ABSTRAK
Penelitian ini bertujuan untuk mempelajari pengaruh usia kawin pertama terhadap perilaku pemberian nutrisi pada anak usia 0-23 bulan menggunakan data SDKI 2012. Berdasarkan tinjauan literatur, variabel usia kawin pertama diduga mengalami masalah endogenitas sehingga usia kawin pertama diprediksi terlebih dahulu menggunakan regresi OLS. Hasil analisis model perilaku pemberian nutrisi pada anak usia 0-23 bulan menggunakan regresi logistik biner menunjukkan bahwa usia kawin pertama berpengaruh negatif terhadap pemberian ASI eksklusif dan terus ASI, tetapi berpengaruh positif terhadap keragaman MPASI.

ABSTRACT
This research aims to study the effect of age at first marriage on their infant and young child feeding behavior using the Indonesian Demographic and Health Survey IDHS 2012 data. Based on literature review, variable age at first marriage is suspected to suffer from endogeneity, thus this variable is predicted using OLS regression in the first stage. The results of infant and young child feeding behavior using the binary logistic regression show that age at first marriage has a negative effect on exclusive breastfeeding and continued breastfeeding and a positive effect on complementary feeding.
