Perkiraan ada 120 juta kasus pneumonia setiap tahun di seluruh dunia, yangmengakibatkan sebanyak 1,3 juta kematian. Setiap tahun pneumonia selalu menempatiperingkat atas sebagai penyebab kematian bayi dan balita di Indonesia. Penelitian inibertujuan untuk mengetahui faktor- faktor berhubungan dengan kejadian pneumonia padabalita (12-59 bulan) di Provinsi DKI Jakarta. Penelitian menggunakan data sekunder dariRiset Dasar Kesehatan (Riskesdas) tahun 2018. Desain penelitian yang digunakan adalahcross sectional. Hasil penelitian menunjukkan proporsi kejadian pneumonia pada balitaadalah 5,7%. Tidak ada hubungan yang signifikan secara statistik antara karakteristikbalita dan karakteristik ibu dengan kejadian pneumonia. Proporsi pneumonia lebih tinggipada balita berumur 25-59 bulan (OR=1,852), berjenis kelamin laki-laki (OR=1,2),berstatus imunisasi campak lengkap (OR=1,448), berstatus imunisasi DPT-HB-HiBlengkap (OR=1,069), berstatus pemberian vitamin A lengkap (OR=1,189), dan memilikiibu berpendidikan tinggi (OR=1,779).

There is no statistically significant relationship betweentoddler characteristics and mother characteristics with the incidence of pneumonia. Theproportion of pneumonia is higher in toddlers aged 25-59 months (OR = 1.852), male(OR = 1.2), complete measles immunization status (OR = 1,448), complete DPT-HB-HiBimmunization status (OR = 1.069), complete vitamin A status (OR = 1.189), and havehighly educated mothers (OR = 1.779).
