Prevalence of alcohol and tobacco use among Brazilian adolescents: a systematic review

OBJECTIVE To analyze alcohol and tobacco use among Brazilian adolescents and identify higher-risk subgroups. METHODS A systematic review of the literature was conducted. Searches were performed using four databases (LILACS, MEDLINE /PubMed, Web of Science, and Google Scholar), specialized websites and the references cited in retrieved articles. The search was done in English and Portuguese and there was no limit on the year of publication (up to June 2011). From the search, 59 studies met all the inclusion criteria: to involve Brazilian adolescents aged 10-19 years; to assess the prevalence of alcohol and/or tobacco use; to use questionnaires or structured interviews to measure the variables of interest; and to be a school or population-based study that used methodological procedures to ensure representativeness of the target population (i.e. random sampling). RESULTS The prevalence of current alcohol use (at the time of the investigation or in the previous month) ranged from 23.0% to 67.7%. The mean prevalence was 34.9% (reflecting the central trend of the estimates found in the studies). The prevalence of current tobacco use ranged from 2.4% to 22.0%, and the mean prevalence was 9.3%. A large proportion of the studies estimated prevalences of frequent alcohol use (66.7%) and heavy alcohol use (36.8%) of more than 10%. However, most studies found prevalences of frequent and heavy tobacco use of less than 10%. The Brazilian literature has highlighted that environmental factors (religiosity, working conditions, and substance use among family and friends) and psychosocial factors (such as conflicts with parents and feelings of negativeness and loneliness) are associated with the tobacco and alcohol use among adolescents. CONCLUSIONS The results suggest that consumption of alcohol and tobacco among adolescents has reached alarming prevalences in various localities in Brazil. Since unhealthy behavior tends to continue from adolescence into adulthood, public policies aimed towards reducing alcohol and tobacco use among Brazilians over the medium and long terms may direct young people and the subgroups at higher risk towards such behavior.OBJETIVO: Analisar o uso de alcool e tabaco em adolescentes brasileiros e identificar os subgrupos de maior risco. METODOS: Foi realizada revisao sistematica da literatura. A busca dos artigos foi feita em quatro bases de dados (LILACS, MEDLINE/PubMed, Web of Science e Google Scholar), websites especializados e referencias dos artigos selecionados. Foram selecionadas referencias em ingles e portugues, sem limites para ano de publicacao (ate junho de 2011), das quais foram incluidos 59 artigos que atenderam aos criterios de inclusao: envolver adolescentes brasileiros de dez a 19 anos de idade; avaliar a prevalencia do uso de alcool e/ou de tabaco; usar questionarios ou entrevistas estruturadas para mensurar as variaveis de interesse; ser um estudo populacional ou de base escolar que adotou procedimentos metodologicos para garantir a representatividade da populacao alvo (isto e, amostra aleatoria). RESULTADOS: A prevalencia de uso atual de alcool (uso na epoca da pesquisa ou no mes anterior) variou de 23,0% a 67,7%. A prevalencia media (refletindo uma tendencia central das estimativas encontradas nos estudos) de uso atual de alcool foi de 34,9%. A prevalencia de uso atual de tabaco variou de 2,4% a 22,0%, com uma prevalencia media de 9,3%. Grande parte dos estudos estimou prevalencias superiores a 10% para o uso frequente (66,7%) e pesado (36,8%) de alcool; a maioria deles estimou prevalencias menores de 10% para o uso frequente e pesado de tabaco. A literatura nacional tem destacado a associacao de fatores ambientais (religiosidade, condicao de trabalho e uso de substâncias entre os amigos e parentes) e psicossociais (como conflitos com pais e sentimentos negativos e de solidao) com o uso de alcool e tabaco entre os adolescentes. CONCLUSOES: Os resultados sugerem que o consumo de alcool e tabaco entre adolescentes tem atingido alarmantes prevalencias em varias localidades do Brasil. Como habitos nao saudaveis tendem a continuar da adolescencia ate a vida adulta, politicas publicas que visam a reducao do uso de alcool e de tabaco na populacao brasileira a medio e longo prazos podem direcionar a populacao jovem e os subgrupos de maior risco a esses comportamentos.

Epidemiology of physical inactivity, sedentary behaviors, and unhealthy eating habits among brazilian adolescents a systematic review

This systematic review analyzed the prevalence of physical inactivity, sedentary behaviors and unhealthy eating habits among Brazilian adolescents. Searches were conducted in five databases (Lilacs, SciELO, Medline, Web of Science, and Google Scholar) and in the references cited in the articles retrieved. The literature search yielded 5,872 potentially relevant titles and a total of 69 studies met all the inclusion criteria. The risk behavior most often evaluated was physical inactivity (48/69; 69.6%), and its prevalence rate ranged from 2.3% to 93.5%. Twenty-eight studies estimated the prevalence of physical inactivity at over 50%. Most studies observed the prevalence of greater physical inactivity among girls. The prevalence of sedentary behaviors (lengthy screen time or TV use) was also frequently over 50%. Several variables were used to identify unhealthy eating habits, and some criteria/studies have indicated unhealthy eating habit estimates at close to 100% among adolescents. In conclusion, the estimates of these risk behaviors among Brazilians adolescents were very close to or even greater than those found in developed countries in several studies analyzed in this review.

Condições de saúde e variáveis sociodemográficas associadas à qualidade de vida em idosas de um programa de atividade física de Curitiba, Paraná, Sul do Brasil

O presente estudo teve como objetivo analisar a associacao entre variaveis sociodemograficas e condicoes de saude com os dominios da qualidade de vida em idosas participantes do programa Idoso em Movimento.

Fatores de risco à saúde cardiovascular em escolaresda Tríplice Fronteira

This study identified cardiovascular risk factors (CRF) in students from Tri-Border Region: Argentina, Brazil and Paraguay. Study participants were 1.183 adolescents of both sexes, ages from 15 to 18 years, who completed a questionnaire to identify the CRF. The proportion of adolescents with four or more CRF was 65.2%. Brazilian male adolescents had the highest prevalence of insufficiently active (78.3%), while the low consumption of vegetables (39.4%) and high time in sedentary activities (83.1%) were higher in Argentinean male adolescents. Paraguayan female adolescents had the highest proportion of insufficiently active (83.0%), while the high time in TV and media, low consumption of fruit, alcohol consumption and the clustering of four or more CRF were higher in Argentinean female adolescents (38.3%, 92.5%, 59.7% and 69.2%, respectively). These results may contribute to policies of healthy lifestyle promotion in the Tri-Border Region.
