The relationship between maternal age, obesity and child mortality: a cross-sectional study using 2013-2014 Demographic and Health Survey in Democratic Republic of the Congo at national, and sub-national levels.
Article in Public health nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the relationship between maternal age and nutritional status, and test associations between maternal nutritional status and child mortality with a focus on maternal obesity.
designSecondary analysis of data from nationally representative cross-sectional sample of women of reproductive ages (15-49 years) and their children under 5 years. The outcome variable for maternal nutritional status was BMI, classified into underweight (BMI < 18·50 kg/m
settingThe most recent Demographic and Health Surveys from Democratic Republic of Congo (DRC).
participantsThe final samples consisted of 7892 women of reproductive ages (15-49 years) and 19 003 children aged 0-59 months.
resultsThe prevalence of obesity was estimated at 3·4 %; it increased with maternal age. Furthermore, obesity unevenly affected provinces in the Democratic Republic of the Congo: Kinshasa, South Kivu, North Kivu and Maniema were most affected. Finally, maternal obesity showed mixed effects on child mortality.
conclusionThe prevalence of obesity is still low; however, provinces are unevenly affected. Therefore, interventions and programmes to improve nutrition should incorporate geographical disparities to tackle adverse child outcomes associated with maternal obesity, to limit negative consequences of maternal obesity, including non-communicable diseases which might be a strong impediment to reach Sustainable Development Goals (SDG) 2 and 3.
