  • Moderate malnutrition contributes more to the overall disease burden than severe, as it affects many more children, even if the risk of death is lower (8). But existing prevention programmes are imperfect, especially in poorest countries or in countries undergoing an emergency crisis, and moderate plus severe malnutrition (as underweight) persists at around 25%, only falling slowly. According to recent National Family Health Survey (1.6) and UNICEF Reports (1.7), 46% of preschool children and 30% of adults in India suffer from moderate and severe grades of protein-calorie malnutrition as judged by anthropometric indicators. Currently, India is in nutrition transition with 10% rural adults and 20% urban adults suffering from overnutrition leading to an emerging double burden of malnutrition (1.8). The first step in this potential transformation came with development of new therapeutic diets. Previously, high-energy milk products had been used, even when appetite was good enough for the child to take non-liquid foods. Ready-to-use therapeutic foods (RUTF) were developed as an alternative, in the form of energy-dense pastes or biscuits containing no water so they do not support bacterial growth (which is a major drawback of milk-based liquid diets). These were shown to be efficacious in obtaining rapid weight gain (14, 15), and furthermore can be used in the community. Addition of adapted mineral and vitamin supplement to the local diet seems also to increase the efficacy of programmes based on the use of locally available nutrient rich foods, but this approach requires further research to determine its effectiveness (17)

Malnutrition Malnutrition Presentation Transcript

  • MALNUTRITION Dr. Sunil Pal Singh.C
  • MALNUTRITION1.Magnitude of malnutrition2. Dimensions of malnutrition3. Measurements of malnutrition4. Prevention and control.
  • MALNUTRITIONIs defined as a pathological state resulting from an absolute or relative deficiency or excess of one or more essential nutrients.
  • MAGNITUDE OF PROBLEMIndia – one fifth population (230 million people ) is undernourished, (The State of Food Insecurity in the World, FAO, 2008)Global Hunger Index - India ranks 94th out of 119countries. (2/3rd of this score is attributable to its high child malnutrition rate)Change in the state of food and nutrition insecurity in India was main cause of rise in number of hungry persons in South Asia (FAO, 2004).
  • MAGNITUDE OF PROBLEM- CONTD. NFHS-3 Survey :56% women are Anemic 30% are low birth weight (LBW) babies47% children are underweight.
  • CAUSES OF DEATHS AMONG <5 YEAR CHILDREN IN DEVELOPING COUNTRIES Malaria * 8% Measles *Others 5% 29% Diarrhoea * 12% Malnutrition* * Approximately 60% 70% of all childhood deaths are associated Pneumonia * with one or more 20% of these fivePerinatal conditions 22% HIV/AIDS 4% Source: WHO 2002; Lancet-2003

  • NUTRITIONAL PROBLEMS1.Undernutrition:Macro-nutr. : Low birth weight (LBW) Protein energy malnutrition (PEM) Chronic Energy Deficiency (CED)Micro-nutr. : Vitamin A deficiency (VAD) Iron deficiency anemia (IDA) Iodine deficiency disorder (IDD) etc.2.Overnutrition: Overweight and Obesity Diet related chronic diseases Fluorosis etc.
  • 3. IMBALANCE Imbalance can result if energy potential of fat in diet exceed 30% of total input, that of saturated fatty acids exceeds 10% or that of carbohydrates falls below 50%.

  • INDICATORS OF NUTRITIONAL STATUS 1. Direct Indicators: -- Nutritional Anthropometry -- Clinical Assessment -- Bio-chemical Estimations -- Biophysical Tests 2.Indirect Indicators: -- Dietary assessment -- Prevalence of Morbidities -- Vital statistics 3.In addition, Secondary Data: -- Socio-economic -- Demographic -- Environmental

  • 2.DIET SURVEYS
  • TYPES OF DIET SURVEYS  Food balance sheets  Family diet survey  Individual diet survey  Food frequency  Institutional diet surveys
  • WEIGHMENT DIET SURVEY (Households)The method involves weighing of edible portion of raw ingredients before cooking of food. Duration of the survey could be for one, three or 7 consecutive days.
  • 24 HRS RECALL METHOD (OR) ORALQUESTIONNAIRE (OR) INDIVIDUAL DIETSURVEYThe raw equivalents of different foods consumed byan individual is computed as follows: Raw quantity of a givenfood stuff in the preparation Volume of cooked XTotal volume of food cooked Food consumed
  • INSTITUTIONAL LEVEL DIET SURVEY (Hostels, Industrial Canteens, Jails and Orphanages)The raw ingredients, total cooked foods and individualplate servings are weighed. Individual intake of foods &nutrients are computed.Merits : Better accuracyLimitation : Time consuming
  • Institutional level Diet Survey (Hostels, Industrial Canteens, Jails and Orphanages)Food stock registers are verified for a week.The average intake/caput/day= (stocks at the beginningof week - stocks at the end of week) / Total number ofinmates partaking x 7 days.
