BACKGROUND: Public education has profound effects on the management effectiveness of invasive alien species by shaping stakeholders\' knowledge systems. However, our understanding of the association between social media and farmers\' knowledge is lacking for the majority of invasive agricultural pests. In this study, we used the fall armyworm (FAW), Spodoptera frugiperda, one of the most invasive insects globally, as a case to test the hypothesis that social media has a significant association with farmers\' knowledge of FAW. To address this, we developed a theoretical framework, conducted extensive household questionnaires in the China-Myanmar-Laos border region (China), and used quantitative descriptions and binary logistic regressions in statistical analyses.
RESULTS: Our results showed that (1) farmers frequently reported using 12 social media applications on smartphones (SMASs), and obtained FAW-relevant information from six of them, with high preferences for WeChat and TikTok, (2) farmers possessed a generally high level of knowledge of FAW which was significantly associated with their socio-demographic profiles, and (3) FAW-relevant information from SMASs was significantly associated with certain aspects of farmers\' knowledge of FAW.
CONCLUSIONS: We concluded that social media has a significant association with farmers\' knowledge of FAW. We suggest that well-designed and -conducted educational programs based on the use of SMASs could help improve the management of FAW, and the Department of Agricultural Extension could play an important and necessary role. Our findings provide insights into this novel educational approach for the management of serious invasive agricultural pests. © 2023 Society of Chemical Industry.

Human mobility restriction policies have been widely used to contain the coronavirus disease-19 (COVID-19). However, a critical question is how these policies affect individuals\' behavioral and psychological well-being during and after confinement periods. Here, we analyze China\'s five most stringent city-level lockdowns in 2021, treating them as natural experiments that allow for examining behavioral changes in millions of people through smartphone application use. We made three fundamental observations. First, the use of physical and economic activity-related apps experienced a steep decline, yet apps that provide daily necessities maintained normal usage. Second, apps that fulfilled lower-level human needs, such as working, socializing, information seeking, and entertainment, saw an immediate and substantial increase in screen time. Those that satisfied higher-level needs, such as education, only attracted delayed attention. Third, human behaviors demonstrated resilience as most routines resumed after the lockdowns were lifted. Nonetheless, long-term lifestyle changes were observed, as significant numbers of people chose to continue working and learning online, becoming \"digital residents.\" This study also demonstrates the capability of smartphone screen time analytics in the study of human behaviors.

Achieving glycemic control is a great challenge for young patients with type 1 diabetes (T1D), especially during the transition from childhood to adulthood. As various smartphone apps have been developed to improve glycemic control in T1D, we performed a meta-analysis of randomized controlled trials to assess the effect of smartphone apps on glycemic control in young patients with T1D.
We systematically searched PubMed, Embase, and the Cochrane Library for randomized controlled trials comparing combined usual care and smartphone app treatment to usual care alone. This meta-analysis is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. The primary outcomes were the weighted difference in means (WMD) of HbA1c change from baseline and the person-years incidence of mild hypoglycemia or severe hypoglycemia between intervention and control groups. We assessed pooled data by use of a random-effects model.
Of 1,190 identified studies, nine were eligible and included in our analysis (N = 748 participants). Relative to the control, using smartphone apps yielded a non-significant reduction in glycated hemoglobin (HbA1c) (WMD = -0.26, 95% CI: -0.56 to 0.05; p = 0.10) and no increased frequency of mild hypoglycemia (WMD = 1.87, 95% CI: -1.52 to 5.27; p = 0.49) or severe hypoglycemia (WMD = -0.04, 95% CI: -0.35 to 0.27; p = 0.80). In further subgroup analysis, compared with the recording-style app group, the auxiliary-style app group exhibited a significant reduction in HbA1c (WMD = -0.83, 95% CI: -1.10 to -0.56, p < 0.001).
The current pooled data analysis did not reveal a significant reduction in HbA1c in young patients with T1D undergoing treatment with smartphone apps and usual care in combination. However, auxiliary-style apps with insulin or carbo calculators were beneficial in reducing HbA1c.

UNASSIGNED: We started to design and test health education Apps for self-management among patients to provide a rich source of clinical support and information for patients to increase their ability of self-management.
UNASSIGNED: First, a multidisciplinary research team worked together to design and conduct the research. With their help, we redesigned an apps to incorporate some personalized changes for patients\' needs. Second, we chose a questionnaire from the Comprehensive Service Platform for the Elderly self-designed by CHENYu. Finally, a purposive sample of 34 users were tested experiences and satisfaction of users in Jul 2021.
UNASSIGNED: This research was successfully conducted in 22 wards among 23159 patients and 40440 chapters about healthy information sent to patients from Mar 2019 to January 2021 by smartphone. The data showed that 91.2% of participants resolved that the evaluation effect of the proposed application was better, in comparison with the paper version as routine verbal instruction. Additionally, 85.3% of participants wanted to continue to receive medical education information after discharge from the hospital. The top four most popular medical education information that they would like to receive included drug administration, disease prevention, nursing, and home care. Moreover, the top four most popular types of user suggestions were one-on-one online Q & A, continue to see every session, accelerate the speed of browsing and page updated, and free Wifi. The user satisfaction of the application was considerably high.
UNASSIGNED: The apps was welcomed by patients who wanted to increase their knowledge level of disease and perform self-management better.

UNASSIGNED: Zero-time Exercise (ZTEx), a simple strength- and stamina-enhancing physical activity (PA) requiring no extra equipment, can potentially increase PA and fitness. This pilot trial examined the feasibility and potential effectiveness of a smartphone ZTEx intervention to promote PA and fitness in patients with coronary heart disease (CHD).
UNASSIGNED: A parallel-group assessor-blinded pilot randomized controlled trial was conducted on Chinese patients with stable coronary heart disease (CHD) in three cardiology clinics. The experimental group received a 15-min brief individual face-to-face session and a 12-week ZTEx instant messaging with 28 picture e-messages and a smartphone ZTEx application (ZTExApp). The control group received the same duration of individual session and number and format of e-messages, but the content was healthy eating and breathing exercise. The feasibility was assessed based on: attrition rate, usage, response rate and perception of the intervention. The outcome evaluation included primary outcome (PA), fitness, exercise self-efficacy and intention, perceived happiness and health, and quality of life. A linear mixed model was used with intention-to-treat analysis adjusting for sex, age and baseline values. A semi-structured interview was conducted to collect feedback from the experiment group.
UNASSIGNED: One hundred thirty-nine patients (mean age 59.8 ± 6.6; 71.2% male) were randomized to the experimental group (n = 70) or control group (n = 69), and 80% (56/70) and 82% (57/69) of patients completed the 12-week follow-up assessment, respectively. The attrition rate was 18.7%. The experimental group reported that ZTEx was feasible to integrate PA into their daily life and appreciated the picture e-messages, and 95% of them sent feedback to us, but only 19.6% (13/70) of the participants entered their PA information into the e-diary of the ZTExApp. The experimental group had a significantly greater increase in time spent walking [mean difference (95% CI): 155.3 (10.1, 300.4), P = 0.04, Cohen\'s d = 0.34] than the control group.
UNASSIGNED: This pilot study showed using a brief ZTEx face-to-face session with picture e-messages empowered patients with CHD to integrate PA into daily life. Future definitive trials with a longer follow-up and a more user-friendly ZTExApp interface are necessary to determine the effectiveness of the smartphone ZTEx intervention in enhancing PA and related outcomes.
UNASSIGNED: The research protocol was registered at the Hong Kong University Clinical Trials Registry (HKUCTR) on 22 Jul 2016 (Study identifier: HKUCTR-2165) and was also retrospectively registered at the National Institutes of Health (identifier number: NCT03464331) on 14 March 2018.

China has had about 1.2 billion mobile-phone users, and this number continues to grow. However, mobile-health services (mHealth) are currently in the initial stage, and have not yet prevailed in China. Additionally, the prevalence of Parkinson\'s disease (PD) in China is 1700/100,000 (≥65 years). Indeed, these PD patients would benefit from mHealth to manage their disease. Therefore, we designed a study to determine attitudes toward smartphone applications (apps) for chronic condition self-management, and to discover the practicality of these apps among PD patients in China.
We selected 204 participants with PD between 52 and 87 years old and surveyed their attitudes concerning the use of smartphone apps for chronic condition management via questionnaires.
Among the participants, 65.19% had smartphones. Among these smartphone users, 82.84% expressed a preference for using apps for PD management. This group tended to be younger and more frequent web users with higher education and better medication compliance, and they tended to have a longer PD course and worse conditions (P < 0.001, P = 0.001, P < 0.001, P = 0.041, P < 0.001, P = 0.013). Additionally, the willingness to apply apps for PD self-management was positively related to education (P < 0.001) and negatively related to age and PD course (P = 0.017, P < 0.001).
In China, patients with PD have a generally positive attitude towards self-management through smartphone apps. Consequently, improving the coverage of smartphones with practical and handy apps is a promising strategy for PD self-management.

Physical activity (PA) smartphone applications (apps) featuring at least one behavioral change technique (BCT) are ubiquitous. Although BCTs in PA apps and their quality have been evaluated in Western countries, such research in China is new. This study (1) characterizes the extent that BCTs are implemented in Chinese PA apps and (2) evaluates their features and quality.
Of 5,253 PA apps identified in five Android app stores in China, 51 top-ranked PA apps with more than 2 million total downloads and user rating above 4 (out of 5) were selected and assessed; their BCTs were scored using the BCT taxonomy(V1), and app quality was evaluated with the Mobile App Rating Scale (MARS). Correlations among the number of BCTs, app quality, app features, app downloads, and user ratings were examined.
Of the top-ranked apps, 62.7% allow behavioral tracking (i.e., pedometer), 9.8% promote Chinese dancing, and 17.6% offer monetary incentives. The average number of BCT categories included in the apps analyzed was 11 (SD = 3.51; range = 3-16), with the most common ones comprising feedback and monitoring (88.2%), goals and planning (82.4%), social support (81.4%), and reward and threat (80.4%). The average scores for objective and subjective quality of these apps were 3.90 (SD = 0.44) and 2.27 (SD = 0.61), respectively, as assessed by MARS. Moderate positive correlations were observed among the number of BCT incorporated, apps quality, app features, and their total downloads.
Chinese PA apps vary in the number of BCTs incorporated, with goals setting, feedback, social support, and reward being typical. App objective quality is moderate, with relatively low subjective quality. Generally, higher quality PA apps in China include more BCTs with more app features and downloads. These findings can guide the development of PA apps to mitigate physical inactivity in China-and elsewhere.

BACKGROUND: With 360 million smokers, China consumes more cigarettes than any other country in the world. Given that 620 million Chinese own smartphones, smartphone apps for smoking cessation are increasingly used in China to help smokers quit.
OBJECTIVE: This study analyzed and evaluated the contents of all smoking cessation apps (iOS and Android) available in China, applying the China Clinical Smoking Cessation Guideline (CCSCG; identical to the US Clinical Practice Guideline for Treating Tobacco Use and Dependence) as a framework for analysis.
METHODS: We conducted a content analysis of Chinese Android and iOS smoking cessation apps (N=64) designed to assist users in quitting smoking. Each app was independently coded by two raters for its approach to smoking cessation and adherence to the CCSCG. We also recorded the features of smoking cessation apps (eg, release date, size, frequency of downloads, user ratings, type, quality scores by raters, and designers). Linear regression was used to test predictors of popularity and user-rated quality.
RESULTS: Chinese smoking cessation apps have low levels of adherence to guidelines, with an average score of 11.1 for Android and 14.6 for iOS apps on a scale of 0 to 46. There was no significant association between popularity, user rating, and the characteristics of apps. However, there was a positive relationship between popularity, user rating, and adherence score.
CONCLUSIONS: Chinese apps for smoking cessation have low levels of adherence to standard clinical practice guidelines. New apps need be developed and existing apps be revised following evidence-based principles in China.

Smartphone apps present a great opportunity for the management of cardiovascular disease (CVD) as the adoption of apps becomes increasingly popular in China. Yet, little is known about the status of CVD-related Smartphone apps in the country. The aim of this study was to examine the current status of CVD-related smartphone apps available for download in China.
Using CVD-related keywords written either in Chinese or English, the top 6 most popular smartphone app online stores in China were searched in September 2015. The information accountability of the selected apps was assessed with the Silberg scale. The key topic areas identified from the European Guidelines on cardiovascular disease prevention served to determine information coverage of the top 5 downloaded apps.
The average Silberg score of 151 apps was 2.87 (out of 9) with most apps not revealing authors\' qualifications and information references. There was also a lack of sponsorship disclosure and information update. Moreover, none of the top 5 downloaded apps covered all key areas of CVD management as recommended by the European Guidelines on cardiovascular disease prevention. There was little evidence of health professionals\' involvement in the formation of the CVD-related apps.
This study identified areas for improvement concerning information accountability and the scope of coverage of CVD-related apps downloadable in China. The findings may guide the future advancement of CVD-related apps and benefit CVD management in China.
