<![CDATA[Stunting occurs due to lack of nutritious food intake that does not meet nutritional needs over a long period of time and repeated infections. Stunting causes obstacles to children's intelligence, reduces productivity and suffers from diseases in adulthood. The purpose of this study was to determine the factors associated with the incidence of stunting in children aged 12-59 months in the Sikumana Health Center Work Area, Kupang City. This type of research was observational analytic with a cross-sectional design, involving 367 toddlers aged 12-59 months in the Sikumana Health Center work area in 2023. The factors studied were history of exclusive breastfeeding, history of complementary feeding of breast milk, history of basic immunization, maternal nutritional knowledge, maternal education, family income and number of family members. Measurement of factors was carried out by filling out questionnaires and interviews. The incidence of stunting was known by measuring body length using a length board, and height using a microtoise. Data were analyzed using the Chi-square test. The results of the study showed that the p-value for each factor was: history of exclusive breastfeeding = 0.002, history of complementary feeding of breast milk = 0.002, history of basic immunization = 0.098, maternal nutritional knowledge = 0.001, maternal education = 0.009, family income = 0.211, and number of family members = 0.023. Based on the results of the analysis, it was concluded that the determinants of the incidence of stunting in children aged 12-59 months in the Sikumana Health Center Work Area were a history of exclusive breastfeeding, a history of complementary feeding, maternal nutritional knowledge, maternal education, and number of family members; with the strongest determinant being maternal nutritional knowledge.Keywords: stunting; children; determinants; nutritional knowledge ABSTRAK Stunting terjadi karena kurangnya asupan makanan bergizi yang tidak sesuai dengan kebutuhan gizi dalam kurun waktu yang lama dan adanya infeksi berulang.

Jenis penelitian ini adalah analitik observasional dengan rancangan cross-sectional, yang melibatkan 367 balita berusia 12-59 bulan di wilayah kerja Puskesmas Sikumana pada tahun 2023. Faktor-faktor yang diteliti yaitu riwayat pemberian air susu ibu eksklusif, riwayat pemberian makanan pendamping air susu ibu, riwayat imunisasi dasar, pengetahuan gizi ibu, pendidikan ibu, pendapatan keluarga dan jumlah anggota keluarga. Pengukuran faktor-faktor dilakukan melalui pengisian kuesioner dan wawancara. Kejadian stunting diketahui dengan pengukuran panjang badan menggunakan length board, dan tinggi badan menggunakan microtoise. Data dianalisis menggunakan uji Chi-square. Hasil penelitian menunjukkan bahwa nilai p untuk masing-masing faktor adalah: riwayat air susu ibu eksklusif = 0,002, riwayat makanan pendamping air susu ibu = 0,002, riwayat imunisasi dasar = 0,098, pengetahuan gizi ibu = 0,001, pendidikan ibu = 0,009, pendapatan keluarga = 0,211, dan jumlah anggota keluarga = 0,023.
