ABSTRACT
The purpose of the study was to investigate the prevalence of overweight and obesity among young Brazilian aged 5 to 19 years through systematic review and metaanalysis of data available in the literature. An electronic search was conducted for articles in the MedLine/PubMed, Scopus, Web of Science, Scielo e Lilacs published from 2000 to 2018 were selected using predefined inclusion/exclusion criteria. Measures of heterogeneity and variability were calculated, and random effect model were used to estimate pooled prevalence rates. Forest-plots graphs were generated by sex and age. Meta-regression models were fitted to identify possible sources of heterogeneity in the prevalence estimates. Of the 1,002 articles initially identified 26 met the inclusion criteria. In children (5-9 years) the pooled prevalence rates of verweight were 16.2% (95%CI 13.2-19.3; Q=411.7, p<0.001; I2=97.8%) in girls and 14.4% (95%CI 11.5-17.3; Q=403.9, p<0.001; I2=97.7%) in boys. Obesity, 9.2% (95%CI 5.9-12.3; Q=1111.7, p<0.001; I2=99.2%) and 9.0% (95%CI 5.5-12.5; Q=1413.1, p<0.001; I2=99.4%), respectively. Regarding adolescents (10-19 years), in girls 16.4% (95%CI 15.1-17.7; Q=245.6, p<0.001; I2=92.3%) for overweight and 6.2% (95%CI 4.9-7.5; Q=842.9, p<0.001; I2=97.7%) for obesity. In boys, 15.3% (95%CI 13.4-17.1; Q=493.7, p<0.001; I2=96.2%) and 6.7% (95%CI 5.0-8.5; Q=1200.4, p<0.001; I2=98.4%), respectively. Geographic region, year of data collection and diagnostic criteria had a significant impact on the heterogeneity of the prevalence of overweight and obesity. The review identified increasing trends in the prevalence rates, highlighting the urgent need to promote healthy lifestyles from the young ages, in order to effectively address the presence of excess body weight.
RESUMO
O objetivo do estudo foi investigar a prevalência de sobrepeso e obesidade em jovens brasileiros entre 5 e 19 anos através de revisão sistemática e metanálise de dados disponibilizadas na literatura. Foi realizada busca eletrônica nas bases de dados MedLine/PubMed, Scopus, Web of Science, Scielo e Lilacs publicados de 2000 a 2018, utilizando critérios de inclusão/ gerados por sexo e idade. Modelos de metarregressão foram ajustados para identificar exclusão pré-definidos. Medidas de heterogeneidade e variabilidade foram calculadas e modelos de efeito aleatório foram usados para estimar taxas de prevalência global. Gráficos forest-plots foram possíveis fontes de heterogeneidade. Dos 1002 estudos identificados inicialmente 26 atenderam os critérios de inclusão. Nas crianças (5-9 anos) as taxas de prevalência global de sobrepeso foram equivalentes a 16,2% (IC95% 13,2-19,3; Q=411,7, p<0,001; I2=97,8%) nas moças e 14,4% (IC95% 11,5-17,3; Q=403,9, p<0,001; I2=97,7%) nos rapazes. No caso da obesidade, 9,2% (IC95% 5,9-12,3; Q=1111,7, p < 0,001; I2=99,2%) e 9,0% (IC95% 5,5-12,5; Q=1413,1, p<0,001; I2=99,4%), respectivamente. Referente aos adolescentes (10-19 anos), nas moças 16,4% (IC95% 15,1-17,7; Q=245,6, p<0,001; I2=92,3%) para sobrepeso e 6,2% (IC95% 4,9-7,5; Q=842,9, p<0,001; I2=97,7%) para obesidade. Nos rapazes, 15,3% (IC95% 13,4-17,1; Q=493,7, p<0,001; I2=96,2%) e 6,7% (IC95% 5,0-8,5; Q=1200,4, p<0,001; I2=98,4%), respectivamente. Região geográfica, ano de coleta dos dados e critérios diagnósticos impactaram significativamente na heterogeneidade das prevalências. Foram identificadas tendências crescentes nas taxas de prevalência, ressaltando a necessidade urgente de promover estilos de vida saudáveis desde as idades jovens, a fim de abordar com eficácia a presença do excesso de peso corporal.
