NUTRITIONAL STATUS OF THE COMMUNITIES IN THE RURAL AREAS - Current Scenario
Dr.G.N.V.Brahmam Dy. Director (Sr. Gr.), HoD,
Division of Community Studies,
National Institute of Nutrition, (I.C.M.R.)
Jamai-Osmania (P.O.),
Hyderabad – 500 007.
“Nutrition monitoring is the measurement of the changes over time in the nutritional status of a population or a specific group of
individuals” -- WHO, 1984Nutrition Monitoring is essential
- to assess the type, magnitude & distribution of
nutrition problems in the community,
- to evolve policies and to formulate & implement
programmes for the prevention and control of
malnutrition and
- to evaluate on-going nutrition programmes to
assess their impact and to initiate corrective
steps needed, if any.
NUTRITIONAL SURVEILLANCE
“ TO WATCH OVER NUTRTION IN ORDER TO MAKE
DECISIONS WHICH WILL LEAD TO IMPROVEMENT
IN NUTRITION IN POPULATIONS”. NUTRITIONAL
SURVEILLANCE METHODS PROVIDE REGULAR
INFORMATION ABOUT NUTRITION IN POPULATION;
THEY DRAW DATA FROM MOST SUITABLE
SOURCES THAT ARE ALREADY AVAILBLE,
INCLUDING SURVEYS AND ADMINISTATIVE DATA.
THE UNDERTAKING OF ADHOC INVESTIGATIONS
CAN ALSO BE INCLUDED IN NUTRITIONAL
SURVEILLANCE. FAO/WHO/UNICEF EXPERT COMMITTEE (1976) AND ELABORATED UPON BY MASON et al, 1984
HOUSEHOLD FOOD SECURITY:
Ability of the Household to access food which is culturally acceptable and adequate in terms of quality, quantity and safety for all members of the household throughout the year, in order to ensure active and healthy life
HOUSEHOLD FOOD INSECURITY:
Presently or potential inability to consume food which is adequate, having all the nutrients essential for a healthy and productive life.
NNMB was established in the year 1972, under the aegis of ICMR in the States of :
ANDHRA PRADESH
KARNATAKA
KERALA
TAMIL NADU
MAHARASHTRA
MADHYA PRADESH
ORISSA
UTTAR PRADESH
GUJARAT 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 by adopting standardized and uniform
procedures and techniques, and
To evaluate periodically, the ongoing national
nutrition programmes, to identify their strengths
and weaknesses and recommend appropriate
corrective measures.

INVESTIGATIONS
Household demographic & socio-economic
particulars,
Dietary intakes of households / individuals,
Anthropometry viz., Heights, weights, MUAC &
Skinfold at Triceps,
Clinical examination for prevalence of signs of
nutritional deficiencies and
Village level information such as population,
agricultural production, nutritional & other
developmental programmes.
SAMPLING DESIGN
VILLAGES:
Sub-sample of NSSO sample frame of Consumer Expenditure survey carried out once in five years – to get better spatial distribution.
HOUSEHOLDS
Cluster sampling method
INDIVIDUALS
All individuals from the selected HHs.
Sub-sample by systematic random sampling procedure
SAMPLE SIZE
• Computed to arrive at State level estimates
HIGHLIGHTS OF NNMB SURVEYS
Coverage of rural, tribal & urban communities,
Repeat surveys in rural communities during 1975-
79, 88-90, and 96-97, covering same villages,
Repeat surveys among tribal communities during
1985-87 & 1998-99,
Study of physiologically vulnerable groups such
as adolescent girls, elderly etc.,
Assessment of MNDs such as IDA, VAD & IDD by
covering adequate sample sizes to arrive at State
level estimates, and
Evaluation National nutrition programmes
