INTRODUCTIONThere has been an explosive growth of Internet usage worldwide and this is expected to continue with its use becoming an integral part of everyday life. The Internet provides tremendous educational benefits; however, excessive Internet use can lead to negative outcomes such as poor school performance and social isolation.

MATERIALS AND METHODSThe survey consisted of a 69-item, anonymous, self-administered paper-and-pencil questionnaire. Data collected included demographic data, academic performance, social support and general wellbeing as well as questions pertaining to Internet use. For the purposes of our study, we defined Internet use of more than 5 hours a day as "excessive use".

RESULTSOf the 2735 adolescents who took part in the study, 1349 (49.3%) were male and 1383 (50.6%) were female. The mean age of the adolescents was 13.9 years [standard deviation (SD), 1.0]. A quarter of the adolescents surveyed (25%) reported that they did not access the Internet everyday, while 17.1% of adolescents reported using it for more than 5 hours every day. Excessive Internet use was associated with (i) no rules of Internet use at home (x2 = 313.1, P <0.001 ), (ii) less likelihood of having confidants (x2 = 15.8, P = 0.003), (iii) feelings of sadness or depression (x2 = 49.6, P <0.001) and (iv) perceived poorer grade/school work (x2 = 226.1, P <0.001).

CONCLUSIONSThe high figures of excessive Internet use (17.1%) reported in our study is not equivalent to Internet addiction as no diagnostic instruments were used. However, school counsellors and teachers need to be made aware of the prevalence of and problematic behaviours associated with excessive Internet use. Training and resources should also be made available to parents and caregivers so that they can play a greater role in setting boundaries and detecting early warning signs.

INTRODUCTIONThis study aims to examine the pattern of services utilisation and the factors associated with help-seeking behaviour among those with mental disorders in the multi-ethnic Asian population of Singapore.

MATERIALS AND METHODSA household survey was carried out on a nationally representative sample of the adult (18 years and above) resident population. The main instrument used to establish the diagnosis of mental disorders and the services sought was the Composite International Diagnostic Interview version 3.0 (CIDI 3.0). The 'services' component of the instrument contains questions, which examine service utilisation for mental health problems.

RESULTSA total number of 6616 completed respondents constituted a representative sample of the adult resident population in Singapore. Only 31.7% of those with mental disorders had sought help: 15.7% from mental health providers, 8.4% from general practitioners, and 7.6% from religious/ spiritual advisors or other healers. Among respondents with severe disability across any disorder assessed in our survey, 50.1% had sought help from some service in the past 12 months. Individuals with moderate or mild levels had lower rates of consultation, i.e. 35.4% and 30.6% respectively. The rate of using the Internet as a source of help was low in this population.

CONCLUSIONThere is a need to engage and work collaboratively with healthcare providers (including religious and spiritual healers) in the community to detect, assess and treat those with mental illness. More general practitioners need to be involved, and the role of the Internet also requires further consideration as a source for help.

OBJECTIVES: This study was performed to consider the association between Internet using time for non-educational purposes and adolescent health, and to examine how health status differs between Internet users and non-users. METHODS: We analyzed 2009 data from the Korea Adolescent Risk Behavior Web-Based Survey, conducted on a nationally representative sample of students in grades 7 to 12. A total of 75 066 adolescents were categorized into four groups according to their Internet using time excluding using for educational purposes: non-Internet users (NIUs), occasional Internet users (OIUs) (<1 h/d), moderate Internet users (MIUs) (> or =1 and <2 h/d), and heavy Internet users (HIUs) (> or =2 h/d). Health factors included eight health risk behavior indices, four mental health indices and six physical health indices. RESULTS: The distribution of Internet use was as follows: NIUs 17.4%, OIUs 68.1%, MIUs 12.7%, and HIUs 1.7%. In multivariate analysis, using OIUs as a reference, U- or J-shaped associations were observed for five health risk behavior indices (current smoking, current drinking, drug abuse, sexual intercourse, sedentary behavior on weekdays) and four mental health indices (stressed, depressed, suicidal ideation, attempted suicide) in both genders. After removing confounding effects, including age, region, school type, subjective school record, subjective economic status, presence of parents, living with family, and sedentary behavior, these associations were still observed. CONCLUSIONS: Health professionals should consider both Internet non-users (for non-educational purposes) and heavy users to be high-risk groups in terms of health status. Also, more well-designed studies are needed to clarify what factors are working in these nonlinear associations.

Real-time data reporting in clinical research networks can provide network members through interim analyses of the registered data, which can facilitate further studies and quality improvement activities. The aim of this report was to describe the building process of the data display system (DDS) of the Korean Neonatal Network (KNN) and its basic structure. After member verification at the KNN member's site, users can choose a variable of interest that is listed in the in-hospital data statistics (for 90 variables) or in the follow-up data statistics (for 54 variables). The statistical results of the outcome variables are displayed on the HyperText Markup Language 5-based chart graphs and tables. Participating hospitals can compare their performance to those of KNN as a whole and identify the trends over time. Ranking of each participating hospital is also displayed in terms of key outcome variables such as mortality and major neonatal morbidities with the names of other centers blinded. The most powerful function of the DDS is the ability to perform 'conditional filtering' which allows users to exclusively review the records of interest. Further collaboration is needed to upgrade the DDS to a more sophisticated analytical system and to provide a more user-friendly interface.

This investigation was made on the characteristic of the N400 event-related potentials in excessive internet users by analyzing the N400 difference between the excessive internet users (trial team) and normal subjects (control team); the aim was to provide a theoretic basis for the diagnosis and treatment of excessive internet users. Ten right-handed excessive internet users and ten healthy right-handed volunteers aged 20 to 25 years were recruited to attend the experimentation of single Chinese character with semantically matching or mismatching ending strokes. The N400 displayed obvious difference between the excessive internet users and normal subjects when they were confronted with mis-matching ending strokes of single simple Chinese character. The N400 amplitude of the trial team was significantly lower than that of the control team (P<0.05), and the N400 latency of the trial team was significantly earlier than that of the control team (P<0.05). In addition, the distribution of the N400 in the brain was more wide-spread in the control team than in the trial team. These results showed there was significant difference in N400 between the excessive internet users and the normal subjects.

OBJECTIVES: The purpose of the study was to identify a gap between consumer characteristics and utilization of health information on the Internet. METHODS: A telephone survey of nationally representative samples was conducted using structured questionnaires, and 1,000 of the 1,189 responses obtained were included in our analysis. The following variables were included in the analysis as potential predictors of health information use on the Internet: predisposing factors such as gender, age, and education status; enabling factors such as region and monthly household income; consumer need for health information; and attitude to health. Multiple logistic regression analysis was used to evaluate the association between utilization rate and the potential predictors. RESULTS: Thirty-nine percent of consumers had obtained health information on the Internet over a one-year period. The utilization rates were higher for consumers who were young, educated, worked in the office setting, had higher incomes, wanted health information, and were able to use the Internet. The utilization rate was 5.35 times higher in the younger group (20-30 years) than in the elderly group (95% CI=2.21-12.97); 2.21 times higher for office workers than for manual workers (95% CI=1.16-4.20); 3.61 times higher for college graduates than for middle school graduates and below (95% CI=1.07-11.59); 1.99 times higher for people with monthly household incomes over 3,000,000 won than for those with monthly household incomes below 1,500,000 won (95% CI=1.01-3.92). CONCLUSIONS: There needs to be a paradigm shift, with consideration of not only Internet accessibility in the digital age, but also consumer ability and attitudes toward utilization of health information.

OBJECTIVES: To explore the information sources and knowledge on infant vaccinations of pro-vaccination community members and anti- accination community members on the internet. METHODS: An online survey of 245 parents from three pro-vaccination communities and 92 parents from one antivaccination community was conducted from June 7 to June 23, 2006. RESULTS: Parents from pro-vaccination communities usually gained the information regarding vaccination efficacy and risk mainly from healthcare providers (49.8%) and mass media (47.7%). Pro-vaccination community members considered healthcare providers as the most credible sources of information on vaccination, whereas the anti-vaccination community members usually gained their information regarding vaccine efficiency and risk from Internet child-care cafes and online vaccination communities. Parents of the anti-vaccination community considered the internet as the most credible information source (77.6% for efficacy, 94.8% for risk). In addition, the major reason why anti-vaccination community members didn't vaccinate and, will not vaccinate, was concern about possible side effects of the vaccine. The knowledge level on infant vaccination, education and economic status was higher in the anti-vaccination community. CONCLUSIONS: On-line communities concerned with vaccination are getting popular. The influence of antivaccination parents on the Internet is expected to be high. The government and healthcare providers need to increase their efforts to improve the credibility of information about vaccination. Our findings suggest that online communication regarding vaccinations needs to be considered as a means to increase vaccination rates.

OBJECTIVEThis study aimed to determine the prevalence of short message system (SMS) and internet usage in patients visiting the SingHealth Polyclinics and to measure patients' acceptance of using these technologies in healthcare delivery.

MATERIALS AND METHODSA representative sample of patients visiting the 9 SingHealth Polyclinics were interviewed in-person by trained medical students. Collected information included demographic characteristics, access to and usage of mobile phone/SMS and internet, as well as acceptance and concerns on using these technologies in primary healthcare delivery.

RESULTSAmong 705 patients surveyed (mean age: 54.6 years, female: 50.6%, response rate: 92%), 407 (57.7%) were SMS users and 158 (22.4%) were internet users. Two hundred and eighty-four of 412 SMS and/or internet users (40.3% of the entire sample) were comfortable with the use of these technologies in healthcare delivery. Malay or Indian ethnicity, better education, and visiting the clinic for acute symptoms or screening were factors positively associated with willingness to use such technologies. The main concerns associated with the use of SMS and internet in healthcare delivery were preference for in-person consultation with a doctor (23.5%), reduced patient-doctor interaction (23.0%), and increased healthcare cost (20.8%).

CONCLUSIONThe present prevalence of SMS and internet usage among patients visiting the SingHealth Polyclinics and their concerns towards use of these technologies in healthcare delivery do not support current widespread implementation of services entailing SMS and internet in the study sites.
