Latar Belakang: Stunting adalah gangguan pertumbuhan balita akibat masalah gizi kronis, terutama dalam 1.000 Hari Pertama Kehidupan, ditandai tinggi badan di bawah standar usia (Z-score < -2 SD). Pada 2022, prevalensi stunting di Indonesia 21.6%, masih jauh dari target RPJMN 14% pada 2024. Salah satu faktor yang mempengaruhi stunting adalah pemberian ASI Eksklusif. Tujuan: Untuk mengetahui hubungan pemberian ASI eksklusif dengan kejadian stunting pada balita di wilayah kerja Puskesmas Rafae. Metode: Penelitian ini menggunakan desain studi potong lintang, dengan pengumpulan data primer dan sekunder dilakukan pada bulan Juli 2024. Jumlah sampel 114 balita berusia 12-59 bulan. Kuesioner akan diisi oleh orang tua/wali balita yang berpartisipasi. Sampel akan diambil dengan teknik non-randomized purposive sampling. Hasil: Hasil analisis menunjukkan bahwa anak yang tidak menerima ASI eksklusif memiliki risiko stunting 9.6 kali lebih tinggi (OR = 9.602; p < 0,001) dan anak yang tidak mendapatkan MPASI memiliki risiko 5 kali lebih tinggi (OR = 5.373; p = 0.004). Jarak lahir yang lebih panjang secara signifikan menurunkan risiko stunting (OR = 0.059 dan 0.07; p < 0.05). Usia ibu saat melahirkan dan BBLR tidak signifikan secara statistik, tetapi berpotensi sebagai variabel pengganggu. Kesimpulan: Terdapat hubungan signifikan antara pemberian ASI eksklusif dan kejadian stunting pada balita di Puskesmas Rafae. Selain itu, ditemukan pula hubungan antara jarak kelahiran > 2 tahun, anak tunggal, dan riwayat pemberian MPASI dengan kejadian stunting. / Background: Stunting is a growth disorder in toddlers due to chronic malnutrition problems, especially in the First 1,000 Days of Life, characterized by height below the age standard (Z-score <-2 SD). In 2022, the prevalence of stunting in Indonesia was 21.6%, still far from the RPJMN target of 14% in 2024. One of the factors that influences stunting is the provision of Exclusive Breastfeeding. Objective: To determine the relationship between exclusive breastfeeding and the incidence of stunting in toddlers in the Rafae Health Center work area. Method: This study used a cross-sectional study design, with primary and secondary data collection conducted in July 2024. The sample size was 114 toddlers aged 12-59 months. The questionnaire will be filled out by the parents/guardians of the participating toddlers. The sample will be taken using a non-randomized purposive sampling technique. Result: The results of the analysis showed that children who did not receive exclusive breastfeeding had a 9.6 times higher risk of stunting (OR = 9.602; p < 0.001) and children who did not receive complementary feeding had a 5 times higher risk (OR = 5.373; p = 0.004). Longer birth intervals significantly reduced the risk of stunting (OR = 0.059 and 0.07; p < 0.05). Maternal age at delivery and LBW were not statistically significant, but were potentially confounding variables. Conclusion: There is a significant relationship between exclusive breastfeeding and the incidence of stunting in toddlers at the Rafae Health Center. In addition, a relationship was also found between birth spacing > 2 years, being an only child, and a history of providing complementary feeding with the incidence of stunting.
