Socioeconomic inequality in undernutrition among late female adolescent in sub-Saharan African countries: a decomposition analysis.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionAdolescent undernutrition is a key factor influencing health outcomes. An undernourished adolescent girl who begins pregnancy with inadequate nutrient reserves often delivers low birth weight or growth-restricted infants, who is more prone to metabolic disorders in adulthood and faces higher risks of infant mortality and lower chances of survival. There is limited information on socioeconomic inequality in undernutrition among late female adolescent girls in sub-Saharan Africa. Therefore, this study aimed to assess the presence of socioeconomic inequality in undernutrition and its contributors in sub-Saharan African countries.
methodsThis study was based on recent Demographic and Health Survey of 30 Sub-Saharan African countries from 2010 to 2020. A total weighted sample of 45,598 late female adolescents was included. The Erreygers normalized concentration index and its concentration curve were applied to assess socioeconomic-related inequality in undernutrition. Decomposition analysis was conducted to identify factors contributing to socioeconomic related inequality.
resultsThe weighted Erreygers normalized concentration index for undernutrition was - 0.070 with Standard error = 0.0053 (P value < 0.0001); this revealed that undernutrition was disproportionately concentrated among the poor (pro-poor). The weighted ECI values for each country ranged from - 0.0356 in Liberia to -0.1981 in Burkina Faso, with Kenya (-0.1343), Namibia (-0.1207), and Nigeria (-0.1161) exhibiting the highest levels of inequality after Burkina Faso. The decomposition analysis revealed that wealth index (62.79%), educational level (55.84%), media exposure (40.53%) and place of residence (17.00%) were the major contributors for the pro-poor socioeconomic inequalities in undernutrition. CONCLUSION AND RECOMMENDATION: This study revealed a small but statistically significant pro-poor inequality in undernutrition among late female adolescents. Therefore, interventions should be prioritized in countries with high pro-poor inequality in undernutrition, such as Burkina Faso, Kenya, Nigeria, Namibia, and Burundi. Targeting disadvantaged late female adolescents in these countries through measures like women's economic empowerment and mass media awareness campaigns can help reduce these inequalities and contribute to achieving universal health coverage.
