Data menunjukkan bahwa angka kejadian penyakit ISPA nasional selalu menunjukkan peningkatan setiap tahun.Tahun 2013 dengan Provinsi Jawa Tengah menempati posisi ketujuh dengan jumlah penderita ISPA terbanyak. Angka kejadian ISPA nonpneumonia selama 2011-2013 di Kota Magelang maupun di Puskesmas Kelurahan Magersari selalu menunjukkan peningkatan dengan sebagian besar penderita adalah balita. Penelitian ini bertujuan untuk mengetahui seberapa besar faktor risiko kualitas lingkungan fisik rumah (jenis lantai, atap, dinding, luas ventilasi, kepadatan hunian) dan pencemaran udara dalam rumah (keberadaan perokok dalam rumah, pengguaan anti nyamuk bakar, bahan bakar memasak dalam rumah)terhadap kejadian ISPA nonpneumonia pada balita di wilayah kerja Puskesmas Magersari, Kota Magelang, Jawa Tengah tahun 2013. Desain penelitian ini adalah case-control dengan masing-masing sampel berjumlah 50 balita. Case adalah balita yang menderita ISPA nonpneumonia dengan diagnosis dokter puskesmas, sedangkan control balita yang didiagnosis tidak menderita ISPA. Ada hubungan yang bermakna antara jenis lantai nilai p 0,000 &OR 15,881 ( 95% CI : 4,949-50,958), jenis atap nilai p 0,000 & OR 13,500 (95% CI 5,087-35,830), jenis dinding nilai p 0,000 &OR 17,484 ( 95% CI 6,314-48,415), kepadatan hunian, nilai p 0,000 & OR 12,250 (95% CI 4,652-32,258), keberadaan perokok dalam rumah nilai p 0,003 &OR 4,205 ((95% CI 1,692-10,448) dan penggunaan bahan bakar memasak nilai p 0,000 & OR 11,294 (95% CI 2,435-52,379).
