Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

The advantage of living in cities compared with rural areas with respect to height and BMI in children and adolescents has generally become smaller globally from 1990 to 2020, except in sub-Saharan Africa.

The archaeological site Shinfa-Metema 1 in the lowlands of northwest Ethiopia provides early evidence of intensive riverine-based foraging aided by the likely adoption of the bow and arrow.

Systematic analysis from the Global Burden of Disease study reported that, despite global improvements from 1990 to 2021, dietary iron deficiency-associated disease burden remains high in women, children and residents in low socio-demographic index countries.

Geospatial estimates of the prevalence of anemia in women of reproductive age across 82 low-income and middle-income countries reveals considerable heterogeneity and inequality at national and subnational levels, with few countries on track to meet the WHO Global Nutrition Targets by 2030.

Fine-scale geospatial mapping of overweight and wasting (two components of the double burden of malnutrition) in 105 LMICs shows that overweight has increased from 5.2% in 2000 to 6.0% in children under 5 in 2017. Although overall wasting decreased over the same period, most countries are not on track to meet the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025.

In hospitals, surfaces present as a reservoir for bacteria pathogens, potentially leading to nosocomial infections. In this work, authors aim to profile extended-spectrum β lactamase- and carbapenemase-carrying bacterial species colonising neonatal hospital wards and causing neonatal sepsis.

A high-resolution, global atlas of mortality of children under five years of age between 2000 and 2017 highlights subnational geographical inequalities in the distribution, rates and absolute counts of child deaths by age.

Authors carry out a longitudinal genomic analysis of Salmonella enterica serovar Concord isolates from various geographical locations, to reconstruct population diversity, evolution and antimicrobial resistance distribution.

A survey across 90 societies reveals that variation and change in everyday norms are explained by a single value dimension: the priority societies place on individualizing versus binding moral concerns.

Estimates from the Global Dietary Database indicated that 2.2 million new type 2 diabetes and 1.2 million new cardiovascular disease cases were attributable to sugar-sweetened beverages worldwide in 2020, with the highest burdens in sub-Saharan Africa, Latin America and the Caribbean.

An analysis based on data from the Global Dietary Database shows mean animal-sourced food intakes among children and adolescents increased modestly from 1990 to two portions per day in 2018, but remain low in sub-Saharan Africa, India and Bangladesh.

Bhattacharjee and Schaeffer et al. map exclusive breastfeeding (EBF) in 94 low- and middle-income countries (LMICs), finding increased EBF practice and reduced subnational variation across the majority of LMICs from 2000 to 2018. However, only six LMICs will meet WHO’s target of ≥70% EBF by 2030 nationally, and only three will achieve this in all districts.

Recent estimates of sugar-sweetened beverages (SSBs) intake are generally unavailable. Here the authors show a global SSBs intake of 2.7 servings/week in 2018 in adults (range: 0.7 South Asia, 7.8 Latin America/Caribbean); intakes were higher among males, younger, more educated, and urban adults.

Genomic analysis of Plasmodium vivax isolates from ten African countries reveals high diversity and distinct regional clusters, providing a foundation to investigate potential parasite adaptations to Duffy-negative hosts in subSaharan Africa.

Genomic and clinical analysis of 916 bacterial isolates from neonates with sepsis in seven low- and middle-income countries (the BARNARDS study) reveals that the main species present were antimicrobial-resistant Klebsiella, Escherichia coli and Enterobacter.

Although progress in the coverage of routine measles vaccination in children in low- and middle-income countries was made during 2000–2019, many countries remain far from the goal of 80% coverage in all districts by 2019.

To better understand the etiology of frailty, the authors perform a large genetic study. They identified 45 additional variants and implicated MET, CHST9, ILRUN, APOE, CGREF1 and PPP6C as potential causal genes, linking frailty to immune regulation, metabolism and cellular signaling.

Contrary to the view that urbanization is a major driver of the global rise in obesity, the global increase in body-mass index is shown to be mostly due to increases in the body-mass indexes of rural populations.

Dietary quality is reported at the global, regional and national level across 185 countries. Though diet quality increased modestly since 1990 at the global level, in South Asia and Sub-Saharan Africa it did not improve. In some regions, children’s dietary quality is lower than that of adults.

Modeling analysis from the Global Dietary Database estimated that 70% of new global cases of type 2 diabetes are attributable to suboptimal intake of 11 dietary factors, with substantial differences in dietary risks across world regions and nations.

Village chickens are commonplace among smallholder communities, but mortality is high. This study compares two regions in Ethiopia and finds that unique adaptations, including traits and parasite burdens, reflect distinct gene pools likely shaped by human-driven selection. Results suggest sustainable interventions for village chickens should be locally tailored.

Calls for diversity in genomics have motivated new global research collaborations across institutions with highly imbalanced resources. We describe practical lessons we have learned so far from designing multidisciplinary international research and capacity-building programs that prioritize equity in two intertwined programs — the NeuroGAP-Psychosis research study and GINGER training program — spanning institutions in Ethiopia, Kenya, South Africa, Uganda and the United States.

Understanding the emergence, evolution, and transmission of antibiotic resistance genes (ARGs) is essential to combat antimicrobial resistance. Here, Munk et al. analyse ARGs in hundreds of sewage samples from 101 countries and describe regional patterns, diverse genetic environments of common ARGs, and ARG-specific transmission patterns.

Functional diversity and phylogenetic diversity are expected to be positively correlated. Here the authors show that the covariation between these metrics in vascular plant communities around the world is often either inconsistent or negative.

Multi-ancestry genome-wide association analyses identify new risk loci for Parkinson’s disease, and fine-mapping and co-localization analyses implicate candidate genes whose expression is associated with disease susceptibility.

Obtaining data on antimicrobial resistance (AMR) from healthy human populations is difficult. Here, Hendriksen et al. use metagenomic analysis to obtain AMR data from untreated sewage from 79 sites in 60 countries, finding correlations with socio-economic, health and environmental factors.

Dry-season climate variability is a primary driver of tropical tree growth, according to observations from a pantropical tree-ring network.

The Human Cell Atlas (HCA) aims to characterize cells from diverse individuals across the globe to better understand human biology. Here, the authors lay out principles and action items that have been adopted to affirm HCA’s commitment to equity so that the atlas is beneficial to all of humanity.

A genome-wide association study suggests 41 previously unreported loci on top of the 23 known loci that influence the disease risk for lumbar disc herniations. Many of these loci harbour genes implicated in disc structure and inflammation, as well as genes related to the nervous system and nerve function.

In the first results from an ongoing global cancer screening data repository, screening program organization was better overall in Europe compared to other continents; however, there were substantial gaps in implementation across both high- and low-resource settings.

In patients with drug-resistant tuberculosis who receive treatment with new and repurposed drugs, indicators of advanced disease and delayed conversion were associated with an increased risk of reversion. These factors may be targets for close monitoring.

The Mycobacterium tuberculosis complex (MTBC) includes several pathogens thought to have originated in East Africa from an ancestor closely related to Mycobacterium canettii. Here, the authors describe a clinical tuberculosis strain isolated in Ethiopia that has typical M. canettii features but is phylogenetically much closer to the MTBC clade, supporting that the emergence of MTBC pathogens is a recent evolutionary event.
