Factors affecting under-five child mortality rate in India

Introduction

Information and awareness of child mortality are important factors for determining the demographic pattern of the population and it's also indicating one's country's socioeconomic growth and development. It indexed the quality of life in one's country. As we know children are important assets of any nation. One nation's future and development are dependent on the healthy development and growth of its child population. Every child in this world has a right to a safe birth, proper pre-and post-natal care, survival, mandatory education, vital food, and healthcare that all are necessary for a healthy life. Since early ages are more exposed to fatal death causes. The healthy development of children is crucial to the future well-being of any civilization. Because they are still developing, children are especially vulnerable -more so than adults -to poor living conditions such as poverty, inadequate health care, nutrition, safe water, housing, and environmental pollution. The effects of disease, malnutrition, and poverty threaten the future of children and therefore the future of the societies in which they live. The costs to society of failing its children are huge. It is experienced the children's earliest experiences significantly influence their future development. The information of survival and healthy development of children will help taking appropriate measures and policy decisions in right directions. According to the United Nations World Population prospectus (2022) now there are 1.9 billion children in the world, but they are but 27% of the world population and it is projected that 136 million babies will be born worldwide in 2050. In 2050, the estimate will be still 1.9 billion but comprising 20% population. Children belong to a vulnerable section of the population. Sustaining and encouraging a healthy state of children and preserving sustainable survival is very important. Child mortality is a key indicator of a child 's state of well-being and sustenance but also for the execution of Millennium Development, Goal 4 aim resulted in a 2/3 rd reduction in the under-five mortality rate between 1990 and 2015. With the renewed focus on child survival, tracking of progress in the reduction of child mortality is increasingly important that's why sustainable development goals are set up. As we all have seen in the recent pandemic situations how the threatening drop in mortality could be, it was well cognized that keeping up with sustained growth and protecting even more lives would need the utilization of proper sources and adequate care. This understanding of the survival of children for survival of mankind and improving the quality of their lives led to the inclusion of child survival goals in several global visions including the United Nations Global Strategy for Women's Children's and Adolescents' Health (2016-2030) and the Sustainable Development Goals (SDGs). SDG Target Goal 3.2 calls for ending preventable deaths of new-borns and children under age 5, with all countries aiming to have a neonatal mortality rate of 12 or fewer deaths per 1,000 live births and an under-five mortality rate of 25 or fewer deaths per 1,000 live births by 2030. With a vision to reduce CHILD mortality and reductions in preventable causes of death. Currently, UN IGME estimates child mortality which is critical to the monitoring of progress toward the SDG goal. In recent last 30 years have observed striking reductions in child mortality under-five mortality have dropped by almost 60 per cent since 1990 to 38 deaths per 1,000 live births in 2019-still, the global burden of child deaths remains immense according to UN IGME Report on levels and trends in child mortality (2020). It also states that in 2019 alone, 7.4 (7.2, 7.9) million1 children, adolescents and youth died mostly of preventable or treatable causes. In 2019, globally, 70 per cent of deaths among children global under-five mortality rate fell to 38 (36, 41) deaths per 1,000 live births in 2019 from 93 (92, 95) in 1990 and 76 (75, 77) in 2000 -a 59 (56, 61) per cent and 50 (46, 52) per cent decline, respectively. Occurred among children under 5 years of age, accounting for 5.2 (5.0, 5.6) million deaths. Among underfive deaths, 2.4 million (47 per cent) occurred in the first month of life, 1.5 million (28 per cent) at age 1-11 months, and 1.3 million (25 per cent) at age 1-4 years. (UN IGME) If the child survival SDG targets are to be fulfilled on time, resources and policy must be geared toward not only sustaining current rates of decline but also accelerating progress, which would save millions of lives. Demography and Health Surveys (DHS) are nationally-representative household surveys that provide data for a wide range of monitoring and impact evaluation indicators in the areas of population, health, and nutrition. According to UNICEF in 2021, 5.0 million children under 5 years of age died. The global under-five mortality rate declined by 59 per cent, from 93 deaths per 1,000 live births in 1990 to 38 in 2021. In 2021 alone, roughly 13,800 under-five deaths occurred every day. Under According to the UNIGME Report, India a developing country with most of the world's population experienced half of the most under-five deaths in third with Nigeria although there is a decline in overall under-five child mortality rates from previous times but still among the top 5 counties with most no. of deaths. According to NFHS -5 Survey report, the five previous years before the survey 42 deaths are reported per 1000 live births. These estimates will be helpful to reduce under-five deaths risk and to implement serval measures to improve the quality of life in India.

DHS regularly collects data on infant and child mortality and child health

Objective

The objective is to study and analyse the determinants which factors are affecting under-five child mortality in India by using Multiple Linear Regression and conducting Exploratory Data Analysis (EDA) of under-five mortality rates using NFHS-5 Survey Data. 1. Linearity: Linear relationship between the dependent (Y) and independent variables (X).

Data Sources

Normality:

The residuals are normally distributed.

No multicollinearity:

There is no high relationships among all independent variables. 4. No Heteroscedasticity: The error variance (𝜎𝜎 2 ) is homogeneous (same variance).

Exploratory Data Analysis (EDA)

Which is an approach to analysing data sets to summarize their main characteristics, often with visual methods. Originally developed by American mathematician John Tukey in the 1970's, EDA techniques continue to be a widely used method in the data discovery process today. The main goals of EDA are to:  Summarize the main characteristics of the data  Identify patterns and trends in the data  Check the assumptions of the data  Identify outliers and anomalies  Formulate hypotheses for further analysis

In R programming and Python, there are many libraries that can be used to perform EDA, such as ggplot2, matplotlib, seaborn, and pandas. These libraries provide a wide range of visualization and data manipulation functions that can be used to perform EDA. In conclusion, EDA is an approach to analysing data sets to summarize their main characteristics, identify patterns and trends, and formulate hypotheses for further analysis.

Empirical Investigation

On the basis of correlation Map of India is categorised in colour various components. The dark region in the map of India represents the states of Uttar Pradesh with the highest rate of under-five mortality which is 59.8, followed by Bihar at 56.4 and Chhattisgarh 50.4. The lightest shade in the map was observed in the lowest under-five mortality rate Pondicherry which has 3.9

and Kerala with a value 5.2 which has the least under-five child mortality 5.2. The moderate-colored geographical regions depict the states with moderate rates of under-five child mortality. The above listed chart represents the states which have high under five mortality rate although the vaccination rate is highest but still rate is above 50. The above density curve shows that there is a high chance of U5MR due to Under Weight Child.

The above is the heat map which is representing the correlation matrix between dependent and independent Variables.

Conclusion

In conclusion, child mortality remains a significant public health challenge in India. Despite improvements in access to health care and nutrition, the country still experiences high rates of child mortality due to a combination of factors including poverty, inadequate sanitation, poor maternal health, and a shortage of trained health care workers. Addressing these underlying issues will be crucial in reducing child mortality and improving the health and well-being of children in India. Moreover, implementing effective health education and prevention programs, strengthening the health care system, and addressing the social determinants of health can help to mitigate the impact of child mortality in India. In order to achieve the goal of reducing child mortality, will require a concerted effort from both the government and society as a whole.
