National health surveys based on representative samples have found a place in the health information systems in less developed countries. This paper will present the special issues raised by health examination population-based surveys as this relate to statistical methodologies. Issues to be discussed include the trade off between statistical efficiency and logistical efficiency in sampling design, design effects, and analytical methods. Limitations due to irregularity of census activities in some less developed nations and its implication for the quality of data will be discussed.
Learning Objectives: At the conclusion of the session, the participant in this session will be able to: 1. Evaluate the trade-offs between optimally efficient methods of survey design and analysis and practicality in the conduct of health examination surveys in less developed countries (LDCs). 2. Describe how limitations of census data can be expected to affect the quality of information from health examination surveys in LDCs.
