Metal implants are commonly used in clinical practice. However, little is known regarding the prevalence of metal implants. Therefore, this study aimed to evaluate the prevalence of metal implants in the United States (US) among individuals aged ≥ 40 years. This study conducted a serial cross-sectional analysis of US adults aged ≥ 40 years who participated in the National Health and Nutrition Examination Survey (NHANES) (2015-2016 and 2017-March 2020). Self-reported questionnaires were used to assess whether the participants had metal implants inside their bodies. The primary outcome was the prevalence of metal implants among adults aged 40 years and older. Furthermore, weighted logistic regression analysis was employed to determine the changes in the prevalence of metal implants from 2015 to March 2020. Moreover, this study investigated the variation in metal implant prevalence by demographic factors based on the pooled NHANES cycles. All analyses were conducted based on 3,736 participants from the NHANES 2015-2016 and 6,387 participants from the NHANES 2017-March 2020. This study observed a high prevalence of metal implants among adults aged 40 and older (2015-2016: 27.23%; 2017-March 2020: 31.53%). Moreover, the results of the weighted logistic regression analysis showed that the prevalence of metal implants significantly increased from 2015 to March 2020, especially among older individuals, men, and White individuals. In addition, the results of the weighted logistic regression analysis indicated that the metal implant prevalence differed by age and race/ethnicity, in which older individuals and White individuals showed a significantly higher prevalence of metal implants than younger individuals and non-White individuals, respectively. There was a high prevalence of metal implants among US adults aged 40 and older, and the prevalence of metal implants significantly increased from 2015 to March 2020. Therefore, more attention needs to be paid to this special population, and it may be necessary to ensure accessibility and affordability and assess the potential long-term health impacts of metal implants, considering the increased prevalence of metal implants.
金属植入物在临床实践中被广泛使用。然而，关于金属植入物的流行情况却知之甚少。因此，本研究旨在评估美国40岁及以上人群中金属植入物的流行情况。本研究对参与美国国家健康与营养检查调查（NHANES）（2015 - 2016年以及2017年 - 2020年3月）的40岁及以上美国成年人进行了系列横断面分析。使用自我报告问卷来评估参与者体内是否有金属植入物。主要结果是40岁及以上成年人中金属植入物的流行率。此外，采用加权逻辑回归分析来确定2015年至2020年3月期间金属植入物流行率的变化。此外，本研究基于合并的NHANES周期调查了金属植入物流行率在人口统计学因素方面的差异。所有分析都是基于2015 - 2016年NHANES的3736名参与者以及2017年 - 2020年3月NHANES的6387名参与者进行的。本研究观察到40岁及以上成年人中金属植入物的流行率很高（2015 - 2016年：27.23%；2017年 - 2020年3月：31.53%）。此外，加权逻辑回归分析结果表明，从2015年到2020年3月，金属植入物的流行率显著增加，尤其是在老年人、男性和白人中。此外，加权逻辑回归分析结果表明，金属植入物的流行率因年龄和种族/族裔而异，其中老年人和白人的金属植入物流行率分别显著高于年轻人和非白人。美国40岁及以上成年人中金属植入物的流行率很高，并且从2015年到2020年3月金属植入物的流行率显著增加。因此，需要更多地关注这一特殊人群，考虑到金属植入物流行率的增加，可能有必要确保其可及性和可承受性，并评估金属植入物潜在的长期健康影响。
