Health promotion and disease prevention with digital technologies for older people: Scoping review

Background

In the aging world digital technologies are needed to target the health needs of older people. This study aimed to identify digital technologies for health promotion and disease prevention for older people by performing a scoping review.

Methods

A search of MEDLINE, PsycINFO, CINAHL and SCOPUS on 09.03.2022 identified 2150 studies. The inclusion criteria were: 1) Population: older people, 2) Concept: any digital health technology, 3) Context: health promotion and disease prevention in home or community settings. Preliminary study selection was performed automatically using the smart groups function in EndNote. Studies were clustered by digital technology type, health target, study design and study focus. Final study selection and data coding will be performed manually by two authors.

Results

Of the 2150 studies, 1874 studies were excluded, 159 studies met the inclusion criteria 1) and 2), but addressed different contexts (digital competence, digital technology development, disease management) or setting (care) and 117 studies were included. Digital technology types were: 1) any technologies (digital, virtual, video, eHealth or telehealth), 2) internet websites accessed via computer, 3) SMS or mobile phones, 4) exergaming or 5) smartphones or wearables. Health targets were: 1) physical activity, 2) mental health and wellness, 3) nutrition or 4) cognitive functioning. Study designs included primary studies (randomized-controlled trials) or reviews (systematic or scoping). Study focus was on effectiveness, feasibility or evaluation of digital technologies.

Conclusions

The health needs of older people are addressed by older technologies. Newer studies use heterogeneous terminology when referring to digital technologies. Future studies should focus on multiple aspects of healthy aging beyond mobility. More work is also needed to understand if and how a shift towards newer technologies occurs and if that is associated with health benefits in older people.

Key messages

• Older digital technologies (computers and mobile phones) address the health needs of older people.

• Mobility is the main health target of digital technologies for older people in the context of health promotion and disease prevention.

Highlighting the ‘public ‘in digital public health – a critical reflection

What is the appropriate differentiation of digital public health versus digital health - or is there none? This is an essential question when pondering digitalisation and public health, especially with a view to the potential development of the field. Digital health seems to be a general term related to information and communication technology in health care. Putting a public health lens on this general descriptive term can be done by simply expanding it towards public health as a population science and practice field, rather than the narrow medical and health care arena. However, a more specific approach towards outlining similarities and differences will also focus on digital technologies and their challenges in the core areas of prevention and health promotion. Considering the leading public health functions, their relationship with digitalisation and their specific requirements towards digitalisation can be a valuable path to describe and discuss what digital public health is all about. We will also highlight where interfaces and interrelations with digital health need to be considered for research and practice. This contribution will aim to provide such a perspective.

Scoping Review of Existing Evaluations of Smokeless Tobacco Control Policies: What Is Known About Countries Covered, Level of Jurisdictions, Target Groups Studied, and Instruments Evaluated?

OBJECTIVE

The implementation of smokeless tobacco control policies lags behind those for smoking. This scoping review summarizes the studies that evaluated public policies on smokeless tobacco regulation (SLT) and provides an overview of the jurisdictional level, target groups, and policy instruments.

METHODS

Seven databases were systematically searched for studies reporting on public policies regulating SLT. Two reviewers independently screened all studies. Data extraction was performed using a predefined extraction form. Extraction was replicated for 10% of the identified studies for quality assurance. A narrative synthesis of the included studies was used to analyze and interpret the data. The protocol was published beforehand with the Open Science Foundation (OSF).

RESULTS

Fourty articles comprising 41 studies were included. Most of the studies reported in the articles were conducted in the United States (n = 17) or India (n = 14). Most studies reported outcomes for students (n = 8), retailers/sellers (n = 8), and users/former users (n = 5). The impact of public policies on smokeless tobacco use, in general, was most frequently assessed (n = 9), followed by the impact of taxes (n = 7), product bans (n = 6), sales/advertising bans near educational institutions (n = 4), and health warnings (n = 3) on consumer behavior.

CONCLUSIONS

There are significant gaps in the evaluation of smokeless tobacco regulation studies that need to be filled by further research to understand the observed outcomes. WHO reporting on Framework Convention on Tobacco Control (FCTC) implementation should be linked to studies evaluating smokeless tobacco control measures at all levels of jurisdictions and in countries not members of the WHO FCTC or do not provide data.

IMPLICATION

Large gaps in the evaluation of SLT control policies exist. For some countries, WHO FCTC evaluations are available for different levels of jurisdictions. In countries with a strong federal structure, there is a lack of data beyond the national level to provide a more detailed look at compliance, indirect effects, or implementation gaps. More research is needed at all levels of jurisdictions, which add to the work of the WHO to understand what works for which target group, how the different levels of jurisdiction interact, how the real-world context can be incorporated, and what indirect effects may occur.

Depressive symptoms in higher education students during the first wave of the COVID-19 pandemic. An examination of the association with various social risk factors across multiple high- and middle-income countries

Higher-education students face substantial risks for developing depressive symptoms during the COVID-19 pandemic or experiencing exacerbated pre-existing depressive symptoms. This study uses data from the COVID-19 International Student Well-Being Study, which collected data through a non-representative convenience sample in 125 higher-education institutions (HEI) across 26 high- and middle-income countries (N: 20,103) during the first wave of the COVID-19 pandemic. It describes the prevalence of depressive symptoms in higher-education students. We find substantial cross-national variation in depressive symptoms, with lowest mean levels established in the Nordic countries and France, while highest mean levels of depressive symptoms were found in Turkey, South Africa, Spain and the USA. Elevated risk for depressive symptoms was found in female students, students with fewer social support resources and in a more disadvantaged socioeconomic position, and students with a migrant background. COVID-19 related stressors, such as reduced social contact, increased financial insecurity, and academic stress explained a relatively larger proportion of the variance in depressive symptoms compared to non-COVID-19 related stressors. This finding shows that not the pandemic itself, but rather the secondary effects of the pandemic relate to students' mental health. Our results enable HEIs to be better equipped to target groups that are particularly at risk during a pandemic.

Digital Health Literacy – results of a representative survey among adults in Germany

 

Whereas the concept of health literacy has already found its place in Public Health, this is less the case for digital health literacy (DiHL). To investigate the distribution of digital health literacy in the German adult population, we used a definition encompassing individual, social and technical competencies and resources to search, find, understand, apply and evaluate digital health information. We conducted a representative survey including 8.500 persons aged 18-75 years, based on an online access panel. All participants filled a questionnaire which covered the seven domains of the Digital Health Literacy Instrument (DHLI). Demographic information for participants was available through existing panel data. Optimal cut points to categorize digital health literacy were developed via regression modelling. Data were analysed using descriptive statistics and logistic regression modelling, comparing the two lower categories of DIHL against high/very high DiHL. Results are presented via odds ratios and 95% confidence intervals. Overall, 52.4% of respondents were categorized as having low or moderate DiHL (W: 51.2%; M: 53.7%). There were few differences according to age group and migration status. Those with higher educational attainment also scored higher in terms of DiHL. Operative competencies were generally rated high, whereas the evaluation of reliability of content scored lowest. In the regression analysis, the adjusted odds ratio (OR) for limited DiHL was 2.01 (95%CI 1.51;2.67) among those with poor or very poor self-reported health. Digital health literacy addresses a complex set of competencies and resources. More than half of the adult German population report a limited digital health literacy according to this nationwide survey. Impaired health is associated with low digital health literacy, and many have difficulties assessing the reliability of digital content. This is troublesome as more and more health-related information becomes digitalized.

Key messages

More than half of the German adult population reports limited digital health literacy. Poor health status was found to be associated with low digital health literacy.

Digital health literacy and COVID-19 pandemic: Results of a nationwide survey in Germany

Background

Digital health literacy is important for interpreting information and making health decisions in an increasingly digitised world. We investigated the perceived digital health literacy and the attitudes towards digital information on the COVID-19 pandemic using a nationwide survey.

Methods

We conducted a cross-sectional, computer-assisted telephone survey in October 2020 using a panel sample of Internet users selected from the general population living in Germany. Responses on items regarding the COVID-19 pandemic and the eHealth Literacy Scale (eHEALS; total sum score of 8=minimum to 40=maximum perceived digital health literacy) were analysed using descriptive statistics and a linear regression analysis.

Results

Of the 1014 Internet users, 928 (92%) completed the eHEALS. The respondents were 52% female, aged 14-93 years (mean±SD of 55±17 years), 66% with up to secondary education and 45% with up to average household income. The responses on eHEALS were consistent (Cronbach's α=.88). While the perceived digital health literacy was high (mean±SD eHEALS score of 31±6), less than half of respondents (43%) were confident in using digital information for health decisions. Higher digital health literacy was associated with younger age (β=-.22, p<.001), higher household income (β=.21, p<.001) and more education (β=.14, p<.001). About half of respondents (52%) reported that they sometimes or often come across inaccurate digital information on the COVID-19 pandemic. The majority (78%) were confident in their ability to recognise inaccurate digital information on the COVID-19 pandemic and 43% installed the contact-tracing app.

Discussion

Internet users in Germany report high perceived digital health literacy but low confidence in making health decisions and low trust in digital information on the COVID-19 pandemic. Factors contributing to such low confidence in the general population need to be investigated.

Key messages

Despite high digital health literacy, the confidence in making health decisions is low in the general public.

The trust in digital information on the COVID-19 pandemic is low.

Data Stewardship. A new health profession for findable, accessible, interoperable and re-usable data

Issue

In longstanding tradition of Public Health exists a tension between different stakeholders. Consensus about policies and practices is required to cope with the challenging transformation that results from digitalisation. For health systems, this means a new ‘way of digital thinking', especially in research data management (RDM). In Germany, NFDI4Health, an upcoming national research data infrastructure has the potential to shape this process. Its aim is making personal and health-related research data more findable, accessible, interoperable, and re-usable (FAIR). This vision is inspired by the German Council for Scientific Information Infrastructures.

Description of the problem

Health-related research data are sensitive and related to several legal restrictions. Therefore, it is particularly necessary to accompany these ‘living data bodies' during their entire life cycle. Due to various opt-in or opt-out models, access and re-use may change during and after the studies. This could only be circumvented by an unlimited, irrevocable and non-purposive approval by the data donor. The consequence is a tension between individual needs and the requirements of research.

Results

“Data Stewards” (DS) operate within a Task Area of NFDI4Health. In this context, they act as ‘agents of change' and as ‘boundary spanners' in a complex intervention; they tare individual and societal, legal and technical aspects in the field of research. A preliminary success of NFDI4Health is the integration of a DS in selected projects of a centre for clinical trials. The first milestones were to sensitize the study directors to the benefits of this intervention and to formally involve the DS.

Lessons

The concept of DS embedded in NFDI4Health is innovative and could serve as a model for Public Health worldwide. Clinical trials require tailored RDM, which can be provided by DS. They have the potential to integrate individual and social aspects to make “health-related big data” FAIR.

Key messages

Data Stewardship is an up-coming supporting profession for Public Health, which can help to create a “Big Picture” for more health in all policies. Data Stewardship is facing the task to handle health-related big data and to guide researchers in this field to adapt their techno-ethical work practices in the context of the digital transformation.

Mental wellbeing and engagement in health risk behaviours in German university students during the COVID-19 pandemic: Findings of a cross-sectional study

Background

Daily life of higher education students across the world changed profoundly in 2020 with the implementation of governmental and institutional measures to control the COVID-19 pandemic. We investigated mental wellbeing and engagement in health risk behaviours (HRB) in German university students at the start of the COVID-19 pandemic.

Methods

Data stem from the COVID-19 International Student Wellbeing Study (C19 ISWS). The web-based survey was conducted in May 2020 at four German universities. HRBs included tobacco and cannabis use, alcohol consumption, and engagement in physical activity. All HRBs were assessed retrospectively and at the time of data collection. Mental wellbeing was assessed using the 8-item Center for Epidemiologic Studies-Depression Scale (CES-D 8). We conducted multinomial regression analyses to investigate factors associated with changes in HRBs and latent transition analysis to identify substance use profiles.

Results

5021 students completed the survey (69% female; mean age 24.4 years, SD = 5.1). The mean score for depressive symptoms was 9.25 (SD = 0.67, range 0-24). Sixty-one percent of students reported consuming alcohol, 46% binge drinking, 44% inactivity, 19% smoking and 11% cannabis use. While smoking and cannabis use remained unchanged during the COVID-19 pandemic, 24% reported a decrease in binge drinking. Changes to physical activity were frequently reported, with 31% reporting an increase and 19% reporting a decrease in vigorous physical activity. Higher depressive symptoms were found to be associated with changes in HRBs. Five substance use behaviour profiles were identified, which remained fairly unchanged.

Conclusions

Engagement in HRBs remains at high level during the COVID-19 pandemic among German students. Depressive symptoms were found to be associated with changes in HRBs. Efforts to promote student health and wellbeing are needed in times of the COVID-19 pandemic and thereafter to prevent longer-term consequences.

Health literacy needs among unemployed adults: Triangulating interview and scoping review data

 

Disadvantaged populations, including unemployed adults, often exhibit low levels of health literacy. Exploring subjectively perceived health literacy needs in these populations can serve as an entry point for participatory intervention development. We aimed to assess health literacy needs of unemployed adults by triangulating qualitative interviews data and a scoping review. Using a parallel approach, we combined results of an interview study with 10 participants of a job-reintegration program in Germany and a scoping review. The interviews, conducted in early 2021, focused on health topics of interest to the participants and their sources of health-related information. Data were analysed using thematic analysis. For the scoping review, we searched MEDLINE, CINAHL, PsycInfo and SCOPUS up to January 2021 for studies containing “unemployed” AND “health literacy” in titles/abstracts. Study selection and data extraction were done independently by two researchers. Nutrition and physical activity emerged as core themes during the interviews, with some participants referring to the importance of both for mental health. Doctors and the institution running the job-reintegration program were the sources of health-related information often mentioned. The Corona pandemic was reported to have limited physical activity and affected psycho-social well-being. Five out of 2696 studies were included in the review. Four focused on mental health literacy, the fifth assessed information seeking practices in unemployed adults. The qualitative analysis revealed that health literacy needs of unemployed adults go beyond mental health literacy. As nutrition and physical activity impact mental health, interventions targeting such topics might also improve mental health literacy in unemployed adults. Study findings will be discussed with unemployed persons and social workers in co-production workshops that aim to identify and prioritize health literacy needs for intervention development.

Key messages

Health literacy programs for unemployed adults should target nutrition and physical activity. Workforce re-integration programs play a pivotal role in improving health literacy of unemployed adults.

Effects of a Brief Web-Based "Social Norms"-Intervention on Alcohol, Tobacco and Cannabis Use Among German University Students: Results of a Cluster-Controlled Trial Conducted at Eight Universities

Background and Aim: "Social norms" (SN)-interventions are aimed at changing existing misperceptions regarding peer substance use by providing feedback on actual norms, thereby affecting personal substance use. It is unknown whether SN-intervention effects previously demonstrated in US students can be replicated in German students. The aim of the INSIST-study was to examine the effects of a web-based SN-intervention on substance use. Design: Cluster-controlled trial. Setting: Eight Universities in Germany. Participants and Measurements: Students were recruited at four intervention vs. four delayed intervention control Universities. 4,463 students completed baseline, 1,255 students (59% female) completed both baseline and 5-months follow-up web-based surveys on personal and perceived peer substance use. Intervention participants received feedback contrasting personal and perceived peer use with previously assessed use and perceptions of same-sex, same-university peers. Intervention effects were assessed via multivariable mixed logistic regression models. Findings: Relative to controls, reception of SN-feedback was associated with higher odds for decreased alcohol use (OR: 1.91, 95% CI 1.42-2.56). This effect was most pronounced in students overestimating peer use at baseline and under or accurately estimating it at follow-up (OR: 6.28, 95% CI 2.00-19.8). The OR was 1.33 (95% CI 0.67-2.65) for decreased cannabis use in students at intervention Universities and was statistically significant at 1.70 (95% CI 1.13-2.55) when contrasting unchanged and decreased with increased use. Regarding tobacco use and episodes of drunkenness, no intervention effects were found. Conclusions: This study was the first cluster-controlled trial suggesting beneficial effects of web-based SN-intervention on alcohol and cannabis use in a large sample of German University students. Clinical Trial Registration: The trial registration number of the INSIST-study is DRKS00007635 at the "German Clinical Trials Register."

Nudging to move: a scoping review of the use of choice architecture interventions to promote physical activity in the general population

Background

Nudges are used to alter lifestyles and thus curb the rise of non-communicable diseases. Physical activity is a core prevention strategy to reduce the burden of non-communicable diseases. This paper aims to (1) give an overview of the scope of interventions using choice architecture techniques to promote physical activity at the population levels and (2) identify research gaps by analysing the different approaches in terms of class and type of intervention used.

Methods

A systematic electronic database search was combined with snowball citation sampling of a starter set of publications to search for studies published through October 2018 reporting interventions to promote physical activity at the population level using choice architecture techniques. The methodology of the Joanna Briggs Institute for Scoping Reviews was applied.

Results

In all, 35 publications were included. Most of the interventions used point-of-choice prompts tested at railway stations, shopping malls and airports (N = 27). Eight studies were online studies. While all studies were aimed at the general population, details, if reported at all, were vague and basic. All studies focused on individual-level lifestyle behaviour. None of the studies attempted to alter population-based lifestyle behaviour. Online and “real-world” approaches were rarely combined. Neither, interventions targeting meso- and macro-level structures nor combinations of individual-level and specific meso- or macro-level interventions were found.

Conclusion

Nudging is in principle an effective approach to promote physical activity within the general population. However, there are large gaps in research. Available opportunities have not yet been exhausted. Further research is needed that is explicitly based on behavioural insights and covering the full range of nudging approaches, particularly focussing on theoretical developments, practical feasibility tests and scale-up activities.

[Skin cancer screening and treatment costs : Utilisation of the skin cancer screening and skin cancer treatment costs in organ transplant recipients]

BACKGROUND

Organ transplant recipients have an up to 250-times higher risk to develop skin cancer. This article evaluated the utilisation of skin cancer screening and the treatment costs for skin cancer in organ transplant recipients. Patients of the health insurance AOK Bremen/Bremerhaven had been identified and the need for skin cancer prevention trainings was derived.

METHODS

The number of organ transplant recipients (ICD code Z94.0-4) with and without any history of skin cancer (ICD code C43/C44), the utilisation of dermatologic health care services, and the costs for treatments with the diagnosis Z94.0-4 with and without C43/C44 were evaluated. The analyses were carried out for the period from 2009-2014 by using the accounting systems of the AOK.

RESULTS

Between 2009 and 2014, 231 organ transplant recipients had been recorded. By mid-2014, 20% of these insured persons developed skin cancer and the mean incidence was 2.76% per year. On average, 43% of these patients were seen by a dermatologist at least once a year, whereby only 15% of the organ transplant recipients participated in the annual skin cancer screening. In 29% of the patients without any history of skin cancer, a skin examination was never performed by a dermatologist or a general practitioner. In all, 17 inpatient cases of organ transplant recipients with the primary diagnosis C43/C44 were analyzed. This resulted in total costs of 54,707 € (on average about 3200 € per case).

CONCLUSIONS

The increased incidence of skin cancer and the associated treatment costs indicate the need for skin cancer prevention training.

The effects of iodine blocking on thyroid cancer, hypothyroidism and benign thyroid nodules following nuclear accidents: a systematic review

A potential radiation protection method to reduce the risk of adverse health outcomes in the case of accidental radioactive iodine release is the administration of potassium iodide (KI). Although KI administration is recommended by WHO's Guidelines for Iodine Prophylaxis following Nuclear Accidents, a systematic review of the scientific evidence for the guidelines is lacking. Therefore, this study aims to systematically review the effects of KI administration in the case of accidental radioactive iodine release on thyroid cancer, hypothyroidism and benign thyroid nodules. We applied standard systematic review methodology for a search of the literature, selection of eligible studies, data extraction, assessment of risk of bias, assessment of heterogeneity, data synthesis, and the assessment of the quality of the evidence. We searched MEDLINE (via PubMed) and EMBASE. We found one cross-sectional study, one analytic cohort study and two case-control studies relating to our question. The number of participants ranged from 886-12 514. Two studies were conducted in children and two other studies in children and adults. It was not possible to conduct a meta-analysis. We identified low to very low-quality evidence that KI administration after a nuclear accident resulted in a reduction of the risk of thyroid cancer in children; however, the KI administration and dose was not well described in the studies. None of the studies investigated the effects of KI administration in the case of a nuclear accident on hypothyroidism and benign thyroid nodules. Low to very low-quality evidence suggests that KI intake following a nuclear accident may reduce the risk of thyroid cancer in children. No conclusions can be drawn about the effectiveness of KI intake with respect to the prevention of hypothyroidism and benign thyroid nodules.

[Tobacco Use and Utilization of Medical Services in Adolescence: An Analysis of the KiGGS Data]

OBJECTIVE

In Germany, there is a lack of information on the correlation between tobacco use by adolescents and their utilization of medical care. The aim of this article is to identify possible early consequences of adolescent smoking.

METHODS

We conducted a re-analysis of cross-sectional data of the baseline wave (2003-2006) of the German Health Survey for Children and Adolescents (KiGGS). To examine the association between current smoking status and utilization of medical care during the 12 months before the interview, prevalence of selected diseases was calculated, and stratified by smoking status. Besides, the proportion of adolescents who consulted a physician at least once and the total number of medical consultations were estimated. For the inpatient setting, information about the number of nights spent in a hospital was analyzed. In a multiple logistic regression, the association of smoking behavior with utilization of outpatient medical care was assessed, further adjusting for sociodemographic variables and comorbidities.

RESULTS

The study population included 3 679 adolescents aged between 14 and 17 years. 49.1% were female and 31.7% were current smokers. Among smokers, there was an increased prevalence of cystitis (+87.0%) and bronchitis (+50.0%). Tobacco users consulted a general practitioner more frequently than non-smokers (+30.8%). As far as medical specialists are concerned, there were more consultations with psychiatrists (+171.4%) and psychologists (+94.4%), but there was no increase in the total number of visits. Additionally, smoking adolescents were more frequently hospitalized (+26.5%) and the stays were of longer duration (+19.7%). There was a statistically significant association between current tobacco use and a greater utilization of medical care (OR=1.20; 95%-CI: 1.02-1.40).

CONCLUSIONS

Tobacco use among adolescents was associated with increased prevalence of certain diseases and a greater utilization of medical care. Nevertheless, whether there is a causal connection is still debatable. The KiGGS cohort study will provide opportunities to further clarify the observed association.

[Public Health: Setting Goals, Establishing Structures and Improving Health for All]

Public health is a population- and system-based approach that is needed to improve the health of societies and to decrease health inequalities. In the face of global challenges, the public health approach is essential. In Germany, the importance of public health is only partly reflected by its institutions and institutional arrangements. This applies equally to research, teaching and training, as well as to the public health service. Furthermore, the public health perspective is not sufficiently considered in cross-sectional topics that are relevant for health.There have been several initiatives to overcome structural deficits which can partly be traced back to historical circumstances. The White Paper presented here should encourage discussions about future policy options in public health. The authors represent public health in practice, research, and teaching in Germany.

[Effectiveness of School-based Interventions for the Prevention and/or Reduction of Psychosocial Problems among Children and Adolescents: A Review of Reviews]

Objective: To summarize the current evidence on the effectiveness of school-based interventions for the maintenance of mental health and the prevention of psychosocial problems among pupils. Methods: A systematic literature search of reviews published between 2007 and 2015 was carried out. Databases searched included Medline, PsycINFO, Campbell Library, Cochrane Library, NICE, ERIC, and Web of Science. Study selection, data extraction, and quality assessment (using AMSTAR criteria) were performed by 2 independent reviewers. Results: 6 reviews covering 331 primary studies were included in this review of reviews. Findings of three reviews with a focus on the maintenance and/or promotion of mental health and general well-being suggested that interventions aimed at changes in the social and the school environment were more effective than those that only targeted individual behavior change among pupils. Interventions for the reduction of mobbing/bullying were most effective if they comprised organizational changes at schools, such as playground and schoolyard supervision, and disciplinary measures. One review suggested strong evidence for the effectiveness of classroom management to reduce violent behavior among pupils. Conclusions: Participation in interventions promoting changes in the school environment, in addition to individual behavior change, appears to be associated with improved mental health among pupils and reductions in mobbing/bullying and violent behavior at schools.
