Combined use of a healthy lifestyle smartphone application and usual primary care counseling to improve arterial stiffness, blood pressure and wave reflections: a Randomized Controlled Trial (EVIDENT II Study)

Effectiveness of digital health interventions for telemedicine/telehealth for managing blood pressure in adults: a systematic review and meta-analysis

This systematic review and meta-analysis included randomized controlled trials or observational studies that compare digital health interventions (DHIs) for telemedicine/telehealth versus usual care for managing blood pressure (BP) in adults. We searched PubMed, Cochrane CENTRAL, and IchuShi-Web, and used a random-effects meta-analysis of the weighted mean difference (MD) between the comparison groups to pool data from the included studies. The outcome included the pooled MD of office BP from baseline to each follow-up period. This meta-analysis considered 117 studies with 68677 participants as eligible. The 3-month intervention period reduced office systolic BP (SBP) compared with usual care in 38 studies (MD: -3.21 mmHg [95% confidence interval: -4.51 to -1.90]), with evidence of heterogeneity. Office SBP across intervention periods demonstrated comparable effects (3-, 6- [54 studies], 12- [43 studies], and >12-month periods [9 studies]). The benefits for office diastolic BP were similar to those for office SBP. Additionally, the interventions significantly reduced the office SBP compared with the control, regardless of the mode of intervention delivery (smartphone apps [38 studies], text messages [35 studies], and websites [34 studies]) or type of facility (medical [74 studies] vs. non-medical [33 studies]). The interventions were more effective in 41 hypertension cohorts compared with 66 non-hypertension cohorts (-4.81 mmHg [-6.33, -3.29] vs. -2.17 mmHg [-3.15, -1.19], P = 0.006 for heterogeneity). In conclusion, DHIs for telemedicine/telehealth improved BP management compared with usual care. The effectiveness with heterogeneity should be considered, as prudent for implementing evidence-based medicine. This meta-analysis considered 117 studies with 68677 participants eligible. The DHIs for telemedicine/telehealth reduced office BP compared with usual care, regardless of intervention duration, intervention delivery mode, facility type, and cohort type. Additionally, the DHIs reduced the risk of uncontrolled BP compared with usual care, regardless of intervention duration, intervention delivery mode, and facility type.

Long-Term Effectiveness of a Smartphone App and a Smart Band on Arterial Stiffness and Central Hemodynamic Parameters in a Population with Overweight and Obesity (Evident 3 Study): Randomised Controlled Trial

BACKGROUND

mHealth technologies could help to improve cardiovascular health; however, their effect on arterial stiffness and hemodynamic parameters has not been explored to date.

OBJECTIVE

To evaluate the effect of a mHealth intervention, at 3 and 12 months, on arterial stiffness and central hemodynamic parameters in a sedentary population with overweight and obesity.

METHODS

Randomised controlled clinical trial (Evident 3 study). 253 subjects were included: 127 in the intervention group (IG) and 126 in the control group (CG). The IG subjects were briefed on the use of the Evident 3 app and a smart band (Mi Band 2, Xiaomi) for 3 months to promote healthy lifestyles. All measurements were recorded in the baseline visit and at 3 and 12 months. The carotid-femoral pulse wave velocity (cfPWV) and the central hemodynamic parameters were measured using a SphigmoCor System^® device, whereas the brachial-ankle pulse wave velocity (baPWV) and the Cardio Ankle Vascular Index (CAVI) were measured using a VaSera VS-2000^® device.

RESULTS

Of the 253 subjects who attended the initial visit, 237 (93.7%) completed the visit at 3 months of the intervention, and 217 (85.3%) completed the visit at 12 months of the intervention. At 12 months, IG showed a decrease in peripheral augmentation index (PAIx) (-3.60; 95% CI -7.22 to -0.00) and ejection duration (ED) (-0.82; 95% CI -1.36 to -0.27), and an increase in subendocardial viability ratio (SEVR) (5.31; 95% CI 1.18 to 9.44). In CG, cfPWV decreased at 3 months (-0.28 m/s; 95% CI -0.54 to -0.02) and at 12 months (-0.30 m/s, 95% CI -0.54 to -0.05), central diastolic pressure (cDBP) decreased at 12 months (-1.64 mm/Hg; 95% CI -3.19 to -0.10). When comparing the groups we found no differences between any variables analyzed.

CONCLUSIONS

In sedentary adults with overweight or obesity, the multicomponent intervention (Smartphone app and an activity-tracking band) for 3 months did not modify arterial stiffness or the central hemodynamic parameters, with respect to the control group. However, at 12 months, CG presented a decrease of cfPWV and cDBP, whereas IG showed a decrease of PAIx and ED and an increase of SEVR.

The Effectiveness of a Mobile Health Care App and Human Coaching Program in Primary Care Clinics: Pilot Multicenter Real-World Study

Background

As the global burden of chronic conditions increases, their effective management is a concern. Although the need for chronic disease management using mobile self-management health care apps is increasing, there are still many barriers to their practical application in the primary care field.

Objective

This study evaluated the effectiveness of primary care services combining a mobile self-management health care app with human coaching for patients with chronic diseases in the current primary care system.

Methods

A total of 110 patients (mean age 53.2, SD 9.2 years; 64 of 110, 58.2% female) with hypertension, diabetes, dyslipidemia, or metabolic syndrome who visited one of 17 participating primary care clinics from September to November 2020 were included in this study. All participants recorded data regarding changes in body weight, sleep conditions, quality of life, depression, anxiety, stress, BMI, waist circumference, blood sugar levels, blood pressure, and blood lipids levels. The app user group (n=65) used a mobile self-management health care app with human coaching for 12 weeks, and the control group (n=45) underwent conventional self-managed health care.

Results

Patients in the app user group reported significantly more weight loss than those in the control group—the body weight of the app user group decreased by 1.43 kg (95% CI –2.07 to –0.79) and that of the control group decreased by 0.13 kg (95% CI –0.67 to 0.41; P=.002). The weight loss was markedly greater after using the app for 9 weeks than that when used for 4 weeks or 5-8 weeks (P=.002). Patients in the app user group reported better sleep quality (P=.04) and duration (P=.004) than those in the control group.

Conclusions

The combination of primary care clinics and a mobile self-management health care app with human coaching results in better management of chronic conditions. This study shows that the primary care services combining a mobile self-management health care app with human coaching are effective in the current primary care system. An implication of this study is the possibility that a mobile self-management health care app with human coaching is a treatment option in the current primary care system.

Mobile health strategies for blood pressure self-management in urban populations with digital barriers: systematic review and meta-analyses

Mobile health (mHealth) technologies improve hypertension outcomes, but it is unknown if this benefit applies to all populations. This review aimed to describe the impact of mHealth interventions on blood pressure outcomes in populations with disparities in digital health use. We conducted a systematic search to identify studies with systolic blood pressure (SBP) outcomes located in urban settings in high-income countries that included a digital health disparity population, defined as mean age ≥65 years; lower educational attainment (≥60% ≤high school education); and/or racial/ethnic minority (<50% non-Hispanic White for US studies). Interventions were categorized using an established self-management taxonomy. We conducted a narrative synthesis; among randomized clinical trials (RCTs) with a six-month SBP outcome, we conducted random-effects meta-analyses. Twenty-nine articles (representing 25 studies) were included, of which 15 were RCTs. Fifteen studies used text messaging; twelve used mobile applications. Studies were included based on race/ethnicity (14), education (10), and/or age (6). Common intervention components were: lifestyle advice (20); provision of self-monitoring equipment (17); and training on digital device use (15). In the meta-analyses of seven RCTs, SBP reduction at 6-months in the intervention group (mean SBP difference = -4.10, 95% CI: [-6.38, -1.83]) was significant, but there was no significant difference in SBP change between the intervention and control groups (p = 0.48). The use of mHealth tools has shown promise for chronic disease management but few studies have included older, limited educational attainment, or minority populations. Additional robust studies with these populations are needed to determine what interventions work best for diverse hypertensive patients.

Nutrition and physical activity interventions for the general population with and without cardiometabolic risk: a scoping review

OBJECTIVE

The objective of this scoping review was to examine the research question: In the adults with or without cardiometabolic risk, what is the availability of literature examining interventions to improve or maintain nutrition and physical activity-related outcomes? Sub-topics included: (1) behaviour counseling or coaching from a dietitian/nutritionist or exercise practitioner, (2) mobile applications to improve nutrition and physical activity and (3) nutritional ergogenic aids.

DESIGN

The current study is a scoping review. A literature search of the Medline Complete, CINAHL Complete, Cochrane Database of Systematic Reviews and other databases was conducted to identify articles published in the English language from January 2005 until May 2020. Data were synthesised using bubble charts and heat maps.

SETTING

Out-patient, community and workplace.

PARTICIPANTS

Adults with or without cardiometabolic risk factors living in economically developed countries.

RESULTS

Searches resulted in 19 474 unique articles and 170 articles were included in this scoping review, including one guideline, thirty systematic reviews (SR), 134 randomised controlled trials and five non-randomised trials. Mobile applications (n 37) as well as ergogenic aids (n 87) have been addressed in several recent studies, including SR. While primary research has examined the effect of individual-level nutrition and physical activity counseling or coaching from a dietitian/nutritionist and/or exercise practitioner (n 48), interventions provided by these practitioners have not been recently synthesised in SR.

CONCLUSION

SR of behaviour counseling or coaching provided by a dietitian/nutritionist and/or exercise practitioner are needed and can inform practice for practitioners working with individuals who are healthy or have cardiometabolic risk.

Perspectives of patients and physicians regarding hypertensive management from an online survey for excellence: a subanalysis of the PARADOX study by physician categories

An existing clinical problem in Japan is the high prevalence of uncontrolled hypertension despite the availability of various effective therapies. Here, we analyzed survey data to gain insight into this paradox from physicians’ perspectives, with results categorized according to specialty (i.e., with or without certification by the Japanese Society of Hypertension [JSH]), institution type, gender, and age. A web-based survey of typical educational activities for patients regarding hypertension management was conducted in Japan between October 19 and 31, 2017. Differences between physician groups were investigated per category. Survey results from 541 physicians were analyzed: 59 JSH certified (i.e., ‘specialist’) vs 482 non-JSH certified (i.e., ‘nonspecialist’) physicians; 192 general practitioners vs 349 hospital physicians; 500 males vs 41 females; and 178 younger (mean age: 40.7 years), 174 middle-aged (52.0 years) or 189 older (61.3 years) physicians. The most statistically significant differences between groups were observed in the category of physician specialty. Compared with nonspecialists, specialist physicians were more conscious of providing education on patient lifestyle modifications, more aware of patient- and physician-derived issues, and understood and followed the treatment guidelines. General practitioners cared more about the patient’s burden than did hospital physicians. Younger physicians identified the need to incorporate the patient’s perspective into their treatment. This analysis shows that the provision and perceptions of education differ between physician categories. Compared with specialist physicians, nonspecialists were less likely to provide adequate guidance on lifestyle modifications, possibly due to their uncertainty in understanding treatment guideline recommendations. Further education of nonspecialists on hypertension management may be warranted.

Physician and patient perspectives on hypertension management and factors associated with lifestyle modifications in Japan: results from an online survey

We conducted a survey to examine the gaps between Japanese physician and patient perspectives on hypertension management and to investigate important factors that may help solve the “hypertension paradox” in Japan. Web-based surveys of patients and physicians were conducted in Japan between October 19 and 31, 2017. The data collected included physician and patient perspectives on hypertension education, adherence to lifestyle modifications and antihypertensive medication, and reasons for treatment adherence/nonadherence. Factors relating to specific patient behaviors (e.g., monitoring their home blood pressure [BP] daily) were analyzed by multivariate logistic regression analysis. Of the 541 physicians and 881 patients included in the analyses, both groups recognized that the extent of lifestyle changes was insufficient. Approximately 80% of physicians reported that they fully or sufficiently provided education to patients about reasons for hypertension treatment and its associated risks, target BP levels, and lifestyle modifications. Only 40–50% of patients considered those topics having been fully or sufficiently discussed. Logistic regression analyses revealed that positive lifestyle modifications (daily home BP monitoring, salt intake <6 g/day, and daily aerobic exercise for ≥30 min) were positively associated with receiving feedback from physicians about specific lifestyle modifications and patient motivation for maintaining their target BP. In conclusion, perception of the amount of education provided by physicians on hypertension management was lower in patients than in physicians. In addition to effective regular follow-up regarding lifestyle modifications, patient motivation by physicians is an important factor for improving lifestyle modifications and achieving effective hypertension management in Japan.

Association between ideal cardiovascular health score trajectories and arterial stiffness: the Kailuan Study

Some studies have shown that a higher ideal cardiovascular health score (CVHS) predicts a lower incidence of arterial stiffness. Few studies have used multiple measurements of CVHS to examine the impact of CVHS on arterial stiffness. The current study aimed to identify the long-term patterns in CVHS trajectory and to explore the association between CVHS trajectory and arterial stiffness. The study cohort consisted of 18,854 participants from the Kailuan Study who were followed up for five physical examinations over 8.10 years. Five discrete CVHS trajectories were identified among the participants: low-stable (8.10%), low-moderate (6.84%), moderate-low (23.46%), moderate-stable (39.83%), and elevated-stable (21.77%). After adjustment for confounding factors, generalized linear model analysis showed that CVHS trajectory group correlated negatively with brachial-ankle pulse wave velocity (baPWV). Compared with the low-stable group, the low-moderate group, moderate-low group, moderate-stable group, and elevated-stable group had B values of -41.81, -24.11, -86.79, and -169.54, respectively. We also used logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for CVHS trajectory groups and arterial stiffness. In fully adjusted models, ORs were 0.76 (95% CI: 0.62-0.94) for the low-moderate group, 0.80 (95% CI: 0.67-0.97) for the moderate-low group, 0.51 (95% CI: 0.42-0.62) for the moderate-stable group, and 0.23 (95% CI: 0.18-0.29) for the elevated-stable group compared with the low-stable group. The results were consistent across a number of sensitivity analyses. In conclusion, the higher long-term attainment and the improvement of CVHS were negatively associated with baPWV and could reduce the risk of arterial stiffness. Our study emphasizes the importance of optimizing CVH throughout life to prevent the incidence of arterial stiffness.
