Kondisi kamar asrama pesantren dapat memicu timbulnya berbagai agen penyebab penyakit ISPA. Penelitian ini bertujuan untuk menganalisis faktor lingkungan dan perilaku yang berhubungan dengan kejadian ISPA pada santri di Pondok Pesantren ?X? yang berlokasi di Provinsi Jawa Timur menggunakan desain studi cross sectional. Sebanyak 90 santri sebagai sampel penelitian dipilih sesuai kriteria inklusi yaitu bertempat tinggal minimal enam bulan di kamar asrama dan kriteria eksklusi yaitu sedang mengalami penyakit pernapasan tuberculosis (TBC). Pengumpulan data dilakukan menggunakan kuesioner Penyakit Berbasis Lingkungan dengan delapan pertanyaan terkait kejadian ISPA, kondisi lingkungan kamar asrama (kelembaban, luas ventilasi, kepadatan hunian) dan perilaku (mencuci tangan, olahraga, konsumsi vitamin C) yang diisi oleh para santri dibawah bimbingan guru yang telah diberikan arahan terkait pengisian kuesioner. Hasil penelitian menunjukkan sebanyak 43,3% santri di Pondok Pesantren ?X? mengalami ISPA, seluruh kamar asrama dalam kondisi yang tidak memenuhi syarat, dan mayoritas santri telah telah menerapkan perilaku hidup bersih dan sehat dalam pencegahan ISPA dengan baik. Secara statistik, ditemukan adanya hubungan signifikan pada perilaku olahraga teratur terhadap kejadian ISPA (p=0,017), sementara kepadatan hunian, kelembaban, perilaku mencuci tangan dengan air dan sabun, dan perilaku konsumsi vitamin C tidak memiliki hubungan yang signifikan terhadap kejadian ISPA.
