    Monitoring Change in Child Mortality through Household Surveys
    (Public Library of Science, 2015) Hill, Kenneth; Brady, Eoghan; Zimmerman, Linnea; Montana, Livia; Silva, Romesh; Amouzou, Agbessi
    Background: Most low- and middle-income countries lack fully functional civil registration systems. Measures of under-five mortality are typically derived from periodic household surveys collecting detailed information from women on births and child deaths. However, such surveys are expensive and are not appropriate for monitoring short-term changes in child mortality. We explored and tested the validity of two new analysis methods for less-expensive summary histories of births and child deaths for such monitoring in five African countries. Methods and Findings: The first method we explored uses individual-level survey data on births and child deaths to impute full birth histories from an earlier survey onto summary histories from a more recent survey. The second method uses cohort changes between two surveys in the average number of children born and the number of children dead by single year of age to estimate under-five mortality for the inter-survey period. The first method produces acceptable annual estimates of under-five mortality for two out of six applications to available data sets; the second method produced an acceptable estimate in only one of five applications, though none of the applications used ideal data sets. Conclusions: The methods we tested were not able to produce consistently good quality estimates of annual under-five mortality from summary birth history data. The key problem we identified was not with the methods themselves, but with the underlying quality of the summary birth histories. If summary birth histories are to be included in general household surveys, considerable emphasis must be placed on quality control.

    Integration of family planning with maternal health services: an opportunity to increase postpartum modern contraceptive use in urban Uttar Pradesh, India
    (BMJ Publishing Group, 2016) Achyut, Pranita; Mishra, Anurag; Montana, Livia; Sengupta, Ranajit; Calhoun, Lisa M; Nanda, Priya
    Background: Maternal health (MH) services provide an invaluable opportunity to inform and educate women about family planning (FP). It is expected that this would enable women to choose an appropriate method and initiate contraception early in the postpartum period. In this study we examined interactions with health providers for MH services, and the effect of FP information provision during these interactions on the postpartum use of modern contraceptive methods. Methods: This study used midline data collected from 990 women who had delivered a live birth between January 2010 and the date of the midline survey in 2012. These women were asked a series of questions about their last delivery, including interactions with health providers during pregnancy, delivery and the postpartum period, if they received FP information during these interactions, and their contraceptive use during the postpartum period. Results: The study found that FP information provision as part of antenatal care in the third trimester, delivery and the postpartum period have a positive association with postpartum modern contraceptive use in urban Uttar Pradesh. However, health providers often miss these opportunities. Despite a high proportion of women coming into contact with health providers when utilising MH services, only a small proportion received FP information during these interactions. Conclusions: Integration of FP with MH services can increase postpartum modern contraceptive use. With the launch of the National Urban Health Mission, there now exists appropriate policy and programmatic environments for integration of FP and MH services in urban settings in India. However, this will require a concentrated effort both to enhance the capacity of health providers and encourage supportive supervision.

    Comparison of HIV Prevalence Estimates from Antenatal Care Surveillance and Population-Based Surveys in Sub-Saharan Africa
    (BMJ Publishing Group, 2008) Montana, Livia; Mishra, V; Hong, R
    Objective: To compare HIV seroprevalence estimates obtained from antenatal care (ANC) sentinel surveillance surveys in Ethiopia, Kenya, Malawi, Tanzania and Uganda with those from population-based demographic and health surveys (DHS) and AIDS indicator surveys (AIS). Methods: Geographical information system methods were used to map ANC surveillance sites and DHS/AIS survey clusters within a 15-km radius of the ANC sites. National DHS/AIS HIV prevalence estimates for women and men were compared with national prevalence estimates from ANC surveillance. DHS/AIS HIV prevalence estimates for women and men residing within 15 km of ANC sites were compared with those from ANC surveillance. For women, these comparisons were also stratified by current pregnancy status, experience of recent childbirth and receiving ANC for the last birth. Results: In four of the five countries, national DHS/AIS estimates of HIV prevalence were lower than the ANC surveillance estimates. Comparing women and men in the catchment areas of the ANC sites, the DHS/AIS estimates were similar to ANC surveillance estimates. DHS/AIS estimates for men residing in the catchment areas of ANC sites were much lower than ANC surveillance estimates for women in all cases. ANC estimates were higher for younger women than DHS/AIS estimates for women in ANC catchment areas, but lower at older ages. In all cases, urban prevalence was higher than rural prevalence but there were no consistent patterns by education. Conclusions: ANC surveillance surveys tend to overestimate HIV prevalence compared to prevalence among women in the general population in DHS/AIS surveys. However, the ANC and DHS/AIS estimates are similar when restricted to women and men, or to women only, residing in catchment areas of ANC sites. Patterns by age and urban/rural residence suggest possible bias in the ANC estimates.
