Body adiposity, behavior pattern and stress in adolescents

Resumen

The objective of this study was to analyze the relationship between the body adiposity index (BAI), behavior pattern and stress of adolescents starting their courses at the Federal Technical School in Santa Catarina, Brazil. 170 subjects participated in the study, comprising 94 male subjects (mean age =14.9±1.0) and 76 female subjects (mean age =14.7±0.7). In addition to measuring body mass (BM) and stature (ST) in order to characterize the sample, adiposity index was calculated from triciptal and subscapular skinfolds and their sums. The data related to behavior patterns and stress were obtained using a Behavior Inventory and a Stress Symptom Inventory. It was observed, from analysis of the results, that BM and ST were within the percentage range of normality, according to the standard of Santo André, SP. When BAI for male and female subjects was compared, it was higher for female subjects. The sum of skinfolds for both male and female subjects was within the ideal range. BAI was also observed above the ideal level in 24.5% of the male subjects and in 44.7% of the female subjects. In relation to behavior pattern, most of the subjects (59.1% of males and 64.1% of females) exhibited Type “A”. Female subjects exhibited more vulnerability to stress (55.2%) when compared to male subjects (29.8%). The stress stage with the highest number of subjects was the resistance stage, with 53.9% and 29.8% for female and male subjects, respectively. The results failed to demonstrate an association between BAI and behavior pattern, between BAI and stress or between behavior pattern and stress. It can be concluded that behavior pattern and stress do not infl uence BAI in adolescents.
