Hubungan Indeks Massa Tubuh (IMT) Dengan Body Image (Citra Tubuh) Pada Remaja di SMAN 06 Pekanbaru

Abstract

Body Mass Index (BMI) status in adolescents is a key indicator for assessing health,

both physically and psychologically. Adolescents with abnormal BMIMsuch as being

overweight or underweight tend to have specific perceptions of their body shape (body

image). Negative body perceptions can affect self-confidence, psychosocial well-being,

and the quality of life of adolescents. This study aims to determine the relationship

between Body Mass Index (BMI) and body image among adolescents at SMAN 06

Pekanbaru. The study employed a quantitative method with a cross-sectional design.

The study population consisted of all 312 tenth-grade students at SMAN 06 Pekanbaru,

with a sample size of 176 respondents selected using purposive sampling. Data were

collected through measurements of weight and height to determine BMI categories, as

well as the completion of the Multidimensional Body-Self Relations Questionnaire

(MBSRQ) to measure body image. Data analysis was performed using univariate and

bivariate methods, employing the Fisher’s Exact test with a 95% confidence level. The

results of the study indicate that the majority of respondents in the underweight and

normal weight categories have a positive body image, whereas respondents in the

overweight, Class I obesity, and Class II obesity categories are more likely to have a

negative body image. The Fisher’s exact test yielded a p-value of 0.000 (p < 0.05),

indicating a significant association between Body Mass Index (BMI) and body image

among adolescents at SMAN 06 Pekanbaru.
