This study aimed to evaluate the prevalence of metal implants in the United States among individuals aged 40 years and older.
Conclusion
The prevalence of metal implants among US adults aged 40 and older was high and significantly increased from 2015 to March 2020.
Supporting Evidence
- The prevalence of metal implants was 27.23% in 2015-2016 and increased to 31.53% by March 2020.
- Older individuals and White individuals had a significantly higher prevalence of metal implants compared to younger and non-White individuals.
- The study included a total of 10,123 participants from two NHANES cycles.
Takeaway
Many adults over 40 in the US have metal implants, and this number is growing, especially among older people and White individuals.

Potential Biases

Limitations
The study relied on self-reported data, which may introduce recall bias, and did not assess the prevalence of metal implants among individuals under 40 years.
Participant Demographics
Participants were aged 40 years and older, with a mix of men and women, and included various racial and ethnic groups.
