Development and validation of the health literacy assessment tool for older people in Taiwan: Potential impacts of cultural differences

Development and validation of a nomogram for predicting anorexia of aging in older people

BACKGROUND

Anorexia of aging (AA) is a common geriatric syndrome that seriously endangers the health of older adults. Early identification of populations at risk of AAand the implementation of appropriate intervention measures hold significant public health importance. This study aimed to develop a nomogram for predicting the risk of AA among older people.

METHODS

We conducted a cross-sectional study involving 2144 community-dwelling older adults to evaluate the AA using the Simplified Nutritional Appetite Questionnaire. We utilized the Least Absolute Shrinkage and Selection Operator (LASSO) and logistic regression analysis to select variables and develop a nomogram prediction model. The predictive performance of the nomogram was evaluated using the Receiver Operating Characteristic (ROC) curves, calibration curves, Decision Curve Analysis (DCA), and internal validation.

RESULTS

The prevalence of AA among Chinese older adults was 21.7% (95%CI: 20.0%-23.5%). Age, sex, family economic level, smoking status, dysphagia, loneliness, depressive symptoms, living alone, health literacy, life satisfaction, and body mass index have been identified as predictive factors for AA among older people. The nomogram constructed based on these predictive factors showed an area under the curve (AUC) of 0.766 (95%CI: 0.742-0.791), indicating good calibration and discrimination ability. Additionally, the results obtained from the 10-fold cross-validation process confirmed the nomogram's good predictive capabilities. Furthermore, the DCA results showed that the nomogram has clinical utility.

CONCLUSION

The nomogram constructed in this study serves as an effective tool for predicting anorexia of aging among community-dwelling older adults. Its implementation can help community healthcare workers evaluate the risk of AA in this population and identify high-risk groups.

Health literacy and falls among community-dwelling older people in China: is there a sex difference?

BACKGROUND

Health literacy is one of the important determinants of healthy aging, yet few studies have focused on the association between health literacy and falls.

AIMS

This study aims to explore the relationship between health literacy and falls, with a focus on sex differences among older people in China.

METHODS

This cross-sectional study enrolled 2,144 older people aged ≥ 60 years from Shandong Province, China in 2021. We used general health literacy screening scale to assess health literacy, and collected the incidence of falls in the past year. Logistic regression models were employed to analyze the relationship between health literacy and falls. We investigated the sex differences by subgroup analyses.

RESULTS

The prevalence of adequate health literacy and falls was 21.7% (95% CI: 20.0-23.5%) and 25.4% (95% CI: 23.6-27.3%), respectively. In a fully-adjusted model, adequate health literacy was associated with a lower prevalence of falls in older adults (OR = 0.71, 95%CI: 0.52-0.96). Subgroup analysis revealed sex differences in this relationship (Pfor interaction <0.05). Specifically, the female group showed no significant relationship between health literacy and falls (OR = 0.92, 95% CI: 0.59-1.44); however, the male group demonstrated a robust and significant relationship (OR = 0.58, 95% CI: 0.37-0.90).

CONCLUSIONS

Older people with adequate health literacy have lower prevalence of falls, which appears to differ by sex. This relationship was significant among men but not among women. These findings emphasize the need for policymakers and healthcare providers to consider sex differences when designing and implementing programs aimed at improving health literacy and preventing falls in the older population. Improving health literacy among older women could be a strategic component in bridging sex inequality in falls.

Associations between digital literacy, health literacy, and digital health behaviors among rural residents: evidence from Zhejiang, China

OBJECTIVE

Within the digital society, the limited proficiency in digital health behaviors among rural residents has emerged as a significant factor intensifying health disparities between urban and rural areas. Addressing this issue, enhancing the digital literacy and health literacy of rural residents stands out as a crucial strategy. This study aims to investigate the relationship between digital literacy, health literacy, and the digital health behaviors of rural residents.

METHODS

Initially, we developed measurement instruments aimed at assessing the levels of digital literacy and health literacy among rural residents. Subsequently, leveraging micro survey data, we conducted assessments on the digital literacy and health literacy of 968 residents in five administrative villages in Zhejiang Province, China. Building upon this foundation, we employed Probit and Poisson models to empirically scrutinize the influence of digital literacy, health literacy, and their interaction on the manifestation of digital health behaviors within the rural population. This analysis was conducted from a dual perspective, evaluating the participation of digital health behaviors among rural residents and the diversity to which they participate in such behaviors.

RESULTS

Digital literacy exhibited a notably positive influence on both the participation and diversity of digital health behaviors among rural residents. While health literacy did not emerge as a predictor for the occurrence of digital health behavior, it exerted a substantial positive impact on the diversity of digital health behaviors in the rural population. There were significant interaction effects between digital literacy and health literacy concerning the participation and diversity of digital health behaviors among rural residents. These findings remained robust even after implementing the instrumental variable method to address endogeneity issues. Furthermore, the outcomes of robust analysis and heterogeneity analysis further fortify the steadfastness of the aforementioned conclusions.

CONCLUSION

The findings suggest that policymakers should implement targeted measures aimed at enhancing digital literacy and health literacy among rural residents. This approach is crucial for improving rural residents' access to digital health services, thereby mitigating urban-rural health inequality.

Prospective association of eHealth literacy and health literacy with physical activity among Chinese college students: a multiple mediation analysis

Background

The COVID-19 pandemic has decreased physical activity (PA) while increasing demand for electronic health resources. eHealth literacy (EHL) is expected to aid eHealth use and health promotion. EHL was raised on the grounds of health literacy (HL). This study explored the associations among EHL, HL, and PA in Chinese college students and identified mediating mechanisms in the EHL/HL-PA relationship.

Methods

An integrated social-cognitive model was proposed. A total of 947 Chinese college students (52.8% women, age = 19.87 ± 1.68 years) completed the three-wave data collection. Path analysis was performed.

Results

An adequate good-to-fit model was indicated. Perceived EHL (PEHL) was significantly associated with perceived HL (PHL) and HL performance (HLP); PHL was negatively related to HLP; PEHL was significantly associated with self-efficacy (SE) and social support (SS); PHL had a significant effect on SS but not SE; HLP significantly affected SS but not SE; SS and SE positively predicted intention (INT), which then predicted PA. SS mediated PEHL/PHL-INT links; SE mediated the PEHL-INT link; SS and INT jointly mediated PEHL/PHL/HLP-PA; SE and INT jointly mediated PEHL-PA.

Conclusion

Relationships among EHL, HL, and PA were explored with multiple mediating mechanisms identified. Differential SE and SS roles in EHL/HL-PA links suggest new mechanisms to inform EHL/HL intervention development.

Development and Validation of a Breastfeeding Health Literacy Scale (BFHLS) for Taiwanese Pregnant Women

BACKGROUND

Breastfeeding is the best source of nutrition for infants. Health literacy is a critical factor affecting breastfeeding rates.

RESEARCH AIMS

The aim of this research was to develop and test the Breastfeeding Health Literacy Scale to determine its validity and reliability.

METHODS

This study featured a cross-sectional telephone survey design. Researchers reviewed the literature and used expert opinions to develop the content-validated 30-item Breastfeeding Health Literacy Scale covering five dimensions. We examined internal consistency, exploratory factor analysis, and confirmatory factor analysis to assess reliability and construct validity. A Taiwanese government organization provided potential participants' contact information. After mailing an invitation letter, researchers phoned all participants to invite participation, obtain oral consent and complete a Breastfeeding Health Literacy Scale and collect demographic data.

RESULTS

Participants (N = 300) had a mean age of 31.8 (SD = 4.66) years. The item-level content validity index was 0.67 to 1.00 and scale-content validity index was 0.94. After performing exploratory factor analysis, three factors were extracted. Examining content factor analysis for the three factors resulted in χ2/df = 2.05; p < .001; goodness of fit index = 0.90; Comparative Fit Index (CFI) = 0.96; and Root Mean Square Error of Approximation (RMSEA) = 0.06. Cronbach's alphas on the total scale and the subscales ranged from 0.87 to 0.94. Women with multigravida, breastfeeding information from physicians and nurses, and previous breastfeeding experience had better breastfeeding health literacy.

CONCLUSIONS

Psychometric analysis demonstrated that the newly developed 20-item Breastfeeding Health Literacy Scale is a valid self-assessment instrument. Improving breastfeeding health literacy during pregnancy could help enable breastfeeding success.

Revised Chinese resident health literacy scale for the older adults in China: simplified version and initial validity testing

Objective

This study aimed to develop a short version of the Chinese Resident Health Literacy Scale focused on older adults in China, and further assess the reliability and validity of this short version.

Methods

The data was from a cross-sectional community-based older adults health survey conducted in 2020. The total of 5,829 older adults were randomly divided into two parts using for the simplification and assessment of the scale, respectively. Item Response Theory (IRT) and Differential Item Functioning (DIF) were used for item analysis and scale simplification. Cronbach's alpha and McDonald's omega were used to assess the reliability and three factors Confirmatory Factor Analysis (CFA) was used to assess the validity, which were compared to the original version. Moreover, Multi-group Confirmatory Factor Analysis (MCFA) was used to test the model invariance of the short version across groups of gender, age groups, level of education, and cognitive status.

Results

The simplified version consisted of 27 items taken from 50 original items, of them 11 items from the dimension of knowledge and attitudes, 9 items from the dimension of behavior and lifestyle, and 7 items from the dimension of health-related skills. The overall Cronbach's alpha and McDonald's omega were both 0.87 (95%CI: 0.86-0.88). The goodness-of-fits of CFA in simplified version were still acceptable in CFI, TLI, GFI, and RMSEA, even improved in CFI, TLI, and GFI compared to those of original version. Also, the model was stable and invariant in MCFA across gender, cognitive status, and educational level groups.

Conclusion

In this study, we formed a simplified instrument for measuring health literacy focused on older adults in China. This short version might be more suitable for the priority recommendation in extended tracking of the dynamic changes on the levels of health literacy in the whole life cycle in public health settings. Further research might be to identify the cut-off values to distinguish the older adults with different levels of health literacy.

Development and validation of the caregiver needs and resources assessment

Introduction

Existing caregiver assessment tools were long criticized for focusing on the needs and burden while neglecting the importance of the resources. The current study aimed to develop a multidimensional and time-effective assessment tool that measures both needs and resources of non-paid family caregivers of older adults for screening and service-matching purposes.

Methods

Items of the Caregiver Needs and Resources Assessment (CNRA) were developed from extensive literature reviews and focus group interviews of family caregivers and social workers in the field. In addition, we collected 317 valid responses from family caregivers of older adults from local non-government organizations in examining the psychometric properties of the CNRA.

Results

The results revealed a 12-factor structure that fitted nicely into the conceptual frame of needs and resources domains. Need factors were positively associated with mental health symptoms, while resource factors were positively associated with peace in mind, meaning-making, and personal gain measures. The 36-item CNRA revealed good internal reliability and convergent validity.

Discussion

The CNRA has the potential to be used as a compact yet balanced assessment tool for understanding both the needs and resources of caregivers for human service professionals.

Developing a Health Literacy Scale for adults in Hong Kong: A modified e-Delphi study with healthcare consumers and providers

INTRODUCTION

Health literacy (HL) refers to individuals' abilities to process and use health information to promote health. This study aimed to develop the first HL measurement tool for the Chinese Hong Kong population.

METHODS

A two-phase methodology was adopted. In Phase I, evidence synthesis with a deductive method was conducted to formulate the item list from the literature. In Phase II, a modified e-Delphi survey was conducted among stakeholders (i.e., healthcare providers and healthcare consumers) to confirm the content validity of the item list. The stakeholders were invited to rate the relevance of each draft item on a 4-point scale and provide suggestions for revisions, removal or adding new items.

RESULTS

In Phase I, a total of 34 items covering functional, interactive and critical HL were generated. In Phase II, to obtain a balanced view from experts and laypeople, healthcare professionals (n = 12) and consumers (n = 12) were invited to participate in the Delphi panel. The response rates of the three rounds were 100%. After the third round, the consensus was reached for 31 items, and no further comments for adding or revising items were received. All items exhibited excellent content validity (item content validity index: 0.79-1.00; K*: 0.74-1.00).

CONCLUSIONS

A Health Literacy Scale for Hong Kong was developed. Compared with existing HL scales, the scale fully operationalized the skills involved in functional, interactive and critical HL. The Delphi study shows evidence supporting the high content validity of all items in the scale. In future studies, these items should undergo rigorous testing to examine their psychometric properties in our target population groups. By illuminating the details in the development process, this paper provides a deeper understanding of the scale's scope and limitations for others who are interested in using this tool.

PATIENT OR PUBLIC CONTRIBUTION

Public as healthcare consumers, in addition to healthcare providers, were involved in developing a new HL scale for this study. The input from the public contributed to examining the scale's content validity by judging whether all items reflected the skills that they need to find and use health-related information in their daily life.

Development and validation of a comprehensive health literacy tool for adults in Hong Kong

Introduction

Health literacy (HL) refers to an individual's ability to process and use health information to make health-related decisions. However, previous HL scales did not fully cover all aspects of this concept. This study aimed to develop a comprehensive Hong Kong HL scale (HLS-HK) and evaluate its psychometric properties among Chinese adults.

Methods

A scale of 31-item covering Nutbeam's framework, namely functional and interactive HL (FHL and IHL), and critical HL (CHL) within three subdomains: critical appraisal of information, understanding of social determinants of health, and actions to address social determinants of health, was developed based on previous literature review and Delphi survey. Cognitive interviews were performed to examine all items' face validity in terms of three aspects: comprehensiveness, clarity, and acceptability. A cross-sectional survey was conducted to investigate the scale's psychometric properties, including its internal consistency reliability, factorial structure validity, convergent validity, and predictive validity.

Results

Nine interviewees participated in the cognitive interviews in October 2021. Based on the input from respondents, two items were deleted, two items were combined, and several items' wording was revised. The other items were clear and readable. Finally, 28 items remained. A total of 433 adults completed the questionnaire survey between December 2021 and February 2022. After excluding one item with low inter-item correlations, the scale's internal consistency reliability was acceptable, with a Cronbach's alpha of 0.89. Exploratory factor analysis produced a five-factor model, as shown in the original theoretical framework. These factors accounted for 53% of the total variance. Confirmatory factor analysis confirmed that the fit indices for this model were acceptable (comparative fit index = 0.91, root mean square error of approximation = 0.06, and root mean square residual = 0.06). The scale is also significantly correlated with theoretically selected variables, including education and self-rated health.

Conclusion

The HLS-HK is a valid and reliable tool for evaluating HL. Compared with existing tools, this scale extended the operationalization of FHL, IHL, and CHL and fully operationalized the CHL via three subdomains. It can be used to understand the difficulties and barriers that people may encounter when they use health-related information and services.

Associations between health literacy, digital skill, and eHealth literacy among older Chinese adults: A cross-sectional study

Objective

Digital divide in health-related technology use is a prominent issue for older adults. Improving eHealth literacy may be an important solution to this problem. This study aimed to explore the associations between health literacy, digital skills, and eHealth literacy among older Chinese adults.

Methods

A total of 2,144 older adults (mean age, 72.01  ±  6.96 years) from Jinan City, China participated in this study. The eHealth Literacy Scale was used to measure eHealth literacy in older adults. A linear regression model was used to analyze the associations among health literacy, digital skills, and eHealth literacy in older Chinese adults.

Results

The mean eHealth literacy score of the older adults was 17.56  ±  9.61. After adjusting for sociodemographic characteristics and experience of Internet usage, the results of the linear regression showed that health literacy (B  =  0.258, 95% confidence interval (CI)  =  0.215-0.302, P< 0.001) and digital skills (B  =  0.654, 95% CI  =  0.587-0.720, P < 0.001) were positively associated with eHealth literacy. Sensitivity analyses revealed that this association remained robust.

Conclusions

The level of eHealth literacy in older Chinese adults is low. Health literacy and digital skills are associated with eHealth literacy in older adults. In the future, eHealth literacy intervention research should be considered from the perspective of health literacy and digital skills.

Validity and Reliability of the Parental Health Literacy Questionnaire for Caregivers of Children Aged 0 to 3 Years in China

Caregivers' health literacy plays a vital role in the quality of parenting and significantly impacts children's physical and psychological health. However, the instruments to assess the health literacy of caregivers of children aged 0 to 3 years are lacking. This study aimed to evaluate the reliability and validity of the Chinese Parental Health Literacy Questionnaire (CPHLQ) in China. We conducted a cross-sectional study. Six hundred and thirty-four caregivers of children aged 0 to 3 years were recruited from Shandong, Yunnan, and Shaanxi Provinces, representing the eastern, central, and western regions of China, between November 2020 and January 2021. The reliability was evaluated by internal consistency reliability and split-half reliability. The construct validity was determined by confirmatory factor analysis. Social determinants of parental health literacy were assessed by multivariate linear regression model. Results showed that CPHLQ had satisfactory reliability and acceptable construct validity. Mothers compared to other types of caregivers, higher education levels, and nuclear or extended families compared to other family compositions were significantly associated with higher parental health literacy. The study further demonstrated that CPHLQ is a reliable and valid instrument to measure the health literacy of caregivers of children aged 0 to 3 years in the Chinese population. It can be used as an evaluation tool for intervention research, to inform policy-making and future health education interventions of improving caregivers' health literacy.

Measuring health literacy: A systematic review and bibliometric analysis of instruments from 1993 to 2021

BACKGROUND

It has been about 30 years since the first health literacy instrument was developed. This study aimed to review all existing instruments to summarize the current knowledge on the development of existing measurement instruments and their possible translation and validation in other languages different from the original languages.

METHODS

The review was conducted using PubMed, Web of Science, Scopus, and Google Scholar on all published papers on health literacy instrument development and psychometric properties in English biomedical journals from 1993 to the end of 2021.

RESULTS

The findings were summarized and synthesized on several headings, including general instruments, condition specific health literacy instruments (disease & content), population- specific instruments, and electronic health. Overall, 4848 citations were retrieved. After removing duplicates (n = 2336) and non-related papers (n = 2175), 361 studies (162 papers introducing an instrument and 199 papers reporting translation and psychometric properties of an original instrument) were selected for the final review. The original instruments included 39 general health literacy instruments, 90 condition specific (disease or content) health literacy instruments, 22 population- specific instruments, and 11 electronic health literacy instruments. Almost all papers reported reliability and validity, and the findings indicated that most existing health literacy instruments benefit from some relatively good psychometric properties.

CONCLUSION

This review highlighted that there were more than enough instruments for measuring health literacy. In addition, we found that a number of instruments did not report psychometric properties sufficiently. However, evidence suggest that well developed instruments and those reported adequate measures of validation could be helpful if appropriately selected based on objectives of a given study. Perhaps an authorized institution such as World Health Organization should take responsibility and provide a clear guideline for measuring health literacy as appropriate.

Association of functional, interactive, and critical health literacy with good self-rated health among Taiwanese community-dwelling older adults

The functional, interactive, and critical domains of health literacy are associated with health. However, studies examining the relationship between health literacy subdomains and health in the Chinese-speaking context are still limited. Thus, we aimed to examine the association of functional, interactive, and critical health literacy with self-rated health among older Taiwanese adults. A total of 1,072 participants aged 60 or older were included in the analysis. Health literacy was measured by the 11-item short-form Mandarin Health Literacy Scale and validated tools. Self-rated health was categorized into good (good/very good), fair, and poor (poor/very poor) status. Multinomial logistic regression revealed that only interactive health literacy was associated with reporting good health status (OR = 2.30; 95% CI = 1.65 to 3.21). Conversely, all health literacy subdomains were not associated with reporting poor health. This study suggested that interactive health literacy was the key determinant of good self-rated health status for community-dwelling older adults.

Simple scoring algorithm to identify community-dwelling older adults with limited health literacy: a cross-sectional study in Taiwan

OBJECTIVE

Health literacy (HL) is the degree of individuals' capacity to access, understand, appraise and apply health information and services required to make appropriate health decisions. This study aimed to establish a predictive algorithm for identifying community-dwelling older adults with a high risk of limited HL.

DESIGN

A cross-sectional study.

SETTING

Four communities in northern, central and southern Taiwan.

PARTICIPANTS

A total of 648 older adults were included. Moreover, 85% of the core data set was used to generate the prediction model for the scoring algorithm, and 15% was used to test the fitness of the model.

PRIMARY AND SECONDARY OUTCOME MEASURES

Pearson's χ² test and multiple logistic regression were used to identify the significant factors associated with the HL level. An optimal cut-off point for the scoring algorithm was identified on the basis of the maximum sensitivity and specificity.

RESULTS

A total of 350 (54.6%) patients were classified as having limited HL. We identified 24 variables that could significantly differentiate between sufficient and limited HL. Eight factors that could significantly predict limited HL were identified as follows: a socioenvironmental determinant (ie, dominant spoken dialect), a health service use factor (ie, having family doctors), a health cost factor (ie, self-paid vaccination), a heath behaviour factor (ie, searching online health information), two health outcomes (ie, difficulty in performing activities of daily living and requiring assistance while visiting doctors), a participation factor (ie, attending health classes) and an empowerment factor (ie, self-management during illness). The scoring algorithm yielded an area under the curve of 0.71, and an optimal cut-off value of 5 represented moderate sensitivity (62.0%) and satisfactory specificity (76.2%).

CONCLUSION

This simple scoring algorithm can efficiently and effectively identify community-dwelling older adults with a high risk of limited HL.

[Health literacy in low- and middle-income countries: a systematic review]

Health literacy (HL) is linked to individual capacities of access, understanding, assessment and application of health information to make decisions in everyday life, in order to maintain or improve health. The scope of this article is to review studies on HL conducted in low- and middle-income countries, with an emphasis on the definition used for HL. It involved a systematic search in the Medline, Embase, Scopus, LILACS and SciELO databases. It included studies that showed the definition of HL, studies in countries with low- and middle-income economies and Latin American studies. Initially, a selection of studies was made by reading the titles and/or abstracts. Two independent evaluators conducted the reading of the full text. Disagreements were discussed by consensus. A total of 6,025 references were located and 36 were selected for the final sample. Most studies (58.3%) were from countries on the Asian continent, followed by studies from South American countries (27.8%), including Brazil. Most studies (58.3%) evaluated the functional dimension of the HL (FHL). The most frequent definitions were from the Institute of Medicine and from the World Health Organization. Approximately 30% of the studies that evaluated FHL used broader definitions of HL as theoretical frameworks.

A new comprehensive oral health literacy scale: development and psychometric evaluation

BACKGROUND

It has been widely accepted that oral health status is related to oral health literacy. The need to measure oral health literacy has led to the development of measurement instruments. This study aimed to develop a comprehensive instrument for adults and to examine its reliability and validity in China.

METHODS

A three-step design process was used. First, a literature review and expert panel discussion were used to draw up a 37-item pool covering oral health knowledge, belief, practice, skill, and functional oral health literacy. The Delphi method was used to delete and modify questions in the item pool. The draft instrument was evaluated by nine experts and the consensus among them was calculated using the content validity index. The scale was then used to conduct a psychometric study among 370 participants from community health centers in Beijing. Construct validity, discriminant validity and concurrent validity were examined. The Cronbach's alpha coefficient, and test-retest methods were used to assess reliability.

RESULTS

The final scale included 30 items across four dimensions. The item-level content validity index was 0.90. Exploratory factor analysis extracted four fixed factors, and the result of the Kaiser-Meyer-Olkin and Bartlett's tests was 0.752, with the model explaining 35.21% of the total variance. The four dimensions were associated with oral health knowledge, perceptions of oral health issues, oral health practice and skills, and functional oral health literacy. The mean score of the lowest 27% was significantly lower than the highest 27% (P < 0.01), suggesting adequate discriminant validity. The associations between comprehensive oral health literacy scores and educational level, income and self-reported literacy level were significant (P < 0.001), showing adequate overall concurrent validity. Internal consistency and test-retest reliability were acceptable, with a Cronbach's alpha of 0.72 and a total test-retest reliability coefficient of 0.979.

CONCLUSIONS

Initial testing of the comprehensive oral health literacy instrument suggested that it is a valid and reliable instrument to evaluate individuals' oral health literacy, with four dimensions for evaluating knowledge, belief, skills, and functional oral health literacy.

Generic Health Literacy Measurements for Adults: A Scoping Review

BACKGROUND

Generic health literacy measurement (GHLM) is an important tool to identify individuals with limited health literacy and can assist the design of tailored interventions for improving public health literacy. However, there is no consensus on measuring generic health literacy. The present study aims to review current GHLM used for adults in the literature.

METHODS

A scoping review was undertaken to map the available measurements designed to assess generic health literacy.

RESULTS

The review identified 19 GHLM for adults. Most of them applied a multidimensional definition of health literacy with a focus on individuals' abilities to access, appraise, understand, and apply health information and services. Nutbeam's conceptual model and Sørensen's integrated model were widely used among the identified measures as the theoretical foundation. While the social determinants of health (SDH) were acknowledged in the two models, it remains unmentioned in many of the identified measures based on the Nutbeam's model and needs further development in the measure based on the Sørensen's model. A total of 39 different domains were assessed in the 19 measurements: prose was identified in 8 measurements and was the most prominent domain; followed by numeracy (n = 7) and interactive (n = 7). SDH related domains such as social support (n = 3), social capital (n = 1) were seldom included in the identified measurements.

CONCLUSIONS

Although current GHLM adopted a multidimensional construct, they mainly focused on individuals' abilities and SDH has not been well-developed in the assessment. Further research is required to advance the measuring of the interaction between SDH and health literacy.

Exploring the Influencing Factors of Health Literacy among Older Adults: A Cross-Sectional Survey

Background and Objectives: To investigate the health literacy (HL) among older adults in Taiwan, we referenced an existing integrated model of HL to confirm the influencing factors of HL in older adults. We propose this study to examine the personal, situational, and socioenvironmental factors influencing HL among older adults. Materials and Methods: A cross-sectional survey was conducted at a district hospital and affiliated community center in northern Taiwan from August 2016 to May 2017. This study used the Mandarin Chinese version of the European Health Literacy Survey Questionnaire (EU-Q47). We designed three models based on the three domains of HL. Model 1 assesses personal factors. Model 2 incorporates situational factors. Model 3 adds the socioenvironmental factor. Results: We recruited 161 participants aged over 65 years. Most adults in this study had limited overall HL. The final regression model revealed that age >85 years, unknown insurance status, and dominant spoken dialect of Hakka or Taiwanese were significantly associated with higher scores of HL. Conclusions: Our study results may help clinicians with early identification of older adults at high risk for poor HL and help health administrators establish geriatric policies and health education plans.

Tools to measure health literacy among Chinese speakers: A systematic review

OBJECTIVE

Health literacy measurement can identify healthcare consumers' needs and help inform healthcare service delivery. The objective of this review is to identify and evaluate tools to measure health literacy among Chinese speakers.

METHODS

A systematic literature search was undertaken in nine databases, both English and Chinese, on articles published from the databases' inception to May 2018, addressing health literacy among Chinese speakers.

RESULTS

Ten health literacy instruments in the Chinese language were reported in 17 studies, of which ten were published in English and seven in Chinese. Of the 17 studies, six reported on a new instrument, while the remainder reported on derivative instruments. All, except for one, are self-administered. These studies applied various implicit or explicit conceptual or operational health literacy definitions. The psychometric strength varied across the instruments.

CONCLUSIONS

A number of instruments are available for assessing health literacy among Chinese speakers. Careful selection is recommended, given the variation in components and psychometric properties assessed.

PRACTICE IMPLICATIONS

This review can be used by healthcare providers and researchers to select effective health literacy tools to examine patients' ability to understand and apply health information so that services can be more appropriately tailored to Chinese speaking patients.

Mid-arm muscle circumference as an indicator of osteoporosis in community-dwelling older men

BACKGROUND

Osteoporosis is an underdiagnosed disease and is lack of convenient and cost-efficient screening tool. We undertook a study to determine whether mid-arm muscle circumference (MAMC) was associated with osteoporosis.

DESIGN

Data were retrieved from the National Health and Nutrition Examination Survey (NHANES) III participants (aged 40-90 years). We divided the MAMC into tertile groups (T1, T2, and T3). Femoral neck bone density was analyzed because it was the reference skeletal site for defining osteoporosis in epidemiological studies. Participants with T- scores ≤ -2.5 were categorized as having osteoporosis. Multivariate logistic regression models were used to evaluate the associations between the MAMC tertiles and osteoporosis.

RESULTS

After adjustment for multiple covariates, osteoporosis was significantly inversely associated with the MAMC tertiles in the male group (T2/T1: OR 0.47, 95 % CI 0.30-0.75 and T3/T1: OR 0.34, 95 % CI 0.18-0.64), whereas nonsignificant association was found in the female group (T2/T1: OR 0.92, 95 % CI 0.70-1.20 and T3/T1: OR 0.84, 95 % CI 0.47-1.53). Subgroup analyses (40-64 and ≥65 years old; BMI <25 and ≥25 kg/m²) revealed consistent results.

CONCLUSION

The MAMC is an economical and practical tool that may assist in screening and early diagnosis of osteoporosis for the older men.
