Prevalence of Selected Chronic Conditions Among Adults Age 45 and Older, by Age and Urbanization Level: United
Introduction:
This analysis uses 2024 National Health Interview Survey (NHIS) data to describe the percentage of adults age 45 and older who have ever had heart disease, cancer, chronic obstructive pulmonary disease (COPD), or stroke by age group and urbanization level.
Methods:
Point estimates and their corresponding variances were calculated using SAS-callable SUDAAN software to account for the complex sample design of NHIS. Differences between percentages were evaluated using two-sided significant tests at the 0.05 level. Tests for trends over urbanization levels were evaluated using logistic regression.
Key Findings:
In 2024, the prevalence of heart disease increased with decreasing urbanization level, ranging from 9.8% among adults in large central metropolitan areas to 15.2% among adults in nonmetropolitan areas. The prevalence of cancer was over two times higher among adults age 65 and older compared with adults 45-64 overall and for each urbanization level. Just over 10% of adults age 45 and older living in nonmetropolitan areas have COPD. There was variation in the percentage of adults who had a stroke by urbanization level, and the percentage was consistently higher among adults age 65 and older.
