Investing in nutrition throughout the first 8000 days of life: a multisectoral approach to supporting well-being and creating future human capital.
Review in BMJ global health, 2026. 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
Nutrition plays a fundamental role in human development, especially during critical growth periods. It is already well recognised that the first 1000 days-from conception to a child's second birthday-are vital for cognitive, physical and immune system development, and setting a child on a positive trajectory for subsequent growth. Less well recognised is the importance of the next 7000 days (ages 2-21) when good nutrition continues to be important to secure those early gains and to shape development during the next vulnerable phases, including puberty, the rewiring of the brain during adolescence and the establishment of lifelong healthy behaviours and dietary preferences. Poor nutrition during these stages can severely impact cognitive function, leading to learning difficulties, attention deficits and poor academic performance, ultimately limiting future productivity and life opportunities. The next 7000 days are a crucial phase in the development of adolescents and, by influencing their health and well-being, have profound consequences for intergenerational health and nutrition, especially for girls. Finally, to maximise opportunities for physical, cognitive, social and emotional gains during the first 8000 days, it is essential to invest in multisectoral initiatives, leveraging health, nutrition, education and early childhood development, for an integrated response.This paper draws on contemporary scientific evidence to advocate for increased investment in nutrition, not only during the first 1000 days but also throughout the next 7000 days. It examines the biological, social and economic benefits of prioritising nutrition through integrated approaches, highlighting its crucial role in breaking the cycle of intergenerational poverty. A comprehensive literature review was conducted to synthesise the latest evidence supporting greater investment in nutrition. The paper concludes with policy recommendations for coordinated action from governments, multilateral and philanthropic actors, the private sector, civil society, communities and other stakeholders to ensure sustained nutrition investment from early life through adolescence, with particular emphasis on investment in integrated, multisectoral approaches.
