Judul: Pengetahuan, Sikap, Dan Praktek Pemberian Asi Serta Status Gizi Bayi Usia 4-12 Bulan Di Perdesaan Dan Perkotaan
Abstrak: Exclusive breastfeeding rates in Indonesia is still low. Some studies indicated that low mothers' nutritional knowledge and attitude is the cause of low exclusive breastfeeding practice. The main aim of this study was to compare breastfeeding knowledge, attitude, practice and infants nutritional status between rural and urban areas. In this cross-sectional study, Desa Jayabakti, Kabupaten Sukabumi represents rural area, while Kelurahan Kedung Jaya, Kota Bogor represents urban area. Samples were 31 mothers-infants in each area who were selected by simple cluster sampling method. The differences between two areas were analyzed with the independent t-test, chi-square test, and Fisher's exact test. The correlation between variables were analyzed with rank Spearman. The result of this study showed that mother's knowledge and attitude of nutrition, especially about exclusive breastfeeding, was higher in urban than in rural area. There were differences in mothers' knowledge and attitude between rural and urban areas (p<0.05). Exclusive breastfeeding in rural area practiced by 41.9%, which is higher than in urban area (25.8%). Nevertheless, there was no statistical difference in exclusive breastfeeding practice between rural and urban areas (p>0.05). Breastfeeding practices which statistically difference in rural and urban areas were the introduction of colostrum status and brastfeeding time (p<0.05). Early initiation of breastfeeding was associated with exclusive berastfeeding practice in urban area (p<0.05), but none of the variables were associated with exclusive breastfeeding practice in rural area (p>0.05). Furthermore, exclusive breastfeeding practice was not associated with 4-12 months infants nutritional status (p>0.05). Mothers' family should be targeted as target of audience in breastfeeding promotion.

Judul: Nutritional Status, Breastfeeding Knowledge, and Breastfeeding Practice in Cirebon Regency
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan status gizi ibu (asupan zat gizi dan indeks massa tubuh) dan pengetahuan ASI dengan praktik menyusui bayi usia 0–6 bulan di Kabupaten Cirebon. Desain penelitian ini adalah cross sectional study dengan jumlah subjek sebanyak 44 orang. Data yang digunakan merupakan data sekunder. Penelitian berlokasi di tiga desa di Kecamatan Gegesik, Kabupaten Cirebon yang merupakan lokus stunting. Sebanyak 47,7% subjek memiliki status gizi normal dan 29,5% subjek memiliki status gizi obesitas. Sebagian besar subjek memiliki tingkat kecukupan energi dan zat gizi yang belum mencapai kebutuhan harian. Sebanyak 63,6% subjek memiliki pengetahuan tentang ASI yang baik dan 43,2% subjek memiliki praktik menyusui yang kurang sesuai. Tidak terdapat hubungan signifikan antara tingkat kecukupan energi dan zat gizi ibu dengan status gizi bayi (p>0,05). Tidak terdapat hubungan signifikan antara karakteristik, status gizi, dan pengetahuan ibu mengenai pemberian ASI dengan praktik menyusui (p>0,05)., The purpose of this study is to analyze the relationship between maternal nutritional status (nutrient intake and body mass index) and breastfeeding knowledge with breastfeeding practices for infants aged 0-6 months in Cirebon Regency.
