Prevalence of dry eye disease among IT students in Pakistan

BACKGROUND

Dry eye disease (DED) is a common tear film disorder caused by decreased tear production or increased tear evaporation. The increased use of computers in the workplace has brought about the development of ocular health concerns, including dry eye disease. Therefore, this study was designed to determine the prevalence of DED associated with computer work and recommend preventing or reducing its development. This study investigated the prevalence of DED among IT students in Dera Ghazi Khan.

METHODS

A cross-sectional descriptive study was conducted among 327 undergraduate students of the IT department in the district of Dera Ghazi khan over 5 months from September 2021 to January 2022. DED was assessed subjectively with Ocular Surface Disease Index. Data were analysed using SPSS version 21. The quantitative analysis was presented as mean and standard deviation, and qualitative variables were introduced in frequency and percentages. The chi-square test (Fisher's exact test) was used to study the significance of associations between dependent and independent variables.

RESULTS

The mean age of the participants was 20.25 ± 1.305 years (range 17-25). The prevalence of DED among computer programmers was 47.7%. This study showed that gender (p = 0.31), contact lens usage (p = 0.64), and duration of time spent on computer display units (p = 0.47) were not significant determinants of DED among computer programmers.

CONCLUSION

DED is prevalent among IT students, along with different symptoms. However, further studies are required to adequately measure the prevalence of DED during longer exposure time to computer screens and explore environmental risk factors.

Leisure-Time Television Viewing and Computer Use, Family History, and Incidence of Dementia

INTRODUCTION

Time spent on screen-based sedentary activities is significantly associated with dementia risk, however, whether the associations vary by family history (FHx) of dementia is currently unknown. We aimed to examine independent associations of two prevalent types of screen-based sedentary activities (television [TV] viewing and computer use) with dementia and assess the modifying effect of FHx.

METHODS

We included 415,048 individuals free of dementia from the UK Biobank. Associations of TV viewing, computer use, and FHx with dementia risk were determined using Cox regression models. We estimated both multiplicative- and additive-scale interactions between TV viewing and computer use and FHx.

RESULTS

During a median follow-up of 12.6 years, 5,549 participants developed dementia. After adjusting for potential confounding factors, we observed that moderate (2-3 h/day; hazard ratio [HR] 1.13, 95% confidence interval 0.03-1.23) and high (>3 h/day; 1.33, 1.21-1.46) TV viewing was associated with a higher dementia risk, compared with low (0-1 h/day) TV viewing. Using restricted cubic spline models, the relationship of TV viewing with dementia was nonlinear (relative to 0 h/day; p for nonlinear = 0.005). We found that >3 h/day of TV viewing was associated with a 42% (1.42, 1.18-1.71) higher dementia risk in participants with FHx while a 30% (1.30, 1.17-1.45) in those without FHx. For computer use, both low (0 h/day; 1.41, 1.33-1.50) and high (>2 h/day; 1.17, 1.05-1.29) computer use were associated with elevated dementia risk, compared with moderate (1-2 h/day) computer use. We observed a J-shaped relationship with dementia (relative to 2 h/day; p for nonlinear <0.001). Compared with 1-2 h/day of computer use, the HRs of dementia were 1.46 (1.29-1.65) and 1.10 (0.90-1.36) for 0 h/day and >2 h/day of computer use in participants with FHx, respectively, while the corresponding HRs were 1.40 (1.30-1.50) and 1.19 (1.06-1.33) in those without FHx. We observed a positive additive interaction (RERI 0.29, 0.06-0.53) between computer use and FHx, while little evidence of interaction between TV viewing and FHx.

CONCLUSIONS

The time spent on TV viewing and computer use were independent risk factors for dementia, and the adverse effects of computer use and FHx were additive. Our findings point to new behavioral targets for intervention on preventing an early onset of dementia, especially for those with FHx.

Nursing Students' Computer Anxiety and Attitudes Before and During the COVID-19 Pandemic

Purpose of this research was to investigate how the COVID-19 pandemic affected the level of computer anxiety of nursing students and also their attitude related to computer use. A cross-sectional study was conducted in two periods, one before the COVID-19 pandemic (1st period) and the second during the COVID-19 pandemic (2nd period). The research instrument consisted of three parts, a questionnaire with questions about demographic and educational characteristics such as gender and semester of study, the Computer Anxiety Rating Scale (CARS), that used to assess the nursing students' levels of computer anxiety and the Computer Attitude Scale (CAS) that used to measure nursing students' positive and negative attitudes towards computers. Data from 957 undergraduate nursing students were obtained. Specifically, in the 1st period, 370 nursing students participated (38.66%), while in the 2nd period 587 (61.34%) undergraduates participated. The anxiety of participants during COVID-19 pandemic period was reduced compared to that of participants before the COVID-19 period. Respondents during the COVID-19 pandemic have fewer negative feelings towards computers, based on their answers in contrast to the participants in the study before the COVID-19 pandemic. Computer anxiety and attitudes have change among nursing students among COVID-19 pandemic. Nursing students after the implementation of online training are reporting positive feeling towards computer use and are more confident for their ICT skills.

Digital transformation: The role of computer use in employee health

This paper studies employee health in the context of digital transformation in Germany. While most studies have focused on mental health, we focus on physical health. Using pooled survey data, we estimate how an increased use of computers in the workplace relates to subjective health and work-related health complaints. We find that employees using the computer frequently report better subjective health and a significantly lower prevalence of back pain and physical exhaustion. After controlling for physical work exposures, the health-promoting effect of computer use is much smaller, suggesting that high computer use is associated with a less physically demanding work environment, which in turn relates to better (physical) health outcomes. While digital transformation seems to foster physical health, there are hints that mental health could deteriorate. Thus, the focus of occupational health is shifting towards the prevention of mental stress.

Genetic susceptibility, screen-based sedentary activities and incidence of coronary heart disease

BACKGROUND

Whether the associations of time spent in screen-based sedentary activities with CHD vary by genetic susceptibility is currently unknown. The objective of this study was to examine the interplay of genetic susceptibility to CHD and two prevalent types of screen-based sedentary activities (television [TV] viewing and computer use) for CHD incidence.

METHODS

This prospective cohort study included 373,026 individuals of European ancestry without prevalent CHD/stroke from UK Biobank data. Genetic susceptibility to CHD was assessed using weighted polygenic risk scores, calculated by summing the number of risk-increasing alleles among 300 single-nucleotide polymorphisms, multiplied by their corresponding effect estimates. TV viewing and computer use were assessed through touch-screen questionnaires. CHD incidence (n=9185) was adjudicated over a median 12.6-year follow-up.

RESULTS

Compared with ≥4h/day of TV viewing, the hazard ratio of CHD was 0.84 (95% confidence interval [CI] 0.79-0.90) and 0.94 (0.90-0.99) for ≤1h/day and 2-3h/day of TV viewing, respectively, after adjusting for confounders including the genetic risk. CHD hazards were higher for medium and high genetic risk than for low genetic risk. Across all levels of genetic risk including high-genetic risk, ≤1h/day of TV viewing had lower CHD hazards, compared with ≥4h/day: no evidence of interaction between genetic risk and TV viewing (p value: 0.362). Estimates of the population attributable fraction (PAF) suggested that 10.9% (95% CI 6.1-15.3%) of CHD could be prevented if TV viewing time were reduced to ≤1h/day, assuming causality. The PAF values were relatively larger for medium-to-high genetic risk than for low genetic risk, although the CIs were wide and overlapping. No associations were observed for computer use.

CONCLUSIONS

Less TV viewing time was associated with lower CHD risk independently of genetic risk. Clinical trials targeted at individuals with high genetic susceptibility should consider reducing TV viewing as as a behavioural target for prevention of an early onset of cardiovascular events.

Prevalence and risk factors for self-reported symptoms of carpal tunnel syndrome among hospital office workers: a cross-sectional study

OBJECTIVES

We aimed to determine the prevalence of self-reported symptoms of carpal tunnel syndrome (CTS) and associated risk factors among hospital office workers.

MATERIAL AND METHODS

This cross-sectional study was carried out between May and August 2021 with office workers actively working in a hospital in Izmir, Turkey. The Boston Carpal Tunnel Syndrome Questionnaire was used to evaluate the severity of self-reported CTS symptoms and their effect on the functional status of the participants.

RESULTS

The study included 151 people, 68.2% of whom were women. The CTS symptoms were reported by 74.1% of the participants, the majority of whom (73.2%) were women. These reported symptoms were mild in 43%, moderate in 24.5%, severe in 5.3%, and very severe in 1.3%. Significant differences were found between those with and without CTS symptoms regarding the age, body-mass index, a previous diagnosis of CTS, daily work hours, using a wrist-supported mousepad, and perceived workload (p < 0.05).

CONCLUSION

It was found that the CTS symptoms of office workers in the hospital were associated with occupational characteristics as well as individual factors. These risk factors should be taken into account while planning for future preventive and interventional measures in workplaces.

How Do Patients Want Us to Use the Computer During Medical Encounters?-A Discrete Choice Experiment Study

BACKGROUND

Primary care physicians (PCPs) now widely use electronic health records (EHRs) during medical encounters. Experts in clinical communication issued recommendations for a patient-centered use of EHRs. However, they have never been validated by patients themselves.

OBJECTIVE

To explore patients' preferences regarding physicians' EHR-related behaviors.

DESIGN

Discrete choice experiment study.

PATIENTS

French-speaking patients waiting for a medical consultation at two outpatient clinics in Geneva, Switzerland.

MAIN MEASURES

We invited patients to watch videos displaying 2 or 3 variations of four specific EHR-related behaviors and asked them to indicate which one they preferred. EHR-related behaviors were (1) typing: continuous/intermittent/handwriting in biomedical or psychosocial focused consultations; (2) maintaining contact while typing: visual/verbal/both; (3) signposting the use of EHR: with/without; (4) position of physicians' hands and bust: on the keyboard and towards the patient/away from the keyboard and towards the patient/on the keyboard and towards the screen.

KEY RESULTS

Three hundred thirty-six patients participated (response rate 61.4%). They preferred intermittent typing versus handwriting or continuous typing for biomedical issues (32.7%; 95% CI: 26.0-40.2% vs 31.6%; 95% CI: 24.9-39.0% or 14.9%; 95% CI: 10.2-21.1%) and psychosocial issues (38.7%; 95% CI: 31.6-46.3% vs 24.4% 95% CI: 18.4-31.5% or 17.9%; 95% CI; 12.7-24.4%). They favored visual and verbal contact (38.9%; 95% CI: 31.9-46.3%) over verbal (30.3%; 95% CI: 23.9-37.5%) or visual contact only (11.4%; 95% CI: 7.5-17.1%) while the doctor was typing. A majority preferred signposting the use of EHR versus no signposting (58.9%; 95% CI: 53.5-64.0% vs 34.8%; 95% CI: 29.9-40.1%). Finally, half of the patients (49.7%; 95% CI: 42.0-57.4%) favored the position with the physician's bust towards the patient and hands away from the keyboard.

CONCLUSIONS

Our study shows that patients' preferences regarding EHR-related behaviors are in line with most experts' recommendations. Such recommendations should be more consistently integrated into under- and postgraduate communication skills training.

Glaucoma and Computer Use: Do Contrast and Color Enhancements Improve Visual Comfort in Patients?

PURPOSE

To estimate the impact of glaucoma on computer use and to assess specific adaptations of the graphical interface to this form of visual impairment.

DESIGN

Prospective, experimental cohort study.

PARTICIPANTS

Forty-nine participants were recruited: 16 patients with primary open-angle glaucoma (mean ± SD, 62.7 ± 5.6 years of age), 17 age-matched participants (mean ± SD, 59.1 ± 8.3 years of age), and 16 young control participants (mean ± SD, 23.3 ± 2.1 years of age).

METHODS

An ophthalmologic examination before the study evaluated the level of visual loss (mean deviation), visual acuity (logarithm of the minimum angle of resolution units), and contrast sensitivity (CS) of the primary open-angle glaucoma patients. Each participant underwent the following measurements: an information technology (IT) experience questionnaire, a preference task monitored by eye tracking, and a feedback session. The experimental task was based on ecological computer scenes with 3 enhancement levels (low, medium, and high), determined by gradual modulation of contrast, luminance, and color. Participants were asked to select the most readable and comfortable stimulus among 4 images displayed on the screen: the original computer scene and 3 enhanced versions.

MAIN OUTCOME MEASURES

Clinical, oculomotor, and subjective data were computed together in a multivariate model by using a principal component analysis (PCA).

RESULTS

The PCA revealed 3 principal components accounting for 72% of the total variance of the data and showed a greater need for enhanced computer scenes in glaucoma patients, an equal preference for low and medium enhancement within the 3 groups, and significantly longer oculomotor behavior in the patient groups. Subjective reports of difficulty using IT because of vision were correlated with visual impairment and high enhancement preference. Contrast sensitivity was critical to explaining the main variations of the data. A reduced CS had a significant effect on the preference for enhanced computer scenes (r = -0.43; P < 0.002) and a less effective exploration velocity (r = 0.43; P < 0.002).

CONCLUSIONS

Glaucoma alters the global exploration of computer scenes. High enhancement of the graphical interface could improve visual comfort during computer use. Subjective patients' reports underline the importance of including IT questions in visual-related quality-of-life questionnaires.

Prevalence and risk factors of self-reported wrist and hand symptoms and clinically confirmed carpal tunnel syndrome among office workers in China: a cross-sectional study

Background

Carpal tunnel syndrome (CTS) is a common cause of pain, numbness and tingling in the wrist and hand region and is associated with repetitive wrist and hand use in office workers. However, scarce knowledge exists about the epidemiology of clinically confirmed CTS among Chinese office workers. This study aimed to investigate the prevalence of wrist/hand symptoms and CTS in office workers in China and to identify associated risk factors.

Methods

A cross-sectional survey was carried out in a metropolitan city in China involving 969 respondents (aged 17–49 years) from 30 workplaces. A questionnaire was distributed to each participant to collect their demographic, work-related physical and psychosocial factors, and wrist and hand symptoms. The wrist and hand pain/numbness symptoms were marked on a body chart and the nature and intensity of symptoms, nocturnal symptoms, as well as aggravating activities were also recorded. Clinically confirmed CTS cases were screened based on the history, Phalen’s test, Tinel Sign and skin sensation testing among symptomatic respondents. Logistic regression was employed to estimate the odds ratio (OR) and 95% confidence interval (95% CI) for the occurrence of self-reported wrist and hand symptoms and clinically confirmed CTS.

Results

The clinically confirmed CTS prevalence was 9.6%. The prevalence of wrist and hand symptoms were 22 and 15%, respectively. Frequently working in pain was associated with higher odds of CTS. Multivariate modelling adjusted for age and gender showed that prolonged computer use time and working without breaks were associated with presence of wrist/hand symptoms (adjusted ORs: 1.11 (95% CI 1.02–1.22) and 1.88 (95% CI 1.12–3.14)). Educational level was inversely associated with CTS and smoking was associated with wrist/hand complaints (adjusted OR: 2.20 (95% CI 1.19–4.07)).

Conclusions

The prevalence of work-related clinically confirmed CTS symptoms among young office workers in China is high. Frequently working in pain is closely associated with clinically confirmed CTS. Intense computer use and no breaks at work are associated with wrist and hand symptoms.

Relationship between screen time and sleep among Finnish preschool children: results from the DAGIS study

STUDY OBJECTIVES

To examine the associations between screen time, the time spent on different screen devices, and sleep in a sample of Finnish preschool children.

METHODS

The current study analyzed cross-sectional data from the DAGIS study carried out in Finland in 2015-2016 on 736 children aged 3-6 years. Parents reported in a 7-day diary the durations the child used screen devices daily, with separate details about watching TV or DVDs, using tablets or smartphones, and using computers. In addition, parents reported children's bedtimes and wake-up times, which were further used in calculating sleep duration. Parents answered questions regarding their child's sleep consistency. Statistical analyses included adjusted general linear modeling.

RESULTS

An hourly increase in total screen time was associated with 11 min later bedtime (p < 0.001) and 10 min shorter sleep duration (p < 0.001). More TV/DVD watching was associated with later bedtimes (p = 0.016) and a shorter sleep duration (p = 0.001). More smartphone/tablet use was associated with later bedtimes (p = 0.005), later wake-up times (p = 0.038), and weaker sleep consistency (p = 0.024). More computer use was associated with later bedtimes (p = 0.046). Results did not differ between genders.

CONCLUSIONS

Increased screen time was associated with later bedtimes and shorter sleep duration among preschool children. Adverse associations with sleep outcomes were found for each screen device. Attention should be paid to promoting balanced use of screens and regular sleep habits in young children.

Heavy Screen Use on Weekends in Childhood Predicts Increased Body Mass Index in Adolescence: A Three-Year Follow-Up Study

PURPOSE

We aimed to examine whether sedentary screen time changes when transitioning from childhood to adolescence and whether children's screen time, separately for school days and weekends, affects body mass index (BMI) in adolescents.

METHODS

This prospective 3-year follow-up study included 5,084 children with a mean (standard deviation) age of 11 (1) years at baseline and 14 (1) years at follow-up. Children reported screen time, more specifically, time spent viewing TV programs and using a computer outside school while sitting. We categorized children into light, medium, and heavy TV viewers and computer users separately for school days and weekends. We also calculated the age- and gender-specific BMI z-score (BMIz).

RESULTS

Time spent viewing TV changed from baseline to follow-up on school days and on weekends (p < .001 for both); the proportion of heavy TV viewers on school days (≥3 h/d) increased from 16% to 23% and on weekends (≥4 h/d) from 19% to 30%. Heavy TV viewers and computer users on both school days and on weekends had a higher BMIz 3 years later (p < .001 for all). After adjusting for age, gender, language, baseline BMIz, sleep duration, eating habits, exercise, and the other screen-time variables, heavy TV viewing on weekends remained significantly associated with an increased BMIz at follow-up (B = .078; p = .013).

CONCLUSIONS

The proportion of heavy screen users increases when transitioning from childhood to adolescence. Moreover, heavy screen use, especially on weekends in 11-year-old children, is associated with an increased BMI 3 years later.

Prevalence of primary headache disorders among information technology staff in China: the negative effects of computer use and other correlative factors

Background

To date, there have been very few studies that have explored the relationship between headaches and computer use. The chief aim of this study is to investigate the prevalence of primary headache disorders among informational technology staff and identify the potential factors contributing to it.

Methods

This is a cross-sectional study based on annual health checks of employees from the information technology industry. We identified 2216 information technology staff members from Beijing by stratified random sampling who met the inclusion criteria. All participants were initially required to have a physical examination, after which they complete a general situation questionnaire that included a headache screening question. Those who had suffered from headache within the previous year also completed the questionnaire developed by Lifting the Burden. The International Classification of Headache Disorders 3(ICHD-3) criteria was used for the diagnosis of headache.

Results

A total of 2012 valid questionnaires (males, 1544 [76.7%]; females, 468 [23.3%]) were obtained from 2216 participants for a response rate of 90.8%. A total of 619 participants were diagnosed with primary headache, the one-year prevalence of which was 30.8%. Regarding the classification of the primary headache, 152 participants suffered from migraine, with a one-year prevalence of 7.6%; 440 and 27 suffered from tension-type headache and unclassified headaches, with one-year prevalences of 21.9 and 1.3%, respectively. Multivariate regression analysis showed that female gender was a risk factor for migraine and tension-type headache (OR 3.21[95% CI 2.28–4.53] and 1.88[95% CI 1.47–2.40], respectively). Age was also related to migraine and tension-type headache. The 41–50 age group had 2.02 times the probability of migraine, and the 31–40 age group had 1.89 times the probability of tension-type headaches compared to the 18–30 age group. Obesity and excessive computer use (more than 12 h per day) were also factors contributing to tension-type headache (OR: 2.61[95% CI 1.91–3.56] and 1.63[95% CI 1.18–2.25], respectively).

Conclusions

The one-year prevalence of primary headache in this population was 30.8%. The prevalence of tension-type headache in this population was higher than that in the general Chinese population. The occurrence of primary headache is correlated with many factors, among which excessive computer use significantly contributed to the risk of tension-type headache.

Unrestricted prevalence of sedentary behaviors from early childhood

Background

Light and sedentary behaviors impose heavy challenges on societies. The objectives of this study are to identify child sedentary behaviors, and to examine the relationship between parent knowledge and behavioral style on children’s sedentary time in Iran.

Methods

This cross-sectional study was done among children and their parents selected randomly using multi-stage method, from 12 urban districts in Tabriz, Iran;2017. Data were collected through designing a multi-sectional questionnaire adopted from the Bjelland and previous studies to assess the time spent on sedentary behaviors among children/adolescents along with parent knowledge and behavioral style.

Results

From 480 children/adolescents and their parents 54.6% came from middle class families, and 55.62% were boys aged 2 to18. The percentage of time spent more than 120 min per day (min/d) on weekdays was for watching television (TV): (girls 24.4%, boys 21.0%), for playing computer and video games: (girls 38.7%, boys 54.7%), for electronic media communication (EMC): (girls 52.8%, boys 60.2%). The associated factors for watching TV: child age [12 years and above OR = 1.37; 95% CI = 0.53–3.54], parent knowledge [OR = 0.59, 95% CI = 0.35–0.99], and communicative styles [OR = 1.43, 95%CI = 1.11–1.86], and for playing computer and EMC: child age [5 years old and above OR = 4.83,95% CI =1.52–15.38, 12 years old and above OR = 13.76, 95% CI= 4.22–24.91], family socio-economic status [middle class OR = 2.52, 95% CI = 1.54–4.11, high class OR = 5.53, 95%CI = 1.80–15.89].

Conclusion

There is an urgent need to combat the unrestricted prevalence of sedentary behaviors among Iranian children/ adolescents who use computers and other electronic devices more than the recommended time every day from early childhood.

Parents should be provided with appropriate information about adverse effects of using electronic devices longer than recommended time by children. It is also essential to teach them beneficial communicative styles to monitor their children’s sedentary behaviors.

Training residents in patient-centred communication and empathy: evaluation from patients, observers and residents

BACKGROUND

Patient-centred communication and empathy are key enablers for patient-centred care. However, several studies suggest a downward trend regarding the empathic communication skills of physicians during medical residency. It is known that communication training can have a positive effect on patient-centred communication, empathy and relational skills. Training residents in patient-centred communication and empathy can be an opportunity to improve the patient-centred care. To evaluate the training a tri-focal perspective will be used.

METHODS

A 3-day training was developed to improve residents' patient-centred communication and empathy skills at an academic medical health centre, in the Netherlands. The training included: (1) the basics of patient-centred communication and empathy (through presentations, scientific literature), (2) practicing with actors, and (3) reflecting on residents' video recorded consultations (by themselves and communication experts). A pilot study with a pre-post design was conducted to evaluate the training from patient and observer perspectives. Semi-structured interviews were used to get insight into residents' perspective. Nine residents from different specialities followed the training and enrolled in the pilot study. During two random days consultations between residents and patients were video recorded. Patients were asked to fill in two questionnaires, indicating their perspective on residents' empathy and communication skills before as well as after the consultation. All video recorded consultations were coded to rate residents' communication skills, empathy, computer use and agenda-setting. Statistical analysis were performed using multilevel analysis.

RESULTS

A total of 137 eligible patients took part in the pilot study. Trained residents showed significant improvement in patient-rated empathy scores. According to observers, residents' computer use improved significantly after the training. The communication skills of trained residents did not improve significantly. Agenda setting by residents showed a downward trend. Almost all residents were satisfied with the training, especially with the video-feedback.

CONCLUSIONS

A brief training significantly increased residents' empathy scores according to patients and significantly decreased residents' computer use according to observers. These findings indicate that the quality of patient-centred care can be improved by integrating patient-centred communication into residency programs, at an academic medical health centre. The ultimate goal is to structurally embed the training in residents' education program.

Personal and behavioral correlates of total and domain-specific sedentary behaviors in older Taiwanese adults

BACKGROUND

Evidence of the harmful health effects of sedentary behavior is emerging; however, little is known about domain-specific sedentary behavior correlates. Thus, in this study, the personal and behavioral correlates of total and domain-specific sedentary behavior in older Taiwanese adults were identified.

METHOD

The sample comprised 1046 older adults (aged ≥65 years). Cross-sectional data on self-administered personal behavioral variables and time spent engaging in domain-specific sedentary behavior were obtained using computer-assisted telephone-based interviews. Binary logistic regression analyses were performed.

RESULTS

Those aged older than 75 years were less likely to have longer total sedentary, computer use, and transportation times. Compared to women, older men were more likely to have longer total sedentary and transportation times. Older adults with low educational levels were less likely to have longer total sedentary and computer use times but were more likely to have an excessive television (TV) viewing time (≥2 h/day). Older adults who lived alone and were overweight had a longer TV viewing time. Furthermore, unemployment was associated with an excessive TV viewing time and shorter transportation time. Older adults residing in nonmetropolitan areas had lower total sedentary, TV viewing, and computer use times. Older adults who engaged in insufficient leisure time physical activity were more likely to have longer total sedentary and transportation times.

CONCLUSIONS

Both common and distinct personal and behavioral factors were associated with total and domain-specific sedentary behavior. Interventions for reducing total and domain-specific sedentary behavior should focus on both common and distinct subgroups of the Taiwanese older population.

Insufficient Sleep Is Associated with Obesity and Excessive Screen Time Amongst Ten-Year-Old Children in Sweden

PURPOSE

This study investigated sleep, television, computer habits, and obesity in school-age children.

DESIGN AND METHODS

This was a cross-sectional self-report survey of 1260 children in grade 4 (mean age, 10.1) living in southern Sweden (49.1% boys). The heights and weights of 1097 (87.1%) of the children were recorded. Descriptive statistics, bivariate analyses, and multiple logistic regression were employed.

RESULTS

The median length of self-reported sleep on weeknights was 9.5h. Approximately 40% of the children reported receiving <9h of sleep. The median bedtime was 9PM (21:00). On weekends, the median bedtime was 1 h later, and they delayed getting up by 1.5h. The median time spent watching TV and using a computer was 1 h each. The prevalence of being overweight (including obesity) was 18%. Insufficient sleep (<9h) was associated with being overweight, watching TV, or using a computer for two or more hours each day, difficulty falling asleep, and being tired at school.

CONCLUSIONS

School-age children who receive less sleep are more likely to be overweight and report excessive television and computer use. A strong and urgent need exists to highlight the importance of healthy sleep and media habits. It is challenging for pediatric nurses and school nurses to teach children and their families about healthy sleep and media habits.

Weekly observations of online survey metadata obtained through home computer use allow for detection of changes in everyday cognition before transition to mild cognitive impairment

INTRODUCTION

Subtle changes in instrumental activities of daily living often accompany the onset of mild cognitive impairment (MCI) but are difficult to measure using conventional tests.

METHODS

Weekly online survey metadata metrics, annual neuropsychological tests, and an instrumental activity of daily living questionnaire were examined in 110 healthy older adults with intact cognition (mean age = 85 years) followed up for up to 3.6 years; 29 transitioned to MCI during study follow-up.

RESULTS

In the baseline period, incident MCI participants completed their weekly surveys 1.4 hours later in the day than stable cognitively intact participants, P = .03, d = 0.47. Significant associations were found between earlier survey start time of day and higher memory (r = -0.34; P < .001) and visuospatial test scores (r = -0.37; P < .0001). Longitudinally, incident MCI participants showed an increase in survey completion time by 3 seconds per month for more than the year before diagnosis compared with stable cognitively intact participants (β = 0.12, SE = 0.04, t = 2.8; P = .006).

DISCUSSION

Weekly online survey metadata allowed for detection of changes in everyday cognition before transition to MCI.

Risk factors of non-specific neck pain and low back pain in computer-using office workers in China: a cross-sectional study

OBJECTIVES

Several studies have found that inappropriate workstations are associated with musculoskeletal disorders. The present cross-sectional study aimed to identify the risk factors of non-specific neck pain (NP) and low back pain (LBP) among computer-using workers.

DESIGN

Observational study with a cross-sectional sample.

SETTING

This study surveyed 15 companies in Zhejiang province, China.

PARTICIPANTS

After excluding participants with missing variables, 417 office workers, including 163 men and 254 women, were analyzed.

OUTCOME MEASURES

Demographic information was collected by self-report. The standard Northwick Park Neck Pain Questionnaire and Oswestry Low Back Pain Disability Index, along with other relevant questions, were used to assess the presence of potential occupational risk factors and the perceived levels of pain. Multinomial logistic regression analysis, adjusted for age, sex, body mass index, education, marital status and neck/low back injury, was performed to identify significant risk factors.

RESULTS

Compared with low-level NP, the computer location (monitor not in front of the operator, but on the right or left side) was associated with ORs of 2.6 and 2.9 for medium- and high-level NP, respectively. For LBP, the computer location (monitor not in front) was associated with an OR of 3.2 for high-level pain, as compared with low-level pain, in females. Significant associations were also observed between the office temperature and LBP (OR 5.4 for high vs low), and between office work duration ≥5 years and NP in female office workers (OR 2.7 for medium vs low).

CONCLUSIONS

Not having the computer monitor located in front of the operator was found to be an important risk factor for NP and LBP in computer-using female workers. This information may not only enable the development of potential preventive strategies but may also provide new insights for designing appropriate workstations.

Longitudinal changes in physical activity and sedentary time in adults around retirement age: what is the moderating role of retirement status, gender and educational level?

Background

The start of retirement is an important stage in an (older) adult’s life and can affect physical activity (PA) and/or sedentary behaviors, making it an ideal period to implement health interventions. To identify the most optimal timing of such interventions it is important to determine how PA and sedentary behaviors change not only when making the transition to retirement, but also during the first years of retirement. The main study aim was to examine whether PA and sedentary behaviors change differently in retiring adults compared with recently retired adults. A second aim was to examine potential moderating effects of gender and educational level.

Methods

A longitudinal study was conducted in Ghent, Belgium. Baseline measurements took place in 2012–2013 and follow-up data were collected 2 years later. In total, 446 adults provided complete data at both time points. Of the participants 105 adults were not retired at baseline but retired between baseline and follow-up (i.e. retiring) and 341 were already retired at baseline (i.e. recently retired). All participants completed a questionnaire on PA, sedentary behaviors, socio-demographic factors and physical functioning. Repeated measures MANOVAs were conducted in SPSS 22.0. to analyze the data.

Results

Leisure-time cycling increased over time in retiring adults, but decreased in recently retired adults (p < 0.01). (Voluntary) work-related walking and moderate-to-vigorous PA decreased strongly in retiring adults, while slight increases were found in recently retired adults (p < 0.001 and p < 0.01). Passive transport decreased more strongly in recently retired than in retiring adults (p < 0.05), and computer use increased more in retiring adults than in the recently retired group (p < 0.001). Low-educated recently retired adults had the strongest decrease in walking for transport (p < 0.05) and strongest increase in TV viewing time (p < 0.01) and computer use (p < 0.10). For gender, almost no moderating effects were found.

Conclusions

Future interventions should focus on PA and/or specific sedentary behaviors in retiring adults, but should definitely include long-term follow-up, as recently retired adults seem to be prone to lapse into an unhealthy lifestyle. Specific attention should be paid to low-educated adults as they are particularly susceptible to a decrease in PA and increased TV viewing time and computer use.

Computer use at work is associated with self-reported depressive and anxiety disorder

Background

With the development of technology, extensive use of computers in the workplace is prevalent and increases efficiency. However, computer users are facing new harmful working conditions with high workloads and longer hours. This study aimed to investigate the association between computer use at work and self-reported depressive and anxiety disorder (DAD) in a nationally representative sample of South Korean workers.

Methods

This cross-sectional study was based on the third Korean Working Conditions Survey (2011), and 48,850 workers were analyzed. Information about computer use and DAD was obtained from a self-administered questionnaire. We investigated the relation between computer use at work and DAD using logistic regression.

Results

The 12-month prevalence of DAD in computer-using workers was 1.46 %. After adjustment for socio-demographic factors, the odds ratio for DAD was higher in workers using computers more than 75 % of their workday (OR 1.69, 95 % CI 1.30−2.20) than in workers using computers less than 50 % of their shift. After stratifying by working hours, computer use for over 75 % of the work time was significantly associated with increased odds of DAD in 20–39, 41–50, 51–60, and over 60 working hours per week. After stratifying by occupation, education, and job status, computer use for more than 75 % of the work time was related with higher odds of DAD in sales and service workers, those with high school and college education, and those who were self-employed and employers.

Conclusions

A high proportion of computer use at work may be associated with depressive and anxiety disorder. This finding suggests the necessity of a work guideline to help the workers suffering from high computer use at work.

Psychiatrists' Comfort Using Computers and Other Electronic Devices in Clinical Practice

This report highlights findings from the Study of Psychiatrists' Use of Informational Resources in Clinical Practice, a cross-sectional Web- and paper-based survey that examined psychiatrists' comfort using computers and other electronic devices in clinical practice. One-thousand psychiatrists were randomly selected from the American Medical Association Physician Masterfile and asked to complete the survey between May and August, 2012. A total of 152 eligible psychiatrists completed the questionnaire (response rate 22.2 %). The majority of psychiatrists reported comfort using computers for educational and personal purposes. However, 26 % of psychiatrists reported not using or not being comfortable using computers for clinical functions. Psychiatrists under age 50 were more likely to report comfort using computers for all purposes than their older counterparts. Clinical tasks for which computers were reportedly used comfortably, specifically by psychiatrists younger than 50, included documenting clinical encounters, prescribing, ordering laboratory tests, accessing read-only patient information (e.g., test results), conducting internet searches for general clinical information, accessing online patient educational materials, and communicating with patients or other clinicians. Psychiatrists generally reported comfort using computers for personal and educational purposes. However, use of computers in clinical care was less common, particularly among psychiatrists 50 and older. Information and educational resources need to be available in a variety of accessible, user-friendly, computer and non-computer-based formats, to support use across all ages. Moreover, ongoing training and technical assistance with use of electronic and mobile device technologies in clinical practice is needed. Research on barriers to clinical use of computers is warranted.

Postural dynamism during computer mouse and keyboard use: A pilot study

Prolonged sedentary computer use is a risk factor for musculoskeletal pain. The aim of this study was to explore postural dynamism during two common computer tasks, namely mouse use and keyboard typing. Postural dynamism was described as the total number of postural changes that occurred during the data capture period. Twelve participants were recruited to perform a mouse and a typing task. The data of only eight participants could be analysed. A 3D motion analysis system measured the number of cervical and thoracic postural changes as well as, the range in which the postural changes occurred. The study findings illustrate that there is less postural dynamism of the cervical and thoracic spinal regions during computer mouse use, when compared to keyboard typing.

Influence of indoor and outdoor activities on progression of myopia during puberty

The purpose of this study was to investigate whether time spent on indoor and outdoor activities or the other possible risk factors including age, gender, parental history, and initial refraction was associated with progression of myopia, during puberty. Fifty eyes of 50 myopic children aged 9-14 years were enrolled in the study. The parents were interviewed to determine the amounts of time in hours per day spent on reading and writing, using computer, watching TV, and outdoor activities (i.e., sports, games, or being outdoor with no activities) on an average day. The annual myopia progression rate (diopters per year) was calculated for each subject and was used in the statistical analyses. The mean initial age of the subjects was 10.9 ± 1.5 (ranging from 9 to 14) years. The mean follow-up period was 33.3 ± 10.3 (ranging from 17 to 55) months. There was a significant increase in the mean myopia value of the subjects after follow-up period (p < 0.001). The mean daily time spent on reading and writing and initial refraction value were independently associated with annual myopic progression rate. On the other hand, age, gender, parental myopia, and the mean daily times spent on computer use, watching TV, and outdoor activities had no correlations with annual myopia progression rate. The present study showed that myopia progression was associated with time spent on reading and writing and initial refraction value, during puberty. However, myopia progression was not associated with parental myopia, age, gender, and daily times spent on using computer, watching TV, and outdoor activities.

An integrative review of coping related to problematic computer use in adolescence

OBJECTIVES

Problematic computer use is the use of computer technology that may be health-endangering and may cause immediate or later negative physical or psychological health outcomes or disturb well-being in users. The main purpose of this study was to review current empirical research on coping strategies which adolescents apply in the context of problematic computer use and the coping-relevant impacts of problematic computer use.

METHODS

An integrative review of empirical studies using the Web of Science, Google Scholar, reference lists and forward tracking was conducted. Of the 404 articles identified, 28 peer-reviewed, full-text articles that directly addressed coping in relation to problematic Internet use, computer overuse and cyberbullying were included in the review.

RESULTS

This review identified the structure of specific coping strategies related to problematic computer use as well as the general patterns of relationships between reviewed instances of problematic computer use, situational coping and dispositional coping.

CONCLUSIONS

Instrumental action and talking with others were the most frequent strategies used by adolescents to cope with cyberbullying. The structure of the coping strategies related to problematic Internet use and computer overuse is highly differentiated, revealing a new and promising area for future research.

A vertical mouse and ergonomic mouse pads alter wrist position but do not reduce carpal tunnel pressure in patients with carpal tunnel syndrome

Non-neutral wrist positions and external pressure leading to increased carpal tunnel pressure during computer use have been associated with a heightened risk of carpal tunnel syndrome (CTS). This study investigated whether commonly used ergonomic devices reduce carpal tunnel pressure in patients with CTS. Carpal tunnel pressure was measured in twenty-one patients with CTS before, during and after a computer mouse task using a standard mouse, a vertical mouse, a gel mouse pad and a gliding palm support. Carpal tunnel pressure increased while operating a computer mouse. Although the vertical mouse significantly reduced ulnar deviation and the gel mouse pad and gliding palm support decreased wrist extension, none of the ergonomic devices reduced carpal tunnel pressure. The findings of this study do therefore not endorse a strong recommendation for or against any of the ergonomic devices commonly recommended for patients with CTS. Selection of ergonomic devices remains dependent on personal preference.

The impact of computer use in myopia progression: a cohort study in Spain

OBJECTIVE

Many subjects, especially highly educated subjects, are increasingly exposed to computer use. This exposure might represent an explanation for the growing rates of myopia.

METHODS

We assessed 17,217 Spanish university graduates from the SUN project, an open-recruitment cohort. Their mean age was 38.5 years (SD 12.1), and their mean time of exposure to computers was 14.3h/week (SD 14.6). We estimated multivariable-adjusted odds ratios (OR) for the risk of myopia development and/or progression (≥0.5 diopters) according to baseline exposure to computer and to changes in exposure.

RESULTS

The age and sex-adjusted OR comparing >40 h/week of exposure versus<10h/week was 1.34 (95% confidence interval (CI): 1.12-1.60). This association remained essentially unchanged after additional adjustments. Comparing participants who increased their exposure to computers, versus those with no change, the age and sex-adjusted OR was 1.49 (1.34-1.66). This result was unchanged after additional adjustments.

CONCLUSIONS

To our knowledge this is the first large longitudinal assessment in young adults, showing that exposure to computer use is associated with myopia development or progression in a cohort of Spanish university graduates. Further studies are needed to confirm these epidemiological findings.

Office workers' computer use patterns are associated with workplace stressors

This field study examined associations between workplace stressors and office workers' computer use patterns. We collected keyboard and mouse activities of 93 office workers (68F, 25M) for approximately two work weeks. Linear regression analyses examined the associations between self-reported effort, reward, overcommitment, and perceived stress and software-recorded computer use duration, number of short and long computer breaks, and pace of input device usage. Daily duration of computer use was, on average, 30 min longer for workers with high compared to low levels of overcommitment and perceived stress. The number of short computer breaks (30 s-5 min long) was approximately 20% lower for those with high compared to low effort and for those with low compared to high reward. These outcomes support the hypothesis that office workers' computer use patterns vary across individuals with different levels of workplace stressors.

Computerization and its contribution to care quality improvement: the nurses' perspective

BACKGROUND

Despite the widely held belief that the computerization of hospital medical systems contributes to improved patient care management, especially in the context of ordering medications and record keeping, extensive study of the attitudes of medical staff to computerization has found them to be negative. The views of nursing staff have been barely studied and so are unclear. The study reported here investigated the association between nurses' current computer use and skills, the extent of their involvement in quality control and improvement activities on the ward and their perception of the contribution of computerization to improving nursing care. The study was made in the context of a Joint Commission International Accreditation (JCIA) in a large tertiary medical center in Israel. The perception of the role of leadership commitment in the success of a quality initiative was also tested for.

METHODS

Two convenience samples were drawn from 33 clinical wards and units of the medical center. They were questioned at two time points, one before the JCIA and a second after JCIA completion. Of all nurses (N=489), 89 were paired to allow analysis of the study data in a before-and-after design. Thus, this study built three data sets: a pre-JCIA set, a post-JCIA set and a paired sample who completed the questionnaire both before and after JCIA. Data were collected by structured self-administered anonymous questionnaire.

RESULTS

After the JCIA the participants ranked the role of leadership in quality improvement, the extent of their own quality control activity, and the contribution of computers to quality improvement higher than before the JCIA. Significant Pearson correlations were found showing that the higher the rating given to quality improvement leadership the more nurses reported quality improvement activities undertaken by them and the higher nurses rated the impact of computerization on the quality of care. In a regression analysis quality improvement leadership and computer use/skills accounted for 30% of the variance in the perceived contribution of computerization to quality improvement.

CONCLUSIONS

(a) The present study is the first to show a relationship between organizational leadership and computer use by nurses for the purpose of improving clinical care. (b) The nurses' appreciation of the contribution computerization can make to data management and to clinical care quality improvement were both increased by the JCI accreditation process.

Computer vision syndrome and associated factors among medical and engineering students in chennai

Background:

Almost all institutions, colleges, universities and homes today were using computer regularly. Very little research has been carried out on Indian users especially among college students the effects of computer use on the eye and vision related problems.

Aim:

The aim of this study was to assess the prevalence of computer vision syndrome (CVS) among medical and engineering students and the factors associated with the same.

Subjects and Methods:

A cross-sectional study was conducted among medical and engineering college students of a University situated in the suburban area of Chennai. Students who used computer in the month preceding the date of study were included in the study. The participants were surveyed using pre-tested structured questionnaire.

Results:

Among engineering students, the prevalence of CVS was found to be 81.9% (176/215) while among medical students; it was found to be 78.6% (158/201). A significantly higher proportion of engineering students 40.9% (88/215) used computers for 4-6 h/day as compared to medical students 10% (20/201) (P < 0.001). The reported symptoms of CVS were higher among engineering students compared with medical students. Students who used computer for 4-6 h were at significantly higher risk of developing redness (OR = 1.2, 95% CI = 1.0-3.1,P = 0.04), burning sensation (OR = 2.1,95% CI = 1.3-3.1, P < 0.01) and dry eyes (OR = 1.8, 95% CI = 1.1-2.9, P = 0.02) compared to those who used computer for less than 4 h. Significant correlation was found between increased hours of computer use and the symptoms redness, burning sensation, blurred vision and dry eyes.

Conclusion:

The present study revealed that more than three-fourth of the students complained of any one of the symptoms of CVS while working on the computer.

Unobtrusive measurement of daily computer use to detect mild cognitive impairment

BACKGROUND

Mild disturbances of higher order activities of daily living are present in people diagnosed with mild cognitive impairment (MCI). These deficits may be difficult to detect among those still living independently. Unobtrusive continuous assessment of a complex activity such as home computer use may detect mild functional changes and identify MCI. We sought to determine whether long-term changes in remotely monitored computer use differ in persons with MCI in comparison with cognitively intact volunteers.

METHODS

Participants enrolled in a longitudinal cohort study of unobtrusive in-home technologies to detect cognitive and motor decline in independently living seniors were assessed for computer use (number of days with use, mean daily use, and coefficient of variation of use) measured by remotely monitoring computer session start and end times.

RESULTS

More than 230,000 computer sessions from 113 computer users (mean age, 85 years; 38 with MCI) were acquired during a mean of 36 months. In mixed-effects models, there was no difference in computer use at baseline between MCI and intact participants controlling for age, sex, education, race, and computer experience. However, over time, between MCI and intact participants, there was a significant decrease in number of days with use (P = .01), mean daily use (∼1% greater decrease/month; P = .009), and an increase in day-to-day use variability (P = .002).

CONCLUSIONS

Computer use change can be monitored unobtrusively and indicates individuals with MCI. With 79% of those 55 to 64 years old now online, this may be an ecologically valid and efficient approach to track subtle, clinically meaningful change with aging.

Television viewing, computer use and total screen time in Canadian youth

BACKGROUND

Research has linked excessive television viewing and computer use in children and adolescents to a variety of health and social problems. Current recommendations are that screen time in children and adolescents should be limited to no more than 2 h per day.

OBJECTIVE

To determine the percentage of Canadian youth meeting the screen time guideline recommendations.

METHODS

The representative study sample consisted of 6942 Canadian youth in grades 6 to 10 who participated in the 2001/2002 World Health Organization Health Behaviour in School-Aged Children survey.

RESULTS

Only 41% of girls and 34% of boys in grades 6 to 10 watched 2 h or less of television per day. Once the time of leisure computer use was included and total daily screen time was examined, only 18% of girls and 14% of boys met the guidelines. The prevalence of those meeting the screen time guidelines was higher in girls than boys.

CONCLUSION

Fewer than 20% of Canadian youth in grades 6 to 10 met the total screen time guidelines, suggesting that increased public health interventions are needed to reduce the number of leisure time hours that Canadian youth spend watching television and using the computer.
