Abstract

Malnutrition has historically been researched and addressed within two distinct silos, focusing either on undernutrition, food insecurity, and micronutrient deficiencies, or on overweight, obesity, and dietary excess. However, through rapid global nutrition transition, an increasing proportion of individuals are exposed to different forms of malnutrition during the life course and have the double burden of malnutrition (DBM) directly. Long-lasting effects of malnutrition in early life can be attributed to interconnected biological pathways, involving imbalance of the gut microbiome, inflammation, metabolic dysregulation, and impaired insulin signalling. Life-course exposure to early undernutrition followed by later overweight increases the risk of non-communicable disease, by imposing a high metabolic load on a depleted capacity for homoeostasis, and in women increases the risk of childbirth complications. These life-course trajectories are shaped both by societal driving factors-ie, rapidly changing diets, norms of eating, and physical activity patterns-and by broader ecological factors such as pathogen burden and extrinsic mortality risk. Mitigation of the DBM will require major societal shifts regarding nutrition and public health, to implement comprehensive change that is sustained over decades, and scaled up into the entire global food system.

  • Height and weight are affected by the quantity and quality of nutrition, energy expenditure, and some infections.

    “Height and weight are affected by the quantity and quality of nutrition, energy expenditure, and some infections.19,20”

    The paper’s “An evolutionary perspective” section (page unavailable) links dietary energy availability and diet composition to growth and weight gain; its Conclusion says infectious disease constrains linear growth. The “Intergenerational emergence of the DBM” section discusses energy sparing and fuel metabolism in relation to weight gain, but the available text does not clearly establish energy expenditure as a determinant of both height and weight. (LLM, conf=0.81)

  • In some countries, equitable economic and agricultural policies and food programmes have improved the quality of nutrition, especially for the poor, resulting in gains in height, whereas elsewhere weight gain occurred without substantial height gain, leading to increasing obesity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
