Hubungan Tingkat Pengetahuan, Sikap tentang Gizi Seimbang, dan Tingkat Stres dengan Indeks Massa Tubuh pada Remaja

Background: Adolescence is an age group that is vulnerable to nutritional
problems due to the biological, psychological, and social changes that occur.
Adolescents' nutritional status can be determined by their daily nutrient intake,
which is influenced by various factors, such as knowledge level, attitudes about
balanced nutrition, and stress levels.
Objective: This study aimed to determine the relationship between the level of
knowledge, attitudes toward balanced nutrition, and stress levels with Body Mass
Index (BMI) among adolescents.
Methods: This study used a quantitative design with a cross-sectional approach.
The sample consisted of 40 adolescent respondents from SMA Nurul Amal
Palembang, using a total sampling technique in grades 10, 11, and 12. Data were
collected through questionnaires on knowledge, attitudes towards balanced
nutrition, stress levels, and BMI measurements. Data analysis was performed
using univariate and bivariate methods using Kendall's tau-b test.
Results: The results showed that most respondents were male 52.5% with an
average age of 16.70 years. The majority of respondents had normal nutritional
status 65%. Most respondents had a low level of balanced nutrition knowledge
80%, moderate attitudes toward balanced nutrition 50%, and moderate stress
levels 85%. Bivariate analysis indicated no significant relationship between the
level of knowledge and BMI p = 0.527, attitudes toward balanced nutrition and
BMI p = 0.591, or stress levels and BMI p = 0.722.
Conclusion: This study concludes that the level of knowledge, attitudes toward
balanced nutrition, and stress levels are not significantly associated with BMI
among adolescents.
Recommendation: Further studies are recommended to involve larger sample
sizes and to examine other factors influencing adolescent BMI, accompanied by
institutional support for balanced nutrition education.
