April2010) di 23 puskesmas menggunakan desain cross sectional dengan jumlah sampel104 orang. Data primer merupakan wawancara data karakteristik ibu, tingkatpengetahuan, kondisi sosio ekonomi, asupan zat gizi serta aktifitas fisik. Datadianalisis menggunakan uji regresi logistik. Proporsi ibu hamil remaja usia 15-19tahun risiko KEK sebesar 56,7%. Terdapat hubungan antara usia menarche, asupanenergi, asupan protein dan aktivitas fisik dengan risiko KEK. Asupan proteinmerupakan faktor dominan setelah dikontrol variabel usia menarche, gynecologicalage (GA), tingkat pendidikan suami, asupan energi dan aktifitas fisik. Ibu hamil usiaremaja dengan asupan protein < 80% AKG berpeluang 13,416 kali risiko KEKdibanding ibu hamil usia remaja dengan asupan protein ≥ 80% AKG. Upayapencegahan risiko KEK dapat dilakukan dengan melakukan intervensi terhadapwanita usia reproduktif sebelum kehamilan termasuk meningkatkan asupan nutriendan meningkatkan berat badan sebelum kehamilan.
