Objective:

To investigate the prevalence of cardiovascular risk factors among South Asian adults in the U.S. compared to other racial and ethnic groups.

Key Findings:

• At age 45, 30.7% of South Asian men had prediabetes compared to 3.9% of White men.
• South Asian women had a prediabetes rate of 17.6%, higher than other groups.
• By age 55, South Asian adults were at least twice as likely to have type 2 diabetes as White adults.
• High blood pressure prevalence was 25.5% among South Asian men at age 45, higher than White, Chinese, and Hispanic men.
• Dyslipidemia was also highly prevalent among South Asian men.

Interpretation:

Cardiometabolic risk factors accumulate earlier in South Asian adults despite relatively healthy lifestyle patterns, indicating a need for proactive health screenings.

Limitations:

• Selection bias may affect results.
• Lifestyle data were self-reported, which could introduce inaccuracies.
• Differences in timing of data collection between cohorts may impact findings.

Conclusion:

The study underscores the importance of early screening for cardiovascular risk factors in South Asian populations.
