Unhealthy weight control behaviors and health risk behaviors in American youth: a repeated cross-sectional study.

BACKGROUND: Unhealthy weight control behaviors (UWCBs) involve weight control strategies to reduce or maintain weight, such as fasting, taking diet pills, and vomiting or taking laxatives. UWCBs in teenagers can escalate into severe health issues such as eating disorders. Understanding the trends of UWCBs and their association with risk behaviors in teenagers is crucial, as early intervention and prevention strategies are pivotal. METHODS: This study utilized eight waves of the youth risk behavior surveillance system (YRBSS) data from 1999 to 2013. Our primary outcome was UWCBs engagement. We used multinomial logistic models to analyze the association between UWCBs and risk behaviors among adolescents including driving after alcohol consumption, suicide attempts, smoking, alcohol use, and sexual intercourse. RESULTS: Among 109,023 participants, UWCBs prevalence was 16.64%. Body Mass Index (BMI) was significantly associated with UWCBs risk. In addition, we found the intention of weight management confounded the relationship between BMI and UWCBs. The unadjusted logistic regression indicated a monotone-increasing association between BMI and the risk of UWCBs. In contrast, the adjusted logistic regression indicated a U-shaped curve with the lowest (BMI < 17 kg/m2) and highest (BMI > 30 kg/m2) BMI groups having significantly higher odds of engaging in UWCBs compared to the reference BMI group (18.5 ≤ BMI ≤ 24.9 kg/m2). CONCLUSIONS: The intention of weight management confounded the relationship between Body Mass Index (BMI) and the risk of UWCBs. These findings suggest that healthcare interventions for weight management behaviors should be tailored to adolescents with BMI ≥ 25 and BMI < 18.5.

This study looked at unhealthy weight control behaviors (UWCBs) in American teenagers, such as fasting, taking diet pills, or vomiting to control weight. These behaviors can lead to serious health problems, including eating disorders. The research analyzed data from over 100,000 teenagers between 1999 and 2013 to understand the connection between UWCBs and other risky behaviors like drinking alcohol, smoking, and attempting suicide. While previous research suggested that teens with higher body weight were more likely to engage in UWCBs, our findings showed a shift in this relationship after considering the teens' intentions to manage weight. Specifically, teens with very low body weight (BMI < 17) and a strong desire to lose weight had an increased risk of UWCBs. This highlights the need for healthcare providers to focus on the mental health and weight management goals of these teens to prevent harmful behaviors. Additionally, reconsidering the removal of UWCB-related questions from national surveys like YRBSS is important to continue monitoring these behaviors.

Effect of a context-specific health education intervention on knowledge of health risk behaviors among adolescents in Nigerian public and private secondary schools: a comparative study.

OBJECTIVES: Health education programmes that utilizes multicomponent classroom teaching strategies have the potential to enhance knowledge, attitudes, and actions of adolescents concerning health risk behaviors (HRBs). This study assessed the effect of a school-based context-specific health education intervention (CsHEI) on knowledge of HRBs among in-school adolescents in public- and private-owned secondary schools in Nigeria. METHODS: In-school adolescents were recruited into this quasi-experimental study using stratified random sampling from secondary schools in Ile-Ife, Osun-State, Nigeria. Knowledge of HRBs was assessed pre- and post-implementation of a CsHEI. The intervention was a four-week instructor-led health education class on HRBs, delivered over a 2-h class activity per week. Data was summarized using descriptive statistics as well as Inferential statistics. RESULTS: With a mean age of 14.9 ± 1.56 years, a total of 145 females (54.3 %) and 122 males (45.7 %) participated in this study. Over 70 % of the participants had good knowledge of HRBs prior to the intervention with the pre-test mean general knowledge of HRB (t=-3.13, p=0.002) and knowledge of personal safety (t=-2.99, p=0.003) being significantly lower between students in public-schools compared to their private-school counterparts. Post-intervention, a significant improvement in participants' knowledge was observed in all HRB domains with over 90 % of participants having a good knowledge of HRBs. CONCLUSIONS: The CsHEI improved knowledge of in-school adolescents in public- and private-owned secondary schools in Osun state, Nigeria in all domains of HRBs. Integrating the CsHEI with other health behavioral change strategies can mitigate prevalence of HRBs among adolescents, thereby improving health-outcomes and well-being of adolescents.

Exploring the Loss Aversion Scale's psychometric properties in Spain.

Loss aversion is a psychological construct defined as a tendency to value potential losses more than gains in a situation that requires decision-making. The Loss Aversion Scale (LAS, eight items) measures an individual's loss aversion to various situations. However, the generalization of its psychometric properties to different population groups is unknown. This study aimed to validate the LAS instrument for use among Spanish university adults. To this end, two studies were conducted: a content validity study calculating the substantive validity (N = 24) of the instrument's translation from original English to Spanish and a study of internal structure and association (N = 766) among Spanish university men and women aged 18-35. The analyses performed for each sample indicated that the instrument had adequate validity and reliability values as a one-dimensional measure; however, items 5 and 8 had to be removed. Their scores indicated moderate-magnitude correlations with social desirability. This article debates the study's limitations, practical implications, and future lines of research based on the results. The conclusion is that the Loss Aversion Scale instrument suits general Spanish population samples and requires probable methodological control concerning social desirability.

The effects of alcohol sale bans on children: The case of Russia.

Alcohol control policies are implemented to reduce alcoholism and related harms around the globe. This work examines the effects of a policy that restricted when alcohol could be purchased on child outcomes in Russia. To identify causal impacts, I exploit variation in the timing and severity of the restriction, which was implemented in Russian states between 2005 and 2010. Utilizing household survey data and a difference-in-differences estimation approach, I find that the policy has improved children's physical health, with younger children being more affected, and additionally has decreased a variety of risky behavior indicators. Potential mechanisms for these effects include alcohol consumption, parental employment, household income, family stability, and time use. This work demonstrates that policies controlling parental substance access can have important effects on child health.

Adverse childhood experiences and risky behaviors in Oman: A cross-sectional study.

Objective: Adverse childhood experiences (ACEs), which refer to potentially traumatic events occurring during childhood, have been consistently linked to detrimental effects on high-risk behaviors through various studies. Nonetheless, such an association has rarely been examined in the context of Arab culture. This study aimed to investigate the association between ACE levels and high-risk behaviors (e.g., smoking, alcohol consumption, drug use, high-risk sexual behavior, and physical inactivity) among Omani adults. Methods: This was a cross-sectional study with convenience sampling. The participants were recruited from a university-affiliated medical facility in Oman. Data were collected in 2022. They were asked to complete the Adverse Childhood Experience International Questionnaire (ACE-IQ). Results: The study included 1648 Omani adults. Analyses revealed that the adjusted odds ratios (ORs) for engaging in some of the identified high-risk behaviors increased as the level of ACEs increased. Specifically, individuals with an ACE level of 4 exhibited higher odds of smoking (OR: 2.6), alcohol consumption (OR: 2.9), and risky sexual behavior (OR: 32) than those without ACEs. Conclusion: The findings of this study underscore a notable association between ACEs and high-risk behaviors among Omani adults. Consequently, there is a pressing need for intensified efforts to prevent ACEs when possible and to alleviate their adverse effects, emphasizing the importance of public health initiatives and interventions in Oman.

Sociodemographic Factors, Health-Risk Behaviors, and Chronic Conditions Are Associated with a High Prevalence of Depressive Symptoms: Findings from the Indonesian Family Life Survey-5.

Depression is a significant public health challenge. However, limited research exists regarding the risk of sociodemographic factors, health-risk behavior, and chronic conditions in relation to the development of depression in Indonesia. This study assesses the prevalence of depressive symptoms in adolescents and adults, and identifies its potential associations with sociodemographic factors, health-risk behaviors, and chronic conditions. A national cross-sectional population-based survey was performed, using the Indonesian Family Life Survey (IFLS-5), to assess depressive symptoms in respondents aged 15 years and older. Depression was evaluated using the Center for Epidemiologic Studies-Depression (CES-D) scale, and potential associations with sociodemographic factors, health-risk behaviors, and chronic conditions were examined using logistic regression analysis. The study revealed a high prevalence of depressive symptoms, with the highest incidence observed in the age group of 25-34 years. Factors such as unmarried status, younger age, good physical activity, and having chronic conditions showed associations with depression. These findings have implications for developing public mental health strategies to reduce the prevalence of depression in Indonesia.

Multiple risk-taking behaviors in Korean adolescents and associated factors: 2020 and 2021 Korea youth risk behavior web-based survey.

OBJECTIVE: Despite the negative health impact of multiple risk-taking behaviors (RTBs), there is a lack of understanding of adolescents who are more prone to multiple RTBs. This study aimed to identify sociodemographic, mental, and physical health variables associated with increased susceptibility to multiple RTBs in each sex. METHODS: Cross-sectional data from the 2020 and 2021 Korea Youth Risk Behavior Web-based Survey was used. A total of 106,979 Korean adolescents (55,460 men and 51,519 women) were assessed on five RTBs (alcohol use, smoking, sexual intercourse, illicit substance use, no seat belt wearing). In comparison to no RTB group, odds ratios of the relevant covariate factors were calculated in one RTB or multiple RTBs groups. RESULTS: Male and female adolescents engaging in multiple RTBs were 6.4% and 3.8%, respectively. Increasing age, low subjective socioeconomic status, and living in rural areas were associated with multiple RTBs regardless of sex. All mental health variables except anxiety were associated with multiple RTBs in both sexes. Physical inactivity and obesity were associated with decreased odds of multiple RTBs in both sexes. CONCLUSION: This study identifies diverse factors associated with multiple RTBs of Korean adolescents and demonstrates existing sex differences. Age and mental health status are the most critical factors that distinguish multiple risk-taking groups from those involved in one or no RTB.

Effectiveness of Harm Reduction Interventions in Chemsex: A Systematic Review.

The phenomenon of chemsex has emerged as an essential public health issue in recent years. This systematic review aimed to investigate currently available harm reduction strategies and to evaluate the efficacy of the corresponding interventions. METHODS: A systematic review of the scientific literature related to harm and risk reduction strategies and the effectiveness of chemsex interventions. Between January 2024 and May 2024, the articles were retrieved from the electronic databases Pubmed, Web of Science, Scopus, PsycInfo, Cochrane, Dialnet, CUIDEN, and SciELO. The review protocol was registered in the PROSPERO database (registration number CRD42024508953). The inclusion criteria were as follows: (I) original studies published in peer-reviewed journals, (II) studies exploring harm reduction interventions for chemsex, and (III) studies reflecting the efficacy of harm reduction interventions for chemsex. Two reviewers independently selected articles by title, abstract, and full paper review and extracted data. Two authors described the selected studies and assessed their methodological quality. RESULTS: The systematic review comprised six scientific papers that met the selection criteria and were obtained from five countries. Although a limited number of studies were included, it was observed that they presented a medium-high methodological quality. Programs evaluated interventions to reduce harm from chemsex, such as a web-based intervention that improved self-efficacy to refuse risky behaviors and accept HIV testing. The studies suggested that peer-led programs can be effective, especially with facilitators who have experienced chemsex dependence. CONCLUSION: Harm reduction strategies in chemsex are effective and should be promoted by health professionals. Interventions should be accessible, personalized, and non-judgmental to provide appropriate care and support, ensuring a comprehensive and effective public health response.

Sociodemographic, Clinical, and Behavioral Factors Associated with Sexual Transmitted Infection among HIV-1 Positive Migrants in Portugal: Are There Differences between Sexes?

INTRODUCTION: Sexually transmitted infections (STIs) continue to occur at high levels. According to the WHO, each year there are an estimated 374 million new infections with syphilis, gonorrhea, chlamydia, and trichomoniasis. STIs are associated with an increased risk of acquiring HIV infection. Migrants are reportedly highly affected by STIs. OBJECTIVES: This study aims to characterize factors associated with STIs in a population of HIV-positive migrants living in Portugal. METHODOLOGY: This is a cross-sectional observational study of 265 newly diagnosed HIV-1 positive migrants, who were defined as individuals born outside Portugal. This group of people were part of the BESTHOPE study that was developed in 17 Portuguese hospitals between September 2014 and December 2019, and included information collected through sociodemographic and behavioral questionnaires filled in by the migrant patients, clinical questionnaires filled in by the clinicians and HIV-1 genomic sequences generated through resistance testing (Sanger sequencing). A multivariable statistical analysis was used to analyze the association between sociodemographic characteristics, sexual behaviors, HIV testing and sexual infections. RESULTS: Most HIV-1 positive individuals included in the study were men (66.8%) and aged between 25 and 44 years old (59.9%). Men had a higher proportion of STIs when compared to women (40.4% vs. 14.0%) and the majority of men reported homosexual contacts (52.0%). Most men reported having had two or more occasional sexual partners in the previous year (88.8%) and 50.9% reported always using condoms with occasional partners, while 13.2% never used it. For regular partners, only 29.5% of the women reported using condoms, compared to 47.3% of men. Other risk behaviors for acquiring HIV, such as tattooing and performing invasive medical procedures, were more prevalent in men (38.0% and 46.2%, respectively), when compared to women (30.4% and 45.1% respectively) and 4.7% of men reported having already shared injectable materials, with no data for comparison in the case for women. Additionally, 23.9% of women reported having had a blood transfusion while only 10.3% of men reported having had this medical procedure. Meanwhile, 30.9% of the individuals reported having been diagnosed with some type of STI in the last 12 months. In addition, 43.3% of individuals that answered a question about hepatitis reported to be infected with hepatitis B, while 13.0% reported having hepatitis C infection. According to the multivariable analysis, the only transmission route was significantly associated with reports of previous STI infection: men who have sex with men (MSM) were 70% more likely to have been diagnosed with an STI in the past 12 months compared to the heterosexual route. CONCLUSION: HIV-1 infected men were more likely to report previous STIs than women. On the other hand, most migrant women had a regular sexual partner and never or only sometimes used condoms. This somewhat discrepant findings suggest that gender inequalities may make women unable to negotiate safe sexual practices, resulting in increased susceptibility to infection. However, since migrant women report less STIs, we cannot exclude that these STIs may remain undiagnosed. The implementation of safer sex awareness campaigns for condom use and screening for STIs in women is crucial. On the other hand, health education campaigns for STI knowledge need to be implemented for both MSM and women and their partners.

Can Support Groups Improve Treatment Adherence and Reduce Sexual Risk Behavior among Young People Living with HIV? Results from a Cohort Study in South Africa.

Adolescents and young adults living with HIV (AYLHIV) in sub-Saharan Africa experience poorer HIV outcomes than adults, including lower ART adherence and virologic suppression. They also have high rates of unprotected sex, increasing the risk of adverse sexual health outcomes and onward transmission. This one-arm, pre-post study investigates a structured 14-session support group aiming to boost treatment adherence and sexual protective behavior for AYLHIV in South Africa. Logistic and Poisson regression analyses were performed on self-reported pre- and post-intervention survey data collected approximately 7.5 months apart from a cohort of 548 AYLHIV. Participants were significantly more likely to report at least 95% adherence at follow-up and rate their health as "good;" they also demonstrated greater treatment knowledge and had fewer absences from school overall and due to illness. Among sexually active AYLHIV, contraception use at last sex increased significantly, while condom use did not. Effects were small, and greater programmatic emphasis on adherence and multifaceted service packages is likely necessary to promote viral suppression. Nonetheless, the intervention addresses an important gap in service provision for AYLHIV in South Africa. Findings denote the potential for incorporating care and treatment components into sexual and reproductive health interventions tailored for AYLHIV.

Nonconforming gender expression and adolescent anabolic-androgenic steroids misuse.

BACKGROUND: Gender nonconformity (GNC) is an under-researched area of adolescent health that is of increasing interest to researchers and general public. However, little is known about whether it is associated with anabolic-androgenic steroids (AAS) misuse. We aimed to investigate the association among high school students using a cross-sectional design. METHODS: We pooled the 6 school districts data from the Youth Risk Behavior Survey in 2017 and 2019. We compared the prevalence of AAS misuse among gender nonconforming and conforming students. AAS misuse was determined on the reported experience of lifetime non-prescription steroid use. GNC was derived from perceived gender expression and sex. We estimated the sex-stratified adjusted odds ratios (AORs) for the association of GNC with AAS misuse after adjusting for race/ethnicity, grade, and sexual orientation. RESULTS: The study population consisted of 17,754 US high school students including 9143 (49.67%) female students. Among female students, GNC was significantly associated with moderate (AOR, 3.69; 95% CI 1.28-10.62; P = 0.016) and severe (AOR, 5.00; 95% CI 1.05-23.76; P = 0.043) AAS misuse, but not with any AAS misuse (AOR, 0.85; 95% CI 0.34-2.14; P = 0.734). Among male students, GNC was significantly associated with any (AOR, 4.75; 95% CI 2.93-7.69; P < 0.001), moderate (AOR, 4.86; 95% CI 2.66-8.89; P < 0.001) and severe (AOR, 4.13; 95% CI 1.43-11.95; P = 0.009) AAS misuse. We did not observe a dose-response relationship between GNC and any AAS misuse in female and male students. CONCLUSIONS: This study suggests that AAS misuse is associated with GNC among female and male adolescents.

The Role of Parenting Behaviors and Their Influence on Adolescent Drunk and Drugged Driving: 2016-2019, USA.

Drugged driving, the act of driving a vehicle under the influence of illicit drugs, by adolescents is a serious public health concern. Many factors contribute to this risk behavior, but much less is known regarding the role of parenting behaviors in this phenomenon. The purpose of this study was to examine specific parenting behaviors and their influence among a nationally representative sample of adolescents. Pooled data from the 2016-2019 National Survey on Drug Use and Health (NSDUH) among 17,520 adolescents ages 16-17 years old were analyzed. Differences were found in specific parenting behaviors and adolescent drugged/drunk driving, with parents not checking homework and not telling their children they are proud of them being the most influential. Findings from the present study may inform drugged driving prevention programs for parents and adolescents and enhance road safety interventions.

The Impact of Poverty on Children's Well-Being and Health Behavior Based on the Results of Research Conducted in One of Hungary's Most Disadvantaged Micro-Regions.

This empirical research on children's poverty and the accompanying risk behavior was conducted in the Baktalórántháza micro-region, in one of the most disadvantaged micro-regions of Hungary. The study, completed in 2023, was conducted utilizing three methods, a questionnaire for families, interviews, and focus group interviews with social professionals working in the settlements. The region is one of the ten micro-regions with the highest poverty rate in the country. The majority of the population only has an elementary education, and the proportion of graduates is much lower than the national average. The proportion of households with three or more children is higher than the national average and the proportion of unemployed people in households with children is twice as high as the national average. Based on the experience of social workers working in the area, in addition to smoking and drinking alcohol, the consumption of psychoactive and psychotropic substances has increased among adolescents and young adults. Based on various indicators, children regularly consume illegal drugs. The origin and composition of these drugs are typically unknown. According to the reports by drug users, everyday life is easier, and they can escape from problems when under the influence of drugs. Based on the observations of experts, the consumption of various psychoactive substances has harmful effects on behavior, health, learning, and family life. School performance and the ability to think and learn decrease. Drug users are dissatisfied with their lives, have problems with social relationships, engage in partner violence, and may develop antisocial behavior in their lives.

Factors Associated With Gun Possession Among High-School Students in the U.S. Before and During the Pandemic.

Background: Adolescents' possession of guns was a matter of concern even before the pandemic. It is pertinent to examine whether students continued possessing guns after schools reopened, and if so, identify factors that might have been associated with such behaviors. Towards this end, the present study examined the relationship between highschool students' experiences and their propensity to possess guns. Methods: This used responses from multiple nationally representative cross-sectional surveys of high school students from the 2019 and 2021 Youth Risk Behavior Survey (YRBS) and the 2021 Adolescent Behaviors and Experiences Survey (ABES). Gun possession within the past year was the main outcome of interest. Experiences of violence, assault, injury, and other adverse experiences were the independent variables. Bivariate and multivariate logistic regressions, adjusting for sample weights, were performed using SAS. Results: Out of a total of more than 25,000 and 38,000 valid responses, respectively in 2019 and 2021 to the question on gun possession, 4.7% and 4.2% reported carrying a gun at least once within the past year. Experiences of sexual violence, involvement in physical fight, perceived lack of safety, and being threatened/injured by weapons, were associated with higher adjusted odds of guns possession among males and females. Among ABES 2021 respondents (more than 7500), those who witnessed violence in the neighborhood were more likely to possess guns. This association was significant among males, whereas parents being informed about whereabouts was significant for females. Conclusion: This study shows that adverse experiences were associated with a higher odds of guns possession among female and male highschool students. Witnessing violent attack on someone in the neighborhood emerged as a risk factor for males. This suggests that social determinants of health as well as adverse experiences are associated with gun possession among high-school students.

Sexual risk behavior and knowledge about sexually transmitted infections in a university population in Sorocaba, Brazil

Introduction: Sexually transmitted infections (STIs) are a major public health problem to which young people are highly exposed and knowledge about vulnerabilities that affect them is needed. Objective: To evaluate the knowledge about STIs and sexual behavior of a university population in the city of Sorocaba/SP. Methods: A descriptive, cross-sectional study was conducted with data collection realized by an online application with qualitative and quantitative characteristics. Results: Four hundred and seventy-seven (477) university students from different areas of knowledge were analyzed. The majority pointed to the beginning of sexual life between 15 and 18 years old. Information about sex education was obtained mainly through parents and/ or guardians, while little additional knowledge was obtained after entering higher education. Biological and Health Sciences students achieved a higher score on the knowledge questionnaire and were less likely (0.391) to contract STIs when compared to Applied Social Sciences or Engineering students (2.8 and 2.9 more likely, respectively). Conclusion: Students who demonstrated greater knowledge about STIs and acquired more information on the subject during graduation were less likely to become infected, suggesting that campaigns aimed at the university public are essential for the prevention and control of these pathogens.

The Interplay Between Household Risk Perception of Parasitic Infections and Water, Sanitation, and Hygiene (WASH) Practices: Evidence From an Urban Poor Community in the Philippines.

BACKGROUND: Parasitic diseases pose challenges in impoverished urban settlements with limited access to clean water, proper hygiene, and sanitation (WASH). This study assesses WASH practices and risk perceptions of parasitic infections among households in the Bataan Shipyard and Engineering Corporation (BASECO) Compound in Manila, an urban poor community in the Philippines. METHODS: A cross-sectional study design was employed to collect data through a self-administered questionnaire. Descriptive statistical analysis was performed to assess the sociodemographic profile, household WASH practices, and respondents' risk perception of parasitic infections. Linear regression analysis was utilized to examine the relationship between these variables. RESULTS: A survey was conducted with 363 households, of which 237 (65.3%) used distilled and purified water from the water refilling stations in the community for drinking. Meanwhile, 120 households (33.10%) consumed tap water. Boiling water was a commonly used method (n=146; 56.60%) for treating drinking water. Most households had flush toilets with septic tanks (n=244; 67.20%), water sources for handwashing (n=307; 84.57%) and soap for handwashing (n=356; 98.10%). On average, they washed their hands 6-10 times daily (n=159; 43.80%). Most households were aware that drinking untreated water (n=318; 87.6%), improper food washing (n=309; 85.1%), using contaminated water sources (n=301; 82.9%), and consuming raw or undercooked meat (n=298; 82.1%) could lead to parasitic infections. 316 respondents (87.1%) identified diarrhea as the most common symptom of parasitic infection. Relationships were found between access to drinking water and the number of household members (B=0.191; p-value=0.001), personal hygiene and the respondents' knowledge of parasitic infections (B=0.112; p-value=0.047), and the overall WASH score with household income (B=0.105; p-value=0.045). CONCLUSIONS: The WASH conditions in BASECO, Manila need improvement. Factors associated with their WASH practices include risk perception of parasitic diseases, socioeconomic disparity, and household overcrowding. These factors play a crucial role in identifying areas for improvement and promoting health policies for urban poor communities in the Philippines.

Prescription drug monitoring programs and prescription pain medication misuse among U.S. high school students-2019.

BACKGROUND: Prescription drug monitoring programs (PDMPs) are state-level databases that track and inform prescribing practices to reduce prescription drug diversion and misuse. To our knowledge, only three studies have examined the impact of PDMPs on opioid-related outcomes among adolescents, and none have focused on prescription pain medication misuse among adolescents. METHODS: This study leveraged data from the 2019 National Youth Risk Behavior Survey (YRBS) to explore the associations between five categories of PDMP dimensions and the prevalence of self-reported prescription pain medication misuse. Demographic factors' associations with self-reported prescription pain medication misuse were also examined. RESULTS: In 2019, none of the PDMP dimensions were associated with self-reported prescription pain medication misuse among U.S. high school students, adjusting for gender, grade, race/ethnicity, and sexual orientation. CONCLUSIONS: None of the five PDMP dimensions were associated with lower prescription pain medication misuse, however further research is needed, especially as new YRBS data become available.

Machine Learning-Based Prediction of Suicidal Thinking in Adolescents by Derivation and Validation in 3 Independent Worldwide Cohorts: Algorithm Development and Validation Study.

BACKGROUND: Suicide is the second-leading cause of death among adolescents and is associated with clusters of suicides. Despite numerous studies on this preventable cause of death, the focus has primarily been on single nations and traditional statistical methods. OBJECTIVE: This study aims to develop a predictive model for adolescent suicidal thinking using multinational data sets and machine learning (ML). METHODS: We used data from the Korea Youth Risk Behavior Web-based Survey with 566,875 adolescents aged between 13 and 18 years and conducted external validation using the Youth Risk Behavior Survey with 103,874 adolescents and Norway's University National General Survey with 19,574 adolescents. Several tree-based ML models were developed, and feature importance and Shapley additive explanations values were analyzed to identify risk factors for adolescent suicidal thinking. RESULTS: When trained on the Korea Youth Risk Behavior Web-based Survey data from South Korea with a 95% CI, the XGBoost model reported an area under the receiver operating characteristic (AUROC) curve of 90.06% (95% CI 89.97-90.16), displaying superior performance compared to other models. For external validation using the Youth Risk Behavior Survey data from the United States and the University National General Survey from Norway, the XGBoost model achieved AUROCs of 83.09% and 81.27%, respectively. Across all data sets, XGBoost consistently outperformed the other models with the highest AUROC score, and was selected as the optimal model. In terms of predictors of suicidal thinking, feelings of sadness and despair were the most influential, accounting for 57.4% of the impact, followed by stress status at 19.8%. This was followed by age (5.7%), household income (4%), academic achievement (3.4%), sex (2.1%), and others, which contributed less than 2% each. CONCLUSIONS: This study used ML by integrating diverse data sets from 3 countries to address adolescent suicide. The findings highlight the important role of emotional health indicators in predicting suicidal thinking among adolescents. Specifically, sadness and despair were identified as the most significant predictors, followed by stressful conditions and age. These findings emphasize the critical need for early diagnosis and prevention of mental health issues during adolescence.

Food insecurity and use of electronic vapor products among high school students.

Background: Studies have shown that food insecurity is associated with electronic vapor products (EVP) use in adults; however, an understanding of this relationship in adolescents is needed to inform prevention efforts in this age group. Aim: Examine the relationship of food insecurity with EVP use patterns, frequency and source of acquisition in high school students. Methods: This cross-sectional study used Youth Risk Behavior Survey (YRBS) 2019 data from states that incorporated the YRBS' optional food insecurity question. The data included 42,154 high school students with complete information on food insecurity and two EVP-related questions. Responses to EVP-related questions identified "ever users," "current users," "former users," "current dual EVP-cigarette users," and assessed "frequency of EVP use among current users" and "source of EVP acquisition." Logistic regression examined associations of food insecurity with EVP-related outcomes. Results: The proportion of high school students who ever used EVP was 48.3% and the proportion of food-insecure students was about 12%. Food security status significantly differed by race/ethnicity of students, such that the proportion of food insecure students classified as "non-Hispanic White" was lower than the proportion of food secure students classified as "non-Hispanic White." Food insecurity was significantly associated with greater odds of ever EVP use (odds ratio (OR) = 1.75; 95% confidence interval (CI) = (1.55, 1.96)), current EVP use (OR = 2.07; 95% CI = (1.80, 2.37); using never users as reference category) and current dual use of EVP and cigarettes (OR = 2.91; 95% CI = (2.38, 3.55)). Food insecurity also was associated with greater odds of current EVP use (OR = 1.54; 95% CI = (1.28, 1.84)) when former users were used as reference category. In current users, food insecurity was related to greater odds of daily EVP use (OR = 1.40; 95% CI = (1.14, 1.70)) compared to occasional use. Conclusions: Study findings imply that efforts targeting prevention/cessation of EVP use should consider reducing food insecurity in high school students.

Unifying Public Health Surveillance: A Scoping Review of Global Use of the Youth Risk Behavior Survey.

PURPOSE: The Youth Risk Behavior Survey (YRBS) is a well-established surveillance tool designed to document the health risk behaviors of youth. However, there is limited insight into the use of the survey outside of the United States. The aim of this scoping review was to assess the global presence and utilization of the YRBS. METHODS: A structured electronic search of all publication years (through February 2020) was conducted to identify articles in PubMed and EBSCOhost. The search identified 128 articles that used the YRBS beyond the United States. RESULTS: More than one-third of all countries, territories, and dependencies were represented in the articles, with the greatest use among upper-middle and high-income economies and those in the East Asia and Pacific geographic region. Priority health-risk behaviors identified were alcohol and other drug use (51%), tobacco use (48%), and unintentional and intentional injuries (44%). The articles predominantly suggested that the survey data be used to influence programs, policies, and practices (57%). DISCUSSION: The development and proliferation of surveillance systems has allowed for important contributions to public health. Extensive use of the YRBS is notable; however, greater efforts are needed to support more systematic and collaborative approaches for evaluating youth behaviors around the world.
