Permasalahan kesehatan akibat kurangnya cuci tangan pakai sabun (CTPS) masih menjadi masalah di dunia. CTPS belum banyak diterapkan oleh masyarakat, termasuk di MI Yapimda Jakarta Selatan yang baru saja mendapat intervensi untuk pertama kalinya oleh peneliti. Penelitian dilakukan pada 55 siswa kelas 4 dan 5 selama bulan Mei-Juni 2011 untuk melihat hubungan jenis kelamin, pekerjaan orang tua, suku bangsa orang tua, pengetahuan, sikap, dukungan orang tua, dukungan guru, sanksi sekolah, dan keterjangkauan fasilitas CTPS di sekolah dengan perilaku CTPS. Berdasarkan hasil penelitian, hanya dukungan orang tua yang memiliki hubungan signifikan dengan perilaku CTPS pada siswa MI Yapimda.
