2. INTRODUCTION
• Nutritional status of an individual is influenced
by:
- Adequacy of food intake (quality & quantity)
- Physical health of the individual
• Nutritional status of a community is the sum
of the nutritional status of the individuals who
form that community.
3. Objective of Comprehensive Nutritional Survey
• To obtain precise information on the
prevalence and geographic distribution of
nutritional problems of a given community
• Identification of individuals or population
groups “at risk” or in greatest need of
assistance
4. RECOMMENDED DIETARY ALLOWANCE (RDA)
• The average daily dietary nutrient intake level
sufficient to meet the nutrient requirement of
nearly all (97-98%) healthy individuals in a
particular life stage and gender group.
5. ASSESSMENT OF NUTRITIONAL STATUS
• Purpose : To develop healthcare programme to meet the needs
Evaluation of the effectiveness of such programmes
• Process: Examination of random and representative sample of
population
All ages, both sexes in different socio-economic
groups
Drawing valid conclusions
Survey – Duration , Type (Cross/ Longitudinal)
Measurement techniques & Instruments
6. ASSESSMENT METHODS
1) Clinical examination – Signs ( WHO expert committee )
a) Not related to nutrition – Alopecia, Pyorrhea, pterygium
b) That need further investigations - Molar pigmentation,
Corneal vascularisation, geographic tongue
c) Non to be value – Angular steatites, Bigots spots, calf
tenderness, Absence knee / ankle jerks ( Beri-beri ),
Enlargement of thyroid gland ( Endemic goiter )
2) Anthropometry – Recorded over a period of time
3) Biochemical Assessment – Hb , Urine – Albumin / Sugar
4) Functional indicators – Prothrombin time , Sperm count, Heart rate.
7. Assessment Methods – ( Cont )
5) Assessment of dietary intake:
i) Weighment of raw foods
ii) Weighment of cooked foods
iii) Oral questionnaire Method
6) Vital and Health statistics: Mortality & Morbidity
7) Assessment of Ecological factors:
a) Food balance sheet
b) Socio economic factors – family size , occupation, income,
education, customs,
c) Health and education services
d) Conditioning influences
i. Parasitic infestation
ii. Bacterial & viral infections
8. Oral Questionnaire Method
• Useful in carrying out a diet survey of a large
number of people in a short time.
• Inquiries about the nature and quantity of
foods eaten during the previous 24 or 8 hours
retrospectively.
9. Dietary Assessment
• Data collected from a diet survey has to be
translated into
• Mean intake (grams) of food in terms of
cereals, pulses, vegetables, fruits, milk, meat,
fish, eggs.
• The mean intake of nutrients of nutrients per
adult man value or “consumption unit”
10. Dietary Survey
• Diet survey provides information about dietary
intake patterns, specific foods consumed and
estimated nutrient intakes.
• It indicates relative dietary inadequacies as
judged by present standards.
• Provides valuable information for planning
health education activities as well as extent and
nature of changes needed in the agriculture and
food production industries.

17. Dietary Coefficients of Individuals
Group Coefficients (Units)
Adult male (Sedentary worker) 1.0
Adult male (Moderate worker) 1.2
Adult male (Heavy worker) 1.6
Adult female (Sedentary worker) 0.8
Adult female (Moderate worker) 0.9
Adult female (Heavy worker) 1.2
Adolescents 10 to 19 years 1.0
Children 9 to 12 years 0.8
Children 7 to 9 years 0.7
Children 5 to 7 years 0.6
Children 3 to 5 years 0.5
18. Dietary Assessment
Any individuals dietary assessment is calculated
based on Energy Consumption Units(ECU),
which is 2400.
ECU X Dietary Coefficient (DU) (according to the Type
of work & Gender) gives the Dietary requirement of an
individual
For e.g. A Doctor’s dietary requirement is 2400 x 1 = 2400
19. Dietary Assessment
Consider a family consisting of 4 members
Their Dietary intake on 02/06/2021 is
Breakfast : Poha & 4 cups of tea
Lunch: 7 Chapatti's, Rice, Dhal & Sabji
