Anemia masih menjadi masalah kesehatan masyarakat yang perlu mendapat perhatian.Rematri merupakan kelompok rentan. Selain kondisinya sedang dalam masapertumbuhan juga risiko dari menstruasi yang dialaminya. Padahal rematri adalah calonibu sehingga upaya dini intervensi gizi harus dilakukan. Program suplementasi TTDdilakukan untuk mencegah dan menanggulangi anemia serta meningkatkan status besirematri meskipun tidak selalu berhasil karena berbagai faktor. Tujuan penelitian iniuntuk membuktikan dukungan guru sebagai faktor dominan yang berhubungan denganperubahan kadar Hb rematri penerima program. Penelitian ini dilakukan dengan designcrossectional di 2 SMP penerima program di Kota Bekasi dengan sampel 175 rematri.Data perubahan kadar Hb diperoleh dari selisih pengukuran Hb sebelum dan setelahsuplementasi TTD berjalan 10 minggu yang merupakan data sekunder (telah lolos etik).Data lainnya yaitu data dukungan sekolah, karakteristik rematri, pola konsumsi dankarakteristik Ibu diperoleh melalui wawancara pengisian kuisioner. Hasil penelitianmendapatkan bahwa suplementasi TTD efektif meningkatkan kadar Hb rematri (p=0,005). Analisa regresi linear ganda mendapatkan hasil bahwa dukungan gurumerupakan faktor dominan yang berhubungan dengan perubahan kadar Hb. Hal inimembuktikan bahwa penuntasan intervensi gizi spesifik memerlukan upaya sensitif darisektor non kesehatan. Sehingga disarankan meningkatkan kolaborasi lintas sektor dalampelaksanaan program kesehatan khususnya program suplementasi TTD berbasissekolah.Kata kunci: anemia, rematri, suplementasi TTD berbasis sekolah, dukungan guru,perubahan Hb
