Women's use of herbal and alternative medicines for preconception care.

BACKGROUND: Use of complementary and alternative medicine (CAM), particularly herbal and alternative medicine supplements, for preconception care and fertility management is becoming increasingly common. AIMS: To determine the factors associated with the use of CAMs by women for preconception care. MATERIALS AND METHODS: 412 women who had visited an antenatal 'first visit' clinic situated at a Brisbane obstetric hospital or had visited a private ultrasound clinic in the same city for the purposes of a routinely indicated ultrasound scan in the first trimester were recruited into the study. Data were collected via a cross-sectional questionnaire. RESULTS: Complementary and alternative medicines (not including multivitamins) were used during preconception by 8.3% of women attending for obstetric care. Approximately half (55.8%) of women taking herbal and alternative medicines ceased these medications on discovery of their pregnancy, though fewer (17.4%) ceased taking multivitamin supplements. Baseline characteristics (age, education and income) are not significantly different between CAM users and those who did not take CAMs preconception. The results of statistical analyses showed that only visiting a practitioner to check for health (OR = 2.00; 95% CI: 1.33, 3.00) and trying to lose weight prior to pregnancy (OR = 1.53; 95% CI: 1.00, 2.36) were the key predictors for women using CAM during preconception. CONCLUSIONS: Women do consume CAMs to enhance preconception care to a certain extent, though CAM users remain in the minority. CAM users also tend to cease use once pregnant.

Public awareness, patterns of use and attitudes toward natural health products in Kuwait: a cross-sectional survey.

BACKGROUND: There has been a global rise in the use of natural health products (NHPs). Proper regulation of NHPs is pivotal to ensure good quality control standards, enhance consumers' safety and facilitate their integration into modern healthcare systems. There is scarcity of published data on the prevalence of NHPs usage among the general Kuwaiti population. Hence, this study was designed to determine awareness, patterns of use, general attitude and information requirements about NHPs among the public in Kuwait. METHODS: A descriptive cross-sectional survey was performed using a pretested self-administered questionnaire on a sample of 1300 Kuwaiti individuals, selected from six governorates in Kuwait using a multistage stratified clustered sampling. Descriptive and multivariate logistic regression analysis were used in data analysis. RESULTS: The response rate was 90.2%. NHPs were thought to be herbal remedies by most of participants (63.5%), followed by vitamins/minerals (40.5%), traditional medicines (21.1%), probiotics (14.9%), amino acids and essential fatty acids (7.2%), and homeopathic medicines (5.6%). NHPs usage was reported by 71.4% (95% CI: 68.8-74.0%) of respondents, and mostly associated with females (OR: 1.90; 95% CI: 1.44-2.51). Herbal remedies were the most commonly used (41.3%; 95% CI: 38.5-44.2%). The most common reasons for using NHPs were to promote and maintain health and to prevent illness and build immune system. Family members and/or friends and mass media were the main sources for providing information about NHPs. About 18% of consumers have experienced a side effect due to using a NHP. Attitudes toward NHPs were generally positive; with more than 75% of participants believing that the Ministry of Health in Kuwait should regulate the claims made by the manufacturers of NHPs and it is important to talk to a medical doctor or a pharmacist prior to using NHPs. Most of the respondents showed increased interest to acquire knowledge about different types of information related to NHPs. CONCLUSIONS: The prevalence of use of NHPs among Kuwaiti population is high. The present findings have major public health policy implications for Kuwait. Therefore, there is an apparent need to establish effective health education programs and implement better and more regulated NHPs use policies in Kuwait.

Use of natural health products in children: survey of parents in waiting rooms.

OBJECTIVE: To determine how common it is for parents to give natural health products (NHPs) to their children, which NHPs are being used, why they are being used, and parents' assessments of the benefits and side effects of NHPs. DESIGN: Survey. SETTING: Newfoundland and Labrador. PARTICIPANTS: Parents waiting in their family doctors' offices. MAIN OUTCOME MEASURES: Parent and child demographic characteristics; pediatric chronic medical conditions affecting the children; prescribed medications, over-the-counter medications, and NHPs used by the children; why the medications and NHPs were being used, the dose, and parents' assessments of the effectiveness and side effects; and where parents had heard about the NHPs, whether they had told their physicians that the children were taking the products, and where they had obtained the products. RESULTS: A total of 202 (53.4%) of the 378 eligible adults who were approached completed the survey. This represented 333 children. Mean (SD) age of the children was 5.1 (3.3) years. Overall, 28.7% of parents reported using nonvitamin NHPs for their children. A total of 137 children (41.1%) had taken NHPs (including vitamins); 61.1% of the NHPs being used were vitamins. The remainder fell under teas (primarily chamomile and green teas), echinacea, fish or omega-3 oils, and a large category of "other" products. These NHPs were most commonly used to improve general health, improve immunity, and prevent colds and infections. Approximately half of the parents (51.7%) believed their children had benefited from taking NHPs, and 4.4% believed their children had experienced adverse side effects. Slightly less than half of the parents (45.0%) had informed their physicians that their children were taking NHPs. CONCLUSION: Overall, 45.5% of parents attending physicians' offices reported using NHPs in their children. If vitamins are not included in the definition of NHPs, this rate drops to 28.7%. Parents most commonly use NHPs to maintain the general health of their children, to prevent colds, and to boost children's immune systems. About half of the parents believed the NHPs helped, very few had noticed any side effects, and approximately half had informed their physicians that they were giving their children NHPs.

Complementary and alternative medicines use by Scottish women with breast cancer. What, why and the potential for drug interactions?

BACKGROUND: Despite the increased use of complementary and alternative medicine (CAM) by breast cancer patients, there is little published information regarding CAM use in the Scottish breast cancer population. METHODS: A questionnaire comprising five sections--demographics; perceived health status, prescribed medicines; use, indications, satisfaction and expenditure on CAMs; attitudes towards and factors associated with CAM use; and attitudinal statements--was issued to patients attending the Aberdeen Breast Clinic. RESULTS: A total of 453 questionnaires were distributed and 360 (79.5%) returned. Respondents were prescribed a mean of 3.2 medicines (95% CI 2.83-3.47). With regard to CAM use, 33.1% of respondents reported current use, 36.4% prior use, and 30.6% reported never having used CAMs. The key indications for use were general well being, boosting immune system and cancer prophylaxis, with high levels of satisfaction reported. The strongest association for CAM use was use by friends and family and higher educational attainment (p < 0.001). Supplements with estrogenic activity, such as soya or red clover, were taken by 29% of respondents. Herbs (echinacea, pomegranate, peppermint, chamomile, grapefruit, garlic, ginseng) that have the potential to interact with adjuvant endocrine therapies (tamoxifen, anastrazole, letrozole, exemestane) were being taken by 38% of treated patients. CONCLUSION: The level of CAM use by Scottish breast cancer patients is similar to that reported from other countries, although there are marked differences in the type, nature and frequency of specific CAM therapies. Higher patient education level and use by family and friends were significantly associated with CAM use. The high level of use of potentially disease modifying or interacting herb supplements may be of concern.

Pediatric natural health products recommended by chiropractic and naturopathic doctors in Canada.

OBJECTIVES: To assess chiropractic (DC) and naturopathic doctors' (ND) pediatric care natural health product (NHP) recommendations. DESIGN: Surveys were developed in collaboration with DC and ND educators, and delivered as an on-line national survey. NHP dose, form of delivery, and indications across pediatric age ranges (from newborn to 16 years) for each practitioner's top five NHPs were assessed. Data were analyzed using descriptive statistics, t-tests, and non-parametric tests. RESULTS: Of the 421 respondents seeing one or more pediatric patients per week, 172 (41%, 107 DCs, 65 NDs) provided 440 NHP recommendations, categorized as: vitamins and minerals (89 practitioners, 127 recommendations), probiotics (110 practitioners, 110 recommendations), essential fatty acids (EFAs: 72 practitioners, 72 recommendations), homeopathics (56 practitioners, 66 recommendations), botanicals (29 practitioners, 31 recommendations), and other NHPs (33 practitioners, 34 recommendations). Indications for the NHP recommendations were tabulated for NHPs with 10 or more recommendations in any age category: 596 total indications for probiotics, 318 indications for essential fatty acids, 138 indications for vitamin D, and 71 indications for multi-vitamins. CONCLUSIONS: This is the first study documenting the pediatric NHP recommendations of two popular complementary medicine professions. Common NHPs at standard doses are the most frequently recommended products, with use and doses adjusted according to age. High-quality evidence regarding the efficacy, safety, and dosing for NHP use in children is scarce; development of evidence-informed pediatric guidelines is recommended, particularly for the most commonly used and recommended NHPs.

Use of selected complementary and alternative medicine (CAM) treatments in veterans with cancer or chronic pain: a cross-sectional survey.

BACKGROUND: Complementary and alternative medicine (CAM) is emerging as an important form of care in the United States. We sought to measure the prevalence of selected CAM use among veterans attending oncology and chronic pain clinics and to describe the characteristics of CAM use in this population. METHODS: The self-administered, mail-in survey included questions on demographics, health beliefs, medical problems and 6 common CAM treatments (herbs, dietary supplements, chiropractic care, massage therapy, acupuncture and homeopathy) use. We used the chi-square test to examine bivariate associations between our predictor variables and CAM use. RESULTS: Seventy-two patients (27.3%) reported CAM use within the past 12 months. CAM use was associated with more education (p = 0.02), higher income (p = 0.006), non-VA insurance (p = 0.003), additional care outside the VA (p = 0.01) and the belief that lifestyle contributes to illness (p = 0.015). The diagnosis of chronic pain versus cancer was not associated with differential CAM use (p = 0.15). Seventy-six percent of CAM non-users reported that they would use it if offered at the VA. CONCLUSION: Use of 6 common CAM treatments among these veterans is lower than among the general population, but still substantial. A large majority of veterans reported interest in using CAM modalities if they were offered at the VA. A national assessment of veteran interest in CAM may assist VA leaders to respond to patients' needs.

Status of credentialing alternative providers within a subset of U.S. academic health centers.

BACKGROUND: Complementary and alternative medicine (CAM) clinical services are increasingly provided within conventional health care settings. OBJECTIVE: To determine how a subset of U.S. academic health centers is credentialing CAM providers. DESIGN: An electronic survey was created focusing on the credentialing method utilized for six specific types of CAM clinical practitioners within academic medical settings. METHODS: This survey was electronically distributed to 33 academic health centers in the United States during the summer 2004. RESULTS: Ninety-five percent (95%) of academic centers surveyed provide some CAM clinical care. Acupuncture and massage are most common, with naturopathy and homeopathy least common. State licensure requirements for CAM providers appear to not be well-understood. Most commonly, CAM professionals do not receive full medical staff credentials. LIMITATIONS: Results cannot be extrapolated to remaining academic health centers within the United States. Mind-body practitioners were not included in the survey. CONCLUSIONS: Credentialing and privileges are most commonly granted via indirect methods. Variability in state licensure compounds the challenge of credentialing CAM practitioners. Suggestions for beginning discussions on guiding principles for integrating CAM practitioners within conventional settings are proposed.

Prevalence and predictors of selenium and vitamin E supplementation in a urology population.

OBJECTIVES: Preclinical and epidemiological studies have suggested the use of supplements such as selenium and vitamin E for prostate cancer (PCa) prevention; however, clinical trials have not demonstrated clear benefit in patients. This study aims to investigate the current prevalence and predictors for use of these supplements in men in a urology population. DESIGN, SUBJECTS, AND OUTCOMES MEASURED: Three hundred and twelve (312) men visiting the Princess Margaret Hospital Ambulatory Urology Clinic were enrolled in this University Health Network Research Ethics Board-approved questionnaire-based study investigating supplement use, reasons for use and demographic characteristics. RESULTS: It was observed that 13.5% and 20.8% of the participants are currently using selenium and vitamin E, respectively, while 10.6% and 15.7% previously used selenium and vitamin E, respectively. Both education (percentage of users comparing less than college education versus college or above education: selenium: 14% versus 28%; p=0.008, vitamin E: 26% versus 41%; p=0.013) and health literacy (mean scores±standard error of the mean of users versus nonusers: selenium question 1: 1.4507±0.09576 versus 1.6083±0.07211; p=0.023, selenium question 2: 2.8750±0.04395 versus 2.7106±0.03774; p=0.000, selenium question 3: 1.4583±0.08377 versus 1.7064±0.06278; p=0.025, vitamin E question 1: 2.8036±0.04545 versus 2.7179±0.04097; p=0.010, vitamin E question 2: 1.5446±0.06698 versus 1.7077±0.07241; p=0.006) are predictors of selenium and vitamin E use on univariable analysis. On multivariable analysis education (selenium odds ratio=2.095, 95% confidence interval=1.019-4.305, p=0.044; vitamin E odds ratio=1.855, 95% confidence interval=1.015-3.338, p=0.045) remains a significant predictor of selenium and vitamin E use. Examining the data on use by education, it was found that more men with a higher education attributed their use of selenium to urologist advice (24%), and those with a lower education attributed their use of selenium to naturopath/homeopath advice (28%). CONCLUSIONS: Many men who visit urology clinics use selenium and vitamin E despite the lack of clinical support for chemoprevention. Education and health literacy are important variables in determining the use of these supplements in these men. This information may aid in addressing the needs of the diverse patient population using these supplements for the prevention of PCa.

Use of herbal supplements and nutritional supplements in the UK: what do we know about their pattern of usage?

Within the last decade there has been a dramatic increase in the sale and use of herbal supplements and food supplements by Western populations and within the UK. This increased usage has coincided with a resurgence of interest in nutritional therapy and complementary and alternative medicine (CAM) therapies, such as herbal medicine, naturopathy and homeopathy, in which therapists may provide dietary advice and advocate the use of food or herbal supplements. The rise in the use of CAM therapies by the UK population can be attributed to several factors, including: promotion via health programmes and the media; a change in public attitudes; training of more nutritional and CAM therapists as a result of the increased availability of courses; a greater use of CAM and food and herbal supplements, particularly by patients with cancer. The aim of the present paper is to identify the pattern of usage of food and herbal supplements in the UK.

Herbal and other complementary medicine use by Texas midwives.

This cross-sectional survey sought to document complementary and alternative medicine (CAM) use by Texas midwives, as well as to determine whether licensed direct-entry midwives (LMs) and certified nurse-midwives (CNMs) differed significantly in their patterns of use. All respondents (n = 69) indicated that they used, recommended, or referred their clients for at least one CAM therapy during the preceding year. Ninety percent (90%) of respondents used, recommended, or referred their clients for an herbal remedy (not including homeopathic tinctures). Herbal therapies were among the top three modalities recommended for 7 of 12 (58%) clinical indications. Herbs were the most salient CAM therapy used for cervical ripening (83%), followed closely by use for nausea, vomiting, and hyperemesis (80%), and labor induction (77%). Herbal therapies also constituted 50% or more of the CAM therapies used for the following indications: anemia/iron supplementation (70%), perineal healing (66%), and anxiety/stress/fatigue (50%). LM respondents used, recommended, or referred their clients for a greater number of herbal therapies compared to CNMs. While several of the CAM modalities used or recommended by Texas midwives show potential for clinical benefit, few have been studied sufficiently to determine their efficacy or safety during pregnancy.

Top-10 list of herbal and supplemental medicines used by cosmetic patients: what the plastic surgeon needs to know.

BACKGROUND: Widespread use of herbal medications/supplements among the presurgical population may have a negative effect on perioperative patient care. Thus, the authors' goal was to identify the prevalence of such use in a cosmetic surgery patient population compared with use among the general public; to assess physician awareness of proper management of these herbal medications/supplements; and to review the literature to provide rational strategies for managing perioperative patients taking these remedies. METHODS: To assess patient (n = 100) and general public (n = 100) usage rates, open-ended lists of (1) the most common herbal medications/supplements and (2) homeopathic treatments were compiled. Board-certified plastic surgeons (n = 20) were then given the same list of herbs/supplements and surveyed on their awareness of these treatments and perioperative side effects. RESULTS: The usage rate for cosmetic versus public surveys for herbal medicines/supplements was 55 percent versus 24 percent (p < 0.001), with 35 percent versus 8 percent (p < 0.001) engaging in homeopathic practices, respectively. Cosmetic patients' top four herbal/supplements of usage were chondroitin (18 percent), ephedra (18 percent), echinacea (14 percent), and glucosamine (10 percent). The top four used by the general public were echinacea (8 percent), garlic (6 percent), ginseng (4 percent), and ginger (4 percent). The physician survey demonstrated awareness of 54 percent of the listed supplements/herbal medicines, 85 percent of which were not suggested to be discontinued preoperatively, with only ephedra achieving 100 percent physician discontinuation preoperatively. CONCLUSIONS: Herbal medicines and supplements displayed greater prevalence in the cosmetic surgery population than in the population at large. Furthermore, side effects and potential complications warrant addressing these remedies as pharmaceuticals rather than as safe and "natural." Thus, a descriptive "top-10" list with perioperative recommendations was compiled for the plastic surgeon.

Herbal and homeopathic medication use in pediatric surgical patients.

BACKGROUND: Patients who present for surgery may be using herbal or homeopathic preparations; adverse effects of some of these substances include bleeding, cardiovascular changes, and liver dysfunction. Little information is available on the frequency of use in the pediatric surgical population. METHODS: With institutional approval, a survey was conducted to assess the use of vitamins, nutritional supplements, or herbal or homeopathic preparations in children presenting for surgery in five geographically diverse centers in the USA. RESULTS: A total of 894 completed surveys showed that overall, 3.5% of pediatric surgical patients had been given herbal or homeopathic medications in the 2 weeks prior to surgery. Most substances were prescribed by parents. The use of these medications did not differ between children with coexisting diseases and those without; use was also not different among ethnic groups or by residence setting (city, suburban, rural). There was a significant difference between the west coast centers in the study compared with the rest of the country (7.5% of patients in Palo Alto, CA; 5.5% of patients in Seattle, WA; 1.5% of patients in Chicago, IL; and 1.9% in Virginia and Delaware used herbal or homeopathic remedies). The most prevalent substance given to children presenting for elective surgery was Echinacea. CONCLUSIONS: Herbal and homeopathic medications are used by a small percentage of pediatric patients presenting for elective pediatric surgery patients. Use of these substances should be addressed in the preoperative history.

The usage of complementary therapies by dermatological patients: a systematic review.

Complementary medicine (CM) is more popular than ever before. Dermatology has not remained unaffected by this trend. The aim of this systematic review was to summarize all surveys of dermatological patients regarding the usage of CM. Three independent literature searches were carried out. Data were extracted in a predefined, standardized way and evaluated descriptively. Seven surveys met the inclusion/exclusion criteria. Collectively they show a high but variable prevalence of CM. Lifetime prevalence ranged from 35 to 69%. The most frequently used treatment modalities comprise homoeopathy, herbalism and food supplements. With this high level of prevalence, research into the potential risks and benefits of CM is urgently needed. Dermatologists should consider discussing CM openly with their patients.
