Cost Effective Analysis (CEA)

• Usually, once a particular welfare policy is selected after CBA, Cost effective analysis is used to identify the least expensive method of attaining that definite result.
– CEA involves choosing one among different possible ways for achieving the desired result.
– E.g. it was calculated that ‘reduction in indoor air pollution’ would result in greatest economic benefit (after CBA) to the population, various possible ways of achieving this are analyzed using cost – effective analysis

Cost Benefit Analysis (CBA)

• Public funds are never sufficient. Hence, there is a need to rank various projects so that the officials can select the intervention that would deliver the highest monetary return to the population
• The next ranked intervention would be considered when more funds become available or after the first one is complete
• Hence, in CBA, costs and benefits are expressed in monetary terms i.e.'cost= money spent' and 'benefit = money saved +money earned'.

Methods of Dietary Survey

Dietary survey is done to assess the quantities of food items and nutrients consumed by the family or an individual. The nutrition composition is calculated using tables of nutritive value of common foods. These tables are given in the ICMR publication: Nutritive Value of Indian Foods.
There are various methods of dietary survey. Each is suitable for a different set of circumstances.

Concept of the “Consumption Unit”

When the food intake of a community or a group of people is to be measured, the practical problem that arises is that the group is constituted by individuals of various ages and sex groups. Each group has a different set of such groups.
To resolve this issue, it is usual to assess the needs of women and children in terms of those of the average man by applying appropriate coefficients of calorie consumption suggested for practical nutrition work in India.
