II. METHODOLOGY

A. Questionaire

In order to be consistent with the baseline and midterm survey results the same survey instruments were used for this final survey.  They included an adaptation of the John Hopkins PVO-CSSP standardized KPC survey, height and weight measures of all children in the sample, dietary intake assessment (HKI), direct dietary weights of foods consumed, and tests for vitamin A, iron, and iodine in salt.   See Table 1.

Survey Instruments

KPC:  This is relatively the same questionnaire that was used in the previous surveys, except new sections on ARI and malaria were included. (See appendix for sample survey).  It was developed by the CSSP, and reviewed by the field team.  Any questions that were not relevant to this study were discarded and others that were of relevant value were added.  Wording and the names of foods were also adapted to the local situations.  The MINSA staff have reviewed it and given their approval.  In addition, it was tested in the field on June 26, 2000 in Asentamiento Humano Las Palmeras, Morales District.  

Food Consumption:  A HKI (Helen Keller International) revised  food frequency form  was used to identify breastfeeding practices and the foods most commonly given to the children (under 2yrs.) in each household.  This was especially helpful in ascertaining the level of vitamin A and iron rich foods that are being consumed.

Direct Weight of Foods:  In order to understand what and how much food the children and families were consuming, the method of direct weighing was used.  This method supplies us with quantitative information about the nutrients (esp. proteins, vitamin A, and Iron) that the children and families are ingesting.  This procedure began with the  weighing of all raw ingredients for that meal.  After preparation the meal was again weighed according to the proportions given to each person.  In addition, any left over food was weighed.  All foods were weighed with an electronic balance (within 2 grams of precision).  This process was done for all meals consumed in that day.  There was a total of 84 households that were surveyed, all from the 4 year intervention communities.  The analysis of these surveys was done by PRISMA.
