A comprehensive evaluation of incidence, deaths, disability-adjusted life-years (DALYs), and attributable risk factors related to NCDs by sex, and geographical location is essential for informing policy decisions aimed at controlling these diseases.</p><p><strong>Methods: </strong>This study used a comprehensive analysis based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023 methodology to estimate the incidence, mortality, DALYs (estimated as the sum of years of life lost and years lived with disability [YLDs]), and attributable risk factors of NCDs in Africa. Data were systematically searched for and extracted from various sources, including vital registration, verbal autopsy, surveillance systems, police reports, censuses, surveys, minimally invasive tissue sampling, and sibling history. The analysis employed the Cause of Death Ensemble model, DisMod-MR 2.1, and spatiotemporal Gaussian process regression to estimate both fatal and non-fatal health metrics associated with NCDs in Africa overall, and by region and country.</p><p><strong>Findings: </strong>In 2023, NCDs in Africa accounted for an estimated 2·33 billion (95% uncertainty interval 2·22-2·50) incident cases, 4·70 million (4·47-4·93) deaths, and 263 million (234-293) DALYs. Although absolute numbers increased between 1990 and 2023, age-standardised rates (per 100 000 population) decreased modestly: incidence rate by 2·7% (0·2-5·0), mortality rate by 9·0% (2·5-15·5), and DALY rate by 6·4% (1·2-12·0). The five leading Level 3 causes of death in Africa in 2023 were ischaemic heart disease (801 000 [653 000-965 000]), stroke (700 000 [544 000-863 000]), chronic kidney disease (293 000 [224 000-359 000], hypertensive heart disease (246 000 [170 000-337 000]), and diabetes (245 000 [190 000-314 000]) for all sexes and ages. Leading Level 2 causes of YLDs were mental disorders (30·9 million [22·0-42·2]) and musculoskeletal disorders (17·1 million [12·5-22·7]). Overall, 35·1% (32·4-38·2) of DALYs and 57·4% (54·2-60·4) of deaths due to NCDs were attributable to the 88 GBD 2023 risk factors. High systolic blood pressure contributed the largest proportion at 26·2% (21·6-30·9) of all NCD deaths in Africa, followed by dietary risks (14·7% [5·1-21·6]) and air pollution (14·2% [11·6-16·9]).</p><p><strong>Interpretation: </strong>Our findings underscore the complex and evolving nature of the NCD burden in Africa, where modest declines in age-standardised mortality and DALY rates since 1990 have been substantially offset by rising absolute counts of deaths and DALYs-a paradox driven predominantly by rapid population growth and demographic changes.

Adults aged 18 years or older with data on age, sex, wealth, and at least one cardiometabolic outcome were eligible. All variables in the surveys were obtained from standardised in-person examinations. We evaluated hypertension, diabetes, and hypercholesterolaemia and applied a care cascade of disease awareness, treatment, and control for each condition uniformly across all surveys. Disease status was defined from measured biomarkers, self-reported diagnosis, or current medication; awareness and treatment were based on self-reported information, and control on measured biomarkers. Each indicator was expressed as the proportion of all individuals with the corresponding condition. Socioeconomic position was assessed using household wealth indices derived within each survey, and participants were ranked within each country and categorised into country-specific quintiles (quintile 1 to quintile 5), with quintile 1 including those with the least household wealth. Inequality was quantified by the quintile 5 minus quintile 1 difference, the slope index of inequality (SII), and relative index of inequality (RII). Predicted 10-year cardiovascular risk was estimated with the Globorisk equations, and trial-derived relative risk reductions were applied to estimate achievable absolute risk reduction.

Inequalities widened progressively across the care cascade in all regions and were most pronounced for disease control. Pooled across regions, the SII for control was 4·4% (95% CI 2·4-6·4) for hypertension (RII 1·1, 1·1-1·2), 4·8% (0·6-9·0) for diabetes (RII 1·1, 1·0-1·2), and 6·5% (3·8-9·2) for hypercholesterolaemia (RII 1·1, 1·0-1·1).

Children who were currently receiving tuberculosis treatment, or who had received treatment within the past 3 months, were excluded. At enrolment, children were evaluated for suggestive tuberculosis symptoms (fever for >2 weeks, unremitting cough, haemoptysis and/or weight loss in the past 4 weeks, and tachycardia) and underwent Xpert MTB/RIF Ultra testing on respiratory and stool samples, chest radiography, and abdominal ultrasonography. Children were given a PAANTHER TDA score, with a score of less than 100 defined as negative and a score of 100 or higher defined as positive and prompting the initiation of treatment. At the end of the study, children were retrospectively classified by an endpoint review committee as having confirmed, unconfirmed, or unlikely tuberculosis, forming the composite reference standard against which diagnostic accuracy was assessed. The primary outcome was the proportion of children with missed tuberculosis (false negatives) among those who were not initiated on treatment as per the PAANTHER TDA. We assessed the diagnostic accuracy (sensitivity, specificity, and negative and positive predictive values) and feasibility (uptake and time to treatment initiation) of the PAANTHER TDA.
