Berdasarkan survei survei awal yang dilakukan oleh peneliti menunjukkan bahwa sebanyak 56% siswa SMA di salah satu sekolah swasta di Tangerang menggunakan suplemen makanan. Angka ini ternyata lebih tinggi jika dibandingkan dengan prevalensi penggunaan suplemen makanan di dunia (31%). Dari hal tersebut, peneliti tertarik untuk melakukan penelitian yang bertujuan untuk mengetahui proporsi penggunaan suplemen makanan pada siswa SMA serta menilai hubungan antara status kesehatan dan faktor lainnya dengan konsumsi suplemen makanan. Penelitian ini menggunakan desain penelitian cross sectional yang dilakukan pada bulan April di SMA Islamic Village Tangerang. Sampel yang digunakan sebanyak 135 responden yang dipilih secara systematic random sampling. Konsumsi suplemen makanan merupakan variabel terikat dalam penelitian ini. Sedangkan variabel bebas terdiri dari status gizi (Indeks Massa Tubuh), riwayat si, riwayat penyakit kronis, jenis kelamin, pengetahuan gizi, asupan karbohidrat, asupan protein, konsumsi sayur, konsumsi buah, praktek konsumsi suplemen orang tua, keterpaparan media promosi, dan pengaruh teman sebaya. Instrumen penelitian yang digunakan meliputi kuesioner, form FFQ-SQ, timbangan seca, microtoise, dan food model. Penelitian ini melibatkan analisis univariat dan analisis bivariat berupa uji chi square. Hasil dari penelitian ini menunjukkan proporsi pengguna suplemen makanan pada siswa SMA Islamic Village Tangerang Tahun 2012 sebesar 53,3%. Selain itu, terdapat hubungan yang bermakna antara riwayat penyakit kronis, praktek konsumsi suplemen orang tua, keterpaparan media massa, dan pengaruh teman sebaya dengan konsumsi suplemen makanan. Hubungan yang bermakna antara riwayat penyakit kronis dengan konsumsi suplemen makanan (p value = 0,020) sejalan dengan penelitian yang dilakukan Rock (2007). Hubungan yang bermakna antara praktek konsumsi suplemen orang tua dengan konsumsi suplemen makanan (p value = 0,000) juga didukung dengan penelitian Ramadani (2005). Adanya hubungan antara keterpaparan media promosi dengan konsumsi suplemen makanan (p value = 0,000) juga sejalan dengan penelitian Putri (2004). Sedangkan hubungan yang bermakna antara pengaruh teman sebaya dengan konsumsi suplemen makanan (p value = 0,000) didukung oleh penelitian O’Dea (2003). Dari penelitian ini diketahui bahwa terdapat hubungan antara riwayat penyakit kronis dengan faktor lingkungan sosial dengan konsumsi suplemen makanan. Selain itu, diperoleh saran bagi pihak siswa dan orang tua agar lebih selektif dalam memilih produk suplemen makanan yang sesuai dengan kebutuhannya, serta bagi pihak sekolah dan pihak pemerintah (dinas kesehatan dan pendidikan Kabupaten Tangerang) agar lebih mensosialisasikan informasi terkait gizi kepada masyarakat.
