young adults and develop a new formula suitable for Korean children.
METHODS: Data were derived from the Korean National Health and Nutrition Examination Survey 2010-2019.
METHODS: A total of 2586 participants (1266 men, 1320 women) were included, excluding participants for whom Tanner\'s formula could not be calculated because of missing parental height data.
METHODS: Tanner-based TH was compared with the FAH.
RESULTS: The difference between Tanner-based TH and FAH was 4.86±0.178 cm for men and 4.81±0.150 cm for women. Sex-specific univariable and multivariable analyses were conducted to determine variables influencing positive height gap (greater than estimated TH). Both men and women with higher education levels were more likely to exhibit a positive height gap. Those with a history of chronic illness were less likely to exhibit a positive height gap, particularly in women. Using a new formula derived using linear regression analysis, the sum of parental heights explained 27.6% and 30.6% of the variance in sons\' and daughters\' heights, respectively.
CONCLUSIONS: Tanner\'s formula for calculating TH tended to underestimate FAH; hence, our new formula may offer a better alternative for estimating TH and evaluating growth in Korean children and adolescents.

OBJECTIVE: Emerging research evidence suggests positive relationships between higher screen time and eating disorders. However, few studies have examined the prospective associations between screen use and eating disorder symptoms in early adolescents and how problematic screen use may contribute to symptom development.
METHODS: We analyzed prospective cohort data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 10,246, 2016-2020, ages 9-14). Logistic regression analyses were used to estimate the longitudinal associations between baseline self-reported screen time and eating disorder symptoms in year two. Logistic regression analyses were also used to estimate cross-sectional associations between problematic screen use in year two (either problematic social media or mobile phone use) and eating disorder symptoms in year two. Eating disorder symptoms based on the Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS-5) included fear of weight gain, self-worth tied to weight, engaging in compensatory behaviors, binge eating, and distress with binge eating.
RESULTS: Each additional hour of total screen time and social media use was associated with higher odds of fear of weight gain, self-worth tied to weight, compensatory behaviors to prevent weight gain, binge eating, and distress with binge eating two years later (odds ratio [OR] 1.05-1.55). Both problematic social media and mobile phone use were associated with higher odds of all eating disorder symptoms (OR 1.26-1.82).
CONCLUSIONS: Findings suggest greater total screen time, social media use, and problematic screen use are associated with more eating disorder symptoms in early adolescence. Clinicians should consider assessing for problem screen use and, when high, screen for disordered eating.
METHODS: Level III: Evidence obtained from well-designed cohort or case-control analytic studies.

UNASSIGNED: Anaemia is one leading cause of morbidity among adolescent girls. Prevention, early detection, and treatment can break the intergeneration cycle of malnutrition.
UNASSIGNED: The aim of the study was to estimate the prevalence of anaemia and assess its sociodemographic determinants and understand its association with the dietary pattern of rural adolescent girls.
UNASSIGNED: A cross-sectional study was conducted among 350 adolescent girls studying in the school of Kalgatigi Taluk, Dharwad district. The school girls were interviewed using a predesigned structured questionnaire by interview method. A food frequency questionnaire was used to assess the dietary pattern. Haemoglobin levels were estimated using Sahli\'s method.
UNASSIGNED: Data were entered in Microsoft Excel and analysed using SPSS version 19 and the Chi-square test was applied to study the significance.
UNASSIGNED: Rural adolescent school girls between the age group of 13-16 years were included. The prevalence of anaemia among them was found to be 47.4% and was significantly associated with the educational status of the mother, their socioeconomic status (SES), and type of diet. Vegetarian girls had a higher prevalence of anaemia. The frequency of meat and egg consumption was significantly associated with anaemia. The prevalence of anaemia was higher in thin and severely thin girls based on WHO-BMI.
UNASSIGNED: Anaemia in rural adolescent girls is of high burden and public health importance with a prevalence of 47.4% and significant association with dietary habits, SES, and BMI.
