Judul: Correlation between Mother's Nutritional Knowledge, Parental Dietary Pattern, and Nutritional Status of Toddlers with Adolescent Mothers
Abstrak: Provinsi Jawa Barat merupakan salah satu provinsi di Indonesia dengan persentase pernikahan usia dini tertinggi. Tingginya angka pernikahan usia dini tersebut menyebabkan banyak terjadinya ibu dengan kehamilan pertama di usia remaja. Psikososial pada remaja putri belum siap untuk menjalankan peran menjadi seorang ibu yang dapat mendorong terjadinya pola asuh penelantaran sehingga anak kurang perhatian dan kurang asupan makanan yang bergizi seimbang.

Penelitian ini dilaksanakan di Kecamatan Gebang, Kabupaten Cirebon. Jumlah subjek penelitian sebanyak 44 baduta berusia 6-24 bulan. Hasil penelitian menunjukkan bahwa terdapat hubungan signifikan positif antara pengetahuan gizi ibu remaja dengan pola asuh makan (p<0,05) dan terdapat hubungan signifikan negatif antara pengetahuan gizi ibu remaja dengan status gizi baduta berdasarkan indeks BB/U dan TB/U (p<0,05)., West Java is one of provinces in Indonesia with highest percentage of early marriage. The high rate of early marriage causes many mothers to have their first pregnancies in their teens. From a psychosocial perspective, female teenagers are generally not ready to assume the role of being a mother which can lead to neglect of parenting so that the child is less attentive and less likely to feed them a balanced and nutrious diet. Lack of mother’s nutritional knowledge will affect inappropriate feeding practices. Good nutritional intake is not only influenced by adequate food availability but is also influenced by good parenting. This study aims to analyze correlation between mother’s nutritional knowledge, parental dietary pattern and nutritional status of toddlers with adolescent mothers. The research design used was a cross sectional study. The research was conducted in Gebang District, Cirebon Regency. The number of research subjects was 44 toddlers aged 6-24 months. The results showed that there was a significant positive correlation between mother’s nutritional knowledge and parental dietary pattern with adolescent mothers (p<0,05) and there was a significant negative correlation between mother’s nutritional knowledge and nutritional status of toddlers based on index of weight/age and height/age with adolescent mothers (p<0,05).
