The impacts of a mHealth platform-enabled lifestyle-integrated multicomponent exercise program on reversing pre-frailty in community-dwelling older adults: A randomized controlled trial

BACKGROUND

Multicomponent exercise has robust evidence supporting their effectiveness in preventing pre-frailty/frailty. However, a generalizable model for managing frailty through exercise in real-world settings is still not well defined. A promising approach is to incorporate exercise into daily life. We have developed a lifestyle-integrated multicomponent exercise program supported by a mHealth platform. The objective of this research was to assess its effectiveness and elucidate its potential mechanisms for reversing pre-frailty in community-dwelling older adults.

METHODS

In this prospective, two-arm parallel randomized controlled trial, 134 pre-frail older adult were enrolled from the Fujian Prospective Ageing Cohort. Participants were randomly assigned to either the intervention group (integrating multicomponent exercise into daily life through a mHealth platform) or control group (health education). The primary outcome was the proportion of participants exhibiting pre-frailty after a 6-month intervention. Secondary outcomes included changes in functional fitness, body composition, bone mineral density, physical activity, and sedentary behavior.

RESULT

Of the 134 participants, 52 (77 %) from the intervention group and 54 (81 %) from the control group completed the study. After 6 months, the proportion of pre-frailty was significantly lower in the intervention group compared to the control group (32.8 % vs 98.5 %, P < .001). Improvements were observed in all five frailty components, except for unintentional weight loss. The intervention group also demonstrated significant enhancement in functional fitness, bone mineral density, and body composition (P < .05). Additionally, the intervention group experienced a decrease in sedentary time and an increase in light physical activity, although there was no statistically significant difference in moderate-to-vigorous physical activity.

CONCLUSION

The lifestyle-integrated multicomponent exercise program, facilitated through a mHealth platform, shows promising beneficial effects on reversing pre-frailty, improving functional fitness and body composition, and decreasing sedentary behavior in community-dwelling older adults.

The Mediating Effects of Symptom Experiences on the Relationship between Body Image and Quality of Life among Hemodialysis Patients in a Single Center

This study aimed to confirm the mediating effects of symptom experiences on the relationship between the body image and quality of life of hemodialysis patients. Data were collected from 153 patients who were diagnosed with ESRD at a tertiary general hospital and receiving regular hemodialysis in Korea. The data were collected between 20 July and 11 August 2023. The following statistical analyses were conducted: t-test, ANOVA, Scheffé test, Pearson's correlation coefficient analysis, and Hayes' Process Macro Model 4 (to test the mediating effect). The factors influencing quality of life were body image (β = 0.46, p < 0.001), monthly family income (over KRW 3 million) (β = 0.22, p = 0.002), and symptom experiences (β = -0.20, p = 0.001). The mediation analysis indicated that the symptom experiences mediated the relationship between body image and quality of life. Based on the results, education, counseling, and symptom management programs that can improve body image and reduce symptom experience should be developed, and customized programs that reflect the characteristics of a target population, such as economic level, should be developed and provided.

Digital Physical Activity and Exercise Interventions for People Living with Chronic Kidney Disease: A Systematic Review of Health Outcomes and Feasibility

Physical activity is essential to interrupt the cycle of deconditioning associated with chronic kidney disease (CKD). However, access to targeted physical activity interventions remain under-supported due to limited funding and specialised staff. Digital interventions may address some of these factors. This systematic review sought to examine the evidence base of digital interventions focused on promoting physical activity or exercise and their effect on health outcomes for people living with CKD. Electronic databases (PubMed, CINAHL, Embase, Cochrane) were searched from 1 January 2000 to 1 December 2023. Interventions (smartphone applications, activity trackers, websites) for adults with CKD (any stage, including transplant) which promoted physical activity or exercise were included. Study quality was assessed, and a narrative synthesis was conducted. Of the 4057 records identified, eight studies (five randomised controlled trials, three single-arm studies) were included, comprising 550 participants. Duration ranged from 12-weeks to 1-year. The findings indicated acceptability and feasibility were high, with small cohort numbers and high risk of bias. There were inconsistent measures of physical activity levels, self-efficacy, body composition, physical function, and psychological outcomes which resulted in no apparent effects of digital interventions on these domains. Data were insufficient for meta-analysis. The evidence for digital interventions to promote physical activity and exercise for people living with CKD is limited. Despite popularity, there is little evidence that current digital interventions yield the effects expected from traditional face-to-face interventions. However, 14 registered trials were identified which may strengthen the evidence-base.

Effectiveness of a mHealth platform-based lifestyle integrated multicomponent exercise (PF-Life) program to reverse pre-frailty in community-dwelling older adults: a randomized controlled trial study protocol

Background

Pre-frailty represents an ideal window of opportunity to potentially prevent frailty and disability. Early and effective interventions to delay or reverse pre-frailty are public health imperative. The present trial aims to evaluate the effectiveness and underlying mechanisms of mobile health (mHealth) platform-supported lifestyle-integrated multicomponent exercise (PF-Life) to reverse pre-frailty in community-dwelling older adults.

Methods

This is an open-label, prospective, two-arm parallel randomized controlled trial with allocation concealment and outcome assessment blinding. We aim to recruit 140 pre-frail community-dwelling older adults who will be randomized into two groups. The control group will receive a health education program, while the intervention group will receive PF-Life training as planned for 1 year. The proportion of pre-frailty, functional performance (muscular strength, aerobic capacity, flexibility, and balance), body composition, and physical activity will be measured at pre-intervention, post-intervention, and 12-month follow-up. Inflammatory biomarkers will also be collected to explore the underlying mechanisms.

Discussion

This is the first study to evaluate the effects of a novel digital lifestyle-integrated multicomponent exercise for pre-frail older people. The results of this trial will provide much-needed information on the short-and long-term effects of PF-Life based on functional performance and body composition. Meanwhile, inflammatory biomarkers and physical activity levels will be used to elucidate the underlying mechanisms of PF-Life. The findings from this trial will provide evidence for the effectiveness of lifestyle multicomponent exercise intervention supported by the mHealth platform that may reverse or even halt the onset of frailty.

Lifestyle interventions delivered by eHealth in chronic kidney disease: A scoping review

A method of overcoming barriers associated with implementing lifestyle interventions in CKD may be through the use of eHealth technologies. The aim of this review was to provide an up-to-date overview of the literature on this topic. Four bibliographical databases, two trial registers, and one database for conference proceedings were searched from inception to August 2023. Studies were eligible if they reported a lifestyle intervention using eHealth technologies. A narrative synthesis of the findings from the included studies structured around the type of eHealth intervention was presented. Where a sufficient number of studies overlapped in terms of the type of intervention and outcome measure these were brought together in a direction of effect plot. There were 54 included articles, of which 23 were randomised controlled trials (RCTs). The main component of the intervention for the included studies was mobile applications (n = 23), with the majority being in the dialysis population (n = 22). The majority of eHealth interventions were reported to be feasible and acceptable to participants. However, there was limited evidence that they were efficacious in improving clinical outcomes with the exception of blood pressure, intradialytic weight gain, potassium, and sodium. Although eHealth interventions appear acceptable and feasible to participants, there is insufficient evidence to make recommendations for specific interventions to be implemented into clinical care. Properly powered RCTs which not only demonstrate efficacy, but also address barriers to implementation are needed to enhance widespread adoption.

Development and Evaluation of a Mobile Application to Prevent Recurrent Stroke by Enhancing Self-management on Health Outcomes for Stroke Survivors

This study aimed to develop a Mobile Application to Prevent Recurrent Stroke to prevent recurrent stroke by enhancing self-management and to evaluate its effects on stroke survivors' health outcomes. The Mobile Application to Prevent Recurrent Stroke was developed based on social cognitive theory and the model in order of analysis, design, development, implementation, and evaluation process. The Mobile Application to Prevent Recurrent Stroke consisted of health management contents such as information about stroke, its associated risk factors, and required skills to conduct self-management with tailored support and counseling. A quasi-experimental preintervention and postintervention design was used involving a total of 54 stroke survivors. The experimental group (n = 27) was provided the Mobile Application to Prevent Recurrent Stroke for 8 weeks, whereas the control group (n = 27) received an education booklet. The result revealed that medication adherence ( P = .002), healthy eating habit ( P < .001), physical activity ( P < .001), and affected-side grip strength ( P = .002) in the experimental group were significantly better than those in the control group. The systolic blood pressure ( P = .020), diastolic blood pressure ( P < .001), body mass index ( P < .001), and waist circumference ( P < .001) in the experimental group were significantly lower than those in the control group. Stroke survivors can easily use this Mobile Application to Prevent Recurrent Stroke to improve self-management. Nurses can provide tailored care based on the lifelogging data of stroke survivors to prevent recurrent stroke.

Effects of an arteriovenous fistula stenosis prevention program in patients receiving hemodialysis

BACKGROUND

To increase the efficiency of hemodialysis, an appropriate vascular pathway must be created, and its function must be maintained. This study aimed to identify the effects of an arteriovenous fistula (AVF) stenosis prevention program on upper muscular strength, blood flow, physiological indexes, and self-efficacy among patients receiving hemodialysis.

METHODS

The participants were patients receiving hemodialysis at Keimyung University Dongsan Medical Center in Daegu, Republic of Korea. They were divided into experimental and control groups based on the day of the week they received hemodialysis at the outpatient department and included 25 participants each. The study was conducted for 8 weeks.

RESULTS

The AVF stenosis prevention program was effective in improving upper extremity muscle strength (F=15.23, p<0.001) and blood flow rate (F=36.00, p<0.001). As a result of the program, the phosphorus index level, which is a physiological indicator in hemodialysis patients, decreased (F=8.64, p<0.001). Encouragement and support through text messages and practice lists also resulted in an increase in self-efficacy (F=18.62, p<0.001).

CONCLUSION

The AVF stenosis prevention program in this study resulted in an increase in upper extremity muscle strength through grip strength exercises and was effective in preventing AVF stenosis by increasing the blood flow rate.

The effect of an educational app on hemodialysis patients' self-efficacy and self-care: A quasi-experimental longitudinal study

OBJECTIVE

Adequate self-care and exploring ways to improve it is imperative for patients with hemodialysis in order to meet the challenges arising from hemodialysis. This study aimed to determine the effect of an educational app on patients with hemodialysis' self-efficacy and self-care.

METHODS

The present study is a quasi-experimental longitudinal single-group study, carried out from October 2020 to March 2021 with the participation of 60 Patients with hemodialysis. Simple random sampling was used to sample patients. The intervention included an educational application, and participants completed questionnaires on self-efficacy and self-care performance at four points including baseline and at one, three, and six-month intervals post- intervention. Two-way ANOVA with repeated measures was used to examine the impact of the intervention. Bonferroni's posthoc test was also used for in-class calculation and comparison of changes over various periods.

RESULTS

The results of this study showed that the self-care performance of patients at different times was statistically significant (P <0.001). Also, the results showed that the mean total score of self-efficacy in the second period compared to the first was significantly improved (P <0.001). But the trend of changes in the third period compared to the second and the fourth to the third was not significant (p = 0.1 and p = .82). Also, a significant change was observed in the fourth period compared to the first (p = .029).

CONCLUSIONS

The study showed that education through a mobile app can result in significant improvements in these patients' self-care behaviors and self-efficacy over time. The educational intervention should be provided to patients with hemodialysis over a several-month period to allow for proper integration of the learning.

Mobile health platform based on user-centered design to promote exercise for patients with peripheral artery disease

BACKGROUND

Peripheral artery disease (PAD) is a cardiovascular disease that can be improved by risk factor modification. Mobile health (mHealth) intervention is an effective method of healthcare delivery to promote behavior changes. An mHealth platform can encourage consistent involvement of participants and healthcare providers for health promotion. This study aimed to develop an mHealth platform consisting of a smartphone application (app) synchronized with a wearable activity tracker and a web-based portal to support exercise intervention in patients with PAD.

METHODS

This study was conducted based on an iterative development process, including analysis, design, and implementation. In the analysis phase, a literature review and needs assessment through semi-structured interviews (n = 15) and a questionnaire-based survey (n = 138) were performed. The initial prototype design and contents were developed based on the users' requirements. In the implementation phase, multidisciplinary experts (n = 4) evaluated the heuristics, following which the mHealth platform was revised. User evaluation of the usability was performed by nurses (n = 4) and patients with PAD (n = 3).

RESULTS

Through the development process, the functional requirements of the platform were represented through visual display, reminder, education, self-monitoring, goal setting, goal attainment, feedback, and recording. In-app videos of exercise and PAD management were produced to provide information and in-app automatic text messages were developed for user motivation. The final version of the platform was rated 67.86 out of 100, which indicated "good" usability.

CONCLUSIONS

The mHealth platform was designed and developed for patients with PAD and their healthcare providers. This platform can be used to educate and promote individualized exercise among patients with PAD.

Effect of the SNS-Based Physical Activity-Related Psychological Intervention on Physical Activity and Psychological Constructs among Inactive University Students

Background/Objective

The current study investigated the effects of the physical activity-related psychological intervention via social network service (SNS) on physical activity and psychological constructs in inactive university students.

Method

Thirty inactive university students participated in the 12-week intervention and received the physical activity-related psychological strategy via SNS. The physical activity levels, stages of physical activity, self-efficacy, pros, and cons were measured at the three time points (baseline, after 6 weeks, and after 12 weeks). Data analyses included frequency analysis, McNemar chi-square (χ²) test, and a repeated measures ANOVA were conducted.

Results

Results indicated that the number of inactive university students gradually decreased across the three different time points, and that a total physical activity of inactive university students significantly increased over the 12-week intervention. In addition, pros and self-efficacy significantly increased but cons gradually decreased over the intervention.

Conclusions

The current study suggests that the SNS-based physical activity-related psychological strategies have positive effects on promoting physical activity and its related psychological constructs for inactive university students.

Self-Management Micro-Video Health Education Program for Hemodialysis Patients

Self-management in hemodialysis patients is critical; however, is generally low. This study aimed to examine the effects of a theory-based micro-video health education program on the improvement of self-management, hemodialysis knowledge, and self-efficacy in hemodialysis patients. A pre-test post-test control group quasi-experimental design was used to recruit 80 hemodialysis patients in a dialysis center. The participants were assigned in a 1:1 ratio to receive routine care or a 3-month micro-video health education program. Between-group comparison showed that patients in the intervention group had significantly greater improvement in hemodialysis knowledge than those in the control group (p < .05). However, no significant group differences were observed in terms of self-management and self-efficacy. Within-group comparison showed that the overall self-management level of patients in both groups improved significantly, particularly in problem-solving skills and self-care dimensions. Therefore, micro-video health education can improve the self-management and hemodialysis knowledge in Chinese patients undergoing hemodialysis.Trial Registration: Registered at ClinicalTrials.gov with study number (ChiCTR1800018172; http://www.chictr.org.cn/index.aspx).
