NATIONAL NUTRITION MONITORING BUREAU NATIONAL INSTITUTE OF NUTRITION Indian Council of Medical Research HYDERABAD - 500 007. INDIA 2000 Nutrition monitoring is the measurement of the changes over time in the nutritional status of a population or a specific group of individuals WHO, 1984 The paucity of reliable and comparable data from all parts of the country is a definite obstacle towards a realistic and disaggregated problem definition. This calls for a national-wide monitoring system. To achieve this, it is necessary to restructure and strengthen the existing National Nutrition Monitoring Bureau (NNMB) and to develop a mechanism for generating nation-wide disaggregated data… National Nutrition Policy, Govt. of India, 1993 Undernutrition continues to be a widespread problem in India, despite significant improvement in food production and advancement in science during the last fifty years, since Indian independence. The National and the State governments have been implementing a number of poverty alleviation programmes for the overall socioeconomic development of the community and several nutrition programmes to mitigate the sufferings of the vast multitudes of the population at risk. The Government of India’s National Nutrition Policy, apart from setting nutrition goals to control and prevent malnutrition in the country, recommended that a national nutrition surveillance system should be developed. For the purpose of deciding policies and to formulate programmes to control and prevent malnutrition, it is essential to assess What? Where? How? and Why? of the nutrition problems in the country. Monitoring of the nutritional status of population, therefore, becomes an important aspect of any nutrition programmes to assess the impact of these massive inputs and to determine the direction in which the community’s nutrition is progressing, so as to initiate appropriate corrective actions. The Indian Council of Medical Research (ICMR), hence, established National Nutrition Monitoring Bureau (NNMB) in the year 1972, with a Central Reference Laboratory at the National Institute of Nutrition, Hyderabad. To start with, the bureau was established in the States of Andhra Pradesh, Gujarat, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Orissa, Tamil Nadu, Uttar Pradesh and West Bengal. OBJECTIVES OF NNMB To collect, on a continuous basis, on representative segments of population in each of the states data on dietary pattern and nutritional status adopting standardized and uniform procedures and techniques, and To periodically evaluate the ongoing national nutrition programmes, to identify their strengths and weaknesses and to recommend appropriate corrective measures. ORGANIZATION Separate teams of research investigators, who are either Medical graduates or postgraduates in Nutrition/ Sociology, collect information on diet and nutritional status of population. All the members of the team are given intensive training in the methods of data collection, analysis and interpretation. Each state has also been provided with a vehicle for field survey. ORGANIZATION STEERING COMMITTEE ICMR NIN-CRL Medical Officer Nutritionist Social Worker 10 State Units Field Attendant Driver COLLABORATION WITH STATES The NNMB was envisaged, at the outset, as a collaborative exercise between the Indian Council of Medical Research and the respective State governments. The team has, therefore, been put under the administrative control of the State Nutrition Officer. The team gets necessary cooperation from the local staff and is provided with adequate facilities so that it could complete the survey as per schedule. However, in the States of Andhra Pradesh, Madhya pradesh, Orissa and Uttar Pradesh, the NNMB units are attached to the ICMR Institutes/Regional Centers. DATA Well-trained investigators, in each state, collect information on dietary pattern and nutritional status of population in rural, tribal or urban areas on a representative sample, by adopting prescribed standard procedures and using accurate equipment. The details of data collected are indicated below Household demographic and socioeconomic status, Dietary intake of individuals and households, Nutritional anthropometry on all the available members of the households, Village level information on population, agricultural production, nutrition and other developmental programmes. UNIQUE FEATURES OF NNMB NNMB is not a routine data collecting organization. It has several special features The unique features are : Organization of repeat surveys in 1988-90 and 1996-97, in the same villages in all the States that were surveyed during 1975-79, to assess time trends in diet and nutritional situation. NNMB generates data periodically on diet and nutritional status of socially vulnerable groups of population like the tribals living in the integrated tribal development project areas, and the population at-risk physiologically like elderly population and adolescents. NNMB is the only organization involved in continuous collection of data on actual intakes of families, and individuals belonging to different physiological and age groups, in different states Assessment of intra-family distribution of foods and nutrients Perhaps, one of the advantages of the bureau is availability of expertise of the NIN to carry out detailed analysis of the data to provide policy directions. SAMPLING The NNMB, in the beginning, adopted the sampling design, developed in consultation with Prof. C.R.Rao, a world-renowned statistician. Since 1990, to obtain better spatial distribution and representativeness, a subsample of NSSO sample is covered. AP GUJ KAR. KER. MP . MAH. ORI. T.N. U.P. W.B States 16 Strata 5 Villages Households Nutrition Assessment : 20 Dietary Assessment : 10 TOTAL COVERAGE/STATE Nutrition Assessment : 1600 Dietary Assessment : 800 For the purpose, the sampling frame of the National Sample Survey Organization (NSSO) f or its Consumer Expenditure Surveys is used. In each state, 80 villages are covered from 16 strata (districts) in three subrounds. The strata are so selected that all are represented in each subround so as to take care of any seasonal variations. COVERAGE The cumulative coverage by the NNMB, so far, is indicated below: CUMULATIVE COVERAGE Type of Area Rural Tribal Urban Slums Other Urban Groups Total Household Diet Survey 29,514 Not done 1,633 Individual Diet Survey 27,289 46,347 2,087 Nutrition Assessment 3,79,062 1,32,416 13,699 2,379 3,628 24,080 33,526 79,351 5,49,302 SALIENT SCIENTIFIC OBSERVATIONS Food and Nutrient intakes About 30% of households consume less than 70% of energy requirements. The diets of children under the age of 5 years of age are more inadequate than those of adults and are well below the recommended dietary allowances. Woefully inadequate consumption of protective foods like pulses, green leafy vegetables, and milk & milk products. Dietary micronutrient deficiency, particularly with respect to vitamin A and iron, is wide spread. About 80% of the individuals consume diets, which provide less than half of the RDA for these micronutrients. Intra-family distribution of foods and nutrients reveals that preschool children get less than their physiological needs as compared to adult males and females. INTRA-FAMILY DISTRIBUTION OF DIETARY ENERGY : PERCENT HOUSEHOLDS ACCORDING TO ADEQUACY STATUS OF ADULTS Vs PRESCHOOL CHILD ADULT + CHILD ADEQUACY 31% ADULT INADEQUACY CHILD ADEQUACY 10% ADULT ADEQUACY CHILD INADEQUACY 25% ADULT + CHILD INADEQUACY 34% Nutritional Status of Population About a half of the children are underweight and about 40% are stunted. The prevalence of underweight and stunting is considerably high even among adolescents About a half of the adults and elderly suffer from chronic energy deficiency as measured by body mass index (< 18.5) There is no gender bias with respect to nutritional status of females. DISTRIBUTION (%) OF PRESCHOOL CHILDREN ACCORDING TO WEIGHT FOR AGE BY SEX SEVERE 5.8% NORMAL 8.8% MODERAT E 44.8% MILD 40.6% BOYS SEVERE 5.8% MODERAT E 44.8% GIRLS NORMAL 8.8% MILD 40.6% About a quarter of the adolescent girls are married before the age of 18 years and among them about 25% are at risk of maternal problems due to their short stature (<145cm). Nutritional status of tribals is worse than their rural counterparts. TIME TRENDS Repeat surveys, in the same villages surveyed about 20-25 years back, indicate improvement in the intakes of energy & protein in all the age groups of individuals. Percent DISTRIBUTION (%) OF 1-6 YEAR CHILDREN WITH NUTRIENT INTAKES BELOW 70% OF RDI 100 90 80 70 60 50 40 30 20 10 0 86.3 87.8 1975-79 71.6 71.4 1996-97 61.2 54.6 46.7 49.3 27.3 11.1 Energy Protein Vit.A Nutrients Iron Ribo.

The extent of undernutrition and stunting declined during the past two decades. There was reduction in the prevalence of nutritional deficiency signs over time. Secular trends in linear growth of adolescents were observed. GIRLS There was reduction in the extent of chronic energy deficiency in adults as compared to those studied in 1975-79. USERS OF NNMB DATA The State governments, the Planning Commission, Department of Women and Child Development (nodal agency for nutrition), UNICEF, WHO, FAO, Home Science college involved in Food and Nutrition, international agencies like CARE and voluntary organizations such as Nutrition Foundation of India make use of the data generated by the NNMB. The bureau published regularly the reports of all its annual surveys, a compilation of 25 years of work of NNMB, reports on the nutritional status of Indian adolescents, elderly population and a report on the dietary intakes of individuals of different age and physiological groups. Two Ph.D. theses have also been published.
