Area of Science:

  • Adolescent health
  • Psychology
  • Public health

Background:

  • Adolescent body image and weight perception are critical for psychological well-being.
  • Accurate assessment of weight status is essential for health interventions.
  • Previous research suggests gender differences in body image perception.

Purpose of the Study:

  • To investigate the relationship between body mass index (BMI) and perceived weight status in adolescents.
  • To examine the influence of perceived weight status and BMI on adolescent self-concept.
  • To identify predictors of perceived overweight status and positive self-concept among teenagers.

Main Methods:

  • Utilized data from the High School and Beyond (HSB) study (N=33,196 adolescents).
  • Calculated body mass index (BMI) from self-reported height and weight.
  • Employed logistic and ordinary least squares regression to analyze perception of overweight status and self-concept index.

Main Results:

  • Higher mean BMI correlated with perceived overweight status, but significant discrepancies exist.
  • Body mass index (BMI) and female gender were strong predictors of perceiving oneself as overweight.
  • Perception of normal weight, lower BMI, and male gender predicted positive self-concept.

Conclusions:

  • A substantial number of adolescent females inaccurately perceive themselves as overweight.
  • Males demonstrate more accurate weight perception compared to females.
  • Weight perception significantly influences adolescent self-concept, with implications for mental health.
