Penyakit diare merupakan penyakit yang terjadi hampir di seluruh belahan dunia, dengan tingkat dehidrasi berat dan angka kematian paling tinggi terjadi pada bayi dan balita. Angka kesakitan dan kematian pada balita akibat diare di Indonesia masih tinggi. Prevalensi diare pada balita di Kabupaten Temanggung tiga tahun terakhir terus meningkat, begitu pula di UPT Puskesmas Kandangan. Penelitian ini bertujuan untuk mengetahui hubungan sanitasi dasar, lingkungan fisik rumah, faktor ibu, dan karakteristik balita dengan kejadian diare pada balita. Desain penelitian menggunakan studi kasus kontrol dengan sampel 100 kasus dan 100 kontrol, dengan populasi seluruh balita yang berusia 12 sampai 59 bulan. Analisis data dilakukan secara univariat, bivariat, dan multivariat. Hasil penelitian menunjukkan ada hubungan bermakna antara sarana air bersih (6,25; 3,04-12,83), sarana jamban keluarga (5,06; 2,76-9,27), sarana pembuangan air limbah (2,53;1,42-4,52), sarana pembuangan sampah (2,55; 1,27-5,09), perilaku ibu (4,32;2,39-7,81), jenis lantai rumah (3,45; 1,66-7,20), dan kepadatan lalat (2,71; 1,28- 5,73), dengan kejadian diare pada balita. Variabel yang diprediksi paling dominan berhubungan dengan kejadian diare pada balita adalah sarana air bersih (2,90;1,26-6,67).
