Introduction: Digital device helps children enhance academic, cognitive and psychomotor skills. However, prolonged use causes physical inactivity, poor interpersonal skills and communication problems. Information on digital device use among young children in Malaysia is currently limited. Hence, this study aimed to determine the prevalence of digital device utilisation among preschool children in Kota Setar District, Kedah. Methods: A cross-sectional study at government preschools in Kota Setar District was conducted from February to April 2020. Selection of preschools and students was done using multistage simple randomisation. A self-administered questionnaire containing demographic and digital device use details was filled by parents. Results: The prevalence of digital device use among preschool children was 95.9% and mostly used smartphones (94.2%). Most children (95%) did not own the device, and usage was under supervision (95.7%). The reason for supervision was to prevent exposure to inappropriate content (70.5%). The common reasons for allowing digital device use were for educational (37.4%) and entertainment purposes (36%) through videos (30.9%) and games (30.2%). Approximately 21.5% and 50.3% of the children spent more than 1 and 2 hours on digital devices during weekdays and weekends, respectively. Conclusion The prevalence of digital device use among the preschool children in Kota Setar District was very high. Most of them used digital devices for educational and entertainment purposes under parental supervision. However, some exceeded the recommended screen time on weekends. These findings could promote awareness of digital device use among young children and help design public health awareness programmes and future policies.

BACKGROUND: To combat coronavirus disease 2019 (COVID-19), many countries have used contact tracing apps, including Japan's voluntary-use contact-confirming application (COCOA). The current study aimed to identify industry and workplace characteristics associated with the downloading of this COVID-19 contact tracing app. METHODS: This cross-sectional study of full-time workers used an online survey. Multiple logistic regression analysis was used to evaluate the associations of industry and workplace characteristics with contact tracing app use. RESULTS: Of the 27,036 participants, 25.1% had downloaded the COCOA. Workers in the public service (adjusted odds ratio [aOR] = 1.29, 95% confidence interval [CI] 1.14-1.45) and information technology (aOR = 1.38, 95% CI 1.20-1.58) industries were more likely to use the app than were those in the manufacturing industry. In contrast, app usage was less common among workers in the retail and wholesale (aOR = 0.87, 95% CI 0.76-0.99) and food/beverage (aOR = 0.81, 95% CI 0.70-0.94) industries, but further adjustment for company size attenuated these associations. Workers at larger companies were more likely to use the app. Compared with permanent employees, the odds of using the app were higher for managers and civil servants but lower for those who were self-employed. CONCLUSIONS Downloading of COCOA among Japanese workers was insufficient; thus, the mitigating effect of COCOA on the COVID-19 pandemic is considered to be limited. One possible reason for the under-implementation of the contact tracing app in the retail and wholesale and food/beverage industries is small company size, as suggested by the fully adjusted model results. An awareness campaign should be conducted to promote the widespread use of the contact tracing app in these industries.

PURPOSE: This study aimed to develop a smartphone overdependence prevention program for college students based on the self-determination theory (SDT) and evaluate its effectiveness.METHODS: A non-equivalent control group repeated measures design was used for the study. Participants were 64 university freshmen (experimental group: 29, control group: 35). The developed program consists of eight sessions conducted twice a week. The program was designed to promote autonomy, competence, and relatedness the three elements of the basic psychological needs of self-determination theory. The participants were assessed before the program, immediately after, and 1 and 3 months after the program. Data were collected from April 23 to September 14, 2018 and analyzed by performing a Chi-square test, Fisher's exact test, independent t-test, and repeated measures ANOVA using SPSS/WIN 23.0.RESULTS: This study showed improvement in the basic psychological needs (F=3.90, p =.010) in the experimental group compared to the control group. Specifically, competence (F=2.93, p =.035), relatedness (F=2.89, p =.045), and self-regulatory ability (F=3.11, p =.028) improved significantly.CONCLUSION: Study findings indicate thatthe smartphone overdependence prevention program based on the Self-determination theory could be an effective intervention for improving basic psychological needs and self-regulation ability. Therefore, this program could be an efficient strategy for smartphone overdependence prevention in university students.

PURPOSE: To examine the effects of a smartphone application-based exercise program on self-efficacy expectations (SEE) and outcome expectations regarding exercise (OEE), physical fitness, activity level, physiological indices, and health-related quality of life in a sample of hemodialysis patients.METHODS: A quasi-experimental control group pre-test post-test design was used. Subjects were recruited from two university hospitals in G city. The subjects were assigned randomly by coin toss: 33 participants to the experimental group and 30 to the control group. A literature review and the self-efficacy theory were used to develop the smartphone program. Experts designed and verified the program to be userfriendly and in consideration of user interaction. Data were collected through a self-report pre-test post-test questionnaire and online medical records.RESULTS: In the experimental group, the levels of physical fitness and physical activity were significantly improved post-test, but the scores on health-related quality of life and the physical indices did not improve. In the experimental group, the SEE and OEE post-test scores were also significantly higher than the pre-test scores, but the control group's scores did not change.CONCLUSION: The smartphone application-based exercise program based on self-efficacy theory significantly improved the level of physical fitness and activity, SEE, and OEE for hemodialysis patients. The use of this application-based exercise program for hemodialysis patients might be an effective nursing intervention tool for improving SEE, OEE, level of physical fitness, and physical activity.

BACKGROUND: Behavior guidance is a technique used to subdue inappropriate behavior by establishing communication that meets the needs of a child. This study aimed to measure the effectiveness of a mobile app (Little Lovely Dentist) compared to the tell-show-do (TSD) technique in managing anxious children during their first dental visit.METHODS: Fifty children (30 boys and 20 girls) without any past dental experience, aged from 7 to 11 years, were randomly allocated into either the dental app group or the TSD group. The pre- and post-operative anxiety of children who underwent prophylactic cleaning was assessed both physiologically and subjectively using a heart rate measurement and the RMS pictorial scale, respectively.RESULTS: The intragroup comparison of heart rate and RMS scores for children allocated to the dental app group was statistically significant (P value ≤ 0.001). However, a significant reduction only occurred in the RMS scores, but not the heart rate measurements, in the TSD group. Conversely, there was an increase in heart rates in the TSD group.CONCLUSION: Educating the child prior to a dental procedure using a smartphone application such as Little Lovely Dentist can significantly alleviate the anticipatory anxiety and engage children in dental treatment during their first visit.

This review gives an overview of the current multifocal intraocular lenses (IOLs) landscape, in terms of the technology, benefits, and limitations of different premium IOLs, as well as significant clinical outcomes. Cataract is the most common cause of visual impairment in older adults. From 1980, the number of blind and visually impaired people have decreased due to cataract surgery. As the number of surgical procedures increases every year, patient demands have also changed with many patients expecting excellent visual acuity without glasses. Multifocal IOLs can provide spectacle-independence for near, intermediate, and distant vision tasks. Multifocal IOLs can be classified into bifocal, trifocal, and extended depth of focus multifocal IOLs. The ultimate goal of multifocal lenses includes reduced incidence of photic phenomena, and improved uncorrected near, intermediate, and far visual acuities for those working with computers and smartphones, as well as no contrast sensitivity loss. Although some patients have issues with halos and glare, overall patient satisfaction and quality of life are generally high after multifocal IOL implantation. Careful patient selection should be made to satisfy different individual needs.

BACKGROUND: Smoking is one of the most serious health problems worldwide. The aim of this systematic review was to demonstrate the effect of text messaging-based interventions on smoking cessation.METHODS: Electronic databases were searched using specific key terms. The inclusion criteria were (1) articles that employed a randomized controlled trial and (2) articles that examined the effect of text messaging interventions on smoking cessation. However, studies employing multimedia messaging service and smartphone apps were excluded.RESULTS: In total, six randomized controlled trial studies with seven interventions were included in this systematic review. Of these six studies, almost all concluded that text-messaging interventions had no significant effect on smoking cessation. However, one study conducted in England revealed that text messaging intervention groups had a higher rate of six-month prolonged abstinence from smoking than did the control group.CONCLUSION: Text messaging interventions could be effective for those who want to quit smoking. We aimed to determine the effectiveness of using text messaging interventions for smoking cessation. However, there were only six studies that employed randomized controlled trials to determine such effectiveness. More studies on the effect of text messaging interventions for smoking cessation using subjects from various age groups and socioeconomic backgrounds are needed in the future.
