Effectiveness of e-learning material on essential components of evidence-based medicine among laypersons: a randomized controlled trial

Evidence-based medicine (EBM) is helpful for laypersons' decision-making. This study aimed to evaluate the effectiveness of e-learning materials on the essential components of EBM for laypersons. We conducted a web-based, open-label, randomized controlled trial with laypersons in Japan aged ≥20 years who used the internet. Participants were randomly assigned to the intervention group with the e-learning material and the control group with only the 'Introduction' section of the same material. The primary and secondary outcomes were the self-created acquirement test scores (responding correctly with confidence) immediately after using the material and after 4 weeks. A multiple linear regression analysis was conducted. Of the 122 participants, 62 were randomly assigned to the intervention group and 59 to the control group; finally, 59 and 58, respectively, were included in the full analysis set. The mean (standard deviation) of the acquirement test score immediately after learning was 14.11 and (3.11) and 11.07 (3.88) in the intervention and control groups, respectively, indicating statistical significance (multivariable P < 0.001). The secondary long-term outcome was also statistically significant. The results showed that the e-learning material was effective for laypersons in acquiring the essential components of EBM. The material may increase laypersons' confidence in appraising health information, which can be used in decision-making.

The direct effects of media exposure on behaviors aimed at preventing COVID-19 and its indirect effects as mediated by interpersonal communication: a longitudinal study in Japan

Objective

We aimed to examine the direct effects of exposure to media information about infection-preventing behavior and its indirect effects via interpersonal communication at two time points during the pandemic.

Methods

In August 2020 and August 2021, a web-based survey of Japanese people under a declared state of emergency was conducted. We collected sociodemographic data and data on seven types of exposure to media information, three types of exposure to interpersonal communication, and six types of infection-preventing behavior.

Results

A total of 784 participants completed both surveys. Exposure to information in the mass media decreased over the year, while interpersonal communication about COVID-19-related topics increased. The direct effect of exposure to information in the media about preventive behaviors was statistically significant in the pandemic's early stages, but this was no longer true after 1 year. The indirect effect via interpersonal communication was statistically significant at both time points.

Conclusion

Our results suggest that the influence of media information on infection-preventing behavior during the pandemic was maintained over time as an indirect effect via interpersonal communication. For risk communication media strategies during pandemics, adopting strategies to generate interpersonal communication will have a sustained effect on preventive behavior.

Impact on step count by commitment-based health application

OBJECTIVE

Prior research has implied that promoting sustaining physical activity through nudges is challenging and boosting health literacy is important for the long-term establishment of behaviors. This study aimed to investigate the effects of commitment-based health application on step count and health literacy.

METHODS

A control experiment was conducted involving employees from companies located in Shizuoka Prefecture, Japan. Participants were divided into three groups: the commitment app group (utilizing a commitment-based application "Minchalle," where teams of around five members were randomly assigned to declare a target step count and report daily step count with pictures), the self-commitment group (individuals declaring a target step count and endeavoring on their own), and the control group (no intervention). Changes in step count and health literacy were examined over one month.

RESULTS

A total of 109 employees from 7 companies participated. The changes in step count were an increase of 893 steps for the commitment app group, 243 steps for the self-commitment group, and 178 steps for the control group, with a significant increase in the commitment app group compared to the control group. Regarding health literacy measures, there was significant progress in four items out of five for the commitment app group compared to the control group, and significant progress in one item for the self-commitment group compared to the control group.

CONCLUSION

Communication within the app teams, such as commitment, sharing photos of their goal achievements and provide encouraging comments to others, functioned as social nudges, suggesting the potential for an immediate increase in step count and long-term behavioral reinforcement through improved health literacy.

Cross-sectional study to identify health literacy, health behavior, and quality of life in Chofu and Komae cities in Japan: Formative research in community-based nursing practice

The Jikei Academic Nursing Practice Center for the Community developed a community nursing practice that matched community health problems and concerns in Chofu and Komae cities, suburban areas of the Tokyo Metropolis. This study aimed to identify health problems and high-risk populations via an understanding of the practice of health behaviors, health literacy, and quality of life. This was an online, cross-sectional study conducted in September 2023. In total, 1520 (Chofu: n = 1170; Komae: n = 350) participants were enrolled. Participants' demographic characteristics, health literacy, health behaviors, and quality of life scores were obtained. Sleep quality was poor compared with national data. Younger participants had higher poor health literacy, did not practice health behaviors, and had a lower quality of life. In addition, parenting and informal nursing care for family members were associated with unhealthy eating, smoking, drinking, and poor quality of life. This study found that health problems and concerns before planning were significant in increasing the salience of interventions for community residents. Based on the findings of this study, an action plan for community-wide nursing practice was created.

The association between oral health literacy and oral health-related behaviours among female adolescents in the Kingdom of Saudi Arabia: A cross-sectional study

Objectives

Oral health literacy (OHL) is suggested as an important denominator of oral health. This study aimed to identify ways to improve oral health by exploring the association between oral health literacy and oral health-related behaviours among female adolescents in the Eastern Province of the Kingdom of Saudi Arabia (KSA).

Methods

This cross-sectional study assessed OHL among 1,889 10th grade female students in the Eastern Province of the KSA. OHL was assessed using an Arabic version of the short version of the Health Literacy in Dentistry scale (A-HeLD-14). Self-reported socio-demographic information and oral health-related behaviours (toothbrushing, dental attendance, and sugary diet consumption) were also collected. The relationship between OHL and oral health-related behaviours was investigated using binary logistic regression, adjusted for socio-demographic information.

Results

The binary logistic regression analyses showed that poor OHL was significantly associated with infrequent toothbrushing (p < 0.001) and irregular dental attendance (p = 0.005) but not with consumption of sugary diets. All A-HeLD-14 domains were significantly associated with infrequent toothbrushing, and the domains concerning access, receptivity, and financial barriers were significantly associated with irregular dental attendance. The highest odds ratios (ORs) for infrequent toothbrushing were found in the domains of receptivity (OR = 4.19) and understanding (OR = 3.85) and for irregular dental attendance in the financial barriers (OR = 1.61) and access (OR = 1.49) domains, followed by the receptivity domain (OR = 1.35).

Conclusion

Poor OHL was significantly associated with infrequent toothbrushing and irregular dental attendance. Interventions focusing on OHL are warranted to improve oral health-related behaviours and thereby oral health in the population. The aspects that seem most vital to target are improved access to dental care, including the reduction of economic barriers, as well as increased awareness of oral health in the population.

Association Between Health Literacy and Understanding of Doctors' Explanations: The Yamagata Study

BACKGROUND

In Japan, the doctor-patient relationship has traditionally been characterized by a power imbalance that may contribute to communication gaps. To date, however, the link between patients' health literacy levels and their understanding of doctors' explanations of medical conditions and treatment has yet to be fully examined in Japan.

OBJECTIVE

The purpose of this study was to investigate the association between patients' health literacy level and their understanding of doctors' explanations.

METHODS

This was a cross-sectional study analyzing data derived from 11,217 questionnaires collected in July 2021 from participants of the Yamagata Study, a community-based cohort study implemented by Yamagata University since 2009.

KEY RESULTS

The results showed lower health literacy was associated with poorer understanding of physicians' explanations, adjusting for potential confounding factors. In addition to low health literacy, factors associated with lower comprehension were being male, not having a regular family doctor, and having lower self-perceived levels of health and happiness.

CONCLUSIONS

The results suggest that health care professionals need to communicate with patients according to their health literacy level and ensure they fully understand their medical condition and treatment. Medical providers need to create a better health-literate environment to enable patients and families to make decisions by themselves.

Smartphone Proficiency in Community-Dwelling Older Adults is Associated With Higher-Level Competence and Physical Function: A Population-Based Age-Specific Cross-Sectional Study

With the rapid development of information and communication technology, smartphone ownership has increased among older adults. While previous research has examined the impact of smartphone use on the health of older adults, this study focuses on the less-explored relationship between smartphone use, proficiency, and health-related outcomes including higher-level competence. The study was a cross-sectional survey of 208 community-dwelling older adults who used smartphones daily. Smartphone use, including years of use and applications, was assessed and categorized by age group. Health-related outcomes were measured, including cognitive and psychological function, higher-level competence, basic daily abilities, and physical function. The results indicated that smartphone proficiency decreased with age, with older adults primarily using basic smartphone applications. Notably, higher smartphone proficiency was positively associated with higher-level competence and physical functions. The study underscores the importance of considering smartphone proficiency when assessing older adults' life skills and physical performance in our digital society.

Investigating the relationship between health literacy and preconceptual care components during the first 14 weeks of pregnancy: a cross-sectional study

BACKGROUND AND AIM

Preconceptual care aiming to improve health is influenced by various factors including health literacy. Considering the importance and necessity of high quality preconceptual care, this study aimed to determine the relationship between health literacy and receiving components of preconceptual care prior to pregnancy.

METHODS

This cross-sectional study included 693 participants with pregnancies of less than 14 weeks gestation referred to health centers and gynecologists in Shiraz city, Iran. Multi-stage sampling was done from May 2021 to February 2022 in 18 comprehensive urban health centers and 20 gynecology offices via proportional allocation method. The data collection tool comprised a questionnaire consisting of 3 parts: (1) individual and fertility characteristics, (2) information related to the components of preconceptual care and (3) health literacy for Iranian adults. This was completed by individual participants via the self-reporting method.

RESULTS

The majority of participants were between 30 and 34 years old. They also identified as women with a university education and were predominantly unemployed. The mean health literacy of participants was 76.81%. Health literacy obtained the highest mean score in the dimension of 'understanding' and the lowest mean score in the dimension of 'access'. The frequency of preconceptual counseling, folic acid supplement consumption, exercise, blood testing, dental visits, genetic counseling, Pap smear testing and rubella, diphtheria, and hepatitis vaccinations prior to pregnancy was 66.8%, 53.8%, 45.6%, 71.86%, 44.44%, 12%, 53.4%, 10.83%, respectively. Many (> 64%) received preconceptual care at specialist gynecology offices. Results demonstrated that health literacy had a statistically significant relationship with preconceptual care, folic acid consumption, exercise and dental care, (p < 0.001), along with blood testing and Pap smear testing (p < 0.05).

CONCLUSION

Overall, our results demonstrate that despite health literacy being optimal, uptakes of some components of preconceptual care are low. As such, it will be important to further raise awareness of the importance of preconceptual care for people prior to pregnancy as a priority in health promotion and education.

Mediating role of health literacy in relationship between frailty and health-related quality of life in community-dwelling older adults

PURPOSE

The aim of this study was to investigate the mediating effects of health literacy on the relationship between frailty and health-related quality of life (HRQOL) among community-dwelling older adults.

METHODS

This study used the Korean Frailty and Aging Cohort Database (KFACD) for secondary data analysis. We selected data from 1,631 people without missing main variable values for analysis. Frailty was determined based on the modified Fried's phenotype [MFP], and HRQOL was measured using the Korean version of the 5-level EuroQol questionnaire (EQ-5D-5L). Health literacy was assessed using the questions on the Behavioral Risk Factor Surveillance System (BRFSS) used by the U.S. Center for Disease Control and Prevention. To examine the mediating role of health literacy in the relationship between frailty and HRQOL, Baron & Kenny's three-step mediating effect verification method was utilized.

RESULTS

The participants had a mean frailty score of 1.37±1.02, health literacy score of 8.56±2.59, and HRQOL score of 0.84±0.10. Frailty was negatively correlated with health literacy (r = -0.27, p < .001) and HRQOL (r = -0.32, p < .001), while health literacy was positively correlated with HRQOL (r = 0.34, p < .001). We observed that health literacy played a partial mediating role in the relationship between frailty and HRQOL.

CONCLUSION

To increase older adults' HRQOL, measures that directly prevent and manage frailty as well as interventions that target the enhancement of health literacy are needed.

Cross-sectional and Correlational Examination of Patients' Preoperative Anxiety, Information Need, and Health Literacy in a Presurgical Consultation

PURPOSE

This study elucidates the preoperative anxiety (PA), information need (IN), and health literacy (HL) levels of an elective preoperative sample in Switzerland and examines the possible associations between PA and the patients' characteristics. By knowing these patient dimensions, which can influence perioperative outcomes, one can tailor individualized nursing interventions to improve patients' surgical experience.

DESIGN

This was a cross-sectional and correlational study.

METHODS

The sample consisted of 88 patients who underwent a preoperative consultation at a Swiss tertiary hosptial. Patients' PA and IN were assessed using the Anxiety Preoperative and Information Scale, and their HL was measured using the Functional, Communicative, and Critical Health Literacy Scale. Data on other patient characteristics were collected from the patients, physicians, and electronic patient records. Association tests, as well as univariate regressions, were performed on PA, IN, HL, and patient characteristics.

FINDINGS

Among participants, 40.91%, 78.41%, and 59% reported having PA, IN, and low HL, respectively. Finally, PA was associated with IN, HL, solitary living, and the American Society of Anesthesiology score.

CONCLUSIONS

A high proportion of patients scheduled for presurgical consultation were found to be anxious. They presented high IN and low HL. An examination of patients' PA-associated characteristics can help improve their surgical experience. More studies should examine PA-associated characteristics.

Examining Communicative, Critical Health Literacy and eHealth Literacy among International University Students Residing in Japan

(1) Background: International students with sufficient health literacy are better equipped to respond to public health emergencies and reduce any unintentional harm that may occur during such events. This study aims to assess the current status of health literacy among international students and investigate the factors that influence health literacy. (2) Methods: A cross-sectional study was conducted in Tokyo on international university students using a questionnaire consisting of the Communicative and Critical Health Literacy and eHealth Literacy Scales. The study analyzed 205 valid responses. Descriptive statistics were utilized to assess the level of health literacy, and linear regression was used to identify the association of socio-demographic characteristics and disease status with health and e-health literacy. (3) Results: Health literacy and e-health literacy were low in 48.29% and 47.29% of international students, respectively. The mean scores of CCHL items ranged from 3.13 to 3.26, while the mean scores of eHEALS items ranged from 3.33 to 3.49. Both health literacy and e-health literacy were better with unmarried status (p = 0.015), and e-health literacy was worse with higher age (p = 0.007). (4) Conclusions: Overall, international students' health literacy and e-health literacy were at intermediate levels, with considerable room for improvement, and affected by certain student attributes.

Health literacy and its association with mental and spiritual well-being among women experiencing homelessness

Low health literacy (HL) has been linked to low self-rated health, reduced efficacy of behaviour change, and challenges in preventing, treating, or managing health conditions. People experiencing homelessness are at risk of poor HL; however, few studies have investigated HL in relation to mental and spiritual well-being among people experiencing homelessness in general, or women experiencing homelessness specifically. This cross-sectional study of 46 women experiencing homelessness in Stockholm, Sweden, recruited during the period October 2019-December 2020, aimed to examine how HL was associated with mental and spiritual well-being among women experiencing homelessness. Participants answered questions about socio-demographic characteristics (age, length of homelessness, education) and digital technology (mobile phone/the Internet) use, in addition to Swedish language versions of three questionnaires administered through structured, face-to-face interviews: the Communicative and Critical Health Literacy Scale, the General Health Questionnaire 12 and the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being. Data were analysed using linear regression, which revealed statistically significant associations between HL and mental well-being (p = .009), and between HL and spiritual well-being (p = .022). However, neither socio-demographic characteristics nor digital technology use were significantly associated with HL. In conclusion, promoting HL may improve mental and spiritual well-being in this vulnerable population. An advisory board of women with lived experiences of homelessness (n = 5) supported the interpretation of the findings and emphasised the need to consider HL in relation to basic needs such as 'housing first'. Moreover, health information and services should be accessible to people with different degrees of HL.

Prevalence and Correlates of Dietary and Nutrition Information Seeking Through Various Web-Based and Offline Media Sources Among Japanese Adults: Web-Based Cross-Sectional Study

BACKGROUND

The advent of the internet has changed the landscape of available nutrition information. However, little is known about people's information-seeking behavior toward healthy eating and its potential consequences.

OBJECTIVE

We aimed to examine the prevalence and correlates of nutrition information seeking from various web-based and offline media sources.

METHODS

This cross-sectional study included 5998 Japanese adults aged 20 to 79 years participating in a web-based questionnaire survey (February and March 2023). The dependent variable was the regular use of web-based and offline media as a reliable source of nutrition information. The main independent variables included health literacy, food literacy, and diet quality, which were assessed using validated tools, as well as sociodemographic factors (sex, age, education level, and nutrition- and health-related occupations).

RESULTS

The top source of nutrition information was television (1973/5998, 32.89%), followed by web searches (1333/5998, 22.22%), websites of government and medical manufacturers (997/5998, 16.62%), newspapers (901/5998, 15.02%), books and magazines (697/5998, 11.62%), and video sites (eg, YouTube; 634/5998, 10.57%). Multivariable logistic regression showed that higher health literacy was associated with higher odds of using all the individual sources examined; odds ratios (ORs) for 1-point score increase ranged from 1.27 (95% CI 1.09-1.49) to 1.81 (95% CI 1.57-2.09). By contrast, food literacy was inversely associated with the use of television (OR 0.65, 95% CI 0.55-0.77), whereas it was positively associated with the use of websites of government and medical manufacturers (OR 1.98, 95% CI 1.62-2.44), books and magazines (OR 2.09, 95% CI 1.64-2.66), and video sites (OR 1.53, 95% CI 1.19-1.96). Furthermore, diet quality was positively associated with the use of newspapers (OR 1.02, 95% CI 1.01-1.03) and books and magazines (OR 1.03, 95% CI 1.02-1.04). Being female was associated with using television and books and magazines, whereas being male was associated with using websites of government and medical manufacturers, newspapers, and video sites. Age was positively associated with using newspapers and inversely associated with using websites of government and medical manufacturers and video sites. People with higher education were more likely to refer to websites of government and medical manufacturers and newspapers but less likely to use television and video sites. Dietitians were more likely to use websites of government and medical manufacturers and books and magazines than the general public but less likely to use television and video sites.

CONCLUSIONS

We identified various web-based and offline media sources regularly used by Japanese adults when seeking nutrition information, and their correlates varied widely. A lack of positive associations between the use of the top 2 major sources (television and web searches) and food literacy or diet quality is highlighted. These findings provide useful insights into the potential for developing and disseminating evidence-based health promotion materials.

A Community-Based Intervention to Enhance Subjective Well-Being in Older Adults: Study Design and Baseline Participant Profiles

Promoting subjective well-being is a crucial challenge in aging societies. In 2022, we launched a community-based intervention trial (the Chofu-Digital-Choju Movement). This initiative centered on fostering in-person and online social connections to enhance the subjective well-being of older adults. This paper describes the study design and baseline survey. This quasi-experimental study involved community-dwelling older adults aged 65-84 years in Chofu City, Tokyo, Japan. A self-administered questionnaire was distributed to 3742 residents (1681 men and 2061 women), and a baseline survey was conducted in January 2022. We assessed subjective well-being (primary outcome); psychosocial, physical, and dietary factors; and the use of information and communication technology variables (secondary outcomes) among the participants. After the intervention involving online classes, community hubs, and community events, a 2-year follow-up survey will be conducted to evaluate the effects of the intervention, comparing the intervention group (participants) with the control group (non-participants). We received 2503 questionnaires (66.9% response rate); of these, the analysis included 2343 questionnaires (62.6% valid response rate; mean age, 74.4 (standard deviation, 5.4) years; 43.7% male). The mean subjective well-being score was 7.2 (standard deviation, 1.9). This study will contribute to the development of a prototype subjective well-being strategy for older adults.

Does health literacy influence health-related lifestyle behaviors among specialists of health management? A cross-sectional study

BACKGROUND

Noncommunicable diseases (NCDs), such as health-related lifestyle diseases, are the leading cause of mortality and societal and economic burdens. Poor lifestyle behaviors, which are modifiable to improve health, can cause diseases, including NCDs. Health literacy has been recognized as an important determinant of health, and studies have shown that higher health literacy is associated with better health outcomes and positive health-related behaviors. However, few studies have investigated the association between health literacy and health-related lifestyle behaviors to understand the mechanistic link between them. Thus, this study investigated the extent to which health literacy at different levels influences health-related lifestyle behaviors.

METHODS

A cross-sectional study was conducted among Japanese health management specialists (N = 1,920). Functional, critical, and communicative health literacy were measured. Lifestyle behaviors (exercise, diet and nutrition, sleep, rest, smoking, and alcohol intake), in line with the Japanese National Health Promotion Program, were assessed and calculated into a total cumulative score of health-related lifestyle behaviors. Moreover, we analyzed the associations between the three levels of health literacy and lifestyle behaviors using regression analyses by adjusting for socio-psycho-demographic factors.

RESULTS

Multiple linear regression analyses showed a significant association between the Japanese version of the European Health Literacy Survey Questionnaire and total health-related lifestyle scores (standardized β = 0.160, p < 0.001, R2 = 0.136) after adjusting for sociodemographic factors. Similarly, the association between communicative and critical health literacy and the total health-related lifestyle scores was significant (standardized β = 0.122, p < 0.001, R2 = 0.125). The analysis indicated that individuals who had higher level of health literacy (critical and communicative) than functional health literacy (Japanese version of the Newest Vital Sign score) had higher health-related lifestyle behaviors.

CONCLUSIONS

A higher level of health literacy is associated with health-related lifestyle behaviors. Health literacy can be a target for interventions to achieve the national goal of lifestyle-related disease prevention and control.

Relationship between a gum-chewing routine and oral, physical, and cognitive functions of community-dwelling older adults: A Kashiwa cohort study

AIM

As associations between oral function and general health have been reported in community-dwelling older adults, easily implementable preventive measures are urgently required. We focused on the health benefits of gum chewing, as no studies have been carried out on the impact of gum-chewing routines on the health of older adults. This cross-sectional study aimed to determine whether the gum-chewing routine is associated with oral, physical and cognitive functions in community-dwelling older adults.

METHODS

This study included 1617 community-dwelling older participants in a health survey carried out in 2021. The gum-chewing routine and weekly chewing time were assessed using a self-administered questionnaire. The outcome measures, including actual measurements of oral function, physical function, cognitive function, dietary intake and lifestyle, were evaluated using self-administered questionnaires or health surveys.

RESULTS

We analyzed 1474 (mean age 76.1 ± 5.8 years, 45% women) participants for whom all data were not missing, and 14% of them had a gum-chewing routine for more than 30 min weekly. Oral functions were significantly higher in older adults with a gum-chewing routine, and there were substantially fewer participants with oral frailty (adjusted odds ratio 0.581, 95% confidence interval 0.340-0.993). Additionally, cognitive and physical functions, including grip strength, were significantly higher in the gum-chewing routine group.

CONCLUSIONS

Community-dwelling older adults with a gum-chewing routine have higher oral, physical and cognitive functions. These findings indicate that a gum-chewing routine might contribute to maintaining oral function and preventing frailty. Geriatr Gerontol Int 2024; 24: 68-74.

Anemia-related subjective symptoms in the general adult population in Japan

Objectives: Approximately 17% of Japanese women have hemoglobin concentrations less than 12 g/dL. Therefore, anemia prevention and early intervention are crucial public health issues in Japan. This study aimed to identify the symptoms and characteristics of anemic individuals in the general adult population by comparing survey responses of individuals with anemia and without anemia visiting blood donation centers. Materials and Methods: This cross-sectional study used self-administered questionnaires. Individuals who visited two Japanese Red Cross Society blood donation centers in Fukushima Prefecture, Japan were included. Hemoglobin levels were measured at blood donation, and the levels of 13 g/dL for men and 12 g/dL for women were defined as anemia. Results: Of the 857 individuals analyzed, 530 were men and 327 were women, of whom 19 (3.6%) and 12 (3.7%) had low hemoglobin levels, respectively. Logistic regression analysis was performed in men, and the results showed that "lightheadedness" (odds ratio [OR]=8.4) and "depressive symptoms" (OR=3.6) were significantly associated with hemoglobin levels. None of the evaluated items were significantly associated with hemoglobin levels in women. Conclusion: Among healthy Japanese men, those who exhibit lightheadedness and depressive symptoms have an increased risk of anemia. Lightheadedness and depressive symptoms may be indicative of undiagnosed anemia in men, which necessitates greater clinical attention.

Age, gender and socioeconomic disparities in human papillomavirus (HPV) awareness and knowledge among Japanese adults after a 7-year suspension of proactive recommendation for the HPV vaccine: A nationally representative cross-sectional survey

The Japanese government's 2013 suspension of its proactive recommendation for Human papillomavirus (HPV) vaccination resulted in low HPV vaccination coverage and was unique. However, data on awareness and knowledge of HPV vaccines in the general population was limited. Here, to investigate more recent awareness and knowledge of HPV vaccines by age, gender, and socioeconomic status, we used data from the INFORM Study 2020, a nationally representative cross-sectional survey of self-administered questionnaires with 1,998 Japanese individuals aged 20 to 59 years. We found that 47.5% of females and 21.0% of males had heard of HPV, and 33.6% of females and 16.8% of males had knowledge of HPV vaccine efficacy. After adjusting for potential confounders, females aged 50-54 years were more likely to be aware of HPV than females aged 20-24 (AOR, 2.02, 95%CI: 1.12-3.65). Females (AOR, 2.13, 95%CI: 1.48-3.07) and males (AOR, 1.64, 95%CI: 1.03-2.59) with higher education had more awareness than those with less education. Females with higher education had more knowledge about HPV vaccine efficacy than those with less education (AOR, 1.70; 95%CI: 1.16-2.50). We found a generally low level of awareness and knowledge about HPV vaccines in Japan, which might be attributable to the suspension of proactive recommendations. Additionally, we identified disparities in awareness and knowledge by age, gender, socioeconomic status, and health literacy. Enhancing HPV awareness and understanding of HPV vaccines and implementing targeted efforts for specific subpopulations within Japan after the resumption of proactive recommendation for HPV vaccines, are imperative.

Coping With Women's Menstruation-Related Health Issues in Male-Dominated Companies: A Cross-Sectional Study in Japan

BACKGROUND AND OBJECTIVES

Japanese women face many female-specific health problems in the workplace, especially menstruation-related issues, which can adversely affect their quality of life and productivity. This study aims to examine how female employees in a male-dominated company in Hiroshima, Japan, cope with menstruation-related health issues in the workplace and the factors that influence their coping strategies.

MATERIALS AND METHODS

This study used a cross-sectional survey research method. The survey investigated age, health, and menstrual-related issues, as well as women's active participation support and health literacy (HL) levels. The sample population included employees of a manufacturer in Hiroshima prefecture. The data were collected from February 20 to March 10, 2023. The analysis subjects were 171 women who had experienced menstruation-related, women-specific health issues in the workplace. Their attitudes toward menstruation-related issues could influence their experiences. They were categorized into positive and negative groups based on their attitudes toward coping with women's health issues. Chi-square tests and logistic regression analysis were used to compare the two groups.

RESULTS

The study found that 50.3% (N = 296) of female employees had experienced women's menstruation-related health issues at work. As many as 62.6% (N = 171) of female employees showed a positive attitude, and the study also found that female employees with a positive attitude toward menstruation-related health issues had higher HL (odds ratio (OR) = 1.216, 95% CI: 1.007-0.1.468) and were more likely to be able to predict menstruations (OR = 4.528, 95% CI: 1.618-12.670).  Conclusions: In male-dominated companies, many female employees are affected by menstruation-related problems in the workplace. A positive attitude toward women's health issues was positively associated with HL and predictive ability. Male-dominated companies should pay attention to women's menstruation-related health issues in the workplace, implement interventions to improve their health literacy and predictive ability, strengthen communication with them, and encourage them to actively participate in women's health initiatives.

Association between cultural capital and health literacy during the COVID-19 pandemic among community residents in China: the mediating effect of social capital

Background

Health literacy is crucial for managing pandemics such as COVID-19 and maintaining the health of the population; our goal was to investigate the impact of cultural capital on health literacy during the COVID-19 pandemic among community residents and to further examine the mediating role of social capital in the relationship between cultural capital and health literacy.

Methods

A cross-sectional study was conducted among 1,600 community residents selected in Chongqing, China using a stratified random sampling method. Data were gathered through a questionnaire survey, including sociodemographic characteristics, cultural capital, social capital, and health literacy. Chi-square analysis, one-way ANOVA, t-test, and hierarchical linear regression were used to analyze the level of health literacy among community residents and the related elements; the structural equation model (SEM) was used to explore the influential mechanisms of health literacy and explore whether social capital acted as a mediator in the relationship between cultural capital and health literacy.

Results

Cultural capital, community participation, community trust, reciprocity, and cognitive social capital had a significant positive effect on health literacy. In addition, the results of SEM indicated that cultural capital not only directly influences health literacy (β = 0.383, 95% CI = 0.265-0.648), but also indirectly influences health literacy through three types of social capital (β = 0.175, 95% CI = 0.117-0.465; β = 0.191, 95% CI = 0.111-0.406; β = 0.028, 95% CI = 0.031-0.174); its mediating effect accounting for 50.7% of the overall effect.

Conclusions

Our results highlight the empirical link between cultural capital and health literacy, and suggest that social capital mediates this connection. These findings suggest that governments and communities should focus on the construction of community cultural capital and provide residents with better social capital to improve their health literacy to prepare for future pandemics.

Relationship between health literacy and attitudes toward acupuncture: A web-based cross-sectional survey with a panel of Japanese residents

The relationship between health literacy of Japanese people, their attitudes toward acupuncture, and their behavior in choosing this therapy is currently unclear. Therefore, for this study, we conducted a web-based survey to address this unknown relationship. A questionnaire comprising four categories (health status, health literacy, previous acupuncture experience, and attitudes toward acupuncture) was administered to 1,600 Japanese participants. For this study, we performed cross-tabulation and path analysis to examine the relationship between each questionnaire item. The mean score of participants' health literacy was 3.41 (SD = 0.74), and older, educated, female participants tended to have higher health literacy. The respondents perceived acupuncture to be effective for chronic low back pain, tension-type headache, and knee pain due to osteoarthritis (40.0%, 38.7%, and 21.8%, respectively). Contrastingly, acupuncture was perceived as far less effective for postoperative nausea/vomiting and prostatitis symptoms (8.3% and 8.7%, respectively). Of the total study respondents, 34.4% reported that they would try acupuncture only if recommended by clinical practice guidelines, and 35.6% agreed that acupuncture is safe. The path analysis showed that attitudes toward acupuncture were significantly influenced by the participants' health literacy, number of information sources, and previous acupuncture experience. However, it was also found that experience with acupuncture was not directly associated with health literacy. Although the Japanese population with higher health literacy is more likely to perceive acupuncture positively, they do not necessarily have sufficient relevant knowledge of the clinical evidence. Therefore, their decision to receive acupuncture may be more dependent on personal narratives rather than clinical evidence. Thus, future challenges lie in individual education of the population on how to choose a reliable health information source, and organizational efforts to provide more reliable health information.

Factors associated with the status of usual source of care during the COVID-19 pandemic: a nationwide survey in Japan

BACKGROUND

To ensure that high-quality primary care is available to every individual, increasing the proportion of residents with a usual source of care (USC) is a challenge for each country. However, the status of USC after the spread of COVID-19 and the factors associated with it remain unclear internationally. Therefore, we aimed to explore the associations of sociodemographic and clinical factors with the presence and type of USC (kakaritsukei in Japanese) during the pandemic in Japan.

METHODS

We conducted a nationwide cross-sectional survey of a representative sample of the general Japanese adult population in May 2021. The main outcome measures were the presence and type of USC. We assessed sociodemographic and clinical factors, including age, gender, marital status, years of education, employment status, annual household income, social isolation, health literacy, number of chronic conditions, and health-related quality of life.

RESULTS

Of the 1,757 participants, 1,011 (57.5%) had a USC. There were 769 (76.1%) participants who had a USC in a clinic and 227 (22.5%) in a hospital. As a result of multivariable modified Poisson regression analysis, male gender, no chronic condition, lower health literacy, and social isolation were significantly associated with not having a USC. Among participants with a USC, male gender, the presence of one or more chronic conditions, and lower health-related quality of life were associated with having a hospital-based USC.

CONCLUSIONS

We identified factors associated with the status of USC during the COVID-19 pandemic, including health literacy and social isolation. These findings provide primary care providers and policymakers with insight into the potential barriers to having a USC in the aftermath of the pandemic.

General health literacy, COVID-19-related health literacy, and protective behaviors: evidence from a population-based study in Japan

Introduction

Health literacy (HL) can be regarded as a key element of non-pharmaceutical interventions used in emergency responses. The present study aimed to determine the associations of combinations of general HL and COVID-19-related HL with COVID-19 protective behaviors and healthy lifestyle behaviors.

Methods

A questionnaire survey was conducted from December 2020 to January 2021 among residents in Japanese metropolitan areas. Valid responses were received from 1,443 residents. The levels of HL were categorized into four groups: low level in both HLs (reference), high level in general HL only, high level in COVID-19-related HL only, and high level in both HLs. The total scores of eight COVID-19 protective behaviors were dichotomized into low and high adherence. Healthy lifestyle behaviors included healthy and balanced diet, adequate sleep, and regular exercise. Poisson regression analyses were conducted to examine the associations between the HL groups and high adherence to COVID-19 protective behaviors.

Results

High level in COVID-19-related HL only was associated with high adherence to COVID-19 protective behaviors [prevalence ratio (PR), 1.25; 95% confidence interval (CI), 1.09-1.45], while high level in general HL only was associated with healthy and balanced diet (PR, 1.49; 95% CI, 1.04-2.13), adequate sleep (PR, 1.46; 95% CI, 1.02-2.10), and regular exercise (PR, 2.00; 95% CI, 1.29-3.13). High level in both HLs showed the highest prevalence of high adherence to COVID-19 protective behaviors and healthy lifestyle behaviors.

Conclusion

These findings indicate that COVID-19-related HL and general HL can both be considered to enhance protective behaviors.

Prevalence of cannabidiol (CBD) consumption and cancer patients' expectations in one oncology day-hospital: A cross-sectional study and questionnaire validation

INTRODUCTION

The growing interest of cannabidiol (CBD) in medical care prompted French health authorities to explore the potential of CBD in cancer-related severe symptoms. This study aimed to assess the prevalence of CBD use among cancer patients with potential associated factors and to measure the cancer patient's health literacy (HL) on CBD consumption.

METHODS

In a prospective study in oncology day-care hospital including patients from 29 October to 20 December 2021, we collected demographic, biological, and oncological characteristics. Patient CBD HL was measured by the hetero-questionnaire 8-item-CBD HL scale (HLS-8-CBD) whose conception has been validated by a psychometric analysis.

RESULTS

Among 363 participants, 20 patients (5.5%) reported CBD use. Factors associated with CBD use were: age <60 years (odd ratio = 7.80[1.36-13.32], p < 10^-4 versus ≥60 years), smoking history (OR = 5.53[1.81-16.88], p < 0.01), and no smoking cessation (OR = 5.07[1.66-15.46], p < 0.01). CBD use was also associated with a better CBD total HL score than non-users (p-value = 0.02).

CONCLUSION

Identification of factors associated with CBD use and a relatively high patient CBD HL in CBD users showed that CBD use in cancer patients care represented a new concern and should enhance health professionals to consider CBD with its associated drug-related problems.

Associations of health literacy with dental care use and oral health status in Japan

BACKGROUND

The concept of health literacy has gained prominence in the context of oral health. In Japan, curative dental care is generally under universal health coverage, while preventive dental care requires effort. We used this situation to test the hypothesis that high health literacy is associated with preventive dental care use and good oral health status, but not with curative dental care use, in Japan.

METHODS

A questionnaire survey was conducted from 2010 to 2011 among residents aged 25-50 years in Japanese metropolitan areas. Data from 3767 participants were used. Health literacy was measured using the Communicative and Critical Health Literacy Scale, and the total score was categorized into quartiles. Poisson regression analyses with robust variance estimators were conducted to examine the associations of health literacy with curative dental care use, preventive dental care use, and good oral health, adjusted for covariates.

RESULTS

The percentages of curative dental care use, preventive dental care use, and good oral health were 40.2%, 28.8%, and 74.0%, respectively. Health literacy was not associated with curative dental care use; the prevalence ratio (PR) of the highest relative to the lowest quartile of health literacy was 1.04 (95% confidence interval [CI], 0.93-1.18). High health literacy was associated with preventive dental care use and good oral health; the corresponding PRs were 1.17 (95% CI, 1.00-1.36) and 1.09 (95% CI, 1.03-1.15), respectively.

CONCLUSIONS

These findings may provide clues for the design of effective interventions to promote preventive dental care use and improve oral health status.

Association between trust in COVID-19 information sources and engaging in infection prevention behaviors in Japan: A longitudinal study

OBJECTIVE

We examined changes in people's trust in information sources in Japan during the COVID-19 pandemic over the course of 1 year and investigated longitudinal associations between trust in such sources and engaging in infection prevention behaviors.

METHODS

We conducted a longitudinal survey of Japanese populations under a declared state of emergency at two time points, August 2020 and August 2021. We surveyed sociodemographic data, seven Trust in COVID-19 information sources and six COVID-19 preventive behaviors.

RESULTS

In all, 784 participants completed the two surveys. Physicians were the most consistently trusted information source over the 1-year period. We identified three preventive behaviors that were positively associated with trust in physicians as an information source (social distancing, wearing masks, and washing hands with soap), four preventive behaviors that were positively associated with trusting infected patients (social distancing, using ventilation, wearing masks, and using hand sanitizer), and one preventative behavior that was negatively associated with trust in government (avoiding closed spaces).

CONCLUSION

In the ongoing pandemic, information from physicians and patients may encourage people to engage in long-term preventive behaviors.

PRACTICE IMPLICATIONS

Physicians and patients should be promoted as trusted and behavior influencing sources of information during the pandemic.

Effect modification by geographic area on the association between health literacy and self-rated health: a nationwide cross-sectional study in Japan

BACKGROUND

Health literacy (HL) has gained increasing attention as a factor related to health behaviors and outcomes. This study aimed to investigate geographic differences in HL levels and effect modification by geographic area on their relationship with self-rated health in the Japanese population using a nationwide sample.

METHODS

Data for this study were derived from a nationally representative cross-sectional survey on health information access for consumers in Japan using a mailed self-administered questionnaire in 2020 (INFORM Study 2020). Valid responses from 3,511 survey participants, selected using two-stage stratified random sampling, were analyzed in this study. HL was measured using the Communicative and Critical Health Literacy Scale (CCHL). Multiple regression and logistic regression analyses were conducted to examine the associations between geographic characteristics and HL and effect modification on the association between HL and self-rated health by geographic area, controlling for sociodemographic characteristics.

RESULTS

The mean HL score was 3.45 (SD = 0.78), somewhat lower compared with previous studies on the Japanese general population. HL was higher in Kanto area than in Chubu area, after controlling for sociodemographic factors and municipality size. Furthermore, HL was positively associated with self-rated health after controlling for sociodemographic and geographic factors; however, this association was more evident in eastern areas than in western areas.

CONCLUSION

The findings indicate geographic differences in HL levels and effect modification by geographic area on the relationship between HL and self-rated health in the general Japanese population. HL was more strongly associated with self-rated health in eastern areas than in western areas. Further investigation is needed to explore the moderating effects of areal features, including the distribution of primary care physicians and social capital, when formulating strategies to improve HL in different contexts.

Leaflet information by the local government on mental health during the coronavirus disease 2019 pandemic: a cross-sectional study in a rural area in Japan

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic and associated infodemic increased depression and anxiety. Proper information can help combat the infodemic and promotes mental health; however, rural residents have more difficulties in getting correct information than urban residents.

OBJECTIVE

To examine whether the information on COVID-19 provided by the local government maintained the mental health of rural residents in Japan.

METHODS

A self-administered questionnaire survey of Okura Village (northern district of Japan) residents aged ≥16 years was conducted in October 2021. The main outcomes, depressive symptoms, psychological distress, and anxiety were measured using the Center for Epidemiologic Studies Depression Scale, Kessler Psychological Distress Scale, and Generalized Anxiety Disorder scale 7-item. Exposure was defined as whether the resident read the leaflet on COVID-19 distributed by the local government. The targeted maximum likelihood estimation was used to analyse the effect of leaflet reading on the main outcomes.

RESULTS

A total of 974 respondents were analysed. Reading the leaflet was significantly lower risk for depressive symptoms relative risk (95% confidence interval): 0.64 (0.43-0.95). Meanwhile, no clear effects of leaflet reading were observed on mental distress and anxiety.

CONCLUSIONS

In rural areas with local governments, analogue information may be effective to prevent depression.

Development of an action plan for acute food protein-induced enterocolitis syndrome in Japan

Reports of food protein-induced enterocolitis syndrome (FPIES) in Japan have been increasing. However, the disease itself and the treatment options are poorly understood by both patients and medical professionals. The objective of this study is to develop an action plan for acute FPIES in Japan. We prepared a single-sheet action plan that describes the management of acute FPIES episodes for caregivers on one side and medical professionals on the reverse side. To evaluate the content of the action plan, we distributed a questionnaire to caregivers of patients with FPIES and to physicians who would encounter patients with FPIES. Changes to the FPIES action plan were made based on the feedback from the participants. The Delphi method was utilized to finalize the action plan. The participants of the initial survey found the action plan to be useful but the process for determining severity to be impractical. After discussion, the authors made appropriate improvements. By the Delphi method, consensus was reached on the revised FPIES action plan. In conclusion, this Japanese FPIES action plan was created by physicians from multiple subspecialties and caregivers of patients with FPIES. The action plan may improve the management of acute FPIES reactions in the Japanese community.

Association between community-level health literacy and frailty in community-dwelling older adults

AIMS

We aimed to investigate whether high community-level health literacy, beyond individual-level health literacy, is associated with a low prevalence of frailty among community-dwelling older adults.

METHODS

A large cross-sectional questionnaire survey was conducted among citizens in Maizuru City, Kyoto, Japan, aged 65 years or older who were not certified as "support" or "care" level according to Japan's public long-term care insurance system, who could perform basic activities of daily living, and who did not have dementia or Parkinson's disease. Frailty status was assessed using the Kihon Checklist, with a score ≥ 8 indicating frailty. Health literacy was assessed using the Communicative and Critical Health Literacy Scale. The mean health literacy score of 20 school districts was used as the community-level health literacy index. We investigated demographic data and other potential confounding factors, including education, living arrangement, body mass index, comorbidity, smoking status, depressive symptoms, social networks, and community-level covariates.

RESULTS

The primary analysis included 6230 individuals (mean age = 74.3 years [SD = 6.1]). In each school district, the prevalence of frailty was 21.2-34.2% (mean: 26.2%), and community-level health literacy index was 3.1-3.5 (mean: 3.4). Multilevel logistic regression model including school district as random effect showed that the community-level health literacy was significantly associated with frailty (odds ratio [95% confidence interval] = 0.28 [0.08 to 0.96]) after adjusting for the covariates.

CONCLUSIONS

Not only high individual-level health literacy but also high community-level health literacy is associated with a low prevalence of frailty in community-dwelling older adults.

Association of health literacy with anxiety about COVID-19 under an infectious disease pandemic in Japan

We quantitatively analysed the relationship of health literacy with both anxiety about the COVID-19 outbreak and free-text qualitative data. A questionnaire was mailed to 5450 citizens aged 16-89 years in four prefectures between late April and May 2020. It gauged the level of anxiety about COVID-19, assessed health literacy (HL) on both critical and communicative HL subscales, and invited free-text responses. We compared anxiety levels in three groups of both HL subscales. Text-mining analyses were also conducted among the three HL groups. Two-thirds of respondents reported anxiety about COVID-19, and 42% of them also reported fear. The level of communicative HL was negatively associated with no or low anxiety (p < 0.01), and the same association was observed for critical HL (p < 0.01). Free-text analysis identified 11 categories related to concerns about COVID-19: response of the national government, appreciation of health care practitioners, early convergence, vaccine development, fear of infection, invisible, a school for children, everyday life, information-related issue, novel coronavirus and self-quarantine. Words that were characteristic of the high-HL group were 'information', 'going out', 'vaccines' and 'government'. This survey reveals high public anxiety under COVID-19, and while anxiety is associated with HL levels, people with higher HL may make more prudent and healthier decisions. In situations of uncertainty, different approaches to alleviate anxiety depending on HL are warranted, providing new insights and contributing to public health measures during the outbreaks.

The relationship between health literacy, knowledge, fear, and COVID-19 prevention behavior in different age groups: A Cross-sectional online study in Japan

BACKGROUND

Coronavirus disease (COVID-19) prevention behaviors have become part of our lives. COVID-19 prevention behaviors have been reported to be associated with health literacy, knowledge, and fear. However, COVID-19 pandemic may be characterized by different situations in each age group. Since the severity of the infection and the means of accessing information differ by age group, the relationship between health literacy, knowledge, and fear may differ. Thus, factors that promote preventive behavior may differ by age group. Clarifying the factors related to prevention behaviors by age may help us consider age-appropriate promotion.

OBJECTIVE

This study aimed to examine the association between COVID-19 prevention behaviors and health literacy, COVID-19 knowledge, and fear of COVID-19 by age group.

METHODS

A cross-sectional study was conducted with 512 participants aged 20-69 years, recruited from an online sample from November 1 to 5, 2021. An online self-administered questionnaire was used to obtain the participants' characteristics, COVID-19 prevention behaviors, health literacy, COVID-19 knowledge, and fear of COVID-19. The Kruskal-Wallis rank-sum test was used to compare the scores of each item for each age group. The relationships among COVID-19 prevention behaviors, health literacy, COVID-19 knowledge, and fear of COVID-19 were analyzed using Spearman's rank correlation analysis. Additionally, multiple regression analysis was conducted with COVID-19 prevention behaviors as the dependent variable; health literacy, COVID-19 knowledge, and fear of COVID-19 as independent variables; and sex and age as adjustment variables.

RESULTS

For all participants, correlation and multiple regression analyses revealed that prevention behaviors were significantly related to health literacy, COVID-19 knowledge, and fear of COVID-19 (p<.001). Additionally, correlation analysis revealed that fear of COVID-19 was significantly negatively correlated with COVID-19 knowledge (p<.001). There was also a significant positive correlation between health literacy and COVID-19 knowledge (p<.001). Furthermore, analysis by age revealed that the factors associated with prevention behaviors differed by age group. In the age group-20-29, 30-39, and 40-49 years, multiple factors, including health literacy, influenced COVID-19 prevention behaviors, whereas in the age group-50-59 and 60-69 years, only fear of COVID-19 had an impact.

CONCLUSIONS

The results of this study revealed that the factors associated with prevention behaviors differ by age. Age-specific approaches should be considered to prevent infection.

Chronic Diseases and Sociodemographic Characteristics Associated With Online Health Information Seeking and Using Social Networking Sites: Nationally Representative Cross-sectional Survey in Japan

BACKGROUND

In an aging society, worsening chronic diseases increase the burden on patients and the health care system. Using online health information including health information via social networking sites (SNSs), such as Facebook and YouTube, may play an important role in the self-management of chronic diseases and health promotion for internet users.

OBJECTIVE

This study aims to improve strategies for promoting access to reliable information for the self-management of chronic diseases via the internet, and to identify populations facing barriers to using the internet for health, we examined chronic diseases and characteristics associated with online health information seeking and the use of SNSs.

METHODS

This study used data from the INFORM Study 2020, which was a nationally representative cross-sectional postal mail survey conducted using a self-administered questionnaire in 2020. The dependent variables were online health information seeking and SNS use. Online health information seeking was assessed using 1 question about whether respondents used the internet to find health or medical information. SNS use was assessed by inquiring about the following 4 aspects: visiting SNSs, sharing health information on SNSs, writing in an online diary or blog, and watching a health-related video on YouTube. The independent variables were 8 chronic diseases. Other independent variables were sex, age, education status, work, marital status, household income, health literacy, and self-reported health status. We conducted a multivariable logistic regression model adjusted for all independent variables to examine the associations of chronic diseases and other variables with online health information seeking and SNS use.

RESULTS

The final sample for analysis comprised 2481 internet users. Hypertension or high blood pressure, chronic lung diseases, depression or anxiety disorder, and cancer were reported by 24.5%, 10.1%, 7.7%, and 7.2% of respondents, respectively. The odds ratio of online health information seeking among respondents with cancer was 2.19 (95% CI 1.47-3.27) compared with that among those without cancer, and the odds ratio among those with depression or anxiety disorder was 2.27 (95% CI 1.46-3.53) compared with that among those without. Further, the odds ratio for watching a health-related YouTube video among those with chronic lung diseases was 1.42 (95% CI 1.05-1.93) compared with that among those without these diseases. Women, younger age, higher level of education, and high health literacy were positively associated with online health information seeking and SNS use.

CONCLUSIONS

For patients with cancer, strategies for promoting access to websites with reliable cancer-related information as well as access among patients with chronic lung diseases to YouTube videos providing reliable information may be beneficial for the management of these diseases. Moreover, it is important to improve the online environment to encourage men, older adults, internet users with lower education levels, and those with low health literacy to access online health information.

The relationship between depression, anxiety, e-health literacy, and health-promoting behavior in nursing students during COVID-19

The purpose of this study was to identify the correlation between depression, anxiety, e-health literacy (eHL), and health-promoting behaviors among nursing students during the coronavirus disease 2019 (COVID-19) pandemic, and to identify the factors affecting health-promoting behaviors. A cross-sectional study was conducted online, recruiting 301 nursing students recruited from 4 universities in the Chungcheng Province and Daejeon Metropolitan City in South Korea between May 28 and June 30, 2021. Data were analyzed using SPSS WIN 27.0. The general characteristics of the study participants were analyzed by frequency and percentage, and the degree of depression, anxiety, eHL, and health-promoting behaviors were calculated as averages and standard deviations. Differences in health-promoting behaviors according to general characteristics were analyzed using independent t tests and analysis of variance, and a post hoc Scheffe test was conducted. Correlations between depression, anxiety, eHL, and health-promoting behaviors were measured using Pearson correlation matrices. Stepwise multiple regression was performed to identify factors affecting health-promoting behaviors. During the COVID-19 pandemic, the average level of depression and anxiety was reported to be 3.93 (4.71) and 3.40 (4.30), respectively; 33.2% of nursing students experienced more than mild depression and 29.2% experienced anxiety. The average eHL level was 3.91 (0.56), and the average of health-promoting behaviors was 2.43 (0.45). Depression was positively correlated with anxiety (R = 0.734, P < .001) and negatively correlated with health-promoting behaviors (r = -0.198, P = .001), whereas eHL had a positive correlation with health-promoting behaviors (R = 0.347, P < .001). The factors affecting health-promoting behaviors were religion (β = -0.160, standard error [SE] = 0.048), current health status (β = -0.097, SE = 0.032), frequency of searching the Internet for health-related information in a week (β = -0.070, SE = 0.026), interest in health (β = -0.191, SE = 0.039), and critical eHL (β = 0.243, SE = 0.040); the explanatory power was 27.4%. Results demonstrate that during the COVID-19 pandemic, higher depression and anxiety among nursing students decreased health-promoting behaviors, while higher eHL increased health-promoting behaviors, and eHL was a major factor affecting health-promoting behaviors. These results contribute to the provision of basic data for the development of nursing intervention programs and educational strategies that can establish correct health-promoting behaviors by managing depression and anxiety among nursing students and improving eHL.

Amazon Amandaba-Sociodemographic Factors, Health Literacy, Biochemical Parameters and Self-Care as Predictors in Patients with Type 2 Diabetes Mellitus: A Cross-Sectional Study

BACKGROUND

Health literacy (HL) and its domains (functional, critical, and communicative) appear to be related to self-care adherence in people with type 2 diabetes mellitus (DM2). This study aimed to verify if sociodemographic variables are predictors of HL, if HL and the sociodemographic factors affect biochemical parameters together, and if HL domains are predictors of self-care in DM2.

METHODS

We used the baseline assessment data from 199 participants ≥ 30 years in the project, "Amandaba na Amazônia: Culture Circles as a Strategy to Encourage Self-care for DM in Primary Health Care," which took place in November and December 2021.

RESULTS

In the HL predictor analysis, women (p = 0.024) and higher education (p = 0.005) were predictors of better functional HL. The predictors of biochemical parameters were: glycated hemoglobin control with low critical HL (p = 0.008); total cholesterol control with female sex (p = 0.004), and low critical HL (p = 0.024); low-density lipoprotein control with female sex (p = 0.027), and low critical HL (p = 0.007); high-density lipoprotein control with female sex (p = 0.001); triglyceride control with low Functional HL (p = 0.039); high levels of microalbuminuria with female sex (p = 0.014). A low critical HL was a predictor of a lower specific diet (p = 0.002) and a low total HL of low medication care (p = 0.027) in analyses of HL domains as predictors of self-care.

CONCLUSION

Sociodemographic factors can be used to predict HL, and HL can predict biochemical parameters and self-care.

Relationship between the Effects of Perceived Damage Caused by Harmful Rumors about Fukushima after the Nuclear Accident and Information Sources and Media

The nuclear accident that accompanied the Great East Japan Earthquake of 11 March, 2011, was also an information disaster. A serious problem that arose after the accident and persisted for a long time was the damage caused by harmful rumors (DCBHR). In 2016, a cross-sectional questionnaire survey on health and information was conducted in Fukushima. The eligible population of this survey was 2000 Fukushima residents, which included those in the evacuated areas. We received 861 responses. Data were analyzed using the responses to the question about perceived DCBHR as the objective variable and the sources of information residents trusted and the media they used as explanatory variables. A multiple logistic regression analysis revealed that those who trusted government ministries and local commercial TV were significantly associated with no effect. In contrast, those who used Internet sites and blogs were significantly associated with a negative effect. This study underlines the pivotal importance of media and information, literacy, and education and discusses how these should be improved to avoid DCBHR in the future. Furthermore, accurate information should be made available to all sections of the population to diminish DCBHR.

Associations between Vaccination Behavior and Trust in Information Sources Regarding COVID-19 Vaccines under Emergency Approval in Japan: A Cross-Sectional Study

We examined the association between COVID-19 vaccination behavior and trust in COVID-19-related information sources during the initial period of COVID-19 vaccination in Japan. A cross-sectional survey was conducted in August 2021, 5 months after the start of COVID-19 vaccination for the general public under emergency approval. Participants were recruited using non-probability quota sampling from among Japanese residents who were under a declared state of emergency. Sociodemographic data, vaccination behavior, and levels of trust in eight media sources of information and three interpersonal information sources were assessed using an online survey form. A total of 784 participants completed the survey. The results of multiple logistic regression analysis showed that age, household income, underlying medical conditions, and living with family were significantly associated with COVID-19 vaccination behavior. Regarding COVID-19 vaccine information sources, trust in public health experts as a source of media information and primary care physicians as a source of interpersonal information showed significantly positive associations with COVID-19 vaccination behavior (odds ratio [OR] = 1.157, 95% confidence interval [CI] 1.017-1.31; OR = 1.076; 95% CI 1.006-1.150, respectively). Increasing trust in public health experts and primary care physicians and disseminating vaccine information from these sources will help promote vaccination under emergency approval.

Does health literacy moderate the psychological pathways of physical activity from guideline awareness to behavior? A multi-group structural equation modeling

BACKGROUND

Awareness, knowledge, beliefs, and behavioral intentions of physical activity (PA) guidelines may be important mediating factors for promoting PA. However, these pathways of the psychological process to PA behavior have not been examined. These pathways may differ depending on health literacy levels. This study investigated the pathways to PA, from guideline awareness to behavior, and further examined whether they differed by health literacy.

METHODS

A cross-sectional study was conducted with 7,000 Japanese participants aged 20-69 years. The participants were registered with an Internet survey company. Participants' awareness, knowledge, beliefs, and behavioral intentions regarding the PA guidelines of Japan, the volume of moderate-to-vigorous intensity PA, activity level, and health literacy were examined through a questionnaire. The PA pathways, from guideline awareness to behavior, were examined by structural equation modeling (SEM), with PA behavior as the dependent variable. Multi-group SEM was conducted to examine the moderating effect of health literacy on PA pathways. Health literacy scores were dichotomized into high and low groups in multi-group modeling by the median split.

RESULTS

SEM revealed that PA guideline awareness directly affects PA behavior and has certain indirect effects through the mediation of knowledge, beliefs, and behavioral intentions. Furthermore, the multi-group SEM showed that the proportion of indirect effects (path coefficient [PC]: 0.11, 95% confidence interval [CI]: 0.10-0.13) was higher than direct effects (PC: 0.07, 95%CI: 0.03-0.11) in the high-health literacy group. In contrast, the proportion of direct effects (PC: 0.22, 95%CI: 0.15-0.30) was higher than indirect effects (PC: 0.06, 95%CI: 0.05-0.07) in the low-health literacy group.

CONCLUSIONS

PA guideline awareness is both directly and indirectly associated with PA behavior, mediated by psychological pathways of knowledge, beliefs, and behavioral intentions, and influenced by health literacy. These results suggest that health literacy should be considered when implementing PA guideline-based interventions.

Economic, cognitive, and social paths of education to health-related behaviors: evidence from a population-based study in Japan

BACKGROUND

There is substantial evidence on the association between lower education and unhealthy behaviors. However, the mechanism underlying this association remains unclear. This study aimed to examine whether income, health literacy, and social support mediate the association between education and health-related behaviors.

METHODS

A questionnaire survey was conducted in metropolitan areas in Japan from 2010 to 2011 among residents aged 25-50 years. Data from 3663 participants were used in this study. Health literacy was measured using the Communicative and Critical Health Literacy scale. Health-related behaviors were current smoking, poor dietary habits, hazardous drinking, and lack of exercise. Poisson regression analyses with robust variance estimators were conducted to examine the associations between education and these health-related behaviors. Multiple mediation analyses were conducted to estimate the magnitudes of the mediating effects of income, health literacy, and social support on these associations.

RESULTS

Less educated participants had higher risks of all unhealthy behaviors. Income mediated the associations of education with smoking (6.4%) and exercise (20.0%). Health literacy mediated the associations of education with dietary habits (15.4%) and exercise (16.1%). Social support mediated the associations of education with dietary habits (6.4%) and exercise (7.6%). The education-drinking association was mediated by income in the opposite direction (-10.0%). The proportions of the total effects mediated by income, health literacy, and social support were 9.8% for smoking, 24.0% for dietary habits, -3.0% for drinking, and 43.7% for exercise.

CONCLUSIONS

These findings may provide clues for designing effective interventions to reduce educational inequalities in health-related behaviors.

Impact of genomic literacy components on genetic testing decision-making in the general Japanese population in the 20s and 30s

In promoting genomic medicine, genomic literacy, which is the public's ability to acquire and utilize the knowledge and skills related to genetics and genomes, requires urgent improvement. This study determined how the three components of genomic literacy (genetic/genomic knowledge, health numeracy, and interactive and critical health literacy) are associated with risk and benefit perception for genetic testing and decision-making related to genetic testing. Using an online questionnaire, we surveyed genetic/genomic knowledge, health numeracy, interactive and critical health literacy, risk and benefit perception of genetic testing, and intention toward genetic testing of 857 Japanese citizens (aged 20-39). A vignette was created to measure the intention toward genetic testing, and respondents were asked about their willingness to undergo genetic testing and to share the results with their partners and children. The path analysis, which was done by creating a path diagram revealing the relationship of the three components with risk and benefit perception, revealed that genetic and genomic knowledge and interactive and critical health literacy affected the respondents' intention to undergo genetic testing via recognition of the benefits of such testing. Further, it was suggested that health numeracy affects benefit perception through risk perception toward genetic testing. However, the goodness of fit of this model for the intention of conveying positive results to partners and children was relatively low, thus indicating that the hypothetical model needs to be reexamined.

Association of Health Literacy With the Prevalence of Cardiovascular Diseases and Their Risk Factors Among Older Japanese Health Management Specialists

In this study, we aimed to determine the association between health literacy and the development of cardiovascular diseases (CVDs), among an older population. This cross-sectional study was conducted among Japanese health management specialists (N = 593). Higher levels (communicative and critical) of health literacy and CVD risk factors (diabetes mellitus, hypertension, dyslipidemia, and obesity) were measured. The mean patient age was 71.3 years. Logistic regression analyses showed statistically significant associations between higher levels of health literacy and the prevalence of CVDs (β coefficient = -.091, p < .05) and metabolic risk factors (β coefficient = -.084, p < .01). There was a statistically significant association between health literacy and the count of CVDs (and its risk factors) (β coefficients of Poisson regression = -.036, p < .05). The results show health literacy to be fundamentally related to low prevalence of cardiovascular diseases and their associated metabolic risk factors.

Determinants of Changes in the Diet Quality of Japanese Adults during the Coronavirus Disease 2019 Pandemic

This study evaluated changes in diet quality during the coronavirus disease 2019 (COVID-19) pandemic and its association with variations in attitudes or behavior, as well as health status changes. Participants were Japanese adults aged 20-69 years who resided in 13 prefectures where specific cautions were announced to prevent the spread of the virus. An online survey was conducted in September 2021, and participants were those who shopped for food or prepared meals more than twice a week during the survey. Overall, 2101 participants were analyzed. An improved or worsened diet quality was determined based on changes in food consumption patterns, and participants were categorized into three groups (improved diet quality (IDQ), worsened diet quality (WDQ), and others). The IDQ group participants (10.2%) improved their dietary consciousness during COVID-19, cooked almost everything from ingredients, and increased their balanced meal eating frequency. However, the WDQ participants (11.1%) had worsened dietary consciousness and increased consumption of takeaway meals and alcohol but decreased balanced meal consumption. Cooking frequency changes were not independent determinants of variations in diet quality. Our results show that the diet quality changes during COVID-19 were possibly caused by changes in dietary consciousness or different levels of meal preparation practices.

Health literacy and digital health information-seeking behavior - a cross-sectional study among highly educated Swedes

BACKGROUND

The benefits of digital development in health care may be obscured by unequal opportunities to make use of digital resources. The aim of this study was to investigate the association of health literacy with I) accessing health check test results in the Patient Electronic Health Record (PAEHR), II) searching for information to better understand individual test results, and III) using the national health information online portal provided by the Swedish national health care system.

METHODS

This cross-sectional study included data from 434 individuals, 50-64 years old, randomly selected from the Swedish population during the year 2017 to a cohort study including health examination and a web-based survey. Health literacy was assessed at baseline using the Swedish Communicative and Critical Health Literacy scale. Digital information outcomes were assessed after three months. Adjusted odds ratios (ORs) and 95% confidence intervals (CI) for the separate outcomes were computed using logistic regression. Covariates included sex, age, education, country of birth, cardiovascular risk factors at baseline, general health, risk perception, referral, and new cardiovascular risk factors detected at health examination.

RESULTS

About a third of the participants (35%) had limited health literacy, while 65% had sufficient health literacy. Sufficient health literacy was associated with accessing the PAEHR (adjusted OR 1.81 95% CI 1.07-3.06) and use of the online national health information portal provided by the Swedish national health care system (adjusted OR 2.91 95% CI 1.13-7.52) but not with searching information to better understand individual test results (adjusted OR 1.29 0.75-2.20).

CONCLUSIONS

Individuals with limited health literacy do not access their personal health information nor search for health information on the online national health information portal provided by the Swedish national health care system to the same extent as individuals with sufficient health literacy. More research is needed about how the level of health literacy relates to differences in online health information-seeking behavior and how digital health information sources and e-health services can be designed to ensure that the entire population has equal access to trustworthy and quality-ensured health information.

Can healthcare choice be predicted using stated preference data? The role of model complexity in a discrete choice experiment about colorectal cancer screening

INTRODUCTION

The validity of discrete choice experiments (DCEs) is crucial to its usage in healthcare decision-making, but there is only a limited number of health contexts in which external validity is demonstrated. This study aims to assess the internal and external validity of the DCE in the context of colorectal cancer (CRC) screening, and gather insights into the discrepancy between stated and revealed preferences.

METHODS

Stated and revealed preferences were elicited on an individual level from Dutch residents eligible for CRC screening in a DCE and a field experiment, respectively (N = 568). To identify the determinants of CRC screening participation and their relative importance, five random utility maximisation models that varied in complexity were used. We assessed the accuracy with which the models based on stated preferences predict individual-level screening choice in a holdout task (internal validity) and in the actual screening choice (external validity). Insights into the discrepancy between stated and revealed preferences were gathered by comparing groups of respondents.

RESULTS

Our findings show high internal and external validity. Choices could be accurately predicted for 95% of the respondents in the holdout task, and 90% in the actual screening choice. When scale and preference heterogeneity were taken into account model fit improved; individual-level prediction accuracy slightly increased for the holdout task but not for the actual screening choice. Respondents for whom stated preferences matched revealed preferences were generally in better health and found the GP's support for their screening decision more important.

DISCUSSION

Evidence was found that revealed preferences can be predicted accurately on an individual level. Incorporating heterogeneity improved internal validity but not external validity. Differences between stated and revealed preferences can be attributed to respondents' health and the support of their GP. We suggest researchers to continue investigating the internal and external validity of discrete choice experiments, and the role of model complexity.

Preference Variation: Where Does Health Risk Attitude Come Into the Equation?

OBJECTIVES

Decisions about health often involve risk, and different decision makers interpret and value risk information differently. Furthermore, an individual's attitude toward health-specific risks can contribute to variation in health preferences and behavior. This study aimed to determine whether and how health-risk attitude and heterogeneity of health preferences are related.

METHODS

To study the association between health-risk attitude and preference heterogeneity, we selected 3 discrete choice experiment case studies in the health domain that included risk attributes and accounted for preference heterogeneity. Health-risk attitude was measured using the 13-item Health-Risk Attitude Scale (HRAS-13). We analyzed 2 types of heterogeneity via panel latent class analyses, namely, how health-risk attitude relates to (1) stochastic class allocation and (2) systematic preference heterogeneity.

RESULTS

Our study did not find evidence that health-risk attitude as measured by the HRAS-13 distinguishes people between classes. Nevertheless, we did find evidence that the HRAS-13 can distinguish people's preferences for risk attributes within classes. This phenomenon was more pronounced in the patient samples than in the general population sample. Moreover, we found that numeracy and health literacy did distinguish people between classes.

CONCLUSIONS

Modeling health-risk attitude as an individual characteristic underlying preference heterogeneity has the potential to improve model fit and model interpretations. Nevertheless, the results of this study highlight the need for further research into the association between health-risk attitude and preference heterogeneity beyond class membership, a different measure of health-risk attitude, and the communication of risks.

HPV vaccine intention among university students during suspension of active recommendation in Japan

In Japan, active recommendation of the human papillomavirus vaccine was withheld between 2013 and 2021 due to adverse reaction reports. This resulted in low vaccine coverage with reports from less than 1%. This study aimed to investigate if knowledge and health-belief related factors associated with vaccine intention among young adolescents with the hope that our findings may be helpful in promotion campaigns. We recruited students in four colleges and universities in Akita Prefecture from 2020 to 2021 who had never been vaccinated. A total of 318 students (male 54%, mean age 21 years) responded to a self-administered questionnaire; only 6% reported immediate vaccine intention, and 61% reported no such intention or "do not know." The correct percentages of 20-item knowledge about HPV vaccine-related morbidity, mortality, and prevention were very low regardless of gender (average males 41.4% vs. females 39.6%). Multivariable logistic regression models demonstrated that in males, higher levels of literacy, perceived susceptibility, and place for vaccination (logistical barrier) were associated with HPV vaccine intention, whereas "no need now" was associated with less intention. In females, a higher level of knowledge was significantly associated with vaccine intention, whereas "concerns of adverse effects" were associated with less intention.

Influence of LINE-Assisted Provision of Information about Human Papillomavirus and Cervical Cancer Prevention on HPV Vaccine Intention: A Randomized Controlled Trial

We conducted a prospective, randomized two-arm, parallel group, and open label trial to investigate whether the use of LINE would increase HPV vaccine intention among not completely vaccinated university students. In June 2020, we recruited students aged between 18 and 35 years from four universities in Japan. Among the 357 enrollees (female, 53%), 178 and 179 participants were randomized into the LINE and Mail groups, respectively. At baseline, within three years, vaccine intention was observed in 40% vs. 42% of participants, respectively. At the first intervention, which provided similar PDF leaflets about HPV vaccine and cervical cancer prevention, there was no significant difference in vaccine intention between the two groups. However, at the second intervention of LINE-assisted knowledge intervention for 5 days per week for 7 weeks, the LINE group had a higher proportion of vaccine intention than the no intervention group (66% vs. 44%, OR: 2.62, 95% confidence interval (CI): 1.59-4.35) in per-protocol analysis. The significance remained in the intention-to-treat analysis of multiply imputed datasets. Although LINE did not directly increase HPV vaccine intention compared to conventional posts, the LINE-assisted provision of information was effective in improving HPV vaccine intention among Japanese university and college students.

COVID-19 vaccine literacy and vaccine hesitancy among pregnant women and mothers of young children in Japan

BACKGROUND

Delays in the spread of vaccination have been recognized as an urgent public health issue in the context of the COVID-19 pandemic. Vaccine literacy (VL) is a critical determinant of vaccine uptake; however, little is known about VL among pregnant women and mothers of young children.

METHODS

We analyzed data from a nationwide, cross-sectional internet survey in Japan on VL and vaccine hesitancy, conducted with 1,639 pregnant women and 5,688 mothers of young children who had given birth after July 2019, between July 24 and August 30, 2021.

RESULTS

Vaccine hesitancy was observed in 51.1 % of pregnant women and 31.9 % of mothers of young children. The risk of vaccine hesitancy was significantly higher among pregnant women with lower interactive/critical skills (risk ratio [RR] 2.10, 95 % confidence interval [CI] 1.59, 2.78, p < 0.001), although functional skills did not significantly correlate with vaccine hesitancy. For mothers of young children, we found a significantly higher risk of vaccine hesitancy among those with low VL functional skills (RR 1.38, 95 % CI 1.19, 1.61), p < 0.001) and low interactive/critical skills (RR 1.29, 95 % CI 1.10, 1.50, p = 0.001).

CONCLUSIONS

Our findings suggest that aiding individuals to correctly evaluate vaccine-related information is critical for improving vaccine acceptance rates among both pregnant women and mothers of young children. Meanwhile, improving the comprehensibility of communication toolkits may be important for women with children but have a limited effect among pregnant women.

Investigating women’s health issues and help-seeking intentions in primary care in Japan: a cross-sectional study

Background

Many women face a variety of barriers to seeing obstetricians and gynecologists (OB/GYNs). Primary care physicians (PCPs) in Japan are not well equipped to address and adequately handle women’s health issues. Hence, opportunities for women to consult PCPs about women’s health issues are often limited during busy outpatient encounters. It is essential to explore PCP’s roles in women’s health care by examining women’s health needs in a primary care setting. The aim of the study is to describe the prevalence and distribution of women’s health issues and help-seeking intentions among women visiting a primary care clinic.

Methods

This was a cross-sectional study using a questionnaire. We included women aged 20–60 years who visited a primary care clinic for any reason. The questionnaire comprised a list of women’s health issues, the General Help Seeking Questionnaire to assess help-seeking intentions, and participants’ demographics including their reasons for visiting and regularity of OB/GYN visits.

Results

We distributed the questionnaire to 294 women and analyzed 260 valid responses. The average age of the respondents was 40.5 years old, and they had an average of 5.2 clinic visits a year. Approximately half of them (50.4%) visited for their own care. One hundred thirty-nine (53.9%) reported at least one women’s health issue, and 73.9% of them had no regular visit to an OB/GYN. The major concerns of women’s health issues included gynecological cancer screenings and menstrual problems. The distribution of help-seeking intentions for each source of care appeared to be classified into three patterns. One fifth of the women indicated high help-seeking intentions for PCPs, and a greater number of women expressed higher help-seeking intentions for PCPs when they did not regularly see an OB/GYN.

Conclusions

A significant number of women who visited a primary care clinic had a specific concern about women’s health issues, and a majority of them had not regularly visited their OB/GYN. PCPs may have an important role in providing an opportunity for women to discuss their concerns about women’s health issues as part of comprehensive care during a daily clinical encounter.

Impact of health literacy on anxiety and depressive symptoms in pregnant women in Japan during the COVID-19 pandemic

To investigate the relationships between communicative and critical health literacy (CCHL) and anxiety and depressive symptoms (ADs) in pregnant women during the coronavirus disease 2019 (COVID-19) pandemic. A cross-sectional study was conducted and 5466 pregnant women responded in Japan in September 2020. A Kessler 6 scale (K6) score ≥ 10, an Edinburgh Postnatal Depression Scale (EPDS) score ≥ 13, and four CCHL groups were analyzed using a logistic regression model and trend test. The proportions of pregnant women with a K6 score ≥ 10 and EPDS score ≥ 13 were 13.5 and 15.4%, respectively. In comparisons with the low CCHL group, the adjusted odds ratio (95% CI) for anxiety symptoms was 0.770 (0.604–0.982) in the high CCHL group, while those for depressive symptoms were 0.777 (0.639–0.946), 0.665 (0.537–0.824), and 0.666 (0.529–0.838) in the lower, higher, and high CCHL groups (all p < 0.05), respectively, after adjustments for potential confounding factors, such as age, weeks of gestation, complications, history, number of children, marital status, education, employment, and income. Higher CCHL was associated with significantly lower adjusted odds ratios for anxiety (p for trend = 0.019) and depressive symptoms (p for trend < 0.001). These results suggest a relationship between CCHL and ADs in pregnant women during the COVID-19 pandemic.
