We examined trends in pediatric hospitalization for pyelonephritis from 1985 to 2006 and identified factors associated with admission.
We performed a population based analysis of hospital discharges using the Office of Statewide Health Planning and Development database to evaluate trends in California regarding pediatric hospitalizations for pyelonephritis from 1985 to 2006. Multivariable logistic regression was performed to identify factors associated with admission for pyelonephritis.
A total of 46,300 children were hospitalized for pyelonephritis in California from 1985 to 2006. The overall rate of hospitalization for pyelonephritis increased by greater than 80%, from 17 per 100,000 children in the California population in 1985 to 31 per 100,000 in 2005. This change was primarily due to the nearly ninefold increase in pyelonephritis hospitalizations observed in children younger than 1 year, from 28 per 100,000 in 1985 to 238 per 100,000 in 2005. Among children younger than 1 year males without private insurance and of nonwhite race had increased odds of hospitalization, while females with private insurance and of Asian race had increased odds of hospitalization, compared with nonprivate insurance and white race, respectively.
A significant increase in hospital admissions for pyelonephritis, primarily in children younger than 1 year, occurred in California between 1985 and 2006. Further studies are needed to establish the cause of this striking increase and to determine why certain pediatric populations are at increased risk for hospitalization.
我们考察了 1985 年至 2006 年小儿肾盂肾炎住院治疗的趋势，并确定了与住院相关的因素。
我们利用州卫生规划和发展办公室数据库进行了基于人群的住院数据分析，以评估 1985 年至 2006 年加利福尼亚州小儿肾盂肾炎住院治疗的趋势。采用多变量逻辑回归分析确定与肾盂肾炎住院相关的因素。
1985 年至 2006 年，加利福尼亚州共有 46300 名儿童因肾盂肾炎住院。肾盂肾炎的总体住院率增加了 80%以上，从 1985 年加利福尼亚州儿童人口的每 10 万人中有 17 例增加到 2005 年的每 10 万人中有 31 例。这一变化主要是由于 1 岁以下儿童肾盂肾炎住院人数增加了近 9 倍，从 1985 年的每 10 万人 28 例增加到 2005 年的每 10 万人 238 例。在 1 岁以下的儿童中，与无私人保险和非白种人相比，男性和无私人保险和白人种族的儿童住院的几率增加，而有私人保险和亚裔种族的女性住院的几率增加，分别与无私人保险和白人种族相比。
1985 年至 2006 年期间，加利福尼亚州小儿肾盂肾炎住院人数显著增加，主要是 1 岁以下儿童。需要进一步研究以确定这一显著增加的原因，并确定为什么某些儿科人群住院风险增加。
