Trends and disparities in the prevalence of circulatory disease risk factors among U.S. adults from the National Health Interview Survey database (2019-2022).

Introduction: Circulatory diseases are the leading cause of mortality in the United States (U.S)., making it crucial to understand trends and disparities in the prevalence of cardiovascular risk factors including diabetes, obesity, smoking, and hyperlipidemia. Methods: Data from the Centers for Disease Control and Prevention (CDC)'s National Health Interview Survey (NHIS) database was analyzed for adults aged 18 and older from 2019 to 2022. Prevalence percentages and Annual Percentage Changes (APCs) were calculated using regression analysis with Joinpoint, with 95 % confidence intervals (CI). The data was stratified by year, gender, age, race, nativity, veteran status, social vulnerability, employment status, and geographic distribution. Results: Among circulatory disease risk factors, obesity had the highest prevalence remaining consistent across all years. The highest obesity rates were observed amongst females, those aged 45-64, and Black or African American adults, with regional peaks in the South and Midwest. High Cholesterol, the second most prevalent risk factor, rose significantly from 20.1 % to 22 % [APC: 3.3175∗ (95 % CI: 1.1417 to 5.5416)] with males [APC: 3.3175∗ (95 % CI: 1.1417 to 5.5416)] and females [APC: 3.1315∗ (95 % CI: 3.0191 to 3.2428)] both showing significant increases over time. Furthermore, those aged >65 yrs and White adults in addition to those residing in the Northeast and South revealed the highest rates. Smoking rates remained steady, with a higher male prevalence which showed a significant decrease [APC: -5.0336∗ (95 % CI: -9.156 to -0.6731)] over time. Diabetes prevalence was stable, with males, adults aged 64 and above, American Indians and Black or African American adults and those residing in the southern region consistently showing the highest rates of incidence. Conclusion: Significant disparities and increasing trends in risk factors for circulatory diseases have been identified, highlighting the need for targeted interventions, particularly for high-risk groups such as males, older adults, veterans, and the unemployed.
