The relationship between body shape perception and health behaviors among Korean normal-weight adolescents using...

Inappropriate adolescent health behavior can be influenced by the negative impact of physical and mental health promotion. Obesity influences subjective improper weight perception. This study aimed to verify Korean normal-weight adolescents' subjective experience of weight control, mental health, physical activity, and subjective status based on their body mass index (BMI). As a result, efforts to control weight appeared less in normal-weight boys. Thin girls were less likely to carry out 60 min of physical activity 7 or 5 days per a week. Obese boys were less likely to carry out vigorous physical activity 3 days per a week. Normal-weight girls were less likely to practice muscular strength training 3 days per a week. Thin boys and thing girls were less likely to practice regular physical activity, and less likely to practice at the rate stipulated in the sedentary behavior guideline. In conclusion, boys and girls with inappropriate weight perception reported feeling stressed and depressed, and reported subjective sleep fulfillment, perceived subjective happiness, and perceived subjective health.
