Children's eating behavior: comparison between normal and overweight children from a school in Pelotas, Rio Grande do Sul, Brazil

Abstract

OBJECTIVE: To evaluate differences in children's eating behavior in relation to their nutritional status, gender and age. METHODS: Male and female children aged six to ten years were included. They were recruited from a private school in the city of Pelotas, Rio Grande do Sul, southern Brazil, in 2012. Children´s Eating Behaviour Questionnaire (CEBQ) subscales were used to assess eating behaviors: Food Responsiveness (FR), Enjoyment of Food (EF), Desire to Drink (DD), Emotional Overeating (EOE), Emotional Undereating (EUE), Satiety Responsiveness (SR), Food Fussiness (FF) and Slowness in Eating (SE). Age-adjusted body mass index (BMI) z-scores were calculated according to the WHO recommendations to assess nutritional status. RESULTS: The study sample comprised 335 children aged 87.9±10.4 months and 49.3% had normal weight (n=163), 26% were overweight (n=86), 15% were obese (n=50) and 9.7% were severely obese (n=32). Children with excess weight showed higher scores at the CEBQ subscales associated with ""food approach"" (FR, EF, DD, EOE, p<0.001) and lower scores on two ""food avoidance"" subscales (SR and SE, p<0.001 and p=0.003, respectively) compared to normal weight children. Differences in the eating behavior related to gender and age were not found. CONCLUSIONS: ""Food approach"" subscales were positively associated to excess weight in children, but no associations with gender and age were found.

OBJETIVO: Avaliar diferenças no comportamento alimentar infantil em função do estado nutricional, do sexo e da idade. MÉTODOS: O estudo incluiu crianças na faixa de seis a dez anos, de ambos os sexos, de uma escola privada em Pelotas (RS), em 2012. Para avaliar o comportamento alimentar usaram-se as subescalas do questionário Children's Eating Behaviour Questionnaire (CEBQ): resposta à comida (FR), prazer de comer (EF), desejo de beber (DD), sobreingestão emocional (EOE), subingestão emocional (EUE), resposta à saciedade (SR), seletividade (FF) e ingestão lenta (SE). Avaliou-se o estado nutricional por meio do escore-z do IMC/idade. RESULTADOS: Participaram 335 crianças de 87,9±10,4 meses. Apresentaram eutrofia 49,3% (n=163), sobrepeso 26% (n=86), obesidade 15% (n=50) e obesidade grave 9,7% (n=32). Crianças com excesso de peso tiveram maior pontuação nas subescalas de ""interesse pela comida"" (FR, EF, DD, EOE, p<0,001) e menor pontuação nas subescalas de ""desinteresse pela comida"" (SR e SE, p<0,001 e p=0,003, respectivamente), se comparadas com as crianças com peso adequado. Não foram observadas diferenças no comportamento alimentar segundo sexo e idade. CONCLUSÕES: Observou-se que comportamentos alimentares que refletem ""interesse pela comida"" estão associados positivamente ao excesso de peso, mas não foi encontrada associação com o sexo e a idade da criança.
