Complementary and Alternative Medicine and Influenza Vaccine Uptake in US Children

Effects of religious and cultural beliefs on vaccine attitudes in a Hispanic immigrant population in the United States

Hispanic Immigrants (HI) have lower vaccination rates than their non-Hispanic white counterparts. Culturally appropriate interventions are more influential in evoking change among viewers; therefore, it is important to understand the cultural factors of specific ethnic groups. In this study, we identify cultural barriers to vaccination of Hispanic Immigrants. An electronic survey was administered among HI parents living in the United States. Using structural equation modeling, we found that high religious practice and positive religious beliefs towards vaccination correspond with positive vaccine attitudes (+0.20 and +0.587, respectively). Trust in institutions is strongly correlated with strong positive vaccine attitudes (+0.734). While trusting one's folk practitioner more than a medical doctor leads to negative vaccine attitudes (-0.596), the use of home remedies is associated with positive vaccine attitudes (+0.486). The cultural competence of a medical practitioner, especially regarding folk medicine, is essential to lower cultural barriers HI patients face in vaccination.

Research on the Mechanism and Application of Acupuncture Therapy for Asthma: A Review

Asthma is a high-risk disease based on airway hyperresponsiveness (AHR). In this review, we found that there are many studies on clinical therapy for asthma that focus on the efficacy of acupuncture therapy and its mechanisms, including the functional connectivity of different brain regions, with the aid of functional magnetic resonance imaging (fMRI), immune responses/cell recognition (innate lymphoid cells and balance of Th1/Th2 and Treg/Th17), intracellular mechanism (autophagy, endoplasmic reticulum stress, and epigenetic alteration), and ligand-receptor/chemical signaling pathway (neurotransmitter, hormone, and small molecules). In this review, we summarized the clinical and experimental evidence for the mechanisms of acupuncture therapy in asthma to offer insights into drug discovery and clinical therapy. Given the paucity of clinical studies on the mechanisms of acupuncture in the treatment of asthma, this review notably included studies based on animal models to investigate the mechanisms of acupuncture in the treatment of asthma.

A taxonomy of anti-vaccination arguments from a systematic literature review and text modelling

The proliferation of anti-vaccination arguments is a threat to the success of many immunization programmes. Effective rebuttal of contrarian arguments requires an approach that goes beyond addressing flaws in the arguments, by also considering the attitude roots-that is, the underlying psychological attributes driving a person's belief-of opposition to vaccines. Here, through a pre-registered systematic literature review of 152 scientific articles and thematic analysis of anti-vaccination arguments, we developed a hierarchical taxonomy that relates common arguments and themes to 11 attitude roots that explain why an individual might express opposition to vaccination. We further validated our taxonomy on coronavirus disease 2019 anti-vaccination misinformation, through a combination of human coding and machine learning using natural language processing algorithms. Overall, the taxonomy serves as a theoretical framework to link expressed opposition of vaccines to their underlying psychological processes. This enables future work to develop targeted rebuttals and other interventions that address the underlying motives of anti-vaccination arguments.

Endorsement of alternative medicine and vaccine hesitancy among physicians: A cross-sectional study in four European countries

Vaccine hesitancy has become a threat to public health, especially as it is a phenomenon that has also been observed among healthcare professionals. In this study, we analyzed the relationship between endorsement of complementary and alternative medicine (CAM) and vaccination attitudes and behaviors among healthcare professionals, using a cross-sectional sample of physicians with vaccination responsibilities from four European countries: Germany, Finland, Portugal, and France (total N = 2,787). Our results suggest that, in all the participating countries, CAM endorsement is associated with lower frequency of vaccine recommendation, lower self-vaccination rates, and being more open to patients delaying vaccination, with these relationships being mediated by distrust in vaccines. A latent profile analysis revealed that a profile characterized by higher-than-average CAM endorsement and lower-than-average confidence and recommendation of vaccines occurs, to some degree, among 19% of the total sample, although these percentages varied from one country to another: 23.72% in Germany, 17.83% in France, 9.77% in Finland, and 5.86% in Portugal. These results constitute a call to consider health care professionals' attitudes toward CAM as a factor that could hinder the implementation of immunization campaigns.

The Effects of the COVID-19 Pandemic on Vaccination Hesitancy: A Viewpoint

Vaccination hesitancy is considered by the World Health Organization as a danger to global health. In recent years, vaccine hesitancy rates to COVID-19 have been studied worldwide. In our study, we aim to provide an overview of the concept of vaccine hesitancy, with regard to the post-COVID era, and to provide prevention and management strategies. A search of the international literature until March 2023 was conducted in the PubMed database. The 5723 papers found were divided into two groups: prior to the COVID-19 era and from 2021 onward. Papers about the vaccine hesitation phenomenon are becoming more common during the SARS-CoV-2 pandemic and following the marketing that the vaccine companies have carried out on the different types of COVID-19 vaccines. It is advisable that healthcare authorities, at the national and international level, as well as healthcare professionals, at the local level, should promote a series of activities to reduce the vaccine hesitancy rate.

Cross-sectional survey and Bayesian network model analysis of traditional Chinese medicine in Austria: investigating public awareness, usage determinants and perception of scientific support

OBJECTIVES

Despite the paucity of evidence verifying its efficacy and safety, traditional Chinese medicine (TCM) is expanding in popularity and political support. Decisions to include TCM diagnoses in the International Classification of Diseases 11th Revision and campaigns to integrate TCM into national healthcare systems have occurred while public perception and usage of TCM, especially in Europe, remains undetermined. Accordingly, this study investigates TCM's popularity, usage and perceived scientific support, as well as its relationship to homeopathy and vaccinations.

DESIGN/SETTING

We performed a cross-sectional survey of the Austrian population. Participants were either recruited on the street (in-person) or online (web-link) via a popular Austrian newspaper.

PARTICIPANTS

1382 individuals completed our survey. The sample was poststratified according to data derived from Austria's Federal Statistical Office.

OUTCOME MEASURES

Associations between sociodemographic factors, opinion towards TCM and usage of complementary medicine (CAM) were investigated using a Bayesian graphical model.

RESULTS

Within our poststratified sample, TCM was broadly known (89.9% of women, 90.6% of men), with 58.9% of women and 39.5% of men using TCM between 2016 and 2019. Moreover, 66.4% of women and 49.7% of men agreed with TCM being supported by science. We found a positive relationship between perceived scientific support for TCM and trust in TCM-certified medical doctors (ρ=0.59, 95% CI 0.46 to 0.73). Moreover, perceived scientific support for TCM was negatively correlated with proclivity to get vaccinated (ρ=-0.26, 95% CI -0.43 to -0.08). Additionally, our network model yielded associations between TCM-related, homeopathy-related and vaccination-related variables.

CONCLUSIONS

TCM is widely known within the Austrian general population and used by a substantial proportion. However, a disparity exists between the commonly held public perception that TCM is scientific and findings from evidence-based studies. Emphasis should be placed on supporting the distribution of unbiased, science-driven information.

A taxonomy of risk-associated alternative health practices: A Delphi study

Defining alternative health care and the recording of associated adverse events and harm remains problematic. This Canadian study aimed to establish and classify risk-associated alternative health practices in a Delphi study undertaken with an interdisciplinary panel of 17 health experts in 2020. It provides a new functional definition of alternative health care and an initial taxonomy of risk-associated alternative health care practices. A number of risk-associated practices were identified and categorized into general practices that conflict with biomedical care or largely untested therapies, alternative beliefs systems, physical manipulative alternative therapies, and herbal and nutritional supplements. Some risk significant harms including major physical injuries or even death. The lack of systematic methods for recording adverse events in alternative health care makes establishing the frequency of such events challenging. However, it is important that people engaging with alternative health care understand they are not necessarily risk-free endeavours, and what those risks are.

Vaccination conspiracy beliefs among social science & humanities and STEM educated people-An analysis of the mediation paths

Understanding vaccine hesitancy is becoming increasingly important, especially after the global outbreak of COVID-19. The main goal of this study was to explore the differences in vaccination conspiracy beliefs between people with a university degree coming from different scientific fields-Social Sciences & Humanities (SH) and Science, Technology, Engineering and Mathematics (STEM). The study was conducted on an online convenience sample of respondents with college and university degrees in Croatia (N = 577). The results revealed that respondents educated in SH proved to be more prone to vaccination conspiracy beliefs. The indirect effect through science literacy was confirmed, while this was not the case for the indirect effects through health beliefs (natural immunity beliefs) and trust in the healthcare system. However, all three variables were important direct predictors of vaccination conspiracy beliefs. Female gender and religiosity were positively correlated with vaccination conspiracy beliefs, while age was not a statistically significant predictor. The authors concluded by emphasizing the necessity of the more theoretically elaborated approaches to the study of the educational and other socio-demographic differences in vaccine hesitancy.

Results of a national survey on knowledge and use of complementary and alternative medicine by paediatricians

INTRODUCTION

The use of certain Complementary and Alternative Medicines (CAM) in children has been documented in Spain. The main aim of this study is to estimate the knowledge, recommendations, and use of CAM by Spanish paediatricians.

MATERIAL AND METHODS

A national study was conducted from June to July 2020 using an online questionnaire. Two e-mails were sent to paediatricians who were members of the Spanish Association of Paediatrics (AEP).

RESULTS

Out of 1414 responses received, acupuncture was considered as a science by 31.8%. Homeopathy was recommended to parents by 28.1%. CAM was used by 21.3% of physicians, at least once, to improve their own health. Only 3.8% had ever replaced a conventional treatment with CAM. The following variables were associated with a greater disposition to prescribe homeopathy: female, age over 45 years old, paediatricians working in Primary Care, and paediatricians working in private healthcare.

CONCLUSIONS

This AEP Committee on Medicines questionnaire provides new data that should be considered alarming and should ask for a serious thinking on the use of CAM in Spain. Some paediatricians are recommending parents to give treatments not supported by scientific evidence to their children. This practice could be potentially harmful, especially when conventional treatment is being replaced.

Complementary medicine use and flu vaccination - A nationally representative survey of US adults

BACKGROUND

Prior research presented inconsistent results with less, equal or higher vaccination rates among patients using complementary medicine. Given that complementary medicine includes a wide range of therapies, variable vaccination patterns may occur within consultations with different professions. This analysis aims to to evaluate differences between categories of complementary medicine regarding vaccination behavior among US adults.

METHODS AND RESULTS

This analysis used data from the 2017 National Health Interview Survey (NHIS; n = 26,742; response rate 80.7%). Prevalences of flu vaccination, consultations with complementary medicine practitioners in the past 12 months and their potential interactions were examined. 42.7% of participants had received flu vaccination in the past 12 months, 32.4% had seen one or more complementary medicine practitioner. Users of any type of complementary medicine were as likely as non-users to have received a flu vaccination (44.8% users versus 41.7% non-users; p = 0,862; adjusted odds ratio [AOR] = 1.01, 95% confidence interval [CI] = 0.95-1.07). Regarding specific complementary medicine types, individuals consulting with naturopaths (p < 0.001; AOR = 0.67, 95 %CI = 0.54-0.82), homeopaths (p < 0.001; AOR = 0.55; 95 %CI = 0.44-0.69) and chiropractors (p = 0.016; AOR = 0.9, 95 %CI = 0.83-0.98) were less likely, while other complementary medicine approaches showed no significant association with flu vaccination behavior. Independent predictors for a flu shot were prior diabetes, cancer, current asthma, kidney disease, overweight and current pregnancy. As well, higher educational level, age, ethnicity, health insurance coverage and having seen a general physician or medical specialist in the past 12 months were also associated with a higher vaccination rate.

CONCLUSIONS

Complementary medicine users were equally likely to receive an influenza vaccination compared with non-users. Different complementary therapies showed varied associations with vaccination behavior. Further analyses may be needed to distinguish influencing factors among patients' vaccination behavior.

Attitudes, beliefs, and self-use of Kabasura Kudineer among urban and rural population in Tamil Nadu, India: A comparative cross-sectional study

Context:

During an earlier outbreak of dengue (DENV), chikungunya (CHIKV) and swine flu in Tamil Nadu, India, Kabasura Kudineer and Nilavembu Kudineer were used to control the febrile episodes. No research is conducted in the past to understand the attitude and beliefs of people towards using Kabasura Kudineer as a means to improve immunity in people, especially in Tamil Nadu, the birthplace of Siddha medicine which led the researcher to conduct the study.

Aims:

The researcher in the present paper aims to understand the attitude, belief and self-use of Kabasura Kudineer among people in Tamil Nadu, India.

Settings and Design:

A cross-sectional questionnaire survey was conducted among various people in Tamilnadu, India wherein data was collected from 200 participants.

Methods and Material:

A cross-sectional study involving explanatory/descriptive research design was considered for the study.

Statistical Analysis Used:

For the analysis of collected data statistical package for SPSS software version 25.0 was used.

Results:

The urban participants who participated in the study were 80.5% and the rural participants were 19.5%. The significant P value (0.002) indicated that people use kabasura kudineer because allopathic medicine is less effective medicine and the significant P value (0.001) shows that kabasura kudineer is taken as a self-medication among Tamil Nadu people.

Conclusions:

The findings of the study revealed the better empowerment of people in the select region towards the use of Kabasura Kudineer.

Using classification and regression tree analysis to explore parental influenza vaccine decisions

BACKGROUND AND OBJECTIVES

Influenza poses a public health threat for children and adults. The CDC recommends annual influenza vaccination for children <18 years, yet vaccine uptake remains low for children (57.9%) and adults (37.1%). Given that parental decision-making is key in childhood vaccine uptake, there is a critical need to understand vaccine hesitancy among parents who decide not to vaccinate their children. This study aims to explore predictors of children's influenza vaccine status given parental vaccination status and examine the factors that contribute to concordance or discordance between parental and children's vaccine uptake.

METHODS

Classification and regression tree (CART) analyses were used to identify drivers of parental decisions to vaccinate their children against influenza. Hierarchy and interactions of these variables in predicting children's vaccination status were explored.

RESULTS

From a nationally representative sample of non-Hispanic Black and White parents who completed an online survey (n = 328), the main factors influencing parents' decisions to vaccinate their children were vaccine behavior following physician recommendation, knowledge of influenza recommendations for children, influenza vaccine confidence and disease risk. Among unvaccinated parents, the greatest concordance was observed among parents who usually do not get vaccinated following physician recommendation and had lower knowledge of recommendations for influenza vaccination for children. The greatest discordance was observed among unvaccinated parents who had lower hesitancy about recommended vaccines.

CONCLUSIONS

Understanding drivers of parental decisions to vaccinate themselves and their children can provide insights on health communication and provider approaches to increase influenza vaccine coverage and prevent influenza related mortality.

Boosting the Immune System, From Science to Myth: Analysis the Infosphere With Google

Background: The concept that one can “boost” immunity is a popular one. Although the only evidence-based approach to this is vaccination, the lay public is exposed to a wide range of information on how to boost immunity. The aim of this study was to analyze such information available on the Internet.

Methods and findings: We visited 185 webpages returned from a Google search on “boost immunity” and classified them by typology (blogs, commercial, government, no-profit, news, professional, scientific journals) and by using standard indicators of health information quality (JAMA score, HONCode). We then analyzed their content in terms of disease and “boosters” mentioned. Commercial and news websites represented one third of the results each. Of the 37 approaches to boost immunity recorded, the top ones were diet (77% of webpages), fruit (69%), vitamins (67%), antioxidants (52%), probiotics (51%), minerals (50%), and vitamin C (49%). Interestingly, vaccines ranked 27th, with only 12% of webpages mentioning them.

Conclusions: Commercial websites are an important component of the information available to the public on the topic, and thus contribute providing biased information.

Differences in healthcare utilisation between users and non-users of homeopathic products in Spain: Results from three waves of the National Health Survey (2011-2017)

OBJECTIVE

To compare the differences in the use of healthcare services: visits to the doctor and hospitalisation, performance of routine tests, and preventive influenza vaccination, between users and non-users of homeopathic products.

METHODS

We used the microdata for adults over 15 years old from three waves of the Spanish National Health Survey, corresponding to the years 2011, 2014 and 2017. We proposed a comparative design of a quasi-experimental type, considering as the treatment group the respondents who said that they had used homeopathic products in the past two weeks; and another group, for control, comprising respondents who said that they had not used this type of products, but only conventional medicines, with observable characteristics similar to those of the treatment group. We used a model for rare events logistics regression (relogit) to estimate the probability of using homeopathy. From the propensity score and a vector of control variables, we used techniques of genetic matching to match individuals from the treatment group with similar individuals belonging to the control group.

RESULTS

There are no statistically significant differences between users and non-users of homeopathy in visits to the general practitioner (P>|z| 0.387), to the specialist (P>|z| 0.52), in hospitalisations (P>|z| 0.592) or in the use of emergency services (P>|z| 0.109). Nor were there any statistically significant differences in the performance of routine tests, except for the faecal occult blood test, which is more prevalent in users of homeopathic products. 20.9% of users of homeopathy had done this test compared with 15.3% of non-users (P>|z| 0.022). There are also significant differences in vaccination against influenza with 12.6% of homeopathy users stating that they had been vaccinated in the last influenza campaign, against 21.0% of non-users (P>|z| <0.001). The health conditions which homeopathy users reported were constipation (OR: 1.65 CI: 1.16-2.36), malignant tumour (OR: 1.60 CI: 1.09-2.36) osteoporosis (OR: 1.49 CI: 1.05-2.10), varicose veins (OR: 1.35 CI: 1.05-1.74) and allergy (OR: 1.35 CI: 1.06-1.72).

CONCLUSIONS

Differences in the use of healthcare resources between users and non-users of homeopathic products have not been found to be statistically significant in Spain. It has been shown that most homeopathic products are used as a complement to treatment with conventional medicine. Nevertheless, our results highlight some warning signs which should raise the attention of healthcare authorities. The use of these therapies in patients with malignant tumours and the rejection of vaccines are warning signs of a possible health hazard in the long term.
