Examining the “Urban Advantage” in Maternal Health Care in Developing Countries

Andrew Channon and colleagues outline the complexities of urban advantage in maternal health where the urban poor often have worse access to health care than women in rural areas.

Maternal mortality in adolescents compared with women of other ages: evidence from 144 countries

BACKGROUND Adolescents are often noted to have an increased risk of death during pregnancy or childbirth compared with older women, but the existing evidence is inconsistent and in many cases contradictory. We aimed to quantify the risk of maternal death in adolescents by estimating maternal mortality ratios for women aged 15-19 years by country, region, and worldwide, and to compare these ratios with those for women in other 5-year age groups. METHODS We used data from 144 countries and territories (65 with vital registration data and 79 with nationally representative survey data) to calculate the proportion of maternal deaths among deaths of females of reproductive age (PMDF) for each 5-year age group from 15-19 to 45-49 years. We adjusted these estimates to take into account under-reporting of maternal deaths, and deaths during pregnancy from non-maternal causes. We then applied the adjusted PMDFs to the most reliable age-specific estimates of deaths and livebirths to derive age-specific maternal mortality ratios. FINDINGS The aggregated data show a J-shaped curve for the age distribution of maternal mortality, with a slightly increased risk of mortality in adolescents compared with women aged 20-24 years (maternal mortality ratio 260 [uncertainty 100-410] vs 190 [120-260] maternal deaths per 100 000 livebirths for all 144 countries combined), and the highest risk in women older than 30 years. Analysis for individual countries showed substantial heterogeneity; some showed a clear J-shaped curve, whereas in others adolescents had a slightly lower maternal mortality ratio than women in their early 20s. No obvious groupings were apparent in terms of economic development, demographic characteristics, or geographical region for countries with these different age patterns. INTERPRETATION Our findings suggest that the excess mortality risk to adolescent mothers might be less than previously believed, and in most countries the adolescent maternal mortality ratio is low compared with women older than 30 years. However, these findings should not divert focus away from efforts to reduce adolescent pregnancy, which are central to the promotion of womens educational, social, and economic development.

Childbearing in adolescents aged 12-15 years in low resource countries: a neglected issue. New estimates from demographic and household surveys in 42 countries.

There is strong evidence that the health risks associated with adolescent pregnancy are concentrated among the youngest girls (e.g. those under 16 years). Fertility rates in this age group have not previously been comprehensively estimated and published. By drawing data from 42 large, nationally representative household surveys in low resource countries carried out since 2003 this article presents estimates of age‐specific birth rates for girls aged 12–15, and the percentage of girls who give birth at age 15 or younger. From these we estimate that approximately 2.5 million births occur to girls aged under 16 in low resource countries each year. The highest rates are found in Sub‐Saharan Africa, where in Chad, Guinea, Mali, Mozambique, Niger and Sierra Leone more than 10% of girls become mothers before they are 16. Strategies to reduce these high levels are vital if we are to alleviate poor reproductive health.

The geography of maternal and newborn health: the state of the art

As the deadline for the millennium development goals approaches, it has become clear that the goals linked to maternal and newborn health are the least likely to be achieved by 2015. It is therefore critical to ensure that all possible data, tools and methods are fully exploited to help address this gap. Among the methods that are under-used, mapping has always represented a powerful way to ‘tell the story’ of a health problem in an easily understood way. In addition to this, the advanced analytical methods and models now being embedded into Geographic Information Systems allow a more in-depth analysis of the causes behind adverse maternal and newborn health (MNH) outcomes. This paper examines the current state of the art in mapping the geography of MNH as a starting point to unleashing the potential of these under-used approaches. Using a rapid literature review and the description of the work currently in progress, this paper allows the identification of methods in use and describes a framework for methodological approaches to inform improved decision-making. The paper is aimed at health metrics and geography of health specialists, the MNH community, as well as policy-makers in developing countries and international donor agencies.

Adolescent first births in East Africa: disaggregating characteristics, trends and determinants

BackgroundThe use of a single national figure fails to capture the complex patterns and inequalities in early childbearing that occur within countries, as well as the differing contexts in which these pregnancies occur. Further disaggregated data that examine patterns and trends for different groups are needed to enable programmes to be focused on those most at risk. This paper describes a comprehensive analysis of adolescent first births using disaggregated data from Demographic and Household surveys (DHS) for three East African countries: Uganda, Kenya and Tanzania.MethodsThe study initially produces cross-sectional descriptive data on adolescent motherhood by age (under 16, 16–17 and 18–19 years), marital status, wealth, education, state or region, urban/rural residence and religion. Trends for two or more surveys over a period of 18–23 years are then analysed, and again disaggregated by age, wealth, urban/rural residence and marital status to ascertain which groups within the population have benefited most from reductions in adolescent first birth. In order to adjust for confounding factors we also use multinomial logistic regression to analyse the social and economic determinants of adolescent first birth, with outcomes again divided by age.FindingsIn all three countries, a significant proportion of women gave birth before age 16 (7%-12%). Both the bivariate analysis and logistic regression show that adolescent motherhood is strongly associated with poverty and lack of education/literacy, and this relationship is strongest among births within the youngest age group (<16 years). There are also marked differences by region, religion and urban/rural residence. Trends over time show there has been limited progress in reducing adolescent first births overall, with no reductions among the poorest.ConclusionsAdolescent first births, particularly at the youngest ages, are most common among the poorest and least educated, and progress in reducing rates within this group has not been made over the last few decades. Disaggregating data allows such patterns to be understood, and enables efforts to be better directed where needed.

Financial accessibility and user fee reforms for maternal healthcare in five sub-Saharan countries: a quasi-experimental analysis.

Objectives Evidence on whether removing fees benefits the poorest is patchy and weak. The aim of this paper is to measure the impact of user fee reforms on the probability of giving birth in an institution or undergoing a caesarean section (CS) in Ghana, Burkina Faso, Zambia, Cameroon and Nigeria for the poorest strata of the population. Setting Womens experience of user fees in 5 African countries. Primary and secondary outcome measures Using quasi-experimental regression analysis we tested the impact of user fee reforms on facilities’ births and CS differentiated by wealth, education and residence in Burkina Faso and Ghana. Mapping of the literature followed by key informant interviews are used to verify details of reform implementation and to confirm and support our countries’ choice. Participants We analysed data from consecutive surveys in 5 countries: 2 case countries that experienced reforms (Ghana and Burkina Faso) by contrast with 3 that did not experience reforms (Zambia, Cameroon, Nigeria). Results User fee reforms are associated with a significant percentage of the increase in access to facility births (27 percentage points) and to a much lesser extent to CS (0.7 percentage points). Poor (but not the poorest), and non-educated women, and those in rural areas benefitted the most from the reforms. User fees reforms have had a higher impact in Burkina Faso compared with Ghana. Conclusions Findings show a clear positive impact on access when user fees are removed, but limited evidence for improved availability of CS for those most in need. More women from rural areas and from lower socioeconomic backgrounds give birth in health facilities after fee reform. Speed and quality of implementation might be the key reason behind the differences between the 2 case countries. This calls for more research into the impact of reforms on quality of care.

How Reliable Are Reports of Early Adolescent Reproductive and Sexual Health Events In Demographic and Health Surveys

CONTEXT Age at sexual debut, age at first marriage or first union and age at first birth are among the most widely used indicators of health and well-being for female adolescents. However, the accuracy of estimates for these indicators, particularly for younger adolescents, is poorly understood. METHODS For each of nine countries in Africa and Latin America, Demographic and Health Survey (DHS) data from two surveys conducted five years apart were used to examine womens reports of age at sexual debut, marriage or first union, and first birth. The consistency of estimates between surveys and across birth cohorts is described, focusing particularly on the reporting of events occurring before age 15 and age 16. RESULTS Marked differences in estimates for very early first births and marriage were found. Women aged 15-19 were much less likely to report marriages and first births before age 15 than were women from the same birth cohort when asked five years later at ages 20-24. Early sexual debut was reported more consistently in consecutive surveys than early marriages or births. CONCLUSIONS Caution should be exercised when inferring changes in early adolescent sexual and reproductive health on the basis of estimates from the DHS. Greater effort should be made to develop data collection instruments that reduce misreporting of self-reported data from women sampled in household surveys.

The impact of young maternal age at birth on neonatal mortality: Evidence from 45 low and middle income countries

Objectives This study explores the impact of early motherhood on neonatal mortality, and how this differs between countries and regions. It assesses whether the risk of neonatal mortality is greater for younger adolescent mothers compared with mothers in later adolescence, and explores if differences reflect confounding socio-economic and health care utilisation factors. It also examines how the risks differ for first or subsequent pregnancies. Methods The analysis uses 64 Demographic and Health Surveys collected between 2005 and 2015 from 45 countries to explore the relationship between adolescent motherhood (disaggregated as <16 years, 16/17 years and 18/19 years) and neonatal mortality. Both unadjusted bivariate association and logistic regression are used. Regional level multivariate models that adjust for a range of socio-economic, demographic and health service utilisation variables are estimated. Further stratified models are created to examine the excess risk for first and subsequent births separately. Findings The risk of neonatal mortality in all regions was markedly greater for infants with mothers under 16 years old, although there was marked heterogeneity in patterns between regions. Adjusting for socio-economic, demographic and health service utilisation variables did not markedly change the odds ratios associated with age. The increased risks associated with adolescent motherhood are lowest for first births. Conclusion Our findings particularly highlight the importance of reducing adolescent births among the youngest age group as a strategy for addressing the problem of neonatal mortality, as well ensuring pregnant adolescents have access to quality maternal health services to protect the health of both themselves and their infants. The regional differences in increased risk are a novel finding which requires more exploration.

Understanding processes of risk and protection that shape the sexual and reproductive health of young women affected by conflict: the price of protection

BackgroundIt is assumed that knowing what puts young women at risk of poor sexual health outcomes and, in turn, what protects them against these outcomes, will enable greater targeted protection as well as help in designing more effective programmes. Accordingly, efforts have been directed towards mapping risk and protective factors onto general ecological frameworks, but these currently do not take into account the context of modern armed conflict. A literature overview approach was used to identify SRH related risk and protective factors specifically for young women affected by modern armed conflict.Processes of risk and protectionA range of keywords were used to identify academic articles which explored the sexual and reproductive health needs of young women affected by modern armed conflict. Selected articles were read to identify risk and protective factors in relation to sexual and reproductive health. While no articles explicitly identified ‘risk’ or ‘protective’ factors, we were able to extrapolate these through a thorough engagement with the text. However, we found that it was difficult to identify factors as either ‘risky’ or ‘protective’, with many having the capacity to be both risky and protective (i.e. refugee camps or family). Therefore, using an ecological model, six environments that impact upon young women’s lives in contexts of modern armed conflict are used to illustrate the dynamic and complex operation of risk and protection – highlighting processes of protection and the ‘trade-offs’ between risks.ConclusionWe conclude that there are no simple formulaic risk/protection patterns to be applied in every conflict and post-conflict context. Instead, there needs to be greater recognition of the ‘processes’ of protection, including the role of ‘trade-offs’ (what we term as ‘protection at a price’), in order to further effective policy and practical responses to improve sexual and reproductive health outcomes during or following armed conflict. Focus on specific ‘factors’ (such as ‘female headed household’) takes attention away from the processes through which factors manifest themselves and which often determine whether the factor will later be considered ‘risk inducing’ or protective.

Excess risk of maternal mortality in adolescent mothers – Authors' reply

Authors’ reply We strongly agree with Ann Blanc, who clearly highlights the dangers of so-called accepted wisdom based on limited or flawed evidence, and the need to question and probe the provenance of data used to direct resources and plan policies. This is indeed an important lesson for the maternal health community as we move forward with setting priorities for national and global maternal health agendas. We would also like to emphasise that we do not see our findings as negating the need to focus on reducing adolescent births in some contexts. Increased risk of mortality is only one of the potential negative outcomes that can result from early motherhood, and a holistic approach that assesses evidence of potential adverse effects on education, opportunities, and general wellbeing, as well as health (for mother and baby) should be used to guide policy in this area. We were also unable in our study to estimate whether younger adolescents (eg, aged 12–15 years) experienced higher mortality than their older adolescent counterparts, and this is an area we will be researching in future to further develop our understanding of risks to young mothers. We declare that we have no competing interests.
