Tinggi badan seseorang dipengaruhi berbagai faktor mulai dari masa kehamilan sampai remaja. Penelitian ini bertujuan untuk mengetahui faktor dominan yang berhubungan dengan TB/U pada remaja perempuan usia 15-17 tahun. Penelitian ini menggunakan desain studi cross-sectional yang dilakukan terhadap 135 siswi kelas X di SMA Negeri 2 Depok pada bulan April-Mei 2015. Pengumpulan data dilakukan dengan pengukuran tinggi badan dan kuesioner yang diisi sendiri oleh responden. Uji statistik yang digunakan adalah analisis univariat, analisis bivariat (uji chi-square), dan analisis multivariat (uji regresi logistik ganda).
Hasil penelitian menunjukkan terdapat 17% responden yang termasuk pendek (TB/U <2 SD). Terdapat hubungan yang bermakna antara berat lahir (pvalue = 0,015), panjang lahir (p-value = 0,001), frekuensi konsumsi sumber protein hewani (p-value = 0,036), frekuensi konsumsi sumber protein nabati (p-value = 0,043), dan tinggi badan ibu (p-value = 0,036) dengan TB/U remaja perempuan. Hasil analisis multivariat menunjukkan panjang lahir sebagai faktor dominan terhadap TB/U remaja perempuan, setelah dikontrol variabel tinggi badan ibu, tinggi badan ayah, berat lahir, frekuensi konsumsi sumber protein hewani, dan frekuensi konsumsi sumber protein nabati.
