Abstrak Tuberkulosis (TBC) mengakibatkan penurunan asupan dan malabsorbsi nutrien serta metabolisme tubuh berubah sehingga terjadi massa otot dan lemak menurun akibat mekanisme malnutrisi dari energi protein. Malnutrisi pada TBC berpengaruh terhadap prognosis dan tingkat kematian. Peningkatan produksi IFNl- γ dan IL-6, TNF α menghambat dari aktivitas Lipo Protein Lipase (LPL) dijaringan lemak. Enzim LPL berperan dalam proses bersihan trigliserida. Peningkatan ini meningkatkan trigliserida sehingga proses sintesis lemak menurun dan proses lipolisis lemak meningkat di jaringan. Tujuan penelitian ini menganalisis hubungan trigliserida dan status gizi pada klien TBC. Metode penelitian ini korelasi analitik dengan pendekatan cross-sectional, sampel 25 orang, dengan uji korelasi Pearson-Product Moment. Hasil penelitian status gizi dibawah normal 56%, normal 40% dan kelebihan berat badan 4%. Kadar Trigliserida normal 84%, trigliserida tinggi 16%. Kesimpulan ada hubungan antara kadar trigliserida dan status gizi yakni r hitung sebesar 0,5: r tabel = 0,396 sehingga r hitung > r tabel dengan korelasi positif.Kata Kunci : Trigliserida, Status Gizi, Tuberkulosis.AbstractTuberculosis(TB) resulting the decreasing of nutrient intake and malabsorbsi as well as changing the metabolism of the body. The wasthing are decreased protein energy. Malnutrition on TB affects the prognosis of the treatment and death rates. The increase TNF α will inhibit the enzyme activity of Lipoprotein Lipase (LPL) in the fat tissue. LPL enzyme plays a role in cleavage process of triglycerides. This research was to analyze the relationship of triglycerides and nutrition status on the client with tuberculosis. The design was cross-sectional approach. The respondents were gathered from 25 newly TB patients. The analyzed using Pearson Product-Moment correlation. The results showed 56% respondents undernutrition, and normal 40% and over nutrition 4%. Most triglyceride level of the respondent were normal (84). The concluded was a relationship between triglycerides and the nutritional status with a positive correlation ( P value 0,396).Keywords : Triglycerides, Nutritional Status, Tuberculosis
