Demographic survey of the level and determinants of perinatal mortality in Karachi, Pakistan.

A demographic survey was used to estimate the level and determinants of perinatal mortality in eight lower socio-economic squatter settlements of Karachi, Pakistan. The perinatal mortality rate was 54.1 per 1000 births, with a stillbirth to early neonatal mortality ratio of 1:1. About 65% of neonatal deaths occurred in the early neonatal period, and early neonatal mortality contributed 32% of all infant deaths. Risk factor assessment was conducted on 375 perinatal deaths and 6070 current survivors. Poorer socio-economic status variables such as maternal and paternal illiteracy, maternal work outside the home and fewer household assets were significantly associated with perinatal mortality as were biological factors of higher parental age, short birth intervals and poor obstetric history. Multivariable logistic analysis indicated that some socio-economic factors retained their significance after adjusting for the more proximate biological factors. Population attributable risk estimates suggest that public health measures for screening of high-risk women and use of family planning to space births will not improve perinatal mortality substantially without improvement of socio-economic conditions, particularly maternal education. The results of this study indicate that an evaluation of perinatal mortality can be conducted using pregnancy histories derived from demographic surveys.

Fertility and family planning in Vietnam: evidence from the 1994 Inter-censal Demographic Survey.

Results from the 1994 Vietnam Inter-censal Demographic Survey reveal substantial change over recent years in reproductive behavior and attitudes. Fertility has continued to decline to a level not far above a total fertility rate of three children per woman. Compared with the late 1980s, contraceptive knowledge has broadened and contraceptive prevalence has increased, reaching a level of 65 percent of currently married women of reproductive age. The dominance of the IUD among modern methods has been reduced somewhat. Stated family-size preferences have shifted noticeably downward. Recently married women indicate that they want only 2.3 children, on average, suggesting that fertility will continue to fall in coming years. These findings suggest that Vietnam is in the midst of a transition that will lead to low levels of fertility in the near future.

Current fertility: a first glimpse from the 1983 National Demographic Survey.

This paper highlights initial findings from the 1983 National Demographic Surveys (NDS) based on a 25% sub-sample of the survey respondents. The discussion focuses on measures of current fertility as well as on selected fertility "predictors" for the 3 major island groups -- Luzon, Visay, and Mindanao. Owing to the restrictive nature of the data set, no statistical tests are performed to measure the influence on fertility of these explanatory variables. Instead, inferences are drawn from a descriptive analysis of the patterns exhibited. Findings point to a continuation of fertility decline as evidenced by the estimated crude birthrate of 33.6 births/1000.

Serological and demographic survey of Epstein-Barr virus infection in Ethiopia.

A demographic and serological survey of Epstein-Barr virus infection was carried out in 5 geographically representative regions of Ethiopia. 80% of the 500 people studied were under 15 years of age. 82% of children under 5 years of age and 94% under 10 years of age were positive for IgG anti-viral capsid antigen (VCA) antibody. 51 of 100 children under 12 months of age and from 5 different provinces were positive for anti-VCA antibody. Of these, 23 were under 6 months. The distribution of anti-VCA antibody positivity was comparable in both sexes, in each age group and in the different provinces at different altitudes. Economic status, expressed in terms of estimated income, type of water supply, mode of excreta disposal and family size, did not significantly influence the distribution of anti-VCA antibody. Thus, early exposure to Epstein-Barr virus, with asymptomatic or subclinical presentation, probably accounts for the rarity of typical infectious mononucleosis in young adult Ethiopians. The lack of a relationship between Epstein-Barr virus infection and Burkitt's lymphoma, nasopharyngeal carcinoma, malaria as well as liver diseases is briefly discussed.

Age at first sex: understanding recent trends in African demographic surveys.

OBJECTIVES: To describe recent trends in age at first sex in African countries, identifying and making due allowances for a variety of common reporting errors. METHODS: Demographic and Health Surveys (DHS) data from six African countries conducting three or more surveys since 1985 were analysed using survival analysis techniques, combining information on virginity status and retrospective reporting of age at first sex. Hazard analysis was used to separate the effects of reporting error and compositional change and to estimate true changes in sexual debut over time. A multistate life table analysis incorporating transition to first marriage allowed cohorts to be classified according to person years spent as virgins, as sexually active unmarried, and married. RESULTS: Intersurvey comparisons generally suggested a slow secular rise in age at first sex. However, tracing birth cohorts between surveys revealed inconsistencies--median ages reported by female members of a birth cohort in their teens were generally higher than those reported when they reached their twenties, even when allowing for residence and education changes--probably a result of young, sexually active women denying they had ever had sex. Male birth cohorts tend to display the opposite kind of bias. CONCLUSIONS: Uganda, Kenya, and Ghana have experienced a more pronounced and unambiguous decline in premarital sexual activity than Tanzania, Zambia, and Zimbabwe, with statistically significant increases in age at first sex. In addition, Uganda has maintained a very short interval between onset of sexual activity and marriage for both sexes.

Geovisualization to support the exploration of large health and demographic survey data.

BACKGROUND: Survey data are increasingly abundant from many international projects and national statistics. They are generally comprehensive and cover local, regional as well as national levels census in many domains including health, demography, human development, and economy. These surveys result in several hundred indicators. Geographical analysis of such large amount of data is often a difficult task and searching for patterns is particularly a difficult challenge. Geovisualization research is increasingly dealing with the exploration of patterns and relationships in such large datasets for understanding underlying geographical processes. One of the attempts has been to use Artificial Neural Networks as a technology especially useful in situations where the numbers are vast and the relationships are often unclear or even hidden. RESULTS: We investigate ways to integrate computational analysis based on a Self-Organizing Map neural network, with visual representations of derived structures and patterns in a framework for exploratory visualization to support visual data mining and knowledge discovery. The framework suggests ways to explore the general structure of the dataset in its multidimensional space in order to provide clues for further exploration of correlations and relationships. CONCLUSION: In this paper, the proposed framework is used to explore a demographic and health survey data. Several graphical representations (information spaces) are used to depict the general structure and clustering of the data and get insight about the relationships among the different variables. Detail exploration of correlations and relationships among the attributes is provided. Results of the analysis are also presented in maps and other graphics.

Age estimation from the number of teeth erupted in young children: an aid to demographic surveys.

The reporting of children's ages by parents is surprisingly inaccurate in many innumerate societies, but accurate knowledge of age is important for estimating recent changes in demographic rates. The timing of the eruption of children's teeth is largely independent of environmental influences and can provide a relatively accurate and unbiased estimate of a child's age. We have collected published data from 42 studies of children's dentition and have transformed them into estimates of age for children with particular numbers of teeth. We present estimates for different populations, but the lack of significant differences between these estimates justifies the use of a standard set.
