Development of the adult and child complementary medicine questionnaires fielded on the National Health Interview Survey

Exploring the Use of Traditional Medicines, Natural Health Products and Conventional Medicines: Development and Testing of the New Zealand 'All-Medicines' Questionnaire

INTRODUCTION

Traditional, complementary and alternative medicine (TCAM) are popular healthcare choices among consumers globally. The latest national data on the use of TCAM practitioners in New Zealand (NZ) were collected over a decade ago. Robust data on the use of natural health products (NHPs) and TCAM practices alongside conventional medicines are not yet available in NZ.

OBJECTIVES

This study aimed to develop and test a bespoke questionnaire (All-MedsNZ) that included comprehensive data collection elements exploring NHPs' and conventional medicines' use.

METHODS

This was a questionnaire design study involving expert panel feedback, and engagement with TCAM users, in the development process. This work comprised questionnaire development (stage 1) followed by a questionnaire-testing study (stage 2). The questionnaire was developed on the basis of literature review findings and the research team's expertise. The questionnaire content was then validated by an expert panel comprising practitioners in TCAM and conventional medicine. Then, a two-phase study was utilised to test the questionnaire. Phase 1 involved participants (NHP users) completing the web-based questionnaire and providing feedback by answering probing questions added throughout the questionnaire to evaluate users' comprehension of the questions and to identify issues with the questionnaire. In phase 2, selected participants were interviewed online to gain in-depth insights into issues identified in phase one. Based on these findings, the questionnaire was revised.

RESULTS

The expert panel (n = 9) confirmed the questionnaire had high face and content validity; most original questions were retained. In the questionnaire-testing study, 95 and 27 participants completed the phase 1 and 2 studies, respectively. Most questions achieved a high response rate of ≥ 90%, and participants had no major issues understanding and answering the questionnaire. Problematic questions were those relating to providing product barcodes and photographs, and information on product costs. Most of the NHPs data entered by participants included the brand/generic name, manufacturer/company name, main ingredient(s) and dose form. Generally, these NHP-related data were of acceptable quality. However, information on the main ingredient(s) of products entered by participants was less satisfactory: approximately one-third of the 143 NHPs recorded in the study had the main ingredient(s) missing or incorrectly stated. Interviews with participants reiterated the issues identified in the phase 1 study. The low response rates for some of the questions were partly due to participants' unpreparedness (i.e. not having NHPs/medicines on hand) to complete the questionnaire. In addition, a lack of clarity for the term 'natural health practitioner' led to confusion among some participants.

CONCLUSION

Overall, no major design-, method- or questionnaire-related issues were identified in this development and testing work. The questionnaire demonstrated adequate face and content validity and acceptability among participants. The data collected were reasonably complete and of sufficient quality for analysis. Future studies should pilot the revised All-MedsNZ questionnaire with a larger, nationally representative sample to ascertain its feasibility and utility.

Herbal Supplement Use for Evidence-Based Indications in US Adults: An Analysis of National Survey Data

Objective: Understanding the changes in consumer use of herbal products and what has influenced these changes is key in the promotion of evidence informed use. The last analysis of evidence informed herbal supplement use involved the 2002 National Health Interview Survey (NHIS) analysis. This study reproduces and expands upon that earlier analysis, with the most recent NHIS dataset to report herb use patterns. It also explores the guiding resources consulted by consumers in their decision to use. Methods: Secondary analysis of cross-sectional data from the NHIS identified the 10 herbal supplements with the most reported use in 2012. The reasons reported by the NHIS for taking herbal supplements were compared with the 2019 Natural Medicines Comprehensive Database (NMCD) to determine whether reasons cited in consumption were supported by evidence. Logistic regression models were fit according to NHIS sampling weights to examine the relationship between evidence-based use and user characteristics, guiding resources, and health care professional engagement surrounding use. Results: Of the 181 reported uses of herb supplements for a specific health condition, 62.5% were for reasons supported by evidence-based indications (EBIs). The odds of herb use consistent with evidence significantly increased for those reporting higher education status (odds ratio [OR] = 3.01, 95% confidence interval [CI] [1.70-5.34]). Herbal supplement use consistent with EBIs was more likely among those who disclosed their herb use to a health care professional (OR = 1.77, 95% CI [1.26-2.49]). Evidence-based herb use was also less frequently informed by Media sources (OR = 0.43, 95% CI [0.28-0.66]) compared with non-EBI use. Conclusion: Approximately 62% of the reasons cited for taking the most consumed herbs in 2012 were in alignment with 2019 EBIs. This increase may be due to improved awareness of health care professionals and/or an increase of evidence for traditional uses of herbal products. Future research should explore the role of each of these stakeholders in improving evidence-based herb use in the general population.

Scaling Family Voices and Engagement to Measure and Improve Systems Performance and Whole Child Health: Progress and Lessons from the Child and Adolescent Health Measurement Initiative

BACKGROUND

The 1997 legislation authorizing the United States Child Health Insurance Program sparked progress to measure and publicly report on children's healthcare services quality and system performance. To meet the moment, the national Child and Adolescent Health Measurement Initiative (CAHMI) public-private collaboration was launched to put families at the center of defining, measuring and using healthcare performance information to drive improved services quality and outcomes.

METHODS

Since 1996 the CAHMI followed an intentional path of collaborative action to (1) articulate shared goals for child health and advance a comprehensive, life-course and outcomes-based healthcare performance measurement and reporting framework; (2) collaborate with families, providers, payers and government agencies to specify, validate and support national, state and local use of dozens of framework aligned measures; (3) create novel public-facing digital data query, collection and reporting tools that liberate data findings for use by families, providers, advocates, policymakers, the media and researchers (Data Resource Center, Well Visit Planner); and (4) generate field building research and systems change agendas and frameworks (Prioritizing Possibilities, Engagement In Action) to catalyze prevention, flourishing and healing centered, trauma-informed, whole child and family engaged approaches, integrated systems and supportive financing and policies.

CONCLUSIONS

Lessons call for a restored, sustainable family and community engaged measurement infrastructure, public activation campaigns, and undeterred federal, state and systems leadership that implement policies to incentivize, resource, measure and remove barriers to integrated systems of care that scale family engagement to equitably promote whole child, youth and family well-being. Population health requires effective family engagement.

Situating Meditation Apps Within the Ecosystem of Meditation Practice: Population-Based Survey Study

BACKGROUND

Meditation apps have the potential to increase access to evidence-based strategies to promote mental health. However, it is currently unclear how meditation apps are situated within the broader landscape of meditation practice and what factors may influence engagement with them.

OBJECTIVE

This study aimed to clarify the prevalence and correlates of meditation app use in a population-based sample of individuals with lifetime exposure to meditation in the United States. In addition, we sought to identify the concerns and desired features of meditation apps among those with lifetime exposure to meditation.

METHODS

A total of 953 participants completed an initial screening survey. Of these 953 participants, 434 (45.5%) reported lifetime exposure to meditation and completed a follow-up survey (434/470, 92.3% response rate) assessing their meditation app use, anxiety, depression, loneliness, initial motivation for meditation, and concerns about and desired features of meditation apps.

RESULTS

Almost half (434/953, 45.5%) of the participants who completed the screening survey reported lifetime exposure to meditation. Among those with lifetime exposure to meditation (ie, meditators), more than half (255/434, 58.8%) had used meditation apps at least once in their lives, and 21.7% (94/434) used meditation apps weekly or daily (ie, active users). Younger age, higher anxiety, and a mental health motivation for practicing meditation were associated with lifetime exposure to meditation apps. Among meditators, those with lifetime exposure to meditation apps were more likely to report concerns about apps, including concerns regarding the cost and effectiveness of apps, time required for use, technical issues with apps, and app user-friendliness. Meditators who used meditation apps weekly or daily (ie, active users) were younger, less likely to be men and non-Latinx White individuals and have lower income, and more likely to have an initial spiritual motivation for meditation. Active users reported more concerns regarding usability and technical problems and were less likely to report disinterest in apps. Headspace and Calm were the most frequently used apps. Tips and reminders for practice, encouragement of "mini" practices, and mental health content were the most desired features. Participants were less interested in social features (eg, the ability to communicate with other users or teachers).

CONCLUSIONS

Meditation apps are commonly used by meditators in the United States, with a higher use among certain demographic groups. Future studies may increase user engagement in meditation apps by addressing concerns (eg, cost and effectiveness) and incorporating desired features (eg, tips and reminders for practice).

Trends and characteristics of Tai Chi and Qi Gong use among U.S. adults: Results from the 2007-2017 National Health Interview Survey

OBJECTIVE

To provide updated information about the prevalence, patterns, and predicting factors of Tai Chi and Qigong (TCQ) use among U.S. adults to better inform the future directions of TCQ application and research.

METHODS

Using 2007, 2012, and 2017 National Health Interview Survey, we examined the trends and characteristics of TCQ use by descriptive analysis, Wald F chi-square test, and multivariable logistic regression models among U.S. adults (n = 85,360), adjusting for the complex sampling design.

RESULTS

The prevalence use of TCQ among U.S. adults use was 1.17% in 2007, 1.27% in 2012, and 1.70% in 2017, which presents a 64% increase from 2007 to 2017 (p < 0.0001). Correlates of TCQ use are older adults (≥ 65 years old), Asians, having higher education levels, having lower income, and being more physically active (p < 0.001). The greater prevalence of TCQ use in 2017 than in 2012 occurred in some vulnerable demographic subgroups, including older adults, people with income less than $35,000/year, and those who were physically inactive. Those with delayed access to the conventional medical care system (e.g., had difficulty getting through on phone; couldn't get an appointment soon enough; had to wait too long to see doctor;)were also more likely to use TCQ (p < 0.001).

CONCLUSIONS

The use of TCQ has significantly increased among U.S. adults from 2007 to 2017. Given that the greatest increases in use of TCQ were among older adults, females, low-income individuals, and people who were physically inactive, TCQ may serve as age-appropriate, cost-effective, mind-body exercises for these groups of populations to help ameliorate health disparities.

Motivation for Meditation and its Association with Meditation Practice in a National Sample of Internet Users

Objectives

There is limited understanding of what motivates people to initiate and sustain a meditation practice. This study investigates initial and current motivations for meditation, demographic variability in motivations, and associations with ongoing and lifetime meditation practice.

Methods

A national sample of internet users were recruited to examine initial and current motivations for meditation practice.

Results

953 participants completed initial screening and 470 (49.3%) reported exposure to meditation practice. 434 (92.3%) completed a follow-up assessment. Participants most frequently reported mental health/stress alleviation as an initial motivation (n = 322, 74.2%) followed by spiritual (n = 122, 28.1%), physical health (n = 69, 15.9%), awakening/enlightenment (n = 64, 14.7%), cultural (n = 51, 11.8%) and other (n = 33, 7.6%). Participants reported a mean of 1.52 (SD = 0.83) initial motivations. Among those currently meditating, a significant increase in the number of motivations was found between initial and current motivations (1.60 [SD = 0.89] and 2.11 [SD = 1.16]), for initial and current motivations, respectively, Cohen's d = 0.45). The number of motivations was positively associated with meditation practice. Initial mental health motivation was found to be negatively associated with current and lifetime meditation practice, whereas spiritual motivation was found to be positively associated.

Conclusions

While meditation started as a tool for spiritual attainment, findings suggest that it is predominantly used in the U.S. for mental health support and to manage stress. Findings suggest that both type and number of motivations may relate to the course of practice.

The use of complementary and alternative medicine during pregnancy: a cross-sectional study from Palestine

BACKGROUND

The use of complementary and alternative medicine (CAM) is increasing worldwide. To the best of knowledge, there is a lack of studies that assess CAM use by Palestinian women during pregnancy. This research aims to determine the prevalence of Palestinian women's use of CAM during pregnancy, the most frequently used CAM products during the pregnancy period, the main sources that encourage the use of CAM among pregnant women, and the causes of CAM use.

METHODS

A descriptive, cross-sectional study was conducted in Palestine using a questionnaire from April 2018 to March 2019. The samples were selected by convenience sampling, including currently pregnant or previously pregnant women in the Obstetrics and Gynecology (OBGYN) clinic at Rafedia Hospital and in primary health care clinics in Nablus city-Palestine. The questionnaire covered socio-demographic variables, health status, types and frequency of CAM used, patients' sources of information, causes of their usage, attitudes, and beliefs.

RESULTS

Four hundred currently or previously pregnant women participated. Three hundred fifty-five (91.5%) used at least one method of CAM during pregnancy. Most women used at least one method of biologically-based therapies during pregnancy (87.7%). One hundred and one pregnant women (26.7%) utilised at least one type of herb during pregnancy. The most-reported herb used by 12.3% of participants was anise. Of the mind-body therapies, prayer was the most commonly used method during pregnancy (8.3%). Two hundred and sixty-one (65.3%) participants used CAM because they believed CAM was not harmful to them or their babies during pregnancy. Participants gained most of their information about CAM from their families (43.8%) and friends (24.3%). Approximately two-thirds of participants (64.0%) thought that obstetricians should be able to advise on commonly used CAM.

CONCLUSIONS

During pregnancy, CAM products are commonly used, and it is important to determine what types are being used by women in Palestine. These findings supplement the body of knowledge on the use of CAM by pregnant women. Pregnancy care providers need to be aware to the familiar types of CAM that women use.

Engagement in Nonbiomedical Practices for Fertility Enhancement: A Scoping Review

Objectives: This scoping review aims to (1) describe the scope and coverage of the body of literature on nonbiomedical practices used for enhancing fertility, (2) summarize and map the existing evidence on the extent and types of nonbiomedical practices used, and (3) examine how the research on this topic has been conducted with particular attention paid to how participants are asked about their use of nonbiomedical practices for fertility enhancement. Design: We conducted a scoping review by which four databases were searched (PubMed, Psychinfo, Socindex, and CINHAL). Articles were screened for inclusion by two researchers through a title and abstract screening followed by a full-text screening. Data were extracted from included articles and results summarized and compared across studies and regions. Results: A total of 32 studies were identified from 16 countries in five regions of the world. The majority of studies were clinic-based, primarily recruiting participants from fertility clinics in urban and suburban areas. More than half of the studies included only women, a few studies included only men, and the remainder of studies included both men and women. Most quantitative studies reported the prevalence of nonbiomedical practice use, which ranged from 8% to 83%; however, there was variation across studies regarding the time frame for which these percentages were derived. Few studies reported on other measures of the extent of use such as duration or frequency. A variety of nonbiomedical practices were identified with biologically based treatments, particularly herbal medicine use, being the most common followed by religious and spiritual interventions. Regional differences were identified. Variation in the wording and format of the question(s) used in survey instruments asking participants about their use of nonbiomedical practices exists and may impact participants' reporting of use. Conclusions: Infertility affects millions of individuals worldwide often with severe social, emotional, and financial consequences. To enhance fertility and, in some cases, overcome infertility, many individuals and couples are engaging in a variety of nonbiomedical practices. This scoping review describes the scope and nature of the existing literature on the use of nonbiomedical practices for fertility enhancement and highlights important gaps and limitations in the conduct of this research. A more comprehensive and inclusive investigation of nonbiomedical practices for enhancing fertility is needed to improve our understanding of how individuals and couples are managing infertility, identify educational and counseling needs, and to improve research related to effectiveness and safety of nonbiomedical practices.

Primary care patients' use of conventional and complementary medicine for chronic low back pain

Purpose

To investigate among primary care patients and their physicians in western Switzerland the prevalence of use, perceived usefulness, and communication about common treatments for chronic or recurrent low back pain (crLBP) including complementary medicine (CM).

Patients and methods

A cross-sectional cluster observational study involving 499 crLBP patients visiting 45 primary care physicians (PCPs) was conducted from November 1, 2015, to May 31, 2016. Patients and primary care physicians completed questionnaires about lifetime use and usefulness of 30 crLBP therapies. We conducted multivariate analyses of factors associated with therapy use, including sociodemographic variables, pain duration, insurance coverage, and primary care physicians’ characteristics.

Results

The five most frequent modalities used at least once by patients were physiotherapy (81.8%), osteopathic treatment (63.4%), exercise therapy (53.4%), opioids (52.5%), and therapeutic massage (50.8%). For their PCPs, the five most useful therapies were physiotherapy, osteopathic treatment, yoga, meditation, and manual therapy. In multivariate analysis, the use of physiotherapy was significantly associated with longer pain duration; osteopathic treatment was associated with age under 75 years, female gender, higher education, and CM insurance coverage. Exercise therapy was associated with non-smoking and longer pain duration. Smokers were more likely and patients of PCPs with CM training were less likely to have used opioids. During their lifetime, 86.6% of the participants had used at least one CM therapy to manage their crLBP, with a mean of 3.3 (SD=2.9) therapies used per participant; 46.1% of participants reported that their PCP did not enquire about CM use. Among CM users, 64.7% informed their PCP about it.

Conclusion

Patients with crLBP use a variety of treatments, including self-prescribed and unreimbursed therapies, most frequently physiotherapy and osteopathy. The results suggest that PCPs should systematically discuss with their patients the treatments they tried to manage crLBP, including CM.

Trends in Yoga, Tai Chi, and Qigong Use Among US Adults, 2002-2017

OBJECTIVES

To examine the characteristics and temporal trends of yoga, tai chi, and qigong (YTQ) use among US adults.

METHODS

Using the 2002, 2007, 2012, and 2017 National Health Interview Surveys, we examined the prevalence, patterns, and predicting factors of YTQ use by Taylor series linear regression, the Wald F χ² test, and multivariable logistic regression models (n = 116 404).

RESULTS

YTQ use increased from 5.8% in 2002 to 14.5% in 2017 (P ≤ .001). Only 6.6% of YTQ users were referred by their medical doctors, and approximately one third disclosed their use of YTQ to medical professionals. Reasons for using YTQ included (1) YTQ was beneficial, (2) YTQ focused on the whole person, and (3) YTQ was natural. Acute and chronic pain, arthritis, and depression were the top 3 medical conditions for which people used YTQ the most.

CONCLUSIONS

YTQ use is increasing substantially, mainly because of its natural and holistic healing approach toward health and chronic diseases. Future studies aiming to explore how to best integrate YTQ into the current health care system are warranted.

Patterns of conventional and complementary non-pharmacological health practice use by US military veterans: a cross-sectional latent class analysis

BACKGROUND

Non-pharmacological therapies and practices are commonly used for both health maintenance and management of chronic disease. Patterns and reasons for use of health practices may identify clinically meaningful subgroups of users. The objectives of this study were to identify classes of self-reported use of conventional and complementary non-pharmacological health practices using latent class analysis and estimate associations of participant characteristics with class membership.

METHODS

A mailed survey (October 2015 to September 2016) of Minnesota National Guard Veterans from a longitudinal cohort (n = 1850) assessed current pain, self-reported overall health, mental health, substance use, personality traits, and health practice use. We developed the Health Practices Inventory, a self-report instrument assessing use of 19 common conventional and complementary non-pharmacological health-related practices. Latent class analysis was used to identify subgroups of health practice users, based on responses to the HPI. Participants were assigned to their maximum-likelihood class, which was used as the outcome in multinomial logistic regression to examine associations of participant characteristics with latent class membership.

RESULTS

Half of the sample used non-pharmacological health practices. Six classes of users were identified. "Low use" (50%) had low rates of health practice use. "Exercise" (23%) had high exercise use. "Psychotherapy" (6%) had high use of psychotherapy and support groups. "Manual therapies" (12%) had high use of chiropractic, physical therapy, and massage. "Mindfulness" (5%) had high use of mindfulness and relaxation practice. "Multimodal" (4%) had high use of most practices. Use of manual therapies (chiropractic, acupuncture, physical therapy, massage) was associated with chronic pain and female sex. Characteristics that predict use patterns varied by class. Use of self-directed practices (e.g., aerobic exercise, yoga) was associated with the personality trait of absorption (openness to experience). Use of psychotherapy was associated with higher rates of psychological distress.

CONCLUSIONS

These observed patterns of use of non-pharmacological health practices show that functionally similar practices are being used together and suggest a meaningful classification of health practices based on self-directed/active and practitioner-delivered. Notably, there is considerable overlap in users of complementary and conventional practices.

Use and Nondisclosure of Complementary Health Approaches Among US Children with Developmental Disabilities

OBJECTIVES

Many US children use complementary health approaches (CHAs), including some modalities that may be ineffective, unsafe, and/or costly. Yet, little is known about the prevalence and correlates of CHA use among children with developmental disabilities (DDs), as well as parent nondisclosure of CHAs used for children with DDs to health care providers. We, therefore, aimed to profile the use and nondisclosure of CHAs among US children with DDs.

METHODS

We analyzed data from the 2012 National Health Interview Survey, which included the most recent Child Complementary and Alternative Medicine Supplement. The study sample was comprised of 2141 children with DDs aged 4 to 17 years.

RESULTS

Nearly one-quarter (23%) of US children with DDs used CHAs. Among those with a personal health provider, 42% of parents did not disclose some or all CHAs used to the child's provider. The adjusted odds ratios of using CHAs were greater among those with female sex, higher household income, residences not in the South, difficulty accessing care, or comorbid conditions. CHA was most commonly used because "it is natural." Nondisclosure was associated with female sex, older age, having no functional limitations, less conventional services use, and use of fewer CHAs. The most common reason for nondisclosure was that the child's provider did not ask.

CONCLUSION

Complementary health approach use is prevalent among US children with DDs, and nondisclosure is likely among those who use CHAs. Future intervention targeting education and communication about CHAs for parents of children with DDs and their health care providers may promote disclosure.

U.S. Filipino Adults' Patterns of CAM Use and Medical Pluralism: Secondary Analysis of 2012 National Health Interview Survey

The cultural health beliefs of the Filipino population and colonial history of medicine in the Philippines could mean high use of complementary and alternative therapies (CAM) and increased engagement in medical pluralism (i.e., combined use of conventional medicine and CAM) among the U.S. Filipino population, the fourth largest immigrant group in the United States. However, there is limited research regarding U.S. Filipinos’ health behaviors related to CAM use and medical pluralism engagement. The purpose of this study was to explore patterns of CAM use and medical pluralism practices of Filipino adults living in the United States. Data from Filipino adult respondents of the 2012 National Health Interview Survey adult CAM supplement were analyzed to determine most common CAM used, most common conditions for which CAM was used as a treatment, reasons for using CAM for treatment of health conditions, and sources of recommendations for CAM as a treatment in this population. Dietary supplements were the most common CAM used by Filipino adults living in the United States. A small number of U.S. Filipino adults reported using CAM to treat pain-related and cardiovascular conditions, with the most common source of recommendations coming from friends and family members. Most common reasons for using CAM for treatment of health condition were: CAM is natural; CAM had a holistic approach, and CAM could be taken/practiced independently. Based on the findings of the study, Filipino adults living in the United States engage in a pluralistic approach to health by using CAM for treatment of health conditions. Analysis of the 2012 NHIS adult CAM supplement provided an overview of Filipino adults’ patterns of CAM use and medical pluralism; however, future research is still needed to explain such health behavior patterns.

Prevalence and patterns of use of mantra, mindfulness and spiritual meditation among adults in the United States

BACKGROUND

Despite a growing body of scientific literature exploring the nature of meditation there is limited information on the characteristics of individuals who use it. This is particularly true of comparative studies examining prevalence and predictors of use of various forms of meditation.

METHODS

A secondary analysis was conducted using data from the 2012 National Health Interview Survey (n = 34,525). Three popular forms of meditation were compared-mantra, mindfulness, and spiritual-to determine lifetime and 12-month use related to key sociodemographic, health behavior, health status, and healthcare access variables.

RESULTS

The 12-month prevalence for meditation practice was 3.1% for spiritual meditation, 1.9% for mindfulness meditation, and 1.6% for mantra meditation. This represents approximately 7.0, 4.3, and 3.6 million adults respectively. A comparison across the three meditation practices found many similarities in user characteristics, suggesting interest in meditation may be more related to the type of person meditating than to the type of practice selected. Across meditation styles use was more prevalent among respondents who were female, non-Hispanic White, college educated, physically active; who used other complementary health practices; and who reported depression. Higher utilization of conventional healthcare services was one of the strongest predictors of use of all three styles. In addition to similarities, important distinctions were observed. For example, spiritual meditation practice was more prevalent among former drinkers. This may reflect use of spiritual meditation practices in support of alcohol treatment and sobriety. Reasons for use of meditation were examined using the sample of respondents who practiced mindfulness meditation. Wellness and prevention (74%) was a more common reason than use to treat a specific health condition (30%). Common reasons for use included stress management (92%) and emotional well-being (91%), and to support other health behaviors. Meditation was viewed positively because it was self-care oriented (81%) and focused on the whole person (79%).

CONCLUSION

Meditation appears to provide an accessible, self-care resource that has potential value for mental health, behavioral self-regulation, and integrative medical care. Considering consumer preference for distinct types of meditation practices, understanding the underlying mechanisms, benefits, and applications of practice variations is important.

Chronic low back pain patients' use of, level of knowledge of and perceived benefits of complementary medicine: a cross-sectional study at an academic pain center

BACKGROUND

Chronic pain patients often use complementary medicine (CM) to alleviate their pain; however, little is known about the use of CM by chronic low back pain (cLBP) patients. We investigated the frequency of use of CM by cLBP patients, the perceived effects of these therapies, patients' knowledge regarding CM, and patient-physician communication regarding CM.

METHOD

A cross-sectional survey was conducted from November 2014 to February 2015. A questionnaire was distributed by physicians to 238 consecutive patients consulting for cLBP at the Pain Center of Lausanne University Hospital, Switzerland. Poisson regression model was used to analyze patients' level of knowledge regarding various CMs, and the logistic regression model was used to assess CM use for cLBP.

RESULTS

The questionnaire was returned by 168 cLBP patients (response rate: 70.6%). Lifetime prevalence of CM use for cLBP was 77.3%. The most commonly used therapies were osteopathy (48.8%), massage (45.2%) and acupuncture (31.6%), rated for their usefulness on a 0-10 scale as a mean ± SD of 5.4 ± 2.7, 5.9 ± 2.5 and 3.8 ± 3.2, respectively. The CM treatment best known by patients was osteopathy, followed by massage and acupuncture. If their doctors proposed CM as a treatment for cLBP, 78% of participants reported being very or somewhat likely to try CM. Respondents with CM health insurance were more likely to use CM (OR = 2.26; 95%CI: 1.07-4.78; p = 0.031) for cLBP. Respondents having experienced cLBP for more than five years were more likely to use CM to treat their cLBP than respondents having experienced cLBP for one year or less (OR = 2.84; 95%CI: 1.02-7.88; p = 0.044).

CONCLUSIONS

More than three-quarters of cLBP patients in our sample did use CM to treat their cLBP. The results showed that the most commonly used therapies were not necessarily the highest rated in terms of perceived usefulness. These results highlight the importance of developing integrative pain centers in which patients may obtain advice regarding CM treatments.

Characteristics of Adults Who Used Mindfulness Meditation: United States, 2012

OBJECTIVES

To describe estimates of the number and characteristics of persons who had used mindfulness meditation in the U.S.

POPULATION

DESIGN

Data from 108,131 adults from the 2012 National Health Interview Survey were weighted to produce national estimates representative of the U.S.

POPULATION

Persons who used mindfulness meditation were identified by their response to the question "During the past 12 months, did you use mindfulness meditation?"

RESULTS

An estimated 2,029,720 adults had used mindfulness meditation. Compared with those who did not meditate, more meditators endorsed moderate exercise (79.6% vs. 54.8%; p < 0.0001). More meditators had low-back and neck pain and headache (36.7% vs. 28.9 [p = 0.0002]; 26.4% vs. 14.7% [p<0.0001]; 19.1% vs. 12.1% [p<0.0001], respectively). More meditators reported being nervous or feeling sad at least a little of the time (60.4% vs. 37.8% and 34% vs. 23.5%, respectively; p<0.0001) and being frequently stressed (56.4% vs. 29.0%; p<0.0001).

CONCLUSIONS

Mindfulness meditation was used by an estimated 2,029,720 adults in the United States in 2012. More meditators than nonmeditators reported more pain and reported feeling nervous or sad and being stressed, suggesting a reason for using mindfulness meditation.

Complementary and alternative medicine use among US cancer survivors

PURPOSE

US cancer survivors commonly use vitamins/minerals and complementary and alternative medicine (CAM). We compare use of vitamins/minerals and CAM between adult cancer survivors and cancer-free adults and estimate annual out-of-pocket expenses.

METHODS

Data on self-reported vitamin/mineral and CAM use in the past 12 months from the cross-sectional 2012 US National Health Interview Survey were used to estimate prevalence of use and out-of-pocket expenditures. The cohort included adults with (n = 2977) and without (n = 30,551) a self-reported cancer diagnosis.

RESULTS

Approximately 79 % of cancer survivors and 68 % of cancer-free adults reported using ≥1 vitamins/minerals and/or CAM modality in the past year. Compared to cancer-free adults, cancer survivors were more likely to report use of vitamin/minerals (75 vs. 61 %, P < 0.001), non-vitamin/mineral natural products (24 vs. 19 %, P < 0.001), manipulative and body-based therapies (19 vs. 17 %, P = 0.03), and alternative medical systems (5 vs. 4 %, P = 0.04). Adult cancer survivors and cancer-free adults spent an annual estimated $6.7 billion and $52 billion out-of-pocket, respectively, on vitamins/minerals and CAM. Survivors spent 60 % of the total on vitamins/minerals ($4 billion), 18 % ($1.2 billion) on non-vitamin/mineral natural products, and 7 % ($0.5 billion) on massage.

CONCLUSIONS

Compared with cancer-free adults, a higher proportion of cancer survivors report vitamin/mineral and CAM use. Cancer survivors, who accounted for 6.9 % of the total population, accrued more than 11.4 % of the annual out-of-pocket costs on vitamins/minerals and CAM spent by US adults.

IMPLICATIONS FOR CANCER SURVIVORS

Given the high use of vitamins/minerals and CAM in cancer survivors, studies are needed to analyze health outcomes and the cost/benefit ratio of such use.

Association of complementary and alternative medicine use with symptoms and physical functional performance among adults with arthritis

BACKGROUND

Research shows high prevalence of complementary and alternative medicine (CAM) use in individuals with arthritis. Little is known about CAM use and objectively measured physical functional performance.

OBJECTIVE

The main objective was to determine if CAM use was associated with self-reported symptoms and physical functional performance in adults with arthritis. The secondary objectives were to describe the perceived helpfulness and correlates of CAM use.

METHODS

We analyzed cross-sectional data from a self-administered questionnaire and objectively measured physical functional performance prior to randomization to a self-paced exercise program or control condition (n = 401). We used the Fisher's exact test, analysis of variance, and general linear models to examine the association of CAM use with socio-demographic characteristics, symptoms and functional performance. Logistic regression computed the odds of perceiving CAM as helpful by level of use.

RESULTS

Most respondents had used CAM (76%). Dietary supplements were the most-used (53.1%). Female gender and college education predicted greater number of modalities used. Compared to non-users, use of any CAM was associated with greater fatigue and lower grip strength; relaxation techniques with lower walk distance and gait speed; dietary change with greater pain and stiffness and lower walk distance; and yoga with lower pain and stiffness, greater walk distance, chair stands, seated reach and gait, but lower grip strength. Perceived help was positively associated with the number of modalities used.

CONCLUSIONS

Associations between CAM and symptoms or functional performance were mixed. Only yoga showed positive associations; however, yoga practitioners were more physically active overall than non-practitioners.

Out-Of-Pocket Expenditures on Complementary Health Approaches Associated With Painful Health Conditions in a Nationally Representative Adult Sample

National surveys suggest that millions of adults in the United States use complementary health approaches such as acupuncture, chiropractic manipulation, and herbal medicines to manage painful conditions such as arthritis, back pain, and fibromyalgia. Yet, national and per person out-of-pocket (OOP) costs attributable to this condition-specific use are unknown. In the 2007 National Health Interview Survey, the use of complementary health approaches, the reasons for this use, and the associated OOP costs were captured in a nationally representative sample of 5,467 adults. Ordinary least square regression models that controlled for comorbid conditions were used to estimate aggregate and per person OOP costs associated with 14 painful health conditions. Individuals using complementary approaches spent a total of $14.9 billion (standard error [SE] = $.9 billion) on these approaches to manage these painful conditions. Total OOP expenditures by those using complementary approaches for their back pain ($8.7 billion, SE = $.8 billion) far outstripped OOP expenditures for any other condition; the majority of these costs ($4.7 billion, SE = $.4 billion) were for visits to complementary providers. Annual condition-specific per person OOP costs varied from a low of $568 (SE = $144) for regular headaches to a high of $895 (SE = $163) for fibromyalgia.

PERSPECTIVE

Adults in the United States spent $14.9 billion on complementary health approaches (eg, acupuncture, chiropractic manipulation, and herbal medicines) to manage painful conditions including back pain ($8.7 billion). This back pain estimate is almost one-third of the total conventional health care expenditure for back pain ($30.4 billion) and two-thirds higher than conventional OOP expenditures ($5.1 billion).

Use of complementary health approaches among children aged 4-17 years in the United States: National Health Interview Survey, 2007-2012

OBJECTIVE

This report presents national estimates of the use of complementary health approaches among children aged 4-17 years in the United States. Selected modalities are compared for 2007 and 2012 to examine changes over time.

METHODS

Data from the 2007 and 2012 National Health Interview Survey (NHIS) were analyzed for this report. The combined sample included 17,321 interviews with knowledgeable adults about children aged 4-17 years. Point estimates and estimates of their variances were calculated using SUDAAN software to account for the complex sampling design of NHIS. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level.

RESULTS

The use of complementary health approaches among children did not change significantly since 2007 (from 12.0% in 2007 to 11.6% in 2012). However, one approach, the use of traditional healers, showed a statistically significant decrease in use, from 1.1% in 2007 to 0.1% in 2012. No other significant decreases were identified. An increase in the use of yoga was observed during this period (from 2.3% in 2007 to 3.1% in 2012). Nonvitamin, nonmineral dietary supplements; chiropractic or osteopathic manipulation; and yoga, tai chi, or qi gong were the most commonly used complementary health approaches in both 2007 and 2012. Also consistent between 2007 and 2012 was that complementary health approaches were most frequently used for back or neck pain, head or chest cold, anxiety or stress, and other musculoskeletal conditions.

Trends in the use of complementary health approaches among adults: United States, 2002-2012

OBJECTIVE

This report presents national estimates of the use of complementary health approaches among adults in the United States across three time points. Trends in the use of selected complementary health approaches are compared for 2002, 2007, and 2012, and differences by selected demographic characteristics are also examined.

METHODS

Combined data from 88,962 adults aged 18 and over collected as part of the 2002, 2007, and 2012 National Health Interview Survey were analyzed for this report. Sample data were weighted to produce national estimates that are representative of the civilian noninstitutionalized U.S. adult population. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level.

RESULTS

Although the use of individual approaches varied across the three time points, nonvitamin, nonmineral dietary supplements remained the most popular complementary health approach used. The use of yoga, tai chi, and qi gong increased linearly across the three time points; among these three approaches, yoga accounted for approximately 80% of the prevalence. The use of any complementary health approach also differed by selected sociodemographic characteristics. The most notable observed differences in use were by age and Hispanic or Latino origin and race.

Cancer family caregiver depression: are religion-related variables important?

OBJECTIVE

Prevalence estimates for clinical depression among cancer family caregivers (CFC) range upwards to 39%. Research inconsistently reports risk for CFC depressive symptoms when evaluating age, gender, ethnicity, or length of time as caregiver. The discrepant findings, coupled with emerging literature indicating religiosity may mitigate depression in some populations, led us to investigate religion-related variables to help predict CFC depressive symptoms.

METHODS

We conducted a cross-sectional study of 150 CFC. Explanatory variables included age, gender, spousal status, length of time as caregiver, attendance at religious services, and prayer. The outcome variable was the Center for Epidemiological Studies Depression Scale score.

RESULTS

Compared with large national and state datasets, our sample has lower representation of individuals with no religious affiliation (10.7% vs. 16.1% national, p = 0.07 and 23.0% state, p = 0.001), higher rate of attendance at religious services (81.3% vs. 67.2% national, p < 0.001 and 30.0% state, p < 0.001), and higher rate of prayer (65.3% vs. 42.9% national, p < 0.001; no state data available). In unadjusted and adjusted models, prayer is not significantly associated with caregiver depressive symptoms or clinically significant depressive symptomology. Attendance at religious services is associated with depressive symptoms (p = 0.004) with an inversely linear trend (p = 0.002).

CONCLUSION

The significant inverse association between attendance at religious services and depressive symptoms, despite no association between prayer and depressive symptoms, indicates that social or other factors may accompany attendance at religious services and contribute to the association. Clinicians can consider supporting a CFC's attendance at religious services as a potential preventive measure for depressive symptoms.

Regional variation in use of complementary health approaches by U.S. adults

Data from the National Health Interview Survey, 2012 Use of nonvitamin, nonmineral dietary supplements (17.9%) was greater than any other complementary health approach used by U.S. adults in 2012. The use of practitioner-based chiropractic or osteopathic manipulation was nearly twice as high in the West North Central region as in the United States overall. Use of nonvitamin, nonmineral dietary supplements was highest in the Mountain, Pacific, and West North Central regions. Use of yoga with deep breathing or meditation was approximately 40% higher in the Pacific and Mountain regions than in the United States overall. Complementary health approaches are defined as "a group of diverse medical and health care interventions, practices, products, or disciplines that are not generally considered part of conventional medicine". They range from practitioner-based approaches, such as chiropractic manipulation and massage therapy, to predominantly self-care approaches, such as nonvitamin, nonmineral dietary supplements, meditation, and yoga. This report presents estimates of the four most commonly used complementary health approaches among adults aged 18 and over in nine geographic regions, using data from the 2012 National Health Interview Survey adult alternative medicine supplement.
