Resumo(s)
O presente estudo pretende averiguar, numa amostra de 70 mulheres com um Índice de
Massa Corporal (IMC) superior a 30kg/m², os comportamentos alimentares, nomeadamente à
ingestão emocional, ingestão externa e restrição alimentar, avaliados pelo Questionário
Holandês do Comportamento Alimentar (Q.H.C.A.). Pretende ainda explorar a associação do
IMC e à existência ou não de um problema psicológico. Além disso, também se comparou o
IMC entre diferentes grupos com características sócio-demográficas e de saúde divergentes.
Conclui-se que, nesta amostra, um maior IMC não está associado ao comportamento
alimentar, ou seja, à ingestão emocional (r=.036; p=.769), à ingestão externa (r=.120; p=.324)
e à restrição alimentar (r=-.036; p=.766).
Este estudo constata diferenças significativas entre mulheres com e sem um problema
psicológico no que concerne à ingestão emocional (t(67)=-2.494; p=.015), verificando-se que
as mulheres que apresentam um problema psicológico têm mais comportamentos de ingestão
emocional (M=3.12). Contudo, não se encontraram diferenças estatisticamente significativas
entre mulheres com e sem problemas psicológicos em relação à ingestão externa (t(67)=-.682;
p=.498) e também à restrição alimentar (t(67)=.479; p=.633).
Conclui-se, deste modo, que o IMC das mulheres desta amostra não está associado a
uma maior frequência de determinados comportamentos alimentares, constatando-se
igualmente uma ausência de diferenças entre mulheres com e sem um problema psicológico.
Verificaram-se apenas associações estatisticamente significativas em relação à ingestão
emocional.
ABSTRACT: This study aims at exploring the eating behaviours such as emotional eating, external eating and restrained eating in a sample of 70 women with a body mass index (BMI) higher than 30kg/m2, using the Dutch Eating Behaviour Questionnaire (D.E.B.Q). It also explores the association between BMI and the existence of a psychological problem and compares the BMI between groups with different socio-demographic and health characteristics. In this sample a higher level of BMI is not associated to the eating behaviours such as emotional eating (r=.036; p=.769), external eating (r=.120; p=.324) and restrained eating (r=- .036; p=.766). There are significant differences between women with and without a psychological problem regarding the emotional eating (t(67)=-2.494; p=.015) where the women who have some kind of psychological problem have higher levels of emotional eating behaviours (M=3.12). No significant differences were found between women with or without psychological problems concerning external eating (t(67)=-.682; p=.498) and restrained eating (t(67)=.479; p=.633). We conclude that the BMI from women of this sample is not associated to a higher frequency of some eating behaviours and no differences were found between women with or without psychological problems. Significant associations were found only for emotional eating.
