Ethnic differences in use of complementary and alternative medicine at midlife: longitudinal results from SWAN participants

Complementary and alternative medicine for mental disorders among African Americans, black Caribbeans, and whites

OBJECTIVES

This study examined racial and ethnic differences in the use of complementary and alternative medicine (CAM) for the treatment of mental and substance use disorders.

METHODS

Data were from the National Survey of American Life (NSAL) and the National Comorbidity Survey-Replication (NCS-R). The analytic sample included 631 African Americans and 245 black Caribbeans from the NSAL and 1,393 non-Hispanic whites from the NCS-R who met criteria for a mood, anxiety, or substance use disorder in the past 12 months. Logistic regression was used to examine racial and ethnic differences in the use of any CAM and in the use of CAM only versus the use of CAM plus services in another treatment sector.

RESULTS

Thirty-four percent of respondents used some form of CAM. Whites were more likely than blacks to use any CAM, although there was no racial or ethnic difference in CAM use only versus CAM use plus traditional services. A higher proportion of blacks than whites used prayer and other spiritual practices. Among those with a mood disorder, black Caribbeans were less likely than African Americans to use any CAM.

CONCLUSIONS

Findings of this study were similar to those of previous studies that examined physical illness in relation to CAM use in terms of its overall prevalence, the predominant use of CAM in conjunction with traditional service providers, and racial and ethnic differences in the use of CAM. The use of prayer was a major factor in differences between blacks and whites in CAM use; however, there were also differences among black Americans that warrant further research.

Complementary and alternative therapy use before and after breast cancer diagnosis: the Pathways Study

Many women use complementary and alternative medicine (CAM) to maintain or improve their health. We describe CAM use among the first 1,000 participants enrolled in the Pathways Study, an ongoing prospective cohort study of women diagnosed with breast cancer (BC). Participants, identified by rapid case ascertainment in Kaiser Permanente Northern California, are women > or = 21 years diagnosed with first invasive BC. Comprehensive baseline data are collected on CAM use through in-person interviews. Study participants include 70.9% non-Hispanic whites, 10.2% Hispanics, 9.0% Asians, 6.5% African-Americans, and 3.4% others. Most women (82.2%) were diagnosed with AJCC stage I/II BC at average (+/-SD) age 59.5 (+/-12.0) years and reported prior use of at least one form of CAM (96.5% of participants). In the 5 years before diagnosis, CAM therapies used at least weekly by >20% of women included green tea, glucosamine, omega-3 fatty acids, prayer and religion. CAM use was high (86.1% of participants) in the period immediately following diagnosis; 47.5% used botanical supplements, 47.2% used other natural products, 28.8% used special diets, 64.2% used mind-body healing, and 26.5% used body/energy/other treatments. In multivariable analyses, frequent use of each CAM modality before and after diagnosis was associated with use of other CAM modalities and other health behaviors (i.e., high fruit/vegetable intake, lower BMI). CAM use before and after BC diagnosis is common in this diverse group of women. Our results emphasize the need for clinicians to discuss CAM use with all BC patients.

Preventive screening of women who use complementary and alternative medicine providers

BACKGROUND

Many women use complementary and alternative medicine (CAM). Although CAM use has been associated with reductions in conventionally recommended pediatric preventive care (e.g., vaccination), little is known about associations between CAM use and receipt of recommended preventive screening in women.

METHODS

Using Washington State insurance data from 2000 to 2003, the authors generated clustered logistic regression models, examining associations between provider-based CAM use and receipt of screening tests for Chlamydia trachomatis, breast cancer, and cervical cancer: (1) contrasting women who used CAM providers only (alternative use) and women who used both conventional and CAM providers (complementary use) with women who used conventional care only and (2) testing associations between screening and use of four specific CAM provider types-naturopathic physicians, chiropractors, massage therapists, and acupuncturists.

RESULTS

Both alternative and complementary use was associated with reduced Chlamydia screening. Cancer screening increased with complementary use but decreased with alternative use of CAM. Use of naturopathy was associated with decreased mammography, whereas all four CAM therapies were positively associated with Papanicolaou testing.

CONCLUSIONS

When used in conjunction with conventional care, use of provider-based CAM may signal high interest in various types of health-promoting behavior, including cancer screening. Negative associations between CAM and Chlamydia screening and between naturopathy and mammography require additional study. Interventions with CAM providers and their patients, aimed at improving rates of conventionally recommended screening, might encourage greater focus on preventive care, an important task when CAM providers serve as women's only contact with the healthcare system.

A multivariate test of an expanded Andersen Health Care utilization model for complementary and alternative medicine (CAM) use in African Americans

OBJECTIVES

The objectives of this study were (1) to determine which Andersen Model variables [predisposing, enabling, and need (PEN)] are related to complementary and alternative medicine (CAM) use by African Americans in the past 12 months; and (2) to determine whether the addition of disease states to the Model will explain significant variation in CAM use in the past 12 months.

DESIGN

The 2002 National Health Interview Survey was used with 4256 African American adults (n = 23,828,268 weighted) selected as the study population. The dependent variable, CAM Past 12 Months, represented participants' use of at least 1 of 17 CAM modalities during the past 12 months. The Andersen Model variables [predisposing (e.g., age); enabling (e.g., insurance); and need (e.g., medical conditions)] and prevalent disease states (> or =10%) comprised the independent variables. Logistic regression analyses, incorporating the sampling weights, were employed.

RESULTS

Among predisposing factors, CAM use was associated with middle-aged to older, more educated, and female African Americans. Region (Northeast less likely than South) was the only significant enabling factor. Need factors had the most frequent relationships, with more medical conditions, more physician visits, better health status, prescription and over-the-counter medication use, more frequent exercise, and having activities of daily living limitations being associated with CAM use. After adjusting for PEN factors, the disease states of pain/aching joints, recurring pain, and migraine were related to CAM use.

CONCLUSIONS

African American CAM users are middle-aged to older, female, educated, and have more medical conditions (especially pain-related). Users report higher utilization of "traditional" care (e.g., physician visits), indicating that CAM is likely a complement to conventional treatment in this population. Health care providers should use these factors as prompts for inquiring about CAM use in African American patients.

Duration of vasomotor symptoms in middle-aged women: a longitudinal study

OBJECTIVE

Vasomotor symptoms adversely affect the quality of life and functional status of most women during the menopausal transition, but little is known about how long these symptoms last. The most effective treatment, hormone therapy (HT), carries risks and benefits that depend on the timing and duration of use. In this study we sought to estimate the duration of vasomotor symptoms in a longitudinal study.

METHODS

We reanalyzed primary data from 438 women in the longitudinal cohort of the population-based Melbourne Women's Midlife Health Project. Two hundred and five women who had completed 13 years of follow-up were included in the analyses. The onset and cessation of vasomotor symptoms were reported, stratifying analyses according to ever use of HT. Symptom duration was calculated as the time between the first and last bothersome hot flush reported.

RESULTS

The mean (SD) duration of bothersome menopausal symptoms for women who completed 13 years of follow-up and who never used HT was estimated to be 5.2 (3.8) years (median, 4 years). If women who used HT were included, the mean (SD) duration was 5.5 (4.0) years (median, 4 years). The estimated duration of symptoms varied according to the duration of longitudinal follow-up, with a mean estimate of 3.4 years (median, 3 years) when only 8 years of follow-up data were analyzed. The only factor associated with duration of hot flushes was regular exercise-more exercise was associated with shorter symptom duration.

CONCLUSIONS

The average duration of vasomotor symptoms in this sample is more than 5 years, substantially longer than had been previously reported.

'They don't ask me so I don't tell them': patient-clinician communication about traditional, complementary, and alternative medicine

PURPOSE

Although high rates of traditional medicine and complementary and alternative medicine (TM/CAM) use have been well documented, there has been less attention to the factors influencing communication between patients and their primary care clinicians about TM/CAM. Such communication can be important in anticipating possible drug-herb interactions and in assuring agreement about therapeutic plans.

METHODS

We used sequential, multistage, qualitative methods, including focus groups, in-depth interviews, and a video vignette, to explore communication about TM/CAM between patients and their primary care clinicians. The study was conducted in RIOS Net (Research Involved in Outpatient Settings Network), a Southwestern US practice-based research network, situated largely in Hispanic and American Indian communities where TM/CAM is an important part of self-care.

RESULTS

One hundred fourteen patients, 41 clinic staff members, and 19 primary care clinicians in 8 clinic sites participated. The degree and nature of TM/ CAM communication is based on certain conditions in the clinical encounter. We categorized these findings into 3 themes: acceptance/nonjudgment, initiation of communication, and safety/efficacy. Perceived clinician receptivity to and initiation of discussion about TM/CAM strongly influenced patients' decisions to communicate; perceived clinician expertise in TM/CAM was less important. Clinicians' comfort with patients' self-care approaches and their level of concern about lack of scientific evidence of effectiveness and safety of TM/CAM influenced their communication about TM/CAM with patients.

CONCLUSIONS

Specific communication barriers limit patient-clinician communication about TM/CAM. Clinicians who wish to communicate more effectively with their patients about these topics and better integrate the types of care their patients use can change the communication dynamic with simple strategies designed to overcome these barriers.

Role of religiosity and spirituality in complementary and alternative medicine use among cancer survivors in California

OBJECTIVES

Cancer survivors often turn to religion, spirituality, and complementary and alternative medicine (CAM) because they perceive these areas as being more holistic and patient-centered than conventional medicine. Because increased religiosity and spirituality have been found to be associated with higher CAM use in the general population, it was hypothesized that these factors would be important predictors of CAM use in cancer survivors.

DESIGN AND SUBJECTS

The study included a subsample of 1844 people with cancer or a history of cancer from the 2003 California Health Interview Survey of CAM, a cross-sectional survey of a population-based sample of adults in California. Prevalence and predictors of religious/spiritual forms of CAM (R/S CAM) and nonreligious/nonspiritual forms of CAM (non-R/S CAM) were compared. Multivariate logistic regression was used to identify the predictors of R/S CAM and non-R/S CAM.

RESULTS

Nearly two thirds of participants reported using at least 1 type of R/S CAM, and 85% reported ever using non-R/S CAM. The majority of cancer survivors reported that they were very/moderately religious or spiritual. Both religiosity and spirituality were strongly related to non-R/S CAM use, but in opposite directions. Very or moderately religious cancer survivors were less likely (odds ratio=0.30; 95% confidence interval, 0.12-0.40) than nonreligious cancer survivors to use non-R/S CAM. In contrast, very or moderately spiritual cancer survivors were more likely (odds ratio=2.42; 95% confidence interval, 1.16-6.02) than nonspiritual cancer survivors to use non-R/S CAM.

CONCLUSIONS

The use of R/S CAM and non-R/S CAM is very high in cancer survivors. It may be helpful for clinicians to ascertain their patients' use of these types of CAM to integrate all forms of care used to managing their cancer.

A longitudinal analysis of older Australian women's consultations with complementary and alternative medicine (CAM) practitioners, 1996-2005

OBJECTIVE

to determine the factors associated with complementary and alternative medicine (CAM) use among older Australian women over time.

METHODS

a longitudinal analysis of postal questionnaires completed in 1996, 1999, 2002 and 2005 as part of the Australian Longitudinal Study on Women's Health.

RESULTS

the percentage of women who consulted a CAM practitioner in the years 1996, 1999, 2002 and 2005 were 14.6%, 12.1%, 10.9% and 9.9%, respectively. Use of CAM increased as the number of reported symptoms increased and physical health deteriorated, for non-urban residents compared to urban residents.

CONCLUSION

use of CAM amongst older women appears to be strongly influenced by poor physical health. There is also a suggestion that lack of access to conventional health care providers increases CAM use. There is also an overall decline in the use of CAM among older women as they age.

The use of complementary and alternative medicine among Chinese Canadians: results from a national survey

This study examines the relationship between Chinese Canadian ethnicity and the use of complementary and alternative medicine (CAM) and explores some of the factors that contribute to CAM use among this visible minority group. Using data from cycle 2.1 of the Canadian Community Health Survey (2003), we use multivariate logistic regression to investigate the extent to which CAM use varies among Chinese Canadians and non-Chinese Canadians. Two three-way interactions, which demonstrate how the combination of certain identity markers increases their predictive value within the model, are also examined. The use of CAM varies according to ethnicity, with Chinese Canadians being more likely to use than non-Chinese Canadians. The findings also indicate that cultural factors play a key role in establishing the necessary conditions for increasing the likelihood of CAM use for Chinese Canadians. Findings are discussed in terms of their implications for health care policy and program development.

Complementary and alternative medicine use among Chinese and white Canadians

ABSTRACTOBJECTIVEThis study aimed to describe the level of complementary and alternative medicine (CAM) use and the factors associated with CAM use among Chinese and white Canadians.DESIGNA cross-sectional telephone survey conducted in English, Cantonese, and Mandarin.SETTINGCalgary, Alta.PARTICIPANTSChinese and white residents of Calgary aged 18 or older.MAIN OUTCOME MEASURESRates of use of 11 CAM therapies, particularly herbal therapy, massage, chiropractic care, and acupuncture; reasons for use of CAM therapies.RESULTSSixty percent of 835 Chinese respondents (95% confidence interval [CI] 56.5% to 63.2%) and 59% of 802 white respondents (95% CI 55.1% to 62.0%) had used CAM in the past year. Chinese respondents were more likely to use herbal therapy than white respondents were (48.7% vs 33.7%, P < .001), less likely to use massage (17.1% vs 30.4%, P < .001) and chiropractic care (8.4% vs 21.2%, P < .001), but equally likely to use acupuncture (8.3% vs 7.9%, P = .173). The common factor associated with herbal therapy, acupuncture, or massage use among Chinese and white respondents was receiving a CAM recommendation from a family member or friend. Factors unique to either Chinese or white CAM users varied by therapy. For example, herbal therapy use for Chinese respondents was associated with the presence of chronic disease (adjusted odds ratio [AOR] 2.15, 95% CI 1.09 to 4.24 for having 3 diseases compared with those without chronic disease), beliefs about the effectiveness of herbal therapy (AOR 1.56, 95% CI 1.12 to 2.17), and trust in herbal therapy practitioners (AOR 1.72, 95% CI 1.24 to 2.37). Herbal therapy use for white respondents was associated with the beliefs that herbal treatment had fewer side effects than prescription drugs (AOR 1.81, 95% CI 1.31 to 2.50) and that herbalists took a holistic approach (AOR 2.07, 95% CI 1.49 to 2.87).CONCLUSIONWhile the percentage of CAM use was similar in both groups, Chinese Canadians mainly used herbal therapy and white Canadians used a range of CAM therapies. Factors associated with CAM use varied with ethnicity and type of CAM therapy. Presence of chronic disease, however, was an important factor for Chinese Canadians. That finding suggests that Chinese Canadians use CAM for the treatment of chronic disease, while white Canadians use such therapies for disease treatment and health maintenance.

Health practices and vaginal microbicide acceptability among urban black women

BACKGROUND

Intravaginal topical microbicides are being investigated for prevention of HIV transmission. Use of vaginal microbicides will constitute a new type of practice, occurring in the context of other vaginal practices related to contraception, hygiene, and self-care, which are affected by cultural norms and personal beliefs. Given the high rate of HIV infection among black women, research on practices and decision making relevant to microbicide acceptability is needed in this population.

METHODS

Twenty-three black women in New York City, aged 25-64, completed in-person semistructured interviews and self-administered questionnaires. Quantitative analyses examined vaginal practices and willingness to use microbicides. Qualitative analyses explored underlying decision-making processes involved in choices regarding vaginal practices and general healthcare.

RESULTS

Willingness to use vaginal products for HIV prevention was high, especially among more educated women. Safety was a major concern, and women were cautious about using vaginal products. Whereas some viewed synthetic products as having potentially harmful side effects, others perceived natural products as risky because of insufficient testing. Choices about vaginal practices were affected by assessments of risk and efficacy, prior experience, cultural background, and general approach to healthcare.

CONCLUSIONS

The majority of women in the sample expressed willingness to use a vaginal product for HIV prevention. Decision-making processes regarding vaginal practices were complex and were affected by social, cultural, and personal factors. Although specific preferences may vary, attitudes toward using a vaginal product are likely to be positive when side effects are minimal and the product is considered safe.

Medical pluralism among American women: results of a national survey

BACKGROUND

Medical pluralism can be defined as the employment of more than one medical system or the use of both conventional and complementary and alternative medicine (CAM) for health and illness. American women use a variety of health services and practices for women's health conditions, yet no national study has specifically characterized women's medical pluralism. Our objective was to describe medical pluralism among American women.

METHODS

A nationally representative telephone survey of 808 women >or=18 years of age was conducted in 2001. Cross-sectional observations of the use of 11 CAM domains and the use of an additional domain--spirituality, religion, or prayer for health--during the past year are reported. Women's health conditions, treatments used, reasons for use, and disclosure to conventional physicians are described, along with predictors of CAM use.

RESULTS

Over half (53%) of respondents used CAM for health conditions, especially for those involving chronic pain. The majority of women disclosed such practices at clinical encounters with conventional providers. Biologically based CAM therapies, such as nutritional supplements and herbs, were commonly used with prescription and over-the-counter (OTC) pharmaceuticals for health conditions.

CONCLUSIONS

Medical pluralism is common among women and should be accepted as a cultural norm. Although disclosure rates of CAM use to conventional providers were higher than in previous population-based studies, disclosure should be increased, especially for women who are pregnant and those with heart disease and cancer. The health risks and benefits of polypharmacy should be addressed at multiple levels of the public health system.

Use of complementary and alternative therapies by overweight and obese adults

OBJECTIVE

Obesity is associated with higher health-care costs due, in part, to higher use of traditional health care. Few data are available on the relationship between obesity and the use of complementary and alternative medicine (CAM).

METHODS AND PROCEDURES

We analyzed data on CAM use from the 2002 National Health Interview Survey (NHIS) Alternative Medicine Supplement (n=31,044). We compared the use of CAM overall, within the past 12 months, between normal weight (BMI from 18 to <25), overweight (from 25 to <30), mildly obese (from 30 to <35), moderately obese (from 35 to <40), and extremely obese (>40) adults. For the primary analysis, our multivariable model was adjusted for sociodemographic factors, insurance status, medical conditions, and health behaviors. We performed additional analyses to explore the association of BMI and the use of seven CAM modalities.

RESULTS

We found that adults with obesity have lower prevalence of use of yoga therapy, and similar prevalence of use of several CAM modalities, including relaxation techniques, natural herbs, massage, chiropractic medicine, tai chi, and acupuncture, compared to normal-weight individuals. After adjustment for sociodemographic factors, insurance status, medical conditions, and health behaviors, adults with obesity were generally less likely to use most individual CAM modalities, although the magnitude of these differences were quite modest in many cases.

DISCUSSION

Even though adults with obesity have a greater illness burden and higher utilization of traditional medical care, adults with higher BMIs were no more likely to use each of the individual CAM therapies studied. Additional research is needed to improve our understanding of CAM use by adults with obesity.

The Pathways Study: a prospective study of breast cancer survivorship within Kaiser Permanente Northern California

OBJECTIVE

With 2.3 million breast cancer survivors in the US today, identification of modifiable factors associated with breast cancer recurrence and survival is increasingly important. Only recently new studies have been designed to examine the impact of lifestyle factors on prognosis, including Pathways, a prospective study of women with breast cancer in Kaiser Permanente Northern California (KPNC).

METHODS

Pathways aims to examine the effect on recurrence and survival of (1) lifestyle factors such as diet, physical activity, quality of life, and use of alternative therapies and (2) molecular factors such as genetic polymorphisms involved in metabolism of chemotherapeutic agents. Eligibility includes any woman diagnosed with invasive breast cancer within KPNC, no previous diagnosis of other invasive cancer, age 21 years or older, and ability to speak English, Spanish, Cantonese, or Mandarin. Newly diagnosed patients are identified daily from electronic pathology records and are enrolled within two months of diagnosis. An extensive baseline interview is conducted, blood and saliva samples are collected, and body measurements are taken. Women are followed for lifestyle updates, treatment, and outcomes by self-report and query of KPNC databases.

RESULTS

Recruitment began in 9 January, 2006, and as of 16 January, 2008, 1,539 women have been enrolled along with collection of 1,323 blood samples (86%) and 1,398 saliva samples (91%).

CONCLUSIONS

The Pathways Study will become a rich resource to examine behavioral and molecular factors and breast cancer prognosis.

Complementary and alternative medicine for menopause: a qualitative analysis of women's decision making

BACKGROUND

While almost half of women use complementary and alternative medicine (CAM) during their menopause, almost no literature explores why women choose CAM for menopausal symptoms. Clinician-patient conversations about CAM can be unsatisfactory, and exploration of women's choices may benefit communication.

OBJECTIVE

The objective of this study was to describe women's choices to use CAM for menopausal health issues.

DESIGN

This is a qualitative study utilizing semi-structured interviews.

PARTICIPANTS

Convenience sample of 44 menopausal women ages 45 to 60 recruited in two primary care clinics. Both users and non-users of CAM were included.

APPROACH

Transcripts of semi-structured interviews were analyzed for themes that were refined through comparison of labeled text.

MAIN RESULTS

Four themes emerged in decisions to use CAM: (1) valuing CAM as "natural", although the meaning of "natural" varied greatly, (2) perceiving menopause as marking a change in life stage, (3) seeking information about menopause generated from personal intuition and other women's experiences, and (4) describing experiences before menopause of using CAM and allopathic medication in patterns similar to current use (patterned responses).

CONCLUSION

Women's decisions about using CAM during menopause can be understood through their perspectives on menopause and overall health. Increased clinician awareness of these themes may promote supportive discussions about CAM during counseling for menopause.

Patterns of natural herb use by Asian and Pacific Islanders

OBJECTIVE

Previous studies have noted the role of race/ethnicity in use of complementary and alternative medicine (CAM). Asian and Pacific Islanders (APIs) in particular have been found to use herbs more frequently, although the patterns of use among this population have not been described. The goal of this study was to characterize the rates and patterns of herb use among the API population of the United States.

DESIGN

Data from the 2002 US National Health Interview Survey, including the supplement on CAM, were analyzed using SAS. Cross-tabulation and logistical regression were used to determine the association between herb use and race/ethnicity, while adjusting for demographic factors.

RESULTS

After adjusting for age, gender and educational attainment, we found that APIs were more likely to use herbs than non-Hispanic Whites (OR=1.3; 95% CI: 1.1, 1.5; p=0.013), with the difference being most prominent in those 60 years old or older (OR=2.9; 95% CI: 1.8, 4.5; p<0.0001). Herb use among APIs was more common among women, those with higher education and income, and those in older age groups. Patterns of use also varied among API subgroups, with Chinese Americans reporting the highest rates of herb use in their lifetimes (44%) and in the previous 12 months (33%).

CONCLUSION

Considerable diversity exists within API subgroups with regard to the prevalence and demographic and health correlates of natural herb use. Herb use is more common among APIs than non-Hispanic Whites, particularly among the elderly. The disaggregation of APIs by racial/ethnic subgroups may be important for patient-health care professional interactions, and when designing studies of racial/ethnic minority populations.

Patterns of complementary and alternative medicine use in African Americans

OBJECTIVES

This study sought to determine (1) characteristics of complementary and alternative medicine (CAM) users in the African-American (AA) population; (2) the prevalence of CAM use; and (3) CAM use for treatment and prevention of disease.

DESIGN

The authors analyzed data from the 2002 National Health Interview Survey (NHIS), which included 4256 AA adults representing 23,828,268 AA adults nationwide. Chi-squared tests based on weighted data were used to examine differences in CAM users and nonusers.

OUTCOME MEASURES

CAM use was categorized as CAM Ever, CAM Past 12 Months, and CAM for Treatment.

RESULTS

A total of 23,828,268 (weighted) AAs were identified in the NHIS dataset. Of those, 67.6% used CAM in the past 12 months, when prayer for health was included. Users were more likely older (43.3 +/- 0.4 versus 39.5 +/- 0.5 years; p < 0.0001); female (60.9% versus 44.0%; p < 0.0001), college educated (17.4% versus 9.8%; p < 0.0001); and insured (91.0% versus 88.1%; p < 0.0001) compared to nonusers. Prayer was the most common CAM used by more than 60% of respondents, followed by herbals (14.2%) and relaxation (13.6%). A majority utilized CAM to treat illness. The use of CAM was significantly (p < 0.0001) higher across all the disease states common in AAs compared to nonuse.

CONCLUSIONS

A substantial number of AAs use CAM, with use varying across sociodemographic characteristics. Prayer was the most commonly used therapy. Overall, CAM was most often used for the treatment of specific conditions as opposed to prevention, and its use was common among AAs with prevalent disease states. The extent to which CAM served as a complement or an alternative to conventional medical treatment among AAs is unknown and should be investigated.

The use of herbal and other non-vitamin, non-mineral supplements among pre- and post-menopausal women in Ontario

BACKGROUND

Herbal or other non-vitamin, non-mineral (NVNM) supplements are used by many Canadians, and are of public health significance given potential health effects. The majority of supplement users are women, yet there are limited data on their pattern of use. Ontario women were surveyed about their use of NVNM supplements, including those for women's health, and characteristics associated with use were examined.

METHODS

3,423 randomly selected Ontario households were telephoned to identify eligible women (25-65 years). Of the 1,741 identified, 800 agreed to participate and were mailed a self-administered questionnaire querying NVNM supplement use and health-related characteristics. Prevalence of use, duration, and reasons for use were calculated; distributions of respondent characteristics were tabulated and associations with supplement use were assessed.

RESULTS

478 women (27%) completed questionnaires; 64% reported ever, and 34% reported current use of NVNM supplements. Echinacea was the most frequently used, followed by evening primrose, garlic, and camomile; supplements were used for less than one year. Alleviation of symptoms and prevention of illness were two primary reasons for taking NVNM supplements. 49% reported ever, and 37% reported current use of supplements for women's health, and for reasons similar to other NVNM supplements. High body mass index (> or =30.0 kg/m2) was associated with more supplement use, and visiting a physiotherapist in the past year was associated with less.

CONCLUSION

Findings suggest a high level of NVNM supplement use among Ontario women, possibly associated with certain health-related characteristics. This has important public health implications considering possible benefits and/or interactions with conventional medications.

Healthcare seeking and treatment for menopausal symptoms in the United States

OBJECTIVES

A population-based study was used to describe healthcare seeking behavior for menopausal symptoms and treatment among women 40-65 years old in the United States.

METHODS

Participants were recruited into the Menopause Epidemiology Study from the KnowledgePanel(SM), which is selected by random digit dialing and probability sampling from the US population. From this source, 6201 women 40-65 years old were contacted and 4402 women participated. From the 3135 peri- and postmenopausal women, detailed information was obtained on menopausal symptoms, healthcare seeking, medication usage, and symptom relief from the medication.

RESULTS

Many women (60%) reported seeking health care for their menopausal symptoms. More than half of these women sought health care in the past 12 months. Vasomotor symptoms were the most frequently reported menopause symptoms across all races/ethnicities, and the most common symptoms discussed with a health care professional. One-third of the women (34%) used only hormone therapies, 12% used complementary and/or alternative medicines, and 16% used both for treatment of menopausal symptoms.

CONCLUSIONS

This study has shown that a large number of women consult healthcare providers for menopausal symptoms, indicating these symptoms are bothersome. Yet, in the United States, there is considerable variation in the symptomatology, healthcare seeking, and use of therapies for menopausal symptoms across cultures. To alleviate these symptoms women have tried alternative treatments as well as hormone therapies, yet many women did not get complete relief of specific symptoms.

Cross-sectional analysis of specific complementary and alternative medicine (CAM) use by racial/ethnic group and menopausal status: the Study of Women's Health Across the Nation (SWAN)

OBJECTIVE

To examine the relationships of race/ethnicity, menopausal status, health characteristics, and symptoms with use of 21 types of complementary and alternative medicine (CAM) in midlife women.

DESIGN

Cross-sectional, multiple logistic regression analyses of 2,118 women completing the sixth annual visit in the Study of Women's Health Across the Nation, a multisite, multiethnic, longitudinal study.

RESULTS

More than half of women used some type of CAM. Use of most types of CAM differed significantly by race/ethnicity, except the use of ginkgo biloba and glucosamine. Significantly more African Americans at most sites and Chinese women used ginseng. Use of most types of CAM did not differ significantly by menopausal status or vasomotor symptoms, except the use of soy supplements, which was significantly greater among women who reported vasomotor symptoms. Women reporting somatic symptoms were significantly more likely to use glucosamine. Women reporting psychological symptoms were significantly more likely to use ginkgo biloba and soy supplements. The number of comorbidities, moderate or high socioeconomic status, number of healthy behaviors, symptom sensitivity, age, and dietary genistein intake were significantly positively associated with use of several types of CAM.

CONCLUSIONS

The use of most types of CAM is not related to menopausal status or symptom reporting but to sociodemographic factors, comorbidities, and health behaviors. Given the large proportion of midlife women who use CAM and the potential for interactions with prescribed medications, healthcare practitioners should inquire about CAM use and be aware of which factors influence the use of different types of CAM.

Black cohosh with or without St. John's wort for symptom-specific climacteric treatment—Results of a large-scale, controlled, observational study

OBJECTIVES

To evaluate usage pattern, effectiveness and safety of Black cohosh alone or in fixed combination with St. John's wort on menopausal symptoms in general clinical practice.

METHOD

Prospective, controlled open-label observational study of 6141 women at 1287 outpatient gynecologists in Germany. Subjects were treated with recommended doses of study therapies, with treatment chosen by the participating physicians. Patients were followed up for 6 months, optionally 12 months. The primary effectiveness variable was Menopause Rating Scale (MRS) subscore PSYCHE at Month 3 evaluated by ANCOVA.

RESULTS

The treatment groups were comparable at baseline, excepting the main MRS score and the PSYCHE score (monotherapy: 0.31+/-0.22; combination therapy: 0.42+/-0.23). Reductions from baseline were seen with both regimens for all variables. The changes in the primary variable remained significantly different between groups (p<0.001) when adjusted for differences at baseline with the combination therapy being superior: from 0.37 (adjusted) to 0.25 (95% CI: 0.24-0.25) and 0.23 (95% CI: 0.22-0.23) at Month 3 in the monotherapy and combination-therapy groups, respectively. The improvement by both therapies was maintained at 6 and 12 months. The rate of possibly treatment-related adverse events was 0.16%, all non-serious.

CONCLUSION

The results support the effectiveness and tolerability profiles of two Black cohosh-based therapies for menopausal symptoms in general practice. They were used differentially: the monotherapy for neurovegetative symptoms, the combination for patients with more pronounced mood complaints. The fixed combination of Black cohosh and St. John's wort was superior to Black cohosh alone in alleviating climacteric mood symptoms.

Health locus of control and use of conventional and alternative care: a cohort study

BACKGROUND

Health locus of control influences health-related behaviour, but its association with healthcare use is unclear.

AIM

To investigate the association between individuals' health locus of control and the use of conventional and alternative health care.

DESIGN OF STUDY

Prospective cohort study.

SETTING

A nationally representative random sample of community-dwelling adult households in Japan.

METHOD

Health locus of control, symptom-related visits to physicians, and the use of dietary and physical complementary and alternative medicine (CAM) was measured. Dietary CAM included supplements, such as herbs and vitamins. Physical CAM included manipulations, such as acupuncture and acupressure.

RESULTS

Of the 2453 adult participants studied, 2103 (86%; 95% CI [confidence interval] = 84 to 88%) developed at least one symptom during the 31-day study period. Of these symptomatic adults, 639 visited physicians (30%; 95% CI = 28 to 32%), 480 used dietary CAM (23%; 95% CI = 21 to 25%), and 156 (7%; 95% CI = 6 to 9%) used physical CAM. The likelihood of visiting a physician was not related significantly to individuals' health locus of control. Increased use of dietary CAM was weakly associated with control by spiritual powers (P = 0.028), internal control (P = 0.013), and less control by professionals (P = 0.020). Increased use of physical CAM was significantly associated with control by spiritual powers (P = 0.009) indicating a belief that supernatural forces control individuals' health status.

CONCLUSION

The likelihood of visiting a physician is not affected by individuals' health locus of control. Control by spiritual powers is involved with increased CAM use. Internal control is weakly associated with greater use of dietary CAM; professional control is weakly associated with less use of dietary CAM.

Complementary and alternative medicine use among American women: findings from The National Health Interview Survey, 2002

BACKGROUND

The prevalence of use of complementary and alternative medicine (CAM) among Americans is high, especially among women, but a national profile of women CAM users has yet to be characterized. This study identified sociodemographic, health, and lifestyle factors associated with use of various types of CAM among women in the United States and examined health conditions and reasons for use.

METHODS

Data from the 2002 National Health Interview Survey (NHIS), a nationally representative sample of U.S. adults, were analyzed (n = 17,295 women). Any recent use of CAM as well as specific types of CAM (e.g., biologically based therapies) use were analyzed; prayer was considered separately. Prevalence estimates and logistic regression results were weighted, and variance estimates were adjusted for complex sample design.

RESULTS

About 40% of women reported any recent CAM use. Biologically based therapies (23.8%) were the most frequently reported CAM type, followed by mind-body therapies (20.9%). User characteristics were generally similar across specific CAM types; there were some differences between women who used CAM and women who prayed for health. Women frequently reported using CAM in conjunction with conventional medicine and to treat chronic pain conditions.

CONCLUSIONS

This study provides a comprehensive profile of recent CAM use among a national sample of American women, including user characteristics and reasons and conditions for use. Widespread CAM use reflects a social phenomenon of healthcare-seeking practices that can potentially inform public health strategies for health promotion and disease prevention.

Use of complementary and alternative therapies by Asian Americans. Results from the National Health Interview Survey

Very little is known about complementary and alternative medicine (CAM) use in Asian Americans (AA), especially on a national level. To compare CAM use, reasons for use, and disclosure rates between Asian and non-Hispanic white Americans (NHW), and examine ethnic variations among AA. Data on CAM use in the past year (excluding prayer) were used from the 2002 National Health Interview Survey for 917 AA and 20,442 NHW. Compared with NHW, AA were as likely to use any CAM modality [42 vs. 38%; adjusted prevalence ratio = 1.09, 95% confidence interval (0.94, 1.27)]. Asian Americans were less likely than NHW to disclose the use of herbal medicines (16 vs. 34%, p < 0.001) and mind/body therapies (15 vs. 25%, p < 0.05). Mind/body therapies were used more often by Asian Indians (31%) than by Chinese (21%) and Filipinos (22%), whereas herbal medicines were used more often by Chinese (32%) than by Filipinos (26%) and Asian Indians (19%). Among AA, CAM use was associated with being female, having higher education, and having a chronic medical condition; foreign-birth was not associated with CAM use. Complementary and alternative medicine use is common among AA, and there are important ethnic variations in use. Asian Americans are less likely than NHW to disclose CAM use to conventional healthcare providers, suggesting that it is particularly important that physicians query AA patients about CAM use.

The complementarity and substitution between unconventional and mainstream medicine among racial and ethnic groups in the United States

OBJECTIVES

To describe racial and ethnic differences in the utilization patterns of 12 common types of complementary and alternative medicine (CAM) and mainstream medicine (MSM) and to test whether a specific CAM type is a substitute for or a complement to MSM among five racial and ethnic groups in the United States.

METHODS

The Medical Expenditure Panel Survey in 1996 and 1998 were used. The sample of 46,673 respondents was stratified into non-Hispanic whites (NHW), Hispanics, blacks, Asians, and other races. Twelve types of CAM visits and visits to office-based and outpatient physicians were used to describe the pattern of CAM and MSM use. Utilization patterns among each racial and ethnic group were established and compared. Multivariate analyses were conducted to test whether each type of CAM and MSM were complements or substitutes within a racial and ethnic group, controlling for respondents' sociodemographics and health.

RESULTS

Significant intergroup differences in the prevalence rates of using various types of CAM were found. In particular, for some racial and ethnic groups, CAM can be either a substitute for or a complement to MSM visits, depending on the CAM type. More complementary relationships between CAM and physician visits were found in NHW and Asians than in other groups. All significant relationships between CAM types and physician visits among Hispanics and other races (predominantly Native American Indians) were substitution.

CONCLUSIONS

Complementarity and substitution of CAM and MSM varied by racial and ethnic groups and by type of CAM. Culturally sensitive approaches are needed in successful integration of CAM in treatment management.

Women's health during mid-life survey

OBJECTIVE

To survey the extent of complementary and alternative medicine (CAM) use among women for the alleviation of menopausal symptoms.

DESIGN

A total of 1,296 eligible women aged 45 to 65 years were recruited from three Sydney menopause clinics, general practice clinics, and government agencies between July 2003 and July 2004. Volunteers were invited to complete a 19-item questionnaire covering basic demographics, general health status, use of CAM therapies and products, use of pharmaceuticals, and sources of CAM advice.

RESULTS

Of respondents, 53.8% had visited a CAM practitioner and/or used a CAM product during the past year, with 34% using a product only and 5% consulting a practitioner only. The most commonly visited practitioners were naturopaths (7.2%) and acupuncturists (4.8%), whereas the most popular products were soy (25.4%) and evening primrose oil (18.4%). Massage, chiropractic, and nutrition were rated the most effective therapies, and phytoestrogen tablets, evening primrose oil, and black cohosh were deemed the most effective products. Of the 59.9% of respondents currently using prescription or over-the-counter pharmaceuticals, 62.5% reported using CAM products during the past 12 months. Of CAM users 71% had informed their doctor about CAM use, whereas 26.4% of respondents reported their doctor had inquired about CAM use.

CONCLUSIONS

CAM use by women to alleviate menopausal symptoms is common, with several therapies perceived to be effective. Although a significant proportion of women may use CAM in conjunction with pharmaceuticals, relevant communication between medical practitioners and patients remains inadequate and may expose the patient to potential drug-herb interactions.

Complementary and alternative medicine use among Asian-American subgroups: prevalence, predictors, and lack of relationship to acculturation and access to conventional health care

OBJECTIVES

Acculturation and access to conventional health care have been found to be predictors of complementary and alternative medicine (CAM) use in the general population. We hypothesized that these factors would be predictors of CAM use in Asian-American subgroups. Because of differences in health and cultural beliefs, we also hypothesized that patterns and predictors of CAM use would vary among Asian-American subgroups.

METHODS

Cross-sectional survey of a sample of 9187 adults representative of the California population.

RESULTS

Nearly three quarters of Asian-Americans used at least one type of CAM in the past 12 months, which was significantly higher than the national prevalence rate. Chinese Americans had the highest prevalence of any CAM use, whereas South Asians had the lowest prevalence (86% vs. 67%, respectively). Acculturation and access to conventional medical care was unrelated to any CAM use for most Asian-American subgroups. Spirituality was the strongest predictor of any CAM use for most Asian-American subgroups.

CONCLUSIONS

CAM use varies across Asian-American subgroups. Acculturation and access to conventional medical care is unrelated to any CAM use for most Asian-American subgroups.

Complementary and alternative medicine use among midlife women for reasons including menopause in the United States

OBJECTIVE

The use of complementary and alternative medicine (CAM) has been examined previously for midlife women only in regional studies. The purpose of this study was to obtain national estimates of CAM use.

DESIGN

Data were obtained from the 2002 National Health Interview Survey, which included a CAM supplementary questionnaire. The response rate was 74%. The analysis included 3,621 female respondents between 45 and 57 years of age who had answered all of the relevant questions. SUDAAN software was used to account for the complex sampling design.

RESULTS

Forty-five percent of women 45 to 57 years of age had used some form of CAM within the last 12 months. Approximately 25% used biologics (e.g., herbs) or mind-body (e.g., biofeedback) modalities, whereas only 15% used body work (massage and chiropractic medicine). Use did not vary by age, but white race, higher education, and residence in the West were associated with increased use. Only 45% of CAM users mentioned its use to a medical provider. The most cited reason for using CAM involved treatment of pain, with only 3% mentioning menopause. However, the odds for use of CAM were almost twice as high for women with menopausal symptoms in the past year compared with women with no symptoms (odds ratio: 1.9, 95% CI: 1.6-2.2).

CONCLUSIONS

CAM use among midlife U.S. women is high, although CAM is not used specifically for menopausal concerns. These data will be useful as a benchmark of the use of CAM as use of conventional menopause therapies are influenced by the Women's Health Initiative results.

Factors associated with the use of complementary medicine and non-pharmacological interventions in symptomatic menopausal women

BACKGROUND

Hormone replacement therapy is now thought to have serious adverse effects; consequently, many menopausal women are seeking to use complementary and alternative medicine (CAM), including non-pharmacological interventions (NPI), to alleviate symptoms. The prevalence and perceived effectiveness of CAM and NPI for ameliorating menopausal symptoms are not widely known and factors likely to predict CAM and NPI utilization for menopausal symptom management have not been comprehensively documented.

OBJECTIVES

The objectives of this study were to (1) determine the prevalence of using CAM and NPI for menopausal symptoms; (2) describe the perceived effectiveness of CAM and NPI for symptom management; and (3) investigate lifestyle and demographic factors associated with CAM/NPI use among menopausal women with vasomotor symptoms.

METHODS

Women aged 46-55 years were recruited via six socioeconomically diverse general practices. Participants completed a postal questionnaire that contained items relating to demographics, lifestyle factors, weight, height, exercise behavior, menopausal status, vasomotor symptoms and utilization and perceived effectiveness of a range of CAM/NPI for symptom management.

RESULTS

Of 1,206 women who responded, 563 (47%) were symptomatic. The most commonly used CAM/NPI for symptom management were diet/nutrition (44.3%), exercise/yoga (41.5%), relaxation/stress management (27.4%) and homeopathic/naturopathic remedies (25.4%). Of women who used these interventions, large proportions reported them to be helpful. The characteristics that were independently associated with use of CAM/NPI were White ethnicity, being physically active, and not smoking.

CONCLUSIONS

Many menopausal symptomatic women are using a wide range of CAM/NPI and report these to be effective, particularly those who are white, physically active and do not smoke.

Sertraline to treat hot flashes

OBJECTIVE

To evaluate the effectiveness of a selective serotonin reuptake inhibitor (SSRI) (sertraline) in decreasing hot flashes in a general population of women.

DESIGN

A double-blind, placebo-controlled, crossover trial was conducted in a southwestern urban setting. A total of 102 women aged 40 to 65 who were experiencing hot flashes and not taking any hormone therapy were recruited. After 1 week of baseline hot flash data collection, study participants were randomized to receive placebo or active drug (sertraline 50 mg) for 4 weeks. This intervention was followed by a 1-week washout and cross over to the opposite treatment for 4 weeks. The number and severity of hot flashes were measured.

RESULTS

One hundred two women were enrolled in the study. Five dropped out before providing baseline data. Of the 97 remaining, 52 were randomized to active drug first and 45 to placebo first. Ten dropped out of the study before completing all 10 weeks, leaving 46 in the active drug-first arm and 41 in the placebo-first arm. At baseline, the mean number of hot flashes reported was 45.6 per week (SD = 29.6), ranging from 2 to 148. During the sertraline phase of the study, women experienced five fewer hot flashes per week than they did on the placebo (P = 0.002). The severity of hot flashes was not significantly different; however, the hot flash score (number x average severity) was significantly improved during the sertraline phase.

CONCLUSION

Sertraline reduced the number of hot flashes and improved the hot flash score relative to placebo and may be an acceptable alternative treatment for women experiencing hot flashes.

Use of Herbal/Natural Supplements According to Racial/Ethnic Group

OBJECTIVES

The aim of this paper was to determine similarities and differences in the use of herbal/natural supplements among various racial/ethnic groups.

DESIGN

A random-digit dial (RDD) telephone survey of medication use during the week before the interview was used.

SETTINGS/LOCATION

Households in the 48 contiguous United States comprised our study.

SUBJECTS

One (1) subject was selected by a random procedure from each contacted household, including interviews conducted from 1998 through September 2004. There were 13,436 subjects at least 18 years of age, including 10,372 non-Hispanic whites, 1174 African Americans, 1109 Hispanics, 335 Asian/Pacific Islanders, and 446 others.

OUTCOME MEASURES

Use of any herbal/natural product during the prior week served as outcome measures. Prevalence of use was weighted according to household size; for comparisons among the three largest groups, estimates were also adjusted for age, gender, and education.

RESULTS

The overall prevalence was lowest in African Americans (9.5%; 95% confidence interval [CI], 7.8%-11%), intermediate in Hispanics (12%; 10%-14%), and highest in non-Hispanic whites (19%; 18%-20%). Use was higher among women and generally higher for subjects 45-64 years of age, regardless of race/ethnicity; use increased with increasing years of education. The most commonly taken individual herbal/natural substances were similar among the groups. Hispanics used the largest number of products. Distribution of product type differed somewhat, with Hispanics taking more monopreparations and herbal mixtures than the other groups, and herbal mixture use particularly uncommon among African Americans. Use between 1998 and 2004 increased slightly for non-Hispanic whites, increased then declined for African Americans, and did not change for Hispanics.

CONCLUSIONS

Based on nationally representative U.S. data, these results provide a comparative picture of contemporary use of herbal/natural supplements in the largest racial/ethnic groups in the United States. The prevalence of use was lowest among African Americans, with a possible decline in recent years, whereas Hispanics take the greatest number of products.

Race/ethnicity and women's use of complementary and alternative medicine in the United States: results of a national survey

OBJECTIVES

We studied the use of complementary and alternative medicine (CAM) among women in 4 racial/ethnic groups: non-Hispanic Whites, African Americans, Mexican Americans, and Chinese Americans.

METHODS

We obtained a nationally representative sample of women aged 18 years and older living in the United States in 2001. Oversampling obtained 800 interviews in each group, resulting in a sample of 3068 women.

RESULTS

Between one third and one half of the members of all groups reported using at least 1 CAM modality in the year preceding the survey. In bivariate analyses, overall CAM use among Whites surpassed that of other groups; however, when CAM use was adjusted for socioeconomic factors, use by Whites and Mexican Americans were equivalent. Despite the socioeconomic disadvantage of African American women, socioeconomic factors did not account for differences in CAM use between Whites and African Americans.

CONCLUSIONS

CAM use among racial/ethnic groups is complex and nuanced. Patterns of CAM use domains differ among groups, and multivariate models of CAM use indicate that ethnicity plays an independent role in the use of CAM modalities, the use of CAM practitioners, and the health problems for which CAM is used.

Associations between the use of complementary and alternative medications and demographic, health and lifestyle factors in mid-life Australian women

OBJECTIVE

To determine the prevalence and types of complementary and alternative medications (CAMs) used by menopausal women living in South-East Queensland, Australia; and profile the women who are using CAMs through sociodemographic characteristics, self-rated health status, lifestyle and preventative health strategies.

METHOD

This study was a secondary data analysis of data collected by postal questionnaire from 886 women aged 48-67 years participating in the Queensland Midlife Women's Health Study. The outcome measure was CAM use, distinguished by three categories: herbal therapies, phytoestrogens and nutritional intake (supplements and healthy eating).

RESULTS

The overall prevalence of CAM use among mid-life Australian women was 82% which included therapeutic techniques (83%), nutritional supplements (66.8%), phytoestrogens (55.8%), herbal therapies (41.3%), Evening Primrose oil (34%) and vitamin E (28.8%). CAM users, when compared to non-users, were more likely to be previous (p < 0.05) but not current users (p < 0.05) of hormone therapy (HT), higher educated (p < 0.05), low to middle income earners (p < 0.001) and have participated in self-breast examination (p < 0.01). They were also more likely to report good general health (p < 0.05) and improved physical functioning without limitations due to health (p < 0.05). CAM users were less likely to be aged over 55 years (p < 0.05) and smoke more than 20 cigarettes per day (p < 0.001). CONCLUSIONS/IMPLICATIONS FOR HEALTH RESEARCH: As prevalence of current CAM use in this population group is considerably higher than HT use, health education programs to assist mid-life women to understand the scientific evidence (or lack of it) for their efficacy is recommended.

Complementary and alternative medical therapy use among Chinese and Vietnamese Americans: prevalence, associated factors, and effects of patient-clinician communication

OBJECTIVE

We examined the use of complementary and alternative medical (CAM) therapies among Chinese and Vietnamese Americans who had limited proficiency with the English language and explore the association between patient-clinician discussions about CAM therapy use and patient assessments of quality of care.

METHODS

We surveyed Chinese and Vietnamese Americans who visited 11 community health centers in 8 major cities throughout the United States.

RESULTS

Of the 4410 patients surveyed, 3258 (74%) returned completed questionnaires. Two thirds of respondents reported they had "ever used" some form of CAM therapy; however, only 7.6% of these patients had discussed their use of CAM therapies with clinicians. Among patients who had used CAM therapies during the week before their most recent visits, clinician-patient discussions about CAM therapy use were associated with better overall patient ratings of quality of care.

CONCLUSION

Use of CAM therapies was common among Chinese and Vietnamese Americans who had limited proficiency with the English language. Although discussions about CAM therapy use with clinicians were uncommon, these discussions were associated with better ratings of quality of care.

Symptoms during the perimenopause: prevalence, severity, trajectory, and significance in women's lives

This article examines published evidence from longitudinal studies of the menopausal transition that address the following questions: (1) Which symptoms do women report during the perimenopause, and how prevalent are these symptoms as women traverse the menopausal transition? (2) How severe are symptoms and for how long do they persist? (3) To what do women attribute their symptoms, and do their attributions match findings from epidemiologic studies of community-based populations? (4) How significant are these symptoms in women's lives? Data from published longitudinal studies were examined for evidence bearing on each of these questions. Only vasomotor symptoms, vaginal dryness, and sleep disturbance symptoms varied in prevalence significantly across menopausal transition stages and postmenopause in >1 population studied. A minority of women report severe symptoms. Given the limited follow-up data available, it is unclear how long symptoms persist after menopause. Women attribute their symptoms to a variety of biologic and psychosocial factors, and their attributions correspond well to those correlates identified in epidemiologic studies of community-based populations. The significance of symptoms for women's lives remains uncertain. The impact of symptoms during the perimenopause on well-being, role performance, adaptation to demands of daily living, and quality of life warrants additional study. The appraisal of the consequences of perimenopausal symptoms by women from different ethnic groups will be enhanced significantly as a result of the Study of Women's Health Across the Nation (SWAN) and other studies in progress.

The conundrum of increased burden of end-stage renal disease in Asians

BACKGROUND

Few cohort studies have examined the risk of end-stage renal disease (ESRD) among Asians compared with whites and blacks.

METHODS

To compare the incidence of ESRD in Asians, whites, and blacks in Northern California, we examined sociodemographic and clinical data on 299,168 adults who underwent a screening health checkup at Kaiser Permanente between 1964 and 1985. Incident cases of ESRD were ascertained by matching patient identifiers with the nationally comprehensive United States Renal Data System ESRD registry.

RESULTS

Overall, 1346 cases of ESRD occurred during 7,837,310 person-years of follow-up. The age-adjusted rate of ESRD (per 100,000 person-years) was 14.0 [95% confidence interval (CI) 10.5-18.5] among Asians, 7.9 (95% CI 6.5-9.5) among whites, and 43.4 (95% CI 36.6-51.4)] among blacks. Controlling for age, gender, educational attainment, diabetes, prior myocardial infarction, serum creatinine, systolic and diastolic blood pressure, proteinuria, hematuria, cigarette smoking, serum total cholesterol, and body mass index increased the risk of ESRD in Asians relative to whites from 1.69 to 2.08 (95% CI 1.61-2.67). By contrast, adjustment for the same covariates decreased the risk of ESRD in blacks relative to whites from 5.30 to 3.28 (95% CI 2.91-3.69).

CONCLUSION

Factors contributing to the excess ESRD risk in Asians relative to whites extend beyond usually considered sociodemographic and comorbidity disparities. Strategies aimed at examining novel risk factors for kidney disease and efforts to increase awareness of kidney disease among Asians may reduce ESRD incidence in this high-risk group.

Herb and supplement use in the US adult population

BACKGROUND

Research on the scope of use and factors associated with herbal medicine use is limited.

OBJECTIVES

The aims of this work were to assess national usage patterns, reasons for use, and the perceived efficacy of herbal products and dietary supplements.

METHODS

This was a secondary analysis of the complementary and alternative medicine (CAM) supplement to the 2002 National Health Interview Survey (NHIS), conducted by the National Center for Health Statistics (NCHS). Participants were asked whether they had used natural herbs for their own health and treatment. Those who responded yes were compared with those who responded no. Supplement users were asked whether they had used any of 36 specific herbs or nonherbal dietary supplements (eg, glucosamine, fish oil, bee pollen), how important the use of CAM treatment was to them, whether they had seen a CAM provider, and whether they had informed a conventional medical provider about their use. NCHS weights, derived from Decennial Census data, were used to calculate national prevalence estimates. Group comparisons of herbal use were conducted with the Wald x(2) test.

RESULTS

A total of 31,044 adults participated in the 2002 NHIS CAM survey; 632 were omitted from analyses due to incomplete information. In all, 5787 adults said they had used herbs or supplements during the previous 12 months, of whom 57.3% said they used these products to treat specific conditions. Based on these responses, an estimated approximately 38.2 million adults in the United States used herbs and supplements in 2002. More than half of all users said that herbs and natural products were important to their health and well-being. Use rates were higher for women than men (21.0% vs 16.7%; P < 0.001); adults aged 45 to 64 years (P < 0.001 vs other age groups); those of multiple races (32.2%), Asians (24.6%), or American Indians or Alaskan natives (21.9%) rather than whites (19.1%) or blacks (14.3%) (effect of race, P < 0.001); residents of the western United States (effect of region, P < 0.001), and college graduates (25.3% vs 10.4% among those who did not graduate high school; effect of education, P < 0.001). Only 33.4% told a conventional health care provider about their herb or supplement use use.

CONCLUSION

Herb and natural supplement use was widespread in the US adult population in 2002, according to data from the NHIS CAM survey, despite the fact that few participants informed their conventional health care providers about such use.

Age, race, and ethnicity in the use of complementary and alternative medicine for health self-management: evidence from the 2002 National Health Interview Survey

OBJECTIVES

Determine if complementary and alternative medicine (CAM) use for treating existing conditions and for health maintenance differs by age and ethnicity.

METHODS

Data from the 2002 National Health Interview Survey were used to operationalize distinct types of CAM in terms of (a) no use, (b) use for treatment only, (c) use for prevention only, and (d) use for both treatment and prevention. Differences in CAM use by age and ethnicity were examined using SUDAAN to adjust for design effects.

RESULTS

Associations of age with CAM use are curvilinear but differed by ethnicity. Some types of CAM are used primarily for treatment; others are used for health maintenance.

DISCUSSION

CAM use is one component of adults' overall approach to health self-management. Patterns of CAM use by age and ethnicity likely reflect differences in CAM availability and prevailing public health policies when adults began making their own health-related decisions.

A longitudinal analysis of mid-age women's use of complementary and alternative medicine (CAM) in Australia, 1996-1998

Complementary and Alternative Medicine (CAM) has become increasingly popular amongst healthcare consumers world-wide. As such, CAM is now an important public health issue with taking non-prescription medications. This paper constitutes an exploratory investigation into CAM use over time. As such, there is need for further research to provide in-depth examination of the adoption and relinquishment of CAM use over a longer time period. serious implications for healthcare organization and delivery. While previous studies have provided a profile of CAM users, there remains very limited analysis of CAM consumption over time. The purpose of this paper is to describe the changing use of CAM practitioners over time by 11,454 mid-age women in the Australian Longitudinal Study on Women's Health. Over the study period (1996-1998), 10% of women adopted the use of CAM and 9% relinquished CAM. The predominant factor found to be predictive of CAM adoption was changes in health status. Specifically, those women experiencing more illness over time are more likely to adopt CAM than those experiencing no change or better health. CAM relinquishment was associated with use of non-prescription medications, where women were more likely to relinquish CAM if they never used non-prescription medications or if they stopped.

Menopausal Symptom Management and Prevention Counseling after the Women's Health Initiative among Women Seen in an Internal Medicine Practice

OBJECTIVE

To describe the management of menopausal symptoms and the prevalence of prevention counseling among women who stopped hormone therapy (HT) after publication of the initial findings of the Women's Health Initiative.

METHODS

Telephone survey between July and September 2003 of 142 women 50 years and older, randomly selected from a large academic primary care practice, who stopped taking HT after the WHI publication, July 9, 2002 (66% response rate).

RESULTS

Among 142 women, the median age was 60 years, 63% were white, 52% had at least a college degree, and 60% were taking estrogen and progestin as of July 9, 2002. The majority (82%, n = 117) who stopped HT suffered some menopausal symptom: 25 restarted HT, 13 received another prescription medication, and 56 tried at least one complementary and alternative medicine. Women most commonly used soy (n = 40) or black cohosh (n = 25) for their symptoms, although less than one third of women found either of these treatments effective. Only 49% (57 of 117) of women with symptoms visited a doctor for their symptom. Few women reported receiving counseling about prevention topics after the WHI, such as risk of osteoporosis (34%), risk of heart disease (26%), diet (41%), and exercise (45%).

CONCLUSIONS

Most women who stopped HT after the WHI experienced some menopausal symptoms. Few women found commonly used alternative medicines effective, and few received other prescription medications. Counseling about osteoporosis and heart disease risk was infrequent after the WHI. Future studies should focus on finding safe and effective therapies for menopausal symptoms.

Menopause, micronutrients, and hormone therapy

Micronutrient and herbal/phytochemical supplements are of increasing interest as potential alternatives to using estrogen therapy in treating menopausal symptoms. This article provides an overview of the questionnaires that assess menopausal symptoms and research efforts to better standardize symptom assessment. The reported rate of symptoms varies by ethnicity, stage of menopause, hormonal therapy and the measurement method. The use of estrogen therapy has declined sharply after the Women's Health Initiative (WHI) Hormone Trial was stopped early because the potential risks outweighed potential benefits. There is a limited research base that addresses the efficacy of supplements in controlling menopausal symptoms. The generalizability of several studies is limited because the study participants experiences menopause as the results of treatment for breast cancer. The article concludes with a review of guidelines and of issues that need to be addressed in future research studies with emphasis on questions related to clinical practice.

[Persistence of a magic-religious ritual to treat indigestion among patients attending a gastroenterology outpatient clinic]

INTRODUCTION

Knowledge of popular medicine is essential to the practice of integrated medicine. Empacho (stomach upset) is a known folk illness that has been the object of several studies, especially in Iberoamerica and among the Hispanic population in the United States. In the Autonomous Community of Valencia (Spain) a magic-religious ritual known as "trencar lenfit" (TE) is still performed. This ritual has no apparent equivalent among the numerous remedies described for this illness.

OBJECTIVES

To study the frequency and characteristics of the practice of TE among patients attending the gastroenterology outpatient clinic of a district hospital.

PATIENTS AND METHOD

The geographical area was the region of La Safor (Valencian Community) with three main nuclei (Gandia, where the hospital is situated, Oliva and Tavernes de Valldigna) and 28 smaller municipalities. Random interviews were performed in patients attending a second consultation over a period of 5 months.

RESULTS

Of 539 patients interviewed, 320 (59.4%) had undergone TE at some time in their lives and 25.0% had undergone this ritual in the previous 10 years. In 95.9% of cases, the person performing the ritual was a woman. Of the patients who had undergone TE, 40 (12.5%) knew how to perform the ritual, 35 of which were women (p < 0.0001). No significant differences were found between sexes but users were younger (51.8 +/- 15.9 versus. 55.5 +/- 17.7 years +/- SD, p < 0.05). Small municipalities and Oliva showed a frequency of 65.6% versus. 54.0% in Gandia and Tavernes (p < 0.005). Use was greater among natives of the Valencian Community (66.0%) compared with those from other parts of Spain (25.0%) (p < 0.0001). Patients who completed primary or secondary school showed greater use of TE (60.5% and 72.1%, respectively) than the illiterate (42.1%), those who had completed a 3-year higher education course (48.4%) and university graduates (36.0%) (p < 0.001). TE was more frequent among consumers of medicinal herbs than among non-consumers (69.0% versus. 54.3%) (p < 0.001). No relationship was found among TE and the use of alcohol, medication in general and smoking. However, an association was found between the use of psychotropic drugs (69.8% versus. 55.4%) (p < 0.005). No clear association was found with broad diagnostic group or with the functional/organic nature of the digestive disorder studied. Variables found to be significant on univariate analysis remained significant in multivariate analysis (logistic regression).

CONCLUSION

The present study confirms the high use of TE among patients attending the gastroenterology outpatient clinic of La Safor and their belief in this ritual. "Experts" in performing TE were widely available, and were almost exclusively women. The profile of maximal use of TE corresponds to a man or woman, aged less than 60 years, a native of the Valencian Community, with primary or secondary school education, residing in particular municipalities (usually small) and consumer of psychotropic drugs and medicinal herbs.

Use of complementary and alternative medicine among American women

INTRODUCTION AND BACKGROUND

Although women are increasingly using complementary and alternative (CAM) therapies, a national profile characterizing women who use CAM has yet to be described. The purpose of this study is to provide prevalence estimates of recent CAM use among American women and to examine sociodemographic and other characteristics associated with use.

METHODS

Data from the 1999 National Health Interview Survey are used for the analysis. Three operational definitions of recent CAM use are employed (any CAM, type-specific, and domain-specific use). All proportions and prevalence estimates are weighted and standard errors are adjusted to account for complex sample design; weighted logistic regression (with coefficient variance adjustment) is also used.

RESULTS

Overall, 33.5% of American women used CAM in the past 12 months. Spiritual healing/prayer and herbal medicine are the most commonly used, and hypnosis, biofeedback, and energy healing are the least common. Multivariate results show that women who are older, have more education, poorer health, or live in the west or midwest (versus south) are more likely to use CAM. Compared to whites, blacks, Hispanics, and Asians are less likely to use CAM. Foreign-born women, those with lower income, or who live in the Northeast are also less likely to use CAM. Insurance status is not independently associated with CAM use.

CONCLUSIONS AND DISCUSSION

This study provides one of the first comprehensive investigations of CAM use among American women. Future research examining the determinants of CAM use, incorporating attitudinal and health conditions, as well as clinical efficacy, effectiveness, and health outcome studies of specific CAM therapies are warranted.
