Progress towards the Millennium Development Goals (MDGs) has been uneven. Inequalities in child health are large and effective interventions rarely reach the most in need. Little is known about how to reduce these inequalities. We describe and explain the equity impact of a women's group intervention in India that strongly reduced the neonatal mortality rate (NMR) in a cluster-randomised trial. We conducted secondary analyses of the trial data, obtained through prospective surveillance of a population of 228,186. The intervention effects were estimated separately, through random effects logistic regression, for the most and less socio-economically marginalised groups. Among the most marginalised, the NMR was 59% lower in intervention than in control clusters in years 2 and 3 (70%, year 3); among the less marginalised, the NMR was 36% lower (35%, year 3). The intervention effect was stronger among the most than among the less marginalised (P-value for difference = 0.028, years 2-3; P-value for difference = 0.009, year 3). The stronger effect was concentrated in winter, particularly for early NMR. There was no effect on the use of health-care services in either group, and improvements in home care were comparable. Participatory community interventions can substantially reduce socio-economic inequalities in neonatal mortality and contribute to an equitable achievement of the unfinished MDG agenda.
Background We assessed the differential and sequential effects of a Government of India conditional cash transfer scheme for the socio-economically disadvantaged (Janani Suraksha Yojana; JSY) and the strengthening of the primary health centre (PHC) network to provide 24/7 obstetric care in promoting institutional deliveries.Methods This study used 7796 births from the Ballabgarh Health and Demographic Surveillance Site between April 2006 and March 2010 when both schemes were implemented in a staggered manner. The multiple baseline design took advantage of interventions separated by time and geographical zone to compute difference in differences in the rate of institutional deliveries. Logistic regression was used to estimate increases in the odds of institutional deliveries after adjustment for caste and maternal education.Results Compared with villages with poor access, institutional deliveries nearly doubled among villages with access to 24/7 delivery services; odds ratio (OR) 1.9 [95% confidence interval (CI): 1.3, 2.6]. Introduction of JSY in villages with poor access resulted in a 1.4-fold (95% CI: 1.1, 1.8) increase in institutional deliveries and a 1.1-fold (95% CI: 0.9, 1.4) increase in villages served by PHCs 24/7. However, the introduction of PHC 24/7 care to villages served by JSY doubled the rate of institutional deliveries; OR 2.1 (95% CI: 1.5, 2.8). Among the disadvantaged, institutional deliveries increased by 34.4%, compared with 24.8% among the non-disadvantaged. Introduction of PHC 24/7 care in this group increased institutional deliveries 4-fold; OR 4.2 (95% CI: 1.9, 9.0) compared with 3-fold for JSY alone; OR 3.2 (95% CI: 1.8, 5.6).Conclusions Both demand and supply side strategies are effective and promote equity. Improving service delivery in a population previously primed by demand side intervention appears to be the most useful.
BACKGROUND: Evidence from low and middle income countries (LMICs) suggests that maternal mortality is more prevalent among the poor whereas access to maternal health services is concentrated among the rich. In Bangladesh substantial inequities exist both in the use of facility-based basic obstetric care and for home births attended by skilled birth attendant. BRAC initiated an intervention on Improving Maternal, Neonatal, and Child Survival (IMNCS) in the rural areas of Bangladesh in 2008. One of the objectives of the intervention is to improve the utilization of maternal and child health care services among the poor. This study aimed to look at the impact of the intervention on utilization and also on equity of access to maternal health services.
METHODS: A quasi-experimental pre-post comparison study was conducted in rural areas of five districts comprising three intervention (Gaibandha, Rangpur and Mymensingh) and two comparison districts (Netrokona and Naogaon). Data on health seeking behaviour for maternal health were collected from a repeated cross sectional household survey conducted in 2008 and 2010.
RESULTS: Results show that the intervention appears to cause an increase in the utilization of antenatal care. The concentration index (CI) shows that this has become pro-poor over time (from CI: 0.30 to CI: 0.04) in the intervention areas. In contrast the use of ANC from medically trained providers has become pro-rich (from, CI: 0.18 to CI: 0.22). There was a significant increase in the utilisation of trained attendants for home delivery in the intervention areas compared to the comparison areas and the change was found to be pro-poor. Use of postnatal care cervices was also found to be pro-poor (from CI: 0.37 to CI: 0.14). Utilization of ANC services provided by medically trained provider did not improve in the intervention area. However, where the intervention had a positive effect on utilization it also seemed to have had a positive effect on equity.
CONCLUSIONS: To sustain equity in health care utilization, the IMNCS programme needs to continue providing free home based services. In addition to this, the programme should also continue to provide funding to bear the cost to those mothers who are not able to have the comprehensive ANC from medically trained providers.
This paper reports the findings from a quasi-experimental impact evaluation of the Safe Motherhood Promotion Project (SMPP) conducted in the Narsingdi district of Bangladesh. SMPP is a Japanese aid-funded technical cooperation project aimed at developing local capacities to tackle maternal and newborn health problems in rural areas. We assessed whether the project interventions, in particular, community-based activities under the Model Union approach, had a favorable impact on women's access to and knowledge of maternal health care during pregnancy and childbirth. The project comprises a package of interlinked interventions to facilitate safe motherhood practices at primary and secondary care levels. The primary-level activities focused on community mobilization through participatory approaches. The secondary-level activities aimed at strengthening organizational and personnel capacities for delivering emergency obstetric care (EmOC) at district and sub-district level hospitals. The project impact was estimated by difference-in-differences logistic regressions using two rounds of cross-sectional household survey data. The results showed that the project successfully increased the utilization of antenatal visits and postpartum EmOC services and also enhanced women's knowledge of danger signs during pregnancy and delivery. The project also reduced income inequalities in access to antenatal care. In contrast, we found no significant increase in the use of skilled birth attendants (SBA) in the project site. Nonetheless, community mobilization activities and the government's voucher scheme played a complementary role in promoting the use of SBA.
BACKGROUND: Colombia is one of the countries with the widest levels of socioeconomic and health inequalities. Bogotá, its capital, faces serious problems of poverty, social disparities and access to health services. A Primary Health Care (PHC) strategy was implemented in 2004 to improve health care and to address the social determinants of such inequalities. This study aimed to evaluate the contribution of the PHC strategy to reducing inequalities in child health outcomes in Bogotá.
METHODS: An ecological analysis with localities as the unit of analysis was carried out. The variable used to capture the socioeconomic status and living standards was the Quality of Life Index (QLI). Concentration curves and concentration indices for four child health outcomes (infant mortality rate (IMR), under-5 mortality rate, prevalence of acute malnutrition in children under-5, and vaccination coverage for diphtheria, pertussis and tetanus) were calculated to measure socioeconomic inequality. Two periods were used to describe possible changes in the magnitude of the inequalities related with the PHC implementation (2003 year before - 2007 year after implementation). The contribution of the PHC intervention was computed by a decomposition analysis carried out on data from 2007.
RESULTS: In both 2003 and 2007, concentration curves and indexes of IMR, under-5 mortality rate and acute malnutrition showed inequalities to the disadvantage of localities with lower QLI. Diphtheria, pertussis and tetanus (DPT) vaccinations were more prevalent among localities with higher QLI in 2003 but were higher in localities with lower QLI in 2007. The variation of the concentration index between 2003 and 2007 indicated reductions in inequality for all of the indicators in the period after the PHC implementation. In 2007, PHC was associated with a reduction in the effect of the inequality that affected disadvantaged localities in under-5 mortality (24%), IMR (19%) and acute malnutrition (7%). PHC also contributed approximately 20% to inequality in DPT coverage, favoring the poorer localities.
CONCLUSION: The PHC strategy developed in Bogotá appears to be contributing to reductions of the inequality associated with socioeconomic and living conditions in child health outcomes.
BACKGROUND: One strategic approach available to policy makers to improve the availability of reproductive and child health care supplies and services as well as the sustainability of programs is to expand the role of the private sector in providing these services. However, critics of this approach argue that increased reliance on the private sector will not serve the needs of the poor, and could lead to increases in socio-economic disparities in the use of health care services. The purpose of this study is to investigate whether the expansion of the role of private providers in the provision of modern contraceptive supplies is associated with increased horizontal inequity in modern contraceptive use.
METHODS: The study is based on multiple rounds of Demographic and Health Survey data from four selected countries (Nigeria, Uganda, Bangladesh, and Indonesia) in which there was an increase in the private sector supply of contraceptives. The methodology involves estimating concentration indices to assess the degree of inequality and inequity in contraceptive use by wealth groups across time. In order to measure inequity in the use of modern contraceptives, the study uses multivariate methods to control for differences in the need for family planning services in relation to household wealth.
RESULTS: The results suggest that the expansion of the private commercial sector supply of contraceptives in the four study countries did not lead to increased inequity in the use of modern contraceptives. In Nigeria and Uganda, inequity actually decreased over time; while in Bangladesh and Indonesia, inequity fluctuated.
CONCLUSIONS: The study results do not offer support to the hypothesis that the increased role of the private commercial sector in the supply of contraceptive supplies led to increased inequity in modern contraceptive use.
BACKGROUND: There have been few reports of differential responses to nutrition interventions in women and children from poor households. Women from poor households have greater nutritional risks and are potentially a target group for programmes. We assessed the modifying effects of household wealth on responses to micronutrient supplements in pregnancy on newborn anthropometry and perinatal mortality.
METHODS: A cluster randomized double-blind controlled trial conducted in two rural counties in northwestern China. All pregnant women in villages were randomly allocated from enrolment until delivery to daily supplementation with folic acid (control), iron/folic acid or multiple micronutrients (MMNs) with a recommended allowance of 15 vitamins and minerals. Wealth was based on a score from an inventory of household assets.
RESULTS: In the pregnant women from the poorest one-third of the households, MMN supplements significantly increased birth weight by 68 g [95% confidence interval (CI) 4-131 g], reduced low birth weight by 60% [relative risks (RRs) 0.40, 95% CI 0.21-0.78] and tended to reduce early neonatal mortality by 52% (RR 0.48, 95% CI 0.17-1.36) compared with folic acid. Iron/folic acid significantly increased the duration of gestation by 0.41 weeks (95% CI 0.18-0.65), reduced pre-term birth by 45% (RR 0.55, 95% CI 0.32-0.93) and significantly reduced early neonatal mortality by 90% (RR 0.10, 95% CI 0.01-0.79) compared with folic acid. Iron/folic acid and MMN supplements had no significant effects in women from wealthier households.
CONCLUSIONS: In rural China, women from the poorest households had the largest perinatal outcome responses to micronutrient supplementation. In these women, standard iron/folic acid provided more protection for neonatal survival than MMN supplements.
BACKGROUND: Accessibility to health services is a critical determinant for health outcome.
OBJECTIVES: To examine the association between immunisation coverage and distance to an immunisation service as well as socio-demographic and economic factors before and after the introduction of outreach immunisation services, and to identify optimal locations for outreach immunisation service points in a peri-urban area in Zambia.
METHODS: Repeated cross-sectional surveys were conducted for two groups of children born between 1999 and 2001, and between 2003 and 2005.The association between immunisation coverage for DPT3 and measles, and access distance, child sex, female headed households, and monthly household income were assessed using logistic regression analysis. Optimal locations for outreach service points were identified using GIS network analysis and genetic algorithms.
RESULTS: Before the introduction of outreach services, longer distances to the service points were associated with lower DPT3 and measles immunisation coverage (OR=0.24, 95% CI 0.10 to 0.56, p<0.01 for DPT3; and OR=0.38, 95% CI 0.17 to 0.83, p<0.05 for measles). However, access distances were not an impediment to immunisation coverage once the outreach services were introduced. The average distance to immunisation services could be decreased from 232.3 to 168.4 metres if the current 12 outreach service points were repositioned at optimal locations.
CONCLUSION: Access distance to immunisation services was a critical determinant of immunisation coverage in a peri-urban area. Intervention via outreach services played an important role in averting the risk of missing out on immunisation. Optimal location analysis has the potential to contribute to efficient decision making regarding the delivery of immunisation services.
Objective: To investigate the effect of vitamin A supplementation and BCG vaccination at birth in low birthweight neonates. Design: Randomised, placebo controlled, two by two factorial trial. Setting: Bissau, Guinea-Bissau. Participants: 1717 low birthweight neonates born at the national hospital. Intervention: Neonates who weighed less than 2.5 kg were randomly assigned to 25 000 IU vitamin A or placebo, as well as to early BCG vaccine or the usual late BCG vaccine, and were followed until age 12 months. Main outcome measure: Mortality, calculated as mortality rate ratios (MRRs), after follow-up to 12 months of age for infants who received vitamin A supplementation compared with those who received placebo. Results: No interaction was observed between vitamin A supplementation and BCG vaccine allocation (P=0.73). Vitamin A supplementation at birth was not significantly associated with mortality: the MRR of vitamin A supplementation compared with placebo, controlled for randomisation to "early BCG" versus "no early BCG" was 1.08 (95% CI 0.79 to 1.47). Stratification by sex revealed a significant interaction between vitamin A supplementation and sex (P=0.046), the MRR of vitamin A supplementation being 0.74 (95% CI 0.45 to 1.22) in boys and 1.42 (95% CI 0.94 to 2.15) in girls. When these data were combined with data from a complementary trial among normal birthweight neonates in Guinea-Bissau, the combined estimate of the effect of neonatal vitamin A supplementation on mortality was 1.08 (95% CI 0.87 to 1.33); 0.80 (95% CI 0.58 to 1.10) in boys and 1.41 (95% CI 1.04 to 1.90) in girls (P=0.01 for interaction between neonatal vitamin A and sex). Conclusions: The combined results of this trial and the complementary trial among normal birthweight neonates have now shown that, overall, it would not be beneficial to implement a neonatal vitamin A supplementation policy in Guinea-Bissau. Worryingly, the trials show that vitamin A supplementation at birth can be harmful in girls. Previous studies and future trials should investigate the possibility that vitamin A supplementation has sex differential effects. Trial registration: ClinicalTrials.gov NCT00168610.
OBJECTIVES: We evaluated the effects of the Family Health Program (FHP), a strategy for reorganization of primary health care at a nationwide level in Brazil, on infant mortality at a municipality level.
METHODS: We collected data on FHP coverage and infant mortality rates for 771 of 5561 Brazilian municipalities from 1996 to 2004. We performed a multivariable regression analysis for panel data with a negative binomial response by using fixed-effects models that controlled for demographic, social, and economic variables.
RESULTS: We observed a statistically significant negative association between FHP coverage and infant mortality rate. After we controlled for potential confounders, the reduction in the infant mortality rate was 13.0%, 16.0%, and 22.0%, respectively for the 3 levels of FHP coverage. The effect of the FHP was greater in municipalities with a higher infant mortality rate and lower human development index at the beginning of the study period.
CONCLUSIONS: The FHP had an important effect on reducing the infant mortality rate in Brazilian municipalities from 1996 to 2004. The FHP may also contribute toward reducing health inequalities.
