Abstrak: Penelitian ini bertujuan untuk menganalisis pengetahuan gizi, kebiasaan makan, konsumsi minuman manis, dan tingkat kecukupan energi dan zat gizi dengan status gizi pada mahasiswa IPB University. Desain penelitian ini adalah cross sectional study dengan melibatkan 46 mahasiswa berstatus gizi normal dan 46 mahasiswa berstatus gizi gemuk/obesitas. Sebagian subjek memperoleh tingkat pengetahuan gizi rendah (50%), skor kebiasaan makan rendah (81,5%), asupan energi minuman manis sedang (45,7%), frekuensi konsumsi minuman manis sering (75%), dan tingkat kecukupan energi (76,1%), protein (68,5%), lemak (67,4%), dan karbohidrat (78,3%) kurang. Terdapat perbedaan yang signifikan antara kelompok status gizi normal dan gemuk pada variabel asupan energi minuman manis dan frekuensi konsumsi minuman manis (p<0,05). Uji korelasi menunjukkan terdapat hubungan yang signifikan antara frekuensi konsumsi minuman manis, tingkat kecukupan protein dan lemak dengan status gizi (p<0,05). Hasil uji regresi menunjukkan secara keseluruhan terdapat pengaruh antara frekuensi konsumsi minuman manis terhadap status gizi., This study aims to analyze the nutritional knowledge, eating habits, consumption of sweetened beverages, energy and nutrients adequacy level with the nutritional status of IPB University students.
