Abstract：
Dietary supplement use is common among US adults. We aimed to investigate the quantity, duration, adherence, and reasons for supplement use in individuals who take supplements. Data from 2011 to 2018 from the National Health and Nutrition Examination Survey (NHANES) dataset were analyzed. Four cycles of data were combined to estimate these outcomes. Results are presented as overall group and by subgroups. All analyses were weighted to be nationally representative. The Taylor Series Linearization approach was used to generate variance estimates. A total of 12,529 participants were included. Over 70% of these individuals reported taking more than one unit of dietary supplements daily. Notably, approximately 40% had been taking supplements for more than five years and about 67% were highly adherent to at least one supplement. However, only 26.9% of these supplements were taken following a doctor\'s recommendation. The primary reasons for dietary supplements intake included improving overall health (37.2%), maintaining health (34.7%), bone health (21.4%), and diet supplementation (20.3%). Our findings indicate that most participants proactively used multiple dietary supplements focused on self-managed health and prevention, with substantial dedication to long-term use and high adherence. Healthcare professionals should play a more active role in guiding such behaviors to optimize the health outcomes of dietary supplement users across the United States.
摘要：
膳食补充剂的使用在美国成年人中很常见。我们的目的是调查数量，持续时间,坚持,以及服用补充剂的个人使用补充剂的原因。分析了2011年至2018年国家健康与营养检查调查（NHANES）数据集的数据。合并四个周期的数据来估计这些结果。结果以总体组和亚组表示。所有分析均加权为具有全国代表性。泰勒级数线性化方法用于生成方差估计。共有12529名参与者参加。超过70％的这些人报告每天服用超过一个单位的膳食补充剂。值得注意的是,约40%的人服用补充剂超过5年,约67%的人高度坚持至少一种补充剂.然而,只有26.9%的补品是按照医生的建议服用的.膳食补充剂摄入的主要原因包括改善整体健康状况（37.2%），保持健康(34.7%)，骨骼健康（21.4%），和饮食补充（20.3%）。我们的研究结果表明，大多数参与者主动使用多种膳食补充剂，专注于自我管理的健康和预防，大量致力于长期使用和高度坚持。医疗保健专业人员应在指导此类行为方面发挥更积极的作用，以优化美国各地膳食补充剂使用者的健康结果。
