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.

Childhood undernutrition in North Africa: systematic review and meta-analysis of observational studies

BACKGROUND

Undernutrition remains a major public health issue in low- and middle-income countries. Objective Our aim for this study was to identify the factors contributing to undernutrition in children under five years old in North Africa.

METHODS

We searched five electronic bibliographic databases (Ovid MEDLINE, Web of Science, Embase (Ovid), ProQuest, and CINAHL) for eligible observational studies published after 2006. STATA version 17 software was used to calculate the odds ratios between associated factors and indicators of undernutrition, with 95% confidence intervals. For each factor, the overall odds were pooled using a forest plot. Due to the significant heterogeneity among the studies (I2 > 50%), a random-effects model was used, and sensitivity analysis was conducted to examine the effect of outliers.

RESULTS

Out of 1093 initially identified studies, 14 met the selection criteria. Our meta-analysis revealed that uneducated mothers were the most common factor associated with undernutrition in North African children. Children aged 0-23 months were significantly associated with stunting (odds ratios (OR) = 1.27; 95% CI: 1.18; 1.37) and wasting (OR = 1.68; 95% CI: 1.42; 1.99). Children living in rural areas were also at higher odds of being stunted (OR = 1.74; 95% CI: 1.64; 1.84) and underweight (OR = 1.59; 95% CI: 1.35; 1.88). These analyses also indicated that a lower wealth index, mothers' nutritional health, uneducated fathers, and low birth weight were other factors significantly associated with stunting.

CONCLUSION

Addressing undernutrition in Northern Africa requires a multidisciplinary approach prioritising mothers and young children, especially families in underprivileged areas.

Wasting and Underweight in Northern African Children: Findings from Multiple-Indicator Cluster Surveys, 2014-2018

Northern Africa faces multiple severe detrimental factors that impact child nutrition. This study aimed to identify the predictors for wasting and underweight in children aged 0-59 months in Northern Africa. We analysed pooled cross-sectional data from multiple-indicator cluster surveys conducted in four countries (Algeria, Egypt, Sudan, and Tunisia) involving 37,816 children aged 0-59 months. A logistic regression analysis was used, considering clustering and sampling weights, to identify factors associated with wasting and underweight among children aged 0-23, 24-59, and 0-59 months. Among children aged 0-59 months, the overall prevalence was 7.2% (95% CI: 6.8-7.5) for wasting and 12.1% (95% CI:11.7-12.5) for underweight. Sudan and Algeria had the highest rates of wasting, while Sudan and Egypt had the highest rates of underweight. Multiple regression analyses indicate that factors associated with wasting and being underweight include child age, country, rural residency, poor wealth index, being male, birth order, maternal education, body mass index, media use, lack of diverse foods, longer duration of breastfeeding, perceived small baby size, and diarrhoea. These findings highlight the importance of implementing targeted health and nutrition initiatives, such as maternal education, family planning, and community engagement. Priority should be given to children from underprivileged areas who lack proper dietary variety.

A systematic review and meta-analysis of the prevalence of childhood undernutrition in North Africa

Undernutrition (stunting, wasting and underweight) among children remains a public health concern in North Africa, especially following recent conflicts in the region. Therefore, this paper systematically reviews and meta-analyses the prevalence of undernutrition among children under five in North Africa to determine whether efforts to reduce undernutrition are on track to achieving the Sustainable Development Goals (SDGs) by 2030. Eligible studies published between 1st January 2006 and 10th April 2022 were searched for, using five electronic bibliographic databases (Ovid MEDLINE, Web of Science, Embase (Ovid), ProQuest and CINAHL). The JBI critical appraisal tool was used, and a meta-analysis was conducted using the 'metaprop' command in STATA, to estimate the prevalence of each undernutrition indicator in the seven North African countries (Egypt, Sudan, Libya, Algeria, Tunisia, Morocco, and Western Sahara). Due to the significant heterogeneity among studies (I2 >50%), a random effect model and sensitivity analysis were conducted to examine the effect of outliers. Out of 1592 initially identified, 27 met the selection criteria. The prevalence of stunting, wasting and being underweight were 23.5%, 7.9% and 12.9%, respectively. Significant variations between the countries with the highest rates of stunting and wasting were reported in Sudan (36%, 14.1%), Egypt (23.7%, 7.5%), Libya (23.1%, 5.9%), and Morocco (19.9%, 5.1%). Sudan also had the highest prevalence of underweight (24.6%), followed by Egypt (7%), Morocco (6.1%), and Libya (4.3%) with more than one in ten children in Algeria and Tunisia having stunted growth. In conclusion, undernutrition is widespread in the North African region, particularly in Sudan, Egypt, Libya, and Morocco, making it challenging to meet the SDGs by 2030. Nutrition monitoring and evaluation in these countries is highly recommended.
