Background: Stunting is a growth impairment resulting from chronic malnutrition condition or prolonged infectious diseases. It may cause growth retardation, low endurance, lack of intelligence and productivity. Stunting prevalence in Indonesia reached 37.2% where Special Region of Yogyakarta reached 27% and Bantul District was 18.08%. Low birth weight babies have a life chance, however, when they survive they are still vulnerable to diseases, growth retardation, and developmental disorders. Statistics showed that 90% low birth weight cases found in developing countries and the mortality rate was 35 times higher in infants with low birth weight compared to infants with normal birth weight. Objectives: To understand the relationship between weight low birth (BBLR) and stunting in children 6-23 month in Sedayu District Bantul Yogyakarta.Methods: This study used observational research with cross-sectional design. The population in this study were parents and children from 6-23 months which were 1217 subjects. The sample used in this study as many as 190 subjects were selected by using proportional probability to size techniques. Data were analyzed by using chi-square test. Results: Bivariate analysis showed that low birth weight infants was significantly related with stunting (OR= 6.16; 95% CI: 3.007-12.656). In other words, children born with low birth weight status had a chance 6.16 times greater to become stunting than the children who birth weight normal Conclusion: There was a relationship between low birth weight infants and stunting in children 6-23 months in Sedayu Subdistrict, Bantul District, Yogyakarta. KEYWORDS: low birth weight, stunting, children aged 6-23 months ABSTRAKLatar belakang: Stunting adalah gangguan pertumbuhan yang terjadi akibat kondisi kekurangan gizi kronis atau penyakit infeksi kronis. Dampak yang ditimbulkan antara lain lambatnya pertumbuhan anak, daya tahan tubuh yang rendah, kurang kecerdasan dan produktivitas yang rendah. Prevalensi balita stunting di Indonesia mencapai 37,2%, sementara di Provinsi Daerah Istimewa Yogyakarta (DIY) sebesar 27%, di Kabupaten Bantul sebesar 18,08%. Bayi BBLR memiliki kesempatan hidup dan ketika bertahan mereka mudah terkena penyakit, retardasi pertumbuhan dan gangguan perkembangan mental. Statistik menunjukan bahwa 90% dari kejadian BBLR didapatkan di negara berkembang dan angka kematian 35 kali lebih tinggi dibandingkan pada bayi dengan bayi berat badan lahir lebih dari 2.500 gram. Tujuan: Untuk mengetahui hubungan antara BBLR dengan kejadian stunting pada anak usia 6-23 bulan di Kecamatan Sedayu Kabupaten Bantul Yogyakarta. Metode: Penelitian ini merupakan penelitian observasional dengan rancangan cross sectional. Populasi dalam penelitian ini adalah orang tua dan anak yang berumur 6-23 bulan yang berjumlah 1217 responden. Sampel dalam penelitian ini berjumlah 190 yang diambil dengan teknik proporsional probability to size yaitu prosedur penarikan sampel dimana peluang...
