ABSTRACT:

Rationale

Pulmonary nontuberculous mycobacteria (PNTM) are an important cause of morbidity among older adults in the United States, but national prevalence estimates are lacking.

Objectives

To describe the prevalence and trends of PNTM disease among adults aged 65 years or older throughout the United States.

Methods

A nationally representative 5% sample of Medicare Part B beneficiaries was analyzed from 1997 to 2007. Demographic and medical claims data were compiled and prevalence estimates for PNTM and selected comorbidities were calculated and trends over time evaluated. Logistic regression was used to identify demographic and geographic factors associated with PNTM.

Measurements and main results

From 1997 to 2007, the annual prevalence significantly increase
