Chomchai C Background: Adolescent obesity is rapidly becoming a major pubic health concern in Thailand. Factors that contribute to
adolescent obesity are increasingly sedentary behaviors, changes in eating habits and physical activity. Body-image
perception and peer influence are substantial for adolescents. As a result, knowing the obesity-related psychological impacts
in adolescent will be the great benefit for health care providers in taking care of obese adolescents
Objective: The purpose of this study was to investigate the impact of obesity has on the behaviors and attitudes regarding selfperception,
health outlook, and eating behavior in the mildly obese and the moderately-to-severely obese Thai adolescents.
Material and Method: Participants were obese students who were being followed at the school-based Teen Health Clinic on
a regular basis. All participants were followed regularly at their respective school-based Teen Health Clinics. Each participant’s
percent weight for height was calculated by using Thai National Growth charts. Participants were categorized into 2 groups
according to the percent weight for height (% WFH). Those with% WFH below 120% was considered not obese and excluded
from the study. The two participating groups were% WFH of 120-140% who are mildly obese (M-O group) and% WFH of
greater than 140% who are moderately-severely obese (M-S-O group). A 3-part questionnaire was used to assess the impact
of obesity on emotional and psychosocial aspects of each participant, their eating and nutritional attitude and their level of
physical activity.
Results: Of the 5,366 students, grade 7-12 who attended 2 metropolitan Bangkok schools, 678 were diagnosed as overweight
or obese. There were 175 obese students who attended the clinic regularly were asked to participate in this study and there
were 167 adolescents who completed the questionnaires recruited for this study. Both the M-O and M-S-O groups reported
dissatisfaction with their body weight (85.9% and 91.7% respectively) and perceived their need for weight reduction. The
M-S-O groups expressed more concerns to lose their weight for medical reasons than the M-O group (52.1% vs. 35.2%,
p-value < 0.03). Being obese was shown to have more significant impact to their confidence in M-S-O group than the
M-O group (71.9% vs. 50.7%, p < 0.005). The students in M-O group eat lunch regularly otherwise M-S-O group, few of
them, skips lunch meal (100% vs. 93.8%, p < 0.032).
Conclusion: From our study, significant obese adolescents were shown to have poorer self-image with greater prevalence
being shown in the significantly obese group.
