Sampling
The sample was designed to provide demographic and health indicators, including fertility and childhood mortality rates, at the national level and for urban and rural areas. The sample design specified a target of 800 female respondents in each of the five sampling regions. In addition, on request of the Ministry of Health and UNICEF, the Autonomous Republic of Karakalpakstan and Ferghana Oblast were over sampled to provide approximately 800 women in each, yielding a target sample size of approximately 5,600 women. Fertility rates and other indicators were estimated for the regions.
A weighted, multistage, stratified, cluster sampling design was employed. In total, 219 sample clusters were selected for the sample (101 in urban areas and 118 in rural areas). Then, a household list- ing operation was conducted in each sample cluster. The final selection of approximately 20 households per cluster was made at survey headquarters in Tashkent using systematic random sampling. The selected sample consisted of 4,385 households.
All selected households that were occupied were eligible for the Household Questionnaire. In all regions, all women age 15-49 in the selected households were eligible for the Women's Questionnaire. Eligibility for the Men's Questionnaire differed between Tashkent City and the other four regions. In Tashkent City, all men age 15-59 in the selected households were eligible respondents, while in the four remaining regions only men age 15-59 in every third household were eligible respondents. The rationale for a larger sample of men from Tashkent City was to ensure a sufficient number of observations to per- mit gender comparisons of the biodata collected only in Tashkent City.
Note: Appendix A of the final report provides more information on the sample design.
A total of 4,385 households were selected, of which 4,207 were occupied households. Household interviews were completed for 4,168 households, for a household response rate of 99.1 percent of the occupied households. A total of 5,588 eligible women were found in the occupied households, and interviews were completed for 5,463 women, for an eligible woman response rate of 97.8 percent. The overall response rate for women (the product of the household and eligible woman response rates) was 96.9 percent.
For the men’s sample, a total of 2,094 households were selected, of which 2,007 were occupied households. Household interviews were completed for 1,982 households, for a household response rate of 98.8 percent of the occupied households. A total of 2,447 eligible men were found in the occupied households, and interviews were completed for 2,333 men, for an eligible man response rate of 95.3 percent. The overall response rate for men (the product of the household and eligible man response rates) was 94.2
percent.
The overall response rates were high for both women and men, although somewhat higher for women (96.9) than for men (94.2 percent). For both women and men, the overall rates did not differ greatly between urban and rural areas or among the regions, with the single exception that the rates were somewhat lower for the East-Central region (93.0 percent for women and 88.1 percent for men).
Survey instrument
The UHES employed three survey instruments: a Household Questionnaire, a Women’s Questionnaire, and a Men’s Questionnaire. The survey instruments were based on the model questionnaires developed by the MEASURE DHS+ project augmented by modules on topics related to adult health. The data collection instruments were reviewed and approved by an Advisory Committee of subject matter experts appointed by the Minister of Health during the summer of 2001.
Data collection
| Start | End |
|---|---|
| 2002-09 | 2002-12 |
Sixty-five medical personnel, mostly physicians, were recruited and trained to be staff for the interviewing teams. Training, which started on August 12 and continued for four weeks, was conducted in Uzbek and Russian and consisted of lectures, demonstrations, and practice interviewing. Two physicians from the MOH who had participated in the pretest conducted the training. Staff from the Demographic and Health Surveys program assisted with the training. The fourth week of training consisted of field practice conducted on a team basis.
On September 9, data collection started in Tashkent City and within a few days in the four remaining regions. By December 15, all interviewing teams had completed data collection in their regions.
Data processing
Data processing took place at the Analytical and Information Center of the Ministry of Health. The office editing staff checked to confirm that questionnaires for all selected households and all eligible respondents were returned from the field. The few questions that had not been precoded (e.g., occupation) were coded at this time. The data were then entered and edited on computers using the ISSA(Integrated System for Survey Analysis) package, with the data entry software translated into Russian. Office editing and data entry activities were conducted between September 2002 and February 2003.
Data appraisal
The estimates from a sample survey are affected by two types of errors: 1) nonsampling errors, and 2) sampling errors. Nonsampling errors are the results of mistakes made in implementing data collection and data processing, such as failure to locate and interview the correct household, misunderstanding of the questions by either the interviewer or the respondent, and data entry errors. Although numerous efforts were made during the implementation of the 2002 Uzbekistan Health Examination Survey (UHES) to minimize this type of error, nonsampling errors are impossible to avoid and difficult to evaluate statistically.
Sampling errors, on the other hand, can be evaluated statistically. The sample of respondents selected in the 2002 UHES is only one of many samples that could have been selected from the same population, using the same design and expected size. Each of these samples would yield results that differ somewhat from the results of the actual sample selected. Sampling errors are a measure of the variability between all possible samples. Although the degree of variability is not known exactly, it can be estimated from the survey results.
A sampling error is usually measured in terms of the standard error for a particular statistic (e.g., mean, percentage), which is the square root of the variance. The standard error can be used to calculate confidence intervals within which the true value for the population can reasonably be assumed to fall. For example, for any given statistic calculated from a sample survey, the value of that statistic will fall within a range of plus or minus two times the standard error of that statistic in 95 percent of all possible samples of identical size and design.
If the sample of respondents had been selected as a simple random sample, it would have been possible to use straightforward formulas for calculating sampling errors. However, the 2002 UHES sample is the result of a multistage stratified design and, consequently, it was necessary to use more complex formulas. The computer software used to calculate sampling errors for the 2002 UHES is the Integrated System for Survey Analysis (ISSA) Sampling Error Module. This module used the Taylor linearization method of variance estimation for survey estimates that are means or proportions. The Jackknife repeated replication method is used for variance estimation of more complex statistics such as fertility and mortality rates.
A more detailed description of estimates of sampling errors are presented in Appendix B of the survey report.
