CORRELATION BETWEEN LBW HISTORY AND STUNTING INCIDENCE: A LITERATURE REVIEW

Background : Indonesia is facing a significant nutrition problem characterized by a high prevalence of undernutrition cases. Malnutrition is a consequence of poor nutritional status. Stunting is one form of malnutrition associated with a history of inadequate nutrient intake, making it a chronic nutritional problem. One potential factor affecting child growth is a history of low birth weight (LBW). The study aims to analyze the correlation between a history of LBW (Low Birth Weight) and the occurrence of stunting. Method: This research used a literature review study design, using secondary data sourced from electronic databases, consisting of 111 Pubmed articles, 518 Google Scholar articles, and 138 Science Direct articles. Article searches were conducted using keywords related to low birth weight for gestational age, stunting, and children, resulting in 15 relevant articles. The searches using these keywords are limited ( the last 10 years) and then screened according to inclusion and exclusion criteria. Result: Twelve of fifteen pieces of literature reinforce each other by finding low birth weight has a correlation with the occurrence of stunting. While some studies have confirmed a significant correlation between LBW and stunting, other studies have not found any such link. This suggests that the relationship between LBW and stunting is intricate, and there may be other factors that contribute to the occurrence of stunting . Conclusion: A history of LBW (Low Birth Weight) is a contributing factor in the occurrence of stunting in children.


INTRODUCTION
Chronic stunting is a condition in which a child's growth is inhibited, causing them to be shorter than expected for their age.Unfortunately, this problem is prevalent among toddlers around the world, with as many as 22% or around 149.2 million affected in 2020 (World Health Organization, 2021).This indicates that stunting remains a significant concern in global health efforts.
Stunting is a significant issue in Indonesia, with data from the Riset Kesehatan Dasar (2018) showing that about 7 million toddlers, or approximately 30.8%, were stunted.The Indonesian government has set a target of 14% for 2024, but the current figure is far above that (Yuana et al., 2021).From Global Nutrition Report 2016, Indonesia ranks 108th out of 132 countries worldwide in stunting prevalence and is second rank after Cambodia in Southeast Asia (Rocha et al., 2016).Moreover, Indonesia is one of 17 countries grappling with both under and overnutrition (IFPRI, 2014).
Childhood stunting can have severe and lasting effects on health and development.It can impede physical growth, cognitive development, and increase the risk of health issues in adulthood (Kementerian Kesehatan RI, 2018).One of the contributing factors to stunting is low birth weight (LBW), which occurs when a newborn weighs less than 2,500 grams.Babies born with LBW are more likely to experience stunting compared to those born at a normal weight (Ode et al., 2022).
In fact, toddlers who were born with LBW are 5.9 times more likely to suffer from stunting than those born at a normal weight (Lukman et al., 2021).
The meta-analysis conducted by Upadhyay et al. (2019) showed that LBW children had cognitive scores 5 points lower and motor scores 4 points lower compared to children with normal birth weight.Individuals born with low birth weight have a lower risk of cognitive function, thus having higher academic performance, mental disorders, and developmental delays compared to long-term healthy people.This condition is associated with neurodevelopmental deficits, especially in the cerebral white matter, decreased total brain volume, changes in cortical volume and structure, decreased cell number, and deficits in myelination.
Brain connectivity is also impaired as evidenced by a deficit in nerve migration, reduced dendritic processes, and less efficient neural networks (Upadhyay et al., 2019).
There is a much higher developmental delay at the age of 2-3 years among babies born prematurely and/or LBW.Exclusive breastfeeding, timely introduction and adequacy of complementary foods, and access to effective treatment of wasting are necessary for all children, but with special emphasis on infants born preterm and/or LBW to reduce developmental delays that may reduce the prevalence of severe wasting by 61.4%, and can also reduce mortality related to malnutrition (Ahishakiye et al., 2019).
Researchers are conducting a literature review to investigate the connection between low birth weight (LBW) and stunting incidence.This study thoroughly searches literature sources, such as scientific journals, articles, and published research reports.The researchers have selected studies that meet certain inclusion and exclusion criteria and have extracted useful data from each one.

METHODS
This research employs a literature review design, using secondary data from electronic databases such as Pubmed, Google Scholar, and Science Direct.The search was conducted using specific keywords related to LBW, stunting, and children.
This research follows the PRISMA statement, which details the purpose of the review, the author's approach, and the results obtained (Page et al., 2021).
Specifically, this study used the PRISMA 2020 statement.To conduct a literature search, specific inclusion and exclusion criteria were established.The inclusion criteria required studies with observational or experimental designs that contained information on LBW (birth weight less than 2500 grams or equivalent) and stunting (height below age and sex standards) in children aged 0-5 years who met the LBW criteria.The studies had to be published within the last 15 years.The exclusion criteria included articles in systematic reviews, literature reviews, and metaanalyses.

RESULTS AND DISCUSSION
We conducted a literature search across multiple sources during the data selection and analysis process.We found a total of 111 articles from Pubmed, 138 articles from Science Direct, and 519 articles from Google Scholar.Following this, we screened the articles by reviewing their title, abstract, keywords, and content.Following the screening process, 15 articles were deemed relevant to this research.The next step involves interpreting and drawing conclusions from the selected articles.Specifically, researchers examined the relationship between LBW (low birth weight) status and the incidence of stunting in Indonesia using the 15 chosen articles.Table 1 provides a detailed description of the characteristics of these articles.

Researcher
Article Title Research result Lidia Fitri (2017) The The studies conducted have shown varying results regarding the relationship between low birth weight (LBW) and stunting.Some studies have found a correlation between the two, while others have not.According to research by Lidia Fitri et al (2017), 72.7% of 22 LBW toddlers were found to be stunted.
The chi-square analysis yielded a p-value of 0.000 <0.05, indicating a significant correlation between low birth weight and stunting in toddlers at the Lima Puluh Health Center (Fitri, 2018).According to research by Fatimah et al (2020), 71.9% of toddlers who experienced LBW were also stunted, while only 12.5% of LBW toddlers were not stunted.Additionally, 28.1% of toddlers who were stunted did not experience LBW, and 87.5% of toddlers who were not stunted also did not experience LBW (Murti et al., 2020).
According to Afif et al's (2021) research, there was a significant relationship between LBW history and stunting incidence at the Sekupang Health Center in Batam City in 2019, as evidenced by a p-value of 0.000 from the Chi-Square Test Analysis (Alba et al., 2021).According to Nasution's (2014) research, there is a significant relationship between low birth weight (LBW) and stunting in children aged 6-24 months.Children born with LBW have a 5.6 times greater risk of becoming stunted than those born with normal weight (Nasution, Nurdiati and Huriyati, 2014).
According to research by Ade Ira et al ( 2017), children aged 12-60 months born with low birth weight (LBW) have three times the risk of suffering from stunting.The statistical test results showed a p-value of 0.049 with an odds ratio of 3 (0.97-9.3), indicating a significant relationship between LBW and stunting incidence (Zahriany, 2017).
According to Ayuningtyas et al's (2020) research, 199 respondents from Koncang Village, Koroncong Village, and Kadugadung Village in Cipeucang District, Pandeglang Regency, Banten were studied.Of these respondents, 11.1% were underweight children with a history of LBW, 23.6% were underweight and experiencing stunting, 5.0% who experienced stunting had a history of LBW.
The study found a correlation between a history of LBW and the incidence of stunting in toddlers (Ayuningtyas, 2020) According to Rochmah et al's (2017) research, there is a correlation between low birth weight, maternal height, economic status, and stunting in the Wonosari I Health Center's working area.The odds ratios for maternal height, low birth weight, and economic status are 10.1, 5.8, and 4.8, respectively, indicating that these variables are risk factors for stunting.(Rochmah, 2017) According to research by Sutarto (2021), there is a correlation between Low Birth Weight (LBW) and stunting incidence in toddlers (aged 24-59 months) at Way Urang Health Center in South Lampung Regency.Additionally, providing complementary food for six months during the growth period is effective in addressing stunting, in conjunction with improved quality of health examination services (ANC) during pregnancy and childbirth in health care facilities (Sutarto et al., 2021) Research by Zulaika et al (2021), A study found that LBW was associated with stunting in toddlers in Tabumela Village.Out of 30 respondents, 16.7% born with LBW had short stature, while 56.7% had very short bodies.The chi square test showed a significant relationship (p < 0.05) between LBW and stunting.(Asikin, Nurdin and Ahmad, 2021) According to research by Erna Eka et al. (2019), 100% of 28 under-five LBW respondents experienced stunting.Nearly half of toddlers with normal birth weight also experienced stunting, with 46% or 24 respondents.The Chi Square test showed that p = 0.000, indicating a relationship between LBW and stunting in 385 toddlers aged 2-5 years in Jadi village, Semanding District, Tuban (Wijayanti, 2019) Research by Etin Mei's, the results showed that out of a total of 17 respondents aged 7-12 months with a history of LBW, there were 3 respondents (17.6%) with a history of LBW who did not experience stunting, and 14 respondents (82.4%) with a history of LBW who experienced stunting.This shows that the majority of children with a history of LBW will experience stunting.The results of the chi square test showed a significance result of 0.000, there was a relationship between history of LBW and the incidence of stunting in children aged 7-12 months with a p value <0.05 and with a strong relationship where the phi value was 0.603.
The results of this study are in accordance with the theory which states that one of the causes of stunting is LBW.Babies born with LBW can experience digestive tract disorders because they are not functioning properly so that food absorption is poor and electrolyte disturbances occur.LBW babies also experience problems with breastfeeding because the baby's body size is small, weak and has a small stomach and cannot suck well.As a result, the baby's growth will be disrupted, if this situation continues with inappropriate feeding, such as not exclusive breastfeeding, the child often experiences infections and grows into stunting.(Sari and Soimah, 2017) Low birth weight (LBW) is associated with stunting, and overall body weight is strongly associated with long-term growth and development.LBW can manifest as growth faltering.Early growth delay will be difficult to catch up in infants born with LBW.The growth of a child who lags behind normal growth will cause the child to experience stunting (Ode et al., 2022).Low birth weight can be caused by the mother's poor nutritional state during pregnancy, causing intrauterine growth retardation, and at birth. it is manifested by low birth weight.Long-term problems caused by LBW are stunted growth and development.Low birth weight is believed to be one of the factors causing malnutrition in the form of stunting in children (Fitri, 2018).LBW babies will grow and develop more slowly because babies with LBW have experienced intrauterine growth retardation since birth and will continue until the next age after birth, namely experiencing growth and development that is slower than babies who are born normally, and often fail to catch up with the growth rate.that should have been achieved at the age after birth.LBW also experience digestive disorders, because the digestive tract is not yet functioning, such as being unable to absorb fat and digest protein, resulting in a lack of reserves of nutrients in the body.
As a result, the growth of LBW babies will be disrupted, if this situation continues with insufficient feeding, frequent infections and poor health care will cause stunting (Dewi et al, 2020) These results confirm that LBW can be a significant risk factor in the development of stunting in toddlers.However, there are also studies such as and their interactions.Low income is influenced by several factors, such as education and work productivity.It will also have an impact on access to food, the quality of the residential environment, and access to health services, which can all impact the health status and nutritional status of children.(Lukman et al., 2021) Infants born with low birth weight or premature birth are at higher risk for negative impacts on cognitive function and childhood stunting at age 2 due to smaller brain volume compared to normal birth conditions (Upadhyay et al., 2019;Savanur et al., 2015).The meta-analysis by Upadhyay et al. (2019) found that LBW children had lower cognitive and motor scores compared to those with normal birth weight.LBW is associated with neurodevelopmental deficits, decreased brain volume, cortical changes, cell number reduction, and myelination deficits.Brain connectivity is also impaired as evidenced by nerve migration deficits, reduced dendritic processes, and less efficient neural networks (Upadhyay et al.,2019) Preterm and/or LBW babies have a higher risk of developmental delay at 2- Picture1.PRISMA Diagram (Preferred Reporting Item for Systematic Review and Meta Analysis) research by Dewi et al (2020), Gabrielisa, et al (2017), Maya et al (2021), and RR Dewi (2016), which found no relationship between birth weight and stunting in the context of the population studied.The occurrence of stunting in children can be affected by various factors, including nutrition, access to health services, sanitation, and environment.If these factors are not controlled or measured accurately in research, the results may not indicate a significant relationship between low birth weight (LBW) and stunting.It is crucial to consider other variables that can influence stunting, such as environmental factors, nutrition, socioeconomic status,
