Recent Clinical VAD
Survey: Nepal Micronutrient Status Survey |
|
Date: |
Dec 1997- May 1998 |
|
Groups Surveyed: |
Women, children 6-59
months, and children 6-11 years of age |
|
Sample Size: |
Children 6-59
mos: 17,550 |
|
|
Children 6-11
yrs: 15,600 |
|
|
Women: 15,600 |
|
Sampling Method: |
Two- stage cluster
survey |
|
Sampling Strategy: |
The survey was conducted
nationally, but was designed to provide sub-national and regional estimates
by selecting representative samples from each of the thirteen Eco-
development zones (based on 3 Eco- zones and 5 development regions). The
two- stage cluster design was used to select 30 clusters from each of the
Eco-development zones, and 40 households from each of the selected
clusters. Household eligibility was determined to be the presence of a
woman with a pre-school aged child. The sample sizes were then weighted
based on analysis of differences among Eco- development zones. |

*The
estimates for the population affected were based on the US Census Bureau
population estimates for Nepal 2000. The number of women affected is based
on the estimated population of women ages 15-49. Children 6-59 months were
based on the population of children 0-5 years. The population of children
6-11 years was based on estimates of the number of children 5-10 years |
