摘要: Childhood obesity is increasing globally, and Poland is no exception. Studies indicate that relationship between obesity and psychological well-being is a complex issue and this needs further research. The objective of the present cross sectional study was to analyze the relationship between some temperament components and fatness among children in two developmental periods, approximately before and after adolescence. Participants included 122 children aged 11 years (57 boys and 65 girls), and 153 adolescents aged 17 years (64 boys and 89 girls) from 6 primary and 4 secondary schools in Wrocław, Poland. Height, weight, triceps-, subscapular and abdominal skinfold thicknesses were measured. Temperament was assessed by a questionnaire of Buss and Plomin (1984) in two versions: EAS-C for children completed by parents and EAS-D for youth and adults. Physical activity (PAL) was also assessed by a questionnaire. Mean, median and standard deviation (SD) were calculated and Student's t tests were performed to test for significance of differences between groups. Chi squared (χ2) statistic was used to test the significance of differences in frequencies. Analyses of covariance (ANCOVA) were performed to show the effect of the social-psychological factors on fatness. Controlling for socioeconomic status and physical activity level, activity, as a component of temperament had a significant effect on body fatness. The only component of temperament, which significantly influenced level of fatness in girls, was emotionality. These relationships differed according to sex and the two age groups concerned.
