For countries without high quality in-country data, estimates were extrapolated from similar countries matched by economy, ethnicity, geography and language. Logistic regression was used to generate smoothed age-specific diabetes prevalence estimates (including previously undiagnosed diabetes) in adults aged 20-79 years.<h4>Results</h4>The global diabetes prevalence in 2019 is estimated to be 9.3% (463 million people), rising to 10.2% (578 million) by 2030 and 10.9% (700 million) by 2045. The prevalence is higher in urban (10.8%) than rural (7.2%) areas, and in high-income (10.4%) than low-income countries (4.0%). One in two (50.1%) people living with diabetes do not know that they have diabetes. The global prevalence of impaired glucose tolerance is estimated to be 7.5% (374 million) in 2019 and projected to reach 8.0% (454 million) by 2030 and 8.6% (548 million) by 2045.<h4>Conclusions</h4>Just under half a billion people are living with diabetes worldwide and the number is projected to increase by 25% in 2030 and 51% in 2045.","journal":"Diabetes Research and Clinical Practice","year":2019,"id":818,"datarank":12.199665313903688,"base_score":9.217415285648144,"endowment":9.217415285648144,"self_citation_contribution":1.3826122928472218,"citation_network_contribution":10.817053021056466,"self_endowment_contribution":1.3826122928472218,"citer_contribution":10.817053021056466,"corpus_percentile":99.6,"corpus_rank":1036,"citation_count":10070,"citer_count":192,"citers_with_citation_signal":192,"citers_with_endowment":192,"datacite_reuse_total":0,"is_dataset":true,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2019-11-01","authors":[{"id":7877,"name":"Inga Petersohn","orcid":"0000-0002-0741-5095","position":1,"is_corresponding":false},{"id":7878,"name":"Paraskevi Salpea","orcid":null,"position":2,"is_corresponding":false},{"id":7879,"name":"Belma Malanda","orcid":null,"position":3,"is_corresponding":false},{"id":7880,"name":"Suvi Karuranga","orcid":null,"position":4,"is_corresponding":false},{"id":7881,"name":"Nigel Unwin","orcid":"0000-0002-1368-1648","position":5,"is_corresponding":false},{"id":7882,"name":"Stephen Colagiuri","orcid":"0000-0002-2398-4781","position":6,"is_corresponding":false},{"id":7883,"name":"Leonor Guariguata","orcid":"0000-0003-1682-7160","position":7,"is_corresponding":false},{"id":7884,"name":"Ayesha A.
