The Long-Term Effectiveness of Internet-Based Interventions on Multiple Health Risk Behaviors: Systematic Review and Robust Variance Estimation Meta-analysis

Trust and Privacy Concerns Among Cancer Survivors Who Did Not Visit a Research Website Offering Free Genetic Counseling Services for Families: Survey Study

BACKGROUND

Digital health tools, such as websites, now proliferate to assist individuals in managing their health. With user input, we developed the Your Family Connects (YFC) website to promote access to genetic services for survivors of ovarian cancer and their relatives. Although we estimated that half or more would access the website, only 18% of invited survivors did so. We assessed the extent to which perceived relevance of the information provided, trust, and privacy concerns influenced decisions not to access the website.

OBJECTIVE

We designed a theory-based cross-sectional survey to explore the following questions: (1) To what extent did nonresponders endorse privacy concerns? (2) Were privacy concerns associated with recall of receiving the website invitation, time since diagnosis, age, and race? (3) Could we identify profiles of nonresponders that would guide the development of future interventions to encourage engagement in health websites for families affected by inherited cancers?

METHODS

A sample of survivors who were eligible to access the website yet did not respond to the study invitation was identified by linking study IDs to the Georgia Cancer Registry information. The survey was brief and contained 27 items, including recall of the invitation, interest in ovarian cancer information, benefits of using health websites, trust in health websites, and trust in university-based health research. We conducted factor analyses, regression analyses, ANOVA, correlation analyses, and logistic regression to address research questions.

RESULTS

Of the 650 nonresponders to whom we sent the short survey, 368 (56.3%) responded and provided sufficient data for analysis. The mean response of 2.57 on the trust scale was significantly below the scale midpoint of 3 (t360=11.78, P<.001), suggesting that survivors who did not log on were on average distrustful of health websites. Belonging to a racial or ethnic minority group was associated with being more trusting and less skeptical about health websites. Just 196 (30.1%) nonresponders recalled the invitation to visit the website. Logistic regression analysis indicated that age was the only significant predictor of recall. Testing a model with age, racial or ethnic minority status, and the 6 privacy concerns correctly classified 58.8% of nonresponders, a rate of successful classification that was not appreciably better than a logistic regression analysis that included only age as a predictor.

CONCLUSIONS

The nonresponders in the present study-particularly the White nonresponders-were skeptical of website platforms regardless of whether they recalled receiving a website invitation or not. Social marketing approaches geared toward building trust in web platforms by building a relationship with an information consumer and in collaboration with trusted organizations warrant further investigation.

Web-based interventions for treatment-seeking individuals with hazardous alcohol consumption: analysis of clinical characteristics and motives for abstinence

AIMS

This study compared individuals with hazardous alcohol consumption who used the web-based intervention "Ohne Alkohol mit Nathalie" (OAMN) with individuals who relied exclusively on traditional support to enhance the understanding of OAMN user characteristics.

METHODS

A cross-sectional online survey included 2460 treatment-seeking participants with Alcohol Use Disorders Identification Test scores ≥8 indicating hazardous alcohol use. The OAMN group (n = 1825) included individuals who had used OAMN programs, while the non-OAMN group (n = 635) relied exclusively on traditional support. Analyses compared sociodemographic characteristics, psychiatric comorbidities, the extent to which OAMN was used as a standalone or complementary tool, alcohol consumption, and abstinence motives.

RESULTS

Both groups were predominantly female and highly educated, but these characteristics were more pronounced among OAMN users. About one-third of OAMN users relied exclusively on the examined intervention, while two-thirds combined it with other forms of support. Non-OAMN users exhibited higher psychiatric comorbidities and had higher Alcohol Use Disorders Identification Test scores. Intrinsic motives were key drivers for abstinence in both groups, while these motives were more pronounced among OAMN users and extrinsic motives were more frequently reported by non-OAMN users.

CONCLUSION

These findings show that OAMN primarily attracts well-educated women and that it's used as both a standalone and complementary intervention. OAMN users were more likely to report intrinsic motives such as improving well-being and autonomy as key drivers for abstinence and less likely to report extrinsic motives such as external expectations and fear. These insights enhance understanding of the characteristics and abstinence motives of individuals engaging with OAMN.

Proactive automatized multiple health risk behavior change intervention: reach and retention among general hospital patients

Although behavior change interventions are highly recommended in health care, their reach, a core dimension of the public health impact of interventions, is rarely evaluated. This study aimed to investigate whether an individualized, computer-based brief intervention to reduce co-occurring health risk behaviors (HRBs), namely tobacco smoking, at-risk alcohol use, insufficient physical activity, and unhealthy diet, can reach and retain a sufficiently large part of general hospital patients (>75%) and whether patients with high need, that is with more HRBs, low school education or current unemployment may be sufficiently reached and retained. Over 6 weeks in 2022, all 18-64-year-old patients admitted to 11 wards of five medical departments of a university hospital in Germany were asked to participate in a computer-based HRB screening and in a pre-post intervention study with three further assessments and individualized computer-generated feedback. To investigate associations between intervention reach and retention and patient characteristics, a logistic and a Poisson regression analysis were used. Screening reached 78.9% of all eligible patients (225/285). Of those eligible for the intervention study, 81.8% (175/214) participated in the intervention. Among these, 76.0% (133/175) participated at least once more after hospitalization. Patients' lifestyle and socio-economic characteristics were not significantly associated with reach or retention, Ps ≥ .467. Proactive computer-based multiple-HRB change interventions may reach and retain a sufficiently large part of general hospital patients, including those most in need. When proven efficacious and adequately implemented, this is a promising approach concerning public health impact in the reduction non-communicable diseases.

Time-Use Sequences: A Mixed-Methods Study Exploring How, When, and Where Spatiotemporal Patterns of Everyday Routines Can Strengthen Public Health Interventions

BACKGROUND

Behavior change interventions are critical for the secondary prevention of cardiovascular disease and for reducing the risk of a repeat event or mortality. However, the effectiveness of behavior change interventions is challenged by a lack of spatiotemporal contexts, limiting our understanding of factors that influence the timing and location in which day-to-day activities occur and the maintenance of behavior change. This study explored how behavior change interventions could incorporate spatiotemporal contexts of patient activities for modifying behaviors.

METHODS

A mixed-methods approach with adapted geo-ethnography techniques was used to solicit detailed descriptions of patients' day-to-day routines, including where, when, and how patients spend time. Data were gathered from patients in one cardiac intervention program in Nova Scotia, Canada, from June to September 2021.

RESULTS

A total of 29 individuals (19 men and 10 women) between the ages of 45 and 81 and referred to the program after a cardiac event participated. The results show three key findings: (1) most patients exceeded the minimum guidelines of 30 min of daily physical activity but were sedentary for long periods of time, (2) patient time-use patterns are heterogenous and unique to contexts of individual space-time activity paths, and (3) time-use patterns reveal when, where, and how patients spend significant portions of time and opportunities for adapting patients' day-to-day health activities.

CONCLUSIONS

This study demonstrates the potential for interventions to integrate tools for collecting and communicating spatial and temporal contexts of patient routines, such as the types of activities that characterize how patients spend significant portions of time and identification of when, where, and how to encourage health-promoting changes in routine activities. Time-use patterns provide insight for tailoring behavior change interventions so that clinic-based settings are generalizable to the contexts of where, when, and how patient routines could be adapted to mitigate cardiovascular risk factors.

Assessing the Effectiveness of eHealth Interventions to Manage Multiple Lifestyle Risk Behaviors Among Older Adults: Systematic Review and Meta-Analysis

BACKGROUND

Developing adverse lifestyle behaviors increases the risk of a variety of chronic age-related diseases, including cardiovascular disease, obesity, and Alzheimer disease. There is limited evidence regarding the effectiveness of eHealth-based multiple health behavior change (MHBC) interventions to manage lifestyle risk behaviors.

OBJECTIVE

The purpose of this systematic evaluation was to assess the effectiveness of eHealth MHBC interventions in changing ≥2 major lifestyle risk behaviors in people aged ≥50 years.

METHODS

The literature search was conducted in 6 electronic databases-PubMed, Embase, Web of Science, Scopus, Cochrane Library, and SPORTDiscus-from inception to May 1, 2024. Eligible studies were randomized controlled trials of eHealth interventions targeting ≥2 of 6 behaviors of interest: alcohol use, smoking, diet, physical activity (PA), sedentary behavior, and sleep.

RESULTS

A total of 34 articles with 35 studies were included. eHealth-based MHBC interventions significantly increased smoking cessation rates (odds ratio 2.09, 95% CI 1.62-2.70; P<.001), fruit intake (standardized mean difference [SMD] 0.18, 95% CI 0.04-0.32; P=.01), vegetable intake (SMD 0.17, 95% CI 0.05-0.28; P=.003), self-reported total PA (SMD 0.22, 95% CI 0.02-0.43; P=.03), and objectively measured moderate to vigorous PA (SMD 0.25, 95% CI 0.09-0.41; P=.002); in addition, the interventions decreased fat intake (SMD -0.23, 95% CI -0.33 to -0.13; P<.001). No effects were observed for alcohol use, sedentary behavior, or sleep. A sensitivity analysis was conducted to test the robustness of the pooled results. Moreover, the certainty of evidence was evaluated using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) framework.

CONCLUSIONS

eHealth-based MHBC interventions may be a promising strategy to increase PA, improve diet, and reduce smoking among older adults. However, the effect sizes were small. Further high-quality, older adult-oriented research is needed to develop eHealth interventions that can change multiple behaviors.

Evaluation of a Primary E-Health Intervention for People with Alcohol Use Disorder: Clinical Characteristics of Users and Efficacy

In Germany, only about 10% of patients with alcohol use disorder (AUD) are treated by the professional help system. "The First 30 Days without Alcohol", an interactive e-health intervention, was developed to support people with "alcohol problems" to abstain from alcohol. The aim of this study was to examine the feasibility of the approach, the program's target group, if and why it is effective. In March 2022 an email was sent to all users who had completed the program. A link to a web-based survey regarding the target group's characteristics, its alcohol-use patterns, former attempts to change the problematic drinking behavior and experience with the program was introduced. The Alcohol Use Disorders Identification Test (AUDIT) was used prior and post intervention. A total of 718 participants completed the questionnaire. Of these, 99.2% suffered from AUD; 81.6% of participants were females, and about one third reported some form of psychiatric comorbidity; 46.6% did not use any additional help or assistance apart from the program; 78.3% reported to be abstinent after participation in the 30-day program, and the data show a significant AUDIT score reduction. Primary e-health interventions may contribute to the established addiction-help system. The intervention seems to reach predominantly highly educated and high-functioning females because of their characteristics.

Effectiveness of eHealth Interventions Targeting Employee Health Behaviors: Systematic Review

BACKGROUND

The number of people with noncommunicable diseases is increasing. Noncommunicable diseases are the major cause of disability and premature mortality worldwide, associated with negative workplace outcomes such as sickness absence and reduced work productivity. There is a need to identify scalable interventions and their active components to relieve disease and treatment burden and facilitate work participation. eHealth interventions have shown potential in clinical and general populations to increase well-being and physical activity and could be well suited for workplace settings.

OBJECTIVE

We aimed to provide an overview of the effectiveness of eHealth interventions at the workplace targeting employee health behaviors and map behavior change techniques (BCTs) used in these interventions.

METHODS

A systematic literature search was performed in PubMed, Embase, PsycINFO, Cochrane CENTRAL, and CINAHL in September 2020 and updated in September 2021. Extracted data included participant characteristics, setting, eHealth intervention type, mode of delivery, reported outcomes, effect sizes, and attrition rates. Quality and risk of bias of the included studies were assessed using the Cochrane Collaboration risk-of-bias 2 tool. BCTs were mapped in accordance with the BCT Taxonomy v1. The review was reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist.

RESULTS

In total, 17 randomized controlled trials met the inclusion criteria. The measured outcomes, treatment and follow-up periods, content of eHealth interventions, and workplace contexts had high heterogeneity. Of the 17 studies, 4 (24%) reported unequivocally significant findings for all primary outcomes, with effect sizes ranging from small to large. Furthermore, 53% (9/17) of the studies reported mixed results, and 24% (4/17) reported nonsignificant results. The most frequently targeted behavior was physical activity (15/17, 88% of the studies); the least frequently targeted behavior was smoking (2/17, 12% of the studies). Attrition varied greatly across the studies (0%-37%). Risk of bias was high in 65% (11/17) of the studies, with some concerns in the remaining 35% (6/17). Interventions used various BCTs, and the most frequently used were feedback and monitoring (14/17, 82%), goals and planning (10/17, 59%), antecedents (10/17, 59%), and social support (7/17, 41%).

CONCLUSIONS

This review suggests that, although eHealth interventions may have potential, there are still unanswered questions regarding their effectiveness and what drives the mechanism behind these effects. Low methodological quality, high heterogeneity and complexity, the characteristics of the included samples, and often high attrition rates challenge the investigation of the effectiveness and the making of sound inferences about the effect sizes and significance of the results. To address this, new studies and methods are needed. A megastudy design in which different interventions are evaluated in the same population over the same period on the same outcomes may solve some of the challenges.

Diet, Physical Activity, and Stress Among Wheelchair Users With Multiple Sclerosis: Examining Individual and Co-Occurring Behavioral Risk Factors

OBJECTIVE

This study examined individual and co-occurring behavioral risk factors (diet, exercise, and stress) in wheelchair users with multiple sclerosis (MS) and potential association with MS symptoms (ie, fatigue, depression, anxiety, pain, sleep, and health-related quality of life [HRQOL]).

DESIGN

Survey.

SETTING

General Community.

PARTICIPANTS

One hundred twenty-three wheelchair users with MS completed this study (N=123).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Participants were mailed instructions for accessing online questionnaires (demographic and clinical characteristics, Godin Leisure-Time Exercise Questionnaire, Perceived Stress Scale, Automated Self-Administered 24-Hour Dietary Assessment Tool, and MS symptoms).

RESULTS

Standard cut-points were used to categorize behavioral risk factors and then identify the extent and distribution of these behaviors both individually and co-occurring. We then analyzed the associations between behavioral risk factors and MS symptoms using bivariate correlation analyses and Mann-Whitney U tests. The mean age of participants was 60.6±10.0 years, 76% identified as women, 82% had a progressive disease course, and the mean MS duration was 23.0±9.7 years. Seven participants were classified as having 0 negative health behaviors, 41 participants had 1 negative health behavior, 49 participants had 2 negative health behaviors, and 26 participants had 3 negative health behaviors. The number of negative health behaviors was significantly correlated with HRQOL (physical, r=.30; psychological, r=.47), sleep (r=.25), depressive symptoms (r=.36), and anxiety (r=.43). Mann-Whitney U tests indicated greater fatigue, depression, and anxiety as well as lower sleep quality and HRQOL among participants who reported 2 or 3 behavioral risk factors compared with 0 or 1 behavioral risk factor.

CONCLUSIONS

Future research should examine the design and implementation of multiple health behavior change interventions targeting co-occurring behavioral risk factors among wheelchair users with MS.

Comparison of Motivational Short Interventions to Improve Smokers' Health Behavior (The COSMOS Study): A Pragmatic Cluster-Randomized Two-Arm Trial in General Practice

INTRODUCTION

Helping smokers to quit is an important task of general practitioners (GPs). However, achieving tobacco abstinence is difficult, and smokers who fail may still want to improve their health in other ways. Therefore, Swiss GPs developed a multithematic coaching concept that encourages health behavior changes beyond smoking cessation alone.

AIMS AND METHODS

To compare the effectiveness of such coaching with state-of-the-art smoking cessation counseling, we conducted a pragmatic cluster-randomized two-arm trial with 56 GPs in German-speaking Switzerland and 149 of their cigarette smoking patients. GPs were instructed in either multithematic health coaching or smoking cessation counseling. After 12 months, we compared their patients' improvements in cigarette consumption, body weight, physical inactivity, alcohol consumption, stress, unhealthy diet, and a health behavior of their own choice, using hierarchical logistic regression models and Fisher's exact and t tests.

RESULTS

Over 95% of all participants achieved clinically relevant improvements in at least one health behavior, with no difference between study arms (health coaching vs. smoking cessation counseling: aOR = 1.21, 95% CI = [0.03-50.76]; and aOR = 1.78, 95% CI = [0.51-6.25] after non-responder imputation). Rates of clinically relevant improvements in the individual health behaviors did not differ between study arms either (they were most frequent in physical activity, achieved by 3 out of 4 patients), nor did the extent of the improvements.

CONCLUSIONS

Multithematic health coaching and state-of-the art smoking cessation counseling were found to be comparable interventions, both in terms of smoking cessation success and, quite unexpectedly, their effects on other health behaviors.

IMPLICATIONS

The findings of our study suggest that in general practice, multithematic health coaching is an effective smoking cessation intervention, and conversely, monothematic smoking cessation counseling also achieves the beneficial effects of a multithematic health behavior intervention. This opens up the possibility for GPs to support their smoking patients in improving their health behavior in additional and more flexible ways.

[Acceptance and use of web-based interventions for alcohol abstinence]

INTRODUCTION

In Germany, the prevalence rates for alcohol use disorders amount to approx. 6%, while about 3% are diagnosed as being alcohol dependent. Only 10% of the patients are undergoing treatment. There are apparent deficits with respect to early interventions. The internet presence of "Ohne Alkohol mit Nathalie" (OAmN) (Abstinence with Nathalie) ameliorates options for early treatment interventions using a web-based design; however, this intervention has not been evaluated to date, especially with respect to previous treatments.

METHODS

Over a 4-week period, 4 different channels of OAmN posted announcements for a survey participation introducing a link leading to a web-based survey questionnaire on the domain oamn.jetzt. The questionnaire offered open and closed as well as multiple choice questions regarding alcohol use patterns and attempts to change the problematic drinking behavior.

RESULTS

Out of 2022 participants 84.3% (n = 1705) stated to have or have had a problem with alcohol use, 17.7% (n = 302) had a diagnosis of alcohol dependence by a physician or psychologist and only 21% (n = 529) had been in therapy before. The majority of responders (85.5%, n = 1457) had stopped alcohol use before participating in the survey. Most of them (48.5%, n = 705) were assisted by OAmN, 97.5% (n = 1662) had been employed while having the abovementioned problem use of alcohol, 34.3% (n = 570) rated their job performance as "very good" and 43.2% (n = 718) as "good".

DISCUSSION

This pilot study revealed that OAmN can reach people affected by problematic drinking behavior who had not been in contact with the professional medical system for addiction treatment despite having a problematic alcohol use combined with the willingness to quit.

Barriers and Facilitators to Participation in Health Screening: an Umbrella Review Across Conditions

Screening is an essential prevention practice for a number of health conditions. However, screening coverage remains generally low. Studies that investigate determinants of screening participation are becoming more common, but oftentimes investigate screening for health conditions in an individualized rather than integrated fashion. In routine clinical practice, however, healthcare professionals are often confronted with situations in which several screening procedures are recommended for the same patient. The consideration of their common determinants may support a more integrated screening approach. The objectives of this umbrella review were therefore to examine: 1) the determinants (barriers and facilitators) that have been identified in relation to recommended health screening procedures; and 2) the modifiable determinants (in primary care) common across health conditions or specific to individual procedures. Results were presented through a narrative synthesis. PubMed, PsycInfo and Cochrane were searched up to January 2022. Systematic reviews reporting determinants of participation in health screening procedures with grade A or B recommendation according to the US Preventive Services Task Force were included. A total of 85 systematic reviews were included, most which contained both qualitative and quantitative studies on determinants that describe individual factors (961 occurrences), social factors (113 occurrences, healthcare professional factors (149 occurrences), health system factors (105 occurrences) and screening procedure factors (99 occurrences). The most studied screening procedures concerned cervical cancer/human papillomavirus (n = 33), breast cancer (n = 28), colorectal cancer (n = 25) and the human immunodeficiency virus (n = 12). Other conditions have been under-studied (e.g. cardiovascular problems, lung cancer, syphilis). The individual domain, including determinants such as knowledge, beliefs and emotions, was the most covered across health conditions. Healthcare professional's recommendations and the quality of patient-provider communication were identified to have a strong influence on screening participation in most conditions. The other three domains included determinants which were more specific to a condition or a population. Various determinants modifiable in primary care were found in the individual domain and in the health system, healthcare professional and screening procedure domains. Quality was assessed as low for most systematic reviews included. The identification of various modifiable determinants common across conditions highlights the potential of an integrated screening participation approach. Interventions may address common determinants in a broader person-centred framework within which tailoring to specific procedures or populations can be considered. This approach needs to be explored in intervention studies. The systematic review registration is PROSPERO CRD42019126709.

Tailoring Can Improve Consumers’ Hygienic Food-Handling Behavior to Reduce the Transmission Risk of Antimicrobial-Resistant Bacteria through Food

Antimicrobial-resistant (AMR) bacteria spread via food to humans and can seriously impair infection treatment. Hygienic food handling is an effective measure to avoid the transmission of bacteria. Therefore, we tested three types of interventions (tailored, generic, and no intervention) for their effectiveness in improving consumers’ hygienic food handling against the spread of antimicrobial-resistant bacteria through foods in a longitudinal randomized control trial. We based the determinants of hygienic food-handling behavior on the Health Action Process Approach (HAPA). The tailored intervention raised self-reported hygienic food handling, self-efficacy, and perceived likelihood of risk compared to no intervention. Moreover, interventions yielded different effects for participants with high vs. low intentions to improve their food-handling behavior. However, there were no differences between the tailored and generic interventions. More research is needed to find out whether including other behavior change techniques in the tailored intervention may increase the effect of tailoring.
