Household wealth and child health in India.

Using data from the Indian National Family Health Surveys (1992-93, 1998-99, 2005-06), this study examined how the relationship between household wealth and child health evolved during a time of significant economic change in India. The main predictor was an innovative measure of household wealth that captures changes in wealth over time. Discrete-time logistic models (with community fixed effects) were used to examine mortality and malnutrition outcomes: infant, child, and under-5 mortality; stunting, wasting, and being underweight. Analysis was conducted at the national, urban/rural, and regional levels, separately for boys and girls. The results indicate that the relationship between household wealth and under-5 mortality weakened over time but this result was dominated by infant mortality. The relationship between wealth and child mortality stayed strong for girls. The relationship between household wealth and malnutrition became stronger over time for boys and particularly for girls, in urban and (especially) rural areas.

Household Microbial Water Quality Testing in a Peruvian Demographic and Health Survey: Evaluation of the Compartment Bag Test for Escherichia coli.

AbstractThe Joint Monitoring Program relies on household surveys to classify access to improved water sources instead of measuring microbiological quality. The aim of this research was to pilot a novel test for Escherichia coli quantification of household drinking water in the 2011 Demographic and Health Survey (DHS) in Peru. In the Compartment Bag Test (CBT), a 100-mL water sample is supplemented with chromogenic medium to support the growth of E. coli, poured into a bag with compartments, and incubated. A color change indicates E. coli growth, and the concentration of E. coli/100 mL is estimated as a most probable number. Triplicate water samples from 704 households were collected; one sample was analyzed in the field using the CBT, another replicate sample using the CBT was analyzed by reference laboratories, and one sample using membrane filtration (MF) was analyzed by reference laboratories. There were no statistically significant differences in E. coli concentrations between the field and laboratory CBT results, or when compared with MF results. These results suggest that the CBT for E. coli is an effective method to quantify fecal bacteria in household drinking water. The CBT can be incorporated into DHS and other national household surveys as a direct measure of drinking water safety based on microbial quality to better document access to safe drinking water.

Dimensions of the emerging orphan crisis in sub-Saharan Africa.

This study uses recent Demographic and Health Survey (DHS) data to examine levels, trends, and differentials in orphan prevalence in sub-Saharan Africa. The first part of the analysis presents direct estimates of orphan prevalence in 17 countries during the period 1995-2000. We find a strong correlation between orphanhood prevalence and national adult HIV prevalence estimates lending support to the interpretation of the orphan crisis as, in large part, AIDS-related. The second part of the analysis consists of an in-depth study of trends and age-patterns in orphan prevalence and welfare in the 1990s for five countries that have had widely divergent HIV prevalence levels (Zimbabwe, Kenya, Tanzania, Ghana, and Niger). The vulnerability of orphans with respect to their situation in households and educational opportunities is evaluated in relation to non-orphans' experience. The results of the analysis indicate that losing one or both parents is significantly associated with diminished chances of being at the appropriate grade level for age. Our results are interpreted in the context of societal responses to the crisis, and potential recommendations for intervention.

Success in reducing maternal and child mortality in Afghanistan.

After the collapse of the Taliban regime in 2002, Afghanistan adopted a new development path and billions of dollars were invested in rebuilding the country's economy and health systems with the help of donors. These investments have led to substantial improvements in maternal and child health in recent years and ultimately to a decrease in maternal and child mortality. The 2010 Afghanistan Mortality Survey (AMS) provides important new information on the levels and trends in these indicators. The AMS estimated that there are 327 maternal deaths for every 100,000 live births (95% confidence interval = 260-394) and 97 deaths before the age of five years for every 1000 children born. Decreases in these mortality rates are consistent with changes in key determinants of mortality, including an increasing age at marriage, higher contraceptive use, lower fertility, better immunisation coverage, improvements in the percentage of women delivering in health facilities and receiving antenatal and postnatal care, involvement of community health workers and increasing access to the Basic Package of Health Services. Despite the impressive gains in these areas, many challenges remain. Further improvements in health services in Afghanistan will require sustained efforts on the part of both the Government of Afghanistan and international donors.

Fertility preferences and the need for contraception among women living with HIV: the basis for a joint action agenda.

OBJECTIVES: HIV-positive women have particular needs for contraception to avoid unwanted pregnancy, to protect their own health and to eliminate the risk of transmitting HIV to an infant. In 2004, the United Nations described a four-element strategy to preventing mother-to-child transmission of HIV; the second element is preventing unintended pregnancies among HIV-positive women. However, fertility preferences among HIV-positive women who know their status remain poorly understood. This study seeks to demonstrate the degree to which knowledge of one's own serostatus is associated with fertility preferences and contraceptive demand and use. METHODS: This study uses Demographic and Health Surveys data and bivariate and multivariate methods to assess the contribution of a proxy variable for knowledge of own HIV serostatus to women's fertility desires, demand for contraception and contraceptive method choice for Zambia, Swaziland, Zimbabwe and Lesotho. RESULTS: Knowledge of one's own HIV-positive serostatus is significantly associated with a desire to limit childbearing with contraceptive use, but not necessarily with unmet need for contraception. HIV-positive women who know their status are more likely than other women to use condoms. CONCLUSION: HIV-positive women who know their serostatus exhibit fertility desires and contraceptive behaviors that are different from those of other women. These findings support the argument that efforts to scale up the second element of the strategy to prevent mother-to-child transmission of HIV should be accelerated: it is a cost-effective, rights-based approach to preventing incidence of mother-to-child transmission of HIV. Scaling up requires full commitment by both reproductive health/family planning and HIV constituencies to concerted integration at all levels of program planning, coordination and implementation.

HIV infection does not disproportionately affect the poorer in sub-Saharan Africa.

BACKGROUND: Wealthier populations do better than poorer ones on most measures of health status, including nutrition, morbidity and mortality, and healthcare utilization. OBJECTIVES: This study examines the association between household wealth status and HIV serostatus to identify what characteristics and behaviours are associated with HIV infection, and the role of confounding factors such as place of residence and other risk factors. METHODS: Data are from eight national surveys in sub-Saharan Africa (Kenya, Ghana, Burkina Faso, Cameroon, Tanzania, Lesotho, Malawi, and Uganda) conducted during 2003-2005. Dried blood spot samples were collected and tested for HIV, following internationally accepted ethical standards and laboratory procedures. The association between household wealth (measured by an index based on household ownership of durable assets and other amenities) and HIV serostatus is examined using both descriptive and multivariate statistical methods. RESULTS: In all eight countries, adults in the wealthiest quintiles have a higher prevalence of HIV than those in the poorer quintiles. Prevalence increases monotonically with wealth in most cases. Similarly for cohabiting couples, the likelihood that one or both partners is HIV infected increases with wealth. The positive association between wealth and HIV prevalence is only partly explained by an association of wealth with other underlying factors, such as place of residence and education, and by differences in sexual behaviour, such as multiple sex partners, condom use, and male circumcision. CONCLUSION: In sub-Saharan Africa, HIV prevalence does not exhibit the same pattern of association with poverty as most other diseases. HIV programmes should also focus on the wealthier segments of the population.

Defining nutritional status of women in developing countries.

OBJECTIVE: To define a de facto reference body mass index (BMI) for women in developing countries and compare its performance with the Quetelet BMI. DESIGN: A logarithmic equation for elite wt/ht references was developed using the weight (wt) and height (ht) of 10,524 non-pregnant elite mothers. Functional outcomes were compared using both BMIs. SETTING: Forty-six national surveys from 36 developing countries. SUBJECTS: Mothers 15-49 years old. RESULTS: The defacto reference standard deviation showed 2.2% of elite women were undernourished and 6.3% overnourished; lower and upper limits for 'ideal' wt/ht were 73% and 137%, respectively. Compared with the age-based and medium frame standards of the First and Second National Health and Nutrition Examination Surveys (NHANES I & II), the defacto reference defined fewer women as undernourished (5.3% vs. 10.5% and 14.4%, respectively), but more as overnourished (20.4% vs. 13.7% and 15.9%, respectively). In the de facto reference, BMI = wt/ht(1.6). Using the age-based and medium-frame-based Quetelet BMI (wt/ht2), 28.5% and 31.7% had a low and 13.0% and 14.7% a high BMI, respectively. For the defacto reference, 18.4% of the elite mothers had a low BMI and 19.3% a high BMI. Applying the de facto reference to all women showed that the distribution of BMI was similar irrespective of the reference used. Functional outcomes were similar for both BMIs. CONCLUSIONS: The NHANES I & II growth curves define more women as overnourished than the de facto curve, but the opposite for defining the undernourished. Functional outcomes were similar for both BMIs, suggesting there is no great advantage to using a defacto BMI based on national-level data from these 46 national surveys.

Estimation of births averted due to breast-feeding and increases in levels of contraception needed to substitute for breast-feeding.

After contraceptive use, breast-feeding duration is the major determinant of the birth interval length. Three methods of estimating births averted by breast-feeding, and the increase in contraceptive use needed to substitute for breast-feeding, are presented. Method 1 simply utilizes Bongaarts' Ci, and the other two are based on mean birth intervals with and without breast-feeding. Estimates for each method are derived for six countries with DHS surveys from the mid-1990s: Burkina Faso, Uganda, India, Indonesia, Brazil and Peru. The estimated percentage of additional births that would occur if there were no breast-feeding ranged from 1-4%, in Brazil to about 50% in Burkina Faso and Uganda, reflecting very low breast-feeding in Brazil and very high levels in the sub-Saharan African nations. Strengths and limitations of the three methods are considered.

[Prenatal care at the first level of care: characteristics of providers that affect users' satisfaction]. / Atención prenatal en el primer nivel de atención: características de los proveedores que influyen en la satisfacción de las usuarias.

OBJECTIVE: To assess the satisfaction level attained by prenatal care users in primary health services in Mexico, and to compare the level of satisfaction according to characteristics of the provider and the service. MATERIAL AND METHODS: A cross-sectional survey was conducted to analyze data from 217 care provider-user pairs. Interviews were carried out in 95 primary care units in eight Mexican states. The information was collected through a) direct observation of the medical encounter, b) interviews with providers and users, and c) a questionnaire and knowledge examination to providers. Users' satisfaction was analyzed according to providers' clinical ability and the treatment received during the visit. Summary and dispersion measures of the main issues were calculated, as well as bivariate and trends analysis. RESULTS: User satisfaction in prenatal care is associated with the treatment received during the visit and to the waiting time before being attended, but not with the provider's clinical ability, nor with his or her age or gender. The treatment received during the visit was also associated with the user's socioeconomic level, where the poorer users received the worst treatment. CONCLUSIONS: Health services should assess users' satisfaction according with the type of medical encounter, particularly where resources are scarce and where economic disparities are present. In such cases, the provision of healthcare services may intensify inequality, with greater impact on the poorest.

Atención prenatal en el primer nivel de atención: características de los proveedores que influyen en la satisfacción de las usuarias / Prenatal care in the primary level of healthcare: provider characteristics which influence users' satisfaction

OBJETIVO: Evaluar el nivel de satisfacción alcanzado por las usuarias de los servicios de atención prenatal en el primer nivel de atención en México, y comparar con algunas características del proveedor y del servicio. MATERIAL Y MÉTODOS: Mediante la aplicación de una encuesta transversal, en el año 2000, se investigaron 217 pares de proveedores-usuarias de servicios de salud, entrevistados en 95 unidades de atención de primer nivel de ocho entidades federativas de la República Mexicana. Se recopiló información mediante: a) observación directa de la consulta médica, b) entrevistas a proveedores y usuarias, y c) aplicación de cuestionario y examen de conocimiento a los proveedores. Se analizó la relación existente entre la capacidad de resolución clínica de los proveedores, el trato recibido durante la consulta y la satisfacción sobre la misma que la usuaria manifestó en entrevista directa. Para ello se calcularon las medidas de resumen y dispersión de las principales categorías, así como análisis bivariado y de tendencias. RESULTADOS: La satisfacción de las usuarias de los servicios de atención prenatal está relacionada con el trato recibido durante la consulta y el tiempo que esperó para recibirla, pero no con la capacidad de resolución clínica del profesional, ni con su edad o género. El trato recibido durante la consulta por la paciente también se asoció con su nivel socioeconómico y se encontró que las usuarias más pobres reciben, proporcionalmente, peor trato. CONCLUSIONES: Los servicios de salud podrían realizar evaluaciones de la satisfacción de sus pacientes en relación con la consulta recibida, en especial en aquellos lugares en los que existe escasez de recursos y/o condiciones de desigualdad económica. En estos casos la prestación de los servicios puede profundizar las diferencias entre la población, y afectar más a la población más pobre.
