Abstract

Background

Provider delivered complementary and alternative medicine (CAM) is used increasingly as a treatment option. Nevertheless, data related to the prevalence of provider delivered CAM (or PDCAM) use in diverse racial and ethnic populations is limited. The purpose of this investigation was to describe the use of provider delivered CAM in Hawaiian, Asian, and other Pacific Island populations in Hawai'i. The investigation was undertaken to test the hypothesis that a significant difference existed in the use of provider delivered CAM in Hawai'i because of the cultural diversity existing within the population.

Methods

The data were collected through the Hawai'i Health Survey (HHS). The HHS was administered by telephone among 5,000 stratified, randomly selected households, representing each of the Hawaiian Islands. Data was collected on all members of sample households. The sample population was statistically adjusted to represent the population of Hawai'i.

Results

Several factors emerged that may indicate increased use of provider delivered CAM. Most provider delivered CAM users are more educated, have incomes 200% or more above the poverty line, and reported either good or very good health status. Among respondents with poor health status, 60.4% have used provider delivered CAM. Those with a body mass index indicating that they were overweight also reported a high level of provider delivered CAM use (51.4%). Similar percentages of both women and men use provider delivered CAM, while the youngest and oldest respondents reported the least use of provider delivered CAM. Whites (60.0%) and Koreans (56.6%) reported the highest percentage of use of provider delivered CAM, while African Americans (35.5%) and Filipinos (37.1%) report the lowest percentage. The majority of people without health insurance report provider delivered CAM use (53.7%). The highest portion of people who have used any alternative health care service is found among those whose pain severely interferes with normal work (78.3%).

Conclusions

The use of provider delivered CAM was found to be significantly greater in Hawaii compared with the mainland. Our results suggest the need for additional investigation of provider delivered CAM use in specific ethnic subpopulations.

Background

Provider delivered complementary and alternative medicine is defined as a group of diverse medical and healthcare systems, practices, and products not considered part of conventional medicine. Complementary medicine refers to therapies used with conventional medicine, and alternative medicine denotes therapies used in place of conventional medicine. According to several studies, complementary and alternative medicine (CAM) is increasingly used as a treatment option1-11. The investigators sought to: 1) Describe the use of provider delivered CAM in Hawaiian, Asian, and other Pacific Island populations in Hawai'i; 2) Explore reasons for its use within the diverse population of the state; and, 3) Compare the results with those of other surveys related to provider delivered CAM therapies. Exploration of provider delivered CAM use in Hawai'i was thought to be of particular significance because of the concentration of CAM schools in the State, state legislation favorable to provider delivered CAM, and the high concentration of immigrants who were thought to use provider delivered CAM. The investigation's focus was limited to provider delivered therapies, which require provider training or licensure, to assure some consistency in type of therapy used.

The National Institutes of Health (NIH) has categorized complementary and alternative medicine into five areas.12 This investigation explored provider delivered therapies within four of these five areas. Alternative therapies are complete systems of theory and practice that include entities such as homeopathic and naturopathic medicine. Questions on this survey explored the use of Ayruveda, Naturopathy and Curanderismo. Mind-body interventions attempt to increase the mind's capacity to affect bodily function and systems and include hypnosis and meditation. Biologically-based therapies use substances found in nature for therapy, such as dietary supplements. These therapies were not explored in this investigation. Manipulative and body-based methods are based on manipulation and/or movement of one or more parts of the body and include chiropractry, chelation, and massage. Finally, energy therapies are of two types. Biofield therapies are intended to affect energy fields that surround and penetrate the human body and include Reiki, Acupuncture and Biofeedback. Bioelectromagnetic therapies involve an unconventional use of electromagnetic fields such as pulse and magnetic fields.

Several national surveys conducted in the United States (U.S.), United Kingdom (U.K.) and Canada reveal that CAM use is steadily increasing. 1-11, 13 In 2002, 62% of adults in the U.S. were reported to have used CAM (including prayer for health) within the past 12 months, while 75% of adults reported having ever used CAM (including prayer for health).12 The reported use of CAM has grown steadily since the 1950's.

Significantly, analysis of a pre-baby boom cohort showed 3 of 10 used CAM by 30 years of age, compared with 7 of 10 in a post-baby boom cohort.14-15 In another study in Canada and the U.S., chiropractry was the most frequently used CAM therapy in both countries; use in Canada was three times higher than in the U.S. A survey in London revealed that CAM may be replacing conventional medicine in some cases, causing patients to decrease their use of conventional medicine16 The lack of data on safety and efficacy of many CAM therapies gives rise to concern and necessitates further research on CAM.

Certain CAM therapies are more utilized than others. For example, a U.S. national survey reported that 43% of adults used prayer intended to improve their own health, 24.4% used prayer intended to improve another's health, 18.9% used natural products, 11.6% used deep breathing exercises, 9.6% used a prayer group, 7.5% used chiropractry, 5.1% used yoga, 5.0% used massage, and 3.5% used diet-based therapy.13 Of the 10 most commonly used therapies, most were mind-body therapies. The same survey found that CAM was most often used to treat back pain and problems, head and chest colds, neck pain and stiffness, anxiety and depression.13

Many investigators suggest the reason for CAM use is dissatisfaction with conventional medicine. In one study, 28% of CAM users report having the belief that conventional medicine would not help resolve their health problem, while another study found that negative attitudes towards conventional medicine were not associated with use of CAM.13,15 In a national survey, 79% of CAM users stated that using both CAM and conventional therapies was better than using either one alone.16 In another study, patients with more favorable attitudes towards self-directed treatment and active behavioral involvement were somewhat more likely to choose chiropractic physicians.17 CAM use also may result from an enthusiastic approach to exploring therapies that will reduce the unpleasant effects of disease.18 One survey found that 54.9% of adults used CAM because they thought it would be interesting to try.

Factors have been identified that are associated with increased CAM use. In the latest national study, women were found to be more likely to use CAM, with the largest differential occurring in relationship to mind-body therapies. Excluding prayer in the same study, the youngest and oldest respondents reported the least use of CAM.2 Another study found factors associated with frequent use of CAM included full or partial insurance coverage (as opposed to no coverage) and using CAM therapy for wellness, back pain, or neck pain.19 A national survey found that users of both CAM and conventional medicine were more likely to be female, White, more educated, and live in the West. The same survey found that CAM users, when compared to non-users, were more likely to have poorer physical health.20 Another study found that people with diabetes, cancer, or back or neck problems were more likely to see a CAM provider. The U.S. Centers for Disease Control and Prevention reported that 29% of adults used CAM in 1999, with 10% consuming herbal medicine. Women, people with higher levels of education and income, and patients with chronic illnesses used CAM most often.

Most current data are limited to the general U.S. population, but some study on CAM use has been conducted within racial and ethnic minority groups. In the latest national survey, adult African-Americans were found to be more likely to use mind-body therapies, including prayer (68.3%), compared to adult Caucasians (50.1%) and Asians (48.1%). Adult Asians were found more likely to use CAM, excluding megavitamin therapy and prayer (43.1%) compared to adult Caucasians (35.9%) and African-Americans (26.2%). Adult Caucasians were found more likely to use manipulative and body-based therapy (12.0%) compared with adult Asians (7.0%) and African-Americans (4.4%).13 Another study reported only 3-9% of visits to CAM practitioners were by non-African-Americans.13 Finally, a pilot study found that African-American women were less likely to see a chiropractor than Hispanic or Caucasian women.21

Despite studies assessing association of CAM with various factors and prevalence in countries such as the U.S., U.K., and Canada, little data exists regarding CAM use within Asian and Pacific Islander populations. One of the few studies assessing CAM use in Hawai'i assessed cancer patients; 36% of participants had used CAM, most frequently religious or spiritual therapy. The same study found that CAM users tend to be younger, women, Catholic, and more educated.22 It also was reported that CAM users appear to report more symptoms and function less well emotionally than nonusers.13 Ethnic differences in CAM users with cancer were assessed, and Japanese participants were found less likely to use CAM than other ethnic groups.23,24

The goal of this study was to establish the prevalence of provider delivered CAM use in the general population of Hawai'i. We also sought to identify demographic factors associated with the frequency of provider delivered CAM use. The investigation was undertaken to test the hypothesis that a significant difference existed in the use of provider delivered CAM in Hawai'i because of the cultural diversity prevalent within the population. The results were then compared with findings from past national surveys that contained information related to provider delivered CAM from the U.S., U.K., and Canada. 1-12

There is increasing evidence that provider delivered CAM therapies may be effective for specific conditions.20 However use of untested provider delivered CAM modalities may have negative consequences, such as the use of ephedra. Provider delivered CAM users document that they do not share information about their use of CAM with conventional providers. Thus, information about provider delivered CAM use in ethnically diverse populations is urgently needed.

Methods

Data Source

The data were collected using the Hawaii Health Survey (HHS).25 This survey was developed by the Hawaii State Department of Health (DOH) to provide estimates describing current health status, access to and utilization of health care, and distribution of the population by age, sex, and ethnicity. The survey is administered by the Hawaii State Department of Health Office of Health Status Monitoring (OHSM), and has been conducted by SMS Research & Marketing Services, Inc. since 1995. SMS performs survey design, instrumentation, sampling, data collection, and processing. The analyses reported in this study reflect data collected for the year 2003. All estimates of percents and frequencies and associated standard errors shown in this paper were generated with SUDANN, a software package deigned to account for a complex sample design such as that used by the HHS.26 The sample population is adjusted to accurately represent people in all four counties of Hawai'i, and to statistically reflect the population of Hawai'i. Though the survey population does not include those who are homeless or without a working phone, the use of census estimates of those without telephone service and the Hawai'i Homeless Study 2003 were used to interpret the results.

The estimates reported in this paper included age groups 18-24 years, 25-44 years, 45-64 years, and 65 years and over, unless otherwise noted. This allowed for comparisons with the NHIS.

Strengths and Limitations of the Data

A major strength of the data on provider delivered CAM in the HHS is that they were collected for a representative sample of the state's population. The HHS, a telephone survey, is conducted among 5,000 stratified, randomly selected households representing each of the Hawaiian Islands. The targeted population consists of over 1.2 million civilian non-institutionalized adults residing in approximately 410,000 households. Residents of long-term care institutions, correctional facilities, and active duty Armed Forces personnel were excluded. The sample is selected each year based on a multistage cluster sample design. All questions are asked of all respondents regardless of gender, despite the fact that 65 to 70% of respondents were women. The large sample facilitated investigation of other self-reported health characteristics reported on the HHS such as health behaviors, chronic conditions, injury episodes, access to care and medical insurance coverage.

The HHS has been expanded in length and content over the years to accommodate different clients, including the DOH Family Health Division, Papa Ola Lokahi, the DOH Mental Health Division, the University of Hawai'i John A. Burns School of Medicine, Queen's Health Systems, Kamehameha Schools, and others. The survey has been specifically modified to assess provider delivered CAM use among Asian Americans, Native Hawaiians, and other Pacific Islander populations in Hawai'i.26

The provider delivered CAM questions have several limitations. First, they are dependent on the respondents' knowledge of provider delivered CAM therapies. Second, collection of data at only two points results in an inability to produce changes that can be tracked over time, and reduces reliable estimates for provider delivered CAM use for small populations subgroups. Nevertheless, these data for the two consecutive years were consistent.

Results

Use of Provider Delivered CAM

Overall, 49.9% of adults in Hawai'i were found to use provider delivered CAM services. While the NHIS data reveal that 75% of respondents used CAM for health reasons, if this estimate is corrected for prayer use, only 25% of national respondents had used provider delivered CAM therapies. Thus, the rate of provider delivered CAM in Hawai'i is significantly higher than that reported in the NHIS. Massage therapy was the most used service (31.7%), followed by chiropractry (30.4%) and acupuncture (16.2%). Table 1, below, compares these data with the most recent national data that relates to provider delivered CAM therapies.

Table 1.

Comparison of provider delivered CAM use in adults over 18 by type of therapy between Hawai'i (2003) and the United States (U.S.) 2002

Therapy Rate of Use in Hawai'i Rate of Use in U.S.
Acupuncture 16.2% 4.0%
Ayruveda 1.7% 4.0%
Biofeedback 4.3% 1.0%
Chelation 1.4% 0.1%
Chiropracty 30.4% 19.9%
Curanderismo 2.8% 1.8%
Energy Healing 6.8% 1.1%
Hypnosis 5.8% 1.8%
Massage 31.7% 9.3%
Naturopathy 10.6% 0.9%

As shown above, with the exception of Ayruveda, use of provider delivered CAM services in Hawai'i is significantly higher than rates reported in the mainland U.S. The island of Maui had the highest proportion (58.7%) of residents who had used provider delivered CAM services. Those of 1% to 24% Native Hawaiian ancestry used the highest proportion of any alternative health care services (59.9%).

Relationship of Provider Delivered CAM and Demographic Characteristics

Provider delivered CAM use also was analyzed according to age. Massage therapy is used by approximately 30% of those between 35 to 54 years and 22.9% of those 75 or older. Those >45 years of age or older had the highest proportion of overall provider delivered CAM use (54.9%).

As for gender, female and male use was comparable (51.2% and 48.4%, respectively). Massage was the provider delivered CAM therapy used most by both males (30.4%) and females (33.0%).

Provider delivered CAM use also was assessed in relation to marital status, and households with children. Married people used provider delivered CAM more frequently than unmarried couples, widows, or those who were divorced, separated, or never married. Massage therapy was used most among those who were married (30.5%). Chiropractry was used most among those who were separated, widowed, or divorced (38.4%). All provider delivered CAM therapies and specifically massage therapy was used most among those with no children under eighteen (33.5%).

Discussion

There are marked differences in provider delivered CAM use rates in Hawai'i compared to recent data based on the NHIS.13 In Hawai'i, factors associated with increased use of provider delivered CAM include:

  • the majority of CAM users are better educated

  • over 2/3 have incomes exceeding 200% of the poverty line

  • the highest percentage of users have either very good (31.6%) or good (29.2) health status

  • among respondents with a poor health status, 60.4% have used CAM

  • among respondents that are overweight, 51.4% have used CAM

  • women (52.1%) use CAM in greater frequency compared with men (47.9%)

  • the youngest and oldest respondents have the least use of CAM

  • Caucasians have the highest percentage of use of provider delivered CAM therapy

  • (60.0%), while Filipinos have the lowest percentage (37.1%)

  • people without health insurance constituted the highest portion of people who have used any CAM (53.7%)

  • the highest portion of people who have used any alternative health care service is found among those whose pain extremely interfered with normal work (78.3%)

These findings are not consistent with national data suggesting that additional investigation of ethnic factors associated with CAM use is warranted. The use of provider delivered CAM in Hawaii is significantly greater than CAM use reported on the mainland, and several factors appear to emerge. These factors need further exploration, and the potential health implications and economic consequences of CAM use should be assessed.

Conclusions

As described, the Hawai'i Health Survey has revealed that provider delivered CAM use differs significantly between Native Hawaiian, Asian and other Pacific Island populations in Hawai'i, as well as from use rates reported on the mainland. In fact, CAM use rates in Whites differ significantly from rates reported in the mainland U.S. Additional data is needed to consider both the basic and broader implications of these findings. Further investigation of correlates of CAM use in Hawaiian, Asian and other Pacific Island populations is urgently needed. Such investigation would benefit from systematic assessment of use of CAM therapies that do not require provider delivery, such as prayer and use of herbal products. Investigations also are needed to explore the possibility of relationships between CAM use and health outcomes. Ethnic factors associated with CAM use should also be considered in light of health disparities in diverse populations. Hawai'i offers unique opportunities, given the diversity of its population, the existence of CAM schools, and the prevalence of CAM use, for studying factors related to CAM use as it occurs in diverse populations.
