BACKGROUND Mood disorders including depression and bipolar disorders are a major cause of morbidity in childhood and adolescence, and hospitalizations for mood disorders are the leading diagnosis for all hospitalizations in general hospitals for children age 13 to 17. We describe characteristics of these hospitalizations in the U.S. focusing on duration of stay, charges, and geographic variation. METHODS The Kids' Inpatient Database was analyzed to calculate hospitalization rates for 2000, 2003, and 2006. For each year, information was available for over 2 million hospitalizations, representing 6.3 to 6.5 million hospital stays annually in acute care, non-psychiatric hospitals. RESULTS The rate of pediatric hospitalizations with a principal diagnosis of a mood disorder was 12.4/10,000 in 2000, 13.0 in 2003, and 12.1 in 2006. In the same period, the incidence of hospitalizations for depressive disorders decreased from 9.1 to 6.4/10,000 children while the incidence of hospitalizations for bipolar disorders increased from 3.3 to 5.7/10,000 children. The mean length of stay increased from 7.1 to 7.7 days, while inflation-adjusted hospital charges increased from $10,600 in 2000, to $13,700 in 2003, to $16,300 in 2006. The proportion of mood disorder stays paid by government increased from 35.3% to 45.2%. The Western region experienced the lowest rates (9.9/10,000, 11.6 and 10.2 in 2000, 2003 and 2006) while the Midwest had the highest rates (26.4, 27.6, and 25.4). CONCLUSIONS Mood disorders are a major reason for hospitalization during development, especially in adolescence. Mood disorder hospitalizations remained relatively constant from 2000-2006, but diagnoses of depressive disorders decreased while diagnoses of bipolar disorders increased. Hospitalization rates vary widely by region of the country.

2000-2006 年美国综合医院诊断为情绪障碍的儿童住院情况。

背景 包括抑郁症和双相情感障碍在内的情绪障碍是儿童期和青少年期发病的主要原因，而情绪障碍住院治疗是所有 13 至 17 岁儿童在综合医院住院治疗的主要诊断。我们描述了这些住院治疗在美国的特征关注停留时间、费用和地域差异。方法 分析儿童住院数据库以计算 2000 年、2003 年和 2006 年的住院率。每年可获得超过 200 万次住院的信息，代表每年在急症护理、非精神病医院住院的 6.3 至 650 万次。结果 主要诊断为心境障碍的儿科住院率在 2000 年为 12.4/10,000，2003 年为 13.0，2006 年为 12.1。同期，抑郁症住院率从9.1下降到6.4/10,000儿童，而双相情感障碍住院率从3.3/10,000儿童增加到5.7/10,000。平均住院天数从 7.1 天增加到 7.7 天，而通货膨胀调整后的住院费用从 2000 年的 10,600 美元增加到 2003 年的 13,700 美元，再到 2006 年的 16,300 美元。政府支付的情绪障碍住院费用的比例从 35.3% 增加到 45.2%。 . 西部地区的比率最低（2000、2003 和 2006 年为 9.9/10,000、11.6 和 10.2），而中西部地区的比率最高（26.4、27.6 和 25.4）。结论 情绪障碍是发育期间住院的主要原因，尤其是在青春期。从 2000 年到 2006 年，情绪障碍住院率保持相对稳定，但抑郁症的诊断减少，而双相情感障碍的诊断增加。住院率因国家/地区而异。
