International prevalence of consultation with a naturopathic practitioner: a systematic review and meta-analysis.

OBJECTIVES: Naturopathy is a traditional medicine system informed by codified philosophies and principles, and an emphasis on non-pharmacologic therapeutic interventions. While naturopathy is practised by approximately 75 000-100 000 000 naturopathic practitioners in at least 98 countries, little is known about the international prevalence of history of consultation with a naturopathic practitioner. This study reports a systematic review and meta-analysis of studies describing the global prevalence of history of consultation with a naturopathic practitioner by the general population. SETTING: The included literature was identified through a systematic search of eight databases between September and October 2019, as well as the grey literature. PARTICIPANTS: Studies were included if they reported the prevalence rate of consultations with a naturopathic practitioner by the general population. INTERVENTIONS: Survey items needed to report consultations with a naturopathic practitioner as defined in the country where data was collected, and not combine naturopathic consultations with other health services or only report consulations for illness populations. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary measures used for the analysis was consultations in the previous 12 months. Other prevalence timeframes were reported as secondary measures. METHODS: Meta-analysis of prevalence data was conducted using random effects models based on individual countries and WHO world regions. RESULTS: The literature search identified eight manuscripts summarising 14 studies reporting prevalence for inclusion in the review. All included studies had a low risk of bias. Meta-analysis of the included studies by world region found the 12-month prevalence of history of naturopathy consultations ranged from 1% in the Region of the Americas to 6% in the European and Western Pacific Regions. CONCLUSIONS: There are up to sixfold differences in the prevalence of naturopathy consults over 12 months between and within world regions, which may be driven by a range of policy, legislative and social factors.

Overview of international naturopathic practice and patient characteristics: results from a cross-sectional study in 14 countries.

BACKGROUND: Naturopathy is a distinct system of traditional and complementary medicine recognized by the World Health Organization and defined by its philosophic approach to patient care, rather than the treatments used by practitioners. Worldwide, over 98 countries have practicing naturopaths, representing 36% of all countries and every world region. The contributions of naturopaths to healthcare delivery services internationally has not been previously examined. Thus, the primary intention of this research was to conduct an international survey of naturopathic practice and patient characteristics in order to gain insight to the breadth of their practices and the type of clinical conditions routinely encountered. METHODS: The cross-sectional study was conducted in naturopathic clinics in 14 countries within 4 world regions including the European (Portugal, United Kingdom, Switzerland, Spain), Americas (Canada, United States, Chile, Brazil), Western Pacific (Hong Kong, Australia, New Zealand) and African (South Africa). Naturopathic practitioners in each country were invited to prospectively complete an online survey for 20 consecutive cases. The survey was administered in four languages. RESULTS: A total of 56 naturopaths from 14 countries participated in the study, providing a mean of 15.1 cases each (SD 7.6) and 851 cases in total. Most patients were female (72.6%) and all age categories were represented with a similar proportion for 36-45 years (20.2%), 46-55 years (19.5%), and 56-65 years (19.3%). A substantial majority (75%) of patients were considered by the participant to be presenting with chronic health conditions. The most prevalent category of health conditions were musculoskeletal (18.5%), gastrointestinal (12.2%), and mental illness (11.0%). The most common treatment categories prescribed or recommended to patients by the participants were dietary changes (60.5%), lifestyle and behaviour changes (56.9%), herbal medicines (54.2%) and nutritional supplements (52.1%). Many patients were known by participants to be receiving care from a general practitioner (43.2%) or a specialist medical practitioner (27.8%). CONCLUSIONS: Naturopathic practitioners provide health care for diverse health conditions in patients in different age groups. The global population would benefit from researchers and policy makers paying closer attention to the potential risks, benefits, challenges and opportunities of the provision of naturopathic care within the community.

Western herbal medicines in the treatment of irritable bowel syndrome: A systematic review and meta-analysis.

OBJECTIVE: To evaluate the efficacy of Western herbal medicines in the treatment of irritable bowel syndrome (IBS). DESIGN: A computer-based search of MEDLINE, EMBASE, CINAHL, AMED, GreenFILE, Health Source: Nursing/Academic Edition, and the Cochrane Library was conducted. A hand-search of the bibliographies of relevant papers and previous meta-analyses and reviews was also undertaken. Trials were included in the review if they were double-blind and placebo-controlled investigating the effects of Western herbal medicines on IBS-related symptoms or quality of life. There were no language restrictions. Eligibility assessment and data extraction were performed by two independent researchers. For herbal medicines where there was more than 1 trial of similar design, data were synthesised using relative risk of symptoms improving using the random effects model. RESULTS: Thirty-three trials were identified that met all eligibility criteria. Seventeen of these evaluated peppermint essential oil, fifteen other Western herbal medicines, and one trial evaluated peppermint oil in one arm and aniseed essential oil in the other arm. Eighteen different herbal preparations were evaluated in these trials. Data suggests that a number of Western herbal medicines may provide relief of IBS symptoms. Meta-analyses suggest that peppermint essential oil is both efficacious and well-tolerated in the short-term management of IBS. Aloe vera and asafoetida also demonstrated efficacy in reducing global IBS symptoms in meta-analyses. The herbal formulas STW 5, STW 5-II and Carmint, along with Ferula assa-foetida, Pimpenella anisum oil, the combination of Curcumin and Foeniculum vulgare oil, and the blend of Schinopsis lorentzii, Aesculus hippocastanum, and peppermint essential oil also demonstrated efficacy in rigorously-designed clinical trials. CONCLUSION: A number of Western herbal medicines show promise in the treatment of IBS. With the exception of peppermint essential oil, Aloe vera, and asafoetida, however, none of the positive trials have been replicated. This lack of replication limits the capacity to make definitive statements of efficacy for these herbal medicines.

Lessons from Outside and Within: Exploring Advancements in Methodology for Naturopathic Medicine Clinical Research.

INTRODUCTION: Naturopathy is a mixture of both traditional and complementary medicine. It incorporates a broad set of health care practices that may or may not be traditional to that country or conventional medicine and are not fully integrated into the dominant health care system. Research required to evaluate or substantiate naturopathic medicine may not fall under the testing of randomized clinical trials, which opens up discussions on what is the best practice for research in naturopathic medicine. DISCUSSION: Not only do advances in health research methodology offer important opportunities to progress naturopathic research, there are also areas where the unique characteristics of naturopathic philosophy and practice can impact other areas of health research. Some of the new advances in health research methodology involve whole-system research, pragmatic trials, template for intervention description and replication protocols for complex interventions, patient-centered care models, and the pragmatic-explanatory continuum indicator summary tool for designing pragmatic trials. Discussion and critique of these health-related methodologies shows that these research methods are more suited for the philosophy and treatment options that naturopathy is based on. CONCLUSIONS: Successful implementation of naturopathic research methodologies, and translation and dissemination of research will require a substantial paradigm shift in which naturopathic practitioners adopt a greater level of responsibility for developing an evidence base for naturopathic medicine.

Sexual reproductive healthcare utilisation and HIV testing in an integrated adolescent youth centre clinic in Cape Town, South Africa.

BACKGROUND: HIV prevalence is increasing among South African youth, but HIV counselling and testing (HCT) remains low. Adolescent pregnancy rates are also high. OBJECTIVES: Innovative strategies are needed to increase HIV and pregnancy screening and prevention among youth. METHOD: The Desmond Tutu HIV Foundation Youth Centre (DTHF-YC) offers integrated, incentivised sexual and reproductive health (SRH), educational and recreational programmes. We compared HCT and contraception rates between the DTHF-YC and a public clinic (PC) in Cape Town to estimate the impact of DTHF-YC on youth contraception and HCT utilisation. RESULTS: In 2015, females < 18 years had 3.74 times (confidence interval [CI]: 3.37-4.15) more contraception visits at DTHF-YC versus PC. There were no differences in the contraception and adherence was suboptimal. DTHF-YC youth (aged 15-24 years) were 1.85 times (CI: 1.69-2.01) more likely to undergo HCT versus PC, while male youth were 3.83 times (CI: 3.04-4.81) more likely to test at DTHF-YC. Youth were a third less likely to test HIV-positive at DTHF-YC versus PC. Female sex, older age, clinic attendance for contraception and sexually transmitted infections (STIs), redeeming incentives and high DTHF-YC attendance were all independent factors associated with increased HCT. CONCLUSION: Youth were significantly more likely to access SRH services at DTHF-YC compared with the PC. The differences were greatest in contraception use by female adolescents < 18 years and HCT by male youth. Increased HCT did not increase youth HIV case detection. Data from DTHF-YC suggest that youth-friendly healthcare providers integrated into community youth spaces may increase youth HCT and contraception rates.
