Abstract

OBJECTIVE: To estimate the incidence of type 1 diabetes in all age groups in China during 2010-13. DESIGN: Population based, registry study using data from multiple independent sources. SETTING: National registration system in all 505 hospitals providing diabetes care, and communities of patients with diabetes in 13 areas across China, covering more than 133 million person years at risk, approximately 10% of the whole population. PARTICIPANTS: 5018 people of all ages with newly diagnosed type 1 diabetes and resident in the study areas from 1 January 2010 to 31 December 2013. MAIN OUTCOME MEASURES: Incidence of type 1 diabetes per 100 000 person years by age, sex, and study area. Type 1 diabetes was doctor diagnosed and further validated by onsite follow-up. Completeness of case ascertainment was assessed using the capture mark recapture method. RESULTS: 5018 cases of newly diagnosed type 1 diabetes were ascertained: 1239 participants were aged <15 years, 1799 were aged 15-29 years, and 1980 were aged ≥30 years. The proportion of new onset cases in participants aged ≥20 years was 65.3%. The estimated incidence of type 1 diabetes per 100 000 persons years for all ages in China was 1.01 (95% confidence interval 0.18 to 1.84). Incidence per 100 000 persons years by age group was 1.93 (0.83 to 3.03) for 0-14 years, 1.28 (0.45 to 2.11) for 15-29 years, and 0.69 (0.00 to 1.51) for ≥30 years, with a peak in age group 10-14 years. The incidence in under 15s was positively correlated with latitude (r=0.88, P<0.001), although this association was not observed in age groups 15-29 years or ≥30 years. CONCLUSION: Most cases of new onset type 1 diabetes in China occurred among adults. The incidence of type 1 diabetes in Chinese children was among the lowest reported in the study.

  • In China, type 1 diabetes mellitus incidence was 1.49 per 100,000 person-years among those aged ≥75 years, more than four times higher than the 0.37 per 100,000 person-years reported in a separate Chinese study.

    “In China, using a population-based registry, the incidence of T1DM was reported as 1.49 (95% CI 0.97–2.29) per 100,000 person-years among those aged ≥75 years22. This figure is more than four times higher than the incidence of 0.37 per 100,000 person-years (95% CI 0.27–0.51) reported for those aged ≥75 years in a separate Chinese study23.”

    From The epidemiology of type 1 diabetes mellitus in older adults (2025) · cites this paper as [23]

    In Results, Table 2 (page unavailable), the cited paper reports 0.37 (95% CI 0.27–0.51) per 100,000 person-years for people aged ≥75, not the 1.49 (0.97–2.29) attributed to it. The citing sentence assigns the paper’s 0.37 figure to a separate study instead. (LLM, conf=0.95)

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.
