Changing paradigm of malnutrition among Bangladeshi women of reproductive age and gaps in national Nutrition Policies and Action Plans to tackle the emerging challenge.

Objective: The main objective of this paper is to document the changing paradigm of malnutrition in Bangladesh and estimating how this is creating an intergenerational risk. This paper also examines national policy responses to tackle the silent epidemic of double burden of malnutrition. Methods: Publicly available datasets of five Bangladesh Demographic and Health Surveys were used to see the changing paradigm of malnutrition among Bangladesh women. In addition to that, four national policies concerning, maternal and child health; and nutrition were reviewed using CDC's 2013 Policy Analytical Framework. Results: In Bangladesh, the share of ever-married women aged 15-49 who were underweight declined sharply between 2007 and 2017-2018, from 30 to 12%. In the same period, the proportion of women who were overweight or obese increased from 12 to 32%. Despite remarkable progress in reducing undernourishment among women, the share of well-nourished remained unchanged: 58% in 2007 and 56% in 2017-2018, mainly due to the shift in the dominant burden from undernutrition to overnutrition. This shift occurred around 2012-2013. Currently, in Bangladesh 0.8 million of births occur to overweight women and 0.5 million births occur to underweight women. If the current trend in malnutrition continues, pregnancies/births among overweight women will increase. Bangladesh's existing relevant policies concerning maternal health and nutrition are inadequate and mostly address the underweight spectrum of malnutrition. Discussion: Both forms of malnutrition pose a risk for maternal and child health. Underweight mothers are at risk of having anemia, antepartum/postpartum hemorrhage, and premature rupture of membranes. Maternal obesity increases the risk of perinatal complications, such as gestational diabetes, gestational hypertension, and cesarean deliveries. Currently, around 24% of the children are born to overweight/obese mothers and 15% to underweight mothers. Bangladesh should revise its national policies to address the double burden of malnutrition among women of reproductive age across pre-conception, pregnancy, and post-natal stages to ensure optimum maternal and child health.

Induced abortion after advent of fetal sex detection technology and child sex at birth.

BACKGROUND: National level Sex Ratio at Birth (SRB) is normal in Bangladesh despite its patriarchal social structures, strong son preference, and low fertility level, widely recognized as preconditions for Gender-Biased Sex Selection (GBSS). To better understand this anomaly, we examine the trend in SRB in a sub-district in Bangladesh and assess the impact of the introduction of fetal sex-detection technology and the history of induced abortion on child sex using longitudinal data. METHODS: We have used secondary data collected routinely by icddr, b's Matlab Health and Demographic Surveillance System (HDSS) between 1982 and 2018. All births occurring during this period (N = 206,390) were included in the analyses. We calculated the SRB and used multivariate logistic regression analyses to assess the likelihood of birth of a male child before and after the introduction of ultrasonogram in Matlab. RESULTS: Overall, SRB was within the natural limit (106) during 1982-2018 in Matlab. SRB among women with a history of induced abortion was 109.3 before the introduction of ultrasonography in 2001 and 113.5 - after 2001. Women's history of induced abortion prior to introduction of ultrasonogram (1982-2000) increased the likelihood of birth of a male child 1.06 times (AOR 1.06; 95% CI- 1.01-1.11). In the period after, however, this likelihood was 1.08 (AOR 1.08; 95% CI- 1.02-1.15). CONCLUSIONS: In a context with normal SRB, it was found to be skewed among women who had induced abortion. SRB was relatively more skewed among such women after the advent of ultrasonogram compared to a period without ultrasonogram. Moreover, induced abortion after introduction of fetal sex determination technology increased the likelihood of birth of a male child. These findings suggest the plausibility of GBSS in a sub-group. Further research is needed, particularly in regions with skewed SRB to examine whether GBSS is indeed a threat to Bangladesh.

Adult mortality trends in Matlab, Bangladesh: an analysis of cause-specific risks.

OBJECTIVE: With socioeconomic development, improvement in preventing and curing infectious diseases, and increased exposure to non-communicable diseases (NCDs) risk factors (eg, overweight/obesity, sedentary lifestyle), the majority of adult deaths in Bangladesh in recent years are due to NCDs. This study examines trends in cause-specific mortality risks using data from the Matlab Health and Demographic Surveillance System (HDSS). DESIGN, SETTINGS AND PARTICIPANTS: We conducted a follow-up study from 2003 to 2017 using data from Matlab HDSS, which covers a rural population of 0.24 million (in 2018) in Chandpur, Bangladesh. HDSS assessed the causes of all deaths using verbal autopsy and classified the causes using the 10th revision of the International Statistical Classification of Diseases. We examined 19 327 deaths involving 2 279 237 person-years. METHODS: We calculated annual cause-specific mortality rates and estimated adjusted proportional HRs using a Cox proportional hazards model. RESULTS: All-cause mortality risk declined over the study period among people aged 15 and older, but the risk from stroke increased, and from heart disease and cancers remained unchanged. These causes were more common among middle-aged and older people and thus bore the most burden. Mortality from causes other than NCDs-namely, infectious and respiratory diseases, injuries, endocrine disorders and others-declined yet still constituted over 30% of all deaths. Thus, the overall mortality decline was associated with the decline of causes other than NCDs. Mortality risk sharply increased with age. Men had higher mortality than women from heart disease, cancers and other causes, but not from stroke. Lower household wealth quintile people have higher mortality than higher household wealth quintile people, non-Muslims than Muslims. CONCLUSION: Deaths from stroke, heart disease and cancers were either on the rise or remained unchanged, but other causes declined continuously from 2003 to 2017. Immediate strengthening of the preventive and curative healthcare systems for NCDs management is a burning need.

Trends in women's height and the effect of early childbearing on height retardation: An analysis of the height of Bangladeshi women born between 1974 and 1998.

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 in these areas in recent decades, we hypothesised that the average height of Bangladeshi women has increased. Moreover, because pregnancy at an early age affects women's health and nutrition, we hypothesised that women who began childbearing early would experience growth retardation compared to women who had pregnancies at a later age. Methods: We used data from five national surveys conducted between 2004 and 2018 that collected height data from ever-married women aged 15-49 years. We analysed the height of women aged 20-29 years (born between 1974 and 1998) and examined the mean height by birth years, age at first birth (AFB), economic status, religion and region. We conducted multiple linear regression models, controlling for the differential effects of the socio-demographic characteristics on women's height over time and by AFB. Results: The average height of women born between 1974 and 1998 significantly increased by 0.03 cm annually, with fluctuations between 150.3 and 151.6 cm. We also found an association between age at childbearing and height in adulthood - women who began childbearing before age 17 were approximately one centimetre shorter in adulthood than those who began childbearing at a later age. Conclusions: We found evidence of an increasing trend in women's height in Bangladesh and an inhibiting effect of early teenage childbearing on attaining the potential growth of women. The findings call for further studies to investigate early childbearing and its consequences on women's and their children's growth in diverse settings, considering socio-cultural customs influencing early marriage and childbearing.

Role of community-level emergency contraceptive pills awareness and possibilities of long-acting reversible or permanent methods in reducing unwanted births in Bangladesh: evidence from a nationwide cross-sectional survey.

OBJECTIVE: This study aims to investigate the role of community-level emergency contraceptive pill (ECP) awareness in reducing unwanted births (UWBs) in Bangladesh and explore the regional variation in women's appropriateness to adopt long-acting reversible contraceptives or permanent methods (LARCPMs) based on their child desire. DESIGN, SETTINGS AND PARTICIPANTS: We used data from the cross-sectional Bangladesh Demographic and Health Survey 2017-2018. We analysed the planning status of the last live birth 3 years preceding the survey of 20,127 ever-married women of reproductive age. METHODS: Considering women were nested within clusters, a mixed-effect multiple logistic regression was implemented to investigate the association between community-level ECP awareness and UWB by controlling for the effects of contextual, individual, and household characteristics. RESULTS: Only 3.7% of women belonged to communities with high ECP awareness. At the national level, 2% of women had UWB. About 2.1% of women who resided in communities of low ECP awareness had UWB, while UWB was only 0.5% among women residing in high ECP awareness communities. The odds of UWB was 71% lower among women who resided in high ECP awareness communities than among those who resided in communities with low ECP awareness. However, community-level ECP awareness could not avert mistimed birth. Dhaka, Chattogram and Rangpur held the highest share of UWB. Fertility persisted for 89% of the women who wanted no more children. Among women who wanted no more children, 15% were not using any method, 13% used traditional family planning methods and only 13% adopted LARCPM. These women mostly resided in Dhaka, followed by Chattogram and Rajshahi. CONCLUSION: This study highlights the significant positive role of ECP awareness in reducing UWB in Bangladesh. Findings may inform policies aimed at increasing LARCPM adoption, particularly among women residing in Dhaka and Chattogram who want no more children.

Preeclampsia and eclampsia-specific maternal mortality in Bangladesh: Levels, trends, timing, and care-seeking practices.

Background: Despite improvements in many health indicators, maternal mortality has plateaued in Bangladesh. Achieving the global target of reductions in maternal mortality and the associated Sustainable Development Goals will not be possible without actions to prevent deaths due to preeclampsia/eclampsia. Here we examined the levels, trends, specific causes, timing, place, and care-seeking behaviours of women who died due to these two causes. Methods: We used nationally representative Bangladesh Maternal Mortality and Health Care Surveys (BMMSs) conducted in 2001, 2010, and 2016 to examine levels and trends of deaths due to preeclampsia/eclampsia. We based the analysis of specific causes, timing, and place of preeclampsia/eclampsia deaths, and care seeking before the deaths on 41 such deaths captured in the 2016 survey. We also used BMMS 2016 survey verbal autopsy (VA) questionnaire to highlight stories that put faces to the numbers. Results: The preeclampsia/eclampsia-specific mortality ratio decreased from 77 per 100 000 live births in the 2001 BMMS to 40 per 100 000 live births in the 2010 BMMS, yet halted in the 2016 BMMS at 46 per 100 000 live births. Although preeclampsia/eclampsia accounted for around one-fifth of all maternal deaths in the 2010 BMMS, in the 2016 BMMS, the percentage contribution reached the 2001 BMMS level of 24%. An analysis of the VA questionnaire's open section showed that almost all such death cases left their homes to seek care; however, most had to visit more than one facility before they died, indicating an unprepared health system. Conclusions: A cluster of preeclampsia/eclampsia-specific mortality observed during the first trimester, during delivery, and within 48 hours of birth indicates a need for preconception health check-ups and strengthened facility readiness. Awareness of maternal complications, proper care seeking, and healthy reproductive practices, like family planning to space and limit pregnancy through client-supportive counselling, may be beneficial. Improving regular and emergency maternal services readiness is also essential.

Maternal mortality in Bangladesh: Who, when, why, and where? A national survey-based analysis.

Background: Despite a notable decline in recent decades, maternal mortality in Bangladesh remains high. A thorough understanding of causes of maternal deaths is essential for effective policy and programme planning. Here we report the current level and major causes of maternal deaths in Bangladesh, focusing on care-seeking practices, timing, and place of deaths. Methods: We analysed data from the 2016 Bangladesh Maternal Mortality and Health Care Survey (BMMS), conducted with nationally representative sample of 298 284 households. We adapted the World Health Organization's 2014 verbal autopsy (VA) questionnaire. Trained physicians reviewed the responses and assigned the cause of death based on the International Classification of Diseases (ICD-10). We included 175 maternal deaths in our analysis. Results: The maternal mortality ratio was 196 (uncertainty range = 159-234) per 100 000 live births. Thirty-eight per cent of maternal deaths occurred on the day of delivery and 6% on one day post-delivery. Nineteen per cent of the maternal deaths occurred at home, another 19% in-transit, almost half (49%) in a public facility, and 13% in a private hospital. Haemorrhage contributed to 31% and eclampsia to 23% of the maternal deaths. Twenty-one per cent of the maternal deaths occurred due to indirect causes. Ninety-two per cent sought care before dying, of which 7% sought care from home. Thirty-three per cent of women who died due to maternal causes sought care from three or more different places, indicating they were substantially shuttled between facilities. Eighty per cent of the deceased women who delivered in a public facility also died in a public facility. Conclusions: Two major causes accounted for around half of all maternal deaths, and almost half occurred during childbirth and by two days of birth. Interventions to address these two causes should be prioritised to improve the provision and experience of care during childbirth. Significant investments are required for facilitating emergency transportation and ensuring accountability in the overall referral practices.

What shapes attitudes on gender roles among adolescents in Bangladesh.

Background: In Bangladesh, large gender differentials exist in outcomes in almost all spheres of life, stemming from conservative norms and attitudes around gender. Adolescence is a crucial period for social-emotional learning that can shape gender norms and attitudes. Objective: The aim of the paper is to investigate the extent to which adolescents hold egalitarian attitudes toward gender roles, and to examine the factors that influence egalitarian gender attitudes. Methods: The paper uses data from a nationally representative sample survey of 7,800 unmarried girls and 5,523 unmarried boys ages 15-19 years. Adolescents were considered to have egalitarian attitudes on gender role if they disagreed with all the following four unequal gender role statements with regards to socio-economic participation, while respondents who agreed with any one of the four statements were considered to have non-egalitarian attitudes: (1) It is important that sons have more education than daughters, (2) Outdoor games are only for boys, not girls, (3) Household chores are for women only, not for men, even if the woman works outside the home, and (4) Women should not be allowed to work outside the home. Multivariable linear probability regression analysis was implemented to identify the factors shaping attitudes on gender roles. Results: Unmarried girls and boys differ hugely in their views on gender roles regarding socio economic participation-girls were much more egalitarian than boys (58 vs. 19%). The multivariate linear probability model results show girls and boys who completed at least grade 10 were 31% points and 15% points more likely to have egalitarian views on gender roles respectively, compared to girls and boys with primary or less education. Having strong connection with parents is associated with having egalitarian views on gender roles among girls but not boys. Adolescents' individual attitude on gender role is highly associated with the views of their community peers for both girls and boys. Girls and boys who had participated in adolescent programs were 6-7% points more likely to have egalitarian attitude than those who were not exposed to these programs. Egalitarian views were also significantly higher, by 5% points among girls and 6% points among boys, who were members of social organizations compared to those who were not. Watching television had positive influence on egalitarian attitudes among girls but not among boys. To create a more egalitarian society, both men and women need to hold progressive attitudes toward gender roles. The interventions must be multilevel, influencing adolescents at the personal, interpersonal, communal, and societal levels.

Haemorrhage-related maternal mortality in Bangladesh: Levels, trends, time of death, and care-seeking practices based on nationally representative population-based surveys.

Background: Haemorrhage is a major cause of maternal deaths globally, most of which are preventable and predominantly happen in low and middle-income countries, including Bangladesh. We examine the current levels, trends, time of death, and care-seeking practices for haemorrhage-related maternal deaths in Bangladesh. Methods: We conducted a secondary analysis with data from the nationally representative 2001, 2010, and 2016 Bangladesh Maternal Mortality Surveys (BMMS). The cause of death information was collected through verbal autopsy (VA) interviews using a country-adapted version of the standard World Health Organization VA questionnaire. Trained physicians reviewed the VA questionnaire and assigned the cause of death using the International Classification of Diseases (ICD) codes. Results: Haemorrhage accounted for 31% (95% confidence interval (CI) = 24-38) of all maternal deaths in 2016 BMMS, which was 31% (95% CI = 25-41) in 2010 BMMS and 29% (95% CI = 23-36) in 2001 BMMS. The haemorrhage-specific mortality rate remained unchanged between 2010 BMMS (60 per 100 000 live births, uncertainty range (UR) = 37-82) and 2016 BMMS (53 per 100 000 live births, UR = 36-71). Around 70% of haemorrhage-related maternal deaths took place within 24 hours of delivery. Of those who died, 24% did not seek health care outside the home and 15% sought care from more than three places. Approximately two-thirds of the mothers who died due to haemorrhage gave birth at home. Conclusions: Postpartum haemorrhage remains the primary cause of maternal mortality in Bangladesh. To reduce these preventable deaths, the Government of Bangladesh and stakeholders should take steps to ensure community awareness about care-seeking during delivery.

Levels, trends, causes, place and time of, care-seeking for, and barriers in preventing indirect maternal deaths in Bangladesh: An analysis of national-level household surveys.

Background: Eclampsia, haemorrhage, and other direct causes are the primary burden of maternal mortality in Bangladesh, often reducing attention given to indirect maternal deaths (IMDs). However, Sustainable Development Goals may not be achieved without actions to prevent IMDs. We examined the levels, trends, specific causes, timing, place, and care-seeking, and explored the barriers to IMD prevention. Methods: We used three nationally representative surveys conducted in 2001, 2010, and 2016 to examine levels and trends in IMDs. The analysis of specific causes, timing, and place of IMDs, and care-seeking before the deaths was based on 37 IMDs captured in the 2016 survey. Finally, we used thematic content analysis of the open history from the 2016 survey verbal autopsy (VA) questionnaire to explore barriers to IMD prevention. Results: After increasing from 51 deaths per 100 000 live births in 2001 to 71 in 2010, the indirect maternal mortality ratio (IMMR) dropped to 38 deaths per 100 000 live births in 2016. In 2016, the indirect causes shared one-fifth of the maternal deaths in Bangladesh. Stroke, cancer, heart disease, and asthma accounted for 80% of the IMDs. IMDs were concentrated in the first trimester of pregnancy (27%) and day 8-42 after delivery (32%). Public health facilities were the main places for care-seeking (48%) and death (49%). Thirty-four (92%) women who died from IMDs sought care from a health facility at least once during their terminal illness. However, most women experienced at least one of the "three delays" of health care. Other barriers were financial insolvency, care-seeking from unqualified providers, lack of health counselling, and the tendency of health facilities to avoid responsibilities. Conclusions: IMMR remained unchanged at a high level during the last two decades. The high concentration of IMDs in pregnancy and the large share due to chronic health conditions indicate the need for preconception health check-ups. Awareness of maternal complications, proper care-seeking, and healthy reproductive practices may benefit. Improving regular and emergency maternal service readiness is essential.

Factors that provide protection against intimate partner physical violence among married adolescents in Bangladesh.

Background: Intimate partner violence (IPV), and especially intimate partner physical violence (IPPV), perpetrated by husbands, and within adolescence marriage are pervasive in Bangladesh. Younger women are more vulnerable to IPPV. Objectives: We examined factors associated with IPPV experienced by married adolescents ages 15-19 and tested four hypotheses: (1) adolescent girls married to relatively older husbands, (2) adolescents living in extended families with parents or parents-in-law, (3) adolescents who are minimally controlled by husbands, and (4) adolescents who have a child after marriage are protective of IPPV. Methods: We analyzed IPPV data from 1,846 married girls ages 15-19 obtained from a national adolescent survey conducted in 2019-20. IPPV is defined as the respondent having physical violence perpetrated by her husband at least once in the last 12 months. We implemented logistic regression models to test our hypotheses. Results: Sixteen percent of married adolescent girls experienced IPPV. Girls living with parents-in-law or parents had adjusted odds ratio (AOR) of 0.56 (p < 0.001) of IPPV compared to those girls who lived with husband alone. Girls with husbands ages 21-25 years and 26 years or older had AORs of 0.45 (p < 0.001) and 0.33 (p < 0.001) of IPPV compared to those girls with their husband ages 20 and younger. Married adolescent girls who did not own a mobile phone (an indicator of spousal power dynamics) had an AOR of 1.39 (p < 0.05) compared to those girls who had a phone. IPPV risk increases with an increased duration of marriage for those with no living children (p < 0.001) but not for those with at least one living child; the risk was higher among those who had a child within the 1st year of marriage than those who had not yet had a child. At a duration of 4 years and longer, IPPV risk was higher among those with no living children than those with children. Discussion: Findings related to those living with parents-in-law or parents, girls married to relatively older boys/men, having the ability to communicate with outside world, and having a child are protective of IPPV in Bangladesh are new, to our knowledge. Strictly adhering to the law that requires men waiting until the age of 21 to marry can reduce married girls' risk of IPPV. Raising girls' legal marriage age can minimize adolescents' IPPV and other health risks associated with adolescent childbearing.

Religious disparities in health in Bangladesh-the case of hypertension and diabetes: evidence from two nationally representative cross-sectional surveys.

OBJECTIVES: Religious affiliation, beliefs, and practices shape lifestyles and disease risks. This study examined Hindu-Muslim differences in the prevalence and management of hypertension and diabetes in Bangladesh, a religiously plural country with 91% Muslims and 8% Hindus. DESIGN, SETTINGS AND PARTICIPANTS: We used the nationally representative 2011 Bangladesh Demographic and Health Survey (BDHS) and 2017-2018 BDHS data. The 2011 BDHS collected blood pressure (BP) data with an 89% response rate (RR) and fasting blood glucose (FBG) data (RR 85%) from household members aged 35 years and above. The 2017-2018 BDHS collected BP and FBG data from household members aged 18 years and above with 89% and 84% RRs, respectively. We analysed 6628 participants for hypertension and 6370 participants for diabetes from the 2011 BDHS, 11 449 for hypertension and 10 744 for diabetes from the 2017-2018 BDHS. METHODS: We followed the WHO guidelines to define hypertension and diabetes. We used descriptive statistics and multiple logistic regression to examine the Hindu-Muslim differences in hypertension and diabetes, and estimated predicted probabilities to examine the changes in hypertension and diabetes risk over time. RESULTS: Nine in 10 of the sample were Muslims. About 31% of Hindus and 24% of Muslims were hypertensive; 10% of both Hindus and Muslims were diabetic in 2017-2018. The odds of being hypertensive were 45% higher among Hindus than Muslims (adjusted OR: 1.45; 95% CI: 1.23 to 1.71; p<0.001). The levels of awareness, medication and control of hypertension were similar between the religious groups. Between the 2011 and 2017-2018 BDHS, the Hindu-Muslim difference in the prevalence of hypertension increased non-significantly, by 3 percentage points. CONCLUSIONS: Further studies on religious-based lifestyles, Hindu-Muslim differences in diet, physical activity, stress, and other risk factors of hypertension and diabetes are needed to understand Hindus' higher likelihood of being hypertensive, in contrast, not diabetic compared with Muslims.

Socioeconomic disparities in diabetes prevalence and management among the adult population in Bangladesh.

BACKGROUND: Diabetes, one of the major metabolic disorders, is rising in Bangladesh. Studies indicate there is inequality in prevalence and care-seeking behavior, which requires further exploration to understand the socioeconomic disparities in the pathophysiology of diabetes. This study examined the latest nationally representative estimates of diabetes prevalence, awareness, and management among adults aged 18 years and above in Bangladesh and its association with socioeconomic status in 2017-18. METHODS: We used the 2017-18 Bangladesh Demographic and Health Survey data. Diabetic status of 12,092 adults aged 18 years and above was measured in the survey using fasting plasma glucose levels. We applied multivariate logistic regressions to examine the role of socioeconomic status on diabetes prevalence, awareness, and management, after controlling for relevant covariates. RESULTS: Overall, 10% of adults had diabetes in Bangladesh in 2017-18, with the highest prevalence of 16% in the age group 55-64 years. Our analyses found statistically significant disparities by socioeconomic status in the prevalence of diabetes as well as the person's awareness of his/her diabetic condition. However, the effect of socioeconomic status on receiving anti-diabetic medication only approached significance (p = 0.07), and we found no significant association between socioeconomic status and control of diabetes. CONCLUSIONS: We expect to see an 'accumulation' of the number of people with diabetes to continue in the coming years. The rising prevalence of diabetes is only the tip of an iceberg; a large number of people with uncontrolled diabetes and a lack of awareness of their condition will lead to increased morbidity and mortality, and that could be the real threat. Immediate measures to increase screening coverage and exploration of poor control of diabetes are required to mitigate the situation.

Sex differences in the care of the fetus in the mother's womb and the neonate on her lap: Evidence from demographic surveillance and survey data from Bangladesh.

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 Mortality and Health Care Survey (BMMS) 2016. The HDSS follows a well-defined rural population (0.24 million in 2018) to register vital events and migrations and records the use of maternity services for the index birth and medical care-seeking during the terminal illness of each death in verbal autopsy. The BMMS 2016 recorded maternity care and maternal complications for the last live birth of mothers in the same population (weighted n = 27,133; unweighted n = 26,939). Bivariate analyses estimated the use (in %) of maternity services for the index live births and medical services for terminally ill neonates for each socio-demographic variable. Logistic regression models estimated odds ratios (AORs) adjusted for socio-demographic variables and clustering of births to the same mothers. The HDSS registered 49,827 live births and 1,049 neonatal deaths during 2009-2018. We found similar prenatal care-seeking for male and female fetuses but higher facility delivery (AOR = 1.17, 95% CI: 1.12-1.23) and C-sections (AOR = 1.20, 95% CI: 1.15-1.25) for male fetus pregnancies, differences that remain after adjusting for maternal complications. Sex differences persisted in seeking care for terminally ill neonates. Trained provider consultation (AOR = 1.46, CI: 1.00-2.12); hospital admissions (AOR = 1.43, CI: 1.01-2.03); and dying in hospital (AOR = 1.91, CI: 1.31-2.78) were all higher for male neonates. Other variables positively associated with delivery care and medical care-seeking were lower birth order of the child, higher maternal education, and higher household wealth status. Policy and decision-makers need to be aware of gender disparities in maternity care and care of sick neonates and plan remedial actions.

Rural-urban differentials in the influences of individual and geospatial preparedness on institutional childbirth: a cross-sectional study in Bangladesh.

OBJECTIVE: This study aims to explore the rural-urban differentials in the influences of individual and geospatial preparedness on institutional childbirth in Bangladesh. A related aim of this paper is to derive estimates to measure geospatial preparedness for institutional births, through statistical modelling, when no data are available for measuring this areal indicator. DESIGN, SETTINGS AND PARTICIPANTS: The paper used data from a large-scale nationally representative Bangladesh Multiple Indicator Cluster Survey 2019. The analytical sample included 9203 currently married women of reproductive age who had a live birth in the 2 years preceding the survey. METHODS: Mixed effect logistic regression models were employed to explore the rural-urban differentials in influences of individual and geospatial preparedness on institutional childbirth. The district-level random effect estimation was done to measure geospatial preparedness. The conditional autoregressive model was used to examine the association of geospatial preparedness with areal variation in institutional births. RESULTS: In rural settings, women who gave birth to a female newborn were 18% less likely to have facility births compared with women who gave birth to a male newborn. Also, women from households in the highest wealth quintile were twice as likely to have facility births compared with those from households in the poorest wealth quintile. In contrast, in urban areas, facility births did not vary by sex of the fetus or by households' socioeconomic status. The geospatial preparedness explained 8% and 9% of the variability in institutional births in rural and urban areas, respectively. Geospatial mapping revealed low preparedness in the hill tracts. Findings identified geospatial preparedness as a potential source of areal variation in facility births. CONCLUSION: Findings suggest improving district-level preparedness and developing differential programme strategies for urban and rural areas to increase the national prevalence and more equitable use of institutional childbirth in Bangladesh.

Adult death registration in Matlab, rural Bangladesh: completeness, correlates, and obstacles.

Civil registration of vital events such as deaths and births is a key part of the process of securing rights and benefits for individuals worldwide. It also enables the production of vital statistics for local planning of social services. In many low- and lower-middle-income countries, however, civil registration and vital statistics (CRVS) systems do not adequately register significant numbers of births and, especially, deaths. In this study, we aim to estimate the completeness of adult death registration (for age 15 and older) in the Matlab health and demographic surveillance system (HDSS) area in Bangladesh and to identify reasons for (not) registering deaths in the national CRVS system. We conducted a sample survey of 2538 households and recorded 571 adult deaths that had occurred in the 3 years preceding the survey. Only 17% of these deaths were registered in the national CRVS system, with large gender differences in registration rates (male = 26% vs. female = 5%). Respondents who reported that a recent death in the household was registered indicated that the primary reasons for registration were to secure an inheritance and to access social services. The main reasons cited for not registering a death were lack of knowledge about CRVS and not perceiving the benefits of death registration. Information campaigns to raise awareness of death registration, as well as stronger incentives to register deaths, may be needed to improve the completeness of death registration in Bangladesh.

Demographic, socioeconomic, and biological correlates of hypertension in an adult population: evidence from the Bangladesh demographic and health survey 2017-18.

BACKGROUND: Bangladesh is well advanced in the epidemiologic transition from communicable to noncommunicable diseases, which now account for two out of three deaths annually. This paper examines the latest nationally representative hypertension prevalence estimates, awareness, treatment, and control-to identify their association with potential correlates. METHODS: The analyses are based on the recent Bangladesh Demographic and Health Survey 2017-18 data. Univariate analyses and bivariate analyses between the outcome variables and individual covariates were carried out. Then chi-square tests were done to see the proportional differences between them. To examine the demographic, socioeconomic and biological factors affecting hypertension, awareness, treatment and control, we used multivariate logistic regression models. RESULTS: We found that prevalence of hypertension for females and males together aged 35 or more has risen by half between 2011 (25.7%) to 2017 (39.4%). With the broader age range used in 2017, the prevalence is now 27.5% in the population aged 18 years or more. The factors associated with hypertension included older age, being female, urban residence, higher wealth status, minimal education, higher body mass index and high blood glucose level. Following multivariate analyses, many of these characteristics were no longer significant, leaving only age, being female, nutritional status and elevated blood glucose level as important determinants. Over half (58%) of females and males who were found to be hypertensive were not aware they had the condition. Only one in eight (13%) had the condition under control. CONCLUSION: In the coming years, a rising trend in hypertension in Bangladeshi adults is expected due to demographic transition towards older age groups and increase in overweight and obesity among the population of Bangladesh. With more women being hypertensive than men, a targeted approach catering to high risk groups should be thoroughly implemented following the Multisectoral NCD Action Plan 2018-2025. Acting in close collaboration with other ministries/relevant sectors to bring an enabling environment for the citizens to adopt healthy lifestyle choices is a prerequisite for adequate prevention. While screening the adult population is essential, the public sector cannot possibly manage the ever-expanding numbers of hypertensives. The private sector and NGOs need to be drawn into the program to assist.

Stillbirth outcome capture and classification in population-based surveys: EN-INDEPTH study.

BACKGROUND: Household surveys remain important sources of stillbirth data, but omission and misclassification are common. Classifying adverse pregnancy outcomes as stillbirths requires accurate reporting of vital status at birth and gestational age or birthweight for every pregnancy. Further categorisation, e.g. by sex, or timing (intrapartum/antepartum) improves data to understand and prevent stillbirth. METHODS: We undertook a cross-sectional population-based survey of women of reproductive age in five health and demographic surveillance system sites in Bangladesh, Ethiopia, Ghana, Guinea-Bissau and Uganda (2017-2018). All women answered a full birth history with pregnancy loss questions (FBH+) or a full pregnancy history (FPH). A sub-sample across both groups were asked additional stillbirth questions. Questions were evaluated using descriptive measures. Using an interpretative paradigm and phenomenology methodology, focus group discussions with women exploring barriers to reporting birthweight for stillbirths were conducted. Thematic analysis was guided by an a priori codebook. RESULTS: Overall 69,176 women reported 98,483 livebirths (FBH+) and 102,873 pregnancies (FPH). Additional questions were asked for 1453 stillbirths, 1528 neonatal deaths and 12,620 surviving children born in the 5 years prior to the survey. Completeness was high (> 99%) for existing FBH+/FPH questions on signs of life at birth and gestational age (months). Discordant responses in signs of life at birth between different questions were common; nearly one-quarter classified as stillbirths on FBH+/FPH were reported born alive on additional questions. Availability of information on gestational age (weeks) (58.1%) and birthweight (13.2%) was low amongst stillbirths, and heaping was common. Most women (93.9%) were able to report the sex of their stillborn baby. Response completeness for stillbirth timing (18.3-95.1%) and estimated proportion intrapartum (15.6-90.0%) varied by question and site. Congenital malformations were reported in 3.1% stillbirths. Perceived value in weighing a stillborn baby varied and barriers to weighing at birth a nd knowing birthweight were common. CONCLUSIONS: Improving stillbirth data in surveys will require investment in improving the measurement of vital status, gestational age and birthweight by healthcare providers, communication of these with women, and overcoming reporting barriers. Given the large burden and effect on families, improved data must be made available to end preventable stillbirths.

Paradata analyses to inform population-based survey capture of pregnancy outcomes: EN-INDEPTH study.

BACKGROUND: Paradata are (timestamped) records tracking the process of (electronic) data collection. We analysed paradata from a large household survey of questions capturing pregnancy outcomes to assess performance (timing and correction processes). We examined how paradata can be used to inform and improve questionnaire design and survey implementation in nationally representative household surveys, the major source for maternal and newborn health data worldwide. METHODS: The EN-INDEPTH cross-sectional population-based survey of women of reproductive age in five Health and Demographic Surveillance System sites (in Bangladesh, Guinea-Bissau, Ethiopia, Ghana, and Uganda) randomly compared two modules to capture pregnancy outcomes: full pregnancy history (FPH) and the standard DHS-7 full birth history (FBH+). We used paradata related to answers recorded on tablets using the Survey Solutions platform. We evaluated the difference in paradata entries between the two reproductive modules and assessed which question characteristics (type, nature, structure) affect answer correction rates, using regression analyses. We also proposed and tested a new classification of answer correction types. RESULTS: We analysed 3.6 million timestamped entries from 65,768 interviews. 83.7% of all interviews had at least one corrected answer to a question. Of 3.3 million analysed questions, 7.5% had at least one correction. Among corrected questions, the median number of corrections was one, regardless of question characteristics. We classified answer corrections into eight types (no correction, impulsive, flat (simple), zigzag, flat zigzag, missing after correction, missing after flat (zigzag) correction, missing/incomplete). 84.6% of all corrections were judged not to be problematic with a flat (simple) mistake correction. Question characteristics were important predictors of probability to make answer corrections, even after adjusting for respondent's characteristics and location, with interviewer clustering accounted as a fixed effect. Answer correction patterns and types were similar between FPH and FBH+, as well as the overall response duration. Avoiding corrections has the potential to reduce interview duration and reproductive module completion by 0.4 min. CONCLUSIONS: The use of questionnaire paradata has the potential to improve measurement and the resultant quality of electronic data. Identifying sections or specific questions with multiple corrections sheds light on typically hidden challenges in the survey's content, process, and administration, allowing for earlier real-time intervention (e.g.,, questionnaire content revision or additional staff training). Given the size and complexity of paradata, additional time, data management, and programming skills are required to realise its potential.

Electronic data collection in a multi-site population-based survey: EN-INDEPTH study.

BACKGROUND: Electronic data collection is increasingly used for household surveys, but factors influencing design and implementation have not been widely studied. The Every Newborn-INDEPTH (EN-INDEPTH) study was a multi-site survey using electronic data collection in five INDEPTH health and demographic surveillance system sites. METHODS: We described experiences and learning involved in the design and implementation of the EN-INDEPTH survey, and undertook six focus group discussions with field and research team to explore their experiences. Thematic analyses were conducted in NVivo12 using an iterative process guided by a priori themes. RESULTS: Five steps of the process of selecting, adapting and implementing electronic data collection in the EN-INDEPTH study are described. Firstly, we reviewed possible electronic data collection platforms, and selected the World Bank's Survey Solutions® as the most suited for the EN-INDEPTH study. Secondly, the survey questionnaire was coded and translated into local languages, and further context-specific adaptations were made. Thirdly, data collectors were selected and trained using standardised manual. Training varied between 4.5 and 10 days. Fourthly, instruments were piloted in the field and the questionnaires finalised. During data collection, data collectors appreciated the built-in skip patterns and error messages. Internet connection unreliability was a challenge, especially for data synchronisation. For the fifth and final step, data management and analyses, it was considered that data quality was higher and less time was spent on data cleaning. The possibility to use paradata to analyse survey timing and corrections was valued. Synchronisation and data transfer should be given special consideration. CONCLUSION: We synthesised experiences using electronic data collection in a multi-site household survey, including perceived advantages and challenges. Our recommendations for others considering electronic data collection include ensuring adaptations of tools to local context, piloting/refining the questionnaire in one site first, buying power banks to mitigate against power interruption and paying attention to issues such as GPS tracking and synchronisation, particularly in settings with poor internet connectivity.
