Background: Adolescents are susceptible to nutritional status issues, both undernutrition, and over-nutrition, becoming a public health concern promptly. There were 912 junior and high-school adolescents who were obese and 249 high-school adolescents who had low body mass index (BMI) in Samarinda City. During the COVID-19 pandemic, adolescents experienced changes in sleep duration, and many adolescents were skipping breakfast. Sleep duration and breakfast can affect the nutritional condition of adolescents. Objectives: The purpose of this study was to determine the association between sleep duration, breakfast routine and BMI in Samarinda, Indonesian adolescents during COVID-19 pandemic.Materials and Methods: A total of 340 adolescents was sampled and assessed using a cross-sectional technique to ascertain their sleep duration, breakfast routine, and nutritional status. Nutritional status was classified based on BMI-for-age and z-value BMI. The amount of sleep duration was calculated by the average wake time and sleep time. Breakfast routine was obtained from seven days of breakfast before 9 am. Then, using multivariate analyses were tested for sleep duration, BMI z-value, breakfast routine, and nutritional status.Results: This study revealed that 68.5% had good nutrition, with an average sleep duration of 8 hours (65.9%) and irregular breakfast (59.1%). Nutritional status was significantly influenced by breakfast routine (p=0.044), gender (p<0.001), and mother’s employment (p<0.001). A cubic association was found between sleep duration and BMI (p=0.045); and a significant association between breakfast routines and BMI, independent from age, gender, ethnicity, school.Conclusion: Adolescents must consider their sleep duration and the frequency and composition of their breakfast. Future study in the longitudinal study is needed to explore in more detail.

Remaja awal memiliki kecenderungan untuk mengkonsumsi sarapan dalam komposisi yang tidak lengkap berdasarkan konsep gizi seimbang. Komposisi yang tidak lengkap dapat menyebabkan tidak terpenuhinya asupan gizi harian remaja yang berimpilkasi terhadap gangguan gizi maupun kesehatan. Tujuan penelitian ini adalah untuk mengetahui gambaran perilaku sarapan siswa-siswi salah satu SMP swasta unggulan di Kota Samarinda yang terdiri dari komposisi menu sarapan serta waktu sarapan serta menilai hubungan antara komposisi menu dengan status gizi remaja.
