Factors Associated with Childhood Stunting in Four North African Countries: Evidence from Multiple Indicator Cluster Surveys, 2014–2019

Stunting remains a significant public health issue among North African children, even though significant progress has been made in reducing hunger and poverty. This study aimed to identify factors associated with stunting among children in four North African countries (Algeria, Egypt, Sudan, and Tunisia). A logistic regression model adjusted for clustering and sampling weights was used to identify factors associated with childhood stunting. It was found that the prevalence of stunting in Algeria, Egypt, Sudan, and Tunisia was 9.7%(95% CI: 9.1, 10.3), 21.1% (95% CI: 19.8, 22.5), 33.8% (95% CI: 32.7, 34.9), and 8.2% (95% CI: 7.3, 9.2), respectively. Stunting was more common among children from Sudan and Egypt. Our analysis showed that a low wealth index, being a boy, low BMI, dietary diversity <5 foods, and low birth weight were associated with stunting from 0 to 23 months; however, rural residency, a low-educated mother, low BMI, family size, and diarrhea were associated with stunting from 24 to 59 months. A collaborative approach that prioritizes maternal health and nutrition, invests in struggling families, and customizes interventions to meet the specific needs of each North African country is essential for eradicating undernutrition by 2030.


Introduction
Stunting describes the hindered growth and development observed in children due to factors such as insufficient nutrition, recurring infections, and inadequate psychosocial stimulation [1].The World Health Organization defines stunting as children whose height is two standard deviations below the Child Growth Standard Median for their age group [1].Stunting has the potential to impair cognitive and school performance, reduce adult earnings and the capacity for production, and may lead to chronic diseases later in life, especially if it is accompanied by excess weight in childhood [2,3].Despite progress in some African regions, stunting remains prevalent, with 90% of stunted children in the developing world residing in Africa and Asia and 30.7% living in Africa, which is much higher than the global average of 22.0% [4].The northern and central parts of Africa have had the greatest drop in stunting [4].However, North African nations continue to contribute to the high frequency of stunting in Africa [5].According to recent data from systemic and meta-analysis research, the total pooled prevalence of stunting among children under five in North Africa is around 23.5%, which is greater than the global average of one in five [6].Even though this entire country but can also focus on specific regions.To ensure comparability, the MICS surveys employ a standardized complex sampling design, utilizing multistage stratified cluster sampling with defined selection probabilities for each primary unit.
The data used in this study were obtained from the MICS surveys conducted in Algeria (2019), Egypt (2014), Tunisia (2018), and Sudan (2014), respectively.These surveys are accessible on the website: http://mics.unicef.org/accessed on 6 January 2024.The MICS surveys serve as nationally representative surveys, gathering data on various aspects of health status, including reproductive health, maternal and child health, mortality, nutrition, and self-reported health behavior among adults [21].Eligible women for data collection were defined as all women aged 15-48 years who were either permanent residents or visitors present in the households on the night before the survey.Information on child health was collected from the mothers, specifically regarding the youngest child aged under five years.Detailed information regarding the sampling design and questionnaire can be found in the country-specific MICS reports [22].
For this study, the analysis encompassed a total of 39,983 children aged 0-59 months across the four North African countries.

Outcome Variable
The outcome variable for this study was stunting, which was determined by the height-for-age Z-score (HAZ).Stunting is an indicator of linear growth retardation and reflects cumulative growth deficits in a child.The HAZ is calculated based on the 2006 WHO growth reference, which compares a child's height to the median height of a healthy child in the same age group or reference population.It is expressed in terms of the number of standard deviations (SDs) above or below the median height [1].

Potential Covariates
The covariate variables were selected based on the UNICEF conceptual framework of the determinants of nutritional status for maternal and child health [20], which was modified according to a previous study conducted in 35 low-middle-income countries [23].These covariates were categorized into three main factors: Enabling Factors: Governance, Resources, and Norms (Country, Place of Residence, Urban/Rural) Underlying factors: socioeconomic factors (child's age, child's sex, household wealth quantile, maternal age, paternal age, maternal age at marriage, maternal level of education, maternal marital status, maternal body mass index (BMI), family size, number of children <5, and child's birth order), healthcare services factors (place of childbirth, type of delivery, delivery assistants, and number of antenatal visits), and household environment factors (sources of drinking water and toilet facilities, type of cooking fuels, and access to media).In the context of household expenses and earnings, the "Household Wealth Quantile" provides a quantitative indicator of a household's financial condition.Through the Principal Components Analysis (PCA) approach, it has been established as a quantitative representation of household assets.In order to determine a household member's ranking in the population, a score was assigned to each lawful household member after this measure was computed.There were five wealth categories in this study: poorest, poorer, middle, fourth, and richest at the national level.Poorest and poorer households made up the lowest 40% of households, middle-class households made up the next 20%, and the fourth and richest households made up the top 40% [23].
Immediate factors: dietary intake factors (early initiation of breastfeeding, ever being breastfed, duration of breastfeeding, and dietary diversity) and child health factors (perceived baby size, diarrhea, and cough in the previous two weeks).According to the guidelines for evaluating feeding practices in infants and young children published in 2021, dietary diversity was determined by adding up the variety of foods within the eight food groups that were offered within the past 24 h [24].These food categories include breast milk, grains (including roots and tubers), legumes and nuts, dairy products such as milk, yogurt, and cheese, animal-based foods such as meat, fish, poultry, and organ meats, eggs, fruits, and vegetables rich in vitamin A, as well as other varieties of fruits and vegetables [24].A child's dietary diversity variable was categorized into two categories: those who consumed five or more food groups and those who consumed less than five food groups.

Statistical Analysis
Furthermore, a weighted approach was used to balance the influence of nations with large populations, such as Egypt in 2021, with over 109 million residents, against those with lower populations, such as Tunisia in 2021, with 12.3 million residents [25].Clustering and stratification techniques based on certain nations were used to achieve this.For tabulating the survey (SVY) results, population-level weights were applied and modified for distinctive, national-specific strata, while clustering was utilized to ascertain proportions and frequency and to determine the rates of stunted children in each nation, along with 95 percent confidence intervals.
To evaluate the degree of stunting, the dependent variable was divided into two categories: category 0 for those who were not stunted (−2SD) and category 1 for those who were stunted (−2SD).Bivariable analyses were employed to explore the association between potential covariates and the study variables.In the pooled dataset analysis, three models were applied: Model 1 incorporated only the enabling factors; Model 2 represented the second stage of analysis and incorporated underlying factors alongside the enabling factors; and in Model 3, the same process was followed in the third stage, where enabling, underlying, and immediate factors were included.This hierarchical multiple regression analysis sought to compare the correlations between several groupings of characteristics while evaluating their associations with stunting in children under the age of five across the three targeted age groups.Furthermore, we conducted a country-specific analysis as reported in Tables S1-S5.
All statistical computations were conducted utilizing STATA/MP Version 17.0 (Stata Corp, College Station, TX, USA).Adjusted odds ratios (AORs) and their corresponding 95% confidence intervals (CIs) were obtained from the adjusted hierarchical multiple logistic regression models to quantify the factors associated with child stunting.The prevalence of stunting was calculated for each country, and an overall prevalence estimate (not weighted by country size) was also calculated for each country.
In our study, we focused on the presence of stunting and factors associated with it in children below age five, specifically focusing on three distinct age categories: 0-23 months, 24-59 months, and 0-59 months.This was crucial because efforts to improve childhood nutrition, encompassing practices like Infant and Young Child Feeding (IYCF), including breastfeeding and complementary feeding practices, along with promoting health awareness and psychosocial stimulation, should be directed toward children who experience stunting during both the periods of 0-23 months and 0-59 months [26].

Results
This current study included a total of 39,983 children.Characteristics of the study's weighted and unweighted samples are presented in Table 1, indicating that the weighted and unweighted samples were similar in the pooled dataset.Of this total, 52.5% lived in urban areas.More than half of the children (51.1%) were boys.The different wealth quantile categories for the four countries were almost equally represented in the sample (approximately 20% each).The lowest percentage of children was in the 18-23 months age bracket (9.2%), while the highest percentage was in the 36-41 months age bracket (11.4%).The majority of mothers came from the 20-34 years age bracket (64.1%).A large majority of the mothers (90.5%) were married, and more than 8 out of every 10 (84.8%) had a BMI less than or equal to 18.5 kg/m 2 .Most of the households (66.1%) had between 5 and 10 members, and more than half (54.5%) had two or more children under five.The minority of households used unclean cooking fuels (22.4%), unimproved drinking water (24.9%), and unimproved toilet facilities (45.1%).The majority of households (74.2%) watched television, but less than 30% (26.1) listened to the radio.Most of the children were an average size at birth (62%), did not have diarrhea in the last two weeks before the survey (83.7%), were delivered at a health facility (70.2%), their mothers had between four and seven antenatal visits (45.7%), were delivered with the aid of healthcare experts (82.4%), and were delivered without cesarean section (65.9%).The majority of the children were fed with food from less than five different food groups (70.1%), were breastfed within one hour after delivery (52.4%), were ever breastfed (85.1%), and were breastfed for a period longer than 12 months (53.3%).The number and frequency of potential variables in each country are displayed in Table S1.

Prevalence of Stunting
As shown in Figure 1, stunting was most prevalent among children in Sudan (26%) and least prevalent among children in Tunisia (8.5%), with children in Egypt (22%) and Algeria (9%) falling in between.The overall pooled prevalence of stunting among the children aged 0-23 months in the four North African countries was 16.4%.
There was a 39% prevalence of stunting among children aged 24 to 59 months in Sudan.This rate is significantly higher than the combined overall prevalence of 21.1%.The prevalence of stunting was also significant in Egypt (20%), with the lowest rates being in Algeria (10%) and Tunisia (8%), respectively.
In Sudan, children aged 0-59 months exhibited the highest prevalence of stunting at 34%, surpassing the overall pooled prevalence of 19%.Conversely, Tunisia recorded the lowest prevalence of stunting at 8%, while Egypt and Algeria fell in between, with rates of 21% and 10%, respectively.
In Sudan, children aged 0-59 months exhibited the highest prevalence of stunting at 34%, surpassing the overall pooled prevalence of 19%.Conversely, Tunisia recorded the lowest prevalence of stunting at 8%, while Egypt and Algeria fell in between, with rates of 21% and 10%, respectively.

Multivariate Analysis
Tables 2-4 present the pooled prevalence and adjusted odds ratios (aORs) for the association between stunting and potential risk factors among children under five, aged 0-23 months, 24-59 months, and 0-59 months, respectively.Conversely, Table S2 provides a detailed breakdown of the prevalence of this association within each individual country.
In the country-specific analysis (see Table S3), women with a BMI less than 18.5 kg/m 2 reported lower odds of stunting in Algeria, Egypt, and Tunisia.Children perceived by their mothers to be small reported higher odds of stunting in Sudan, Algeria, Egypt, and Tunisia.Stunting was higher among poorer and poorest households in Sudan, Algeria, Egypt, and Tunisia.Girls reported lower odds of stunting in Sudan, Algeria, and Egypt.
In the country-specific analysis of stunting among children aged 0-59 months, it was found that women with a BMI less than 18.5 kg/m 2 reported lower odds of stunting in the four countries.Additionally, households with a lower wealth index were associated with stunting in Algeria, Egypt, and Sudan (see Table S5 for details).

Discussion
This study focused on investigating the factors associated with stunting in various age groups of children under five in the North African region.The prevalence of stunting in the North African region is critically significant, as indicated by the findings of this study, which employed a combination of nationally representative data from Algeria, Egypt, Sudan, and Tunisia.The region has a higher-than-average rate of stunting, with 19.2% of children aged 0 to 59 experiencing stunting.Notably, the highest prevalence was observed among children aged 24-59 months, reaching 21.1%, which was comparable to the global figure of 21.3% [5].Our study found a glaring disparity in the prevalence of stunting among the four North African nations, which may be related to disparities in child healthcare, as well as social, economic, and cultural difficulties within and between various populations [27].
Our pooled results explored multiple areas based on the UNICEF conceptual framework categorization, which we adapted based on prior research carried out in low-middleincome countries in order to acquire a deeper knowledge of the variables causing undernutrition in the North African region [23].A number of important factors were shown to be strongly associated with stunting in this current study, including country type, place of residence, being a girl, wealth quantile, maternal level of education, maternal and paternal age, maternal BMI, family size, dietary diversity, having an illness in the last two weeks, and access to media.
Although a higher BMI in mothers was found to be a factor associated with stunting in the whole region, there was significant variation in country-specific analysis.For instance, in Sudan, a higher BMI in mothers was found to be a protective factor among children under five.However, in Algeria, Egypt, and Tunisia, it was linked to stunting among all age groups.Low birth weight, being a girl, household wealth index, children with older ages, and paternal older ages were found to be factors associated with stunting among children in more than one country.
According to the findings of this study, stunting was more prevalent in Sudan and Egypt than in Algeria and Tunisia among children under five years old in the North African area.It is important to note that none of these countries have achieved SDG 2.2, which aims for zero malnutrition.Additionally, it is concerning that the prevalence of undernutrition in this region is increasing instead of decreasing, highlighting the urgent need for focused attention on this issue both nationally and internationally [5].Our findings aligned with a recent study on stunting among children under the age of five in five South Asian countries, which also observed an increased likelihood of stunting among children in India [28].
The differences in the probability of stunting and associated factors across the four North African nations can be attributed to unfavorable factors affecting governance and available resources.In the region, these factors play a pivotal role in shaping children's nutritional well-being.Various obstacles confront North Africa countries that cause a multitude of disparities in malnutrition across the country's various regions.These challenges encompass political instability, conflicts, poverty, inequality, the impact of climate change, issues of food security, and the prevalence of infectious diseases [11][12][13][14][15][16]29].These factors collectively affect the nutritional status of individuals, especially children, in the region.Conflicts, for example, disrupt healthcare services and displace populations, leading to overcrowded and unsanitary living conditions, with limited access to healthcare, food, and clean water.Additionally, conflicts cause infrastructure destruction and disrupt supply chains, resulting in food shortages and higher prices, as well as damage to water and sanitation infrastructure, contributing to increased malnutrition among children [10,13,14,30].It is evident that conflicts have a significant impact on child health [13,15,30,31].Additionally, climate change disrupts agricultural production and reduces crop yields, leading to food insecurity and malnutrition via its impact on food diversity and availability.Children are particularly vulnerable to nutrient deficiencies, which can result in stunted growth, impaired cognitive development, and weakened immune systems [11].Libya and Sudan, for example, are among the world's most water-scarce countries as a direct consequence of climate change [32,33].
Additionally, poverty and inequality are additional potentially harmful elements that heighten these issues by reducing access to diverse and healthy foods and to healthcare and education services [30].Families living in poverty often struggle to afford a diverse and nutritious diet and face barriers in accessing healthcare services, including prenatal care, immunizations, and timely treatment of illnesses.Additionally, they frequently lack access to sanitary facilities, clean water, and good hygiene habits [16,27].Inequality in access to education, particularly for children from impoverished backgrounds, can have negative impacts on their cognitive development and overall well-being.Algeria, Tunisia, and Libya already have high rates of poverty and unemployment, and their inequalities are unevenly distributed across age groups, genders, and geographical areas [29].With Africa being the third most unequal region after Latin America and the Middle East [12,34], it is subject to significant obstacles to achieving the global goal of ending poverty by 2030.Our finding indicated that children who lived in rural areas had significantly higher odds of being stunted compared with those from urban areas, in agreement with results from past studies [28,[35][36][37].In this study, these differences could partly be due to socioeconomic differences in rural and urban settings in these countries [36].Living in a rural environment and having a mother with lower educational attainment can markedly influence the well-being of a child.A lack of access to healthcare services, including maternity and child healthcare services, in rural areas may delay the delivery of necessary medical care, increasing the danger to the mother and her child [37].Children's health in rural areas is further compromised by inadequate sanitation, poor access to nutritious foods, limited educational choices, and inadequate environments [35,37].
According to our study, the mother's education level plays an important role in determining whether older children in North Africa are at risk of growth impairments.This is consistent with many previous studies, which found an important correlation between maternal education and the level of growth impairment among children [23,28,[36][37][38][39]. Mothers with better educational backgrounds demonstrate a significant difference from those with limited or no education.Educated mothers and mothers with a better understanding of nutrition often recognize the importance of early feeding routines.In addition to their awareness of dietary habits and suitable feeding practices, they exhibit greater awareness of the importance of a child's nutritional health [38].As a result, they are able to make well-informed decisions regarding their child's nutrition and general health.Furthermore, educated mothers have a better knowledge and understanding of personal care and sanitation, which are vital for disease prevention and health maintenance.Parents' potential income can be reduced if they do not have enough education to secure stable employment.The consequences of this may include delayed or inadequate healthcare-seeking behaviors as families prioritize other fundamental needs over healthcare expenditure [38][39][40].gories were significantly less likely to experience growth impairment than males, especially in Algeria and Sudan.In the study, boys were found to be more vulnerable to growth impairment.Cultural norms have historically favored girls over boys, contributing to gender-related health disparities [41,42].Moreover, boys are often involved in a range of physical activities, consuming a considerable amount of energy that might otherwise be used for growth, while cultural norms mean girls are more likely to stay indoors, cook, do household chores, and maintain a less active lifestyle in comparison with boys.Therefore, boys are more likely to suffer from increased caloric and nutritional requirements for optimal growth and development [35].A number of cross-sectional studies have also found similar results, including in Iran [43], Kenya [44], Indonesia [45], Tanzania [46], and Ghana [47].
Children born to mothers with a higher BMI are more likely to experience stunted growth than those born to mothers with a lower BMI.This finding was consistent with a nationwide cross-sectional study conducted in Ethiopia that found a significant number of mothers in Ethiopia between the ages of 29 and 31 who are overweight or obese have stunted children [48].Overweight and obese mothers are more likely to stop breastfeeding, which can contribute to their child's stunted growth and lead to a double burden of malnutrition [49].This trend may be linked to the fact that obese women are approximately three times less likely to initiate breastfeeding compared to non-obese women [50].Ensuring adequate breastfeeding plays a crucial role in enhancing the child's overall nutritional status.
The pooled results of the study exhibited consistency with the country-specific data from Algeria, Egypt, and Tunisia.However, in Sudan, overweight was associated with higher odds of stunting and not obesity.This finding could be attributed to the fact that about three-quarters of mothers in Sudan lived in rural areas, and in developing countries, overweight and obesity are more common in urban areas than in rural areas [51,52].
According to our study, mothers aged 35-49 in this region have a protective effect against stunting among young children.Similarly, fathers aged 35-44 have a protective effect against stunting among children aged 24-59 months.These outcomes are consistent with our specific country analysis conducted in Algeria and Sudan.It is important to note that further research is recommended to determine the exact reasons behind these findings, as they could provide valuable insights for addressing the issue of malnutrition in the region.The cultural factors within these societies might play a role in explaining these effects.One possible explanation is that adolescent mothers may face more challenges in providing adequate nutrition and care for their children due to their own nutritional needs, busy lives, social responsibilities, limited resources, and lack of knowledge and experience.On the other hand, advanced maternal age brings certain advantages, such as increased socioeconomic resources, better knowledge of nutrition, and improved access to healthcare [53].Furthermore, family support within these societies can help alleviate some of the difficulties faced by mothers [54].As daughters grow older, they often become more responsible and supportive of their mothers and siblings, which can contribute to better childcare practices and improved nutritional outcomes.While maternal age tends to receive more attention in studies on child malnutrition, paternal age can also influence child nutrition outcomes.Older fathers (usually above 35 years) may possess greater socioeconomic resources and stability and may support the feeding of their babies, which can contribute to better child nutrition [55].
Poverty is positively correlated with childhood growth impairment; children from economically disadvantaged households are more likely to suffer from growth impairment than children from affluent households.The association between wealth and stunting can be attributed to the importance of wealth in acquiring nourishing food and essential goods, which promote and protect children's health.A number of past studies have demonstrated a positive association between low income and stunting in children [23,28,36,56].
Stunting was found to be positively associated with large family size in our study.Children from larger families were more likely to experience stunting.This can be attributed to the challenges of having many household members, such as limited resources for adequate childcare and lower dietary intake [57].Undernutrition in children under five can be made worse by having a large family and low income in communities, especially in communities without social security or support services for disadvantaged families.These results were consistent with prior research [58,59] that proved an association between stunting and bigger family sizes.In families with more children, the caregiver-to-child ratio may be higher.This can affect the quality of care and attention given to each child, including feeding practices, hygiene, and stimulation, which are crucial for healthy growth and development [60].
Our pooled results strongly support the significant association between stunting among children in North Africa and insufficient intake of diverse foods, which aligned with the findings of A kombi et al. [35] in their study conducted in the sub-Saharan region.Malnutrition can occur when there is inadequate consumption of macronutrients (proteins, carbohydrates, and fats) and essential micronutrients (vitamins and minerals) [61].The absence of nutrient-rich foods and inadequate dietary diversity not only leads to undernutrition but also compromises immunity and increases reoccurrence of and susceptibility to illnesses.Furthermore, our study revealed a significant association between stunting in children aged 0-59 months who had experienced diarrhea in the two weeks preceding the surveys.This finding was consistent with previous research indicating that both the cumulative incidence and longitudinal prevalence of diarrhea are strongly linked to stunting prevalence [62].The persistence or recurrence of diarrhea can lead to depletion of nutrients, decreased nutrient absorption, and increased metabolic demands, thereby contributing to wasting and underweight status.Diarrhea is commonly linked to inadequate hygiene practices, polluted water sources, limited access to medical care, and subpar sanitation facilities [63].It is imperative to observe that these factors frequently function within a vicious cycle.Insufficient dietary consumption has the potential to undermine a child's immune system, rendering them more susceptible to infections like diarrhea [62][63][64].
Maternal exposure to radio and/or television was associated with a significantly lower probability of stunting among children aged 0-59 months in our pooled results relative to those whose mothers did not utilize these media.This association was particularly significant in Algeria and Sudan, where maternal exposure to television was linked with a reduced incidence of stunting among children.
Electronic or print media exposure still remains a crucial means of disseminating health-related programs, such as the advantages of breastfeeding, immunization, and complementary feeding [65], thereby making it a vital source of health information.
This study had both strengths and limitations.One of the study's strengths was its exclusive focus on undernutrition within North Africa, which allowed for a comprehensive analysis of the contributing factors.Through a focus on this particular region, we were able to acquire a more profound understanding of the challenges, circumstances, and contextual factors that contribute to undernutrition in this area.We carefully examined the determinants linked to stunted growth in children under the age of five across three distinct age groups, specifically 0-23 months, 24-59 months, and 0-59 months.Nevertheless, the study had certain limitations; in terms of methodology, the current study's cross-sectional design restricted our capacity to deduce causation.Additionally, certain data relied on self-reported information, such as the reported birth weight of the children.Furthermore, the outcomes of the study might have been affected by confounding variables that were not thoroughly examined in the analysis.
This study highlighted the pressing need for action and underscored the importance of collaboration between national and international governments and policymakers to prioritize nutrition.It advocated for the application of a comprehensive strategy to tackle undernutrition and involved the creation of individualized plans tailored to the specific context while considering the identified factors that contribute to the problem.One of the strategies that may be employed is the implementation of social safety nets to aid in the access to food in rural areas and regions affected by conflicts.Implementation of multi-year transfers consisting of food, money, or a mixture of both would provide assistance to underprivileged regions [17].Improved water, sanitation, and hygiene (WASH) in community-based interventions could enhance the protection of children against diarrheal infections.It is imperative to recognize the complex contributing factors to stunting in each country in the region and to develop interventions that are customized to meet the specific needs of each region.
Additionally, this study emphasizes the significance of promoting peace, improving resilience to climate change, reducing poverty, and guaranteeing fair availability of nourishing food.The nutritional status and overall health outcomes of vulnerable populations can be improved by investing in healthcare, education, and social safety nets.Another significant implication of these actions is the creation of evaluation and monitoring systems to measure the effectiveness of interventions and follow progress over time.Consistently collecting and analyzing data can provide insights into intervention impacts, allowing policymakers to adjust strategies and make informed decisions [66].

Conclusions
In conclusion, the high prevalence of undernutrition stunting in North Africa is a major concern that needs to be addressed.The area is currently subject to various difficulties that include political instability, poverty, disparity, climate change, and pandemics, all of which augment malnutrition and cause food insecurity.Addressing child undernutrition in North Africa requires a comprehensive and multi-sectoral approach tailored to the specific needs of each individual country.Addressing undernutrition among disadvantaged families and areas, particularly maternal health and nutrition, should be the focus of interventions, programs, and policies to effectively tackle this issue.Better healthcare access and parental education on family planning and maternal/child health could make this possible.Combating undernutrition also involves empowering women, enhancing community-based programs, and promoting equitable economic opportunities.A holistic approach that covers these essential aspects could significantly reduce undernutrition and improve children's overall well-being in the area.
