The prevalence and trends of pulmonary nontuberculous mycobacteria (NTM)-associated hospitalizations in the United States were estimated using national hospital discharge data. Records were extracted for all persons with a pulmonary NTM International Classification of Diseases code (031.0) hospitalized in the 11 states with continuous data available from 1998 through 2005. Prevalence was calculated using US census data. Pulmonary NTM hospitalizations (031.0) increased significantly with age among both sexes: relative prevalence for persons 70-79 years of age compared with those 40-49 years of age was 15/100,000 for women (9.4 vs. 0.6) and 9/100,000 for men (7.6 vs. 0.83). Annual prevalence increased significantly among men and women in Florida (3.2%/year and 6.5%/year, respectively) and among women in New York (4.6%/year) with no significant changes in California. The prevalence of pulmonary NTM-associated hospitalizations is increasing in selected geographic areas of the United States.
利用美国全国医院出院数据，估算了美国肺部非结核分枝杆菌（NTM）相关住院率的流行趋势。从 1998 年至 2005 年，在有连续数据的 11 个州中，提取了所有肺部 NTM 国际疾病分类（031.0）编码住院患者的记录。利用美国人口普查数据计算了流行率。肺部 NTM 住院率（031.0）在两性中均随年龄增长而显著增加：与 40-49 岁年龄组相比，70-79 岁年龄组女性的相对流行率为 15/100,000（9.4 比 0.6），男性为 9/100,000（7.6 比 0.83）。佛罗里达州男女患者的年流行率均显著增加（分别为 3.2%/年和 6.5%/年），纽约州女性患者的年流行率也显著增加（4.6%/年），而加利福尼亚州则没有显著变化。在美国的一些特定地区，肺部 NTM 相关住院率正在增加。
