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

Objective: To evaluate differences in children's eating behavior as a function of their nutritional status, sex 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, southern Brazil, in 2012. Children's Eating Behaviour Questionnaire (CEBQ) subscales were used to assess eating behaviours: Food Responsiveness (FR), Enjoyment of Food (EF), Desire to Drink (DD), Emotional Overeating (EOE), Emotional Undereating (EUE), Satiety Responsiveness (SR), 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% were normal weight (n = 163), 26% overweight (n = 86), 15% obese (n = 50) and 9.7% severely obese (n = 32). Children with excessive weight showed higher scores on 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.

Conclusions: "Food approach" subscales were positively associated to excessive weight in children. Significant age and gender differences in eating behaviours were not found.
