Background: The health benefits of regular physical activity are well documented. However, there are few studies associating this practice with sedentary behavior and cardiovascular risk in adolescents. Objectives: To evaluate physical activity levels and sedentary behavior and their associations with cardiovascular risk using the Pathobiological Determinants of Atherosclerosis in Youth (PDAY) score Methods: A cross-sectional study carried out in state-owned public schools in Campina Grande, PB, Brazil, with 576 adolescents aged 15 to 19 years, investigating socioeconomic; demographic; lifestyle; and clinical variables. Data were collected using a validated form covering anthropometry data; blood pressure measurements; and laboratory tests. Data were analyzed using descriptive statistics, Pearson' s chi-square test, and binomial logistic regression using SPSS 22.0 and adopting a 95% confidence interval. Results: Mean age was 16.8 years.The majority of the adolescents were female (66.8%); non-white (78.7%); and belonged to socioeconomic classes C, D and E (69.1%). The prevalence rates of sedentary behavior and physical inactivity were 78.1% and 60.2%, respectively. According to the PDAY score, 10.4% of adolescents were at high cardiovascular risk and 31.8% and 57.8% were at intermediate risk and low risk, respectively. PDAY scores were associated with sex and abdominal adiposity. Conclusions: It was found that abdominal fat and being male were important cardiovascular risk factors in adolescents. Considering that modifiable risk factors were present, preventive measures aimed at lifestyle changes are essential.
persistent MetS was associated with obesity, HDL-c and LDL-c, but not with the PDAY score.
Medicinal plants: traditional healers' indications for the treatment of wounds Plantas medicinales: indicación de herboristas para el tratamiento de heridas RESUMO Objetivo: Analisar as indicações e o conhecimento de raizeiros quanto ao uso de plantas medicinais para o tratamento de feridas. Métodos: Estudo quantitativo, de caráter descritivo, realizado com 32 raizeiros do município de Campina Grande-PB, no período de novembro de 2012 a março de 2013. Utilizou-se um questionário estruturado, contendo 21 questões fechadas e abertas, referentes a variáveis sociodemográficas, informações sobre as espécies vegetais indicadas para o tratamento de feridas, aquisição de conhecimentos sobre o assunto e comercialização das plantas. Realizou-se análise descritiva dos dados com cálculo de frequências absolutas e relativas. Resultados: Dos 40 comerciantes de plantas convidados a participar da pesquisa, 32 (75%) consentiram a entrevista, dos quais 75% (n=24) do sexo feminino, 50% (n=16) possuíam 60 anos ou mais, 25% (n=8) residiam na zona rural, e apenas 18,75% (n=6) cultivavam as ervas que comercializavam. Neste ramo, 87,5% (n=28) trabalhavam há mais de cinco anos, sendo a transmissão familiar através das gerações a forma mais comum de aquisição de conhecimentos (87,5%; n=28). Um total de 18 plantas foi citado pelos raizeiros, onde o cajueiro roxo foi o mais indicado (87,5%; n=28), seguido pelo barbatimão (81,25%; n=26) e pela quixaba (50%; n=16). Conclusão: Este estudo deixa em aberta a questão sobre o nível de conhecimento popular de raizeiros investigados acerca do uso de plantas medicinais no tratamento de feridas, visto que o mesmo advém de fonte familiar sem cientificidade, com imprecisa indicação terapêutica.
