INTRODUCTION
Maternal and child health interventions are the cornerstone of public health efforts worldwide, addressing critical issues that significantly impact the well-being and longevity of mothers and children. These interventions cover a broad spectrum of strategies, policies and programs aimed at improving the health, safety and development of women during pregnancy, childbirth and the postpartum period, and ensuring optimal growth and development for infants, children and adolescents. The importance of maternal and child health cannot be overstated, as healthy mothers and children are the foundation of strong societies and prosperous communities [1]- [4].
Over the past few decades, global attention and resources have been increasingly directed towards improving maternal and child health outcomes. This shift has been catalyzed by international commitments, such as the United Nations (UN) Sustainable Development Goals (SDGs), which include targets aimed at reducing maternal and child mortality and improving overall health and well-being. As a result, there has been substantial growth in research and initiatives aimed at understanding, designing and implementing effective interventions in this domain [5]- [7].
However, despite the progress that has been made, challenges remain. Maternal mortality, newborn mortality, malnutrition, inadequate access to health services, and disparities in health outcomes based on socio-economic and geographic factors continue to be major barriers to achieving optimal maternal and child health. In this context, a comprehensive understanding of the global West Science Interdisciplinary Studies  Vol. 01, No. 08, August 2023: pp. 610-620 611 research landscape around maternal and child health interventions is critical. Such understanding not only provides insight into the progress that has been made but also identifies gaps, informs evidence-based policy decisions, and guides resource allocation for maximum impact [1], [4], [8]- [10].
The rationale behind conducting a bibliometric review of the global research landscape on maternal and child health interventions is multifaceted. First, bibliometric analysis offers a quantitative approach to understanding the state of research in a given field, allowing for the identification of trends, key contributors, influential journals and emerging areas of focus. Second, by assessing patterns of collaboration and authorship, it can reveal networks of researchers and institutions that are driving progress in maternal and child health interventions. Thirdly, bibliometric analysis enables the identification of high-impact research, which can guide researchers, policymakers and practitioners to the important works that have shaped the field. Moreover, a comprehensive bibliometric assessment can help bridge the gap between research and practice.
While valuable research has been generated, its translation into effective interventions and policies can be hampered by knowledge fragmentation and limited access to relevant information. By mapping the research landscape and highlighting the links between different research areas, this study facilitates the exchange of ideas and dissemination of knowledge, thereby encouraging interdisciplinary collaboration and the development of evidence-based interventions.

Maternal Health Interventions
Interventions in maternal health include methods for enhancing women's health and wellbeing before, during, and after childbirth. By addressing preventable causes of maternal morbidity, these programs aim to lower maternal mortality, increase access to expert care during childbirth, and enhance maternal health. In order to lower the rates of maternal mortality in both industrialized and developing nations, prenatal care, competent birth attendance, and postpartum care are crucial [11], [12].
Accessibility issues for maternal health services have also been the subject of research, particularly for vulnerable groups. Barriers to timely and effective maternal care have been recognized as socioeconomic circumstances, cultural attitudes, geographic isolation, and a deficient healthcare infrastructure [13]. To address these issues and enhance maternal health outcomes, innovations like community-based treatments, mobile health devices, and task-shifting methods have been investigated [14], [15].

Child Health Interventions
Child health treatments cover a broad range of tactics designed to enhance the health and wellbeing of newborns, kids, and teenagers. Immunization, nutrition, growth monitoring, early childhood development, and the prevention and treatment of pediatric ailments are important areas of focus. By preventing diseases that can be prevented by vaccination, immunization programs, for example, have been instrumental in lowering child mortality [1], [16]- [18].
The twin burden of malnutrition-undernutrition and overweight/obesity-that children in a variety of settings bear has attracted significant attention to nutrition interventions [14]. In order to combat malnutrition and support healthy growth and development throughout the crucial earl

Intersection of Maternal and Child Health Interventions
A major subject in the literature is how maternal and child health are interdependent. Infant and child health outcomes are directly influenced by maternal health during pregnancy and the postpartum period. For example, maternal malnutrition is linked to low birth weight and a higher risk of childhood stunting. The growth and wellbeing of children can also be impacted by mother mental health, including postpartum depression [4], [8], [19], [20].
The outcomes of interventions that concurrently address the health needs of mothers and children have showed promise. Antenatal care, immunization, growth monitoring, family planning, and nutrition education are all part of the complete services offered by integrated healthcare delivery models, such as maternity and child health clinics [8]. These models emphasize the value of a comprehensive approach and acknowledge the inextricable connection between maternal and child health.

METHODS
A research methodology was used to conduct a comprehensive bibliometric assessment of the global research landscape on maternal and child health interventions. The methodology included data collection, data preprocessing, and bibliometric analysis using VOSviewer, a powerful tool for visualizing and analyzing bibliometric data [21].
