Does maternal health voucher scheme have association with distance inequality in maternal and newborn care utilization? Evidence from rural Bangladesh

BACKGROUND

Bangladesh has made substantial progress in maternal health. However, persistent inequities in service use undermine the achievements at the national level. In 2007, the government introduced a Maternal Health Voucher Scheme (MHVS) to reduce barriers to service utilization. The current study explores the impact of MHVS on reducing distance inequality in utilization across the maternal and newborn continuum of care (MNCoC).

METHODS

A cross-sectional survey was conducted from October'2017 to April'2018 in four selected MHVS sub-districts of Chattogram and Sylhet Divisions of Bangladesh. 2,400 women with at-least one child aged below two years were randomly selected. Both bivariate and multivariate analyses were carried out to explore the absolute and relative influence of the voucher scheme and chi-square test was used for hypothesis testing.

RESULTS

Nineteen percent of the women were MHVS beneficiaries and 23% of them lived within 5 km of the health facility. Among the beneficiaries no significant differences were observed in the utilization of at-least 4 antenatal visits, skilled-assistance at delivery, postnatal care, and MNCoC between those living closer to the health facility and those living far away. However, a higher facility delivery rate was observed among beneficiary women living closer. By contrast, for non-beneficiaries, a significant difference was found in service use between women living closer to health facilities compared to those living further away.

CONCLUSION

The study found the use of MNCoC to be similar for all MHVS beneficiaries irrespective of their distance to health facilities whereas non-beneficiary women living further away had lower utilization rates. MHVS could have potentially reduced distance-related inequality for its beneficiaries. However, despite the provision of transport incentives under MHVS the reduction in inequality in facility delivery was limited. We propose a revision of the transportation incentive adjusting for distance, geographical remoteness, road condition, and transport cost to enhance the impact of MHVS.

Effect of national immunisation campaigns with oral polio vaccine on all-cause mortality in children in rural northern Ghana: 20 years of demographic surveillance cohort data

Background

Studies from Guinea-Bissau and Bangladesh have shown that campaigns with oral polio vaccine (C-OPV) may be associated with 25-31% lower child mortality. Between 1996 and 2015, Ghana had 50 national C-OPVs and numerous campaigns with vitamin A supplementation (VAS), and measles vaccine (MV). We investigated whether C-OPVs had beneficial non-specific effects (NSEs) on child survival in northern Ghana.

Methods

We used data from a health and demographic surveillance system in the Navrongo Health Research Centre in rural northern Ghana to examine mortality from day 1-5 years of age. We used Cox models with age as underlying time scale to calculate hazard ratios (HR) for the time-varying covariate "after-campaign" mortality versus "before-campaign" mortality, adjusted for temporal change in mortality, other campaign interventions and stratified for season at risk.

Findings

From 1996 to 2015, 75,610 children were followed for 280,156 person-years between day 1 and 5 years of age. In initial analysis, assuming a common effect across all ages, we did not find that OPV-only campaigns significantly reduced all-cause mortality, the HR being 0.96 (95% CI: 0.88-1.05). However, we subsequently found the HR differed strongly by age group, being 0.92 (0.75-1.13), 1.29 (1.10-1.51), 0.79 (0.66-0.94), 0.67 (0.53-0.86) and 1.03 (0.78-1.36) respectively for children aged 0-2, 3-5, 6-8, 9-11 and above 12 months of age (p < 0.001). Triangulation of the evidence from this and previous studies suggested that increased frequency of C-OPVs and a different historical period could explain these results.

Interpretation

In Ghana, C-OPVs had limited effects on overall child survival. However, triangulating the evidence suggested that NSEs of C-OPVs depend on age of first exposure and routine vaccination programs. C-OPVs had beneficial effects for children that were not exposed before 6 months of age. These non-specific effects of OPV should be exploited to further reduce child mortality.

The risk of miscarriage is associated with ambient temperature: evidence from coastal Bangladesh

Background

Exposure to high ambient temperature is reported to cause adverse pregnancy outcomes. However, considering myriad temperature and climatic conditions as well as different contextual factors, the paucity of studies from the developing regions impedes the development of a clear understanding of the heat-pregnancy outcome relationship.

Materials and methods

This study was conducted in Chakaria, a coastal region of Bangladesh, where International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) administers a health and demographic surveillance system (HDSS). The surveillance workers visit the households every three months as a part of the routine surveillance activity. Between 2012 and 2020, the surveillance workers documented histories of 23,482 pregnancies among 13,376 women and the women were followed up for their pregnancy outcomes. The temperature records were obtained from the Bangladesh Meteorological Department's weather station at Cox's Bazar. The dates of pregnancy outcome were linked with the daily average temperature on the day of pregnancy outcome. A logistic regression model was employed to examine the relationship between temperature and the incidence of miscarriage.

Results

Out of 23,482 pregnancy outcomes, 3.7% were induced abortions. Among the remaining 22,624 pregnancy outcomes, 86.2% were live births, 10.7% were miscarriages and 3.1% were stillbirths. Miscarriages peaked between 8-14 weeks of gestation and varied according to temperature. For women exposed to temperatures between 28°C and 32°C, the risk of miscarriage was 25% greater (adjusted OR 1.25, 95% CI 1.07-1.47) compared to those exposed to temperatures from 16°C to 21°C.

Conclusion

The study establishes a connection between miscarriage and high ambient temperatures in a coastal region of Bangladesh. Implementing timely and appropriate adaptation strategies to prevent miscarriages is of paramount importance for a densely populated country like Bangladesh.

Spatial pattern and influential factors for early marriage: evidence from Bangladesh Demographic Health Survey 2017-18 data

BACKGROUND

Early marriage is highly prevalent in Bangladesh. It is linked with a range of adverse outcomes, including maternal and child mortality. However, research on regional variations and factors associated with early marriage is scarce in Bangladesh. This study aimed to explore the geographical variations and predictors of early marriage in Bangladesh.

METHODS

Data of women aged 20-24 in the Bangladesh Demographic and Health Survey 2017-18 were analysed. The occurrence of early marriage was the outcome variable. Explanatory variables were several individual-, household- and community-level factors. Geographical hot spots and cold spots of early marriage were first determined using Global Moran's I statistic. Multilevel mixed-effect Poisson regression was used to determine the association of early marriage with individual-, household-, and community-level factors.

RESULTS

Almost 59% of women aged 20-24 reported they were married before reached 18. The hotspots of early marriage were mainly concentrated in Rajshahi, Rangpur and Barishal, and the cold spots were in Sylhet and Chattogram divisions. The prevalence of early marriage was lower among higher educated (adjusted prevalence ratio (aPR): 0.45; 95% CI: 0.40, 0.52), and non-Muslim women (aPR: 0.89; 95% CI: 0.79, 0.99) than their counterparts. Higher community-level poverty was significantly associated with early marriage (aPR, 1.16; 95% CI: 1.04, 1.29).

CONCLUSION

The study concludes that promoting girls' education, awareness-building programs about the adverse effects of early marriage and proper application of the child marriage restraint act, particularly in disadvantaged communities are recommended.

Environmental reservoirs of the drug-resistant pathogenic yeast Candida auris

Candia auris is an emerging human pathogenic yeast; yet, despite phenotypic attributes and genomic evidence suggesting that it probably emerged from a natural reservoir, we know nothing about the environmental phase of its life cycle and the transmission pathways associated with it. The thermotolerant characteristics of C. auris have been hypothesised to be an environmental adaptation to increasing temperatures due to global warming (which may have facilitated its ability to tolerate the mammalian thermal barrier that is considered a protective strategy for humans against colonisation by environmental fungi with pathogenic potential). Thus, C. auris may be the first human pathogenic fungus to have emerged as a result of climate change. In addition, the release of antifungal chemicals, such as azoles, into the environment (from both pharmaceutical and agricultural sources) is likely to be responsible for the environmental enrichment of resistant strains of C. auris; however, the survival and dissemination of C. auris in the natural environment is poorly understood. In this paper, we critically review the possible pathways through which C. auris can be introduced into the environment and evaluate the environmental characteristics that can influence its persistence and transmission in natural environments. Identifying potential environmental niches and reservoirs of C. auris and understanding its emergence against a backdrop of climate change and environmental pollution will be crucial for the development of effective epidemiological and environmental management responses.

Health system impact of COVID-19 on urban slum population of Bangladesh: a mixed-method rapid assessment study

OBJECTIVE

We aimed to rapidly assess the health system impact of COVID-19 in the urban slums of Bangladesh.

DESIGN

Setting and participantsA cross-sectional survey among 476 households was conducted during October-December 2020 in five selected urban slums of Dhaka North, Dhaka South and Gazipur City Corporation. In-depth interviews with purposively selected 22 slum dwellers and key informant interviews with 16 local healthcare providers and four policymakers and technical experts were also conducted.

OUTCOME MEASURES

Percentage of people suffering from general illness, percentage of people suffering from chronic illness, percentage of people seeking healthcare, percentage of people seeking maternal care, health system challenges resulting from COVID-19.

RESULTS

About 12% of members suffered from general illness and 25% reported chronic illness. Over 80% sought healthcare and the majority sought care from informal healthcare providers. 39% of the recently delivered women sought healthcare in 3 months preceding the survey. An overall reduction in healthcare use was reported during the lockdown period compared with prepandemic time. Mismanagement and inefficient use of resources were reported as challenges of health financing during the pandemic. Health information sharing was inadequate at the urban slums, resulting from the lack of community and stakeholder engagement (51% received COVID-19-related information, 49% of respondents knew about the national hotline number for COVID-19 treatment). Shortage of human resources for health was reported to be acute during the pandemic, resulting from the shortage of specialist doctors and uneven distribution of health workforce. COVID-19 test was inadequate due to the lack of adequate test facilities and stigma associated with COVID-19. Lack of strong leadership and stakeholder engagement was seen as the barriers to effective pandemic management.

CONCLUSION

The findings of the current study are expected to support the government in tailoring interventions and allocating resources more efficiently and timely during a pandemic.

Anxiety and Insomnia Among Urban Slum Dwellers in Bangladesh: The Role of COVID-19 and Its Associated Factors

Background: Although mental health is an important part of health and wellbeing, very little is known about the impact of the COVID-19 pandemic on the mental health of marginalized communities like urban slum dwellers. Our study estimated the prevalence of generalized anxiety disorder and insomnia among the residents of the informal settlements of Dhaka, Bangladesh, during the COVID-19 pandemic. Methods: A cross-sectional phone-based survey was conducted from October to November 2020 among adult residents of five informal settlements of Dhaka city randomly chosen from an existing Urban Health and Demographic Surveillance Systems (UHDSS) run by icddr,b. Data on Generalized Anxiety Disorder-7 (GAD-7) and Insomnia Severity Index (ISI) were collected. A multinomial logistic regression was performed to assess the associated factors of anxiety and insomnia. Results: Of the total 586 participants, the prevalence of mild to severe anxiety and insomnia were 53% and 43%, respectively. As per the multinomial regression analysis, participants with mild anxiety were significantly more likely to be older (>50 years) and afraid of COVID-19 infection. Likewise, participants with moderate/severe anxiety were significantly more likely to share less household facilities (e.g., toilet, kitchen, water) (OR: 2.23; 95% CI: 1.31-3.79), to have difficulties in food availability (OR: 2.76; 95% CI: 1.10-6.93), to be afraid of self (OR: 5.27; 95% CI: 2.82-9.88), and to worry about the family members (OR: 2.26; 95% CI: 1.23-4.17) getting infected. Participants with mild insomnia were significantly more likely to share fewer household facilities and be afraid of being infected with COVID-19 infection. Moreover, participants with moderate/severe insomnia were significantly more likely to be female (OR: 1.90; 95% CI: 1.02-3.56), to receive food aid (OR: 0.50; 95% CI: 0.29-0.88), to be afraid of self (OR: 3.85; 95% CI: 1.81-8.19), and to worry about someone like friends or neighbors (OR: 2.45; 95% CI: 1.07-5.58) getting infected with COVID-19. Conclusions: We found elevated prevalence of both anxiety and insomnia among the urban poor of Bangladesh in the context of COVID-19. This indicates the importance of integrating mental health in the mitigation and recovery efforts related to similar crises for the urban poor in the future.

Insights Into Excess Mortality During the First Months of the COVID-19 Pandemic From a Rural, Demographic Surveillance Site in Bangladesh

Background: Coronavirus disease 2019 (COVID-19) has spread globally, and the government of each affected country is publishing the number of deaths every day. This official figure is an underestimate as it excludes anybody who did not die in a hospital, who did not test positive, who had a false result, or those who recovered on their own without a test.

Objective: This study aimed to measure the community level excess mortality using health and demographic surveillance in a rural area of Bangladesh.

Method: The study was conducted in Matlab, in a rural area of Bangladesh, with a Health and Demographic Surveillance System (HDSS) covering a population of 239,030 individuals living in 54,823 households in 142 villages. We examined the mortality in January-April from 2015 to 2020 and compared the mortality in 2020 with the historical trend of 2015–2019. Between 2015 and 2020, we followed 276,868 people until migration or death, whichever occurred first. We analyzed mortality using crude mortality rate ratio (MRR) and adjusted MRR (aMRR) from a Cox proportional hazard model. Mortality was analyzed according to age, sex, and period.

Results: During follow-up, 3,197 people died. The mortality rate per 1,000 person-years increased from 10 in 2019 to 12 in 2020. Excess mortality was observed among the elderly population (aged 65 years and above). The elderly mortality rate per 1,000 person-years increased from 80 in 2019 to 110 in 2020, and the aMRR was 1.40 (95% CI: 1.19–1.64). Although an increasing tendency in mortality was observed between 2015 and 2019, it was statistically insignificant.

Conclusions: The study reported a 28% increase in excess deaths among the elderly population during the first months of the pandemic. This all-cause mortality estimation at the community level will urge policymakers, public health professionals, and researchers to further investigate the causes of death and the underlying reasons for excess deaths in the older age-group.

National immunisation campaigns with oral polio vaccine may reduce all-cause mortality: Analysis of 2004-2019 demographic surveillance data in rural Bangladesh

BACKGROUND

West African studies have suggested that national immunisation campaigns with oral polio vaccine (C-OPV) may non-specifically reduce all-cause child mortality rate by 15-25%. We investigated whether C-OPVs had similar non-specific effects in rural Bangladesh from 2004 to 2019.

METHODS

Chakaria, is a health and demographic surveillance system (HDSS) in Southern Bangladesh. From 2004-2011 the HDSS covered a random sample of households; from 2012 to 2019 it covered a random sample of villages. Using Cox proportional hazards models, we calculated hazard ratios (HR) comparing mortality for children under 3 years of age after C-OPV versus before C-OPV to assess the effect of receiving a C-OPV. We allowed for different baseline hazard function in the two periods (2004-2011, 2012-2019), with separate models for each period.

FINDINGS

There were 768 deaths (2.1%) amongst 36,176 children. The HR after C-OPV was 0.69 (95% confidence interval: 0.52-0.90). National campaigns providing vitamin A or measles vaccine did not have similar effects. Each additional dose of C-OPV was associated with a reduction in the mortality rate by 6% (-2 to 13%). The number needed to treat with C-OPV to save one life between 0 and 35 months of age was 88 (81-96).

INTERPRETATION

This is the fourth study to show that C-OPV has beneficial non-specific effects on child survival. All studies have shown a beneficial effect of C-OPV on child health. Stopping OPV as planned after polio eradication without any mitigation plan could have detrimental effects for overall child health in low-income countries.

FUNDING

The Chakaria HDSS was funded by international sponsors. No sponsor had any influence on the preparation of the article.

A place-based analysis of COVID-19 risk factors in Bangladesh urban slums: a secondary analysis of World Bank microdata

BACKGROUND

There is a lack of research investigating the confluence of risk factors in urban slums that may make them accelerators for respiratory, droplet infections like COVID-19. Our working hypothesis was that, even within slums, an inverse relationship existed between living density and access to shared or private WASH facilities.

METHODS

In an exploratory, secondary analysis of World Bank, cross-sectional microdata from slums in Bangladesh we investigated the relationship between intra-household population density (crowding) and access to private or shared water sources and toilet facilities.

RESULTS

The analysis showed that most households were single-room dwellings (80.4%). Median crowding ranged from 0.55 m² per person up to 67.7 m² per person. The majority of the dwellings (83.3%), shared both toilet facilities and the source of water, and there was a significant positive relationship between crowding and the use of shared facilities.

CONCLUSION

The findings highlight the practical constraints on implementing, in slums, the conventional COVID19 management approaches of social distancing, regular hand washing, and not sharing spaces. It has implications for the management of future respiratory epidemics.

Do community scorecards improve utilisation of health services in community clinics: experience from a rural area of Bangladesh

Background

The government of Bangladesh initiated community clinics (CC) to extend the reach of public health services and these facilities were planned to be run through community participation. However, utilisation of CC services is still very low. Evidence indicates community score card is an effective tool to increase utilisation of services from health facility through regular interface meeting between service providers and beneficiary. We investigated whether community scorecards (CSC) improve utilisation of health services provided by CCs in rural area of Bangladesh.

Methods

This study was conducted from December 2017 to November 2018. Three intervention and three control CCs were selected from Chakaria, a rural sub-district of Bangladesh. CSC was introduced with the Community Groups and Community Support Groups in intervention CCs between January to October 2018. Data were collected through observation of CCs during operational hours, key informant interviews, focus group discussions, and from DHIS2. Utilisation of CC services was compared between intervention and control areas, pre and post CSC intervention.

Results

Post CSC intervention, community awareness about CC services, utilisation of clinic operational hours, and accountability of healthcare providers have increased in the intervention CCs. Utilisation of primary healthcare services including family planning services, antenatal care, postnatal care and basic health services have significantly improved in intervention CCs.

Conclusion

CSC is an effective tool to increase the service utilization provided by CCs by ensuring community awareness and participation, and service providers’ accountability. Policy makers and concerned authorities may take necessary steps to integrate community scorecard in the health system by incorporating it in CCs.

Diphtheria-Tetanus-Pertussis (DTP) Vaccine Is Associated With Increased female-Male Mortality. Studies of DTP administered before and after measles vaccine

Background

The third dose of diphtheria-tetanus-pertussis vaccine (DTP3) is used to monitor immunization programs. DTP has been associated with higher female mortality.

Methods

We updated previous literature searches for DTP studies of mortality by sex. We examined the female/male (F/M) mortality rate ratio (MRR) with increasing number of doses of DTP and for subsequent doses of measles vaccine (MV) after DTP and of DTP after MV.

Results

Eight studies had information on both DTP1 and DTP3. The F/M MRR was 1.17 (95% confidence interval [CI], .88–1.57) after DTP1 and increased to 1.66 (95% CI, 1.32–2.09) after DTP3. Following receipt of MV, the F/M MRR declined to 0.63 (95% CI, .42–.96). In 11 studies the F/M MRR increased to 1.73 (95% CI, 1.33–2.27) when DTP-containing vaccine was administered after MV.

Conclusions

F/M MRR increased with increasing doses of DTP. After MV, girls had lower mortality than boys. With DTP after MV, mortality increased again for girls relative to boys. No bias can explain these changes in F/M MRR. DTP does not improve male survival substantially in situations with herd immunity to pertussis and higher F/M MRR after DTP may therefore reflects an absolute increase in female mortality.

Penta is associated with an increased female-male mortality ratio: cohort study from Bangladesh

Diphtheria-tetanus-pertussis (DTP) vaccine may be associated with excess female deaths. There are few studies of possible nonspecific effects of the DTP-containing vaccine Penta (DTP-hepatitis B-Haemophilus influenzae type b). We therefore investigated whether Penta vaccinations were associated with excess female deaths in rural Bangladesh. Between June 29, 2011 and April 20, 2016, we examined the mortality rates of 7644 children followed between 6 weeks and 9 months of age. We analyzed mortality using crude mortality rate ratio (MRR) and age-adjusted MRR (aMRR) from a Cox proportional hazards model. Mortality was analyzed according to sex, number of doses of Penta, and the order in which BCG and Penta were administered. During follow-up, 43 children died. For children who were only BCG vaccinated (BCG-only), the adjusted F/M MRR was 0.47 (0.09-2.48). However, among children who had Penta as their most recent vaccination, the adjusted F/M MRR was 9.91 (1.16-84.44). Hence, the adjusted F/M MRR differed significantly for BCG-only and for Penta as the most recent administered vaccination. Although the mortality rate was low in rural Bangladesh, there was a marked difference between adjusted F/M MRR's for children vaccinated with BCG-only compared with children where Penta was the most recent administered vaccination. Although usually ascribed to differential treatment and access to care, DTP-containing vaccines may be part of the explanation for the excessive female mortality reported in some regions.

Does healthcare voucher provision improve utilisation in the continuum of maternal care for poor pregnant women? Experience from Bangladesh

Background: Improving maternal health is a major development goal, with ambitious targets set for high-mortality countries like Bangladesh. Following a steep decline in the maternal mortality ratio over the past decade in Bangladesh, progress has plateaued at 196/100,000 live births. A voucher scheme was initiated in 2007 to reduce financial, geographical and institutional barriers to access for the poorest.

Objective: The current paper reports the effect of vouchers on the use of continuum of maternal care.

Methods: Cross-sectional surveys were carried out in the Chattogram and Sylhet divisions of Bangladesh in 2017 among 2400 women with children aged 0–23 months. Using Cluster analysis utilisation groups for antenatal care, facility delivery and postnatal care were formed. Clusters were regressed on voucher receipt to identify the underlying relationship between voucher receipt and utilisation of care while controlling for possible confounders.

Results: Four clusters with varying levels of utilisation were identified. A significantly higher proportion of voucher-recipients belonged to the high-utilisation cluster compared to non-voucher recipients (43.5% vs. 15.4%). For the poor voucher recipients, the probability of belonging to the high-utilisation cluster was higher compared to poor non-voucher recipients (33.3% vs. 6.8%) and the probability of being in the low-utilisation cluster was lower than poor non-voucher recipients (13.3% vs. 55.4%).

Conclusion: The voucher programme enhanced uptake of the complete continuum of maternal care and the benefits extended to the most vulnerable women. However, a lack of continued transition through the continuum of maternal care was identified. This insight can assist in designing effective interventions to prevent intermittent or interrupted care-seeking. Programmes that improve access to quality healthcare in pregnancy, childbirth and the postnatal period can have wide-ranging benefits. A coherent continuum-based approach to understanding maternal care-seeking behaviour is thus expected to have a greater impact on maternal, newborn and child health outcomes.

Socioeconomic and programmatic determinants of renewal of membership in a voluntary micro health insurance scheme: evidence from Chakaria, Bangladesh

Background: Out-of-pocket (OOP) healthcare expenditure is a major obstacle for achieving universal health coverage in low-income countries including Bangladesh. Sixty-three percent of the USD 27 annual per-capita healthcare expenditure in Bangladesh comes from individuals’ pockets. Although health insurance is a financial tool for reducing OOP, use of such tools in Bangladesh has been limited to some small-scale voluntary micro health insurance (MHI) schemes run by non-governmental organizations (NGO). The MHI, however, can orient people on health insurance concept and provide learning for product development, implementation, barriers to enrolment, membership renewal, and other operational challenges and solutions. Keeping this in mind, icddr,b in 2012 initiated a pilot MHI, Amader Shasthya, in Chakaria, Bangladesh. This paper explores the determinants of membership renewal in this scheme, which is a perpetual challenge for MHI.

Objective: Identify socioeconomic and programmatic determinants and their effects on membership renewal in a voluntary MHI scheme.

Methods: Data came from the online management information system of the scheme and Health and Demographic Surveillance System of Chakaria, covering the period February 2012–May 2015. Association between renewal and independent variables was examined using cross-tabular and logistic regression analyses.

Results: Nearly 20% of households in the catchment area ever enroled in the scheme, and 38% renewed membership over the initial 3 years of operation. Frequency of consultation with healthcare providers, benefits received, proximity of member’s residence to health facility, socioeconomic status, educational level, and age of the household head showed significant positive association with renewal of membership.

Conclusions: Villagers’ enrolment in the scheme indicated that even in poor economic and literacy conditions people can be motivated to enrol in insurance schemes. Degree of service utilization and benefits received can greatly enhance the probability of membership renewal, which can be ensured with good quality of services and ease of access.

Where girls are less likely to be fully vaccinated than boys: Evidence from a rural area in Bangladesh

BACKGROUND

Immunization is one of the most successful and effective health intervention to reduce vaccine preventable diseases for children. Recently, Bangladesh has made huge progress in immunization coverage. In this study, we compared the recent immunization coverage between boys and girls in a rural area of Bangladesh.

SETTING

The study is based on data from Chakaria Health and Demographic Surveillance System (HDSS) of icddr,b, which covers a population of 90,000 individuals living in 16,000 households in 49 villages.

METHODS

We calculated the coverage of fully immunized children (FIC) for 4584 children aged 12-23 months of age between January 9, 2012 and January 19, 2016. We analyzed immunization coverage using crude FIC coverage ratio (FCR) and adjusted FCR (aFCR) from binary regression models. The dynamic of gender inequality was examined across sociodemographic and economic conditions.

MAIN OUTCOME MEASURE

The adjusted female/male (F/M) FIC coverage ratios in various sociodemographic and economic categories.

RESULTS

Among children who lived below the lower poverty line, the F/M aFCR was 0.89 (0.84-0.94) compared to 0.98 (0.95-1.00) for children from the households above lower poverty line (p = 0.003, test for interaction). For children of mothers with no high school education, the F/M aFCR was 0.94 (0.91-0.97), whereas it was 1.00 (0.96-1.04) for children of mothers who attended high school (p = 0.04, test for interaction). The F/M aFCR was 1.01 (0.96-1.06) for first born children but 0.95 (0.93-0.98) for second or higher birth order children (p = 0.04, test for interaction).

CONCLUSIONS

Fewer girls than boys were completely vaccinated by their first birthday due to girls' lower coverage for measles vaccine. The tendency was most marked for children living below the poverty line, for children whose mothers did not attend high school, and for children of birth order two or higher. In the study setting and similar areas, sex differentials in coverage should be taken into account in ongoing immunization programmes.

Socioeconomic inequalities in under-five mortality in rural Bangladesh: evidence from seven national surveys spreading over 20 years

BACKGROUND

Socioeconomic inequality in health and mortality remains a disturbing reality across nations including Bangladesh. Inequality drew renewed attention globally. Bangladesh though made impressive progress in health, it makes an interesting case for learning. This paper examined the trends and changing pattern of socioeconomic inequalities in under-five mortality in rural Bangladesh. It also examined whether mother's education had any effect in reducing socioeconomic inequalities.

METHODS

Data from rural samples of seven Bangladesh Demographic Health Surveys, carried out so far, were used. Children born alive during 5 years preceding the surveys were included in the analysis. Univariate, bivariate and multivariate analyses were carried out.

RESULTS

Under-five mortality rate steadily declined over the years from 128/1000 in 1994 to 48 in 2014. Females had 8% lower mortality rates than males. Children of mothers with no schooling had 1.88 times higher mortality than those whose mother had six or more years of schooling. Similarly, children from low asset category households had on an average 1.17 times higher mortality rate than those from high asset category households. Inequality by mother's education disappeared in the recent years, and inequality by household socioeconomic condition persisted all through. The pattern of inequality by sex, mother's education, and household socioeconomic status was not changed statistically significantly over the years, and mothers' education did not reduce socioeconomic inequalities.

DISCUSSION

The reduction in mortality was consistent with changes in the proximate determinants of child survival in the country. Proximate determinants included maternal factors, environmental contamination, nutrient deficiency, personal illness control, and injury. Health and population programmes have been effective in increasing immunization coverage, use of ORS for managing diarrhoeal diseases, and increasing contraceptive use. Development activities on the other hand raised the literacy, especially among females, demand for modern health services, and reduction of poverty. However, socioeconomic inequality still exists in both under-five mortality and proximate determinants of child survival.

CONCLUSIONS

The socioeconomic inequality in under-five mortality is showing resistance against further reduction. An assessment of the adequacy of the existing programmes taking the proximate determinants of child survival into consideration will be useful for further improvement.

Gender differentials in readiness and use of mHealth services in a rural area of Bangladesh

BACKGROUND

Traditional gender roles result in women lagging behind men in the use of modern technologies, especially in developing countries. Although there is rapid uptake of mobile phone use in Bangladesh, investigation of gender differences in the ownership, access and use of mobile phones in general and mHealth in particular has been limited. This paper presents gender differentials in the ownership of mobile phones and knowledge of available mHealth services in a rural area of Bangladesh.

METHODS

We interviewed 4915 randomly selected respondents aged 18 years and above. Associations between gender and knowledge of available mHealth services, use of existing mHealth services and intentions to use mHealth services in the future were examined by multivariate logistic regression analysis, controlling for the effect of categorised covariates.

RESULTS

Of the 4915 respondents to the survey, 61.8% of men (1213/1964) and 34.4% of women (1015/2951) owned a mobile phone. For men, mobile phone ownership was highest among those aged 18-29 years (n = 663, 76.3%), and for women among those aged 30-39 years (n = 825, 44.7%). A higher proportion of men owned phones compared to women, irrespective of socioeconomic status (SES) as indicated by asset index (p < 0.001). Although mobile phone ownership on average was lower among women, they were more likely to share their mobile phone with their family members (19.7%) compared to men (11.6%, p < 0.001). Greater number of men were more likely to be aware of the use of mobile phones for healthcare compared to women (38.5% vs 26.5%, p < 0.001). Knowledge about available mHealth services was lower among women than men; however, intention to use mHealth services in the future was high for both genders, irrespective of age, education and socioeconomic status.

CONCLUSIONS

Compared to men, women are less likely to own a mobile phone and less aware of available mHealth services, despite high intention to use mHealth among both genders. To optimise the use of mHealth services and to achieve equity of use, uptake strategies should target women, with a focus on the poorer and less educated groups.

Health literacy in a community with low levels of education: findings from Chakaria, a rural area of Bangladesh

BACKGROUND

Health literacy (HL) helps individuals to make effective use of available health services. In low-income countries such as Bangladesh, the less than optimum use of services could be due to low levels of HL. Bangladesh's health service delivery is pluralistic with a mix of public, private and informally trained healthcare providers. Emphasis on HL has been inadequate. Thus, it is important to assess the levels of HL and service utilization patterns. The findings from this study aim to bridge the knowledge gap.

MATERIALS AND METHODS

The data for this study came from a cross-sectional survey carried out in September 2014, in Chakaria, a rural area in Bangladesh. A total of 1500 respondents were randomly selected from the population of 80,000 living in the Chakaria study area of icddr, b (International Centre for Diarrhoeal Disease Research, Bangladesh). HL was assessed in terms of knowledge of existing health facilities and sources of information on health care, immunization, diabetes and hypertension. Descriptive and cross-tabular analyses were carried out.

RESULTS

Chambers of the rural practitioners of allopathic medicine, commonly known as 'village doctors', were mentioned by 86% of the respondents as a known health service facility in their area, followed by two public sector community clinics (54.6%) and Union Health and Family Welfare Centres (28.6%). Major sources of information on childhood immunization were government health workers. Almost all of the respondents had heard about diabetes and hypertension (97.4% and 95.4%, respectively). The top three sources of information for diabetes were neighbours (85.7%), followed by relatives (27.9%) and MBBS (Bachelor of Medicine and Bachelor of Surgery) doctors (20.4%). For hypertension, the sources were neighbours (78.0%), followed by village doctors (38.2%), MBBS doctors (23.2%) and relatives (15%). The proportions of respondents who knew diabetes and hypertension control measures were 40.9% and 28.0%, respectively. More females knew about the control of diabetes (44.4% to 36.6%) and hypertension (31.1% to 24.2%) than males.

CONCLUSIONS

A low level of HL in terms of modern health service facilities, diabetes and hypertension clearly indicated the need for a systematic HL programme. The relatively high levels of literacy concerning immunization show that it is possible to enhance HL in areas with low levels of education through systematic awareness-raising programmes, which could result in higher service coverage.

Prevalence, pattern and sociodemographic differentials in smokeless tobacco consumption in Bangladesh: evidence from a population-based cross-sectional study in Chakaria

BACKGROUND

The health hazards associated with the use of smokeless tobacco (SLT) are similar to those of smoking. However, unlike smoking, limited initiatives have been taken to control the use of SLT, despite its widespread use in South and Southeast Asian countries including Bangladesh. It is therefore important to examine the prevalence of SLT use and its social determinants for designing appropriate strategies and programmes to control its use.

OBJECTIVE

To investigate the use of SLT in terms of prevalence, pattern and sociodemographic differentials in a rural area of Bangladesh.

DESIGN

Population-based cross-sectional household survey.

SETTING AND PARTICIPANTS

A total of 6178 individuals aged ≥13 years from 1753 households under the Chakaria HDSS area were interviewed during October-November 2011.

METHODS

The current use of SLT, namely sadapatha (dried tobacco leaves) and zarda (industrially processed leaves), was used as the outcome variable. The crude and net associations between the sociodemographic characteristics of respondents and the outcome variables were examined using cross-tabular and multivariable logistic regression analysis, respectively.

RESULTS

23% of the total respondents (men: 27.0%, women: 19.3%) used any form of SLT. Of the respondents, 10.4% used only sadapatha,13.6% used only zarda and 2.2% used both. SLT use was significantly higher among men, older people, illiterate, ever married, day labourers and relatively poorer respondents. The odds of being a sadapatha user were 3.5-fold greater for women than for men and the odds of being a zarda user were 3.6-fold greater for men than for women.

CONCLUSIONS

The prevalence of SLT use was high in the study area and was higher among socioeconomically disadvantaged groups. The limitation of the existing regulatory measures for controlling the use of non-industrial SLT products should be understood and discussion for developing new strategies should be a priority.

Unlocking community capability through promotion of self-help for health: experience from Chakaria, Bangladesh

BACKGROUND

People's participation in health, enshrined in the 1978 Alma Ata declaration, seeks to tap into community capability for better health and empowerment. One mechanism to promote participation in health is through participatory action research (PAR) methods. Beginning in 1994, the Bangladeshi research organization ICDDR,B implemented a project "self-help for health," to work with existing rural self-help organizations (SHOs). SHOs are organizations formed by villagers for their well-being through their own initiatives without external material help. This paper describes the project's implementation, impact, and reflective learnings.

METHODS

Following a self-help conceptual framework and PAR, the project focused on building the capacity of SHOs and their members through training on organizational issues, imparting health literacy, and supporting participatory planning and monitoring. Quarterly activity reports and process documentation were the main sources of qualitative data used for this paper, enabling documentation of changes in organizational issues, as well as the number and nature of initiatives taken by the SHOs in the intervention area. Health and demographic surveillance system (HDSS) data from intervention and comparison areas since 1999 allowed assessment of changes in health indicators over time.

RESULTS

Villagers and members of the SHOs actively participated in the self-help activities. SHO functionality increased in the intervention area, in terms of improved organizational processes and planned health activities. These included most notably in convening more regular meetings, identifying community needs, developing and implementing action plans, and monitoring progress and impact. Between 1999 and 2015, while decreases in infant mortality and increases in utilization of at least one antenatal care visit occurred similarly in intervention and comparison areas, increases in immunization, skilled birth attendance, facility deliveries and sanitary latrines were substantially more in intervention than comparison areas.

CONCLUSION

Building community capability by working with pre-existing SHOs, encouraging them to place health on their agendas, strengthening their functioning and implementation of health activities led to sustained improvements in utilization of services for over 20 years. Key elements underpinning success include efforts to build and maintain trust, ensuring social inclusion in project activities, and balancing demands for material resources with flexibility to be responsive to community needs.

Level, pattern, and determinants of polypharmacy and inappropriate use of medications by village doctors in a rural area of Bangladesh

OBJECTIVE

Village doctors, informal health care providers practicing modern medicine, are dominant health care providers in rural Bangladesh. Given their role, it is important to examine their prescription pattern and inappropriate use of medication.

METHODS

These cross-sectional study data were collected through surveys of patients seen by village doctors during 2008 and 2010 at Chakaria, a typical rural area of Bangladesh. Categorization of appropriate, inappropriate, and harmful prescriptions by disease conditions was based on guidelines defined by the World Health Organization (WHO), the United Nations Children's Fund (UNICEF), and the Government of Bangladesh. Analytical categorization of polypharmacy was defined when five or more medications were prescribed for a patient at a single visit.

FINDINGS

A total of 2,587 prescriptions were written by village doctors during the survey periods. Among the prescriptions were appropriate (10%), inappropriate (8%), combination of appropriate and inappropriate (63%), and harmful medications (19%). Village doctors with more than high school education were 53% less likely (odds ratio [OR]: 0.47, 95% confidence interval [CI]: 0.26-0.86) to give polypharmacy prescriptions than those with less than high school education. While exploring determinants of prescribing inappropriate and harmful medications, this study found that polypharmacy prescriptions were six times more likely [OR: 6.00, 95% CI: 3.88-9.29] to have harmful medications than prescriptions with <5 medications.

CONCLUSION

Village doctors' training and supervision may improve the quality of services and establish accountability for the benefit of the rural population.

How much salt do adults consume in climate vulnerable coastal Bangladesh?

BACKGROUND

Evidence from numerous studies suggests that salt intake is an important determinant of elevated blood pressure. Robust data about salt consumption among adults in Bangladesh is sparse. However, much evidence suggests saline intrusion due to sea level rise as a result of climate change exposes more than 20 million people to adverse effects of salinity through the food and water supply. The objective of our study was to assess salt consumption among adults in a coastal region of Bangladesh.

METHODS

Our study was cross sectional and conducted during October-November 2011. A single 24 hour urine was collected from 400 randomly selected individuals over 18 years of age from Chakaria, a rural, coastal area in Southeastern Bangladesh. Logistic regression was conducted to identify the determinants of high salt consumption.

RESULTS

The mean urinary sodium excretion was 115 mmol/d (6.8 g salt). Based on logistic regression using two different cutoff points (IOM and WHO), housewives and those living in the coastal area had a significantly higher probability of high salt intake compared with people who were engaged in labour-intensive occupations and who lived in hilly areas.

CONCLUSION

It is important to create awareness about the implication of excessive salt intake on health and to develop strategies for reducing salt intake that can be implemented at the community-level. A sustainable policy for salt reduction in the Bangladeshi diet should be formulated with special emphasis on coastal areas.

High concentration of childhood deaths in the low-lying areas of Chakaria HDSS, Bangladesh: findings from a spatial analysis

BACKGROUND

Despite significant reduction of childhood mortality in Bangladesh, large spatial variations persist. Identification of lower level spatial units with higher concentrations of deaths can be useful for strengthening services in these areas. This paper reports findings from a spatial analysis of deaths in Chakaria, a rural subdistrict, where a Health and Demographic Surveillance System has been in place since 1999. Chakaria is an INDEPTH member site.

METHODS

An analysis was done of 339 deaths among nearly 24,500 children under the age of five during 2005-2008. One ward, the lowest level of administrative units, was the unit of spatial analysis. Data from 24 wards were analyzed. The Discrete Poisson Probability Model was used to identify the clustering of deaths.

RESULTS

Deaths were concentrated within 12 wards located in the low-lying deltaic flood plains of the Chakaria HDSS area. The risk of death in the low-lying areas was statistically, significantly higher, 1.5 times, than the non-low-lying areas (p < 0.02).

CONCLUSION

Spatial analysis can be a useful tool for identifying high-risk mortality areas. An understanding of the risk factors prevalent in the low-lying areas can help design effective interventions to reduce mortality in these areas.

Are 'Village Doctors' in Bangladesh a curse or a blessing?

BACKGROUND

Bangladesh is one of the health workforce crisis countries in the world. In the face of an acute shortage of trained professionals, ensuring healthcare for a population of 150 million remains a major challenge for the nation. To understand the issues related to shortage of health workforce and healthcare provision, this paper investigates the role of various healthcare providers in provision of health services in Chakaria, a remote rural area in Bangladesh.

METHODS

Data were collected through a survey carried out during February 2007 among 1,000 randomly selected households from 8 unions of Chakaria Upazila. Information on health-seeking behaviour was collected from 1 randomly chosen member of a household from those who fell sick during 14 days preceding the survey.

RESULTS

Around 44% of the villagers suffered from an illness during 14 days preceding the survey and of them 47% sought treatment for their ailment. 65% patients consulted Village Doctors and for 67% patients Village Doctors were the first line of care. Consultation with MBBS doctors was low at 14%. Given the morbidity level observed during the survey it was calculated that 250 physicians would be needed in Chakaria if the patients were to be attended by a qualified physician.

CONCLUSIONS

With the current shortage of physicians and level of production in the country it was asserted that it is very unlikely for Bangladesh to have adequate number of physicians in the near future. Thus, making use of existing healthcare providers, such as Village Doctors, could be considered a realistic option in dealing with the prevailing crisis.

Smoking has declined but not for all: findings from a study in a rural area of Bangladesh

Smoking is one of the leading causes of death and two-thirds of the world's smokers live in 10 countries, including Bangladesh. This study examines the trend and differentials in smoking in Chakaria, Bangladesh. Data from 2 surveys conducted in 1994 and 2008 in Chakaria were used.

RESULTS

showed that smoking declined from 41% in 1994 to 27% in 2008. However, the decline was lower among the poor and the rate remained the same for the female illiterate. Interventions to prevent smoking need to be designed such that they are effective in disadvantaged groups and do not contribute to widening of socioeconomic inequalities in smoking prevalence and tobacco-related ill health and death.

Action monitoring for equity and gender in health

Equity and gender, despite being universal concerns for all health programmes in Bangladesh, are often missing in many of the health agenda. The health programmes fail to address these important dimensions unless these are specifically included in the planning stage of a programme and are continually monitored for progress. This paper presents the situation of equity in health in Bangladesh, innovations in monitoring equity in the use of health services in general and by the poor in particular, and impact of targeted non-health interventions on health outcomes of the poor. It was argued that an equitable use of health services might also result in enhanced overall coverage of the services. The findings show that government services at the upazila level are used by the poor proportionately more than they are in the community, while at the private facilities, the situation is reverse. Commonly-used monitoring tools, at times, are not very useful for the programme managers to know how well they are doing in reaching the poor. Use of benefit-incidence ratio may provide a quick feedback to the health facility managers about their extent of serving the poor. Similarly, Lot Quality Assurance Sampling can be an easy-to-use tool for monitoring coverage at the community level requiring a very small sample size. Although health problems are biomedical phenomena, their solutions may include actions beyond the biomedical framework. Studies have shown that non-health interventions targeted towards the poor improve the use of health services and reduce mortality among children in poor households. The study on equity and health deals with various interlocking issues, and the examples and views presented in this paper intend to introduce their importance in designing and managing health and development programmes.

Sociodemographic characteristics of tobacco consumers in a rural area of Bangladesh

Bangladesh typifies many developing countries experiencing an increasing trend in tobacco consumption. However, little is known about the general pattern of tobacco consumption and about population groups who are more prone to tobacco consumption. This paper aimed at generating knowledge on tobacco consumption, especially emphasizing the identification of sociodemographic groups who are more prone to tobacco consumption vis-à-vis tobacco-related health consequences in a remote rural area in Bangladesh. Information on the tobacco consumption status of 6,618 individuals (52.1% males, 47.9% females), aged over 15 years, was collected in 1994. Both univariate and multivariate analyses were done. Individuals were categorized as consumers if they consumed tobacco in any form at all, i.e. smoke or chew. The independent variables included various characteristics of individuals and households. Overall, 43.4% of the study subjects consumed tobacco. Males were 9.38 times more likely to consume tobacco than their female counterparts. Individuals with no education were 3.62 times more likely to consume tobacco than those who had completed six or more years of schooling, and the poor were almost twice as likely to consume tobacco than the rich. Tobacco consumption in both smoke and chewing form has been a part of household consumption in Bangladesh from time immemorial. Only aggressive anti-tobacco programmes on various fronts may salvage the vulnerable groups from the menace of tobacco consumption in Bangladesh.

Performance of the lot quality assurance sampling method compared to surveillance for identifying inadequately-performing areas in Matlab, Bangladesh

This paper compared the performance of the lot quality assurance sampling (LQAS) method in identifying inadequately-performing health work-areas with that of using health and demographic surveillance system (HDSS) data and examined the feasibility of applying the method by field-level programme supervisors. The study was carried out in Matlab, the field site of ICDDR,B, where a HDSS has been in place for over 30 years. The LQAS method was applied in 57 work-areas of community health workers in ICDDR,B-served areas in Matlab during July-September 2002. The performance of the LQAS method in identifying work-areas with adequate and inadequate coverage of various health services was compared with those of the HDSS. The health service-coverage indicators included coverage of DPT, measles, BCG vaccination, and contraceptive use. It was observed that the difference in the proportion of work-areas identified to be inadequately performing using the LQAS method with less than 30 respondents, and the HDSS was not statistically significant. The consistency between the LQAS method and the HDSS in identifying work-areas was greater for adequately-performing areas than inadequately-performing areas. It was also observed that the field managers could be trained to apply the LQAS method in monitoring their performance in reaching the target population.

Nature of domestic violence against women in a rural area of Bangladesh: implication for preventive interventions

This paper reports finding from a study carried out in a remote rural area of Bangladesh during December 2000. Nineteen key informants were interviewed for collecting data on domestic violence against women. Each key informant provided information about 10 closest neighbouring ever-married women covering a total of 190 women. The questionnaire included information about frequency of physical violence, verbal abuse, and other relevant information, including background characteristics of the women and their husbands. 50.5% of the women were reported to be battered by their husbands and 2.1% by other family members. Beating by the husband was negatively related with age of husband: the odds of beating among women with husbands aged less than 30 years were six times of those with husbands aged 50 years or more. Members of micro-credit societies also had higher odds of being beaten than non-members. The paper discusses the possibility of community-centred interventions by raising awareness about the violation of human rights issues and other legal and psychological consequences to prevent domestic violence against women.
