ABSTRACT Objective There is evidence demonstrating that cardiovascular diseases (CVD) manifesting during adulthood result from an intense interaction among risk factors that may have originated during childhood and adolescence. To compare the prevalence and clustering of cardiovascular risk factors in Brazilian schoolchildren with a 15-year interval between samples. Subjects and methods A cross-sectional analysis based on the scores for cardiovascular risk factors was used to investigate 1,232 Brazilian schoolchildren of both sexes aged 12 to 18 years. The data of 596 schoolchildren of the 2000 sample were compared to those of 636 schoolchildren of the 2015 sample. Results The prevalence of physical inactivity and abdominal obesity increased exponentially in both sexes from 2000 to 2015. The score for the clustering of cardiovascular risk factors showed that in 2000 the adolescents were exposed to 1 cardiovascular risk factor (31.7%), while in 2015 the greatest percentage was assigned to the category of 3 or more cardiovascular risk factors (34.9%), p < 0.001. Conclusion The present results demonstrate a high prevalence of exposure to health risk behaviors of the adolescents studied over time. Considering the presence of modifiable risk factors, preventive measures regarding life style are essential.

RACIONAL: Nos últimos anos, apesar do Sistema Único de Saúde Brasileiro - SUS - apresentar avanços relacionados à organização e ampliação das ações voltadas à prevenção e ao tratamento da obesidade, existe demanda reprimida de operações no país. Mesmo com evidências favoráveis à operação por via laparoscópica, o SUS só permite o procedimento por via laparotômica. OBJETIVOS: 1) Estimar se os cirurgiões bariátricos apoiariam eventual incorporação da operação por via laparoscópica no SUS; 2) se haveria incremento no número total de operações caso houvesse esta nova opção de via de acesso; e 3) como seria a redistribuição da oferta de operações pelas duas vias. MÉTODOS: Com o método Delphi, foi construído um painel de especialistas, em que cirurgiões bariátricos responderam um questionário estruturado previamente desenvolvido para esse fim. Foram realizadas duas rodadas, no intuito de melhor consenso. RESULTADOS: Dos 45 cirurgiões que estiveram presentes no evento nacional, 30 (66,7%) participaram do questionário Delphi, o que correspondeu à primeira rodada do estudo. Na segunda, e última rodada, dos 30 respondentes da primeira etapa, 22 (48,9%) cirurgiões responderam. Mediante a possibilidade de incorporação da via laparoscópica no SUS, aproximadamente 95% dos cirurgiões manifestaram interesse em realizá-la. Caso a operação por laparoscopia fosse incorporada no SUS, haveria incremento médio no número de operações na ordem de 25%; nesta nova configuração, a oferta de procedimentos cirúrgicos estaria distribuída da seguinte forma: 62,5% por laparoscopia e 37,5% por laparotomia. CONCLUSÃO: 1) Houve preferência pela via laparoscópica; 2) haveria incremento no número de operações comparado ao modelo atual em que apenas a via laparotômica está disponível aos usuários do sistema público; e 3) a distribuição em relação ao tipo de procedimento seria de 62,5% por laparoscopia e 37,5% por laparotomia.

BACKGROUND: Although Brazilian National Public Health System (BNPHS) has presented advances regarding the treatment for obesity in the last years, there is a repressed demand for bariatric surgeries in the country. Despite favorable evidences to laparoscopy, the BNPHS only performs this procedure via laparotomy. AIM: 1) Estimate whether bariatric surgeons would support the idea of incorporating laparoscopic surgery in the BNPHS; 2) If there would be an increase in the total number of surgeries performed; 3) As well as how BNPHS would redistribute both procedures. METHODS: A panel of bariatric surgeons was built. Two rounds to answer the structured Delphi questionnaire were performed. RESULTS: From the 45 bariatric surgeons recruited, 30 (66.7%) participated in the first round. For the second (the last) round, from the 30 surgeons who answered the first round, 22 (48.9%) answered the questionnaire. Considering the possibility that BNPHS incorporated laparoscopic surgery, 95% of surgeons were interested in performing it. Therefore, in case laparoscopic surgery was incorporated by the BNPHS there would be an average increase of 25% in the number of surgeries and they would be distributed as follows: 62.5% via laparoscopy and 37.5% via laparotomy. CONCLUSION: 1) There was a preference by laparoscopy; 2) would increase the number of operations compared to the current model in which only the laparotomy is available to users of the public system; and 3) the distribution in relation to the type of procedure would be 62.5% and 37.5% for laparoscopy laparotomy.
