Meningkatnya angka gizi lebih pada remaja disebabkan oleh tingginya konsumsi junk food di kalangan remaja, selain itu konsumsi makanan berserat menunjukkan angka yang rendah. Faktor yang menjadi peran dalam kebiasaan konsumsi makanan remaja adalah pengetahuan gizi remaja.
Tujuan: Penelitian ini bertujuan untuk mengetahui hubungan antara pengetahuan gizi, kebiasaan konsumsi junk food, dan makanan berserat terhadap status gizi Siswa SMA N 1 Salaman.
Metode: Desain penelitian ini menggunakan cross sectional, populasi adalah siswa kelas XI MIPA, dengan sampel 65 siswa, yang diambil menggunakan teknik consecutive sampling. Instrumen penelitian berupa kuesioner, FFQ semi kuantitatif, timbangan badan, dan microtoise. Analisis statistik yang digunakan adalah uji korelasi Gamma.
Hasil: Penelitian menunjukkan 90,8% responden berstatus gizi baik, 81,5% responden memiliki pengetahuan yang baik, konsumsi junk food tergolong sering sebanyak 47,7%, dan 36,9% responden telah memenuhi kebutuhan serat. Hasil uji statistik menunjukkan hubungan pengetahuan gizi dengan status gizi (p=0,939), hubungan konsumsi junk food dengan status gizi (p=0,007), serta hubungan konsumsi makanan berserat dengan status gizi (p=0,010).
Kesimpulan: Adapun hasil penelitian menujukkan tidak terdapat hubungan yang sigifikan antara pengetahuan gizi dengan status gizi, namun terdapat hubungan yang signifikan antara kebiasaan konsumsi junk food dengan status gizi, serta konsumsi makanan berserat dengan status gizi.
