PURPOSE: This study was conducted to investigate the relationship between short message service and social media use, and sexual intercourse of high school students in Cambodia. METHODS: Four hundred and eighty-three high school students from three schools in rural provinces were interviewed with structured questionnaires. RESULTS: Sexual intercourse was found significantly more frequent among male students than among female students (p=.001), among alcohol drinkers than among non-drinkers (p<.001), among those who were not taking pictures with mobile phones than among those who were (p=.045), and among those who were exchanging SMS between boyfriend and girlfriend than among those who were not (p=.006). The students who were sending SMS by mobile phones were 5.83 times as likely to have sexual intercourse as their counterparts (p=.020), who were taking pictures with mobile phone were 0.04 times as likely as those who were not (p=.045) and the odds ratio was 15.19 times as high in alcohol drinkers as in non-drinkers (p=.001). CONCLUSIONS: Efforts should be made to encourage positive and effective use of social media among adolescents to maintain their sexual health.

text-align: justify;">OBJECTIVES: This study aimed to determine the effect of a Teleconsultation Program on health care provider and patient satisfaction regarding health care delivery. It is a descriptive cohort that described the satisfaction of health care providers and patients with the combined web (moodle) and Short Message Service (SMS)-based system of teleconsultation of the ADZU-SOM.

text-align: justify;">METHODS: This is a prospective cohort that included Municipal Health Officers from Region IX and Sulu and their patients. Questionnaires on satisfaction with the Teleconsultation program was given and filled up. Utilization of the mode of teleconsultation was monitored.

text-align: justify;">RESULTS: The study included 8 municipal health officers and 39 patients who completed questionnaires on satisfaction with the Teleconsultation program. Only 35% of physician-respondents and 36.4% of patient-respondents returned the questionnaires. The most common method of referring is through mobile phone SMS. High satisfaction rating was noted by both health providers and patients but concerns were raised regarding the costs of the system. The respondents felth that privacy issues were kept confidential with the system.

text-align: justify;">CONCLUSION: In conclusion, given the preference for mobile phones among Filipino rural physicians in municipal health units, telemedicine applications should be developed specifically for use in that platform.

Technological advances of mankind, through the development of electrical and communication technologies, have resulted in the exposure to artificial electromagnetic fields (EMF). Technological growth is expected to continue; as such, the amount of EMF exposure will continue to increase steadily. In particular, the use-time of smart phones, that have become a necessity for modern people, is steadily increasing. Social concerns and interest in the impact on the cranial nervous system are increased when considering the area where the mobile phone is used. However, before discussing possible effects of radiofrequency-electromagnetic field (RF-EMF) on the human body, several factors must be investigated about the influence of EMFs at the level of research using in vitro or animal models. Scientific studies on the mechanism of biological effects are also required. It has been found that RF-EMF can induce changes in central nervous system nerve cells, including neuronal cell apoptosis, changes in the function of the nerve myelin and ion channels; furthermore, RF-EMF act as a stress source in living creatures. The possible biological effects of RF-EMF exposure have not yet been proven, and there are insufficient data on biological hazards to provide a clear answer to possible health risks. Therefore, it is necessary to study the biological response to RF-EMF in consideration of the comprehensive exposure with regard to the use of various devices by individuals. In this review, we summarize the possible biological effects of RF-EMF exposure.

OBJECTIVE: This study aims to investigate the current usage status and identify the needs of mobile devices in the geriatric population, thus grasping the accessibility and possibility of mobile devices which can be positively used to allow them to obtain health information and manage their mental health. METHODS: All self-reported questionnaires, such as demographics, mobile phone usage, and several mental health-related scales, were completed by two elderly groups (14 males ; aged over 60, mean=73) who visited Seodaemun-gu center for dementia: 1) 54 feature phone and 2) 57 smartphone users. RESULTS: The results revealed that they have had the need to receive health information and healthcare particularly on psychiatric disorders such as dementia, geriatric depression, and anxiety. The relation between wireless calling plan and the two groups was significant. The two groups showed a significant difference only in the Short form of Geriatric Depression Scale (SGDS) score; The feature phone group had significantly higher SGDS score than the smartphone group did. CONCLUSION: As the elderly mobile phone users showed a high level of need for health information and healthcare via their own mobile phones, the data of this study are expected to serve as a foundation for the development of elderly-friendly mobile applications and programs.

Three of ten teenagers in Korea are addicted to mobile phones. The aim of this study was to examine the relationship between mobile phone addiction and the incidence of poor sleep quality and short sleep duration in adolescents. We used longitudinal data from the Korean Children & Youth Panel Survey conducted by the National Youth Policy Institute in Korea (2011–2013). A total of 1,125 students at baseline were included in this study after excluding those who already had poor sleep quality or short sleep duration in the previous year. A generalized estimating equation was used to analyze the data. High mobile phone addiction (mobile phone addiction score > 20) increased the risk of poor sleep quality but not short sleep duration. We suggest that consistent monitoring and effective intervention programs are required to prevent mobile phone addiction and improve adolescents' sleep quality.

PURPOSE: This study was conducted to investigate the effects of variations in arm swing during gait on movement of the trunk and pelvis. During the gait task, the angle of the trunk and pelvic rotation were analyzed according to arm swing conditions. METHODS: Seventeen healthy males participated in this study. All subjects were analyzed for gait on a treadmill three times each under three different types of arm swing conditions – natural arm swing, restricted arm swing using a phone, restricted swing in both arms. 3-D motion analysis systems were used to collect and analyze the kinematic data of trunk and pelvic movements, and repeated one-way ANOVA was used to compare the trunk and pelvic kinematic data and symmetry index. The level of significance was α=0.05. RESULTS: The results showed kinematic differences in trunk and pelvic during gait based on the arm swing conditions. Specifically, there were significant differences in trunk rotation, left and right trunk rotation and symmetry index of trunk rotation during gait among the three arm swing conditions. ROM was used to calculate a symmetry index (SI) based on the average left and right trunk rotation in which a value closer to zero indicated better balance. The SI obtained for arm swing restricted with the phone was closer to –1 than the other conditions. CONCLUSION: Restricted arm swing due to use of a phone had the possibility to induce instability of postural control while walking, which could be seen to suggest a risk of falling during gait.

OBJECTIVES: This study was conducted to investigate providers' perspectives on current challenges in implementing a program for prevention and management of childhood obesity and adoption of mobile phone as a potential solution of leveraging multimodal delivery and support in a school setting. METHODS: The qualitative data were collected through face-to-face in-depth interviews with 23 elementary-school teachers, 6 pediatricians, and 6 dieticians from community health centers and analyzed using a qualitative research methodology. RESULTS: Current challenges and potential solutions of obesity-prevention and -management program for obesity program for elementary school children were deduced as two themes each. Lack of tailored intervention due to limited recipient motivation, lack of individualized behavioral intervention, and different environmental conditions can be solvable by mobile technology-based personalized intervention which brings about interactive recipient participation, customized behavioral intervention, and ubiquitous accessibility. Lack of sustainable management due to stigmatization, limited interactions between program providers and inconsistent administrative support can be handled by multimodal support based on school setting using mobile platform providing education of health promoting behaviors toward larger scale and interactive networking between program participants, and minimizing administrative burden. CONCLUSIONS: Adoption of mobile-based health management program may overcome current limitations of child obesity program such as lack of tailored intervention and sustainable management via personalized intervention and multimodal supports although some concerns such as increased screen time need to be carefully considered in a further study.

OBJECTIVES: The aim of this study was to model the avoidable burden of the risk factors of road traffic crashes in Iran and to prioritize interventions to reduce that burden. METHODS: The prevalence and the effect size of the risk factors were obtained from data documented by the traffic police of Iran in 2013. The effect size was estimated using an ordinal regression model. The potential impact fraction index was applied to calculate the avoidable burden in order to prioritize interventions. This index was calculated for theoretical, plausible, and feasible minimum risk level scenarios. The joint effects of the risk factors were then estimated for all the scenarios. RESULTS: The highest avoidable burdens in the theoretical, plausible, and feasible minimum risk level scenarios for the non-use of child restraints on urban roads were 52.25, 28.63, and 46.67, respectively. In contrast, the value of this index for speeding was 76.24, 37.00, and 62.23, respectively, for rural roads. CONCLUSIONS: On the basis of the different scenarios considered in this research, we suggest focusing on future interventions to decrease the prevalence of speeding, the non-use of child restraints, the use of cell phones while driving, and helmet disuse, and the laws related to these items should be considered seriously.

OBJECTIVES: The objective of this study was to develop mobile phone application for image-based dietary assessment and evaluate satisfaction regarding respondent's use of the mobile phone application. METHODS: We developed a mobile phone application to assess dietary intakes using 24 hour dietary recall. After initial development, application was reviewed by ten adults and revised based on their comments. We recruited 192 volunteers (92 males, 100 females) to use the mobile phone application and to respond to a satisfaction survey. Participants were instructed to use the mobile phone application with fiducial marker five centimeter in width, length and two centimeter height at each eating occasion during designated 4 days, capturing 45° angle and 90° angle images of all food and beverage items before and after consumption. After using the mobile phone application for 4 days, participants were asked to complete an online questionnaire on the satisfaction of the mobile phone app. User satisfaction items composed of 12 questions of application user interface, 8 questions of emotional response, 9 questions of eating behavior in 5 likert scale. Participants were also asked to provide additional open-ended comments on the use of mobile phone application. Statistical analysis was performed by using the SPSS 23.0 (Statistical Package for the Social Science). RESULTS: The average user interface score was 2.82 ± 1.08, which was close to the ‘normal’ response. Responses for emotion and eating behavior also were borderline to the ‘normal’. CONCLUSIONS: This study found that the mobile phone application using 24-hour recall was acceptable to be used to assess dietary intakes for several days. However, there should be a need for such technology to be user-oriented instead of researcher-oriented. Easy and cost-effective new technology is needed for estimating the amounts of food eaten automatically when the photos are taken.
