This study examined the incidence of diabetes-related hospital admissions and described the characteristics among youth and emerging adults with type 1 (T1D) and type 2 diabetes (T2D) in California.

A retrospective study was conducted using the statewide inpatient database during the years 2014–2018. Individuals aged 13–24 years hospitalized with diabetic ketoacidosis (DKA) or severe hypoglycemia (SH) were recorded. Demographic characteristics and health measures among youth (ages 13–18) and young adults (ages 19–24) were compared.

A total of 34,749 admission encounters for T1D and 3,304 for T2D were analyzed. Hospitalization rates significantly increased with age during the transition to adulthood, from 70/100,000 California population at age 17 to 132/100,000 at age 19 in T1D. Higher hospitalization rates were demonstrated in young adults than in youth in T1D, and the rate was significantly higher in Black young adults (23.9%) than in youth (12.0%) among the age-adjusted population with diabetes (P < 0.0001). More young adults admitted were on public insurance, and approximately half were from the lowest income quartile. No difference was observed in hospital length of stay; however, hospital charges were higher among young adults. Young adults were three times more likely to be admitted for severe conditions.

We demonstrated a significant rise in hospital admission during the transition period in individuals with T1D. There were significantly more Black young adults who were on public insurance and had lower socioeconomic status. Our findings suggest that the health care system fails many emerging adults with diabetes, particularly for people of color, and that improving medical transition is crucial.

本研究检查了与糖尿病相关的住院率，并描述了加利福尼亚州 1 型 (T1D) 和 2 型糖尿病 (T2D) 青年和新兴成年人的特征。

在 2014-2018 年期间，使用全州住院患者数据库进行了一项回顾性研究。记录了因糖尿病酮症酸中毒 (DKA) 或严重低血糖症 (SH) 住院的 13-24 岁个体。比较了青年（13-18 岁）和青年（19-24 岁）的人口特征和健康指标。

总共分析了 34,749 次 T1D 和 3,304 次 T2D 入院。在向成年过渡期间，住院率随着年龄的增长而显着增加，从 17 岁时的 70/100,000 加利福尼亚人口增加到 19 岁时的 132/100,000 T1D。T1D 患者的青年人住院率高于青年人，在年龄调整的糖尿病人群中，黑人青年人的住院率（23.9%）显着高于青年人（12.0%）（P < 0.0001）。更多被录取的年轻人参加了公共保险，大约一半来自收入最低的四分之一。住院时间无差异；然而，年轻人的住院费用较高。年轻人因病情严重而入院的可能性要高出三倍。

我们证明，在 T1D 患者的过渡期间，入院率显着增加。参加公共保险且社会经济地位较低的黑人年轻人明显更多。我们的研究结果表明，医疗保健系统使许多新出现的糖尿病成年人失败，特别是对于有色人种，改善医疗过渡至关重要。
