1 KETERKAITAN SUB SISTEM KONSUMSI, UTILISASI BIOLOGIS DAN STATUS GIZI

2 KETERKAITAN SUB SISTEM PANGAN & GIZI Sistem PanganSistem Gizi Subsistem Pangan ProduksiKetersediaanDistribusiKonsumsiStatus Gizi Sub sub sistem 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 Pertumbuha n, daya kerja Gizi kurang / lebih

3 FAKTOR MEMPENGARUHI KONSUMSI PANGAN 1.FAKTOR EKONOMI Permintaan (Demand) 1.Harga pangan 2.Harga pangan lain 3.Pendapatan konsumen 4.Demografi (penduduk) 5.Tingkat kesukaan 6.Qualitas pangan 2. FAKTOR DEMOGRAPI 1.Usia 2.Jenis kelamin 3. SOSIO-BUDAYA Kebudayaan 1.Kebiasaan 2.Pola asuh anak 3.Kepercayaan & tabo 4.Sanitasi & higiene 5.Daya terima & kesukaan 6.Pantangan agama

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

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

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

8 NUTRITIONINFECTION 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 A.Physiological factors (Growth, exercise, pregnancy, and lactation) B.Composition of diet (Prot, Min, Vit) C.Route, Rate and Timing D.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 DRUGSEFFECTSNUTRIENTS INVOLVED NUTRITION CONSIDERATION Cathartics and laxatives Increase GIT motilityVit ADEK, Ca, K, Carotene, fat glucose, phospate CHON- losing K, Mg, Ca, Na and fluid losses Decresed glucose absorption Mineral oil decrease absorption of ADEK DiurecticsInhibits tubulars reabsorption of NaCl, Water maintain N K loss K, Na, Chloride, Ca, Water, Zn, Mg K depletion with concurrent ACTH or stroids Excessive K loss in cardiac patients Urinary loss of Ca, Zn, Mg electrolytes and water soluble vitamins

13 DRUGSEFFECTSNUTRIENTS INVOLVED NUTRITION CONSIDERATION AnalgesicRelieve painFalic acid, Vit D, Ascorbic acid Decrease tissue ascorbic acid Decrase folic acid absorption Decrease gastric & pancreatic secretion Decrease peristalsis & appetite AntacidsDecrease gastric acidity Phosphates, Na, Fe, Thiamine Vitamin deficiency Edema due to increase Na, Fe and Thiamine deficiency AntibioticsInhibit of kill microorganism CHON, Ca, Mg, Fe, Vit K, B12 Inhibited AA absorption & prot systhesis Suppressed appetite Malabsorptiion of vit B12, Ca, Fe, Mg Sysnthesis of Vit decrease lactose malabsorption

14 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
