The role of monitoring skills in mediating the association between parent's hazardous alcohol consumption and adolescents' drinking.

BACKGROUND: This study aimed to investigate whether parental monitoring skills mediate the effect of hazardous parental alcohol consumption on adolescents' lifetime alcohol use. METHODS: This three wave longitudinal study was conducted with 884 families (n = 1,768 participants) to evaluate the effectiveness of a family-based drug prevention program for adolescents and parents across 12 Brazilian cities. We used structural equation mediation modeling to analyze the effect of hazardous parental alcohol consumption at baseline on adolescents' lifetime alcohol use at 12-month follow-up, mediated by parental monitoring skills latent dimension at 6-month follow-up. RESULTS: We found a significant indirect effect of parents' hazardous alcohol use on adolescents' alcohol use through parental monitoring (OR:1.18, 95%CI:1.02;1.36). CONCLUSION: Our finding underscores the importance of comprehensive preventive family alcohol approaches targeting adolescent alcohol use, which should consider both parental drinking behavior and monitoring practices.

Consumo e exposição a bebidas alcoólicas entre adolescentes brasileiros: evidências das pesquisas nacionais de saúde do escolar de 2015 e 2019 / Consumo y exposición a bebidas alcohólicas entre los adolescentes brasileños: evidencia de las encuestas nacionales de salud escolar de 2015 y 2019 / Consumption of and exposure to alcoholic beverages among brazilian adolescents: diverse evidence from the 2015 and 2019 national school health surveys

RESUMO Objetivo: analisar os indicadores de consumo e exposição a bebidas alcoólicas entre escolares brasileiros em 2019 e compará-los aos de 2015. Método: estudo transversal com dados da Pesquisa Nacional de Saúde do Escolar (PeNSE), realizadas em 2015 e 2019. Em 2019, analisaram-se os indicadores referentes ao consumo e à exposição a bebidas alcoólicas, estratificadas por sexo, faixa etária, dependência administrativa, unidades da federação e região geográfica. Estimou-se as prevalências e os respectivos intervalos de 95% de confiança (IC 95%). Resultados: houve aumento na experimentação de bebidas alcoólicas antes de 13 anos (30,6% em 2015 para 34,6% em 2019); sofrer embriaguez na vida (27,2% em 2015 para 47,0% em 2019) e ter problemas com amigos devido ao consumo de bebidas alcóolicas (9,3% em 2015 para 15,7% em 2019). Todos os indicadores foram mais prevalentes entre meninas, exceto beber em binge e episódios de embriagues, que não tiveram diferenças entre os sexos, bem como foram mais elevadas entre estudantes mais velhos. Os episódios de embriaguez e ter amigos que ingerem bebida alcoólica foram mais prevalentes entre escolares de escolas públicas, enquanto o consumo de bebidas alcoólicas pelos pais e ter tido problemas com suas famílias ou amigos devido ao consumo de bebidas alcoólicas foram mais elevados em estudantes de escolas privadas. Conclusão: evidenciaram-se elevadas prevalências de experimentação, consumo e exposição a bebidas alcoólicas, mostrando que grande parcela dos adolescentes brasileiros se encontra exposta a uma carga evitável de morbimortalidade decorrente do consumo e exposição ao álcool.

RESUMEN Objetivo: analizar los indicadores de consumo y exposición a bebidas alcohólicas entre los estudiantes brasileños en 2019 y compararlos con los de 2015. Método: estudio transversal con datos de la Encuesta Nacional de Salud Escolar (PeNSE), realizada en 2015 y 2019. En 2019 se analizaron los indicadores referidos al consumo y exposición a bebidas alcohólicas estratificados por sexo, grupo de edad, dependencia administrativa, unidades federativas y región geográfica. Se estimó la prevalencia y los respectivos intervalos de confianza del 95% (IC 95%). Resultados: aumenta la experimentación con bebidas alcohólicas antes de los 13 años (30,6% en 2015 a 34,6% en 2019); sufrir borracheras en la vida (27,2% en 2015 a 47,0% en 2019) y tener problemas con los amigos por el consumo de alcohol (9,3% en 2015 a 15,7% en 2019). Todos los indicadores eran más frecuentes entre las chicas, excepto el consumo compulsivo de alcohol y los episodios de embriaguez, que no presentaban diferencias de género, además de ser más elevados entre los estudiantes de mayor edad. Los episodios de consumo de alcohol y el hecho de tener amigos que beben bebidas alcohólicas fueron más frecuentes entre los estudiantes de la escuela pública, mientras que el consumo de alcohol por parte de los padres y el hecho de haber tenido problemas con sus familias o amigos debido al consumo de alcohol fueron mayores en los estudiantes de las escuelas privadas. Conclusión: se evidenció una alta prevalencia de experimentación, consumo y exposición a bebidas alcohólicas, mostrando que una gran parte de los adolescentes brasileños está expuesta a una carga evitable de morbilidad y mortalidad resultante del consumo y exposición al alcohol.

ABSTRACT Objective: to analyze the indicators regarding consumption of and exposure to alcoholic beverages among Brazilian schoolchildren in 2018 and compare them to those from 2015. Method: a cross-sectional study conducted with data from the 2015 and 2019 National School Health Survey (Pesquisa Nacional de Saúde do Escolar, PeNSE). In 2019, the indicators referring to consumption of and exposure to alcoholic beverages were analyzed, stratified by gender, age group, administrative system, Federation Unit, and geographical region. The prevalence values and their respective 95 confidence intervals (95% CIs) were estimated. Results: there was an increase in trying alcoholic beverages before the age of 13 (from 30.6% in 2015 to 34.6% in 2019); being drunk in their lifetime (from 27.2% in 2015 to 47.0% in 2019) and having problems with friends due to alcohol consumption (from 9.3% in 2015 to 15.7% in 2019). All the indicators were more prevalent among the girls, except for binge drinking and drunkenness episodes, which presented no differences between the genders and were also higher among older students Episodes of drunkenness and having friends who drink alcohol were more prevalent among students from public schools, while consumption of alcoholic beverages by parents and having had problems with their families or friends due to alcohol consumption were higher in students from private schools. Conclusion: high prevalence of experimentation, consumption and exposure to alcoholic beverages was evidenced, showing that a large number of Brazilian adolescents are exposed to an avoidable burden of morbidity and mortality resulting from consumption of and exposure to alcohol.

Impacto da exposição domiciliar ao tabaco e da composição familiar sobre a precocidade de uso de tabaco e álcool em adolescentes brasileiros / Impact of household exposure to tobacco and family composition on the early onset of alcohol use in Brazilian adolescents

O uso precoce de tabaco e álcool associa-se à maior morbimortalidade e manutenção desse consumo na vida adulta. Esta tese investiga o papel de fatores domiciliares e familiares sobre o início precoce do uso dessas substâncias entre adolescentes. Os dados analisados são do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA), que investigou 74.589 adolescentes de escolas públicas e privadas, com idades entre 12 e 17 anos, residentes de 124 municípios com mais de 100 mil habitantes no país. O primeiro manuscrito teve como objetivo estimar o efeito da presença de fumantes no domicílio sobre o início mais precoce de tabagismo entre adolescentes. O segundo manuscrito teve como objetivo estimar o efeito da composição familiar sobre o início mais precoce de tabagismo e do uso de álcool entre adolescentes. Em ambas as análises foram usados Modelos de Regressão de Cox não ajustados e ajustados por um conjunto de variáveis com intuito de controlar vieses de confundimento. Os Hazard Ratios estimados no manuscrito 1 mostraram um aumento de 51% (IC95%: 31%-65%) na chance de um adolescente não fumante e exposto ao tabaco em casa começar a fumar mais precocemente do que aquele que não convivia com tabagistas no domicílio. Nos resultados do segundo manuscrito observou-se uma influência importante da composição familiar sobre a precocidade de início do uso de tabaco e álcool entre adolescentes. Segundo os Hazard Ratios estimados, houve um aumento de 68% (IC95%: 50%-89%) na chance de um adolescente não fumante que não residia com ambos os pais iniciar o uso de tabaco antes de um adolescente que residia com pai e mãe. Quanto àqueles que residiam apenas com a mãe ou apenas com o pai, esse aumento foi de 46% (IC95%: 32%-60%) e 54% (IC95%: 28%-84%), respectivamente. Em relação ao início do consumo de bebidas alcoólicas, observou-se um aumento de 35% (IC95%: 21%-52%) na chance de um adolescente que não bebe e não reside com pai e mãe de iniciar o uso de álcool mais precocemente do que aqueles que residiam com ambos os pais. Quanto aos adolescentes que residiam apenas com a mãe ou apenas com o pai, esse aumento foi de 22% (IC95%: 17%-28%) e 36% (IC95%: 24%-50%), respectivamente. O terceiro manuscrito teve como objetivo investigar o uso conjunto de tabaco e álcool através de análises de coocorrência e de agrupamento, assim como descrever a relação temporal do início do uso das duas substâncias entre adolescentes tabagistas e usuários de álcool. Para a análise de agrupamento foram obtidas razões entre os valores observados (O) e esperados (E) de uso de tabaco e álcool. Na amostra total a razão O/E foi 3,51 (IC95%: 3,39-3,65) indicando o agrupamento do uso dessas substâncias. Já a Razão de Chances de Prevalência foi de 14,7 (IC95%: 12,4-17,4). A maior parte dos usuários (45,2%) de ambas as substâncias iniciou pelo uso de álcool. Nossos resultados reforçam as propostas de que ações preventivas não devem estar focadas em cada droga isoladamente, e devem incluir não só o adolescente, mas também seu universo familiar.

Early use of tobacco and alcohol is associated with increased morbimortality and maintenance of their use during adulthood. This thesis investigates the role of household and family factors on adolescents' early onset of these substances. The data analyzed are from the Cardiovascular Risk Factors Study (ERICA), which investigated 74,589 adolescents from public and private schools, aged between 12 and 17 years old, living in 124 municipalities with more than 100 thousand inhabitants in the country. The first manuscript aimed to estimate the effect of the presence of smokers in the household on the earlier onset of smoking habit among adolescents. The objective of the second manuscript was to estimate the effect of family composition on the earlier onset of smoking and alcohol use among adolescents. In both analyses, unadjusted and adjusted Cox Regression Models were used to control for confounding variables. The Hazard Ratio estimated in manuscript 1 showed a 51% increase (95% CI: 31%-65%) in the chance that a nonsmoking adolescent exposed to tobacco at home would start smoking earlier than one who did not live with smokers. The results of the second manuscript depicted an important impact of family composition on the early onset of tobacco and alcohol use among adolescents. According to the estimated Hazard Ratios, there was a 68% increased chance (95% CI: 32%-60%) that a nonsmoking adolescent who did not live with both parents would initiate tobacco use earlier than an adolescent living with both parents. As for those who resided with only the mother or only the father, the increase was 46% (95% CI:32%-60%) and 54% (95%CI: 28%-84%), respectively. Regarding the onset of consumption of alcoholic beverages, there was a 35% increase (95% CI:21%-52%) in the chance of an adolescent who does not drink and does not reside with both parents to initiate alcohol use earlier than those living with the mother and the father. As for adolescents living only with the mother or only the father, this increase was 22% (95%CI: 17%-28%) and 36% (95%CI: 24%-50%), respectively. The third manuscript investigated the concurrent use of tobacco and alcohol through co-occurrence and clustering analyses. It also described the temporal relationship between the onset of tobacco and alcohol use among adolescents consuming both substances. For the clustering analysis, we calculated ratios between observed (O) and expected (E) values of tobacco and alcohol use. In the total sample, the O/E ratio was 3.51 (95% CI: 3.39-3.65), indicating the clustering of the use of these substances. The prevalence odds ratio was 14.7 (95% CI: 12.4- 17.4). Most of the users (45.2%) of both substances started with the use of alcohol. Our results reinforce the proposal that preventive actions should not be focused on each drug separately and should include the adolescents and their families.

Alcohol Availability, Use, and Harms Among Adolescents in Three Mexican Cities.

Alcohol remains readily available to youth in most countries. We examined the associations between both the on- and off-premises commercial availability of alcohol to youth and their alcohol use, heavy episodic drinking, and alcohol-related harms. We conducted the study using data from a survey of a sample of 594 students in central Mexico between 12 and 17 years of age in 2016. Both the perceived availability of alcohol and the purchasing of alcohol at an off-premises establishment were positively related to past-30-day alcohol use and heavy episodic drinking, as well as to alcohol-related harms in the past year. Consumption at on-premises establishments was also positively associated with alcohol-related harms. Preventive efforts to reduce the availability of alcohol at off- and on-premises establishments, by such strategies as mystery shopper and responsible beverage service programs, are imperative.

How important is school environment in explaining individual variance of health behaviors?

We analyzed data from the National School-based Health Survey (PeNSE) carried out in Brazil in 2015 (n = 102,072 adolescents) to estimate how much of the individual variance in the prevalence of health behaviors is attributable to the school level. Multilevel logistic regression models were calculated to estimate the variance partitional coefficient (VPC) of the use of drugs, intake of unhealthy food, leisure physical activity and weight-related behaviors. The between-schools variance was significant in all tested models. The highest VPCs were observed when the use of drugs was analyzed (15%-20% of the total variance of smoking and use of illegal drugs). Lower, but still significant, values were observed in the other outcomes. The school context plays an important role in the adolescents' health and should be considered in the design of public policies and actions in public health.

Determinantes sociales del consumo de alcohol en adolescentes del Colegio Daniel Córdova de Cuenca: estudio transversal, 2016 / Social determinants of alcohol consumption in adolescents from Daniel Cordova High School in Cuenca: cross sectional study, 2016

Introduction: the alcohol consumption in adolescence is frequent and it is associated with social determinants. The objective of the study was to determine the prevalence of alcohol consumption in adolescents of the Daniel Córdova High School in Cuenca - Ecuador and its association with some social determinants.Methods: it is a cross-sectional study, with a sample of 218 adolescents. A questionnaire for demo-graphic variables, family structure and migration was used to determine the prevalence of alcohol consumption, the diagnostic criteria of the DSM5 was used to identify the family functioning of the FF-SIL Test and for the lifestyle the FANTASTIC test was applied. The PR was obtained with its confidence intervals to control if the social determinants were a risk or protection factor for the alcohol consumption, and the statistical significance was determined with values of p <0.05.Results: the prevalence of alcohol consumption was 42.2%; a total of 56% of the students come from a "nuclear home", the 55% have a migrant relative, 39% have a good lifestyle and 50% be-long to families qualified as moderately functional. There is a statistically significant association with the fact of having a migrant family member, having a bad lifestyle and belonging to a reconstituted and dysfunctional family.Conclusion: the prevalence of alcohol consumption is higher than those reported in other studies carried out in Cuenca city high schools; It is associated with similar social determinants globally.(AU).

Introducción: el consumo de alcohol en la adolescencia es frecuente y se encuentra asociado a determinantes sociales. El objetivo de nuestro estudio fue determinar la prevalencia de consumo de alcohol en los adoles-centes del colegio "Daniel Córdova" de Cuenca ­ Ecuador y su asociación con algunos determinantes sociales.Métodos: estudio transversal, en una muestra de 218 adolescentes. Se usó un cuestionario para las variables demográficas, estructura familiar y migración; para determinar la prevalencia de consumo de alcohol se usó los criterios diagnósticos del DSM5, para identificar el funcionamiento fa-miliar el Test FF-SIL y para el estilo de vida el test FANTASTIC. Se obtuvo la RP con sus intervalos de confianza para determinar si los determinantes sociales fueron factor de riesgo o de protección para el consumo de alcohol y la significancia estadística se determinó con valores de p<0.05. Resultados: la prevalencia del consumo de alcohol fue del 42.2 %; el 56% de los estudiantes provienen de un "hogar nuclear", el 55% tienen algún fa-miliar migrante, el 39% tienen un buen estilo de vida y el 50% pertenecen a familias calificadas como moderadamente funcionales y existe asociación estadísticamente significativa con el hecho de tener un familiar migrante, poseer un mal estilo de vida y pertenecer a una familia reconstituida y disfuncional. Conclusión: la prevalencia del consumo de alcohol es mayor que los re-portados en otros estudios realizados en colegios de la ciudad de Cuenca y se asocia con determinantes sociales similares a nivel global.(AU).

Contributions of parenting styles and parental drunkenness to adolescent drinking

Objective: To estimate the association of parental drunkenness and parenting style with alcohol consumption among adolescents and the contributions of parental drunkenness and parenting style to the prevalence of binge drinking among adolescents. Method: Cross-sectional survey of a representative sample of secondary students aged 13 to 18 from 27 Brazilian state capitals (n=17,028). Private and public schools were included. A self-report questionnaire collected data on adolescents' alcohol drinking behavior, parenting styles, and parenting and peer models of drunkenness. Results: Non-authoritative parenting style and parental drunkenness are associated with binge drinking among adolescents. Authoritarian, indulgent, and negligent parenting styles were associated with 1.50-, 2.51-, and 2.82-fold increases in prevalence of adolescent binge drinking, and parental drunkenness, with a 1.99-fold increase. The non-authoritative parenting style made a larger contribution than parental drunkenness to adolescent binge drinking. Conclusions: Non-authoritative parenting style and parental drunkenness seem to play an important role in adolescents' binge drinking behavior. At the population level, parenting style appears associated with a greater contribution to this behavior among adolescents. Prevention strategies targeting parental drunkenness may be bolstered if a broader approach including parenting styles is in place.

Familism, sibling relationship qualities, and sibling sex constellation as predictors of alcohol use among Mexican-origin adolescents.

Sibling relationship qualities and traditional family values (i.e., familism) are contextual factors relevant for early substance use risk among Mexican-origin adolescents. Yet limited research has examined whether familism moderates the effects of sibling relationship features on alcohol use. The present study examined whether familism enhanced or reduced the effects of sibling intimacy, negativity, and sibling deviance on later alcohol use, also testing whether sibling sex constellation (sisters, brothers, mixed) modified the patterns of influence. We analyzed two waves of data (N = 404) from the California Families Project, a longitudinal study of Mexican-origin youth. Using zero-inflated Poisson models, we examined unique and intersecting prospective influences of age 14 sibling contexts and familism on the likelihood of and degree of engagement in alcohol use at age 16. Results indicated a complex interplay of sibling features, familism values, and alcohol use patterns. Familism moderated the effects of sibling intimacy on later alcohol use patterns. For those with lower familism, increasing intimacy was associated with higher probability of any use, but decreasing degree of use (especially for brother pairs and sister pairs). Among those with higher familism, increasing intimacy predicted reduced probability of any use, but increases in the degree of use (for sister and mixed pairs). More sibling negativity was related to reduced alcohol use probability for brothers, and increased alcohol use in mixed sibling pairs. Sibling deviance was associated with greater age 16 alcohol use. This study highlights cultural considerations for including siblings in substance use prevention programs for Mexican-origin youth. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Exposure to Alcohol Use in Movies and Problematic Use of Alcohol: A Longitudinal Study Among Latin American Adolescents.

OBJECTIVE: This study assesses the association between exposure to alcohol in movies and alcohol use transitions among Latin American adolescents. METHOD: A school-based longitudinal study involving 33 secondary schools in Argentina and 57 in Mexico was performed. The baseline sample included 1,504 never drinker adolescents in Argentina and 5,264 in Mexico (mean age = 12.5 years), of whom 1,055 and 3,540, respectively, completed a follow-up survey a year and a half later. Exposure to the 500 popular contemporary films was assessed by querying adolescents on 50 randomly selected titles. Films were content-coded for alcohol and exposure estimated from films seen. Logistic regression models estimated adjusted relative risk (aRR) for the following outcomes, net covariates, at follow-up: use of alcohol (having ever drank), current drinking (drinking in the past 30 days), ever binge drinking (≥ 4 drinks [females] or 5 for males). RESULTS: At follow-up, respective adolescent drinking rates for Mexico and Argentina were 31% and 36% for use of alcohol, 18% and 27% for current drinking, and 8% and 19% for ever binge drinking. Greater exposure to alcohol in movies was independently associated with trying alcohol (aRR = 1.30, 95% CI [1.17, 1.43]), current drinking (aRR = 1.22, 95% CI [1.03, 1.44]), and binge drinking (aRR = 1.71, 95% CI [1.30, 2.25]) in Mexican adolescents, whereas in Argentina, movie alcohol exposure was associated only with trying alcohol (aRR = 1.25, 95% CI [1.02, 1.53]). CONCLUSIONS: Exposure to alcohol in movies predicted underage drinking transitions in these Latin American adolescents, replicating prior results for U.S. and European cohorts.

Influence of parental smoking on the use of alcohol and illicit drugs among adolescents.

OBJECTIVE: To evaluate the association between parental smoking and the use of alcohol and illicit drugs among adolescent children. METHODS: A cross-sectional study with 6,264 adolescents (59.7% female) aged between 14 and 19 years. To establish the sample, we used two-stage cluster random sampling. The data on parental smoking and use of cigarettes, alcohol and illicit drugs among adolescents were collected using a questionnaire. RESULTS: Smoking adolescents were more prone to use alcohol (odds ratio - OR: 10.35; 95%CI: 7.85-13.65) and illicit drugs (OR: 11.75; 95%CI: 9.04-15.26) than non-smokers (p<0.001). Adolescents with at least one parent (OR: 1.4; 95%CI: 1.13-1.89) or both parents smoking (OR: 1.6; 95%CI: 1.01-2.67) were more likely to smoke when compared to those having no parents smoking. The adjusted analysis limited to non-smoking adolescents showed a positive association (p<0.05) between parental tobacco use and the use of alcohol (OR: 1.4; 95%CI: 1.23-1.62) and illicit drugs (OR: 1.6; 95%CI: 1.24-2.13), irrespective of age, sex, maternal schooling and place of residence. CONCLUSION: Parental smoking was associated with the use of alcohol and other illicit drugs by adolescents, even among nonsmokers.

Impulsivity facets and substance use initiation: A comparison of two models of impulsivity.

Several types of impulsivity have been linked to various substance use outcomes. The UPPS-P framework has received major focus within the field of substance use research. However, this framework is not without limitation. An alternative framework is the Two-Factor Model of impulsivity, which posits that rash impulsivity and reward drive are the central, if not sufficient, domains of impulsivity. Unfortunately, the extant literature is quite limited in terms of work that have directly compared the UPPS-P framework to the Two-Factor Model of impulsivity, particularly in prospective designs focused on the initiation of common, problematic forms of substance use among adolescents (i.e., alcohol and marijuana use). In the current study, the UPPS-P measures were compared to dedicated measures of the Two-Factor Model of impulsivity in a sample of Chilean adolescents who were lifetime abstainers of alcohol or marijuana use at baseline (N = 541) to predict the initiation of use for these substances at a one-year follow-up. Results showed that the Two-Factor Model had superior predictive utility compared to the UPPS-P measures, and only rash impulsivity and reward drive were significant predictors in a multivariate model that simultaneously considered UPPS-P and Two-Factor Model assessments. Overall, the current findings indicate that the Two-Factor Model should be considered to index risk of substance use initiation to guide prevention efforts and highlight the importance of direct comparisons of alternative measurement and theoretical frameworks of impulsivity within the field of substance use research.

Predicting latent classes of drug use among adolescents through parental alcohol use and parental style: a longitudinal study.

PURPOSE: The present study examined the roles of parental alcohol use and parental style as predictors of adolescent patterns of drug use. METHODS: 6391 students in the 7th and 8th grades at 72 Brazilian public schools participated in a three-wave randomized controlled trial to evaluate a school drug-use prevention program. Patterns of drug use were identified through two latent class analyses using measures of the adolescents' past-year drug use. Multinomial logistic regression analyses examined whether parental alcohol use and parenting style at baseline predicted patterns of drug use in waves 2 and 3 of the study after controlling for sociodemographic covariates. RESULTS: In each of the two waves, three latent classes of drug use were identified among the students, defining three different groups of individuals: (1) abstainers/low users, (2) alcohol users/binge drinkers, and (3) polydrug users. First, parenting style (especially monitoring) was the strongest predictor for the prevention of polydrug use among adolescents. Second, occasional alcohol use by parents can act as a central predictor for adolescent alcohol use and binge drinking. Above all, maternal episodes of drunkenness were involved in the predictive models for both drug use classes in both waves. CONCLUSION: Parental alcohol use and parenting style seem to be important predictors of adolescent's likelihood of belonging to different latent classes of drug use. This conclusion may point to the importance of considering the inclusion of parenting skills and parental alcohol use within the scope of adolescents' preventive interventions.

Influence of parental smoking on the use of alcohol and illicit drugs among adolescents / Influência do tabagismo parental no consumo de álcool e drogas ilícitas entre adolescentes

ABSTRACT Objective: To evaluate the association between parental smoking and the use of alcohol and illicit drugs among adolescent children. Methods: A cross-sectional study with 6,264 adolescents (59.7% female) aged between 14 and 19 years. To establish the sample, we used two-stage cluster random sampling. The data on parental smoking and use of cigarettes, alcohol and illicit drugs among adolescents were collected using a questionnaire. Results: Smoking adolescents were more prone to use alcohol (odds ratio − OR: 10.35; 95%CI: 7.85-13.65) and illicit drugs (OR: 11.75; 95%CI: 9.04-15.26) than non-smokers (p<0.001). Adolescents with at least one parent (OR: 1.4; 95%CI: 1.13-1.89) or both parents smoking (OR: 1.6; 95%CI: 1.01-2.67) were more likely to smoke when compared to those having no parents smoking. The adjusted analysis limited to non-smoking adolescents showed a positive association (p<0.05) between parental tobacco use and the use of alcohol (OR: 1.4; 95%CI: 1.23-1.62) and illicit drugs (OR: 1.6; 95%CI: 1.24-2.13), irrespective of age, sex, maternal schooling and place of residence. Conclusion: Parental smoking was associated with the use of alcohol and other illicit drugs by adolescents, even among nonsmokers.

RESUMO Objetivo: Analisar a associação entre tabagismo parental e uso de álcool e drogas ilícitas dos filhos adolescentes. Métodos: Estudo transversal conduzido com 6.264 adolescentes (59,7% meninas) com idade entre 14 e 19 anos. Para estabelecimento da amostra, recorreu-se à amostragem aleatória por conglomerados em dois estágios. Os dados sobre tabagismo dos pais e uso de cigarros, álcool e drogas ilícitas entre os adolescentes foram obtidos por questionário. Resultados: Os adolescentes fumantes eram mais propensos a usar álcool (odds ratio − OR: 10,35; IC95%: 7,85-13,65) e drogas ilícitas (OR: 11,75; IC95%: 9,04-15,26) do que os não fumantes (p<0,001). Os adolescentes que pelo menos um dos pais fumava (OR: 1,4; IC95%: 1,13-1,89) ou os dois fumavam (OR: 1,6; IC95%: 1,01-2,67) tiveram mais chances de fumar quando comparados aos que não tinham pais fumantes. Análise ajustada limitada a adolescentes não fumantes revelou associação positiva (p<0,05) entre o tabagismo dos pais e o consumo de álcool (OR: 1,4; IC95%: 1,23-1,62) e drogas ilícitas (OR: 1,6; IC95%: 1,24-2,13), independentemente de sexo, idade, escolaridade materna e região de moradia. Conclusão: O tabagismo dos pais esteve associado com o consumo de álcool e outras drogas ilícitas em adolescentes, até mesmo entre os não fumantes.

Associação entre fatores sociodemográficos e comportamentos de risco à saúde cardiovascular de adolescentes brasileiros com 13 a 17 anos: dados da Pesquisa Nacional de Saúde do Escolar 2015 / Asociación entre factores sociodemográficos y comportamientos de riesgo a la salud cardiovascular de adolescentes brasileños con 13 a 17 años: datos de la Encuesta Nacional de Salud del Escolar 2015 / Association between socio-demographic factors and cardiovascular health risk behaviors of Brazilian adolescents aged 13 to 17 years: data from the 2015 National School-Based Health Survey

Objetivo: analisar associação entre fatores sociodemográficos e comportamentos de risco à saúde cardiovascular de adolescentes brasileiros com 13-17 anos. Métodos: utilizaram-se dados sobre 10.926 adolescentes entrevistados na Pesquisa Nacional de Saúde do Escolar (PeNSE) 2015 para verificar associações entre variáveis sociodemográficas e consumo de alimentos não saudáveis, atividade física insuficiente e experimentação de bebida alcoólica/cigarro, empregando-se regressão de Poisson. Resultados: verificaram-se associações entre consumo de guloseimas, atividade física insuficiente e experimentação de bebida alcoólica com sexo feminino ([RPa=1,37 - IC95% 1,25;1,50], [RPa=1,32 - IC95% 1,26;1,38] e [RPa=1,05 - IC95% 1,00;1,10]); consumo de refrigerante com sexo masculino (RPa=1,17 - IC95% 1,03;1,31) e maior escolaridade materna (RPa=1,14 - IC95% 1,01;1,31); experimentação de cigarro com sexo masculino (RPa=1,12 - IC95% 1,00;1,25), idade de 16-17 anos (RPa=1,51 - IC95% 1,33;1,72), não morar com pai (RPa=1,36 - IC95% 1,20;1,53) e mãe (RPa=1,25 - IC95% 1,13;1,37). Conclusão: comportamentos de risco à saúde cardiovascular influenciados por características sociodemográficas devem ser considerados na promoção à saúde de adolescentes brasileiros.

Objetivo: analizar asociación entre factores sociodemográficos y comportamientos de riesgo a la salud cardiovascular de adolescentes brasileños con 13 a17 años. Métodos: se utilizaron datos de la Encuesta Nacional de Salud del Escolar (PeNSE) 2015 para verificar asociaciones entre variables sociodemográficas y consumo de alimentos no saludables, actividad física insuficiente y experimentación de bebida alcohólica/cigarrillo, empleándose la regresión de Poisson. Resultados: se verificaron asociaciones entre: consumo de golosinas, actividad física insuficiente y experimentación de bebidas alcohólicas con sexo femenino ([RPa=1,37 - IC95% 1,25;1,50], [RPa=1,32 - IC95% 1,26;1,38] y [RPa=1,05 - IC95% 1,00;1,10]); consumo de refrigerante con sexo masculino (RPa=1,17 - IC95% 1,03;1,31) y mayor escolaridad materna (RPa=1,14 - IC95% 1,01;1,31); experimentación de cigarrillo con sexo masculino (RPa=1,12 - IC95% 1,00;1,25), edad de 16-17 años (RPa=1,51 - IC95% 1,33;1,72), no vivir con padre (RPa=1,36 - IC95% 1,20;1,53) y madre (RPa=1,25 - IC95% 1,13;1,37). Conclusión: los adolescentes brasileños presentan comportamientos de riesgo a la salud cardiovascular influenciados por características sociodemográficas, lo que refuerza la importancia de considerar ese contexto en iniciativas de promoción de la salud.

Objective: to analyze association between sociodemographic factors and cardiovascular health risk behaviors of Brazilian adolescents aged 13-17 years. Methods: we used data on 10,926 adolescents from the 2015 National School-Based Health Survey (PeNSE) to verify associations between socio-demographic variables and consumption of unhealthy foods, insufficient physical activity, and experimentation with alcoholic beverages and cigarettes, using Poisson regression. Results: associations were found between consumption of candies, insufficient physical activity and experimentation with alcoholic beverages and the female sex ([PRa=1.37 - 95%CI 1.25;1.50], [PRa=1.32 - 95%CI 1.26;1.38] and [PRa=1.05 - 95%CI 1.00;1.10]); soda consumption with the male sex (PRa=1.17 - 95%CI 1.03;1.31) and higher maternal schooling (PRa=1.14 - 95%CI 1.01;1.31); cigarette experimentation with the male sex (PRa=1.12 - 95%CI 1.00;1.25), being 16-17 years old (PRa=1.51 - 95%CI 1.33;1.72), not living with father (PRa=1.36 - 95%CI 1.20;1.53) or mother (PRa=1.25 - 95%CI 1.13;1.37). Conclusion: cardiovascular health risk behaviors influenced by sociodemographic characteristics should be taken into consideration in Brazilian adolescent health promotion.

Use of psychoactive substances among Brazilian adolescents and associated factors: National School-based Health Survey, 2015. / Uso de substâncias psicoativas em adolescentes brasileiros e fatores associados: Pesquisa Nacional de Saúde dos Escolares, 2015.

AIM: To analyze the consumption of tobacco, alcohol and illicit drugs among schoolchildren according to demographic factors, family context and mental health. METHODS: We used data from the National School-based Health Survey 2015 and included in the sample 102,301 schoolchildren in the 9th grade. We estimated the prevalence of tobacco and alcohol use in the last 30 days and drug experimentation according to demographic, mental health and family context variables. Then, a bivariate analysis was performed using Pearson's χ2 test and the unadjusted odds ratio (OR) was calculated. Finally, we conducted a multivariate analysis including independent variables with an unadjusted association (p < 0.20), for each outcome, estimating the adjusted OR with a 95% confidence interval. RESULTS: The prevalence of tobacco consumption was 5.6%; alcohol consumption, 23.8%; and drug experimentation, 9.0%. Multivariate analysis has indicated that living with parents, having meals with parents or guardian, and family supervision were associated with lower substance consumption; whereas missing classes without parental consent has increased the chances of substance use. Increased chance of substance use was also associated with white skin color, increasing age, to work, feeling lonely and having insomnia. Not having friends was associated with drug and tobacco use, but this was protective for alcohol consumption. CONCLUSIONS: Family supervision was protective for psychoactive substance use among Brazilian schoolchildren, whereas work, loneliness and insomnia have increased their chances of use.

OBJETIVO: Analisar o uso de substâncias psicoativas (tabaco, álcool e drogas ilícitas) em escolares em relação a fatores sociodemográficos, contexto familiar e saúde mental. MÉTODOS: Foram utilizados dados da amostra de 102.301 escolares do nono ano da Pesquisa Nacional de Saúde do Escolar de 2015. Realizou-se o cálculo da prevalência de uso de tabaco e de álcool nos últimos 30 dias e experimentação de drogas, segundo variáveis sociodemográficas, contexto familiar e saúde mental. Procedeu-se a análise univariada, por teste do χ2 de Pearson e cálculo das odds ratios (OR) não ajustadas. Por fim, realizou-se análise multivariada para cada desfecho com as variáveis que apresentaram associação com os desfechos (p < 0,20), calculando-se as OR ajustadas com intervalo de confiança de 95%. RESULTADOS: A prevalência de uso de tabaco foi de 5,6%; do uso de álcool, 23,8%; e da experimentação de drogas, 9,0%. A análise multivariada apontou que, no contexto familiar, morar com os pais, fazer refeição com pais ou responsável e a supervisão familiar foram associados a menor uso de substâncias; enquanto faltar às aulas sem consentimento dos pais aumentou a chance de uso. Maior chance do uso de substâncias esteve ainda associada a cor branca, aumento da idade, trabalhar, sentir-se solitário e ter insônia. Não ter amigos foi associado com uso de drogas e tabaco, porém foi protetor para o uso de álcool. CONCLUSÕES: A supervisão familiar foi protetora do uso de substâncias psicoativas em escolares brasileiros, enquanto trabalhar, sentir-se solitário e ter insônia aumentaram suas chances de uso.

Parental supervision and alcohol use among Brazilian adolescents: analysis of data from National School-based Health Survey 2015. / Supervisão dos pais e o consumo de álcool por adolescentes brasileiros: análise dos dados da Pesquisa Nacional de Saúde do Escolar de 2015.

OBJECTIVE: To evaluate the relation between parental supervision and sociodemographic factors and alcohol use by Brazilian adolescents. METHODS: This is a cross-sectional study with data from National School-based Health Survey (PeNSE) 2015, which included 16,608 adolescents aged 13 to 17 years, students from Brazilian public and private schools. Variables related to alcohol use, sociodemographic factors and parental supervision were evaluated. In order to analyze the relation between sociodemographic variables, parental supervision and use of alcohol among adolescents, prevalence ratios stratified by sex were used. RESULTS: It was observed that 61.4% of the adolescents had tried alcohol, 27.2% had a drunken episode in their lifetime, 9.3% have had problems with alcohol and 29.3% reported alcohol use in last 30 days. The lack of parental supervision was associated with increased use of alcohol. The proportion of alcohol use was higher for girls, and also among those who were older than 16 years, worked, did not live with one or both parents, and lived in the South, regardless of sex. CONCLUSION: The results showed early alcohol experimentation and occurrence of problems due to its use among Brazilian adolescents. In addition, the lack of monitoring by parents and guardians shows a risk of alcohol use in this age.

OBJETIVO: Avaliar a relação de indicadores de supervisão dos pais e fatores sociodemográficos com o uso de álcool pelos adolescentes brasileiros. MÉTODOS: Trata-se de estudo transversal com dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2015. A amostra foi composta de 16.608 adolescentes de 13 a 17 anos estudantes de escolas públicas e privadas brasileiras. Foram analisadas variáveis relacionadas ao uso de álcool, aos fatores sociodemográficos e aos indicadores de supervisão dos estudantes pelos pais. Foram calculadas razões de prevalência (RPs) para análise das relações existentes entre as variáveis sociodemográficas, de supervisão dos pais e o uso de álcool por adolescentes. As análises foram estratificadas por sexo. RESULTADOS: Encontrou-se que 61,4% dos adolescentes já haviam experimentado bebida alcoólica, 27,2% já tiveram episódio de embriaguez alguma vez na vida, 9,3% já tiveram problemas devido ao uso de álcool e 29,3% relataram uso nos últimos 30 dias. Menores escores de supervisão dos pais se associaram à maior prevalência de uso de álcool, que também foi elevada entre as meninas, os que tinham idade superior a 16 anos, moravam na Região Sul, trabalhavam e não moravam com os pais. CONCLUSÃO: Os resultados obtidos evidenciaram, em adolescentes, a experimentação precoce de bebidas alcoólicas e a ocorrência de problemas devido ao uso da substância. Além disso, a falta de supervisão e acompanhamento mais próximo dos filhos pelos pais e responsáveis aumentou o uso de álcool nessa idade.

The Relationship between Substance Use and Depressive Symptoms among Colombian Adolescents / Relación entre el uso de sustancias y los síntomas depresivos entre adolescentes colombianos

ABSTRACT Objective: To explore the relationship between substance use and depressive symptomatology among adolescents in Colombia. Methods: Adolescents aged 13-19 years from a rural city in Colombia completed the Spanish version of the Alcohol, Smoking and Substance Involvement Screening Test and the Kutcher Adolescent Depression Scale-6 (KADS-6). Results: Regression analyses indicated that gender, having used cannabis, having used sedatives, and having a family member who used illegal drugs were predictive of higher symptom levels of depression according to KADS-6. Conclusion: The results of this study suggested that substance use was associated with depressive symptoms in this sample of Colombian adolescents.

RESUMEN Objetivo: Explorar la relación entre el uso de sustancias y la sintomatologia depresiva entre adolescentes en Colombia. Métodos: Los adolescentes de 13 a 19 años de una ciudad rural en Colombia completaron la versión en español de la Prueba de Detección de Alcohol, Tabaco y Sustancias (ASSIST, en inglés) y la Escala de Depresión pasa Adolescentes de Kutcher-6 (KADS-6, en inglés). Resultados: Los análisis de regresión indicaron que tanto el género, como el haber consumido cannabis, usado sedantes, y tener un miembro de la familia que usó drogas ilegales, fueron predictores de niveles más altos de sintomas depresivos de acuerdo con la escala KADS-6. Conclusión: Los resultados de este estudio sugirieron que el uso de sustancias estaba asociado con sintomas depresivos en esta muestra de adolescentes colombianos.

Sexual behaviors: study in the youth.

OBJECTIVE: To characterize sexual behaviors in a sample of adolescents and youth. METHODS: An analytical descriptive study using a questionnaire about sexual behaviors, adapted from the World Health Organization. It was distributed to students from a Portuguese city aged 14-24 years, during two months. Two age groups were defined: G1 - students aged 14-19 years; G2 - aged 20-24 years. RESULTS: The sample included 2,369 students, 61% females and 70% in G1. The mean age of first sexual intercourse was 16.4±1.8 years; 93% used some contraceptive method in the first sexual intercourse. Out of those who did not use contraception in the first sexual intercourse, 83% were in G1 (p<0.001). Emergency contraception was used at least once by 54% (63% in G2, p<0.001). Among those who had unprotected sexual intercourses, 9% were under the influence of alcohol, 53.6% were female and 53.4% were in G2 (p<0.001). Homosexual contacts occurred in 21% of cases; in that, 62% in G1 and 84% among females (p<0.001). CONCLUSION: The use of contraceptionin the first sexual intercourse was common in our sample. However, the number of adolescents not using any contraceptive method in subsequent sexual intercourses, and the high percentage of them who consider it unnecessary, are a concern. Unprotected sexual intercourses, as well as unplanned intercourses and under influence of alcohol or drugs, especially in the youngest, urge the need for intervention regarding sexual education.

Associations Among Infant Iron Deficiency, Childhood Emotion and Attention Regulation, and Adolescent Problem Behaviors.

This study examined whether iron deficiency (ID) in infancy contributes to problem behaviors in adolescence through its influence on poor regulatory abilities in childhood. Chilean infants (N = 1,116) were studied when there was no national program for iron fortification (1991-1996), resulting in high rates of ID (28%) and iron-deficiency anemia (IDA, 17%). Infants (54% male) were studied at childhood (Mage  = 10 years) and adolescence (Mage  = 14 years). IDA in infancy was related to excessive alcohol use and risky sexual behavior in adolescence through its effect on poor emotion regulation in childhood. Attentional control deficits at age 10 were also related to both infant IDA and heightened risk taking in adolescence. Findings elucidate how poor childhood regulatory abilities associated with infant IDA compromise adjustment in adolescence.
