Hubungan Pengetahuan Ibu Mengenai Gizi dengan Kepatuhan PMT pada Balita Berat Badan Kurang

Absract. Underweight in children under five remains a concern; in Bandung City (2023) 7,866 children were classified as underweight (8.34%), and Andir District increased from 5.66% (2022) to 7.76% (2023).  The effectiveness of supplementary feeding (PMT) depends on mothers’ nutrition knowledge and adherence. An analytic cross-sectional study was conducted in the Babatan Primary Health Center catchment area (Ciroyom and Kebon Jeruk) during September–November 2025, involving 70 mothers of underweight children.  Associations between nutrition knowledge and PMT adherence were tested using Chi-square. Most mothers were adherent to PMT (78.6%).  Nutrition knowledge was good (54.3%), fair (30.0%), and poor (15.7%); maternal knowledge was significantly associated with PMT adherence (p=0.012). Non-adherence mainly involved forgetting to provide PMT when traveling and reducing portions without cadre supervision because the child disliked the menu. Strengthened nutrition counseling, routine monitoring, and periodic evaluation are recommended to improve PMT adherence. Abstrak. Masalah berat badan kurang (underweight) pada balita masih menjadi perhatian; di Kota Bandung tahun 2023 tercatat 7.866 balita underweight (8,34%) dan di Kecamatan Andir meningkat dari 5,66% (2022) menjadi 7,76% (2023).  Efektivitas program Pemberian Makanan Tambahan (PMT) dipengaruhi pengetahuan gizi ibu dan kepatuhan pelaksanaannya. Studi analitik observasional dengan desain cross-sectional di wilayah kerja Puskesmas Babatan (Kelurahan Ciroyom dan Kebon Jeruk) pada September hingga November 2025, melibatkan 70 ibu balita berat badan kurang.  Hubungan pengetahuan gizi dan kepatuhan PMT dianalisis menggunakan uji Chi-square. Kepatuhan ibu mayoritas patuh (78,6%).  Pengetahuan gizi kategori baik 54,3%, cukup 30,0%, kurang 15,7%; terdapat hubungan bermakna pengetahuan gizi dengan kepatuhan PMT (p=0,012). Ketidakpatuhan terutama karena lupa membawa/memberikan PMT saat bepergian serta mengurangi porsi tanpa sepengetahuan kader karena balita tidak menyukai menu. Temuan mendukung pentingnya penguatan edukasi gizi, pemantauan, dan evaluasi berkala untuk meningkatkan kepatuhan PMT.
