  1. KETERKAITAN SUB SISTEM KONSUMSI, UTILISASI BIOLOGIS DAN STATUS GIZI

  2. KETERKAITAN SUB SISTEM PANGAN & GIZI Sistem Pangan Sistem Gizi Subsistem Pangan Produksi Ketersediaan Distribusi Konsumsi Status Gizi • Menghasilkan • Dinamika industri & penangan pasca panen : • Menyiapkan & mengolah • Mengawetkan • Mengemas • Mengubah bentuk • Cadangan • Impor • Ekspor • Akses fisik& ekonomi • Statbilitas harga • Keragaman • Keamanan • Jumlah • Mutu gizi • Individu • Keluarga • Masyarakat • Gejala klinik / sub klinik • Pertumbuhan, daya kerja • Gizi kurang / lebih Sub sub sistem

  3. FAKTOR MEMPENGARUHI KONSUMSI PANGAN • FAKTOR EKONOMI 3. SOSIO-BUDAYA • Permintaan (Demand) • Harga pangan • Harga pangan lain • Pendapatan konsumen • Demografi (penduduk) • Tingkat kesukaan • Qualitas pangan • Kebudayaan • Kebiasaan • Pola asuh anak • Kepercayaan & tabo • Sanitasi & higiene • Daya terima & kesukaan • Pantangan agama 2. FAKTOR DEMOGRAPI • Usia • Jenis kelamin

  4. Variabel Gizi Kurang terkait utilisasi biologis • Life stage where malnutrition occurs • Length of malnutrition period • Type of nutrient deficiency • Severity of nutrient deficiency

  5. Lymphoid % of Adult Size Brain & Head Reproductive General Growth of 4 types of body tissue (Harris JA, et al, 1930)

  6. INFECTION & MALNUTRITION • PEM : Peningkatan rawan thd infeksi Tendensi kearah > infeksi • VAD : Campak Penurunan immune Peningkatan peny. Diare Peningkatan ISPA

  7. RELATIONSHIP INFECTION & MALNUTRITION Catabolisme, Urinary N2 Anorexia, Vomiting Malabsorbtion Protien loss in gut INFECTION NUTRITIONAL DEFICIENCY IMMUNOSUPPRESSION Protein synthesis Cell regeneration Cell mediated immunity Antibody respon Mucosal immunity Phagocyte dysfunction Inflammatory response

  8. NUTRITION INFECTION IMMUNOCOMPETENCE

  9. INTERELASI UTILISASI BIOLOGIS, LINGKUNGAN DAN STATUS GIZI ?

  10. Perspective on Environmental Health • Role of environmental health • Host – Agent Interactions - Agent factors - Host factors - Environmental factors

  11. THE EFFECT OF ENVIRONMENTAL HAZARDS ON NUTRITION • Physiological factors (Growth, exercise, pregnancy, and lactation) • Composition of diet (Prot, Min, Vit) • Route, Rate and Timing • Mechanisms of disease Increase utilization of nutrients Malnutrition Impaired ability to activate a nutrient Abnormally large loser of nutrients Impaired catabolic or excretory pathways Hyper absorbtion Drugs Effect on nutrition

  12. STRATEGIES TO IMPROVES BIOLOGICAL UTILIZATION • Environmental sanitation & proper waste disposal • Better housing conditions • Improvement drinking water • Increase & improvement of health facilities • Disease prevention & cure • Micronutrient supply programme • Childcare & breast feeding programme • Food fortification • Health & nutrition education • Reduction of family size • Food protection & safety policies
