Abstract

Abstract: We examined body composition in relation to body perception and lifestyle habits in 105 female students. Their body mass index (BMI) was in the standard range, but about 60% of them had a body fat percentage of 28% or more, indicating so-called hidden obesity. In judging physique using BMI, the group with a low body weight had lower body fat percentage, muscle mass, body water content, and basal metabolic rate than the standard and obesity groups. Regarding body perception, there was a false recognition that about 50% were “fat” despite the standard BMI. Furthermore, 90 students in the standard BMI group were divided into two groups according to the body fat percentage and compared; the hidden obesity group had higher actual/ideal body weight and visceral fat level than did the standard group. A comparison of the lifestyle habits of the two groups showed that the percentage of those who exercised 2 to 4 times a week was higher in the standard than hidden obesity group. Based on the above, to have a correct body perception, it is important to make body shape judgments by measuring the body fat percentage in addition to the BMI. In addition, it was suggested that to maintain proper body composition, it is necessary to have correct body perception and exercise twice a week or more.
