Objective: The aim of this study was to conduct a detailed geospatial analysis of mobile phone signal coverage in the northwest macro-region of Paraná State, Brazil, seeking to identify areas where limitations in coverage may be related to lengthy travel times of the helicopter emergency medical service (HEMS) for the assistance of victims of road traffic injuries (RTIs). Methods: An observational study was conducted to examine mobile phone signal coverage and HEMS travel times from 2017 to 2021. HEMS travel times were categorized into four groups: T1 (0–15 min), T2 (16–30 min), T3 (31–45 min), and T4 (over 45 min). Empirical Bayesian Kriging was used to map areas with low mobile signal coverage. The Kruskal–Wallis test and Dwass–Steel–Critchlow–Fligner comparative analyses were performed to explore how mobile signal coverage relates to HEMS travel times to RTI locations. Results: There were 470 occurrences of RTIs attended by HEMS, of which 108 (23%) resulted in on-site fatalities. Among these deaths, 47 (26.85%) occurred in areas with low mobile phone signal coverage ("shadow areas"). Low mobile phone signal coverage identified at 175 (37.24%) RTIs locations, was unevenly distributed across the macro-region. The lowest medians of mobile signal quality were predominantly found in areas with HEMS travel times exceeding 30 min, corresponding to signal strength values of −98.44 (T3) and −100.75 (T4) dBm. This scenario represents a challenge for effective communication to activate HEMS. In the multiple comparison analysis among travel time groups, significant differences were observed between T1 and T2 (p < 0.001), T1 and T3 (p < 0.001), T1 and T4 (p < 0.001), and T2 and T3 (p < 0.001), indicating a potential association between lower mobile phone signal coverage and longer HEMS travel times. Conclusion: It can be concluded that poor mobile phone signals in remote areas can hinder HEMS activation, potentially delaying the start of treatment for RTIs. Identification of the shadow areas can help communication and health managers in designing and implementing the necessary changes to improve mobile phone signal coverage and consequently reduce delays in the initial response to RTIs.

Objective: Non-ionizing radiofrequency radiation, which finds application in various sectors such as industry, commerce, medicine, and particularly in mobile phone technology, has emerged as a topic of significant concern during pregnancy. The aim of this study was to investigate the effect of cell phone radio-frequency (RF) radiation during pregnancy on the Matrix metalloproteinase 2 (MMP-2) and (MMP-9) 9 expressions after neonatal hypoxia-ischemia (HI) in rats. Materials and methods: Two groups were formed by randomly assigning female Wistar rats: Group 1 consisted of female rats that were not exposed to RF radiation during pregnancy, while Group 2 comprised female rats that were exposed to RF radiation during pregnancy. After delivery, male offspring were divided into four groups including: (a) SHAM, (b) Exposure (EXP), (c) hypoxia-ischemia (HI), (d) HI/Exposure (HI/EXP). Seven days after HI induction, neurobehavioral tests were performed, and then brain tissue was taken from the skull to measure MMP-2 and MMP-9 expressions, inflammation, oxidative stress, infarct volume and cerebral edema. Results: MMP-9 mRNA expression in the HI/EXP group was significantly higher than the HI, SHAM and EXP groups. MMP-2 mRNA expression levels in the HI group were significantly higher than Sham and the EXP groups.TNF-α and Total oxidant capacity (TOC) levels in the HI/EXP group were significantly higher than HI, EXP and SHAM groups. Total antioxidant capacity (TAC) level in the HI/EXP group were significantly lower than HI, EXP and SHAM groups. Cerebral edema and infarct volume in the HI/EXP group were significantly greater than the HI group. Sensory-motor function was significantly weaker in HI/EXP as compared HI group. Conclusion: Our findings indicate that during pregnancy, exposure to mobile phone RF radiation intensifies damage from HI in rat pups by elevating MMP-9 activity.

Introduction: The increasing usage of smartphones across the globe has resulted in considerable changes in people's daily lives, especially in terms of personality traits among adults. Research shows that the Big Five personality traits influence Problematic Mobile Phone Use (PMPU). Aim: To estimate the prevalence of PMPU using the Mobile Phone Problem Use Scale (MPPUS-10) and to evaluate the personality predictors of PMPU using the Big Five Inventory (BFI) questionnaire. Materials and Methods: A cross-sectional survey was conducted among 289 medical students at a rural tertiary care centre in Tamil Nadu, India from November 2021 to April 2022. The questionnaire consisted of three sections. The first section collected demographic characteristics, the second section included questions on the MPPUS-10, and the third section contained questions from the BFI questionnaire.

A multiple linear regression model was applied to determine the relationship between PMPU and the personality domains. Results: The prevalence of PMPU among medical students was found to be 106 (36.7%). Spearman's rank correlation revealed a negative correlation between agreeableness personality (r=-0.307, p-value <0.001) and conscientiousness personality (r=-0.369, p-value <0.001) with PMPU. Additionally, a positive correlation was observed between neurotic personality and PMPU (r=0.325, p-value <0.001). Multiple linear regression analysis demonstrated that agreeableness, conscientiousness, and neuroticism significantly predicted 44.4% of the scores on the PMPU (F=23.276, p-value <0.001 at the 1% level). Therefore, individuals with lower levels of agreeableness, conscientiousness, and higher levels of neuroticism scored higher on the MPPUS-10 scale. Conclusion: The prevalence of PMPU among medical students was found to be high, requiring attention. Individuals with lower levels of agreeableness and conscientiousness, as well as higher levels of neuroticism, were more likely to exhibit PMPU. [ABSTRACT FROM AUTHOR]

BackgroundHIV/AIDS is now a manageable chronic illness owing to effective antiretroviral therapy (ART), which involves routine follow-up care, including regular physical visits to the clinic. In the recent past, and in wake of the COVID-19 pandemic, there has been increased need for virtual care and intervention delivery, a modality known as mobile health (mHealth), which includes cell phone-delivered services for medical and public health practice.ObjectiveHere we describe cell phone use and its relationship with alcohol use in a cohort of persons living with HIV and latent tuberculosis (TB).MethodsWe performed a cross-sectional analysis of baseline data from a cohort of persons living with HIV and latent TB in HIV care in southwestern Uganda. We estimated proportions of cell phone and text message use and evaluated their associations with alcohol use-a common modifiable behavior among persons living with HIV. Cell phone use (primary outcome) was defined as owning a cell phone that is turned on at least half of the day. Any alcohol use was defined as any self-reported alcohol use in the prior 3 months or a phosphatidylethanol (an alcohol biomarker) level of ≥8 ng/mL.ResultsA total of 300 participants (median age 40 years; n=146, 48.7% male) were included in the analysis. Most (n=267, 89.0%) participants had access to a phone and of them, 26 (9.7%) shared the phone with someone else. In total, 262/300 (87.3%) of participants owned a cell phone that is turned on at least half of the time; the majority (n=269, 89.7%) rarely or never sent text messages, and over two-thirds (n=200, 66.9%) rarely or never received text messages. Most (n=214, 71.3%) had any alcohol use in the prior 3 months. In adjusted analyses, any alcohol use was not significantly associated with cell phone use (adjusted odds ratio [aOR] 0.48, 95% CI 0.18-1.25; P=.13) or sending (aOR 0.82, 95% CI 0.28-2.37; P=.71) or receiving (aOR 1.31, 95% CI 0.70-2.47; P=.40) text messages.ConclusionsThere is hope that mHealth interventions in this population can be carried out using cell phones owing to their popularity; however, the interventions may need to employ methods that do not rely on the sending and receiving of text messages only.

• Oil and gas extraction workers self-reported risky driving behaviors, including using cell phones while driving, speeding, and not always wearing a seat belt. • Longer work hours, longer daily commutes, lack of employer policies, and crash history associated with greater risk of certain risky driving behaviors. • Oil and gas extraction employers could implement cell phone bans, measures to reduce speeding, and in-vehicle monitoring systems to promote safe driving. Introduction : Over half of fatal occupational injuries in the oil and gas extraction (OGE) industry are due to transportation incidents. While driving for work is common in this industry and risky driving behaviors have been identified as contributing factors to fatal crashes among OGE workers, limited information is available on the frequency of risky driving behaviors and employer policies to reduce these behaviors. Methods: Researchers conducted a cross-sectional survey of OGE workers in three states. Responses from 363 OGE workers who drive as a part of their work duties were analyzed to evaluate relationships between self-reported risky driving behaviors (i.e., speeding, cell phone use, and driving unbelted) and awareness of motor vehicle safety policies by their employers. Results : Hands-free cell phone use was the most common risky driving behavior among participants (59.8%), while a hands-free cell phone ban was the least commonly reported employer motor vehicle safety policy (34.7%). Multiple logistic regression results identified longer work and commuting hours, lack of employer motor vehicle safety policies, having ever been in a work crash, and being employed by an operator to be significantly associated with risky driving behaviors. Conclusions: Workers whose employers lacked motor vehicle safety policies were more likely to engage in risky driving behaviors. Practical applications: Results of this survey support the implementation of motor vehicle safety interventions such as bans on texting and handheld and hands-free cell phone use, speed management, and in-vehicle monitoring systems by OGE employers as well as research focusing on the effectiveness of these interventions in OGE. Additional research could examine worker driving behaviors through self-reported data in combination with objective measures. [ABSTRACT FROM AUTHOR]

Objectives: To estimate the impact of intervention through telephone social networks in improving Pap smearscreening in districts of the Lambayeque region. Material an metodos: Intervention study, two districts (intervention and control) were randomly selected for each province of the Lambayeque region, using Epidat 3.1 231 people were obtained: 115 intervention group and 116 control group; Inclusion criteria: Women aged 30 to 50 living in the six selected districts, who have a cell phone and can read text messages or WhatsApp. Instruments: survey validated by experts applied by two pollsters, messaging sent by specific personnel, supervision by field doctor. It was authorized by the Research Ethics Committee of the UCV and informed consent was applied. Results: The knowledge that both study groups had regarding the Pap test was quite good, however 83% of the total had no knowledge about the IVAA. After 2 months we returned to inquire if they had performed their Pap smear and it was found that in the intervened group on average only 25% had complied; Among the reasons why they had not been carried out, 44% "did not have time", a new reason was that "he was not in his district" 16%. In the control group, only 19% performed it. There is no statistically significant difference between the two groups with respect to post-intervention screening. Conclusions: Despite having sent messages to the cell phone, there was no statistical difference with those who did not receive it for new PAP screenings. [ABSTRACT FROM AUTHOR]

Adolescents' cell phone use occurs during significant developmental shifts in parent–adolescent relationships, as adolescents' drives for independence can conflict with parents' desires for connection. This study examines parental mediation of cell phone use within an interpersonal and family communication framework. Previous mediation research has not examined connections with social penetration theory, uncertainty reduction theory, relational dialectics theory, and communication privacy management, each of which has conceptual links to parental mediation. Cell phone mediation reflects the broader phenomenon of disclosure in interpersonal relationships. The extent to which individuals disclose information is influenced by personal desires for autonomy and connection, privacy and intimacy, which are components of interpersonal and family communication theories. This study explores the notion that families develop norms and expectations about cell phones that might influence parental mediation. Results indicate that perceptions of parent–child relationships and family expectations for cell phone use both significantly influence mediation. [ABSTRACT FROM AUTHOR]

Background: Within few years, there is a quick increase in ratios showing more than quarter of Pakistani adults is obese which is a serious concern to their health. This obesity is often associated with increased usage of screen such as mobile, TV and computers. The objective of the study was to assess the association between screen-time and obesity co-relating with factors such as snack and fizzy drink uptake, exercise and mental health. Methods: A cross-sectional study was performed on 257 participants of Karachi, Pakistan, aged 5 to 60 years from both genders. A questionnaire was filled asking about their screen usage, eating habits, exercise routine and BMI. The data was analyzed by using Student T test & ANOVA to assess the significance of obesity with screen-time and other often associated factors. Results: On statistical analysis, the results showed that the P- value between obese and non-obese group for screen-time was p=0.557 in females and p=0.488 in males respectively. Similarly, P-value for eating habits and physical activity between the obese and non-obese group were insignificant. Conclusion: Based on the given statistical data increase in screen-time lacks direct and indirect association with obesity and its risk factors. Hence further research needs to be conducted to find a scientific co-relation between the two factors. [ABSTRACT FROM AUTHOR]

Background: Sedentary behavior (SB) is considered a risk factor for musculoskeletal pain. We aimed to explore the association of sedentary behavior indicators with neck pain among children and adolescents. Methods: A comprehensive review was performed in different databases until the end of January 2022. Odds ratios (ORs) with 95% confidence intervals were used as desired effect sizes to evaluate the association between prolonged screen time or mobile phone (MP) usage and neck pain risk. Results: Among 1651 records, 15 cross-sectional studies were included in the systematic review, and 7 reports were included in the meta-analysis. Our results suggested a significant relationship between prolonged MP use and neck pain (OR=1.36, 95% CI=1.001–1.85, I2=40.8%, P value for heterogeneity test=0.119). Furthermore, a marginally insignificant association was found between prolonged screen time and neck pain (OR=1.13, 95% CI=0.98–1.30, I2=60.3%, P value=0.01); however, after sensitivity analysis and removing one study, this association became significant (OR=1.30, 95% CI=1.03–1.64). Moreover, a significant association between prolonged sitting time and neck pain was reported in two studies. Conclusion: Available good-quality evidence reveals a significant mild association between sedentary behavior and the risk of neck pain among children and adolescents. However, longitudinal studies with objective measurement tools are warranted. In particular, potential preventive educational programs are suggested for pediatrics to reduce sedentary behavior and neck pain.

INTRODUCTION:Cervical cancer prevention is possible through use of the HPV vaccine and Pap tests, yet the vaccine remains underutilized. METHODS:We obtained publicly-available Twitter data from 2014 using three sampling strategies (top-ranked, simple random sample, and topic model) based on key words related to cervical cancer prevention. We conducted a content analysis of 100 tweets from each of the three samples and examined the extent to which the narratives and frequency of themes differed across samples. RESULTS:Advocacy-related tweets constituted the most prevalent theme to emerge across all three sample types, and were most frequently found in the top-ranked sample. A random sample detected the same themes as topic modeling, but the relative frequency of themes identified from topic modeling fell in-between top-ranked and random samples. DISCUSSION:Variations in themes uncovered by different sampling methods suggest it is useful to qualitatively assess the relative frequency of themes to better understand the breadth and depth of social media conversations about health. CONCLUSIONS:Future studies using social media data should consider sampling methods to uncover a wider breadth of conversations about health on social media.

Objective: To inquire about the relationship between the appropriation and use of virtual social networks and the construction of self in school teenagers. Materials and methods: Qualitative study led by the guidelines of the grounded theory and the approach of symbolic interactionism. The study was carried out in the years 2016-2017 with 19 tenth grade students of a municipality in the east near Medellin, Colombia. Data collection was carried out through semi-structured interviews and focus groups. Results: The construction of identity in these adolescents occurs in interactions with their families, friends and interest groups, and mediated by virtual social networks. These social networks satisfy their information, knowledge, communication and entertainment needs, and reflect on the opportunities and threats associated with their use. Conclusion: Teenagers have an active attitude towards life and the appropriation and use of virtual social networks for interactions with others and, the search for information that satisfies their interests, opens a window to the world for them [ABSTRACT FROM AUTHOR]

Cell phone use (CPU) impacts the sleep quality, academic performance, and psychological wellbeing (PWB) of young adults. A strong theoretical framework was warranted to explain these impacts. Also, the theoretical framework was warranted to understand the inter-variable interactions for sleep quality, academic performance, and PWB, and their impact on the mental health of young adults. The presented study provides a research-based theoretical framework for CPU-led sleep quality, academic performance, and PWB, which is built on existing developmental theories. The developmental theories are grouped under four overarching theories, which are nested under the bigger umbrella of cognitivism. The framework offers a theoretical explanation for all three CPU-led mechanisms associated with sleep quality, academic performance, and PWB. The Sleep Displacement Theory and Arousal Theory explains CPU-led sleep disruption. The Switch Load Theory and Self-regulated Learning Theory explains CPU multitasking and self-regulated learning behavior. The Six-factor Model of Psychological Well-Being and Maslow's Hierarchy of Psychological Needs explains CPU-led PWB. The presented framework will help explore CPU-led sleep quality, academic performance, and PWB from a theoretical perspective, hence, will help provide theoretical support to the empirical finding relating to these variables. The significance of the theoretical framework in all three domains and the practical implications of the findings to the real world are discussed. [ABSTRACT FROM AUTHOR]

Background The educational component is a comprehensive part of Pulmonary Rehabilitation (PR), and telephone follow-up (TFU) is an alternative to reinforce face-to-face education. The objective was to determine the effect of telephone follow-up on educational needs, dyspnea, quality of life and functional capacity in Chronic Obstructive Pulmonary Disease (COPD) patients undergoing PR. Methods Double-blind randomized controlled clinical trial in patients with COPD in a PR program in Cali-Colombia, allocation by randomization tables. All patients received 24 sessions of PR, which included face-to-face education sessions. In addition, the experimental group received telephone calls twice a week to reinforce the face-to-face educational content. The Lung Information Needs Questionnaire (LINO) was used to measure disease knowledge, the Saint George's Respiratory Questionnaire to measure quality of life, the modified Medical Research Council (mMRC) scale to measure dyspnea, and the 6-minute walking test (6MWT) to measure functional capacity. Results Thirty-four patients were randomized and 31 were analyzed. PR group with conventional education (PRTE) n=15 and PR group with education plus telephone follow-up (PRTETFU) n=16. Significant improvement from baseline to endpoint in both groups: LINO (PRTE 4±1.1, p=0.003, PRTETFU 5.8±10.6, p=0.000), mMRC (PRTE 1.6±0.3, p=0.000, PRTETFU 0.6±0.3, p=0.036) and functional capacity (PM6M: PRTE 45.9m±16.1, p=0.013, PRTETFU 62.8m±21.4, p=0.010). Analysis showed differences between groups for changes in LINQ knowledge domain after intervention, with greater improvement for PRTETFU (p=0.018). Discussion The TFU is an alternative to reinforce the education. This study demonstrated greater positive effects for the autonomous management of the pathology. Conclusion Adding educational reinforcement through phone calls to patients with COPD during PR leads to improved knowledge and skills for managing the disease. [ABSTRACT FROM AUTHOR]

The study focused on explaining the association between relationship appraisal and couple conflicts due to cell phone use, considering a sample of 325 couples between 18 and 65 years of age. For this purpose, the Relationship Appraisal Scale (RAS) and the scale of conflicts related to cell phone use were administered. The study was framed within the basic research paradigm, with a non-experimental, correlational and cross-sectional design. It was obtained as a result that the valuation of the relationship is negatively, moderately and significantly associated (rs= -,456, p<,05) with couple conflicts due to cell phone use. It was evidenced that couples perceive a positive and negative valuation for the use of the cell phone; that is, the valuation of the relationship and the use of the cell phone would generate conflicts and benefits in the couples. The inappropriate or appropriate use of mobile devices could have effects on the relationship between couples. In this sense, it can be concluded that the good use of the cell phone can help satisfaction, efficient communication and maintain a permanent bond through the various applications between couples. On the other hand, inappropriate use can generate problems, conflicts of interest, low satisfaction, disinterest and even separations. The cell phone, as a mobile device, could help in the valuation of the relationship or generate conflicts in the couple depending on its use. [ABSTRACT FROM AUTHOR]

The interaction effect between time of day and distractions on driving was verified. Distracted drivers had greater SDLP at night than during daytime on some roads. The speed under the phone distractions was higher at night on small-radius curves. In daytime, SDLP during talking was less than under no distraction in some scenarios. Novice drivers had higher driving speed than experienced drivers under talking. Currently, young drivers are more likely than other drivers to use cell phones while driving at night, which has become a major cause of road crashes. However, limited attention has been given to distracted nighttime driving. Therefore, the aim of this study was to explore the interaction effect of cell phone use and time of day (daytime and nighttime) on young drivers' car-following performance. Forty-three young drivers engaged in a driving simulator experiment with a within-subject design that included three distractions (no distraction, talking and texting on a cell phone) and two times of day. This paper applied non-parametric tests to analyze the data and obtained the following results: (1) the standard deviation of lane position (SDLP) did not significantly differ at either time of day under no distraction, but it was significantly higher at night on straight roads and large-radius curves after introducing distractions. In addition, participants drove faster and gave less headway on small-radius curves under both distractions at night; (2) texting significantly increased the SDLP, while there was less lateral variation during the talking tasks than under no distraction on simple road sections; and (3) compared with the experienced drivers, the novice drivers drove faster during the talking tasks on small-radius curves, but there was no significant difference between groups during the texting tasks. These findings provide both theoretical and practical implications for related policy makers to enhance traffic safety. [ABSTRACT FROM AUTHOR]

BACKGROUND: Adolescents are described as digital natives, with smartphones deeply embedded in their lives. However, limited literature on smartphone usage patterns exists. This study examined adolescents' smartphone usage patterns and their physical, psychosocial, and cyber‐behavioral profiles. METHODS: We used latent profile analysis and a person‐centered approach to investigate 11 items on smartphone use purpose and use time. Participants were 2324 first‐year middle‐school students (aged 13 years) from a nationally representative dataset. RESULTS: Four distinct profile groups were observed: minimalist users, entertainment users, social users, and multifunctional users. The 4 profiles differed by gender and physical (physical activity and obesity), psychosocial (relationships with their parents, depression, and academic lethargy), and cyber‐behavioral (smartphone use time, computer use time, and cyber delinquency) status. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Our findings have key research and real‐world implications for developmental psychologists and school health providers, specifically for those who work with adolescents, to address concerns regarding adolescents' smartphone use. CONCLUSIONS: Adolescents use smartphones at varying times and for various purposes. A better understanding of adolescents' smartphone usage and purposes can help parents and school health providers develop and implement interventions. [ABSTRACT FROM AUTHOR]

Background: Academic underachievement is a growing phenomenon among medical students, influenced by several factors.Objectives: This study investigated the relationship between academic underachievement and problematic cell phone use among medical students at Kerman University of Medical Sciences.Methods: This cross-sectional study was conducted on 300 medical students at KUMS during the academic year 2019. The Persian version of Problematic Cellular Phone Use Questionnaire was used for data collection. Also, the demographic data of the students were recorded, and they were asked to declare if they had a history of academic underachievement in the previous year. Data were analyzed by SPSS software version 20.0 using Chi-square test and logistic regression.Results: The mean age of medical students was 22.41±2.6 years, and the majority (74.3 %) of them were female. The chance of academic underachievement was 6.37 times higher in medical students who have problematic cellular phone use compared to those without it (OR=6.37, P=0.001). Also, this chance was 4.45 times higher in medical students who had a history of psychological disorders compared to those without (OR=4.45, P=0.02).Conclusion: The current study revealed that the chance of academic underachievement was higher in medical students with problematic cellular phone use and a history of psychological disorders. Given that academic underachievement is not uncommon, its related factors must be appropriately identified and intervened on time.

Background: In China, undergraduate students face both academic and career selection pressures, sleep is an important physiological process for them. Investigate the physical exercise, sleep quality of undergraduate students in the education stage in Xuzhou City, and analyze the factors affecting their sleep quality, to promote the health education and psychological health of undergraduate students. Materials and methods: The Physical Activity Rating Scale-3 (PARS-3), the Pittsburgh Sleep Quality Index (PSQI), and the demographic information questionnaire were used to survey a whole-group sample of four undergraduate colleges and universities (Xuzhou Institute of Engineering, Xuzhou Medical University, China University of Mining and Technology, Jiangsu Normal University) in Xuzhou by cluster sampling, the general characteristics including gender, grade, height, weight, domicile, race, economic income, etc., were collected, and the data were analyzed and processed using chi-square tests and multi-factor logistic regression. Results: 3,366 valid questionnaires were collected from four undergraduate colleges and universities, including 1,355 males and 2,011 females. The detection rate of exercise in Jiangsu Normal University was lower than that in other universities, and the detection rate of sleep disorders was higher than that in other universities. Xuzhou Medical University, the highest detection rate of large exercise, Xuzhou Institute of Technology, the lowest detection rate of sleep disorders. There were significant differences in the detection rate of large amount of exercise among college students of different genders, grades, body types, and majors (χ² = 259.172, P < 0.001; χ² = 34.473, P < 0.001; χ² = 36.026, P < 0.001; χ² = 57.908, P < 0.001). There were significant differences in the detection rate of sleep disorders among college students with different gender, grade, family economic status, daily cell phone use time, cell phone purposeless usage, and exercise level (χ² = 5.806, P = 0.016; χ² = 47.5, P < 0.001; χ² = 28.949, P < 0.001; χ² = 55.866, P < 0.001; χ² = 147.101, P < 0.001; χ² = 9.129, P = 0.010). Multivariate logistic regression analysis showed that grade, family economic status, cell phone use time, cell phone purposeless usage is the main influencing factors of sleep disorders in college students. Conclusion: The sleep problems of undergraduates are serious, especially in Jiangsu Normal University. Scientific and appropriate exercise is an important measure to solve the sleep problems of undergraduates. Colleges and universities should actively carry out health education, college students living habits such as cell phone use should be guided training. [ABSTRACT FROM AUTHOR]

Child externalising problems, such as acting out and hostility, have been found to be significant stressors for parents, leading to increased distress levels. This cross-sectional study examined the mediating role of parents' use of mobile phones to soothe or engage children in the association between child externalising problems and distress in parents. Altogether 937 parents of children aged 5-12 reported their child's externalising problems, child's mobile phone use, and their distress through an online survey. The findings indicated that parents of children with high externalising problems are more likely to use mobile phones to soothe their children and keep them engaged in daily activities, which, in turn, is associated with higher distress in parents. Child externalising problems and distress in parents remained significantly and positively associated even after accounting for the mediating effect. The results highlight the child-driven effect on distress in parents through parenting behaviours, indicating the importance of providing alternative parenting strategies to cope with child externalising behaviours, in order to promote parental emotional well-being., (© 2024 John Wiley & Sons Ltd.)

Aim: This research aimed to determine the impact of problematic mobile phone use on negative mental health outcomes among nursing students in India, highlighting the necessity for targeted interventions and support mechanisms to enhance the overall well-being and adaptability of future healthcare professionals., Methods: A cross-sectional survey was conducted in three randomly selected nursing colleges in South India, employing validated and standardized tools such as the Mobile Phone Problematic Use Scale, Patient Health Questionnaire, Insomnia Severity Index Scale, Satisfaction with Life Scale and Rosenberg Self-Esteem Scale., Results: The study included 402 nursing students with an average age of 20.47 years, revealing a 39% prevalence of severe problematic mobile phone usage. Positive correlations were observed between mobile phone problematic use and age, depression and insomnia. Additionally, strong negative correlations were found between satisfaction with life and self-esteem. Depression and satisfaction with life served as chain mediators in the impact of self-esteem on problematic mobile phone use, and both self-esteem and satisfaction with life negatively predicted problematic mobile phone use., Conclusion: The study highlights a prevalent issue of problematic mobile phone use among nursing students, indicating a pressing need for timely intervention, as it correlates with depression, sleep insomnia, low self-esteem and life dissatisfaction., (© 2024 John Wiley & Sons Australia, Ltd.)

Our results suggested a significant relationship between prolonged MP use and neck pain (OR = 1.36, 95% CI = 1.001-1.85, I2 = 40.8%, P value for heterogeneity test = 0.119). Furthermore, a marginally insignificant association was found between prolonged screen time and neck pain (OR = 1.13, 95% CI = 0.98-1.30, I2 = 60.3%, P value = 0.01); however, after sensitivity analysis and removing one study, this association became significant (OR = 1.30, 95% CI = 1.03-1.64). Moreover, a significant association between prolonged sitting time and neck pain was reported in two studies. Conclusion: Available good-quality evidence reveals a significant mild association between sedentary behavior and the risk of neck pain among children and adolescents. However, longitudinal studies with objective measurement tools are warranted. In particular, potential preventive educational programs are suggested for pediatrics to reduce sedentary behavior and neck pain. [ABSTRACT FROM AUTHOR]

Motor vehicle crashes are a leading cause of death in the United States. Further, cigarette smoking is associated with negative health and work outcomes. However, scant research on data for the United States has analyzed the association between cigarette smoking rates and motor vehicle death rates. This study fills that void. It estimates the association via ordinary least squares regression on annual state-level data for 2011–2019, controlling for other known factors related to motor vehicle death rates and accounting for year and region fixed effects. Results indicate that the cigarette smoking rates of a state's population are significantly and directly related to the motor vehicle fatality rates in that state. Further, interaction results indicate that alcohol consumption's positive association with motor vehicle fatalities is highest in states with more smokers. The findings suggest that smokers may be more likely to die in motor vehicle crashes than non-smokers, and that driver safety programs targeting smokers warrant funding. [ABSTRACT FROM AUTHOR]

Purpose: Traffic accidents are one of the major health problems in the world, being the first cause of burden of illness and the second leading cause of death in Iran. The Sistan-Baluchestan province is one of the most accidental provinces of Iran with the highest rate of accidents-caused deaths. This study was conducted to determine the risk factors associated with traffic accidents in Zahedan through 2013 to 2016. Methods: This analytical cross-sectional study was carried out on 223 drivers from Zahedan who were traumatized by traffic accident and sent to Zahedan hospitals. The data were obtained through interviews taken by the trained interviewers via refereeing to the medical records and collected in the researcher-made checklist. Census was obtained from the study subjects. For data analysis, independent t-test, one-way ANOVA, Chi-square and logistic regression were used with the Stata software version 11.0. Results: In this study, 223 male subjects with the mean age of (32.54 ± 12.95) years, 39.8% single and 60.2% married, entered for investigation. Most accidents (38.8%) occurred between 12:00 to 17:59. While driving, 47.1% of the study subjects were using cell phones, 89.1% had manual use of mobile phones, 21.9% had a habit of sending short message service (SMS) and 23.4% had sent SMS within 10 min before the accident. The one way analysis of variance showed that the mean age of individuals with marital status, driving experience, education and accident with motorcycle were significantly different (p

Background: The association between problematic mobile phone use (PMPU) and negative emotions in university students is not well understood in terms of causality and directionality. This study aims to clarify whether negative emotions trigger PMPU or whether the PMPU itself leads to increased negative emotions over time., Methods: A two-wave longitudinal study was conducted involving 5568 Chinese freshmen who were surveyed at baseline and followed up after one academic year. PMPU, social media use, online game use, fear of missing out, loneliness, social anxiety, and academic burnout were measured. Cross-sectional and longitudinal connections between these variables were examined using network analysis techniques., Results: The variable with the strongest influence in both contemporaneous networks was "Productivity loss" of MAPI. Moreover, "Academic burnout" at baseline significantly predicted higher levels of problematic smartphone use and negative emotions at follow-up, suggesting that it may serve as a catalyst for addictive tendencies. Furthermore, we observed bidirectional relationships between "Escapism" and "Social anxiety", as well as between "Social anxiety" and "Inability to control craving", suggesting a potential self-perpetuating cycle., Conclusion: These findings highlight the role of academic burnout in initiating cycles of PMPU and negative emotions. In order to effectively tackle PMPU, it is crucial to consider the underlying drivers such as academic burnout and emotional states. This is important due to the complex and reciprocal associations uncovered through our longitudinal network analysis., Competing Interests: Declaration of competing interest The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 The Author(s).

Objectives: The aim of the study was to compare three color parameters assessed on the maxillary right central incisors using a spectrophotometer as the gold standard, along with RAW mobile calibrated and non-calibrated photos in different light conditions. Materials and methods: A total of 30 dental students participated in the study. CIE L*a*b* values were measured in the middle third of each maxillary right central incisor spectrophotometrically and digitally on RAW mobile dental photos using different light conditions (F-frontal light; L-lateral light; D-lateral light with diffusers; P- polarizing filter on frontal light; H-hybrid filter as combination of frontal light with polarizing filter and lateral lights with diffusers) with LEDs (light emitting diode) in full power, and with gray card calibration. The obtained results were compared. Results: Mean a* and b* values on calibrated, as well as mean L* values on non-calibrated RAW mobile photos did not significantly differ in different light conditions (P>0.05). CIE L*a*b* values on non-calibrated polarizing RAW mobile photos completely matched the same values obtained using a spectrophotometer on the subject’s maxillary right central incisor (P>0.05). Conclusions: Different light conditions and measuring procedures affected CIE L*a*b* values on RAW mobile photos in this study. Within the limitations, non-calibrated RAW mobile photos using a lightening device with polarizing filters on frontal LED light in standardized conditions can be a useful tool for digital dental shade determination.

Abstract Background The wide scale and severity of consequences of tobacco use, benefits derived from cessation, low rates of intervention by healthcare professionals, and new opportunities stemming from novel communications technologies are the main factors motivating this project. Thus, the purpose of this study is to assess the effectiveness of an intervention that helps people cease smoking and increase their nicotine abstinence rates in the long term via a chat-bot, compared to usual practice, utilizing a chemical validation at 6 months. Methods Design: Randomized, controlled, multicentric, pragmatic clinical trial, with a 6-month follow-up. Setting: Healthcare centers in the public healthcare system of the Community of Madrid (Madrid Regional Health Service). Participants: Smokers > 18 years of age who attend a healthcare center and accept help to quit smoking in the following month. N = 460 smokers (230 per arm) who will be recruited prior to randomization. Intervention group: use of a chat-bot with evidence-based contents to help quit smoking. Control group: Usual treatment (according to the protocol for tobacco cessation by the Madrid Regional Health Service Main variable: Continuous nicotine withdrawal with chemical validation (carbon monoxide in exhaled air). Intention-to-treat analysis. Difference between groups in continuous abstinence rates at 6 months with their corresponding 95% confidence interval. A logistic regression model will be built to adjust for confounding factors. Results: First expected results in January 2020. Discussion Providing science-based evidence on the effectiveness of clinical interventions via information technologies, without the physical presence of a professional, is essential. In addition to being more efficient, the characteristics of these interventions can improve effectiveness, accessibility, and adherence to treatment. From an ethics perspective, this new type of intervention must be backed by scientific evidence to circumvent pressures from the market or particular interests, improve patient safety, and follow the standards of correct practices for clinical interventions. Trial registration ClinicalTrials.gov, reference number NCT 03445507.

Background and Objectives: During the past decade, a growing number of studies separately and in different populations have examined cell phone addiction. Present study examines the relationship of psychological well-being and mental health in explaining cell phone addiction among adolescent students. Material and Methods: This was a descriptive-correlational study. The participants of the study were 300 students (162 boys and 138 girls) from secondary schools of Ahvaz who were selected by random multi-stage cluster sampling. In order to collect information, psychological well-being scale, mental health and cell phone addiction questionnaire were used. Pearson correlation coefficient and multiple linear regression analysis were applied to analyze the data using SPSS software. Results: The results showed that overall psychological well-being and all its dimensions negatively predict cell phone addiction. In addition, overall mental health and three subscales of anxiety and insomnia, social function, and depression were positive predictors of cell phone addiction. However, the subscale of physical symptoms was not a significant predictor of cell phone addiction. Conclusion: The above findings show that the utility of technology cannot be challenged, but to prevent addictive use of cell phones, paying more attention to adolescents in lower education courses and using mental health education are essential to promote psychological well-being and mental health and proper and effective use of cell phones among schools.

Objective: The present study aimed to evaluate the efficacy of a mindfulness-based cognitive therapy (MBCT) intervention in reducing problematic mobile phone use, depression, and sleep disorders among adolescents. Additionally, it sought to investigate whether the decrease in problematic mobile phone use acted as a mediator in the relationship between the MBCT intervention and adolescent depression and sleep disorders., Methods: In a randomized controlled trial, a total of 104 adolescents were randomly assigned to the mindfulness group (n = 52) or the wait-list control group (n = 52). The mindfulness group students completed eight 45-min sessions of mindfulness training in four weeks. The outcomes were measured at baseline, postintervention, and at the 2-month follow-up., Results: Compared with the control group, the mindfulness group had significantly greater levels of mindfulness and lower levels of problematic mobile phone use, depression, and sleep disorders postintervention. The intervention effects were maintained at the 2-month follow-up. In addition, decreased problematic mobile phone use significantly mediated the association between the MBCT intervention and decreased depression and decreased sleep disorders., Conclusion: The findings suggest that MBCT could improve adolescent depression and sleep disorders and that decreasing problematic mobile phone use is an effective pathway accounting for the MBCT intervention effect on adolescent depression and sleep disorders.

Introduction: Whereas parents play an important role in shaping the home environment, it is unknown whether health-related parent-adolescent conversations may be associated with different health-promoting parenting practices, such as limiting adolescent mealtime media use in Hispanic families., Method: For this cross-sectional analysis, Hispanic parents (n = 344; 40.4 ± 6.6 years; 89.2% female) of sixth- to eighth-grade adolescents self-reported the frequency of having health- or weight-related conversations with their adolescent child, and the frequency of adolescent mealtime media device use. Spearman's rank correlations were used to assess whether parent-adolescent health-related conversations are associated with mealtime media device use by adolescents., Results: Over 75% of parents reported having conversations about healthy eating and being physically active at least a few times per week. Fewer parents reported having frequent weight-related conversations. Frequency of mealtime media use was low, except for television/movie watching (only 30% of parents reported their child rarely/never watching television during family meals). Having conversations related to the adolescent weighing too much was correlated with the mealtime use of television ( r = .207; p < .001), cellphones ( r = .134; p = .018), and headphones for music listening ( r = .145; p = .010). Conversations about exercising to lose weight were correlated with television/movie watching during mealtimes ( r = .129; p = .035)., Discussion: Findings suggest the co-occurrence of less health-promoting parenting behaviors, such as focusing on weight-related conversations and allowing the use of media devices during mealtimes. Focusing on health- rather than weight-related parent-adolescent conversations and implementing mealtime media use rules may have the potential to shape a home food environment which ultimately could improve an adolescent's overall health outcomes.

The aim of this study was to investigate the relationships among aging self-stereotype, sense of coherence (SOC), and social isolation, as well as further explore the moderating role of cellphone use in older adults. The 817 Chinese older adults were assessed with regard to aging self-stereotypes, social isolation, SOC and cellphone use. Results from mediation analyses revealed that the negative effect of aging self-stereotype on social isolation was mediated by SOC. Moderated mediation analyses further indicated that the path from SOC to social isolation was stronger and the path from aging self-stereotype to social isolation was weaker for older adults with a higher level of cellphone use. These findings indicated that negative stereotypes were related to weaker SOC and are associated with more severe social isolation. Frequent use of cellphones can alleviate the negative effect of aging self-stereotype on social isolation and enhance the positive effect of SOC on social isolation., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Headache is a common condition with a substantial burden of disease worldwide. Concerns have been raised over the potential impact of long-term mobile phone use on headache due to radiofrequency electromagnetic fields (RF-EMFs). We explored prospectively the association between mobile phone use at baseline (2009-2012) and headache at follow-up (2015-2018) by analysing pooled data consisting of the Dutch and UK cohorts of the Cohort Study of Mobile Phone Use and Health (COSMOS) (N = 78,437). Frequency of headache, migraine, and information on mobile phone use, including use of hands-free devices and frequency of texting, were self-reported. We collected objective operator data to obtain regression calibrated estimates of voice call duration. In the model mutually adjusted for call-time and text messaging, participants in the high category of call-time showed an adjusted odds ratio (OR) of 1.04 (95 % CI: 0.94-1.15), with no clear trend of reporting headache with increasing call-time. However, we found an increased risk of weekly headache (OR = 1.40, 95 % CI: 1.25-1.56) in the high category of text messaging, with a clear increase in reporting headache with increasing texting. Due to the negligible exposure to RF-EMFs from texting, our results suggest that mechanisms other than RF-EMFs are responsible for the increased risk of headache that we found among mobile phone users., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Issue addressed: Caregivers have a crucial role to play in keeping children safe at public swimming pool facilities, with the most common factor contributing to childhood drowning being a lapse in adult supervision. Methods: A mixed methods approach was used to collect observations (n = 301) and interviews (n = 10) with caregivers of children aged 0‐10 years at two public swimming pool facilities located in the Perth metropolitan area, Western Australia (WA). Results: Of the 449 children observed, children aged 6‐10 years were significantly less likely to be provided with ideal supervision (26%) compared to younger children aged 0‐5 years (62%). Of the caregivers who were using their mobile phone while supervising children (n = 100, 22% of children observed), none provided ideal supervision. Overall supervision levels among caregivers differed with gender, with only 44% (n = 74) of female caregivers providing ideal supervision, compared to 72% (n = 96) of male caregivers. The 10 interviews revealed several themes, including the following: caregivers' perceptions of their supervision responsibilities; barriers to supervision; and awareness and perceptions of a communications campaign designed by the Royal Life Saving WA Branch, known as Watch Around Water (WAW). Conclusion: Caregiver supervision at public swimming pools remains an important issue, particularly the use of mobile phones and its deleterious impact on supervision. The WAW program plays an integral role in educating caregivers of supervision responsibilities. Furthermore, this study adds to the limited evaluation of the WAW program, and thus will help guide future improvements to ensure caregiver supervision is consistent. So what?: Further research is needed to create strategies to reduce mobile phone use among caregivers, in order to provide safer swimming environments. [ABSTRACT FROM AUTHOR]

Background: As of January 2020, 18 of 50 US states comprehensively banned almost all handheld cellphone use while driving, 3 states and the District of Columbia banned calling and texting, 27 states banned texting on a handheld cellphone, and 2 states had no general cellphone ban for all drivers. However, it remains unknown whether these bans were associated with fewer traffic deaths and whether comprehensive handheld bans are more effective than isolated calling or texting bans. We evaluated whether cellphone bans were associated with fewer driver, non-driver, and total fatalities nationally.Methods: We conducted a longitudinal panel analysis of traffic fatality rates by state, year, and quarter. Population-based rate ratios and 95% CIs were estimated comparing state-quarters with and without cellphone bans.Results: From 1999 through 2016, 616,289 persons including 344,003 drivers died in passenger vehicle crashes in the United States. Relative to no ban, comprehensive handheld bans were associated with lower driver fatality rates (adjusted rate ratio aRR = 0.93, 95% CI = 0.90, 0.97) but not for non-driver fatalities (aRR = 1.01, 95% CI = 0.95, 1.07) or total fatalities (aRR = 0.98, 95% CI = 0.94, 1.01). We found no differences in driver fatalities for calling-only bans (aRR = 1.00, 95% CI = 0.97, 1.03), texting-only bans (aRR = 1.02, 95% CI = 0.99, 1.05), texting plus phone-manipulating bans (aRR = 0.99, 95% CI = 0.93, 1.04), or calling and texting bans (aRR = 0.98, 95% CI = 0.88, 1.09).Conclusions: Comprehensive handheld bans were associated with fewer driver fatalities.

The dental profession has experienced a dramatic acceleration in the use of communication systems and information-based technologies over recent years, originating new paradigms for the prevention and promotion of oral health. The purpose of this systematic review was to determine the effect of teledentistry-based (telematic) strategies, reported in randomized controlled trials and quasi-randomized trials, with a focus on oral health prevention and promotion–related outcomes in patients of all ages. We searched Medline via PubMed, SCOPUS, and Web of Science from inception until August 2020, regardless of the language of publication. We selected studies for inclusion and conducted data extraction, assessed risk of bias (Cochrane tool), and evaluated the certainty of the evidence (GRADE approach) in duplicate and independently. Out of 898 potentially eligible references, we selected 43 for full-text screening, of which 19 studies proved eligible: 18 randomized controlled trials and 1 quasi-randomized study. Virtual interventions were mostly asynchronous via apps (n = 9), text messages (n = 9), or computer-aided learning (n = 1). The use of teledentistry as compared with conventional strategies may result in a large reduction in the plaque index (standardized mean difference, −1.18; 95% CI, −1.54 to −0.82; I 2 = 92%; low certainty) and will likely result in a large reduction in the gingival index (standardized mean difference, −2.17; 95% CI, −3.15 to −1.19; I 2 = 97%; moderate certainty) and in the incidence of white spot lesions (risk ratio, 0.48; 95% CI, 0.35 to 0.66; I 2 = 0%; moderate certainty), with an increased effect over time. Evidence suggests that teledentistry, particularly mHealth (messages and apps), is a promising clinical tool for preventing and promoting oral health, especially under the accelerated virtualization of dentistry. Future studies should include a broader spectrum of the population, including adults and elders, to better inform policy and implementation of teledentistry (PROSPERO: CRD42020192685).

Background: In the midst of the coronavirus disease 2019 (COVID-19) pandemic, there are many ways to communicate hygiene measures, such as memes and stickers that are widely used on social networks. We carried out a systematic review in order to determine the impact of stickers and memes as tools to face the COVID-19 pandemic, following the PRISMA guide. Methods: The search was carried out in scientific databases (MEDLINE / PubMed, ScientiDirect, Scielo, LILACS, and Latindex), and in public pre-publication servers (bioRxiv, SocArXiv, medRxiv and Preprints). The publications were identified using the terms (((meme) OR (sticker)) AND ((COVID-19) OR (SARS-COV-2)) AND (WhatsApp)) and the corresponding translations for Spanish and Portuguese. Results: In the initial search, 8434 studies were obtained, 7749 in Preprints, 446 in SocArXiv, 145 in ScientDirect, 82 in medRxiv, and 12 in PubMed. No studies were found in LILACS, Latindex, Scielo, or bioRxiv. Of the 51 studies included as eligible, all were eliminated for not meeting the study inclusion criteria. The majority (40 studies) were eliminated as studies were publications related to the social aspects related to COVID-19, but did not develop an analysis of stickers or memes. Conclusions: No studies were identified that met the inclusion criteria related to the role of stickers and memes as tools to face the COVID-19 pandemic. More studies are needed to estimate its role as a means of communication in health.

ABSTRACT Objective To reflect on the relationship between the nomophobia and the pandemic of COVID-19 and the nursing contributions to deal with this issue and its consequences. Method This reflective and theoretical study was based on the dialogue between the scientific literature on the subject and in dialogue and conceptual perspective of comprehensive care. Results Nursing strives to harmonize observed problems and can support individuals to reflect and discover a potential harmful habit regarding the use of cell phones, especially when undergoing treatments for other diagnoses. Final considerations Nursing, when accessing the emotional and subjective aspects of those under their care, helps to alleviate the symptoms of nomophobia and, in tune with the patient, promotes harmony in the face of the COVID-19 pandemic.

We explored the relationship between being phubbed by one's peers and selfie liking, and examined the mediating effect of attention seeking and the moderating effect of gender in this relationship. An online survey was conducted with 427 university students. The results reveal that peer phubbing was positively related to attention seeking and selfie liking. Further, attention seeking was positively related to selfie liking, and attention seeking mediated the relationship between peer phubbing and selfie liking. The indirect pathways involved gender differences, with a stronger indirect effect for men compared to that for women. Thus, gender moderated the relationship between peer phubbing and attention seeking, as well as the relationship between attention seeking and selfie liking. These findings illustrate that selfie-related behaviors may function as a buffer for being phubbed. Moreover, phubbed individuals are prone to engage in attention-seeking behavior and frequent selfie liking. [ABSTRACT FROM AUTHOR]

This work aims to evaluate the characteristics of the cell phone by employees, students and health professionals and investigate the relationship with the number and type of microorganisms present on the phone. Sociodemographic data and information on cell phone use were collected, in addition to the microbiological assessment of the phones. The data were analyzed in SPSS, through descriptive statistics of the variables. Among the 50 study participants, 82% were female, 96% used their cell phones at work and 70% performed some type of asepsis. Regarding microbiological collection, there was bacterial growth in 68% of cell phones, whose most isolated bacterium was negative coagulase Staphylococcus (47%). In addition, there was a growth of more than 100.000 CFU/mL in the cell phones of residents (26.5%) and undergraduates (23.5%). It is concluded that the use of the cell phone during the working day is frequent, which may be related to the number of contaminated devices. [ABSTRACT FROM AUTHOR]

The now taken-for-granted introduction of internet usage into the workplace changed the dynamics of work, productivity, and management, and this is now further complicated by the ubiquitous availability of personal cell phones, going beyond company supplied and (partially) controlled computers with internet connections. This paper studies the connection between internet and cell phone usage by employees and firm productivity. Using primary data collected via a selfreported survey, we conduct an empirical analysis utilizing information based on firm and industry characteristics. Results indicate that the level of non-workrelated internet and cell phone usage is significantly associated with firm productivity. Some of the negative aspects of internet availability can be mitigated by internet governance policies and systems to monitor the internet usage of employees. This paper offers suggestions so that firms are able to maintain the positive aspects of employee personal and business internet/cell usage while mitigating other more negative aspects including productivity losses.

Neck and low back pains are the leading causes of years lived with disability, and using computers or mobile devices in excess could be risk factors for back pain. Our aim was to evaluate the association of the length of time using computers and mobile devices with neck, mid-back and low back pains and the number of regions with pain. Cross-sectional study nested in the 1993 Pelotas birth cohort with young adults aged 22 years. Outcomes analyzed were neck, mid-back and low back pains and the number of regions with pain. Exposures were the number of daily hours using computers and mobile devices. Crude and adjusted analyses were performed to estimate prevalence ratios using Poisson regression. Almost half of the sample reported having back pain, the low back pain being the most prevalent. Compared with individuals using mobile devices for less than one hour, the prevalence of neck pain was 1.41 and 1.81 times higher among individuals using mobile devices from three to seven hours and for seven or more hours per day, respectively. Neck pain prevalence was 1.47 times higher among individuals using computers for more than two hours than among those not using computers. Using mobile devices for seven hours or more was associated to 1.19 times higher prevalence of low back pain. Using mobile devices in excess was associated to neck and low back pains, while the use of computers in excess was associated only to neck pain. It is important that guidelines are developed to recommend the adequate length of time that computers and mobile devices should be used to prevent back pain. [ABSTRACT FROM AUTHOR]

Delay discounting is a behavioral measure of impulsivity in which respondents choose between hypothetical smaller immediate rewards (SIR) or larger delayed rewards (LDR). Delay discounting questionnaires quantify impulsivity by calculating the rate that delayed rewards lose their subjective value for a particular participant or group. The purpose of the present study was to collect additional evidence on the relation of delay discounting and cell phone use in the college classroom. College students at the undergraduate and graduate level (N = 43) completed a brief survey about their cell phone use in the classroom as well as a delay discounting questionnaire. The primary dependent measures were self-reported duration and rate of cell phone use. Pearson product-moment correlations were calculated between participant characteristics and delay discounting rates. Hierarchical linear regression models were used to adjust for basic demographic variables and measure the independent effect of delay discounting rates on cell phone use. Delay discounting rates were correlated with age (r(39) = -.39, p =.012), duration of cell phone use (r(41) =.42, p =.005), and rate of cell phone use per hr (r(40) =.34, p =.026). Delay discounting rate significantly predicted duration of cell phone use after adjusting for age and sex (B = 0.31, SE = 0.13, p =.023). Delay discounting rate did not predict rate of classroom cell phone use in the regression model (p =.14), nor did it alter the predictive utility of the model (p =.14). [ABSTRACT FROM AUTHOR]

Background: Nomophobia is the fear of being disconnected from one’s mobile phone, prevailing in modern area. To the best of our knowledge, no Persian psychometric scales are available for investigating nomophobia among Iranians. Therefore, we here aimed to translate and validate the Nomophobia Questionnaire (NMP-Q) for being used in Iran. Methods:The NMP-Q was translated from English to Persian using a classical “backward and forward” procedure. Exploratory factor analysis (EFA) was carried out to explore the underlying factor structure of the translated questionnaire. A principal component analysis (PCA) approach with varimax rotation was further performed. Findings: 425 volunteer students were included. Among them, 80.2% were 20-30 years old. Men and women constituted 187 (44.0%) and 238 (56.0%) of the participants, respectively. 100 (23.5%) of the subjects were medicine graduates. Using mobile phones for more than 5 years was noted in 215 (50.6%) subjects. Also, 422 (99.3%) subjects connected to the Internet via their cellphones. Regarding cellphone usage, 301 (70.8%) subjects used them less than 5 hours a day, 158 (37.2%) subjects checked their cellphones less than 10 times a day, and 92 (21.6%) subjects checked their cellphones every 20 minutes. Eigenvalues and the scree-plot supported a 3-factorial nature of the translated questionnaire. NMP-Q showed an overall Cronbach's alpha coefficient of 0.93 (the coefficients of 0.90, 0.77, and 0.71 for the three factors, respectively). The first, second, and third factors explained 26.30%, 20.84%, and 17.60% of the variance, respectively. The total score of NMP-Q correlated with the hours spent with mobile phones, the years of using them, and the age. Conclusion: Our findings showed that the Persian version of the NMP-Q was a valid and reliable tool for evaluating nomophobia among Iranians.

• Distracted driving is a major motor vehicle crash risk for young drivers. • Perceived safety had the strongest association with texting and smartphone app use. • Social norms were associated with the sending a text/email. • Changing social norms and perceived safety could reduce distracted driving among young drivers. Distracted driving is a major risk factor for motor vehicle crashes, especially for young drivers. This study examines factors that contribute to the exposure of young drivers to distracted driving behaviors. Data from the 2015 National Survey on Distracted Driving Attitudes and Behaviors was used to determine the influence that perceived safety, likelihood to do or say something, social norms, and demographic variables have on self-reported cell phone distracted driving. Our population included 16–24-year old drivers. Dependent variables were texting (reading and sending a text/email) and smartphone app use while driving. Rao-Scott chi-squared tests and multivariate logistic regression models were applied. Sampling weights were applied to create nationally representative estimates and all statistical tests accounted for complex survey design. Among young drivers who report cell phone use while driving, 42% reported reading a text, 33% reported sending a text, and 23% reported smartphone app use. Multivariate regression results showed that perceived safety had the strongest association with reporting texting and smartphone app use while driving. In addition, social norms and age-education were significantly associated with reporting sending a text/email and reading a text/email while driving, respectively. The current study found significant relationships between attitudes and behaviors about cell phone use while driving and self-reported engagement in distracted driving. Interventions with an emphasis on changing perceived safety and social norms for young drivers could be beneficial for reducing engagement in cell phone use while driving. [ABSTRACT FROM AUTHOR]

Texting is used by many adolescents and has the potential to improve well-being, as youth can reach out for support immediately after experiencing a stressful situation. Many studies have examined whether texting is associated with well-being, but few have used experimental designs, preventing causal claims. In this experimental study, 130 adolescents (M age = 12.41) participated with a same-gender friend whom they texted regularly. Both adolescents completed a task that elicited stress and then engaged in one of the following randomly assigned activities: texting their friend, watching a video on a cellphone (passive-phone condition), or sitting quietly (no activity condition). Participants reported their mood and stress levels after the stress task and again after the activity. Heart rate variability was measured throughout. Participants who texted their friend reported higher moods (b = −.80, standard error [SE] =.24, p <.001, η p 2 =.09) and lower stress at the end of the study than those in the no activity condition (b =.51, SE =.25, p =.046, η p 2 =.04) and higher moods than adolescents in the passive-phone condition (b = −.74, SE =.25, p =.004, η p 2 =.08). No differences were noted between the passive-phone and no activity conditions. There were no differences in heart rate variability between the three conditions. The effects of texting on mood, self-reported stress, and heart rate variability did not differ by gender. Both boys and girls may benefit from texting a friend after experiencing a stressful event.
