'It's a lonely journey': caregiving experiences and psychosocial distress among Chinese American dementia family caregivers

OBJECTIVES

Chinese American family caregivers of persons with Alzheimer's disease and related dementia (ADRD) are a vulnerable but understudied population. The goal of this qualitative study was to examine their caregiving experiences and psychosocial distress process and explore intervention strategies.

METHODS

In-depth individual interviews were conducted with 18 Chinese American dementia caregivers. All interviews were transcribed verbatim; thematic content analysis was conducted to construct a conceptual framework.

RESULTS

All participants reported high levels of caregiving stress associated with care-recipients' advanced symptoms and required assistance in activities in daily living. The relationship of caregiver and care-recipient was strained in their roles transition. The complex healthcare system, insurance policies, and a lack of linguistically appropriate services aggravated their psychosocial distress. Chinese cultural norms on 'family harmony' hindered their seeking of social support. Prolonged caregiving stress led to physical and mental impairment, including poor sleep, depression, and chronic conditions. Participants described their caregiving experience as 'a lonely journey' with a pervasive sense of hopelessness and withdrawal; their distress process was positively or negatively influenced by their coping strategies. All participants were eager for any kind of support; especially culturally appropriate programs that could improve their caregiving skills, self-care, and access to services.

CONCLUSION

Our data suggest that Chinese American dementia caregivers, especially those with limited English proficiency, experience elevated psychosocial distress, which was aggravated by the barriers to social support and health services due to their immigrant and minority status. Culturally appropriate targeted intervention is urgently needed for this underserved and vulnerable population.

Mobile health and behavior tracking (mHBT) among cancer survivors: results from a large and diverse sample

This study investigates the prevalence of mobile health and behavior tracking (mHBT) among a large and diverse sample of cancer survivors in the United States focusing on different mHBT adoption based on socio-demographic factors. Data was drawn from the 2020 to 2021 Health Information National Trends Survey (HINTS), which over-sampled cancer survivors from three cancer registries. Data analyses revealed that out of 1,234 cancer survivors studied, 39% had adopted mHBT, with 52% of these users engaging in daily tracking. A significant majority (86%) mHBT users were willing to share their data with healthcare providers. Notably, mHBT adoption was independently associated with younger age, female gender, college education, and better perceived health; but it was not significantly associated with race, income level, or state of residence after controlling for confounders. Cancer survivors' high rates of mHBT use and willingness to share data suggest the potential of using patient-generated data for personalized care and monitoring. However, caution is needed to address the digital divide and its impact on health disparities.

A WeChat-based Intervention, Wellness Enhancement for Caregivers (WECARE), for Chinese American Dementia Caregivers: Pilot Assessment of Feasibility, Acceptability, and Preliminary Efficacy

BACKGROUND

Chinese American family caregivers of persons with dementia experience high rates of psychosocial distress and adverse health outcomes. Due to their immigrant and minority status, they face substantial obstacles to care and support, including stigma and misperception of dementia, limited knowledge and use of welfare and services, and poor social support. Few interventions have been developed or tested for this vulnerable population.

OBJECTIVE

This study aims to pilot-test the Wellness Enhancement for Caregivers (WECARE) intervention, a culturally tailored program delivered via WeChat, a social media app highly popular in the Chinese population. The 7-week WECARE was designed specifically for Chinese American dementia caregivers to improve their caregiving skills, reduce stress, and enhance psychosocial well-being. Feasibility, acceptability, and preliminary efficacy of the WECARE were assessed in this pilot.

METHODS

A total of 24 Chinese American family caregivers of persons with dementia were recruited for a pre-post 1-arm trial of the WECARE. By subscribing to the WECARE official account, participants received interactive multimedia programs on their WeChat account multiple times a week for 7 weeks. A backend database automatically delivered program components and tracked user activities. Three online group meetings were organized to facilitate social networking. Participants completed a baseline and a follow-up survey. Feasibility was assessed by the follow-up rate and curriculum completion rate; acceptability was assessed by user satisfaction and perceived usefulness of the program; and efficacy was assessed with pre-post differences in 2 primary outcomes of depressive symptoms and caregiving burden.

RESULTS

The intervention was completed by 23 participants with a retention rate of 96%. Most of them (n=20, 83%) were older than 50 years and the majority (n=17, 71%) were female. The backend database revealed that the mean curriculum completion rate was 67%. Participants also reported high rates of user satisfaction and perceived usefulness of the intervention and high ratings of weekly programs. The intervention led to significant improvement in participants' psychosocial health outcomes; their depressive symptoms reduced from 5.74 to 3.35 with an effect size of -0.89 and caregiving burden decreased from 25.78 to 21.96 with an effect size of -0.48.

CONCLUSIONS

This pilot study suggests that WeChat-based WECARE intervention was feasible and acceptable; it also demonstrated initial efficacy in improving psychosocial well-being in Chinese American dementia caregivers. Further research with a control group is needed to assess its efficacy and effectiveness. The study highlights the need for more culturally appropriate mobile health interventions for Chinese American family caregivers of persons with dementia.

Social Determinants of COVID-19 Vaccination Rates: A Time-Constrained Multiple Mediation Analysis

Objective To estimate the multiple direct/indirect effects of social, environmental, and economic factors on COVID-19 vaccination rates (series complete) in the 3109 continental counties in the United States (U.S.). Study design  The dependent variable was the COVID-19 vaccination rates in the U.S. (April 15, 2022). Independent variables were collected from reliable secondary data sources, including the Census and CDC. Independent variables measured at two different time frames were utilized to predict vaccination rates. The number of vaccination sites in a given county was calculated using the geographic information system (GIS) packages as of April 9, 2022. The Internet Archive (Way Back Machine) was used to look up data for historical dates. Methods  A chain of temporally-constrained least absolute shrinkage and selection operator (LASSO) regressions was used to identify direct and indirect effects on vaccination rates. The first regression identified direct predictors of vaccination rates. Next, the direct predictors were set as response variables in subsequent regressions and regressed on variables that occurred before them. These regressions identified additional indirect predictors of vaccination. Finally, both direct and indirect variables were included in a network model. Results  Fifteen variables directly predicted vaccination rates and explained 43% of the variation in vaccination rates in April 2022. In addition, 11 variables indirectly affected vaccination rates, and their influence on vaccination was mediated by direct factors. For example, children in poverty rate mediated the effect of (a) median household income, (b) children in single-parent homes, and (c) income inequality. For another example, median household income mediated the effect of (a) the percentage of residents under the age of 18, (b) the percentage of residents who are Asian, (c) home ownership, and (d) traffic volume in the prior year. Our findings describe not only the direct but also the indirect effect of variables. Conclusions  A diverse set of demographics, social determinants, public health status, and provider characteristics predicted vaccination rates. Vaccination rates change systematically and are affected by the demographic composition and social determinants of illness within the county. One of the merits of our study is that it shows how the direct predictors of vaccination rates could be mediators of the effects of other variables.

Trends and differences in perceptions of patient-centered communication among adults in the US

OBJECTIVE

Patient-centered communication (PCC) is a key indicator of healthcare quality and is critical to patient-centered care. The purpose of this study is to examine the trends in PCC over the past decade and determine if differences in PCC by subpopulation remain METHODS: We used nationally representative survey data from the Health Information National Trends Study (HINTS) to examine PCC. We conducted trend and multivariate regression analyses to understand the changes of PCC scores and differences in PCC by key sociodemographic groups.

RESULTS

PCC reported among adults minimally increased with the largest increases in participants involved in making decisions regarding their healthcare. Participants who were non-Hispanic Black, older, had less than a high school education, or rural residents reported more positive perceptions of PCC CONCLUSION: Our findings indicate improvements to PCC over time. These findings also indicate that differences in patients' perceptions of PCC continue to persist and it's possible that personal expectations may influence a person's perception of the quality of PCC experienced PRACTICE IMPLICATIONS: This study highlights the continued need for provider education in patient emotional support and providing patients with the skills and resources to engage in high quality PCC.

A Social Media-Based Intervention for Chinese American Caregivers of Persons With Dementia: Protocol Development

BACKGROUND

Racial/ethnic minority and immigrant caregivers of persons with dementia experience high rates of psychosocial stress and adverse health outcomes. Few culturally tailored mobile health (mHealth) programs were designed for these vulnerable populations.

OBJECTIVE

This study reports the development of a culturally tailored mHealth program called Wellness Enhancement for Caregivers (WECARE) to improve caregiving skills, reduce distress, and improve the psychosocial well-being of Chinese American family caregivers of persons with dementia.

METHODS

Community-based user-centered design principles were applied in the program development. First, the structure and curriculum of the WECARE program were crafted based on existing evidence-based interventions for caregivers with input from 4 experts. Second, through working closely with 8 stakeholders, we culturally adapted evidence-based programs into multimedia program components. Lastly, 5 target users tested the initial WECARE program; their experience and feedback were used to further refine the program.

RESULTS

The resulting WECARE is a 7-week mHealth program delivered via WeChat, a social media app highly popular in Chinese Americans. By subscribing to the official WECARE account, users can receive 6 interactive multimedia articles pushed to their WeChat accounts each week for 7 weeks. The 7 major themes include (1) facts of dementia and caregiving; (2) the enhancement of caregiving skills; (3) effective communication with health care providers, care partners, and family members; (4) problem-solving skills for caregiving stress management; (5) stress reduction and depression prevention; (6) the practice of self-care and health behaviors; and (7) social support and available resources. Users also have the option of joining group chats for peer support. The WECARE program also includes a back-end database that manages intervention delivery and tracks user engagement.

CONCLUSIONS

The WECARE program represents one of the first culturally tailored social media-based interventions for Chinese American caregivers of persons with dementia. It demonstrates the use of community-based user-centered design principles in developing an mHealth intervention program in underserved communities. We call for more cultural adaptation and development of mHealth interventions for immigrant and racial/ethnic minority caregivers of persons with dementia.

Long-term effects of a social media-based intervention, Run4Love, on depressive symptoms of people living with HIV: Three-year follow-up of a randomized controlled trial (Preprint)

Background

Emerging studies have shown the effectiveness of mobile health (mHealth) interventions in reducing depressive symptoms among people living with HIV. Most of these studies included only short-term follow-up, with limited data on long-term effects.

Objective

The purpose of this study is to assess the long-term effects of a randomized controlled trial called Run4Love on depressive symptoms among people living with HIV at 1-year and 3-year follow-ups.

Methods

A total of 300 people living with HIV with depressive symptoms were recruited and randomized to an intervention or a control group in Guangzhou, China, from September 2017 to January 2018. The intervention group received a 3-month Run4Love program, including adapted evidence-based cognitive behavioral stress management courses and exercise promotion via WeChat (Tencent), a popular social media app. The control group received usual care and a brochure on nutrition. The primary outcome was reduction in depressive symptoms, measured using the Center for Epidemiological Studies–Depression (CES-D) scale. Data used in this study were collected at baseline and at the 1-year and 3-year follow-ups. Generalized estimating equations were used to examine the group differences at 1-year and 3-year follow-ups.

Results

Approximately half of the participants completed the assessment at 1-year (149/300, 49.7%) and 3-year (177/300, 59%) follow-ups. At 1-year follow-up, participants in the intervention group reported significant reduction in depressive symptoms compared with the control group (CES-D: from 23.9 to 18.1 in the intervention group vs from 24.3 to 23.3 in the control group; mean −4.79, SD 13.56; 95% CI −7.78 to −1.81; P=.002). At 3-year follow-up, between-group difference in CES-D remained statistically significant (from 23.9 to 20.5 in the intervention group vs from 24.3 to 24.4 in the control group; mean −3.63, SD 13.35; 95% CI −6.71 to −0.54; P=.02). No adverse events were reported during the 3-year follow-up period.

Conclusions

The mHealth intervention, Run4Love, significantly reduced depressive symptoms among people living with HIV, and the intervention effects were sustained at 1-year and 3-year follow-ups. Further research is needed to explore the mechanisms of the long-term effects of mHealth interventions such as Run4Love and to implement these effective interventions among people living with HIV.

Dose-Response Effects of Patient Engagement on Health Outcomes in an mHealth Intervention: Secondary Analysis of a Randomized Controlled Trial

Background

The dose–response relationship between patient engagement and long-term intervention effects in mobile health (mHealth) interventions are understudied. Studies exploring long-term and potentially changing relationships between patient engagement and health outcomes in mHealth interventions are needed.

Objective

This study aims to examine dose–response relationships between patient engagement and 3 psychosocial outcomes in an mHealth intervention, Run4Love, using repeated measurements of outcomes at baseline and 3, 6, and 9 months.

Methods

This study is a secondary analysis using longitudinal data from the Run4Love trial, a randomized controlled trial with 300 people living with HIV and elevated depressive symptoms to examine the effects of a 3-month mHealth intervention on reducing depressive symptoms and improving quality of life (QOL). We examined the relationships between patient engagement and depressive symptoms, QOL, and perceived stress in the intervention group (N=150) using 4–time-point outcome measurements. Patient engagement was assessed using the completion rate of course assignments and frequency of items completed. Cluster analysis was used to categorize patients into high- and low-engagement groups. Generalized linear mixed effects models were conducted to investigate the dose–response relationships between patient engagement and outcomes.

Results

The cluster analysis identified 2 clusters that were distinctively different from each other. The first cluster comprised 72 participants with good compliance to the intervention, completing an average of 74% (53/72) of intervention items (IQR 0.22). The second cluster comprised 78 participants with low compliance to the intervention, completing an average of 15% (11/72) of intervention items (IQR 0.23). Results of the generalized linear mixed effects models showed that, compared with the low-engagement group, the high-engagement group had a significant reduction in more depressive symptoms (β=−1.93; P=.008) and perceived stress (β=−1.72; P<.001) and an improved QOL (β=2.41; P=.01) over 9 months. From baseline to 3, 6, and 9 months, the differences in depressive symptoms between the 2 engagement groups were 0.8, 1.6, 2.3, and 3.7 points, respectively, indicating widening between-group differences over time. Similarly, between-group differences in QOL and perceived stress increased over time (group differences in QOL: 0.9, 1.9, 4.7, and 5.1 points, respectively; group differences in the Perceived Stress Scale: 0.9, 1.4, 2.3, and 3.0 points, respectively).

Conclusions

This study revealed a positive long-term dose–response relationship between patient engagement and 3 psychosocial outcomes among people living with HIV and elevated depressive symptoms in an mHealth intervention over 9 months using 4 time-point repeat measurement data. The high- and low-engagement groups showed significant and widening differences in depressive symptoms, QOL, and perceived stress at the 3-, 6-, and 9-month follow-ups. Future mHealth interventions should improve patient engagement to achieve long-term and sustained intervention effects.

Social media-based intervention to promote HBV screening and liver cancer prevention among Korean Americans: Results of a pilot study

Objective

In United States, Asian Americans are 10 times more likely to have hepatitis B virus (HBV) infection than Whites. Asian immigrants with limited English proficiency face extra barriers to HBV screening and many are unaware of the infectious status. This study aimed to evaluate a social media-based intervention to promote HBV screening and liver cancer prevention among Korean Americans (KA) with limited English proficiency.

Methods

Our community-academia partnership developed the “Lets talk about liver cancer” mHealth program by adapting a CDC media campaign. The program consisted of culturally tailored short video clips and pictorial messages and was delivered over 4 weeks to the participants via the popular Korean social media app, Kakao Talk. A total 100 KA living in greater Washington DC metropolitan were recruited via social media networks and completed this pre-post pilot study.

Results

Out of the 100 participants of KA, 56 were female, mean age was 60, and most have lived in the U.S. for more than 20 years, 84% had limited English proficiency, and 21% had a family history of HBV infection or liver cancer. After 4-week intervention, 95% completed the follow-up survey. Participants reported significant improvements in HBV-related knowledge, liver cancer prevention knowledge, perceived benefits of HBV testing, perceived risks of HBV infection, injunctive norms of HBV testing, and self-efficacy of HBV testing.

Conclusions

The Kakao Talk-based liver cancer prevention program for KAs was feasible and effective. We advocate for community-academia partnership to develop and implement culturally appropriate and social media-based interventions for underserved immigrants.

Clinical trial participation in America: The roles of eHealth engagement and patient-provider communication

Objective

Public participation in a clinical trial is the foundation of clinical research and the cornerstone for the discovery of new treatment and improving health outcomes. This study aims to examine how eHealth engagement, patient–provider communication, and clinical trial knowledge are associated with clinical trial participation in the United States.

Methods

Data were drawn from the Health Information National Trends Survey Iteration 5 Cycle 4 conducted in 2020. The sample included 3865 American adults aged 18 years and above. Path analysis using structural equation modeling and hierarchical linear regression was performed to examine the effects of eHealth engagement and patient–provider communication on clinical trial participation.

Results

About 5% of American adults have ever participated in a clinical trial. Younger adults, males, minorities, and people with lower education, less clinical trial knowledge, and less eHealth engagement were less likely to participate. After controlling for demographic variables, we found that more eHealth engagement led to a better knowledge of clinical trials, which was strongly associated with participation. Further, patient-centered communication did not directly lead to clinical trial participation; instead, it positively moderated the relationship between clinical trial knowledge and participation.

Conclusions

The national survey data indicate that American participation in clinical trials remains low and a significant disparity exists. Within the context of the eHealth movement, it is critical to implement targeted interventions to improve clinical trial knowledge, address the digital divide, and enhance patient-centered communication.

Mediating Effects of Stigma and Depressive Symptoms in a Social Media-Based Intervention to Improve Long-term Quality of Life Among People Living With HIV: Secondary Analysis of a Randomized Controlled Trial

BACKGROUND

Mobile health (mHealth) interventions have been shown to effectively improve the quality of life (QOL) among people living with HIV. However, little is known about the long-term effects of mHealth interventions.

OBJECTIVE

This study aims to explore the intervention mechanisms of a social media-based intervention, Run4Love, on the QOL of people with HIV over across a 9-month follow-up period.

METHODS

We recruited people living with HIV who were concurrently experiencing elevated depressive symptoms from an HIV outpatient clinic in South China. A total of 300 eligible participants were randomized either to the intervention group or the control group in a 1:1 ratio after they provided informed consent and completed a baseline survey. The intervention group received a 3-month WeChat-based intervention, comprising cognitive-behavioral stress management (CBSM) courses and physical activity promotion. The control group received a printed brochure on nutrition guidelines in addition to the usual care for HIV treatment. Neither participants nor the research staff were blinded to group assignment. All patients were followed at 3, 6, and 9 months. The primary outcome was depressive symptoms. Structural equation model (SEM) with longitudinal data was conducted to examine the sequential mediating effects of HIV-related stigma and depressive symptoms on the long-term intervention effects on participants' QOL.

RESULTS

About 91.3% (274/300), 88.3% (265/300), and 86.7% (260/300) of all participants completed follow-up surveys at 3, 6, and 9 months, respectively. Results showed that the intervention had significantly improved participants' QOL at 9 months, via complete mediating effects of reduced HIV-related stigma at 3 months and decreased depressive symptoms at 6 months. No adverse events were reported.

CONCLUSIONS

These findings underscore the critical roles of HIV-related stigma and depressive symptoms in an mHealth intervention with long-term effects on QOL improvements. We call for targeted mHealth interventions to improve QOL among people living with HIV, especially social media-based interventions that can address HIV-related stigma and alleviate depressive symptoms.

Patient-centered communication and emotional well-being in the era of medical violence in China

The past decade has witnessed an increasing number of patient assaults on doctors in China. Patient-centered communication (PCC) may be one way to mitigate this problem. This study examined the effects of PCC and patient trust on emotional health outcome, especially how patients' attitude toward medical violence affected this relationship. Data were drawn from the China Governance and Public Policy Survey administered in 2017 with a sample size of 3784. The results showed that PCC had no direct effect on emotional well-being. Instead, patient trust completely mediated this path. Also, patients' attitude toward medical violence increased the indirect effect of PCC on emotional well-being, suggesting a moderated mediation model. We call for education programs to promote PCC for both providers and patients, mass media campaigns to condemn violence against doctors and stricter law enforcement to stop medical violence.

Healthfulness Assessment of Recipes Shared on Pinterest: Natural Language Processing and Content Analysis

Background

Although Pinterest has become a popular platform for distributing influential information that shapes users’ behaviors, the role of recipes pinned on Pinterest in these behaviors is not well understood.

Objective

This study aims to explore the patterns of food ingredients and the nutritional content of recipes posted on Pinterest and to examine the factors associated with recipes that engage more users.

Methods

Data were collected from Pinterest between June 28 and July 12, 2020 (207 recipes and 2818 comments). All samples were collected via 2 new user accounts with no search history. A codebook was developed with a raw agreement rate of 0.97 across all variables. Content analysis and natural language processing sentiment analysis techniques were employed.

Results

Recipes using seafood or vegetables as the main ingredient had, on average, fewer calories and less sodium, sugar, and cholesterol than meat- or poultry-based recipes. For recipes using meat as the main ingredient, more than half of the energy was obtained from fat (277/490, 56.6%). Although the most followed pinners tended to post recipes containing more poultry or seafood and less meat, recipes with higher fat content or providing more calories per serving were more popular, having more shared photos or videos and comments. The natural language processing–based sentiment analysis suggested that Pinterest users weighted taste more heavily than complexity (225/2818, 8.0%) and health (84/2828, 2.9%).

Conclusions

Although popular pinners tended to post recipes with more seafood or poultry or vegetables and less meat, recipes with higher fat and sugar content were more user-engaging, with more photo or video shares and comments. Data on Pinterest behaviors can inform the development and implementation of nutrition health interventions to promote healthy recipe sharing on social media platforms.

Motivation to Participate in Precision Health Research and Acceptability of Texting as a Recruitment and Intervention Strategy Among Vietnamese Americans: Qualitative Study

Background

The largest effort undertaken in precision health research is the Precision Medicine Initiative (PMI), also known as the All of Us Research Program, which aims to include 1 million or more participants to be a part of a diverse database that can help revolutionize precision health research studies. Research participation from Asian Americans and Pacific Islanders in precision health research is, however, limited; this includes Vietnamese Americans, especially those with limited English proficiency. PMI engagement efforts with underserved communities, including members of minority populations or individuals who have experienced health disparities such as Vietnamese Americans with limited English proficiency, may help to enrich the diversity of the PMI.

Objective

The aim of this study is to examine the attitudes towards and perceptions of precision health, motivations and barriers to participation in precision health research, and acceptability of SMS text messaging as a recruitment and intervention strategy among underserved Vietnamese Americans.

Methods

A community sample of 37 Vietnamese Americans completed a survey and participated in one of 3 focus groups classified by age (18-30, 31-59, and ≥60 years) on topics related to precision health, participation in precision health research, texting or social media use experience, and insights on how to use text messages for recruitment and intervention. Participants were recruited via community organizations that serve Vietnamese Americans, flyers, word of mouth, and Vietnamese language radio announcements.

Results

Most participants had little knowledge of precision health initially. After brief education, they had positive attitudes toward precision health, although the motivation to participate in precision health research varied by age and prior experience of research participation. The main motivators to participate included the desire for more knowledge and more representation of Vietnamese Americans in research. Participants were open to receiving text messages as part of their research participation and provided specific suggestions on the design and delivery of such messages (eg, simple, in both English and Vietnamese). Examples of barriers included misinterpretation of messages, cost (to send text messages), and preferences for different texting platforms across age groups.

Conclusions

This study represents one of the first formative research studies to recruit underserved Vietnamese Americans to precision health research. It is critical to understand target communities’ motivations and barriers to participation in research. Delivering culturally appropriate text messages via age-appropriate texting and social media platforms may be an effective recruitment and intervention strategy. The next step is to develop and examine the feasibility of a culturally tailored precision health texting strategy for Vietnamese Americans.

Abstract PO-242: Viral hepatitis among foreign-born communities in the Washington- Baltimore metropolitan area: 5-year prevalence data and implications for linkage to care follow-up

Background: Viral hepatitis is a major public health problem around the world and in the United States, with significant morbidity and mortality. This research aimed to provide updated prevalence estimates and linkage-to-care rates for hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among foreign-born immigrants in the Washington-Baltimore metropolitan area. Methods: This retrospective cohort study analyzed screening data obtained from over 275 community-based outreach events held from 2015 to 2019. Through strategic collaborations and culturally-appropriate programs, the Hepatitis B Initiative of Washington DC was able to provide no-cost HBV and HCV testing, vaccination, and treatment linkage-to-care services to 9,489 and 9,427 individuals, respectively. We examined the prevalence of positive HBV (HBsAg+) and HCV (HCVAb+) infections and linkage-to-care with associated sociodemographic characteristics. Results: Overall, prevalence amongst foreign-born clients screened over the 5-year period was 4.3% for HBV and 1.1% for HCV. The highest HBV prevalence was among participants born in Malaysia (8.5%), Cambodia (7.7%), and Vietnam (6.9%), whereas HCV prevalence was highest among participants born in Mongolia (5.0%), Cameroon (3.2%), and Burma (1.5%). Among the 378 HBV- and 102 HCV-infected individuals who were referred to care, linkage- to-care rates were 87.0% (2016-2019) and 47.1% (2017-2019) respectively. Among those linked to care, an overwhelming proportion reported not having health insurance (74.8%) and/or a usual source of care (75.3%); the majority were also female (52.8%), over 30 years of age (96.6%), and born in Asia (78.0%). Conclusions: Foreign-born individuals from Asia and Africa had the highest prevalence of viral hepatitis. These results underscore the need to disaggregate screening data by country of birth to inform prevention and linkage-to-care programs and their impact. Additionally, optimal HBV and HCV screening and linkage-to-care can be achieved among harder-to-reach at-risk populations through partnerships with community organizations, health centers, and public health departments.

Relationship Between Patient Engagement and Depressive Symptoms Among People Living With HIV in a Mobile Health Intervention: Secondary Analysis of a Randomized Controlled Trial

BACKGROUND

Associations between higher levels of patient engagement and better health outcomes have been found in face-to-face interventions; studies on such associations with mobile health (mHealth) interventions have been limited and the results are inconclusive.

OBJECTIVE

The objective of this study is to investigate the relationship between patient engagement in an mHealth intervention and depressive symptoms using repeated measures of both patient engagement and patient outcomes at 4 time points.

METHODS

Data were drawn from a randomized controlled trial (RCT) of an mHealth intervention aimed at reducing depressive symptoms among people living with HIV and elevated depressive symptoms. We examined the association between patient engagement and depressive symptoms in the intervention group (n=150) where participants received an adapted cognitive-behavioral stress management (CBSM) course and physical activity promotion on their WeChat social media app. Depressive symptoms were repeatedly measured using the Patient Health Questionnaire (PHQ-9) at baseline and 1 month, 2 months, and 3 months. Patient engagement was correspondingly measured by the completion rate, frequency of items completed, and time spent on the program at 1 month, 2 months, and 3 months. Latent growth curve models (LGCMs) were used to explore the relationship between patient engagement and depressive symptoms at multiple time points in the intervention.

RESULTS

The mean PHQ-9 scores were 10.2 (SD 4.5), 7.7 (SD 4.8), 6.5 (SD 4.7), and 6.7 (SD 4.1) at baseline, 1 month, 2 months, and 3 months, respectively. The mean completion rates were 50.6% (SD 31.8%), 51.5% (SD 32.2%), and 50.8% (SD 33.7%) at 1, 2, and 3 months, respectively; the average frequencies of items completed were 18.0 (SD 14.6), 32.6 (SD 24.8), and 47.5 (SD 37.2) at 1, 2, and 3 months, respectively, and the mean times spent on the program were 32.7 (SD 66.7), 65.4 (SD 120.8), and 96.4 (SD 180.4) minutes at 1, 2, and 3 months, respectively. LGCMs showed good model fit and indicated that a higher completion rate (β at 3 months=-2.184, P=.048) and a greater frequency of items completed (β at 3 months=-0.018, P=.04) were associated with fewer depressive symptoms at 3 months. Although not significant, similar trends were found in the abovementioned relationships at 1 and 2 months. There was no significant relationship between time spent on the program and depressive symptoms.

CONCLUSIONS

This study revealed a positive association between patient engagement and health outcomes at 3 months of an mHealth intervention using LGCMs and repeated measures data. The results underscore the importance of improving patient engagement in mHealth interventions to improve patient-centered health outcomes.

Assessing Patient Experience and Healthcare Quality of Dental Care Using Patient Online Reviews in the United States: Mixed Methods Study

Background

Over the last two decades, patient review websites have emerged as an essential online platform for doctor ratings and reviews. Recent studies suggested the significance of such websites as a data source for patients to choose doctors for healthcare providers to learn and improve from patient feedback and to foster a culture of trust and transparency between patients and healthcare providers. However, as compared to other medical specialties, studies of online patient reviews that focus on dentists in the United States remain absent.

Objective

This study sought to understand to what extent online patient reviews can provide performance feedbacks that reflect dental care quality and patient experience.

Methods

Using mixed informatics methods incorporating statistics, natural language processing, and domain expert evaluation, we analyzed the online patient reviews of 204,751 dentists extracted from HealthGrades with two specific aims. First, we examined the associations between patient ratings and a variety of dentist characteristics. Second, we identified topics from patient reviews that can be mapped to the national assessment of dental patient experience measured by the Patient Experience Measures from the Consumer Assessment of Healthcare Providers and Systems (CAHPS) Dental Plan Survey.

Results

Higher ratings were associated with female dentists (t₇₁₈₈₁=2.45, P<.01, g=0.01), dentists at a younger age (F_{7, 107128}=246.97, P<.001, g=0.11), and those whose patients experienced a short wait time (F_{4, 150055}=10417.77, P<0.001, g=0.18). We also identified several topics that corresponded to CAHPS measures, including discomfort (eg, painful/painless root canal or deep cleaning), and ethics (eg, high-pressure sales, and unnecessary dental work).

Conclusions

These findings suggest that online patient reviews could be used as a data source for understanding the patient experience and healthcare quality in dentistry.

Trends and characteristics of protected health information breaches in the United States

OBJECTIVES

To evaluate the data breaches incidents in the U.S. between 2010 and 2018, identify the characteristics of breaches involving more than a million records, and compare the changes before and after wide adoption of EHR in 2015.

MATERIALS AND METHODS

Incidents of data breaches between 2010 to 2018 were retrieved from the Office of Civil Rights portal. Descriptive statistical analyses were performed to assess the trends and characteristics, and changes between states from 2015 to 2018 were assessed and mapped.

RESULTS

From 2010 to 2018, a total of 2,529 breaches affected 194.74 million individual records. Overall, 72.08% incidents involved healthcare providers; theft (32.94%) and hacking (22.7%) were major types of breaches. Large cases affecting more than a million records happened due to compromised internal structures and systems. After 2015, the magnitude of the data breaches has changed at varying levels in the U.S. states necessitating further research and actions.

Effect of a WeChat-Based Intervention (Run4Love) on Depressive Symptoms Among People Living With HIV in China: A Randomized Controlled Trial

BACKGROUND

People living with HIV (PLWH) have high rates of depressive symptoms. However, only a few effective mental health interventions exist for this vulnerable population.

OBJECTIVE

The aim of this study was to assess the efficacy of a WeChat-based intervention, Run4Love, with a randomized controlled trial among 300 people living with HIV and depression (PLWHD) in China.

METHODS

We recruited PLWH from the HIV outpatient clinic in South China. Participants were screened based on the Center for Epidemiologic Studies-Depression (CES-D) scale. Those who scored 16 or higher were eligible to participate. A total of 300 eligible patients were enrolled. After obtaining informed consent from the participants, completion of a baseline survey, and collection of participants' hair samples for measuring cortisol, the participants were randomly assigned to an intervention or a control group in a 1:1 ratio. The intervention group received the Run4Love program, delivered via the popular social media app WeChat. Cognitive behavioral stress management courses and weekly reminders of exercise were delivered in a multimedia format. Participants' progress was monitored with timely and tailored feedback. The control group received usual care and a brochure on nutrition for PLWH. Data were collected at 3, 6, and 9 months. The primary outcome was depression, which was measured by a validated instrument.

RESULTS

Participants in the intervention and control groups were comparable at baseline; about 91.3% (139/150), 88.3% (132/150), and 86.7% (130/150) participants completed the 3-, 6-, and 9-month follow-ups, respectively. At the 3-month follow-up, a significant reduction in CES-D score was observed in the intervention group (from 23.9 to 17.7 vs from 24.3 to 23.8; mean difference=-5.77, 95% CI -7.82 to -3.71; P<.001; standard effect size d=0.66). The mean changes in CES-D score from baseline to the 6- and 9-month follow-ups between the two groups remained statistically significant. No adverse events were reported.

CONCLUSIONS

The WeChat-based mobile health (mHealth) intervention Run4Love significantly reduced depressive symptoms among PLWHD, and the effect was sustained. An app-based mHealth intervention could provide a feasible therapeutic option for many PLWHD in resource-limited settings. Further research is needed to assess generalizability and cost-effectiveness of this intervention.

Use of Patient Portals of Electronic Health Records Remains Low From 2014 to 2018: Results From a National Survey and Policy Implications

PURPOSE

To investigate the trend of patient portal use in the general population and the barriers to adoption.

PARTICIPANTS

We analyzed 3 iterations of the Health Information National Trends Survey (HINTS) collected in 2014, 2017, and 2018.

MEASURES

Patient portal use, high-speed Internet access, data safety confidence, prior experience of online patient provider communication (OPPC), and demographic variables.

ANALYSIS

Logistic regression analyses were conducted separately for the 3 iterations of HINTS.

RESULTS

The use of patient portals increased from 25.6% in 2014 to 30.5% in 2017, and 31.4% in 2018. These users were more likely to be white female with higher levels of education or income. Meanwhile, high-speed Internet access, prior experience of OPPC, and data safety confidence were positive predictors of patient portal use in all 3 iterations.

CONCLUSION

The use of patient portals in the general public remains low and a significant digital divide persists, presenting a major challenge on meaningful use of electronic health record. We call for more effective interventions to address these gaps. Such interventions should target people of low socioeconomic status and focus on improving eHealth literacy and patients' confidence in data safety.

Academic Nurse-Managed Community Clinics Transitioning to Telehealth: Case Report on the Rapid Response to COVID-19

Background

In response to the COVID-19 pandemic, many health care organizations have adopted telehealth. The current literature on transitioning to telehealth has mostly been from large health care or specialty care organizations, with limited data from safety net or community clinics.

Objective

This is a case report on the rapid implementation of a telehealth hub at an academic nurse-managed community clinic in response to the national COVID-19 emergency. We also identify factors of success and challenges associated with the transition to telehealth.

Methods

This study was conducted at the George Mason University Mason and Partners clinic, which serves the dual mission of caring for community clinic patients and providing health professional education. We interviewed the leadership team of Mason and Partners clinics and summarized our findings.

Results

Mason and Partners clinics reacted quickly to the COVID-19 crisis and transitioned to telehealth within 2 weeks of the statewide lockdown. Protocols were developed for a coordination hub, a main patient triage and appointment telephone line, a step-by-step flowchart of clinical procedure, and a team structure with clearly defined work roles and backups. The clinics were able to maintain most of its clinical service and health education functions while adapting to new clinic duties that arose during the pandemic.

Conclusions

The experiences learned from the Mason and Partners clinics are transferable to other safety net clinics and academic nurse-led community clinics. The changes arising from the pandemic have resulted in sustainable procedures, and these changes will have a long-term impact on health care delivery and training.

A longitudinal analysis of the association between the living arrangements and psychological well-being of older Chinese adults: the role of income sources

Background

Understanding how living arrangements may affect psychological well-being (PWB) is critical in China, a society with the largest older population in the world. However, few studies have examined the moderating effect of income sources on the relationship between living arrangements and PWB. Our aim was to examine whether living arrangements are associated with PWB and whether income sources moderate this association.

Methods

The data were drawn from the third (2002) to sixth (2011/2012) waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Six questions reflecting older adults’ well-being were used to measure PWB. Living arrangements were classified as follows: living alone, living with family and living in an institution. Income sources were categorized into financially independent, supported by children, and governmental support. We performed random-effects ordinal probit models to examine the association of living arrangements with PWB and the moderating effect of income sources on this relationship.

Results

We included a total sample of 30,899 observations for 16,020 respondents aged 65 and over during 9-year follow-up. Older adults living with family (β = .29, p < .001) and those living in an institution (β = .34, p < .001) had stronger PWB than those living alone; moreover, support from children (β= −.24, p < .001) or from the government (β= −.08, p < .05) has a negative effect on PWB compared to the effect of financial self-support. Living in an institution with support from children (β= −.22, p < .05) led to lower PWB than living alone with financial self-support. The opposite result was observed for older adults living with their family and supported by the government (β = .16, p < .05).

Conclusions

Our analysis provides a significant contribution to the existing literature on the relationship between living arrangements and PWB in China. We recognize that living with family or in an institution leads to better PWB than does living alone. In addition, financial support from the government can moderate this association.

Assessment of eHealth behaviors in national surveys: a systematic review of instruments

Objectives

To conduct a systematic review of instruments used in national surveys of eHealth behaviors.

Materials and Methods

Major databases and websites of federal agencies were searched with pre-determined inclusion and exclusion criteria. National surveys with measures of eHealth behaviors were identified. The survey instruments were retrieved, and their measures of eHealth behaviors were categorized and critiqued.

Results

We located 13 national surveys containing eHealth behavior assessment questions that were administered from 1999 to 2017. Most surveys were conducted annually or biennially and typically covered topics on searching health information, obtaining social support, communicating with healthcare providers, and buying medicine online; recent surveys included items related to personal health management and use of mobile tools. There were redundant measures of searching health information online but insufficient measures of use of mobile apps, social media, and wearable devices.

Discussion

Future assessment of eHealth behaviors should reflect the growing varieties of behaviors enabled by technology development and reflect the current mobile ownership patterns in diverse social groups. More studies also need to include longitudinal surveys, integrative and standardized measures, and better designs to allow data linkage and comparison.

Conclusion

The existing survey instruments covering eHealth behaviors are rather limited compared to fast technological progress. We call for more national surveys on eHealth behaviors that are more responsive to technology development; we also advocate for more analysis and dissemination of existing national data on eHealth behaviors for evidence-based health policies.

Mechanisms and Effects of a WeChat-Based Intervention on Suicide Among People Living With HIV and Depression: Path Model Analysis of a Randomized Controlled Trial

Background

People living with HIV and depression have high rates of suicide. Studies of mobile health (mHealth) interventions have shown feasibility, acceptability, and efficacy in improving mental health in people living with HIV and depression. However, few studies have examined the mechanisms and effects of mHealth interventions on suicide.

Objective

This study was designed to examine the mechanisms and effects of a WeChat-based intervention, Run4Love, on suicide among people living with HIV and depression in China, while considering perceived stress and depressive symptoms as mediators.

Methods

A sample of 300 People living with HIV and depression was recruited from the outpatient clinic of a large HIV or AIDS treatment hospital and was randomized to the Run4Love group or a control group. Data were collected at baseline, 3-, 6-, and 9-month follow-ups. Path analysis modeling, with longitudinal data, was used in data analyses.

Results

The Run4Love mHealth intervention had a direct effect on reducing suicide rate at the 6-month follow-up (beta=−.18, P=.02) and indirect effect through reducing perceived stress and depressive symptoms at the 3-month follow-up (beta=−.09, P=.001). A partial mediating effect between perceived stress and depressive symptoms accounted for 33% (–0.09/–0.27) of the total effect.

Conclusions

Through path analyses, we understood the mechanisms and effects of an mHealth intervention on suicide prevention. The findings underscored the importance of stress reduction and depression treatment in such a program. We call for more effective suicide prevention, especially mHealth interventions targeting the vulnerable population of people living with HIV and depression.

Gender differences in the relationship of sexual partnership characteristics and inconsistent condom use among people living with HIV in China

Few studies have examined the relationship between inconsistent condom use and sexual partnership characteristics among people living with HIV (PLWH). The current study focused on such association and its gender differences. The study was conducted in a large hospital in South China in 2013. A total of 320 dyads (PLWH indexes and their sexual partners) were recruited from an outpatient clinic using convenience sampling. The proportion of inconsistent condom use in the last six months among female indexes was higher than that among male indexes (52.4% vs. 43.6%). Of sexual partnership characteristics, HIV seropositive status was a risk factor for inconsistent condom use for both male and female indexes (aOR = 2.32, 95%CI = 1.15∼4.66, aOR = 3.09, 95%CI = 1.10∼8.67, respectively). For male indexes, lower educational level was also a risk factor (aOR = 2.39, 95%CI = 1.23∼4.67); while having had emotionally intimate relationships was a protective factor (aOR = 0.40, 95%CI = 0.21∼0.77). For female indexes, receiving material support was a risk factor (aOR = 10.17, 95%CI = 2.13∼48.61) and receiving health-related advice was a protective factor (aOR = 0.11, 95%CI = 0.02∼0.55). Future HIV interventions for PLWH need to be gender-sensitive and include their sexual partners.

What Do Patients Say About Doctors Online? A Systematic Review of Studies on Patient Online Reviews

Background

The number of patient online reviews (PORs) has grown significantly, and PORs have played an increasingly important role in patients’ choice of health care providers.

Objective

The objective of our study was to systematically review studies on PORs, summarize the major findings and study characteristics, identify literature gaps, and make recommendations for future research.

Methods

A major database search was completed in January 2019. Studies were included if they (1) focused on PORs of physicians and hospitals, (2) reported qualitative or quantitative results from analysis of PORs, and (3) peer-reviewed empirical studies. Study characteristics and major findings were synthesized using predesigned tables.

Results

A total of 63 studies (69 articles) that met the above criteria were included in the review. Most studies (n=48) were conducted in the United States, including Puerto Rico, and the remaining were from Europe, Australia, and China. Earlier studies (published before 2010) used content analysis with small sample sizes; more recent studies retrieved and analyzed larger datasets using machine learning technologies. The number of PORs ranged from fewer than 200 to over 700,000. About 90% of the studies were focused on clinicians, typically specialists such as surgeons; 27% covered health care organizations, typically hospitals; and some studied both. A majority of PORs were positive and patients’ comments on their providers were favorable. Although most studies were descriptive, some compared PORs with traditional surveys of patient experience and found a high degree of correlation and some compared PORs with clinical outcomes but found a low level of correlation.

Conclusions

PORs contain valuable information that can generate insights into quality of care and patient-provider relationship, but it has not been systematically used for studies of health care quality. With the advancement of machine learning and data analysis tools, we anticipate more research on PORs based on testable hypotheses and rigorous analytic methods.

Differential effects of unemployment on depression in people living with HIV/AIDS: a quantile regression approach

Unemployment is associated with depression in people living with HIV (PLWH). However, few studies have examined the effects of unemployment on PLWH with different levels of depression. The current study explores the plausible differential effects of unemployment on the different percentiles of depression in PLWH employing a quantile regression (QR) approach, based on a recent survey of 411 PLWH in China. Among participants, 47.7% had elevated depressive symptoms, and 23.8% were unemployed. The effects of unemployment on depression were statistically significant with a trend of initial increase followed by a decline at the quantile levels of 0.51-0.90 of depression. The maximum effect of unemployment status on depression was statistically significant at the 70th and 75th percentiles of depression (coefficient = 7.0, p < .01). Tailored strategies and interventions should be implemented to address the differential needs of PLWH with various levels of depressive symptoms.

Effects of the Chronic Disease Self-Management Program on medication adherence among older adults

Despite many interventions to promote medication adherence in older adults, we know little about how medication adherence has improved as a result of such interventions. The purpose of this study was to examine the long-term program impacts on medication adherence from participating in the Chronic Disease Self-Management Program (CDSMP). Secondary data used for this study included the CDSMP participants' sociodemographic characteristics and their baseline and 6- and 12-month follow-up assessments on health-related indicators, including medication adherence, self-rated health, depression, and patient communication skills. This study included those who were 65 years or older, had one or more chronic conditions, and attended at least the first or second session. Linear mixed models were used to analyze the impacts of short-term (6 months) changes in health-related indicators on long-term (12 months) changes in medication nonadherence. The subset analyses were performed among participants with self-rated major depression at baseline. This study included 687 participants. Self-reported medication adherence did not improve significantly at 6-month follow-up assessment but significantly improved at 12-month follow-up assessment. Among those with self-reported major depression at baseline assessment, the short-term improvements in depression and self-rated health were associated with long-term changes in medication adherence. The long-term impacts of the CDSMP on medication adherence were influenced by the short-term program impacts on health-related indicators. More targeted interventions are needed for patients with major depression, and programs such as the CDSMP can be particularly helpful among the population.

Attitudes, Beliefs, and Cost-Related Medication Nonadherence Among Adults Aged 65 or Older With Chronic Diseases

INTRODUCTION

Cost-related medication nonadherence (CRN) can negatively affect chronic disease prevention and management in an aging population. Limited data are available on the interacting influences among such factors as availability of financial resources, attitudes and beliefs of patients, and CRN. The objective of this study was to examine the causal paths among financial resource availability, patient attitudes and beliefs, and CRN.

METHODS

We used a nationally representative sample (n = 4,818) from the 2015 National Health Interview Survey; selected respondents were aged 65 or older, had a diagnosis of hypertension or diabetes or both, and were prescribed medication for at least 1 of these conditions. We performed structural equation modeling to examine whether perceived medication affordability, access to health care, and patient satisfaction influenced the effects of financial resource availability on CRN (skipped doses, took less medicine, or delayed filling a prescription to save money).

RESULTS

Six percent of respondents reported CRN in the previous 12 months. The model showed a good to fair fit, and all paths were significant (P < .05) except for age. The effects of financial resource availability on CRN was mediated through perceived medication affordability, access to health care, and patient satisfaction with health care services.

CONCLUSION

This study suggests that patients' attitudes and beliefs can mediate the effects of financial resource availability on CRN. We call for senior-friendly public health interventions that can address these modifiable barriers to reduce CRN among older adults with chronic conditions.

A Profile of eHealth Behaviors in China: Results From a National Survey Show a Low of Usage and Significant Digital Divide

Background: The widely accessible Internet has boosted an enthusiasm for eHealth in China, but we know little about eHealth behaviors in the general population.

Objective: To assess the prevalence of eHealth behaviors in general Chinese population and identify the predictors of digital divide.

Methods: A nationally representative survey was administered in 2016–2017 with a sample size of 4,043. Five eHealth behaviors were assessed: search health information, communicate with healthcare providers, connect with patients of similar health conditions, buy medicine, and make doctor's appointment online. Multivariate logistic regression was employed to assess the independent relationship between eHealth behaviors and key demographic variables.

Results: About 33% of participants have ever searched health information online, and the prevalence of other eHealth behaviors was less than 10%. The adoption of eHealth behaviors was significantly associated with younger age, more education, higher income, and urban residence. By contrast, gender, employment status, health insurance, and health status were not associated with eHealth behavior.

Conclusion: The adoption of eHealth behaviors in the general Chinese population was low, and a significant digital divide exists. We caution against the speedy development of Internet hospitals and call for more resources allocated to bridge digital health divide.

Development and Feasibility Testing of an mHealth (Text Message and WeChat) Intervention to Improve the Medication Adherence and Quality of Life of People Living with HIV in China: Pilot Randomized Controlled Trial

Background

Most people living with HIV (PLWH) reside in middle- and low-income countries with limited access to health services. Thus, cost-effective interventions that can reach a large number of PLWH are urgently needed.

Objective

The objective of our study was to assess the feasibility and acceptability of an mHealth intervention among PLWH in China.

Methods

Based on previous formative research, we designed an mHealth intervention program that included sending weekly reminders to participants via text messages (short message service, SMS) and articles on HIV self-management three times a week via a popular social media app WeChat. A total of 62 PLWH recruited from an HIV outpatient clinic were randomly assigned to intervention or control group. The intervention lasted for 3 months, and all participants were assessed for their medication adherence, presence of depression, quality of life (QoL), and CD4 (cluster of differentiation 4) counts. Upon completing the intervention, we interviewed 31 participants to further assess the feasibility and acceptability of the study.

Results

At baseline, the intervention and control groups did not differ in terms of demographic characteristics or any of the major outcome measures. About 85% (53/62) of the participants completed the intervention, and they provided valuable feedback on the design and content of the intervention. Participants preferred WeChat as the platform for receiving information and interactive communication for ease of access. Furthermore, they made specific recommendations about building trust, interactive features, and personalized feedback. In the follow-up assessment, the intervention and control groups did not differ in terms of major outcome measures.

Conclusions

This pilot study represents one of the first efforts to develop a text messaging (SMS)- and WeChat-based intervention that focused on improving the medication adherence and QoL of PLWH in China. Our data indicates that an mHealth intervention is feasible and acceptable to this population. The data collected through this pilot study will inform the future designs and implementations of mHealth interventions in this vulnerable population. We recommend more innovative mHealth interventions with rigorous designs for the PLWH in middle- and low-income countries.

Run4Love, a mHealth (WeChat-based) intervention to improve mental health of people living with HIV: a randomized controlled trial protocol

BACKGROUND

People living with HIV (PLWH) suffer from high rates of mental illness; but targeted effective interventions are limited, especially in developing countries. High penetration of smartphone usage and widespread acceptance of social media applications provide an unprecedented opportunity for mobile-based health interventions (mHealth interventions) in resource-limited settings like China. The current report describes the design and sample characteristics of the Run4Love randomized controlled trial (RCT) aimed at improving mental health in PLWH in China.

METHODS

A total of 300 PLWH with elevated depressive symptoms were recruited and randomized into either the intervention or control group. Participants in the intervention group received an adapted cognitive-behavioral stress management (CBSM) course delivered by the enhanced WeChat platform (for 3 months) and were motivated to engage in physical activities. Progress of the participants was automatically tracked and monitored with timely feedback and rewards. The control group received a brochure on nutrition for PLWH in addition to standard care. The outcome assessments are conducted at baseline, 3, 6, and 9 months using tablets. The primary outcome is depressive symptoms measured by the scale of the Center for Epidemiology Studies Depression (CES-D). Secondary outcomes include quality of life, chronic stress measured with biomarker of hair cortisol, and other measures of stress and depression, self-efficacy, coping, HIV-related stigma, physical activity, and patient satisfaction. Mixed effects model with repeated measures (MMRM) will be used to analyze the intervention effects.

DISCUSSION

The Run4Love study is among the first efforts to develop and evaluate a multicomponent and integrated mHealth intervention to improve the mental health and quality of life of PLWH. Once proven effective, Run4Love could be scaled up and potentially integrated into the routine case management of PLWH and adapted to other populations with chronic diseases.

Association between exercise and the risk of dementia: results from a nationwide longitudinal study in China

OBJECTIVE

This study was conducted to examine the causal association between exercise and the risk of dementia among older Chinese adults.

DESIGN

Longitudinal population-based study with a follow-up duration of 9 years.

SETTING

Data for the Chinese Longitudinal Healthy Longevity Survey waves occurring from 2002 to 2011-2012 were extracted from the survey database.

PARTICIPANTS

In total, 7501 dementia-free subjects who were older than 65 years were included at baseline. Dementia was defined as a self-reported or proxy-reported physician's diagnosis of the disease.

OUTCOME MEASURES AND METHODS

Regular exercise and potential confounding variables were obtained via a self-report questionnaire. We generated longitudinal logistic regression models based on time-lagged generalised estimating equation to examine the causal association between exercise and dementia risk.

RESULTS

Of the 7501 older Chinese people included in this study, 338 developed dementia during the 9-year follow-up period after excluding those who were lost to follow-up or deceased. People who regularly exercised had lower odds of developing dementia (OR=0.53, 95% CI 0.33 to 0.85) than those who did not exercise regularly.

CONCLUSION

Regular exercise was associated with decreased risk of dementia. Policy-makers should develop effective public health programmes and build exercise-friendly environments for the general public.

A Multi-Level, Mobile-Enabled Intervention to Promote Physical Activity in Older Adults in the Primary Care Setting (iCanFit 2.0): Protocol for a Cluster Randomized Controlled Trial

BACKGROUND

Most older adults do not adhere to the US Centers for Disease Control physical activity guidelines; their physical inactivity contributes to overweight and multiple chronic conditions. An urgent need exists for effective physical activity-promotion programs for the large number of older adults in the United States.

OBJECTIVE

This study presents the development of the intervention and trial protocol of iCanFit 2.0, a multi-level, mobile-enabled, physical activity-promotion program developed for overweight older adults in primary care settings.

METHODS

The iCanFit 2.0 program was developed based on our prior mHealth intervention programs, qualitative interviews with older patients in a primary care clinic, and iterative discussions with key stakeholders. We will test the efficacy of iCanFit 2.0 through a cluster randomized controlled trial in six pairs of primary care clinics.

RESULTS

The proposed protocol received a high score in a National Institutes of Health review, but was not funded due to limited funding sources. We are seeking other funding sources to conduct the project.

CONCLUSIONS

The iCanFit 2.0 program is one of the first multi-level, mobile-enabled, physical activity-promotion programs for older adults in a primary care setting. The development process has actively involved older patients and other key stakeholders. The patients, primary care providers, health coaches, and family and friends were engaged in the program using a low-cost, off-the-shelf mobile tool. Such low-cost, multi-level programs can potentially address the high prevalence of physical inactivity in older adults.

The Digital Divide and Health Disparities in China: Evidence From a National Survey and Policy Implications

Background

The digital divide persists despite broad accessibility of mobile tools. The relationship between the digital divide and health disparities reflects social status in terms of access to resources and health outcomes; however, data on this relationship are limited from developing countries such as China.

Objective

The aim of this study was to examine the current rates of access to mobile tools (Internet use and mobile phone ownership) among older Chinese individuals (aged ≥45 years), the predictors of access at individual and community levels, and the relationship between access to mobile tools and health outcomes.

Methods

We drew cross-sectional data from a national representative survey, the China Health and Retirement Longitudinal Study (CHARLS), which focused on the older population (aged ≥45 years). We used two-level mixed logistic regression models, controlling for unobserved heterogeneity at the community and individual levels for data analysis. In addition to individual-level socioeconomic status (SES), we included community-level resources such as neighborhood amenities, health care facilities, and community organizations. Health outcomes were measured by self-reported health and absence of disability based on validated scales.

Results

Among the 18,215 participants, 6.51% had used the Internet in the past month, and 83% owned a mobile phone. In the multivariate models, Internet use was strongly associated with SES, rural or urban residence, neighborhood amenities, community resources, and geographic region. Mobile phone ownership was strongly associated with SES and rural/urban residence but not so much with neighborhood amenities and community resources. Internet use was a significant predictor of self-reported health status, and mobile phone ownership was significantly associated with having disability even after controlling for potential confounders at the individual and community levels.

Conclusions

This study is one of the first to examine digital divide and its relationship with health disparities in China. The data showed a significant digital divide in China, especially in the older population. Internet access is still limited to people with higher SES; however, the mobile phone has been adopted by the general population. The digital divide is associated with not only individual SES but also community resources. Future electronic health (eHealth) programs need to consider the accessibility of mobile tools and develop culturally appropriate programs for various social groups.

Has the Digital Health Divide Widened? Trends of Health-Related Internet Use Among Older Adults From 2003 to 2011

Objectives

To examine the trend of health-related Internet use (HRIU) among older adults.

Methods

We analyzed data from the 2003, 2005, and 2011-2012 iterations of the National Cancer Institute (NCI)-sponsored Health Information National Trends Survey (HINTS). HRIU was measured by 4 online behaviors: seeking health information, buying medicine, connecting with people with similar health problems, and communicating with doctors.

Results

Internet use and HRIU among older adults increased substantially from 2003 to 2011 with more significant increases in seeking health information and communicating with doctors online. Overall, the digital health divide between different demographic groups has narrowed, especially in terms of gender, racial/ethnic group, rural/urban residence, and various health statuses; however, age, education, and household income remain persistent predictors of the digital divide. Those in the oldest group (75 or older), those with less than a high school education, and those with very low income (<$25,000/year) continuously lagged behind their counterparts in all aspects of HRIU.

Conclusions

Despite an overall increase in HRIU and a narrowed digital divide, significant variations in HRIU in different demographic groups persisted; therefore, we call for more senior-friendly online resources and culturally appropriate interventions to bridge the digital health divide for vulnerable older adults.

Digital Divide and Health Disparities in China: Data from a National Longitudinal Survey of CHARLS

The China Health and Retirement Longitudinal Study (CHARLS, 2013) data was used to investigate internet use and mobile phone ownership in older Chinese adults and examine digital divide and social economic status and mobile technology adoption and health outcomes associations. Results suggest a significant digital divide associated with not only individual characteristics, but also neighborhood resources. Future eHealth programs should consider the accessibility of mobile tools and develop culturally appropriate programs for different social groups.

Clinical impact of coexisting retinopathy and vascular calcification on chronic kidney disease progression and cardiovascular events

BACKGROUND AND AIMS

Retinopathy and vascular calcification (VC) are representative markers of microvascular and macrovascular dysfunction in patients with chronic kidney disease (CKD). However, their relationship and combined effects on clinical outcomes remain undetermined.

METHODS AND RESULTS

We included 523 patients with nondialysis-dependent CKD stage 3-5 who had been examined with fundus photography for diabetic or hypertensive retinopathy. Simple radiographs were analyzed for the presence of VC. The clinical significance of VC of the abdominal aorta and iliofemoral artery (apVC) and retinopathy was evaluated in terms of the rate of renal function decline and composite of any cardiovascular event or death. CKD patients with retinopathy showed higher prevalence of apVC than those without retinopathy (25.6% vs. 12.5%, P < 0.001).The presence of retinopathy was independently associated with apVC (OR 2.13, 95% CI 1.31, 3.49). In multivariate analysis, compared with subjects with neither apVC nor retinopathy, the coexistence of both apVC and retinopathy were independently associated with rapid renal function decline (β = -1.51; 95% CI -2.40, -0.61), whereas apVC or retinopathy alone were not. Compared with subjects with neither apVC nor retinopathy, the HRs for composite end points were 1.05 (95% CI 0.48, 2.27), 1.79 (95% CI 1.14, 2.80), and 2.07 (95% CI 1.17, 3.67) for patients with apVC only, those with retinopathy only, and those with both apVC and retinopathy, respectively.

CONCLUSION

The coexistence of VC and retinopathy was independently associated with CKD progression and cardiovascular events or deaths, and its combined effect was stronger than any separate condition.

Apps seeking theories: results of a study on the use of health behavior change theories in cancer survivorship mobile apps

Background

Thousands of mobile health apps are now available for use on mobile phones for a variety of uses and conditions, including cancer survivorship. Many of these apps appear to deliver health behavior interventions but may fail to consider design considerations based in human computer interface and health behavior change theories.

Objective

This study is designed to assess the presence of and manner in which health behavior change and health communication theories are applied in mobile phone cancer survivorship apps.

Methods

The research team selected a set of criteria-based health apps for mobile phones and assessed each app using qualitative coding methods to assess the application of health behavior change and communication theories. Each app was assessed using a coding derived from the taxonomy of 26 health behavior change techniques by Abraham and Michie with a few important changes based on the characteristics of mHealth apps that are specific to information processing and human computer interaction such as control theory and feedback systems.

Results

A total of 68 mobile phone apps and games built on the iOS and Android platforms were coded, with 65 being unique. Using a Cohen’s kappa analysis statistic, the inter-rater reliability for the iOS apps was 86.1 (P<.001) and for the Android apps, 77.4 (P<.001). For the most part, the scores for inclusion of theory-based health behavior change characteristics in the iOS platform cancer survivorship apps were consistently higher than those of the Android platform apps. For personalization and tailoring, 67% of the iOS apps (24/36) had these elements as compared to 38% of the Android apps (12/32). In the area of prompting for intention formation, 67% of the iOS apps (34/36) indicated these elements as compared to 16% (5/32) of the Android apps.

Conclusions

Mobile apps are rapidly emerging as a way to deliver health behavior change interventions that can be tailored or personalized for individuals. As these apps and games continue to evolve and include interactive and adaptive sensors and other forms of dynamic feedback, their content and interventional elements need to be grounded in human computer interface design and health behavior and communication theory and practice.

Decreased parathyroid Klotho expression is associated with persistent hyperparathyroidism after kidney transplantation

Although successful kidney transplantation usually corrects hyperparathyroidism, the condition persists in some patients. The present study was designed to determine whether Klotho or fibroblast growth factor 23, the key regulator of parathyroid hormone, is involved in persistent hyperparathyroidism in kidney transplant recipients (KTRs). Nineteen hyperplastic parathyroid glands were obtained from end-stage renal disease (ESRD) patients and KTRs; 6 normal parathyroid glands were used as controls. We compared the expression of Klotho, fibroblast growth factor receptor 1 (FGFR1) and calcium-sensing receptor (CaSR) in the KTRs and ESRD patients. Expressions of Klotho, FGFR1, CaSR and vitamin D receptor, as evaluated by immunohistochemistry, were quantified as the number of positive cells per unit area. The Klotho, FGFR1 and CaSR expressions in parathyroid glands of the post-kidney transplantation (PSKT) and the ESRD groups were significantly decreased compared with normal controls. In the ESRD group, Klotho expression and number of proliferating cell nuclear antigen-positive cells in the parathyroid gland were significantly decreased in parathyroid adenomas as compared with parathyroid hyperplasia. The expression of FGFR1 and CaSR in the parathyroid glands was significantly increased in the PSKT compared with the ESRD group. There was no significant difference in Klotho expression between the PSKT and ESRD groups. Incomplete recovery of Klotho levels in the parathyroid gland may play a role in the pathogenesis of tertiary hyperparathyroidism after kidney transplantation.

Resveratrol prevents renal lipotoxicity and inhibits mesangial cell glucotoxicity in a manner dependent on the AMPK-SIRT1-PGC1α axis in db/db mice

AIMS/HYPOTHESIS

Many of the effects of resveratrol are consistent with the activation of AMP-activated protein kinase (AMPK), silent information regulator T1 (SIRT1) and peroxisome proliferator-activated receptor (PPAR)γ co-activator 1α (PGC-1α), which play key roles in the regulation of lipid and glucose homeostasis, and in the control of oxidative stress. We investigated whether resveratrol has protective effects on the kidney in type 2 diabetes.

METHODS

Four groups of male C57BLKS/J db/m and db/db mice were used in this study. Resveratrol was administered via gavage to diabetic and non-diabetic mice, starting at 8 weeks of age, for 12 weeks.

RESULTS

The db/db mice treated with resveratrol had decreased albuminuria. Resveratrol ameliorated glomerular matrix expansion and inflammation. Resveratrol also lowered the NEFA and triacylglycerol content of the kidney, and this action was related to increases in the phosphorylation of AMPK and the activation of SIRT1-PGC-1α signalling and of the key downstream effectors, the PPARα-oestrogen-related receptor (ERR)-1α-sterol regulatory element-binding protein 1 (SREBP1). Furthermore, resveratrol decreased the activity of phosphatidylinositol-3 kinase (PI3K)-Akt phosphorylation and class O forkhead box (FOXO)3a phosphorylation, which resulted in a decrease in B cell leukaemia/lymphoma 2 (BCL-2)-associated X protein (BAX) and increases in BCL-2, superoxide dismutase (SOD)1 and SOD2 production. Consequently, resveratrol reversed the increase in renal apoptotic cells and oxidative stress, as reflected by renal 8-hydroxy-deoxyguanosine (8-OH-dG), urinary 8-OH-dG and isoprostane concentrations. Resveratrol prevented high-glucose-induced oxidative stress and apoptosis in cultured mesangial cells through the phosphorylation of AMPK and activation of SIRT1-PGC-1α signalling and the downstream effectors, PPARα-ERR-1α-SREBP1.

CONCLUSIONS/INTERPRETATION

The results suggest that resveratrol prevents diabetic nephropathy in db/db mice by the phosphorylation of AMPK and activation of SIRT1-PGC-1α signalling, which appear to prevent lipotoxicity-related apoptosis and oxidative stress in the kidney.

Clinical usefulness of 3-dimensional computerized tomographic renal angiography to detect transplant renal artery stenosis

OBJECTIVE

The aim of this study was to evaluate whether 3-dimensional computerized tomographic angiography (3D-CTA) is useful to detect transplant renal artery stenosis (TRAS).

METHODS

Fourteen patients with clinically suspected TRAS underwent color Doppler ultrasonography (CDU) and 3D-CTA before renal angiography. We compared 3D-CTA and CDU for accuracy based on the results of renal angiography. The safety of 3D-CTA was investigated by measuring the estimated glomerular filtration rate (eGFR) before and after the 3D-CTA examination.

RESULTS

The 10 men and 4 women who participated in this study showed a mean eGFR of 75 mL/min/1.73 m(2) (range 60-94). Of these, 9 patients were diagnosed with TRAS. 3D-CTA detected stenoses in all 9 patients, but CDU failed to detect it in 3, including, 2 with end-to-side arterial anastomoses, which may be more challenging to detect compared with end-to-end anastomoses. The stenotic area in 3D-CTA was similar to that detected by renal angiography (70 ± 12 vs 68 ± 11). The eGFR did not differ significantly before versus after the 3D-CTA examination; 72 ± 13 vs 69 ± 14 mL/min/1.73 m(2).

CONCLUSIONS

3D-CTA was an effective safe method to detect renal artery stenosis among transplant recipients with an eGFR >60 mL/min/1.73 m(2).
