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 household economic status. With the exception of the neonatal period, birth spacing effects were highly significant. A preceding birth interval of < 15 months was associated with a greater mortality risk in the post-neonatal period for children with an older sibling who survived infancy. However, a short preceding birth interval did not adversely affect post-neonatal mortality if the older sibling died in infancy. Neonatal and post-neonatal deaths were higher if older siblings had died in respective age intervals. A pregnancy interval of < 12 months after childbirth raised the risk of death at ages 1-2 years considerably if the child was born after a short birth interval (< 15 months). The results suggest that the high mortality risks of closely spaced children are due to sibling competition for parental resources.

Background: The level of perinatal mortality in Bangladesh is one of the highest in the world. Certain childbearing practices and low use of antenatal care make Bangladeshi women vulnerable to adverse birth outcomes. Women in Bangladesh also remain considerably subordinate to men in almost all aspects of their lives, from education and paid work to healthcare utilisation. Lack of these opportunities contributes to the low status of women within family and society, and to generally poor health outcomes for women and their children. Objective: This study investigates the risk factors of perinatal deaths in light of the low level of women's autonomy, and the relative role of childbearing practices and antenatal care in influencing the relationship between autonomy and perinatal deaths. Methods: The relevant data was extracted from the 2014 Bangladesh Demographic and Health Survey. Causal mediation analysis was undertaken to investigate the effects of mediators on the associations between women's autonomy and perinatal deaths. Results: The risk of perinatal deaths was greater by about 44% and 39% respectively for high-risk maternal age and birth interval. Those who had received sufficient antenatal care had a much lower risk of perinatal deaths compared to those who had not received sufficient care. No significant direct relationship between women's autonomy and perinatal deaths was evident. However, the influence of women's autonomy was mediated through maternal age, birth interval and antenatal care, and the average amount of mediation was approximately 9.7%, 25.6% and 9.9% respectively. Conclusions: In Bangladesh, although women's autonomy did not exert any significant direct influence on perinatal deaths, the influence was transmitted through the pathways of childbearing practices and use of antenatal care.

The negative relationship between birth interval length and neonatal mortality risks is well documented, but heterogeneity in this relationship has been largely ignored. Using the Bangladesh Maternal Mortality and Health Care Survey 2010, this study investigates how the effect of birth interval length on neonatal mortality risks varies by maternal age at birth and maternal education. There is significant variation in the effect of interval length on neonatal mortality along these dimensions. Young mothers and those with little education, both of which make up a large share of the Bangladeshi population, can disproportionately benefit from longer intervals. Because these results were obtained from within-family models, they are not due to unobservable heterogeneity between mothers. Targeting women with these characteristics may lead to significant improvements in neonatal mortality rates, but there are significant challenges in reaching them. [ABSTRACT FROM AUTHOR]

Objective: The study examines the relationship between pregnancy spacing and seven measures of maternal morbidity in Matlab, Bangladesh.Method: The study analyzes maternal morbidity data on 11,122 women who visited a health center during their third trimester of pregnancy between 1996 and 2002. Adjusted odds ratios were obtained through logistic regression analysis to assess the effects of pregnancy intervals of differing lengths while holding constant other influences (six variables) on maternal morbidity.Results: After controlling these variables, pre-eclampsia and high blood pressure are significantly more likely for women with preceding inter-pregnancy intervals of less than 6 months or 75 months or more compared to those with intervals of 27-50 months. Premature rupture of membranes is significantly more likely following inter-pregnancy intervals of 6-14 months, and edema is significantly more likely following inter-pregnancy intervals over 50 months.Conclusion: Short and long inter-pregnancy intervals are associated with increased incidence of some maternal morbidities.

This article reports on the results of a study conducted in rural Bangladesh on the influence of maternal weight on the components of birth intervals, including gestation and intrauterine mortality, the duration of postpartum amenorrhea, and the duration of waiting time to conception (the menstrual interval). When biological factors (including maternal age, parity, and supplementation practices) and behavioral variables, including religion, education, and occupation, were controlled, maternal weight was found to be related to the risk of intrauterine mortality and to the probability of resuming menses in the postpartum period. The implications of these findings for policies and programs in developing countries are discussed. [ABSTRACT FROM AUTHOR]

Stunting is the core measure of child health inequalities as it reveals multiple dimensions of child health and development status. The main focus of this study is to show the procedure of selecting the most appropriate logistic regression model for stunting by developing and comparing several plausible models, which ultimately helps to identify the predictors of childhood stunting in Bangladesh. This study utilizes child anthropometric data collected in the 2014 Bangladesh Demographic and Health Survey. Valid height‐for‐age anthropometric indices were available for a total of 6,931 children aged 0–59 months, of which about 36% were stunted. Ordinary logistic, survey logistic, marginal logistic, and random intercept logistic regression models were developed assuming independence, sampling design, cluster effect, and hierarchy of the data. Based on a number of model selection criteria, random intercept logistic model is found the most appropriate for the studied children. A number of child, mother, household, regional, and community‐level variables were included in the model specification. The factors that increased the odds of stunting are children older than 11 months, short birth interval, recent morbidity of children, lower maternal education, young maternity, lower maternal body mass index, poor household wealth, urban residential place, and living in Sylhet division. Findings of this study recommend to utilize an appropriate logistic model considering the issues relevant to the data, particularly sampling design and clustering for determining the risk factors of childhood stunting in Bangladesh.
