Abstract

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.
