What explains the fall in child stunting in Sub-Saharan Africa?

There have been steep falls in rates of child stunting in much of Sub-Saharan Africa (SSA). Using Demographic and Health Survey data, we document significant reductions in stunting in seven SSA countries in the period 2005-2014. For each country, we distinguish potential determinants that move in a direction consistent with having contributed to the reduction in stunting from those that do not. We then decompose the change in stunting and in proximal determinants into a part that can be explained by changes in distal determinants and a residual part that captures the impact of unmeasured factors, such as vertical nutrition programs. We show that increases in coverage of child immunization, deworming medication and maternal iron supplementation often coincide with a fall in stunting. The magnitudes and directions of changes in two other proximal determinants -- age-appropriate feeding and diarrhea prevalence -- suggest that these have not been strong contributors to the fall in stunting. Utilization of maternity care emerges from the decomposition analysis as the most important distal determinant associated with reduced stunting, and also with increased coverage of iron supplementation, and, to a lesser extent, with child immunization and deworming medication. This circumstantial evidence is strong enough to warrant more detailed investigation of the extent to which maternity care is an effective channel through which to target further attacks on the blight of undernourished children.

Impact and spill-over effects of an asset transfer program on child undernutrition: Evidence from a randomized control trial in Bangladesh.

Targeting the Ultra-poor (TUP) is an integrated programme that combines the transfer of income-generating assets and multifaceted training on entrepreneurship, health-nutrition, and social awareness over a two-year period to graduate ultra-poor with mainstream poverty. While positive socioeconomic effects and spill-over effects are well-documented, this is the first paper to evaluate the effects of the programme on nutritional outcomes of under-5 children using data from a randomized control trial over a four-year period. We find notable improvements in nutritional outcomes of children in participating households. TUP is further seen to improve food-security, sanitation and duration of exclusive-breastfeeding. Nutrition status of children living in poor non-participant households are also positively affected though no effects were found on children from non-poor households. We conclude that programmes that combine asset transfer with multifaceted training such as TUP can have significant long-term positive health effects.

Socioeconomic inequalities in newborn care during facility and home deliveries: a cross sectional analysis of data from demographic surveillance sites in rural Bangladesh, India and Nepal.

BACKGROUND: In Bangladesh, India and Nepal, neonatal outcomes of poor infants are considerably worse than those of better-off infants. Understanding how these inequalities vary by country and place of delivery (home or facility) will allow targeting of interventions to those who need them most. We describe socio-economic inequalities in newborn care in rural areas of Bangladesh, Nepal and India for all deliveries and by place of delivery. METHODS: We used data from surveillance sites in Bangladesh, India and from Makwanpur and Dhanusha districts in Nepal, covering periods from 2001 to 2011. We used literacy (ability to read a short text) as indicator of socioeconomic status. We developed a composite score of nine newborn care practices (score range 0-9 indicating infants received no newborn care to all nine newborn care practices). We modeled the effect of literacy and place of delivery on the newborn care score and on individual practices. RESULTS: In all study sites (60,078 deliveries in total), use of facility delivery was higher among literate mothers. In all sites, inequalities in newborn care were observed: the difference in new born care between literate and illiterate ranged 0.35-0.80. The effect of literacy on the newborn care score reduced after adjusting for place of delivery (range score difference literate-illiterate: 0.21-0.43). CONCLUSION: Socioeconomic inequalities in facility care greatly contribute to inequalities in newborn care. Improving newborn care during home deliveries and improving access to facility care are a priority for addressing inequalities in newborn care and newborn mortality.

Voluntary health insurance in Nigeria: Effects on takers and non-takers.

Interventions aiming to simultaneously improve financial protection and quality of care may provide an important avenue towards universal health coverage. We estimate the effects of the introduction of the Kwara State Health Insurance program in Nigeria on not only the insured but also the uninsured. A subsidized voluntary low cost health insurance was offered by a private insurer as well as a quality upgrade in selected health care facilities. Using propensity score matching and panel data collected in 2009 and 2011 (n = 3509), we find that, for the insured, the program increased health care utilization (36 percent, p < 0.000) and reduced out of pocket expenditure (63 percent, p < 0.000). However, the uninsured in the area with upgraded facilities did not increase their care utilization and even spent less on health care, which is problematic given that 67 percent of the population in the treatment area did not take up the insurance. Our findings suggest that while voluntary health insurance combined with investments in health care supply can increase health care use and financial protection among those that take up the insurance, attention should be paid to potential unintended effects on the - typically sizeable- group of people who do not enroll in the insurance.

Did contracting effect the use of primary health care units in Pakistan?

For many years, Pakistan has had a wide network of Basic Health Units spread across the country, but their utilization by the population in rural and peri-urban areas has remained low. As of 2004, in an attempt to improve the utilization and performance of these public primary healthcare facilities, the government has gradually started contracting-in intergovernmental organizations to manage these BHUs. Using five nationally representative household surveys conducted between 2001 and 2012, and exploiting the gradual roll-out of this reform to apply a difference-in-difference approach, we evaluate its impact on BHU utilization. We find that contracting of the BHU management did not have any effect on health care use generally in the population, but it did significantly increase the use of BHU for childhood diarrhoea for the poor (by 4% points) and rural (3% points) households. These increases were accompanied by lower rates of self-treatment and private facilities usage. We do not find any significant effects on the self-reported satisfaction with BHU utilization. Our findings contrast with earlier small-scale studies that reported larger effects of the contracting of primary care in Pakistan. We speculate that the modest additional budget, the limited management authority of the contracting agency and the lack of clear performance indicators are reasons for the small impact of the contracting reform. Apparently critical aspects of services delivery such as location of BHUs, ineffective referral system and medical practice variation in public and private sectors have contributed to the overall low utilization of BHUs, yet these were beyond the scope of the contracting reform.

How equitable is the uptake of conditional cash transfers for maternity care in India? Evidence from the Janani Suraksha Yojana scheme in Odisha and Jharkhand.

BACKGROUND: In 2005, the Indian Government introduced the Janani Suraksha Yojana (JSY) scheme - a conditional cash transfer program that incentivizes women to deliver in a health facility - in order to reduce maternal and neonatal mortality. Our study aimed to measure and explain socioeconomic inequality in the receipt of JSY benefits. METHODS: We used prospectively collected data on 3,682 births (in 2009-2010) from a demographic surveillance system in five districts in Jharkhand and Odisha state, India. Linear probability models were used to identify the determinants of receipt of JSY benefits. Poor-rich inequality in the receipt of JSY benefits was measured by a corrected concentration index (CI), and the most important drivers of this inequality were identified using decomposition techniques. RESULTS: While the majority of women had heard of the scheme (94% in Odisha, 85% in Jharkhand), receipt of JSY benefits was comparatively low (62% in Odisha, 20% in Jharkhand). Receipt of the benefits was highly variable by district, especially in Jharkhand, where 5% of women in Godda district received the benefits, compared with 40% of women in Ranchi district. There were substantial pro-rich inequalities in JSY receipt (CI 0.10, standard deviation (SD) 0.03 in Odisha; CI 0.18, SD 0.02 in Jharkhand) and in the institutional delivery rate (CI 0.16, SD 0.03 in Odisha; CI 0.30, SD 0.02 in Jharkhand). Delivery in a public facility was an important determinant of receipt of JSY benefits and explained a substantial part of the observed poor-rich inequalities in receipt of the benefits. Yet, even among public facility births in Jharkhand, pro-rich inequality in JSY receipt was substantial (CI 0.14, SD 0.05). This was largely explained by district-level differences in wealth and JSY receipt. Conversely, in Odisha, poorer women delivering in a government institution were at least as likely to receive JSY benefits as richer women (CI -0.05, SD 0.03). CONCLUSION: JSY benefits were not equally distributed, favouring wealthier groups. These inequalities in turn reflected pro-rich inequalities in the institutional delivery. The JSY scheme is currently not sufficient to close the poor-rich gap in institutional delivery rate. Important barriers to institutional delivery remain to be addressed and more support is needed for low performing districts and states.

The Effects of Ghana's National Health Insurance Scheme on Maternal and Infant Health Care Utilization.

Increasing equitable access to health care is a main challenge African policy makers are facing. The Ghanaian government implemented the National Health Insurance Scheme in 2004 and the aim of this study is to evaluate its early effects on maternal and infant healthcare use. We exploit data on births before and after the intervention and apply propensity score matching to limit the bias arising from self-selection into the health insurance. About forty percent of children had a mother who is enrolled in this insurance. The scheme significantly increased the proportion of pregnancies with at least four antenatal care visits with 7 percentage points and had a significant effect on attended deliveries (10 percentage points). Caesarean sections increased (6 percentage points) and the number of children born from an unwanted pregnancy decreased (7 percentage points). Insurance enrollment had almost no effect on child vaccinations. Among the poorest forty percent of the sample, the effects of the scheme on antenatal care and attended deliveries were similar. However, the effects of the scheme on caesarean sections were about half the size (3 percentage points) and the reduction in unwanted pregnancies was larger (10 percentage points) compared to the effects in the full sample. We conclude that in the first years of operation, the National Health Insurance Scheme had a modest impact on the use of antenatal and delivery care. This is important for other African countries currently introducing or considering a national health insurance as a means towards universal health coverage.

Healthcare seeking behaviour among self-help group households in Rural Bihar and Uttar Pradesh, India.

BACKGROUND: In recent years, supported by non-governmental organizations (NGOs), a number of community-based health insurance (CBHI) schemes have been operating in rural India. Such schemes design their benefit packages according to local priorities. This paper examines healthcare seeking behaviour among self-help group households with a view to understanding the implications for the benefit packages offered by such schemes. METHODS: We use cross-sectional data collected from two of India's poorest states and estimate an alternative-specific conditional logit model to examine healthcare seeking behaviour. RESULTS: We find that the majority of respondents do access some form of care and that there is overwhelming use of private providers. Non-degree allopathic providers (NDAP) also called rural medical practitioners are the most popular providers. In the case of acute illnesses, proximity plays an important role in determining provider choice. For chronic illnesses, cost of care influences provider choice. CONCLUSION: Given the importance of proximity in determining provider choice, benefit packages offered by CBHI schemes should consider coverage of transportation costs and reimbursement of foregone earnings.

Impact of Performance-Based Financing in a Low-Resource Setting: A Decade of Experience in Cambodia.

This paper exploits the geographic expansion of performance-based financing (PBF) in Cambodia over a decade to estimate its effect on the utilization of maternal and child health services. PBF is estimated to raise the proportion of births occurring in incentivized public health facilities by 7.5 percentage points (25%). A substantial part of this effect arises from switching the location of institutional births from private to public facilities; there is no significant impact on deliveries supervised by a skilled birth attendant, nor is there any significant effect on neonatal mortality, antenatal care and vaccination rates. The impact on births in public facilities is much greater if PBF is accompanied by maternity vouchers that cover user fees, but there is no significant effect among the poorest women. Heterogeneous effects across schemes differing in design suggest that maintaining management authority within a health district while giving explicit service targets to facilities is more effective in raising utilization than contracting management to a non-governmental organization while denying it full autonomy and leaving financial penalties vague.

Impact of Community-based Health Insurance on Access and Financial Protection: Evidence from Three Randomized Control Trials in Rural India.

Since the 1990s, community-based health insurance (CBHI) schemes have been proposed to reduce the financial consequences of illness and enhance access to healthcare in developing countries. Convincing evidence on the ability of such schemes to meet their objectives is scarce. This paper uses randomized control trials conducted in rural Uttar Pradesh and Bihar (India) to evaluate the effects of three CBHI schemes on healthcare utilization and expenditure. We find that the schemes have no effect on these outcomes. The results suggest that CBHI schemes of the type examined in this paper are unlikely to have a substantial impact on access and financial protection in developing countries.

Economic consequences of ill-health for households in northern rural India.

BACKGROUND: As compared to other countries in South East Asia, India's health care system is characterized by very high out of pocket payments, and consequently low financial protection and access to care. This paper describes the relative importance of ill-health compared to other adverse events, the conduits through which ill-health affects household welfare and the coping strategies used to finance these expenses. METHODS: Cross-sectional data are used from a survey conducted with 5241 households in Uttar Pradesh and Bihar in 2010 that included a household shocks module and detailed information about health care use and spending. RESULTS: Health-related adverse events were the second most common adverse events (34%), after natural disasters (51%). Crop and livestock disease and weddings each affected about 8% of households. Only a fourth of households reported to have recovered from illness and/or death in the family (by the time of the survey). Most of the households' economic burden related to ill-health was depending on direct medical costs, but indirect costs (such as lost earnings and transportation or food costs) were also not negligible. Close to half of the health expenditures were made for chronic conditions. Households tried to cope with health-related expenditures mostly by dissaving, borrowing and selling assets. Few households reported having to reduce (food) consumption in response to ill-health. CONCLUSIONS: In the absence of pre-financing schemes, ill-health events pose a substantial threat to household welfare in rural India. While most households seem to be able to smooth consumption in the short term, coping strategies like selling assets and borrowing from moneylenders are likely to have severe long term consequences. As most of the households' economic risk related to ill-health appears to depend on out of pocket spending, introducing health insurance may contribute significantly to alleviate economic hardship for families in rural India. The importance of care for chronic diseases, however, represents a big challenge for the sustainability of community based health insurance schemes, since it is necessary to ensure a sufficient degree of risk pooling.

Gastric cancer survival and affiliation to health insurance in a middle-income setting.

OBJECTIVE: To investigate whether health insurance affiliation and socioeconomic deprivation is associated with overall cause survival from gastric cancer in a middle-income country. METHODS: All patients resident in the Bucaramanga metropolitan area (Colombia) diagnosed with gastric cancer between 2003 and 2009 (n=1039), identified in the population-based cancer registry, were followed for vital status until 31/12/2013. Kaplan-Meier models provided crude survival estimates by health insurance regime (HIR) and social stratum (SS). Multivariate Cox-proportional hazard models adjusting HIR and SS for sex, age and tumor grade, were performed. RESULTS: Overall 1 and 5 year survival proportions were 32.4% and 11.0%, respectively, varying from 49.3% and 15.8% for patients affiliated to the most generous HIR to 12.9% and 5.3% for unaffiliated patients, and from 41.4% and 20.7% for patients in the highest SS, versus 27.1% and 7.4% for the lowest SS. The multivariate analyses showed type of HIR as well as SS to remain independently associated with survival, with an 11% improvement in survival for each increase in SS subgroup (HR 0.89 (95% CI 0.83; 0.96), and with worse survival in the subsidized (least generous) HIR and unaffiliated patients compared to the contributory HIR (HR subsidized 1.20 (95% CI 1.00; 1.43) and HR not affiliated 2.03 (95% CI 1.48; 2.78)). Of the non-affiliated patients, 60% had died at the time of diagnosis, versus 4-14% of affiliated patients (p<0.0005). CONCLUSIONS: Despite the 'universal' health insurance system, large socioeconomic differences in gastric cancer survival exist in Colombia. Both social stratum and access to effective diagnostic and curative care strongly influence survival.

Introduction of performance-based financing in burundi was associated with improvements in care and quality.

Several governments in low- and middle-income countries have adopted performance-based financing to increase health care use and improve the quality of health services. We evaluated the effects of performance-based financing in the central African nation of Burundi by exploiting the staggered rollout of this financing across provinces during 2006-10. We found that performance-based financing increased the share of women delivering their babies in an institution by 22 percentage points, which reflects a relative increase of 36 percent, and the share of women using modern family planning services by 5 percentage points, a relative change of 55 percent. The overall quality score for health care facilities increased by 45 percent during the study period, but performance-based financing was found to have no effect on the quality of care as reported by patients. We did not find strong evidence of differential effects of performance-based financing across socioeconomic groups. The performance-based financing effects on the probability of using care when ill were found to be even smaller for the poor. Our findings suggest that a supply-side intervention such as performance-based financing without accompanying access incentives for poor people is unlikely to improve equity. More research into the cost-effectiveness of performance-based financing and how best to target vulnerable populations is warranted.

The effects of performance incentives on the utilization and quality of maternal and child care in Burundi.

Africa's progress towards the health related Millennium Development Goals remains limited. This can be partly explained by inadequate performance of health care providers. It is therefore critical to incentivize this performance. Payment methods that reward performance related to quantity and quality, called performance based financing (PBF), have recently been introduced in over 30 African countries. While PBF meets considerable enthusiasm from governments and donors, the evidence on its effects is still limited. In this study we aim to estimate the effects of PBF on the utilization and quality of maternal and child care in Burundi. We use the 2010 Burundi Demographic and Health Survey (August 2010-January 2011, n = 4916 women) and exploit the staggered rollout of PBF between 2006 and 2010, to implement a difference-in-differences approach. The quality of care provided during antenatal care (ANC) visits improved significantly, especially among the better off, although timeliness and number of ANC visits did not change. The probability of an institutional delivery increased significantly with 4 percentage points among the better off but no effects were found among the poor. PBF does significantly increase this probability (with 5 percentage points) for women where PBF was in place from the start of their pregnancy, suggesting that women are encouraged during ANC visits to deliver in the facility. PBF also led to a significant increase of 4 percentage points in the probability of a child being fully vaccinated, with effects more pronounced among the poor. PBF improved the utilization and quality of most maternal and child care, mainly among the better off, but did not improve targeting of unmet needs for ANC. Especially types of care which require a behavioral change of health care workers when the patient is already in the clinic show improvements. Improvements are smaller for services which require effort from the provider to change patients' utilization choices.

Can vouchers deliver? An evaluation of subsidies for maternal health care in Cambodia.

OBJECTIVE: To evaluate the effect of vouchers for maternity care in public health-care facilities on the utilization of maternal health-care services in Cambodia. METHODS: The study involved data from the 2010 Cambodian Demographic and Health Survey, which covered births between 2005 and 2010. The effect of voucher schemes, first implemented in 2007, on the utilization of maternal health-care services was quantified using a difference-in-differences method that compared changes in utilization in districts with voucher schemes with changes in districts without them. FINDINGS: Overall, voucher schemes were associated with an increase of 10.1 percentage points (pp) in the probability of delivery in a public health-care facility; among women from the poorest 40% of households, the increase was 15.6 pp. Vouchers were responsible for about one fifth of the increase observed in institutional deliveries in districts with schemes. Universal voucher schemes had a larger effect on the probability of delivery in a public facility than schemes targeting the poorest women. Both types of schemes increased the probability of receiving postnatal care, but the increase was significant only for non-poor women. Universal, but not targeted, voucher schemes significantly increased the probability of receiving antenatal care. CONCLUSION: Voucher schemes increased deliveries in health centres and, to a lesser extent, improved antenatal and postnatal care. However, schemes that targeted poorer women did not appear to be efficient since these women were more likely than less poor women to be encouraged to give birth in a public health-care facility, even with universal voucher schemes.

Persistent inequalities in child undernutrition: evidence from 80 countries, from 1990 to today.

BACKGROUND: Global progress in reducing the burden of undernutrition tends to be measured at the population level. It has been hypothesized that population-level improvements may mask widening socioeconomic inequalities, but little attempt has been made to assess whether this is true. METHODS: Original data from 131 demographic health surveys and 48 multiple indicator cluster surveys from 1990 to 2011 were used to examine trends in socioeconomic inequalities in stunting and underweight, as well as the relationship between changes in prevalence and changes in inequality, in 80 countries. Socioeconomic inequality is measured using the corrected concentration index. RESULTS: Countries with a higher prevalence of stunting tend to have larger socioeconomic inequalities in stunting (Spearman rank correlation = -0.27 P = 0.014). In most countries, there has been no change in inequality in stunting: in 31 out of 53, the 90% confidence intervals around the changes overlap the zero value. In the remaining 22, there was a reduction in inequality in 11 and an increase in 11. The distributional patterns underlying the summary inequality statistics vary considerably across countries, but in most there have been considerable gains to the poorest quintile. CONCLUSIONS: Reductions in the prevalence of undernutrition have generally not been accompanied by widening inequalities. However, inequalities have also not been narrowing. Rather, the picture is one of a strong persistence of existing inequalities. In addition, there are different distributional patterns underlying changes in the summary indices of inequality which will need to be taken into consideration in designing programmes to reach the poor.

Healthcare-seeking behaviour in rural Ethiopia: evidence from clinical vignettes.

OBJECTIVES: To investigate the determinants of healthcare-seeking behaviour using five context-relevant clinical vignettes. The analysis deals with three issues: whether and where to seek modern care and when to seek care. SETTING: This study is set in 96 villages located in four main regions of Ethiopia. The participants of this study are 1632 rural households comprising 9455 individuals. PRIMARY AND SECONDARY OUTCOME MEASURES: Probability of seeking modern care for symptoms related to acute respiratory infections/pneumonia, diarrhoea, malaria, tetanus and tuberculosis. Conditional on choosing modern healthcare, where to seek care (health post, health centre, clinic and hospital). Conditional on choosing modern healthcare, when to seek care (seek care immediately, the next day, after 2 days, between 3 days to 1 week, a week or more). RESULTS: We find almost universal preference for modern care. Foregone care ranges from 0.6% for diarrhoea to 2.5% for tetanus. There is a systematic relationship between socioeconomic status and choice of providers mainly for adult-related conditions with households in higher consumption quintiles more likely to seek care in health centres, private/Non-Government Organization (NGO) clinics as opposed to health posts. Delays in care-seeking behaviour are apparent mainly for adult-related conditions and among poorer households. CONCLUSIONS: The analysis suggests that the lack of healthcare utilisation is not driven by the inability to recognise health problems or due to a low perceived need for modern care.

Does the distribution of healthcare utilization match needs in Africa?

An equitable distribution of healthcare use, distributed according to people's needs instead of ability to pay, is an important goal featuring on many health policy agendas worldwide. However, relatively little is known about the extent to which this principle is violated across socio-economic groups in Sub-Saharan Africa (SSA). We examine cross-country comparative micro-data from 18 SSA countries and find that considerable inequalities in healthcare use exist and vary across countries. For almost all countries studied, healthcare utilization is considerably higher among the rich. When decomposing these inequalities we find that wealth is the single most important driver. In 12 of the 18 countries wealth is responsible for more than half of total inequality in the use of care, and in 8 countries wealth even explains more of the inequality than need, education, employment, marital status and urbanicity together. For the richer countries, notably Mauritius, Namibia, South Africa and Swaziland, the contribution of wealth is typically less important. As the bulk of inequality is not related to need for care and poor people use less care because they do not have the ability to pay, healthcare utilization in these countries is to a large extent unfairly distributed. The weak average relationship between need for and use of health care and the potential reporting heterogeneity in self-reported health across socio-economic groups imply that our findings are likely to even underestimate actual inequities in health care. At a macro level, we find that a better match of needs and use is realized in those countries with better governance and more physicians. Given the absence of social health insurance in most of these countries, policies that aim to reduce inequities in access to and use of health care must include an enhanced capacity of the poor to generate income.

Coping with the economic consequences of ill health in Indonesia.

We assess the economic risk of ill health for households in Indonesia and the role of informal coping strategies. Using household panel data from the Indonesian socio-economic household survey (Susenas) for 2003 and 2004, and applying fixed effects Poisson models, we find evidence of economic risk from illness through medical expenses. For the poor and the informal sector, ill health events impact negatively on income from wage labour, whereas for the non-poor and formal sector, it is income from self-employed business activities which is negatively affected. However, only for the rural population and the poor does this lead to a decrease in consumption, whereas the non-poor seem to be able to protect current household spending. Borrowing and drawing on family network and buffers, such as savings and assets, seem to be key informal coping strategies for the poor, which may have negative long-term effects. While these results suggest scope for public intervention, the economic risk from income loss for the rural poor is beyond public health care financing reforms. Rather, formal sector employment seems to be a key instrument for financial protection from illness, by also reducing income risk.

Effects of NCMS on access to care and financial protection in China.

The introduction of the New Cooperative Medical Scheme (NCMS) in rural China has been the most rapid and dramatic extension of health insurance coverage in the developing world in this millennium. The literature to date has mainly used the uneven rollout of NCMS across counties as a way of identifying its effects on access to care and financial protection. This study exploits the cross-county variation in NCMS generosity in 2006 and 2008 in the Ningxia and Shandong provinces to estimate the effect of coverage generosity on utilization and financial protection. Our results confirm earlier findings of NCMS being effective in increasing access to care but not in increasing financial protection. In addition, we find NCMS enrollees to be sensitive to the price incentives set in the NCMS design when choosing their provider and providers to respond by increasing prices and/or providing more expensive care.
