Effect of antenatal care and social well-being on early neonatal mortality in Bangladesh

Reduction of child mortality was one of the major goals of MDGs and its target was to reduce childhood mortality rate up to 66% within the year 2015 [1]. With the target of sustainable development goals (SGD) for achieving universal health coverage, neonatal mortality must decline in tandem with child mortality. Childhood mortality is a very prominent factor in the public health sector of any country (Mustafa and Odimegwu 2008). As a cause of childhood mortality, including early neonatal mortality, different socio-economic factors, socio-demographic factors, nutritional factors of the mothers are involved [2] and other factors may also be responsible [3].

The infant mortality rate was 94/1000 live births and the under-five child mortality was 151/1000 live births in the year 1990 [4]. But just after 6 years both infant mortality rate and under five child mortality rate have declined with IMR at 46/1000 live births and under-5 mortality rate at 58/1000 live births in the year 2015 [5]. According to the Health Bulletin 2017 of DGHS, the neonatal mortality rate is reported as 19 per 1000 live births (SVRS 2016) and 28 per 1000 live births (BDHS 2014) [6]. The neonatal period (first 28 days of life) is the most vulnerable time for a child. But recently the neonatal mortality is decreasing worldwide as well as in Bangladesh, where the neonatal mortality rate has decreased from 36 to 19 deaths per 1000 live births [7]. However, the decreasing rate of neonatal mortality is slower compared to post-neonatal mortality rate. So, more emphasis has to give to improve this state of affairs.

The most significant indicator of child well-being is the under-five child mortality rate including good health and nutritional status of the children across the world [8].

The rate of child mortality is decreasing globally. For example, during the year 1990, the rate of child mortality has declined across all the regions under WHO with the exception of Western Pacific Regions [8]. Despite this decreasing pattern, child survival remains an urgent concern. In spite of the subsequent development of health sectors, still a significant percentage of children (i.e. 17,000/per day) die before reaching their fifth birthday and this rate of childhood mortality is significantly higher in the low income countries compared to high income countries [9]. According to UNICEF, in 2013 the rate of under-five child mortality for low income countries was 76/1000 live births and this rate was approximately twelve times higher than high income countries [10].

Overall it has been found that across the globe the neonatal mortality is decreasing but this rate of decline is slower compared to post neonatal mortality. In the total life span for a human being the first 28 days of life are the most vulnerable time period for his survival. For that reason, more efforts should be made to reduce early neonatal mortality. Bangladesh is not an exception to this trend of childhood mortality. So, by considering all these issues, this paper aims to find out the effect of antenatal care and social well-being on early neonatal mortality in the context of Bangladesh.

In this study, around 17.0% respondents reported that they ever had experience of early neonatal mortality in their reproductive life-span (Fig. 1).

The average age of the study population is 29 years. Women’s school attendance is an important factor to reduce early neonatal mortality. In this study around 72.2% respondents reported that they had ever attended school and the remaining 27.8% stated that they never attended school. In terms of place of residence, only 17.3% respondents came from urban areas and 82.7% from the rural areas. In terms of wealth index of the respondents, 22.7% are poorest, 20.8% are poorer, 20.1% are less poor, 19.6% are richer and the remaining 16.7% comes from the richest family. Among the respondents around 65.2% reported that they received antenatal care during their time of pregnancy and the remaining 34.9% did not. Approximately 59.1% respondents reported that they received TT injection during their pregnancy, whereas 40.9% did not (Table 1).

The early neonatal mortality is influenced by many factors. According to the findings of this study women’s school attendance shows a significant association (p < 0.001) with early neonatal mortality. This study found that the women who ever attended school has lower percentage of early neonatal mortality (11.8%) compared to women who never attended school (26.8%).Women who received antenatal care during their pregnancy has significantly (p < 0.001) lower percentage of early neonatal mortality (ENM) (10.2%) compared to women who never received antenatal care during their pregnancy (15.6%). The study also found significant association (p < 0.001) between receiving TT injection and early neonatal mortality. According to the findings of this study around 10.7% women reported early neonatal mortality although they had received TT injection, in comparison to 14.0% women who had never received TT injection.

In terms of place of residence, women who live in rural areas have significantly higher (p < 0.001) early neonatal mortality (17.2%) compared to the women living in urban areas (13.0%).Wealth index has also statistically significant impact (p < 0.001) on early neonatal mortality (ENM). This study found that ENM is higher in the poorest groups (20.8%) compared to the richest groups (10.1%) (Table 2).

Logistic regression was used to determine the effect of antenatal care and social well-being on ENM. According to the findings of logistic regression model, women who received antenatal care are likely to have 18.0% lower odds of ENM (OR = 0.82, CI = (0.71–0.95)) compared to women who did not and this difference is statistically significant. The odds of experiencing ENM for the respondents who received TT injection during pregnancy is significantly 21.0% lower (OR = 0.79, CI = (0.69–0.91)) compared to unvaccinated respondents. This study found significant impact of school attendance of the women on ENM compared with women who ever attended school having 54.0% lower odds of ENM (OR = 0.46, CI = (0.39–0.53)) compared to women who never attended school. In terms of place of residence, the urban respondents reported that they experienced 20.0% lower odds of ENM (OR = 0.80, CI = (0.64–0.99) compared to rural women. In terms of wealth quintile, woman from the richest families are at 45.0% lower odds of experiencing ENM (OR = 0.55, CI = (0.42–0.72) compared to the poorest, with the difference being statistically significant (Table 3).

Along with other socioeconomic factors, the antenatal period is significantly important for the health of mother and her future offspring. Child survival can be improved by improving care during antenatal period. The present study examined the effects of antenatal care and social well-being on early neonatal mortality (ENM) in Bangladesh. In this study the Bangladesh Multiple Indicator Cluster Survey data was used which was conducted from December 2012 to March 2013 with the collaboration of the Bangladesh Bureau of Statistics (BBS) and Ministry of Planning. The survey used the multistage stratified sampling method for collecting data. This is one of the few studies that focus on the impact of antenatal care and social well-being on early neonatal mortality using a large scale secondary data set.

The results of this study give an overall idea about how proper antenatal care and social well-being can reduce the early neonatal mortality in Bangladesh. The study population of this research was 15–49 years aged group women and among these 51,627 women 44,207 were ever married and had ever given birth. Among these ever married women, 17.0% had history of ENM in their entire reproductive age. To find out the causes of death this study examined several possible factors that could contribute majorly.

The multivariate analysis has been applied to determine the effect of antenatal care and social well-being on early neonatal mortality. Findings from logistic regression model showed that women who received antenatal care, compared to those who did not, experienced 18.0% lower odds of early neonatal mortality; similar findings have been reported by other researchers [11‐17]. In terms of wealth quintile, women from the richest family are likely to have 45.0% lower odds of ENM than their poorest counterparts. This finding is consistent with that of other researchers [12, 17‐19].

Receiving proper vaccination is an important factor to reduce early neonatal mortality. Findings of this study shows that odds of experiencing ENM for the respondents who received TT injection during pregnancy is significantly 21.0% lower compared to unvaccinated respondents. This finding related to immunization is consistent with that of other researcher [4]. Similar to other socio-demographic factors, place of residence also creates an effect in experiencing early neonatal mortality. In terms of place of residence, based on the findings of this study, the urban respondents reported that they experienced 20.0% lower odds of ENM compared to rural women; similar findings have been reported by other researchers [1, 20, 21].

School attendance is also a significant factor affecting the respondents’ risk of experiencing early neonatal mortality. This study found significant impact of school attendance of the women on ENM with women who ever attended school having 54.0% lower odds of ENM compared to women who never attended school; this finding related to educational attainment is consistent with that of other researchers [1, 14, 22]. So, education is an important factor to reduce early neonatal mortality because having proper education will encourage all pregnant mothers to engage in effective health care seeking behavior that will ultimately reduce neonatal deaths.

Findings of this paper suggest that women’s antenatal care, social well-being and TT vaccination have a significant role in lowering ENM. This study recommends that for reducing early neonatal mortality (ENM) we should ensure proper antenatal care during pregnancy. Another issue is that the people who are richest and educated will be able to prevent early neonatal mortality by taking the necessary proper actions. So, socio-economic development is also important to address this issue properly. If all the measures taken sufficiently and with alacrity, it will be possible lower ENM which will impact child mortality favorably.
