ABSTRACT

The purpose of this study is to determine the correlation of socioeconomic, dietary, and anthropometric-nutritional variables of parents and their children to overweight (including obesity) in schoolchildren in Santa Catarina State, Brazil. This is a transversal study conducted on 4,964, 6 to 10-year-old schoolchildren registered in 345 Santa Catarina elementary schools. The following data were acquired: the children’s current weight and height, birth weight and length, duration of breastfeeding, age at which water, herbal tea and other foods were introduced to their diet; parental income, education level, age, weight and height were also obtained. The prevalence of overweight and obese children were estimated by point and by interval with a 95% confidence; prevalence rates were obtained based on the Poisson model. An hierarchical approach was used, in which variables were adjusted within blocks and included in the model when they presented p<0.05 at the outcome (overweight including obesity). The results indicate that 47.8% of the subjects were male. The prevalence of overweight and obese students was 15.4% (CI95%: 14.4%-16.5%) and 6.1% (CI95%: 5.4%-6.7%) respectively and were statistically similar among sexes and age ranges. BMI values were higher in males and among older children (p<0.05). After adjustment within and among blocks, the variables per capita household income and parents’ BMI values remained associated with overweight (including obesity). Overweight (including obesity) in schoolchildren is associated with a higher per capita household income and parental overweight and obesity.


Este estudo objetivou verificar a associação entre variáveis socioeconômicas, dietéticas, antropométrico-nutricionais dos pais e da criança e a presença de sobrepeso incluindo obesidade, em escolares do Estado de Santa Catarina. Trata-se de um estudo transversal com 4.964 escolares entre 6 a 10 anos matriculados em 345 escolas do ensino fundamental de Santa Catarina. Foram obtidos dados de peso e estatura dos escolares, peso e comprimento ao nascer, tempo de aleitamento materno, idade da introdução de água ou chá e de outros alimentos, renda, escolaridade e idade, peso e estatura dos pais. As prevalências de sobrepeso e obesidade foram estimadas por ponto e por intervalo com 95% de confiança e as razões de prevalência foram obtidas a partir do modelo de Poisson. Foi utilizada a abordagem hierárquica, onde as variáveis foram ajustadas dentro dos blocos e incluídas no modelo quando apresentaram p<0,05 com o desfecho (sobrepeso incluindo obesidade). Os resultados indicam que 47,8% dos participantes pertenciam ao sexo masculino. As prevalências de sobrepeso e obesidade foram, respectivamente, 15,4% (IC95%: 14,4%-16,5%) e 6,1% (IC95%: 5,4%-6,7%), sendo estatisticamente semelhantes entre sexos e categorias de idade. Os valores do IMC foram maiores no sexo masculino e entre as crianças mais velhas (p<0,05). Após ajuste dentro e entre os blocos permaneceram associadas com a presença de sobrepeso incluindo obesidade, as variáveis renda familiar per capita e IMC dos pais. O sobrepeso incluindo obesidade dos escolares está associado à renda familiar per capita mais elevada e ao fato dos pais apresentarem sobrepeso e obesidade.
