Abstrak: Skripsi ini membahas riwayat penyakit, asupan protein dan faktor-faktor yang berhubungan dengan status gizi pada peserta posyandu lansia. Penelitian ini bersifat kuantitatif dengan desain cross sectional dan jumlah sampel 112 orang. Sampel diambil dengan kriteria umur 45-79 tahun yang menetap di Kecamatan Grogol Petamburan Jakarta Barat. Data Karakteristik (umur, jenis kelamin, pendidikan, pekerjaan), pengetahuan, sikap, dan perilaku gizi seimbang, riwayat penyakit, pola konsumsi (asupan energi, protein, lemak) didapatkan melalui wawancara dengan kuesioner. Sedangkan data status gizi dengan indeks massa tubuh diperoleh dengan pengukuran antropometri. Analisa hubungan antara variabel independen dengan variabel dependen menggunakan uji chi square.Hasil penelitian menunjukkan proporsi responden yang mengalami gizi lebih sebesar 50% dan gizi kurang sebesar 6.3%. Dari hasil analisa bivariat diketahui adanya hubungan bermakna antara riwayat penyakit dan asupan protein dengan status gizi peserta posyandu lansia (p<0.05). Sementara data karakteristik (umur, jenis kelamin, pendidikan, pekerjaan), pengetahuan, sikap, dan perilaku gizi seimbang, pola konsumsi (asupan energi, dan lemak) tidak menunjukkan adanya hubungan yang bermakna dengan status gizi (p>0.05). dari hasil penelitian dapat disimpulkan bahwa peserta posyandu lansia di Kecamatan Grogol Petamburan mengalami masalah gizi ganda. Untuk itu perlu diadakan penyuluhan gizi seimbang secara berkala dan pemantauan status gizi guna mempertahankan IMT normal.

There were a significant association between the historical of disease and protein intake with the nutritional status of the elderly posyandu participants (p <0.05). While the data characteristics (age, sex, education, working status), knowledge, attitudes, behaviors of balanced nutrition, and the pattern of energy, and fat intake showed no significant association with nutritional status (p> 0.05).
