Risk factors for the intra-individual double burdens of malnutrition among reproductive-age women in India: a secondary analysis of three rounds of the National Family and Health Survey.

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
Introduction: Underweight, overweight/obesity and anaemia are prevalent among reproductive-age women in India, but factors affecting their intra-individual co-occurrence are unclear. Our objectives were to examine the prevalence, spatial distribution and risk factors for concurrent 'double burdens' of anaemia with underweight or overweight/obesity within the same individual. Methods: Using data from reproductive age women (15-49 years) in the Indian National Family Health Surveys 2005-2006, 2015-2016 and 2019-2021, we calculated the national prevalence of the intra-individual double burdens of malnutrition and mapped their district-level distributions. We examined the association of 28 potential risk factors with anaemia, underweight, overweight/obesity and their co-occurrence using multilevel logistic regression and calculated area under the curve (AUC) statistics. Results: The underweight-anaemia double burden affected 11%, and overweight/obesity-anaemia double burden affected 21% of women in 2019-2021. Overweight/obesity-anaemia was prevalent in northern, southern and coastal districts, while underweight-anaemia was most prevalent in central India. For underweight-anaemia, important risk factors were tobacco consumption, younger age, lower education, lower household wealth, scheduled tribe background, larger household size, region and living in a high malaria transmission area. For overweight/obesity-anaemia, risk factors included older age, being educated, higher household wealth, region and living in an area with more hot days than average in recent years. AUC statistics showed a significant role of environmental factors. Conclusions: The double burdens present significant public health challenges for India. The spatial and sociodemographic distinctness of the burdens suggests the possibility of evidence-informed targeting of programmes.
