Abstract

The purpose of this study was to obtain information related to life style characteristics, school achievement and snacking behaviors among underweight and overweight adolescents in Ulsan area. The survey was carried out by self-questionnaires with 464 adolescents (333 underweight and 131 overweight). The results were as follows: Average BMI of the subjects was 19.81±3.10 kg/m² which was normal range, but average BMI of underweight and overweight were 16.90±1.19 kg/m² and 25.38±2.16 kg/m² respectively. The 49.5% of underweight and 94.7% of overweight students have correct perception about their body image. In the sleeping time, 58.9% of underweight and 66.4% of overweight students go to bed after PM 12 o'clock. In the regularity of eating breakfast, 68.5% of underweight and 67.9% of overweight students skipping breakfast at least 5 times per week. 32.6% of the subjects had snack once or more a day. Underweight students had more frequently ate snack than overweight students. The criteria of choosing snack were taste (77.4%), nutrition (9.3%), and price (6.3%). Food as snack they frequently had fruits, milk & milk products, cookies in order. Underweight students had more dodkboki & sundae, candy & chocolate and cake & bread than overweight students, although overweight students had more milk & yogurt than underweight students. The group who had a higher school record, they significantly had more fruits, milk & milk products (p < 0.01) and had not less nutritious foods (p < 0.001). This study may provide basic information on weight status, sleeping and snacking behaviors of adolescents. Therefore they should have nutrition education program to improve their life style and snacking patterns for underweight and overweight adolescents toward healthy weight.
