Introduction
Childhood stunting, a stark indicator of chronic undernutrition, remains a formidable global health challenge, reflecting deep-seated issues of poverty, inadequate food security, and suboptimal maternal and child health care.The prevalence of stunting exhibits profound variability across different countries, painting a complex mosaic of nutritional well-being that is influenced by a multitude of factors ranging from socio-economic conditions to public health policies.This variability is not just confined to different countries but is also evident within countries, often delineated by urban-rural divides, socio-economic strata, and regional disparities.Studies have demonstrated that while some regions show a promising decline in stunting rates, others are witnessing stagnation or even worsening conditions, indicating uneven progress in tackling this public health issue [1], [2].
The trends in stunting are indicative of broader global health dynamics and are influenced by an interplay of multiple determinants, including maternal health, nutritional practices, sanitation, and socio-economic factors.Despite global initiatives and improved health indicators in many regions, stunting continues to be a persistent issue, Persistent Global Burden of Stunting Among Children Soliman et al.
highlighting the need for targeted interventions.Effective strategies require a nuanced understanding of the local and regional determinants of stunting, with a focus on the critical 1,000-day window from pregnancy to a child's second birthday, a period crucial for preventing stunting [3], [4].
Considering the varying trends and the multifactorial nature of stunting, there is an urgent call for a reinforced global commitment to child nutrition that not only addresses immediate nutritional needs but also tackles the underlying determinants of stunting.This includes strengthening maternal and child health services, enhancing nutritional education, improving sanitation and hygiene, and ensuring food security to build resilient communities capable of sustaining long-term improvements in child growth and development.References [5], [6] The fight against stunting is not only a nutritional challenge but a societal imperative that reflects our collective responsibility towards the world's most vulnerable populations-our children.

Data Collection
The comprehensive table on the prevalence and trend of childhood stunting worldwide was compiled through a meticulous data collection process.This process involved an extensive review of the existing literature, focusing on epidemiological studies, meta-analyses, systematic reviews, and global health reports that provided data on the prevalence of stunting in children across various countries and regions.The studies selected were those that reported specific percentages of stunting prevalence, offered insights into the trends over time, or provided comparative data across different demographics, geographical locations, and socio-economic conditions.

Data Analysis
The data analysis involved synthesizing the findings from the selected studies to extract relevant information on the prevalence and trends of childhood stunting.The key steps included: 1. Data Extraction: Relevant data on the prevalence of stunting, the year of the study, key findings, and demographic details were meticulously extracted from each study.

Trend Analysis:
Where available, data were analyzed to identify trends in stunting prevalence over time, noting any significant increases, decreases, or stable patterns across different regions or globally.

Comparative Analysis:
The data were compared across different geographical regions, time periods, and demographic groups to identify patterns, disparities, and significant findings related to the global state of childhood stunting.4. Synthesis: The extracted data were synthesized into a coherent table format, summarizing the key findings, and presenting a global overview of childhood stunting prevalence and trends, ensuring a comprehensive representation of the available data.
The table serves as a consolidated resource, providing a global snapshot of childhood stunting, which is instrumental for policymakers, researchers, and public health professionals in understanding the scale of the issue, monitoring progress, and strategizing interventions.

Results
Analyzing the key findings about the prevalence and factors associated with stunting in children across various regions and timeframes can be summarized: (  A significant global burden of concurrent stunting in children aged 6-59 months, with higher rates observed in boys and fragile states, indicates a need for targeted interventions in these populations [1]. The Middle East and North Africa (MENA) region reported a high stunting prevalence, particularly in rural areas, low-income countries, and conflict-affected regions, suggesting the impact of socioeconomic and environmental factors on child growth [7].
There was a decreasing global trend in stunting among preschool children over two decades, yet stunting remains a significant concern, especially in Asia and Africa, pointing towards ongoing nutritional challenges [8].
High stunting rates in specific regions like northwest Ethiopia, Congo, and South Africa, indicated regional disparities in child nutrition and the influence of local [9], [11].
Notable decreases in stunting prevalence over the years in different regions reflected the positive impact of nutritional and health interventions, although the rates still vary widely [10], [12].
The association between low birth weight and increased risk of stunting in Indonesian children emphasized the importance of maternal and child health in preventing stunting [14].
Stunting prevalence varied with age, household wealth, and geography in a large cross-country analysis, highlighting the complexity of stunting and the necessity for multifaceted approaches to address it [19].
The pooled prevalence from recent studies indicates a significant proportion of children under five are stunted, particularly in Asia and Some African countries (Ethiopia, Congo) underscoring the persistent public health challenge stunting poses [6].These findings collectively highlighted the ongoing challenge of stunting in children worldwide, influenced by a mix of demographic, socioeconomic, and environmental factors, and underscored the critical need for targeted and effective nutritional and health interventions.

Discussion
The different findings presented in the result section reflect a significant variation in the prevalence of stunting across different countries, as well as varying trends in some countries showing either improvement or deterioration.These variations can be attributed to a multitude of factors ranging from socioeconomic status, public health policies, and maternal and child health services, to nutritional practices and environmental conditions.

Variation in Prevalence Among Countries
The stark differences in stunting prevalence rates across countries, as illustrated by the data, can be influenced by several key factors: Socioeconomic Factors: The prevalence rates are notably higher in low-income countries (some African and South Asian countries) and regions experiencing conflict, such as in the Middle East and North Africa, and in rural areas compared to urban ones [7].Economic instability, poverty, and food insecurity are closely linked to malnutrition and stunting, as they limit access to nutritious food, healthcare, and sanitation [1].
Maternal and Child Health Services: Access to and the quality of maternal and child health services play a crucial role.For instance, low birth weight, which is a risk factor for stunting, is associated with poor maternal nutrition and inadequate prenatal care [14].Countries with better healthcare systems tend to have lower stunting rates due to effective nutritional interventions and education [12].
Nutritional Practices: Dietary diversity, breastfeeding practices, and the availability of micronutrient-rich foods significantly affect stunting rates.In regions where there is less emphasis on these practices, or where food security is a major issue, higher rates of stunting are observed [10].
Public Health Policies and Interventions: The implementation of effective public health policies and interventions, including nutrition programs, education, and social safety nets, can lead to significant reductions in stunting, as seen in countries like Brazil, where a sharp decline in stunting was observed over 33 years [12]. 4.2.Trends in Prevalence: Improvement Versus Deterioration Improvement: The global decrease in stunting rates from 1990 to 2010 signifies the impact of concerted public health efforts, improved socioeconomic conditions, and better maternal and child health services [8].Countries that have shown a commitment to addressing malnutrition through comprehensive strategies, including fortification, supplementation, and education, tend to exhibit a downward trend in stunting prevalence.

Persistent Global Burden of Stunting Among Children
Deterioration: Conversely, the increase in stunting in certain cohorts, as observed in some studies, could be attributed to deteriorating economic conditions, conflict, or inadequate public health strategies.In such contexts, children are more vulnerable to the compounding effects of poverty, poor dietary intake, and limited access to healthcare, which can exacerbate the rates of stunting [15].

Conclusions
The variation in stunting prevalence and the different trends observed across countries highlight the multifactorial nature of malnutrition, influenced by a complex interplay of demographic, socioeconomic, environmental, and policy-related factors.Addressing stunting effectively requires a multidimensional approach, tailored to the specific needs and challenges of each region, emphasizing the importance of sustained and integrated public health efforts to improve nutrition, healthcare access, and overall living conditions.

Recommendations (Fig. 2)
In addressing the critical challenge of global stunting, the following recommendations are proposed to tackle its multifaceted causes and to promote sustainable growth and development in affected populations.

Governments and international organizations
should reinforce public health policies focusing on reducing child malnutrition.This includes integrating stunting reduction strategies into national health development agendas.2. Improving access to and the quality of maternal and child health services is crucial.This includes prenatal care, maternal nutrition, breastfeeding support, and infant and young child feeding (IYCF) programs.

TABLE I :
The Prevalence and Trend of Childhood Stunting Worldwide analysis across 84 countries found a 3.0% prevalence of children aged 6-59 months being concurrently wasted and stunted, with an estimated burden of 5,963,940 children.Higher rates were observed in boys and fragile states.
[15]tha et al.[14]2023 Investigated the correlation between birth weight and stunting, highlighting a significant association where low birth weight increased the risk of stunting in Indonesian children under five.Not specifiedLundeen et al.[15]2014 Prevalence of stunting at 1 year ranged from 21% (Vietnam) to 46% (Ethiopia).From age 1 to 5 years, stunting prevalence decreased by 15•1 percentage points in Ethiopia but increased in the other cohorts by 3% in Vietnam and to 5•3% in India.
3. Tailored interventions that address the specific dietary needs of children at risk of stunting, such as micronutrient supplementation and fortification, should be scaled up. 4. Addressing the underlying socioeconomic factors contributing to stunting, such as poverty, food insecurity, and lack of education, is essential.Social protection programs, income-generating activities, and education can play a significant role in this regard.5. Continuous monitoring, evaluation, and research are necessary to understand the evolving patterns of stunting and to assess the impact of interventions.This will enable the adaptation of strategies to local contexts and emerging challenges.6. Combating stunting requires a coordinated approach involving various sectors such as health, nutrition, education, water, sanitation, and social services.Partnerships between governments, nongovernmental organizations (NGOs), the private sector, and communities are essential to ensure effective and sustainable outcomes.
