- Description
- Body composition changes drastically in both males and females during the adolescent years. The changes may have a negative effect on their physical health as well as psychological well-being, with respect to attributes such as self-efficacy. Being either overweight or obese during adolescence has social, economic and psychological consequences, which include low self-efficacy. However, very few international studies and not a single South African study could be found which measured the relationship of anthropometric body composition components, general self-efficacy levels and actual measured body size among adolescents, particularly among rural adolescents. Consequently, the aim of this study was to investigate the relationship between anthropometric body composition components and self efficacy, by conducting a comparison of self-efficacy levels among normal, overweight and obese 12 to 14-year-old rural adolescents in the Eastern Cape Province of South Africa. The sample consisted of boys (n=49) and girls (n=43) between the ages of 12 and 14 years. The body composition components were body weight, stature, body mass index, sum of 3 skinfolds, percentage body fat and hip-to-waist ratio. The sample was also classified into normal, overweight and obese groups, according to body mass index. A self-administered Self-Efficacy Questionnaire for Children (SEQ-C) which was developed by Muris (2001) was used to measure general self-efficacy. Data were analyzed by means of descriptive statistics, the Pearson correlation matrix and Cohen's effect size for significance (Cohen, 1992) and a Mann-Whitney U Test was used to determine statistical differences. Significance was set at p<0.05. Only 17 percent of the participants in the research sample were found to be overweight or obese. Only emotional self-efficacy showed significant (p=0.02) differences between the participants who were classified as having normal weights and the group which comprised the overweight and the obese groups. Overweight and obese boys and girls still had very high levels of self-efficacy, although their body mass index scores were high. Boys scored higher in social self-efficacy and girls in academic self-efficacy. Only girls presented significantly high correlations between body mass index and emotional self-efficacy (r=0.33, p=0.02), total self-efficacy and hip-to-waist ratio (r=0.44, p=0.00), social self-efficacy and hip-towaist ratio (r=0.39, p=0.01) and emotional self-efficacy and hip-to-waist ratio (r=0.33, p=0.02), while boys presented them only with respect to body weight (r=0.31, p=0.02) and stature (r=0.39, p=0.00). The results suggest that a positive relationship exists between body composition, in terms of hip-to-waist ratio, weight and stature, and self-efficacy among South African rural adolescents. However, girls presented significantly strong and positive correlations between hip-to-waist ratio and self-efficacy, whereas boys presented significant, strong and positive correlations between body weight, stature and self-efficacy. Only emotional self-efficacy showed significant differences between normal weight and overweight or obese South African rural adolescents. It seems likely that cultural beliefs may exert an influence on the psychosocial perceptions of adolescents in relation to body size, consequently affecting self efficacy levels.
