To measure utilization of complementary and alternative medicine (CAM) by US adults.
We analyzed data from the 1999 National Health Interview Survey (NHIS), which covers the noninstitutionalized civilian US population. Information on 12 types of CAM use in the past 12 months was obtained from 30,801 respondents aged 18 years and older. Statistical analyses were performed using the SUDAAN software package to account for the complex sample design of the NHIS.
An estimated 28.9% of US adults used at least one CAM therapy in the past year. The three most commonly used therapies were spiritual healing or prayer (13.7%), herbal medicine (9.6%), and chiropractic therapies (7.6%). The use of CAM was most prevalent among women, persons aged 35 to 54 years, and persons with an educational attainment of > or =16 years. The overall CAM use was higher for white non-Hispanic persons (30.8%) than for Hispanic (19.9%) and black non-Hispanic persons (24.1%). Although the use was higher for persons who had health insurance than for those who did not, the difference was not statistically significant after adjusting for age, gender and educational attainment. Compared with nonusers, CAM users were more likely to use conventional medical services.
Estimates of CAM use in this nationally representative sample were considerably lower than have been reported in previous surveys. Most CAM therapies are used by US adults in conjunction with conventional medical services.
评估美国成年人补充与替代医学（CAM）的使用情况。
我们分析了1999年全国健康访谈调查（NHIS）的数据，该调查涵盖了美国非机构化的平民人口。从30801名18岁及以上的受访者中获取了过去12个月内12种CAM使用情况的信息。使用SUDAAN软件包进行统计分析，以考虑NHIS复杂的样本设计。
估计去年有28.9%的美国成年人使用了至少一种CAM疗法。三种最常用的疗法是精神疗法或祈祷（13.7%）、草药（9.6%）和脊椎按摩疗法（7.6%）。CAM的使用在女性、35至54岁的人群以及受教育程度≥16年的人群中最为普遍。非西班牙裔白人（30.8%）的总体CAM使用率高于西班牙裔（19.9%）和非西班牙裔黑人（24.1%）。虽然有医疗保险的人的使用率高于没有医疗保险的人，但在调整年龄、性别和受教育程度后，差异无统计学意义。与未使用者相比，CAM使用者更有可能使用传统医疗服务。
在这个具有全国代表性的样本中，CAM使用的估计值远低于先前调查中报告的结果。大多数CAM疗法被美国成年人与传统医疗服务结合使用。
