Effects on Engagement and Health Literacy Outcomes of Web-Based Materials Promoting Physical Activity in People With Diabetes: An International Randomized Trial

The mediating effect of traditional Chinese medicine (TCM) health literacy between TCM culture promotion and residents' health status

Background

Traditional Chinese medicine (TCM) is a medical system with a long history and unique theories and techniques, playing a crucial role in maintaining and promoting human health. Disseminating TCM cultural knowledge is essential for enhancing the TCM health literacy and health status of people. This study aimed to investigate how TCM health literacy mediated the relationship between the TCM cultural ambiance and people's health status.

Methods

A multi-stage random sampling method was employed to select 22,125 permanent residents in Jiangsu Province for a survey aimed at examining the popularization of TCM culture. The survey categorized the intensity of TCM cultural ambiance into four grades (0-3) based on the promotion activities in various settings, including street/community, medical service institutions, and educational/work institutions. Furthermore, the survey evaluated TCM health literacy, overall health status, and prevalence of chronic diseases using the 2017 Chinese Citizens TCM Health Literacy Survey Questionnaire. The regression analysis was used to examine the correlation between the TCM cultural ambiance and TCM health literacy and health status. Also, a mediation model was applied to explore the mediating effect of TCM health literacy on the TCM cultural ambiance and the public's self-assessment of health and reporting of chronic diseases.

Results

The rate of popularization of TCM culture was 79.3% in Jiangsu Province, with a TCM health literacy level of 14.76%. The average score for public self-assessment of health was 37.80 ± 9.70, and the prevalence of chronic diseases was reported at 32.66%. A positive correlation was observed between cultural promotion ambiance and TCM health literacy. The impact of the cultural promotion ambiance on health literacy also increased with the increase in promotion grade (P < 0.001). The correlation analysis showed no statistically significant correlation of promotion grade 1 [β = 0.21, 95% confidence interval (CI): -0.26 to 0.67] with the health status of residents, whereas promotion grades 2 (β = 1.47, 95% CI: 1.12-1.83) and 3 (β = 4.61, 95% CI: 4.19-5.04) were positively correlated with self-health evaluation. TCM health literacy was positively correlated with self-health evaluation (β = 2.10, 95% CI: 1.72-2.48) and negatively correlated with the risk of chronic diseases (odds ratio = 0.53, 95% CI: 0.48-0.58). The analysis of the mediating effect revealed that the TCM cultural ambiance directly impacted self-health evaluation and the prevalence of chronic diseases, with coefficients of 1.131 and -0.027 (P < 0.001), respectively. TCM health literacy had a significant mediating effect on the relationship between the cultural promotion ambiance and self-health evaluation, as well as with the prevalence of chronic diseases (P < 0.001). The mediating effect accounted for 17.8% and 42.2% of the total effect, respectively.

Conclusions

TCM health literacy served as a mediating factor in the positive relationship between the TCM cultural ambiance and health status. Theoretically, it can improve the overall health of residents by intensifying the dissemination of TCM culture and enhancing their health literacy.

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.

Patient enablement and health-related quality of life for patients with chronic back and knee pain: a cross-sectional study in primary care

BACKGROUND

Chronic back and knee pain impairs health- related quality of life (HRQoL) and patient enablement can improve HRQoL.

AIM

To determine whether enablement was a moderator of the effect of chronic back and knee pain on HRQoL.

DESIGN AND SETTING

A cross-sectional study of Chinese patients with chronic back and knee problems in public primary care clinics in Hong Kong.

METHOD

Each participant completed the Chinese Patient Enablement Instrument-2 (PEI-2), the Chinese Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Pain Rating Scale (PRS). Multivariable regression examined the effects of PRS score and PEI-2 score on WOMAC total score. A moderation regression model and simple slope analysis were used to evaluate whether the interaction between enablement (PEI-2) and pain (PRS) had a significant effect on HRQoL (WOMAC).

RESULTS

Valid patient-reported outcome data from 1306 participants were analysed. PRS score was associated with WOMAC total score (β = 0.326, P<0.001), whereas PEI-2 score was associated inversely with WOMAC total score (β = -0.260, P<0.001) and PRS score. The effect of the interaction between PRS and PEI-2 (PRS × PEI-2) scores on WOMAC total score was significant (β = -0.191, P<0.001) suggesting PEI-2 was a moderator. Simple slope analyses showed that the relationship between PRS and WOMAC was stronger for participants with a low level of PEI-2 (gradient 3.056) than for those with a high level of PEI-2 (gradient 1.746).

CONCLUSION

Patient enablement moderated the impact of pain on HRQoL. A higher level of enablement can lessen impairment in HRQoL associated with chronic back and knee pain.

Effects of Using Websites on Physical Activity and Diet Quality for Adults Living With Chronic Health Conditions: Systematic Review and Meta-Analysis

BACKGROUND

Adults with chronic health conditions need support to manage modifiable risk factors such as physical inactivity and poor diet. Disease-specific websites with health information on physical activity and diet quality may be effective in supporting adults in managing their chronic illnesses.

OBJECTIVE

The primary aim of this review was to determine whether using websites with health information can lead to improvements in physical activity levels or diet quality in adults with chronic health conditions.

METHODS

Randomized controlled trials evaluating the effectiveness of website use on levels of physical activity or diet quality in adults with chronic health conditions were included. MEDLINE, Embase, CINAHL, and the Physiotherapy Evidence Database were searched from the earliest available record until February 2023. Data for outcomes measuring physical activity levels; diet quality; and, where reported, self-efficacy and quality of life were independently extracted by 2 reviewers. The risk of bias was assessed using the Physiotherapy Evidence Database scale, and the overall certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. Where values were presented as the same unit of measure, postintervention scores were pooled for meta-analysis to yield an overall mean difference (MD). A standardized MD (SMD) was calculated for the pooled data in which different units for the same outcome were used. Individual trial data were described in cases where the data of trials could not be pooled.

RESULTS

A total of 29 trials (N=6418 participants) across 8 different disease groups with intervention periods ranging from 4 weeks to 12 months were included in the analysis. There was moderate-certainty evidence that using websites with health information increased levels of moderate to vigorous physical activity (MD=39 min/wk, 95% CI 18.60-58.47), quality of life (SMD=0.36, 95% CI 0.12-0.59), and self-efficacy (SMD=0.26, 95% CI 0.05-0.48) and high-certainty evidence for reduction in processed meat consumption (MD=1.1 portions/wk, 95% CI 0.70-1.58) when compared with usual care. No differences were detected in other measures of diet quality. There was no increased benefit for website users who were offered additional support.

CONCLUSIONS

The use of websites for risk factor management has the potential to improve physical activity levels, quality of life, and self-efficacy as well as reduce processed meat consumption for adults living with chronic health conditions when compared with usual care. However, it remains unclear whether using websites leads to meaningful and long-lasting behavior change.

"A bit of everything": Health literacy interventions in chronic conditions - a systematic review

OBJECTIVE

To systematically evaluate health literacy (HL) interventions in chronic conditions by exploring theoretical perspectives, intervention content and effectiveness.

METHOD

We searched MEDLINE, Cochrane, CINAHL, EMBASE, ERIC, Web of Science and PsycINFO. Standardised systematic review methods were used, and sequences informing our research question were extracted and analysed. The study includes a descriptive summary of the included papers.

RESULTS

We included 39 unique interventions, with diabetes and heart disease as the most targeted chronic conditions. Fifty-four percent of papers included a definition of HL, but the studies showed significant heterogeneity of theoretical underpinnings, modes, measures and content. We identified 23 HL measures, mostly assessing functional HL. The HL interventions were often more complex than the measures indicated. A significant change in HL was found in 28 studies. Study quality was generally poor.

CONCLUSIONS

Interventions optimizing HL appear important to improve health outcomes in chronic conditions. To ensure cumulative knowledge development of this field we need theory-based interventions, consistency in methods and more tailored and comprehensive measures to capture the interventions' complexity.

PRACTICE IMPLICATIONS

A more valid understanding of HL interventions and measurements is needed to reach an agreed understanding of their components and intentions.

A process evaluation, with mediation analysis, of a web-based intervention to augment primary care exercise referral schemes: the e-coachER randomised controlled trial

Background

The e-coachER trial aimed to determine whether adding web-based behavioural support to exercise referral schemes (ERS) increased long-term device-measured physical activity (PA) for patients with chronic conditions, compared to ERS alone, within a randomised controlled trial. This study explores the mechanisms of action of the e-coachER intervention using measures of the behaviour change processes integral to the intervention’s logic model.

Methods

Four hundred fifty adults with obesity, diabetes, hypertension, osteoarthritis or history of depression referred to an ERS were recruited in Plymouth, Birmingham and Glasgow. The e-coachER intervention comprising 7-Steps to Health was aligned with Self-Determination Theory and mapped against evidence-based behaviour change techniques (BCTs). Participants completed questionnaires at 0, 4, and 12 months to assess PA and self-reported offline engagement with core BCTs in day-to-day life (including action planning and self-monitoring) and beliefs relating to PA (including perceived importance, confidence, competence, autonomy and support). We compared groups at 4 and 12 months, controlling for baseline measures and other covariates. Mediation analysis using the product of coefficients method was used to determine if changes in process variables mediated intervention effects on moderate to vigorous physical activity (MVPA) recorded by accelerometer and self-report at 4- and 12-months.

Results

The internal reliability (Cronbach’s alpha) for all multi-item scales was > 0.77. At 4-months, those randomised to e-coachER reported higher levels of PA beliefs relating to importance (1.01, 95% confidence interval (CI): 0.42 to 1.61, p = 0.001), confidence (1.28, 95% CI: 0.57 to 1.98, p < 0.001), competence (1.61, 95% CI: .68 to 2.54, p = 0.001), availability of support (0.77, 95% CI: 0.07 to 1.48, p = 0.031), use of action planning (1.54, 95% CI: 0.23 to 2.85, p = 0.021) and use of self-monitoring (0.76, 95% CI: 0.19 to 1.32, p = 0.009) compared to ERS alone. There were no intervention effects on autonomous beliefs or perceived frequency of support, compared to ERS alone. At the 12-month follow-up, participants belief in the importance of PA was the only process measure to remain significantly higher in the e-coachER group when compared to ERS alone (0.75, 95% CI: 0.05 to 1.45). Intervention effects on perceived importance (2.52, 95% CI: 0.45 to 5.39), action planning (1.56, 95% CI: 0.10 to 3.54) and self-monitoring (1.92, 95% CI: 0.21 to 4.33) at 4-months significantly mediated change in accelerometer measured MVPA at 12-months (recorded in ≥ 10-min bouts).

Conclusions

e-coachER led to some short-term changes in most process outcomes. Some of these processes also appeared to mediate e-coachER effects on changes in accelerometer measured MVPA. Further work should be carried out to understand how best to design and implement theoretically underpinned web-based physical activity promotion interventions within ERS.

Association between health literacy and purpose in life and life satisfaction among health management specialists: a cross-sectional study

Purpose in life is anchored as a goal in national health promotion plans in several countries. Health literacy is the ability to find, understand, use, and evaluate health-related information; this ability has been investigated in terms of its effect on health outcomes and is said to play a critical role in health promotion. In the context of national health promotion, the effect of health literacy on purpose in life and life satisfaction remains unclear; therefore, this study aims to determine the effect of health literacy. A cross-sectional study was conducted on Japanese health management specialists (N = 1920). Health literacy was measured using the Communicative and Critical Health Literacy scale. Purpose in life and life satisfaction were measured using the Ikigai-9 scale and a Likert scale, respectively. We analyzed the associations between health literacy and purpose in life and life satisfaction with regression analyses. Age, sex, income, education, marital status, psychological stress, and diseases as present illness were adjusted in the statistical models. Our multiple linear regressions indicated that health literacy was significantly associated with purpose in life (β = 0.199, p < 0.001), after adjusting for covariates (age, sex, income, education, marital status, psychological factor, and disease status). Life satisfaction was also significantly associated with health literacy (β = 0.126, p < 0.001). Health literacy is associated with purpose in life and life satisfaction among specialists in health management. Health literacy plays a critical role in lifestyle-related disease prevention and health promotion. Interventions to improve health literacy may be warranted in the context of national health promotion.

Developing public transport messaging to provide crowding information during COVID-19: Application of the COM-B model and behaviour change wheel

The COVID-19 outbreak meant that using public transport was potentially unsafe for risk of catching and transmitting the virus. UK anxiety is high with lockdowns preventing a normal way of life for over a year. A lack of ability to travel freely causes numerous declines in quality of life including social isolation and poor physical and mental health. People need crowding information to choose safer travel options and subdue coronavirus. To provide effective guidance, it is essential to empirically formulate messaging to create clarity and trust which can be acted upon in confidence. Behaviour Change Techniques incorporating the Behaviour Change Wheel and COM-B model have been utilised in vast areas of public health intervention development and messaging. There is consensus that public transport information needs to be clearer and more accessible but BCTs have not been utilised in the development of public transport advice. This paper outlines the development of crowding messaging for public transport on a platform available to UK travellers. Barriers and facilitators were explored; related behaviours, intervention functions and behaviour change techniques were mapped. Specific message phrasing was developed utilising the mapped functions and advice from the literature. With the COVID-19 outbreak, having accessible and effective messaging for safely using public transport is a continuation of the work recently conducted examining the best ways to present public health information. It is important to be transparent when developing messaging and interventions accessible to the public and this work forms a basis for continued exploration and development in this area.

Adapting Behavioral Interventions for a Changing Public Health Context: A Worked Example of Implementing a Digital Intervention During a Global Pandemic Using Rapid Optimisation Methods

Background: A rigorous approach is needed to inform rapid adaptation and optimisation of behavioral interventions in evolving public health contexts, such as the Covid-19 pandemic. This helps ensure that interventions are relevant, persuasive, and feasible while remaining evidence-based. This paper provides a set of iterative methods to rapidly adapt and optimize an intervention during implementation. These methods are demonstrated through the example of optimizing an effective online handwashing intervention called Germ Defense. Methods: Three revised versions of the intervention were rapidly optimized and launched within short timeframes of 1-2 months. Optimisations were informed by: regular stakeholder engagement; emerging scientific evidence, and changing government guidance; rapid qualitative research (telephone think-aloud interviews and open-text surveys), and analyses of usage data. All feedback was rapidly collated, using the Table of Changes method from the Person-Based Approach to prioritize potential optimisations in terms of their likely impact on behavior change. Written feedback from stakeholders on each new iteration of the intervention also informed specific optimisations of the content. Results: Working closely with clinical stakeholders ensured that the intervention was clinically accurate, for example, confirming that information about transmission and exposure was consistent with evidence. Patient and Public Involvement (PPI) contributors identified important clarifications to intervention content, such as whether Covid-19 can be transmitted via air as well as surfaces, and ensured that information about difficult behaviors (such as self-isolation) was supportive and feasible. Iterative updates were made in line with emerging evidence, including changes to the information about face-coverings and opening windows. Qualitative research provided insights into barriers to engaging with the intervention and target behaviors, with open-text surveys providing a useful supplement to detailed think-aloud interviews. Usage data helped identify common points of disengagement, which guided decisions about optimisations. The Table of Changes was modified to facilitate rapid collation and prioritization of multiple sources of feedback to inform optimisations. Engagement with PPI informed the optimisation process. Conclusions: Rapid optimisation methods of this kind may in future be used to help improve the speed and efficiency of adaptation, optimization, and implementation of interventions, in line with calls for more rapid, pragmatic health research methods.

Translation, cross-cultural adaptation, and psychometric properties of the Brazilian Portuguese version of the DiAbeTes Education Questionnaire (DATE-Q)

BACKGROUND

The DiAbeTes Education Questionnaire (DATE-Q) is a self-administered tool developed to evaluate disease-related knowledge and to assess knowledge of five core components of rehabilitation programs: physical exercise, diet, psychosocial well-being, disease self-management, and complications.

OBJECTIVE

To translate and cross-culturally adapt into Brazilian Portuguese, and to test the psychometric properties of the DATE-Q for its use in Brazil.

METHODS

The process of translation and cross-cultural adaptation consisted of five steps: translation into Brazilian Portuguese, synthesis of translation, back translation, expert committee, and pilot test of pre-final version. The pre-final version was applied to a sample of 30 patients with diabetes. Psychometric properties (internal consistency, reliability, construct validity, and ceiling and floor effects) of the final version of the Brazilian Portuguese version of the DATE-Q were tested in a sample of 200 adults with diabetes.

RESULTS

There was no conceptual divergence between the original and the translated versions. Ten (50%) items of the DATE-Q were culturally adapted. Internal consistency (Cronbach's alpha coefficient = 0.6), reliability (intraclass correlation coefficient = 0.5), and construct validity (correlation between Diabetes Knowledge Scales and DATE-Q total scores: ρ = 0.7; P < 0.001) were confirmed. Ceiling or floor effects were not identified. The highest scoring item was about healthy eating. The average time for completion of the DATE-Q was 5 min and 51 s, and the completion rate was 100% for all items.

CONCLUSION

The Brazilian Portuguese version of the DATE-Q showed adequate psychometric properties, and results suggested that the tool can be used to assess disease-related knowledge in adults with diabetes in Brazil.

Assessing telehealth interventions for physical activity and sedentary behavior self-management in adults with type 2 diabetes mellitus: An integrative review

Type 2 diabetes is a chronic disease, requiring lifestyle management to prevent chronic complications. Increasing physical activity and reducing sedentary behavior are integral to maintaining glycemic control. The purpose of this study was to (1) appraise and synthesize the literature about physical activity and sedentary behavior intervention delivery via telehealth strategies in adults with type 2 diabetes mellitus and (2) to evaluate what is known about the effectiveness of such interventions on physical activity, sedentary behavior, and glycemic control. An integrative literature review was carried out, including the electronic databases PubMed, CINAHL, and PsychInfo, searching for articles published within the past 10 years, meeting specified inclusion and exclusion criteria, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement guidelines. Seventeen studies were included. Significant improvements in physical activity and sedentary behavior were identified in web and mobile phone-based interventions. Modest improvements in glycemic control were reported. Theoretical framework use and integration was limited, and intervention length and follow-up varied greatly in the studies reviewed. Outcomes were measured using both self-report and objective measures, but objective measures were used less frequently. Further, few studies have been conducted in the United States or in rural populations. Web and mobile phone-based telehealth interventions to increase physical activity, reduce sedentary behaviors, and improve glycemic control have been supported by the literature. A need exists for future studies that are theory-driven, include dose-specific measures, self-report and objective measures, and long-term follow-up. Examining intervention effects in rural populations is needed.

Supporting patients to be involved in decisions about their health and care: Development of a best practice health literacy App for Australian adults living with Chronic Kidney Disease

ISSUE ADDRESSED

Inadequate health literacy is common in those with chronic kidney disease (CKD), especially among culturally and linguistically diverse groups. Patient information for people with CKD, including those with kidney failure requiring dialysis, is often written beyond their literacy level, and many CKD-related apps are not accurate or evidence based. These represent important barriers to health care decision-making and equity in access to health care.

METHODS

We developed a cross-platform application (the "SUCCESS app") to support Australian adults with kidney failure requiring dialysis to actively participate in self-management and decision-making. App content was informed by health literacy theory which recognises the importance of reducing the complexity of health information as well as equipping consumers with the skills necessary to access, understand and act on this information. The development team comprised members of diverse backgrounds and expertise, including nursing, allied health, psychology, epidemiology, nephrology and IT, as well as consumer representatives.

RESULTS

Content areas included diet, fluids, medicine, physical activity, emotional well-being and supportive care, chosen as they represent important decision points in the CKD trajectory. To support functional health literacy, a four-step process to simplify written content was used including calculating readability statistics, applying the Patient Education Materials Assessment Tool, supplementing written information with video and audio content, and incorporating micro-learning and interactive quizzes. To develop communicative and critical health literacy skills, question prompt lists and evidence-based volitional help sheets were included in each module to support question-asking and behaviour change. We also developed animated skills training related to communication, shared decision-making and critical appraisal of health information.

CONCLUSIONS

This is the first health literacy informed app developed to promote active patient participation in CKD management and decision-making. Ongoing evaluation of the SUCCESS app through analysis of quantitative and qualitative data will provide valuable insights into the feasibility of implementing the app with dialysis patients, and the impact of the intervention of psychosocial and clinical outcomes. SO WHAT?: Digital health solutions have been found to improve self-management for chronic conditions, and could optimise the use of health care services and patient outcomes.

Effectiveness of an education intervention associated with an exercise program in improving disease-related knowledge and health behaviours among diabetes patients

OBJECTIVE

to assess the effectiveness of an education intervention associated with an exercise program in improving knowledge and health behaviours among diabetes patients.

METHODS

Diabetes and prediabetes patients were exposed to an evidence- and theoretically-based comprehensive education intervention over 24 weeks. Patients completed surveys assessing knowledge, physical activity, food intake, self-efficacy, and health literacy. Functional capacity was measured by oxygen uptake. All outcomes were assessed pre- and post-CR. Satisfaction about the education provided was assessed at post-CR. Paired t-tests, Pearson correlation coefficients, and linear regression models were computed to investigate the effectiveness of this intervention.

RESULTS

84 patients consented to participate, of which 47(56.0%) completed post-CR assessments. There was a significant improvement in patients' overall knowledge pre- to post-CR, as well as in physical activity, food intake, self-efficacy, and health literacy (p < 0.05). Peak VO₂ has clinically significant improved. Results showed a low significant positive correlation was between post-CR knowledge and food intake(r = 0.297;p = 0.04). Linear regression analysis revealed that age(B=-0.051; p = 0.01) was influential in changing post-CR knowledge.

CONCLUSION

The benefits of an education intervention designed for diabetes and prediabetes patients associated with an exercise program have been supported.

PRACTICE IMPLICATIONS

This work shows one effective education strategy taken in place that can be replicated in different settings.

Methods and Evaluation Criteria for Apps and Digital Interventions for Diabetes Self-Management: Systematic Review

BACKGROUND

There is growing evidence that apps and digital interventions have a positive impact on diabetes self-management. Standard self-management for patients with diabetes could therefore be supplemented by apps and digital interventions to increase patients' skills. Several initiatives, models, and frameworks suggest how health apps and digital interventions could be evaluated, but there are few standards for this. And although there are many methods for evaluating apps and digital interventions, a more specific approach might be needed for assessing digital diabetes self-management interventions.

OBJECTIVE

This review aims to identify which methods and criteria are used to evaluate apps and digital interventions for diabetes self-management, and to describe how patients were involved in these evaluations.

METHODS

We searched CINAHL, EMBASE, MEDLINE, and Web of Science for articles published from 2015 that referred to the evaluation of apps and digital interventions for diabetes self-management and involved patients in the evaluation. We then conducted a narrative qualitative synthesis of the findings, structured around the included studies' quality, methods of evaluation, and evaluation criteria.

RESULTS

Of 1681 articles identified, 31 fulfilled the inclusion criteria. A total of 7 articles were considered of high confidence in the evidence. Apps were the most commonly used platform for diabetes self-management (18/31, 58%), and type 2 diabetes (T2D) was the targeted health condition most studies focused on (12/31, 38%). Questionnaires, interviews, and user-group meetings were the most common methods of evaluation. Furthermore, the most evaluated criteria for apps and digital diabetes self-management interventions were cognitive impact, clinical impact, and usability. Feasibility and security and privacy were not evaluated by studies considered of high confidence in the evidence.

CONCLUSIONS

There were few studies with high confidence in the evidence that involved patients in the evaluation of apps and digital interventions for diabetes self-management. Additional evaluation criteria, such as sustainability and interoperability, should be focused on more in future studies to provide a better understanding of the effects and potential of apps and digital interventions for diabetes self-management.

Health Equity in the Effectiveness of Web-Based Health Interventions for the Self-Care of People With Chronic Health Conditions: Systematic Review

Background

Web-based self-care interventions have the potential to reduce health inequalities by removing barriers to access to health care. However, there is a lack of evidence about the equalizing effects of these interventions on chronic conditions.

Objective

This study investigated the differences in the effectiveness of web-based behavioral change interventions for the self-care of high burden chronic health conditions (eg, asthma, chronic obstructive pulmonary disease [COPD], diabetes, and osteoarthritis) across socioeconomic and cultural groups.

Methods

A systematic review was conducted, following Cochrane review guidelines. We conducted searches in Ovid Medical Literature Analysis and Retrieval System Online and Cumulative Index to Nursing and Allied Health Literature databases. Studies with any quantitative design were included (published between January 1, 2006, and February 20, 2019) if they investigated web-based self-care interventions targeting asthma, COPD, diabetes, and osteoarthritis; were conducted in any high-income country; and reported variations in health, behavior, or psychosocial outcomes across social groups. Study outcomes were investigated for heterogeneity, and the possibility of a meta-analysis was explored. A narrative synthesis was provided together with a novel figure that was developed for this review, displaying heterogeneous outcomes.

Results

Overall, 7346 records were screened and 18 studies were included, most of which had a high or critical risk of bias. Important study features and essential data were often not reported. The meta-analysis was not possible due to the heterogeneity of outcomes. There was evidence that intervention effectiveness was modified by participants’ social characteristics. Minority ethnic groups were found to benefit more from interventions than majority ethnic groups. Single studies with variable quality showed that those with higher education, who were employed, and adolescents with divorced parents benefited more from interventions. The evidence for differences by age, gender, and health literacy was conflicting (eg, in some instances, older people benefited more, and in others, younger people benefited more). There was no evidence of differences in income, numeracy, or household size.

Conclusions

There was evidence that web-based self-care interventions for chronic conditions can be advantageous for some social groups (ie, minority ethnic groups, adolescents with divorced parents) and disadvantageous for other (ie, low education, unemployed) social groups who have historically experienced health inequity. However, these findings should be treated with caution as most of the evidence came from a small number of low-quality studies. The findings for gender and health literacy were mixed across studies on diabetes, and the findings for age were mixed across studies on asthma, COPD, and diabetes. There was no evidence that income, numeracy, or the number of people living in the household modified intervention effectiveness. We conclude that there appear to be interaction effects, which warrant exploration in future research, and recommend a priori consideration of the predicted interaction effects.

Goal-Framing and Temporal-Framing: Effects on the Acceptance of Childhood Simple Obesity Prevention Messages among Preschool Children's Caregivers in China

A range of intervention models are available for childhood obesity prevention; however, few studies have examined the effectiveness of intervention messages. This study developed childhood simple obesity prevention messages on the basis of goal-framing and temporal-framing effects to improve message acceptance among the caregivers of preschool children and explored associated factors. A cross-sectional study was conducted among 592 caregivers of preschool children in urban kindergartens in China during March to April 2019. The framing messages were developed based on prospect theory and construal level theory. The majority (48.4%) of caregivers found the gain-framed, present-oriented message most salient for acceptance. We found that gender, education background, theme, and the use of negative words have impacts on goal-framing effects; and previous participation in a health related intervention, career category, and the theme have impacts on temporal-framing effects (p < 0.001). Goal-framing effects and temporal-framing effects can influence each other (p < 0.001). The findings suggest that the gain-framed, present-oriented message could be considered a strategy to improve the acceptance of information by caregivers. When framing a message, subtle differences like using negative words might affect the exertion of framing effects.

Effect of ecological momentary assessment, goal-setting and personalized phone-calls on adherence to interval walking training using the InterWalk application among patients with type 2 diabetes-A pilot randomized controlled trial

OBJECTIVES

The objective was to investigate the feasibility and usability of electronic momentary assessment, goal-setting and personalized phone-calls on adherence to a 12-week self-conducted interval walking training (IWT) program, delivered by the InterWalk smartphone among patients with type 2 diabetes (T2D).

METHODS

In a two-arm pilot randomized controlled trial (Denmark, March 2014 to February 2015), patients with T2D (18-80 years with a Body Mass Index of 18 and 40 kg/m2) were randomly allocated to 12 weeks of IWT with (experimental) or without additional support (control). The primary outcome was the difference between groups in accumulated time of interval walking training across 12 weeks. All patients were encouraged to use the InterWalk application to perform IWT for ≥90 minute/week. Patients in the experimental group made individual goals regarding lifestyle change. Once a week inquiries about exercise adherence was made using an ecological momentary assessment (EMA). In case of consistent self-reported non-adherence, the patients would receive a phone-call inquiring about the reason for non-adherence. The control group did not receive additional support. Information about training adherence was assessed objectively. Usability of the EMA was assessed based on response rates and self-reported satisfaction after 12-weeks.

RESULTS

Thirty-seven patients with T2D (66 years, 65% female, hemoglobin 1Ac 50.3 mmol/mol) where included (n = 18 and n = 19 in experimental and control group, respectively). The retention rate was 83%. The experimental group accumulated [95%CI] 345 [-7, 698] minutes of IWT more than the control group. The response rate for the text-messages was 83% (68% for males and 90% for females). Forty-one percent of the experimental and 25% of the control group were very satisfied with their participation.

CONCLUSION

The combination inquiry about adherence using EMA, goal-setting with the possibility of follow-up phone calls are considered feasible interventions to attain training adherence when using the InterWalk app during a 12-week period in patients with T2D. Some uncertainty about the effect size of adherence remains.

Association of health literacy and diabetes self-management: a systematic review

The purpose of this review is to summarise the existing evidence about the association of health literacy (HL) with type 2 diabetes mellitus self-management. The PubMed, Medline, CINHAL, Scopus and Web of Science databases were searched for randomised control trials of type 2 diabetes mellitus (T2DM) self-management and HL published between 2009 and 2018. Fourteen randomised control trials were included in this review. Our findings showed that HL was instrumental in improving diabetes knowledge, physical activity, self-efficacy and quality of life; however, its associations with glycaemic control, self-monitoring of blood glucose, foot care and medication adherence was inconclusive. Customized and community-based HL interventions were more efficient compared to patient-focused HL interventions. This review concludes that HL is key for T2DM self-management, but customised, structured and community-based interventions are more likely to yield better outcomes.

Identifying Health Literacy in Kansas Using the Behavioral Risk Factor Surveillance System

Health literacy continues to be an important research topic as part of population-based assessments for overall health issues. The objective of this continuation study was to examine the health literacy rates and health outcomes as measured by the Kansas Behavioral Risk Factor Surveillance System (BRFSS) survey. A cross-sectional research design was used. Health literacy data were extracted from the state-specific module of the BRFSS telephone survey. Demographic and health status variables were extracted from the core BRFSS dataset. The association between demographic and health status characteristics with health literacy was obtained using weighted samples in multivariable logistic regression models. As in the previous study, most respondents had moderate health literacy (61.1%), followed by high health literacy (31.4%) and low health literacy (7.5%). The demographic variables of interest included race, marital status, home ownership, insurance status, metropolitan status code, survey language, veteran status, education, employment, income, sex, and age. The health status variables included general health rating, presence of chronic conditions, and length of time since last check-up. Findings include individuals with low levels of health literacy were nearly 7 times as likely to be unsure of at least one health condition than those with high health literacy and demonstrate a broad gap in people’s ability to communicate accurate information to health-care providers. Results can inform future efforts to build programs that address health disparities issues including low health literacy to provide equitable health-care services. There is a continued need for support for the creation of health literate programs.

Evidence on the effectiveness of health literacy interventions in the EU: a systematic review

BACKGROUND

In the last decade, the attention for health literacy has increased in the European Union. This is due to three main reasons. First, reviews have shown that inadequate health literacy is associated with worse health outcomes, higher health care use and expenditure. Second, in all European countries the population is aging and the number of chronically ill people is rising. Improving health literacy in this group can offer greater opportunities to take an active part in society, be independent and improve quality of life. Third, since most research on health literacy has been conducted outside Europe and relatively little is known about the development of health literacy interventions and its effects on outcome measures in European countries. The aim of this systematic review was to assess the evidence on the effectiveness of health literacy interventions in the European Union published between 1995 and 2018.

METHODS

Searches have been performed in Medline, PubMed, EMBASE, CINAHL, Cochrane library, PsychINFO, ERIC, Web of Science and SCOPUS for publications on health literacy intervention studies in European Union countries. Studies were included if the research was conducted in one or more Member States of the European Union, the publication described an intervention study, the intervention was aimed at health literacy, the publication described an outcome measure related to health literacy and the publication was written in English, French or German.

RESULTS

A total of 23 studies were included. Three types of interventions were identified; aimed at improving health literacy, tailored to different health literacy levels and aimed at improving health outcomes in general that differentiated in effects for people with different health literacy levels. Most interventions identified in the review focus on the functional level of health literacy or numeracy. The strength of evidence from the European health literacy intervention studies was low and there was a huge heterogeneity in study design, measurement tools and outcomes measured.

CONCLUSIONS

Promising interventions were tailored to the needs of patients, addressing functional, interactive and critical skills and use not difficult animated spoken text. Future research should focus on the development and assessment of such interventions and use stronger designs.

Mutual Involvement in Families With Type 2 Diabetes Through Web-Based Health Care Solutions: Quantitative Survey Study of Family Preferences, Challenges, and Potentials

Background

Type 2 diabetes (T2D) is a prevalent chronic disease that affects not just patients but entire families. Both the patient and the rest of the family may benefit from gaining knowledge about the disease and from supportive interfamilial interaction. The Internet is becoming a widely-used resource for health information, so a Web-based solution could potentially promote awareness and knowledge on how to manage T2D as a family, while also providing support for the family.

Objective

We aim to assess the usage of online diabetes information by patients with T2D and their relatives, and explore the families’ needs and preferences regarding online information on diabetes.

Methods

A quantitative self-reported questionnaire survey was performed with Danish families that had at least one family member diagnosed with T2D. The survey consisted of 36 closed questions on demographics, usage of the Internet, preferences in the source of information, interest in online information on six problem domains within family life related to T2D, preferences towards the delivery format of online information, and peer-to-peer communication. Two open-ended questions were also included to elicit any additional comments or suggestions about improving online information on T2D regarding family life.

Results

Fifty participants from 22 families with T2D answered the questionnaire individually. Relatives (25/28, 89%) and patients (22/22, 100%) indicated that information on T2D is relevant for them, while indicating that the Internet is the first or second preferred source when in need of information on T2D (25/28, 89% vs 21/22, 95%). Only a minority of the participants indicated that they had searched the Internet to gain knowledge on T2D regarding family life (9/28, 32% vs 10/22, 46%). Also, patients were more likely to have used the Internet to gain information on T2D (P=.027). Both groups indicated a preference for watching videos or reading about T2D in relation to family life while a minority of the participants indicated an interest in peer-to-peer communication. Regarding the six problem domains, the domains Support, Knowledge, and Everyday Life were slightly more popular. These three domains were considered interesting by at least 79% (22/28) and 73% (16/22) of the relatives and patients respectively, while the domains Communication, Worries, and Roles were considered interesting by at least 46% (20/28) and 50% (11/22).

Conclusions

Despite an interest in online information on T2D, there appears to be an unsatisfied need for more supportive online information on T2D aimed at Danish families with T2D. Based on family preferences, online information should focus on the six problem domains and be presented through text and videos by health care practitioners and peers. Peer-to-peer communication elements may be beneficial, but are only expected to be used by a very limited number of families.

Telemonitoring and Health Counseling for Self-Management Support of Patients With Type 2 Diabetes: A Randomized Controlled Trial

Background

The prevalence of diabetes is increasing among adults globally, and there is a need for new models of health care delivery. Research has shown that self-management approaches encourage persons with chronic conditions to take a primary role in managing their daily care.

Objective

The objective of this study was to investigate whether the introduction of a health technology-supported self-management program involving telemonitoring and health counseling had beneficial effects on glycated hemoglobin (HbA_1c), other clinical variables (height, weight, body mass index, blood pressure, blood lipid profile), and health-related quality of life (HRQoL), as measured using the Short Form Health Survey (SF-36) version 2 in patients with type 2 diabetes.

Methods

This was a pragmatic randomized controlled trial of patients with type 2 diabetes. Both the control and intervention groups received usual care. The intervention group also participated in additional health promotion activities with the use of the Prescribed Healthcare Web application for self-monitoring of blood glucose and blood pressure. About every second month or when needed, the general practitioner or the diabetes nurse reviewed the results and the health care activity plan.

Results

A total of 166 patients with type 2 diabetes were randomly assigned to the intervention (n=87) or control (n=79) groups. From the baseline to follow-up, 36 patients in the intervention group and 5 patients in the control group were lost to follow-up, and 2 patients died. Additionally, HbA_1c was not available at baseline in one patient in the intervention group. A total of 122 patients were included in the final analysis after 19 months. There were no significant differences between the groups in the primary outcome HbA_1c level (P=.33), and in the secondary outcome HRQoL as measured using SF-36. A total of 80% (67/87) of the patients in the intervention group at the baseline, and 98% (47/50) of the responders after 19-month intervention were familiar with using a personal computer (P=.001). After 19 months, nonresponders (ie, data from baseline) reported significantly poorer mental health in social functioning and role emotional subscales on the SF-36 (P=.03, and P=.01, respectively).

Conclusions

The primary outcome HbA_1c level and the secondary outcome HRQoL did not differ between groups after the 19-month follow-up. Those lost to follow-up reported significantly poorer mental health than did the responders in the intervention group.
