Social capital is associated with both risk-taking and risk-avoidance in rural Bangladesh
Throughout human evolutionary history, individuals have faced two fundamental challenges under uncertainty: deciding whether to take risks and managing risks through cooperation. While both risk-taking and social risk management have been widely studied, less attention has been given to how these two processes are linked—specifically, how risk-taking itself may be shaped by social networks. We test the “social capital buffer” hypothesis, which po…
Reciprocal exchanges across multilayered networks show an emerging patron-client system led by salaried households
Evolutionary models of social inequality suggest that status differentiation can emerge within cooperative networks through sustained asymmetric exchanges between high- and low-value resources, giving rise to patron-client relationships. From a network perspective, such asymmetric relationships take the form of multilayered reciprocity, where different types of resources are exchanged across domains. By analyzing multilayered support networks in …
Nutrition and Handgrip Strength Among Adults in Rural Matlab, Bangladesh
OBJECTIVE: Handgrip strength (HGS) provides a dynamic indicator of overall strength and physical fitness. Population-based investigations of anemia and iron deficiency as predictors of HGS are limited; most studies rely on elderly and/or clinical samples. We assessed iron deficiency, anemia, body mass index (BMI), and body fat percentage as predictors of HGS among a representative cross-sectional sample of adult residents of Matlab, Bangladesh. M…
Inverse Association Between Betel Quid Use and Diabetes in Rural Bangladesh
These models support the hypothesis that betel quid use could decrease, rather than increase, risk for diabetes in the Bangladeshi context, particularly among men (who have more frequent betel quid use than women). Heterogeneity in betel quid preparation across settings, multifactorial effects of betel quid use, and publication bias may contribute to differences between these findings and other observational studies
Religious parents receive more alloparental aid in rural Bangladesh
Researchers have long speculated about the evolutionary benefits of religiosity. One explanation for the evolution of religious ritual is that rituals signal commitment to co-religionists. As a major domain of prosocial behaviour, alloparental care – or care directed at children by non-parents – is a plausible benefit of religious signalling. The religious alloparenting hypothesis posits that parents who signal religious commitment receive greate…
Mortality perceptions in the context of the Trivers-Willard hypothesis
Targeted assessment of prevalence of zero-dose and under-immunised children in Bangladesh
Introduction Gavi, the Vaccine Alliance and the Global Immunisation Agenda 2030 have intensified their emphasis on equity, with the intent of reaching zero-dose (ZD—missing the first dose of pentavalent) and under-immunised (UI—missing the third dose of pentavalent) children and their communities. In Bangladesh, inequities in immunisation coverage continue and a country learning hub is supporting the Expanded Programme on Immunisation (EPI) with …
Marital coitus in Bangladesh in the 2010s
Background: In Bangladesh, marriage is the sole socially accepted context for sexual intimacy or coitus between partners. Over the past decade, the predictors of coitus in the country have undergone notable changes, including progress in socioeconomic conditions, health behaviours, nutritional status, and contraceptive practices. Despite these changes, there exists no empirical evidence regarding patterns of coitus in Bangladesh, leaving a critic…
Life Course Timing of Mortality Exposure and Fertility Behavior
Mortality and fertility are important, intricately linked drivers of population change. Although past demographic research has focused largely on population-level mortality rates, individual-level mortality experiences can also shape fertility. The timing of mortality exposure over the life course might distinctly shape individual-level fertility behavior, with some time periods being more sensitive than others. Using detailed data from a sample …
High wet-bulb temperatures, time allocation, and diurnal patterns of breastfeeding in Bangladeshi fisher-traders
These results highlight an important role of maternal work on infants' vulnerability to environmental stress. Dyads' ability to behaviourally compensate for extreme heat may be constrained by extended heatwaves, humidity, and economic circumstances, suggesting that climate change will likely exacerbate heat-related risks to global child health going forward
Impacts of women's work and childcare on child illness among Bangladeshi Shodagor communities
For decades, women's employment has been seen as crucial for achieving greater autonomy and empowerment for women, and for promoting better health and nutrition outcomes for children, particularly in low- and middle-income countries (LMIC). However, numerous empirical studies of the relationship between women's work and child outcomes have shown mixed results. Our study tests the assumptions of a model that suggests loss of maternal care during w…
Betel quid use is associated with anemia among both men and women in Matlab, Bangladesh
Anemia accounts for 8.8% of total disability burden worldwide. Betel quid use among pregnant women has been found to increase anemia risk. Betel quid is prepared by wrapping the betel (or areca) nut, with spices and other additions, in betel or tobacco leaf and it is chewed or placed in the mouth. We explored the association between betel quid use and anemia among men and non-pregnant women. We collected data from a random sample of women and the…
Trends in women’s height and the effect of early childbearing on height retardation
Background: Depending on race, ethnicity, and region, genetic variants determine human height by 65% to 80%, while the remaining variance of 20% to 35% is influenced by nutrition and other individual or environmental exposures in the early years of life. An improvement in nutrition and health in the early years in a population underprivileged in health and nutrition will likely increase the group's average height. Due to outstanding improvements …
Economic impacts and nutritional outcomes of the 2017 floods in B angladeshi S hodagor fishing families
OBJECTIVES: As climate change continues to increase the frequency and severity of flooding in Bangladesh and globally, it becomes increasingly critical to understand the pathways through which flooding influences health outcomes, particularly in lower-income and subsistence-based communities. We aim to assess economic pathways that link flooding to nutritional outcomes among Shodagor fishing families in Bangladesh. METHODS: We examine longitudina…
Sex differences in the care of the fetus in the mother's womb and the neonate on her lap
Valuation of sons over daughters introduces sex-biased health, economic, and socio-demographic inequalities in many societies. This study aims to examine fetus-sex differences in maternity services and sex differences in medical care for terminally ill neonates in Bangladesh, using secondary data from the Matlab Health and Demographic Surveillance System (HDSS), maintained by icddr,b since 1966 along with data from the Bangladesh Maternal Mortali…

The impact of market integration on arranged marriages in Matlab, Bangladesh
Success in marriage markets has lasting impacts on women's wellbeing. By arranging marriages, parents exert financial and social powers to influence spouse characteristics and ensure optimal marriages. While arranging marriages is a major focus of parental investment, marriage decisions are also a source of conflict between parents and daughters in which parents often have more power. The process of market integration may alter parental investmen…
Labor migration is associated with lower rates of underweight and higher rates of obesity among left-behind wives in rural Bangladesh
BACKGROUND: Among Bangladeshi men, international labor migration has increased ten-fold since 1990 and rural to urban labor migration rates have steadily increased. Labor migration of husbands has increased household wealth and redefined women's roles, which have both positively and negatively impacted the health of wives "left behind". We examined the direct and indirect effects of husband labor migration on chronic disease indicators and outcom…

Subjects Three population groups: pre-school age children (6–59 months; PSA…
Consanguineous Marriage, Kinship Ecology, and Market Transition
This paper uses the framework of intensive and extensive kinship systems to organize and understand a large body of research on consanguineous marriage across cultures, particularly studies in demography and development that document decreasing consanguineous marriage with market integration. We argue that while agricultural subsistence is often associated with intensive kinship systems, including kin marriages, increasing engagement in a market …
Causes of death in two rural demographic surveillance sites in Bangladesh, 2004–2010
OBJECTIVE: Population-based information on causes of death (CoD) by age, sex, and area is critical for countries with limited resources to identify and address key public health issues. This study analysed the demographic surveillance and verbal autopsy (VA) data to estimate age- and sex-specific mortality rates and cause-specific mortality fractions in two well-defined rural populations within the demographic surveillance system in Abhoynagar an…
Cause-specific childhood mortality in Africa and Asia
BACKGROUND: Childhood mortality, particularly in the first 5 years of life, is a major global concern and the target of Millennium Development Goal 4. Although the majority of childhood deaths occur in Africa and Asia, these are also the regions where such deaths are least likely to be registered. The INDEPTH Network works to alleviate this problem by collating detailed individual data from defined Health and Demographic Surveillance sites. By re…

Demographic events and economic conditions of rural households in Bangladesh
Demographic events, such as death of adults and marriage of children, place a heavy burden on household economy, while economic and labour migration may lessen the burden. This study examined the effects of demographic events on economic condition of rural households in Bangladesh. Household possessions of durable assets in the Matlab demographic surveillance area in 1996 and 2005 were used to calculate asset scores, a proxy for long-term economi…
Effect of Maternal Mortality on Survival of Under-Five Children
With regards to children who are born shortly before their mother's death (index), the cumulative proportion of survival up to 60 months of age was significantly lower (0.39 vs. 0.81) than those born just before the last child (penultimate) of the same mother. Such a difference is mainly due to high mortality in the first six months of age. Over the period between 1974 and 2005, survival improved among the penultimate but not the index children. …

Birth spacing and infant and early childhood mortality in a high fertility area of Bangladesh
To examine the effects of birth spacing on early childhood mortality, 3729 singleton births in 1983–84 were followed for 3 years in rural Bangladesh. Logistic regression analyses were used to assess whether the survival of older siblings modifies the effect of preceding birth intervals and to see if the effects of preceding and succeeding birth intervals are inter-related, controlling for the effects of sex of the child, mother's age and househol…
Infant and Child Mortality in Bangladesh
This study examines whether mortality of two adjacent siblings in families is age-specific and is modified by the MCH-FP programme and fertility and mortality declines in Matlab, Bangladesh, using data for singleton births during 1977-78, 1985-86 and 1989-90 in the treatment (MCH-FP) and comparison areas. Logistic regression was used to estimate the net effects of survival status of elder siblings on mortality of younger siblings in the neonatal,…
Teenage Motherhood and Infant Mortality in Bangladesh
Nuptiality norms in rural Bangladesh favour birth during the teenage years. An appreciable proportion of teenage births are, in fact, second births. This study examines the relationship between teenage fertility and high infant mortality. It is hypothesized that if physiological immaturity is responsible, then the younger the mother, the higher would be the mortality risk, and the effect of mother's ‘teenage’ on mortality in infancy, particularly…
Determinants of divorce in a traditional Muslim community in Bangladesh
This study examines the effects of spousesâ prior marital status and socio-demographic characteristics on the risk of divorce of 1762 Muslim marriages recorded in 1982-83 in Teknaf, Bangladesh. Grooms' prior marital status was categorized into never ma
The Effect of Divorce on Infant Mortality in a Remote Area of Bangladesh
The process of divorce is usually lengthy and hazardous, and can start quarrels that can lead to the abuse of women and their children. This study examines the effects of divorce on neonatal and postneonatal mortality of babies born before and after divorce in Teknaf, a remote area of Bangladesh. The longitudinal demographic surveillance system (DSS) followed 1762 Muslim marriages in 1982–83 for 5 years to record divorce, deaths of spouse, emigra…

Unmet Need for Additional Medical Care for Sick Children in Mother’s View in Rural Bangladesh
While a country’s health policy aims to provide health services to all who need them, very little in known about unmet need for additional medical care from users’ perspectives in Bangladesh. This study examined unmet medical need (defined as whether a mother felt that, to manage sickness, her child had required medical care that was not available, regardless of reasons and medical care sought) of 2123 under-15 sick children by illness and child’…
Determinants of Perceived Morbidity and Use of Health Services by Children Less Than 15 Years Old in Rural Bangladesh
Epidemiological transition in rural Bangladesh, 1986–2006
BACKGROUND: For understanding epidemiological transition, Health and Demographic Surveillance System plays an important role in developing and resource-constraint setup where accurate information on vital events (e.g. births, deaths) and cause of death is not available. METHODS: This study aimed to assess existing level and trend of causes of 18,917 deaths in Matlab, a rural area of Bangladesh, during 1986-2006 and to project future scenarios for…
Spatio-temporal patterns of under-five mortality in Matlab HDSS in rural Bangladesh
BACKGROUND: Knowledge of spatial and temporal distributions of mortality and morbidity is important to prioritise areas for adjusting the public health system where people need services most. A Health and Demographic Surveillance System (HDSS) plays an important role where accurate national vital events are not available in identifying areas and periods with excess mortality risks. METHODS: The HDSS in Matlab, a rural area of Bangladesh, provided…

The association of meteorological factors and mortality in rural Bangladesh, 1983–2009
INTRODUCTION: While the association of weather and mortality has been well documented for moderate climate zones, little is known about sub-tropical zones, particularly Bangladesh. This study aims to assess the short-term relationship of temperature and rainfall on daily mortality after controlling for seasonality and time-trends. The study used data from Matlab, Bangladesh, where a rigorous health and demographic surveillance system (HDSS) has b…
The association of weather and mortality in Bangladesh from 1983–2009
INTRODUCTION: The association of weather and mortality have not been widely studied in subtropical monsoon regions, particularly in Bangladesh. This study aims to assess the association of weather and mortality (measured with temperature and rainfall), adjusting for time trend and seasonal patterns in Abhoynagar, Bangladesh. MATERIAL AND METHODS: A sample vital registration system (SVRS) was set up in 1982 to facilitate operational research in fa…
Health and demographic surveillance systems
BACKGROUND: Migration is difficult to measure because it is highly repeatable. Health and Demographic Surveillance Systems (HDSSs) provide a unique opportunity to study migration as multiple episodes of migration are captured over time. A conceptual framework is needed to show the public health implications of migration. OBJECTIVE/DESIGN: Research conducted in seven HDSS centres [International Network for the Demographic Evaluation of Populations…

HIV/Aids-related mortality in Africa and Asia
BACKGROUND: As the HIV/AIDS pandemic has evolved over recent decades, Africa has been the most affected region, even though a large proportion of HIV/AIDS deaths have not been documented at the individual level. Systematic application of verbal autopsy (VA) methods in defined populations provides an opportunity to assess the mortality burden of the pandemic from individual data. OBJECTIVE: To present standardised comparisons of HIV/AIDS-related m…
Pregnancy-related mortality in Africa and Asia
BACKGROUND: Women continue to die in unacceptably large numbers around the world as a result of pregnancy, particularly in sub-Saharan Africa and Asia. Part of the problem is a lack of accurate, population-based information characterising the issues and informing solutions. Population surveillance sites, such as those operated within the INDEPTH Network, have the potential to contribute to bridging the information gaps. OBJECTIVE: To describe pat…
Mortality from external causes in Africa and Asia
BACKGROUND: Mortality from external causes, of all kinds, is an important component of overall mortality on a global basis. However, these deaths, like others in Africa and Asia, are often not counted or documented on an individual basis. Overviews of the state of external cause mortality in Africa and Asia are therefore based on uncertain information. The INDEPTH Network maintains longitudinal surveillance, including cause of death, at populatio…
Adult non-communicable disease mortality in Africa and Asia
BACKGROUND: Mortality from non-communicable diseases (NCDs) is a major global issue, as other categories of mortality have diminished and life expectancy has increased. The World Health Organization's Member States have called for a 25% reduction in premature NCD mortality by 2025, which can only be achieved by substantial reductions in risk factors and improvements in the management of chronic conditions. A high burden of NCD mortality among muc…
Malaria mortality in Africa and Asia
BACKGROUND: Malaria continues to be a major cause of infectious disease mortality in tropical regions. However, deaths from malaria are most often not individually documented, and as a result overall understanding of malaria epidemiology is inadequate. INDEPTH Network members maintain population surveillance in Health and Demographic Surveillance System sites across Africa and Asia, in which individual deaths are followed up with verbal autopsies…
Cause-specific mortality in Africa and Asia
BACKGROUND: Because most deaths in Africa and Asia are not well documented, estimates of mortality are often made using scanty data. The INDEPTH Network works to alleviate this problem by collating detailed individual data from defined Health and Demographic Surveillance sites. By registering all deaths over time and carrying out verbal autopsies to determine cause of death across many such sites, using standardised methods, the Network seeks to …
