Síndrome visual informático en pacientes menores de 35 años

Introducción: El síndrome visual informático o fatiga visual digital es una enfermedad causada por el cansancio ocular que provoca el pasar mucho tiempo frente a una pantalla. Objetivo: Diagnosticar el síndrome visual informático en pacientes menores de 35 años atendidos en la consulta de refracción. Métodos: Se realizó un estudio descriptivo prospectivo y transversal de pacientes atendidos en la consulta de refracción del Policlínico Especialidades del Hospital Provincial Docente Clínicoquirúrgico Saturnino Lora, durante el periodo de abril a junio de 2022. Resultados: Predominaron los pacientes en las edades comprendidas entre 26 y 35 años y del sexo femenino; los síntomas más frecuentes fueron el cansancio visual, ardor ocular, sensación de ojo seco, visión borrosa de cerca, ojo rojo y el dolor de cabeza después del esfuerzo visual. Los dispositivos digitales más usados fueron el celular y la computadora con un tiempo de uso de una a tres horas, destacándose este último con un tiempo superior a 4 horas. Los defectos refractivos constituyeron la principal causa de limitaciones visuales. Los pacientes con síndrome visual informático y alguna ametropía sin corrección fueron los que mayor cantidad de síntomas tuvieron, seguidos de los pacientes corregidos inadecuadamente. Conclusiones: Este síndrome afecta en gran medida a la población más joven. El adecuado interrogatorio y la incorporación de los procedimientos correctos en el estudio optométrico diario permitió el diagnóstico de tal síndrome en los pacientes atendidos y la corrección óptica pertinente.

Introduction: Digital visual syndrome or digital visual fatigue is a disease caused by the ocular fatigue provoked by spending much time in front of a screen. Objective: To diagnose the digital visual syndrome in patients under 35 years assisted in the refraction service. Methods: A prospective descriptive and cross-sectional study of patients assisted in the refraction service of the Specialties Polyclinic in Saturnino Lora Teaching Clinical Surgical Provincial Hospital, was carried out from April to June, 2022. Results: There was a prevalence of patients aged 26 and 35 and female sex; the most frequent symptoms were visual fatigue, ocular burning, dry eye sensation, closely blurred vision, red eye and headache after visual effort. The most used digital devices were the cellphone and the computer with a time of use from one to three hours, with emphasis in the last one with more than 4 hours. The refractive defects constituted the main cause of visual limitations. The patients with digital visual syndrome and some type of ametropia without correction were those with more symptoms, followed by the patients inadequately corrected. Conclusions: This syndrome affects the youngest population to a great extent. The appropriate interrogation and the incorporation of correct procedures in the daily optometric study allowed the diagnosis of such a syndrome in the assisted patients and the pertinent optic correction.

Etude du paiement électronique des agents de santé: cas de la campagne de vaccination contre la rougeole et la rubéole en Côte d'Ivoire / NA

La motivation des agents de santé à travers le paiement à temps et complet constitue l'un des éléments clés pour atteindre de bonne couverture vaccinale. Notre objectif était de décrire le paiement électronique utilisé lors de la campagne rubéole-rougeole et d'apprécier la satisfaction du personnel de santé. Nous avons réalisé une étude transversale à visée analytique qui s'est déroulée en Côte d'Ivoire du 15 janvier au 18 février 2019. La population d'étude était constituée des acteurs impliqués à la fois dans la campagne de vaccination contre la rougeole- rubéole en 2018 et dans le paiement électronique. Une recherche documentaire et des entretiens structurés ont permis le recueil des données. Les données ont été analysées à partir du logiciel R studio© version 2021. Le système assurant le paiement électronique se composait des autorités sanitaires, d'un opérateur privé de téléphonie mobile, d'un partenaire technique et financier et des agents de santé bénéficiaires. Un système de critères d'identification, des listes de validation et de vérification à plusieurs niveaux de la pyramide sanitaire a été mis en place. Un peu moins de trois quarts des acteurs du niveau primaire ont été satisfaits par ce mode de paiement. Le paiement électronique constitue un procédé pour améliorer le paiement des agents de santé durant les campagnes de vaccination. Des leçons d'un tel système de paiement devraient être tirées pour un déploiement à grande échelle.

Motivating healthcare workers through timely and complete payment is one of the key elements to achieve high vaccination coverage. Our objective was to describe the use of electronic payment during the measles-rubella campaign and assess the satisfaction of healthcare personnel. We conducted a cross-sectional analytical study in Côte d'Ivoire from January 15 to February 18, 2019. The study population consisted of individuals involved in both the measles-rubella vaccination campaign in 2018 and electronic payment. Data collection was done through documentary research and structured interviews. The data were analyzed using R Studio© software version 2021. The electronic payment system involved health authorities, a private mobile network operator, a technical and financial partner, and the beneficiary healthcare workers. A system of criteria for identifying lists, validation, and multilevel verification within the healthcare pyramid was established. Just under three-quarters of primarylevel actors were satisfied with this payment method. Electronic payment presents an opportunity to improve healthcare worker payment during vaccination campaigns. Lessons from such a payment system should be drawn for large-scale deployment.

Relation between neuroticism and tendency of mobile phone addiction among nursing undergraduates： the mediating role of perceived stress and self-control / 四川精神卫生

BackgroundNegative effects of mobile phone addiction on undergraduate students have led to several health problems including depression， anxiety， attention deficit disorder， cognitive impairment and sleep disturbance. The undergraduate nursing students serve as an important reserve force of the clinical nursing work， and their poor psychological health would have a non-ignorable impact on the quality of the nursing work and the nurse-patient relationship in the future. ObjectiveTo investigate the relation between neuroticism and tendency of mobile phone addiction among undergraduate nursing students， and to examine the pathways through which perceived stress and self-control play a role in the relation by constructing a chain-mediated model. MethodsFrom February to March 2023， a total of 900 undergraduate nursing students across 10 universities in Xi'an， Shaanxi Province were selected through convenient sampling method. Several scales were adopted to assess undergraduate nursing students respectively， including the neuroticism subscale of Eysenck Personality Questionnaire-Revised Short Scale for Chines （EPQ-RSC）， Perceived Stress Scale （PSS）， Self-Control Scale （SCS） and Mobile Phone Addiction Tendency Scale （MPATS）. The assessment were conducted on multiple aspects of these students including neurotic personality， subjective stress， self-control and mobile phone addiction tendency. Model 6 in the SPSS Macro Process 4.1 was used to examine the mediating effect of perceived stress and self-control between neuroticism and mobile phone addiction tendency among undergraduate nursing students. Results① Among the 900 students， 314 cases （34.89%） were found to be addicted to mobile phones. ② The score of neuroticism subscale in EPQ-RSC of nursing undergraduates was positively correlated with the total scores of PSS and MPATS （r=0.400， 0.287， P<0.01）， and negatively correlated with score of SCS （r=-0.364， P<0.01）. The total score of MPATS was positively correlated with the total score of PSS （r=0.362， P<0.01）， and negatively correlated with the total score of SCS （r=-0.468， P<0.01）. The total score of SCS was negatively correlated with the total score of PSS （r=-0.515， P<0.01）. ③ Perceived stress and self-control performed partial mediation between neuroticism personality and mobile phone addiction tendency （with indirect effect values of 0.056 and 0.065， respectively， accounting for 19.72% and 22.89% of the total effect）. Perceived stress and self-control played a chain mediating role between neuroticism personality and mobile phone addiction tendency （with an indirect effect value of 0.064， accounting for 22.54% of the total effect）. ConclusionNeuroticism personality， perceived stress and self-control are confirmed to play important roles in mobile phone addiction tendency among undergraduate nursing students. Neuroticism personality not only directly affects the tendency of mobile phone addiction， but also affects their mobile phone addiction tendency through the chain mediating effect of perceived stress and self-control.［Funded by The 2020 Annual Project of the 13th Five-Year Plan of Education Science in Shaanxi Province （number， SGH20Y1386）］

Objetivo: Estimar la adicción a los teléfonos inteligentes en adolescentes mujeres tras la pandemia por la COVID-19. Métodos: Estudio transversal realizado en noviembre y diciembre del 2022, en una institución educativa pública de Ica, Perú. Participaron 581 adolescentes que respondieron a un cuestionario con variables generales y la Escala de Adicción a los Teléfonos Inteligentes. Se aplicó un análisis estadístico descriptivo y multivariado mediante modelos lineales generalizados de la familia Poisson para evaluar la asociación entre las variables. Resultados: De las participantes, el 21,7 % reveló adicción a los teléfonos inteligentes y el 48,7 % se encuentra en riesgo alto de dependencia. Los conflictos familiares en el hogar (razón de prevalencia ajustada - RPa= 1,41; intervalo de confianza -IC 95 %: 1,00-1,99) y los sentimientos de vergüenza (RPa= 1,44; IC 95 %: 1,01-2,03), se asociaron a mayor adicción a los teléfonos inteligentes. No obstante, el sentimiento de tristeza, ansiedad o depresión y el hecho de sentirse rechazado por la sociedad presentaron asociación, no ajustada. Conclusiones: La adición a los teléfonos inteligentes y el riesgo de padecer este trastorno es alto en las adolescentes; existen variables generales susceptibles de ser modificadas que podrían mermar dicha afección comportamental inducida o potenciada por la pandemia de la COVID-19.

Introduction: The COVID-19 pandemic brought with it changes in human behavior and psychic conditions that affect mental health. Objective: Estimate smartphone addiction in female adolescents after COVID-19 pandemic. Methods: Cross-sectional study, conducted during November to December 2022, in a public educational institution in Ica, Peru. A total of 581 adolescents participated and answered a questionnaire with general variables and the Smartphone Addiction Scale. A descriptive and multivariate statistical analysis was applied using Poisson family generalized linear models to evaluate the association between variables. Results: Of the participants, 21.7% revealed addiction to smartphones and 48.7% were at high risk of dependence on these devices. Family conflicts at home (adjusted prevalence ratio-RPa = 1.41; 95% confidence interval-CI: 1.00-1.99) and feelings of shame (RPa = 1.44; 95% CI: 1.01-2.03), were associated with higher smartphone addiction. However, feelings of sadness, anxiety or depression and feeling rejected by society showed an unadjusted association. Conclusions: Smartphone addiction and risk for this disorder is high in adolescent girls; there are general variables amenable to modification that could diminish such a behavioral condition induced or potentiated by the COVID-19 pandemic.

Experiencias del cuidador familiar con la utilización de las Tecnologías de la Información y la Comunicación: Implementación de una intervención educativa / Experiences of the family caregiver with the use of Information and Communication Technologies: Implementation of an educational intervention

Introducción: Las Tecnologías de la Información y Comunicación (TICs) son un recurso a través del cual los profesionales de la salud pueden proporcionar apoyo y asesoría a distancia. Objetivo: Describir las experiencias de una cuidadora familiar (CF) con el uso de las TICs en la implementación de una intervención educativa como apoyo para su autocuidado y el cuidado del adulto mayor (AM). Metodología: Estudio de caso con abordaje cualitativo. Una pasante de la licenciatura en Enfermería y Obstetricia implementó una intervención educativa en una CF del 15 diciembre 2020 al 25 junio 2021, periodo de pandemia por COVID-19. La recolección de datos se realizó a partir de entrevistas a profundidad, mensajes de texto y voz de WhatsApp, así como por observación. Se realizó análisis de contenido tipo temático según de Souza Minayo. Resultados: Se identificó el teléfono celular como el dispositivo más utilizado, las funciones de videollamada y mensaje de voz de WhatsApp como las herramientas más útiles y preferidas por la CF, y las infografías y videos como los materiales educativos más adecuados para esta población. Limitaciones: Solo se incluyó una CF y un AM, lo cual puede generar un sesgo de respuesta, ya que la CF quizás estuvo más motivada y dispuesta a participar que otros cuidadores hipotéticos. Valor: Implementar un nuevo canal de comunicación entre el profesional de enfermería, el AM, la CF y otros familiares. Conclusiones: El uso de las TICs fue aceptado por la CF para recibir capacitación en su autocuidado y cuidado del AM.

Introduction: Health professionals can use Information and Communication Technologies (ICTs) to provide support and advice at a distance. Objective: Description of the experiences of a family caregiver (FC) with the use of ICTs in the implementation of an educational intervention to support her self-care and the care of the Older Adult (OA). Methodology: Case study with qualitative approach. An undergraduate intern in Nursing and Midwifery implemented an educational intervention with a FC from December 15, 2020 to June 25, 2021, during the covid-19 pandemic. Data collection was gathered with in-depth interviews, Whatsapp text and voice messages, as well as direct observation. Thematic type content analysis was performed according to de Souza Minayo. Results: The cell phone was identified as the most used device, Whatsapp video call and voice message functions as the most useful and preferred tools by the FC, and infographics and videos as the most appropriate educational materials for this population. Limitations: Only one female FC and one male OA were included in this study. This may generate response bias, as the FC was perhaps more motivated and willing to participate than other hypothetical caregivers. Value: Implementation of a new communication channel between the nursing professional, the OA, the FC, and other family members. Conclusions: Training in the use of ICTs was accepted by the FC to improve her self-care and care of the OA.

Exposición a pantallas de niñas, niños y adolescentes: recomendaciones, límites y controversias en el marco del distanciamiento social obligatorio: un estudio cualitativo / Child and Teenage Screen Exposure: Recommendations, Limits,and Controversies in the Context of Enforced Social Distancing: a Qualitative Study

Introducción: la utilización de pantallas durante la niñez y la preocupación por su potencial daño aumentaron en los últimos años. La recomendación de no superar dos horas diarias de uso resultó controvertida durante la pandemia por COVID-19. El objetivo principal de esta investigación fue explorar las opiniones y actitudes de los profesionales con respecto al uso de pantallas y comprender cómo se modificaron durante dicha pandemia. Materiales y métodos: estudio exploratorio con enfoque cualitativo y estrategia de teoría fundamentada, realizado entre 2020 y 2021.Participaron 23 profesionales (pediatras y generalistas) en cuatro grupos focales. Se realizaron lecturas del material desgrabado para interpretación del contenido. El análisis incluyó la generación de códigos que fueron agrupados en cinco ejes temáticos. Resultados: los ejes resultantes fueron: 1) temática de las pantallas en la consulta ambulatoria de niños sanos, 2) percepción sobre daños, 3) percepción sobre beneficios, 4) pantallas en épocas de ASPO (Aislamiento Social Preventivo y Obligatorio) y 5) pensamientos y acciones contradictorios sobre el uso de pantallas. Discusión: a la hora de recomendar sobre exposición a pantallas, en nuestros entrevistados predominó la intuición personal por sobre la evidencia científica disponible. Reconocieron que el contexto de ASPO visibilizó algunos beneficios asociados a la conectividad que brindan estos dispositivos. Conclusión: nuestros resultados muestran que la percepción sobre las pantallas se está volviendo cada vez más neutral en términos del balance entre sus riesgos y beneficios, conduciendo a que los profesionales sean más flexibles en sus recomendaciones al respecto.

Introduction: screen use during childhood and potential harm concerns have increased in recent years. Advice not to allow more than two hours of screen use per day was contested during the COVID-19 pandemic. The primary purpose of this research was to probe the opinions and attitudes of professionals regarding the use of screens and to understand how these changed during the pandemic. Materials and methods: this exploratory study, with a qualitative approach and theory-based strategy, was made between 2020 and 2021, and involved the participation of 23 professionals (pediatricians and general practitioners) in four focus groups. The recorded material was analyzed for content interpretation. The analysis included generating codes that were grouped into five thematic areas. Results: the resulting axes were: 1) the issue of screens in the outpatient practice of healthy children; 2) perception of harm; 3) perception of benefits; 4) screens in times of Preventive and Compulsory Social Isolation (ASPO, for its acronym in Spanish); and 5) contradictory thoughts and actions on the use of screens. Discussion: when making recommendations regarding screen exposure, the interviewees' intuition predominated over available scientific evidence. They recognized that the ASPO context highlighted some of the benefits associated with the connectivity provided by these devices. Conclusion: our results show that awareness of screen displays is becoming increasingly neutral concerning the trade-off between their risks and benefits, prompting practitioners to become more flexible in their recommendations.

Using the cell phone while standing or walking affects balance and mobility in people with Parkinson's disease / O uso do celular em pé ou durante a caminhada afeta o equilíbrio e a mobilidade de pessoas com doença de Parkinson

Abstract Background Cell phones are part of peoples' lives. The literature indicates risks when cell phones are used during a secondary motor task. Studies addressing this topic in people with Parkinson's disease are still scarce. Objective To investigate the impact of daily dual tasks with cell phone on balance and mobility in people with Parkinson's disease, compared to healthy control peers. Methods Participants with Parkinson's disease and controls underwent three motor tasks: (1) Standing and walking without using a cell phone; (2) Standing and walking while talking on the phone; and (3) Standing and walking while texting messages on the phone. Assessments involved balance and mobility tests. Statistical analysis was performed with multivariate analysis of variance, comparing main effect for group (Parkinson's disease × control), task (using × not using cell phone) and interactions (group × task). Significance was set at 5%. Effect sizes are reported. Results Participants with Parkinson's disease showed worse balance (p = 0.001, effect size of 0.471) and mobility (p = 0.001, effect size of 0.472) than control peers. The use of cell phone while performing a secondary motor task affected both groups (p = 0.005, effect size of 0.673 for balance and p = 0.001, effect size of 0.549 for mobility). The dual task impact, however, was higher in the Parkinson's disease group (p = 0.009, effect size of 0.407 for mobility). Conclusion Daily dual tasks with cell phones increase imbalance and mobility risks in Parkinson's disease. People should be careful when using their cell phone while standing or walking.

Resumo Antecedentes Aparelhos celulares fazem parte da vida das pessoas. A literatura aponta riscos quando o uso do celular está associado a uma tarefa motora. Estudos abordando esse tema na doença de Parkinson são escassos. Objetivo Investigar o impacto de tarefas-duplas com o celular sobre equilíbrio e mobilidade de pessoas com doença de Parkinson, na comparação com controles saudáveis. Métodos Participantes com e sem doença de Parkinson foram submetidos a três tarefas: (1) Ficar em pé e caminhar sem o celular; (2) Ficar em pé e caminhar enquanto conversa ao celular; e (3) Ficar em pé e caminhar enquanto digita mensagens. As avaliações envolveram testes de equilíbrio e mobilidade. Os procedimentos estatísticos envolveram testes de análise múltipla de variâncias, com análise de efeito principal para os fatores grupo (doença de Parkinson x controle), tarefa (com celular × sem celular) e interação (grupo × tarefa). Significância foi estipulada em 5%. Tamanhos de efeito foram reportados. Resultados Participantes com doença de Parkinson apresentaram pior equilíbrio (p = 0,001; tamanho do efeito: 0,471) e mobilidade (p = 0,001; tamanho do efeito: 0,472) que controles. O uso do celular afetou ambos os grupos (p = 0,005, tamanho do efeito de 0,673 para equilíbrio e p = 0,001, tamanho do efeito de 0,549 para mobilidade). O impacto da tarefa-dupla, contudo, foi maior no grupo Parkinson (p = 0,009; tamanho do efeito de 0,407 para mobilidade). Conclusão Tarefas simultâneas com o celular causam desequilíbrio e problemas de mobilidade na doença de Parkinson. As pessoas devem ter cuidado ao utilizar celulares durante atividades em pé e ao caminhar.

Predictores del uso problemático del teléfono celular en adolescentes costarricenses

(analítico) Este artículo tiene por objetivo investigar los efectos del apoyo familiar y del grupo de pares, junto con la satisfacción con la vida, sobre el uso problemático de los teléfonos celulares entre los adolescentes costarricenses. Basado en datos de la encuesta nacional Global Kids Online, se desarrollaron modelos de ecuaciones estructurales para predecir el uso problemático de teléfonos celulares de adolescentes (M = 14.8, n = 530). Los resultados muestran que el apoyo entre pares correlaciona positiva y directamente con el uso problemático del teléfono celular, mientras que la percepción de la satisfacción con la vida tiene una correlación opuesta, funcionando como un factor protector. El apoyo del grupo de pares y, más aún, el apoyo familiar, ejercen efectos indirectos sobre el uso problemático del teléfono móvil.

(analytical) This study aimed to research the effects of family support and peer group support, along with the life satisfaction, on the problematic use of cell phones among costa rican adolescents. Based on data from the national survey Global Kids Online, structural equation models were developed in order to predict the problematic use of cell phones of adolescents investigated in this study (M=14.8, n = 530). The main findings indicate that peer support has a positive and direct correlation with the problematic use of the cell phone, while the perception of the life satisfaction is correlated in the opposite direction, functioning as a protective factor. Peer and family support have an indirect protective effect against the problematic use of cell phones, stronger in the case of family support.

(analítico) Este estudo teve como objetivo pesquisar os efeitos do apoio familiar e do grupo de pares, juntamente com a satisfação com a vida, no uso problemático de telefones celulares entre adolescentes costarriquenhos. Com base nos dados da pesquisa nacional Global Kids Online, foram desenvolvidos modelos de equações estruturais para prever o uso problemático de celulares dos adolescentes investigados neste estudo (13 a 17 anos; n = 530). Os principais achados indicam correlação positiva e direta do apoio dos pares com o uso problemático do celular, enquanto a perceção da satisfação com a vida está correlacionada de maneira inversa, funcionando como fator de proteção. O apoio dos pares e da família tem um efeito protetor indireto contra o uso problemático de telefones celulares, mais forte no caso do apoio familiar.

Occurrence of dry eye in mobile phone users

Background: Most Indians today own one or more mobile phones. The average time of phone usage per person per day is 4.8 h and the excess usage of mobile phone is an emerging cause of dry eye. Although some studies have established this relation, not many studies focus on South India. Our study aims to highlight the South Indian population. Aim and Objective: To study the prevalence of dry eye among medical students of 18–25 years. Materials and Methods: This is a cross-sectional study, whose participants are undergraduate medical students, both males and females, between 18 and 25 years. Schirmer’s test was done for each candidate after answering an Ocular Surface Disease Index questionnaire. Results: The most frequent symptom reported by the participants at the time of answering the questionnaire was soreness and irritation of the eye (8%). The most common long-term symptom reported was burning and watering of eyes of tolerable severity (27%). Some participants experienced uncomfortable and bothersome eye fatigue. Conclusion: Dry eye in the form of symptoms of both dryness of eye and reflex epiphora is present in the population under study. About 76% of the study population use their phones for over 3 hours a day. The soreness and irritation of eyes, watering and burning of eyes are attributed to the mobile phone usage for more than 6 hours per day.

Effect of duration of per day exposure to electromagnetic radiation from mobile phone on verbal and visual memory in male adults

Background: Mobile phones (MPs) are mostly kept close to the head while making a phone call, and therefore, the electromagnetic radiation (EMR) from MP may be potentially damaging to the brain and hence its neurological functions. Reports available on the effect of MP radiation on human memory is scarce and inconclusive so far. Aims and Objectives: The present study was planned to evaluate the effect of per day durations of EMR exposure through MP calls on verbal and visual memory using paper and pencil cognitive tests. Materials and Methods: Twenty healthy right-handed male subjects within age group 18–40 years were recruited for the study and divided into two groups. Those making MP calls of more than 1 h/day were placed in the Group-A and those making calls <1 h/day in Group-B. Both groups were evaluated for verbal and visual memory using Rey auditory verbal learning test (RAVLT) and playing card test (PCT) before and after exposure to EMR for 10 min. Statistical analysis was done by paired “t” test. Results: Group-B performed significantly better in RAVLT than Group-A. No significant difference was seen in PCT. After exposure to EMR from MP, the performance in PCT of both the groups deteriorated significantly. Conclusion: Longer per day exposure to EMR from MP affects verbal memory, while visual memory may be more susceptible to acute exposures.

A comparative study of telephone and face-to-face use of phone screening interview for autistic spectrum disorder symptoms (PSI-ASD) / Estudo comparativo da aplicação por telefone e presencial da entrevista de triagem por telefone de sintomas do espectro autista (PSI-TEA)

ABSTRACT Objective: Describe reliabilities evidence of the Phone Screening Interview (PSI), a telephone screening interview for autism spectrum disorder (ASD) symptoms, capable of investigating mild to moderate ASD symptoms. Moreover, the PSI also works for verbal and non-verbal children and is consistent with the DSM-5 diagnostic criteria. Methods: An interview was performed with sixty-eight parents of children between 2 and 15 years old attended by the Psychiatry Ambulatory of Santa Casa de Misericórdia do Rio de Janeiro through the PSI in person and by telephone. Results: No significant differences in comparison between averages of the total score of the face-to-face and telephone applications were observed. The agreement analysis between the items indicated three items with lower values, leading to the modification of some questions, culminating in a new interview version for further studies. Given the disagreement in the values found, the order of application of the interviews seems to not impact the results, demonstrating strong correlations between both interviews, even with a different order of application. Aiming to facilitate the use of the scale by different examiners, the interobserver reliability was investigated, which did not show significant differences in the means. Conclusion: The study suggests that the telephone interview can be used similarly to the face-to-face interview, by different evaluators, with no impact on its efficiency in detecting ASD symptoms.

RESUMO Objetivo: Descrever evidências de confiabilidade da Phone Screening Interview (PSI), uma entrevista para rastreio telefônico de sintomas do Transtorno do Espectro Autista (TEA) de fácil aplicação, capaz de investigar sintomas de TEA leve a moderado, aplicável a crianças verbais e não verbais e consistente com os critérios diagnósticos do DSM-5. Métodos: Sessenta e oito pais de crianças com idade entre 2 e 15 anos atendidas pelo Ambulatório de Psiquiatria da Santa Casa de Misericórdia do Rio de Janeiro foram entrevistados por meio da PSI, tanto de maneira presencial quanto telefônica. Resultados: As médias da pontuação total da aplicação presencial e telefônica foram comparadas, não sendo obtidas diferenças significativas. A análise de concordância entre os itens apontou três itens com valores muito baixos, levando à modificação de algumas perguntas, culminando em uma nova versão, para estudos posteriores. Diante da discordância de valores encontrada, foi verificado que a ordem de aplicação das entrevistas não impactaria os resultados, demonstrando fortes correlações entre as entrevistas, mesmo com ordem de aplicação diferente. Para viabilizar o uso da escala por diferentes examinadores, investigou-se a confiabilidade interobservadores, que não mostrou diferenças significativas nas médias. Conclusão: O estudo sugere que a entrevista telefônica pode ser utilizada de forma semelhante à presencial, por diferentes avaliadores, sem impacto em sua eficiência na detecção de sintomas de TEA.

Sedentary behavior in young adults using ecological momentary assessment: an image observation protocol / Comportamento sedentário em adultos jovens por avaliação momentânea ecológica: protocolo de observação por imagem

ABSTRACT New ways to obtain information on sedentary behavior (SB) have recently been explored. This study aimed at assessing the self-reported posture agreement by using the Ecological Momentary Assessment (EMA). The images were sent by an observation protocol created in a form that would be answered via the mobile phone of young adults. The bank of images was provided by 41 university students. Such images were obtained from a project carried out in 2019, which was based on the taxonomy of sedentary behavior. The following positions were assessed: sitting, lying/reclining and standing, comparing the images provided with the self-reported SB by using EMA, which was collected via cell phone. The agreement was assessed by two researchers independently. Data analysis was based on descriptive statistics, Student's t test, chi-squared test, and Cohen's k in SPSS 25 with P<0.05. The inter-rater reliability was strong/substantial, that is, 87.6% (rater 1; k = 0.696) and 88.6% (rater 2; k = 0.720). The image observation protocol created in an electronic form could discriminate the behavior adopted by the participants, as well as it could be used independently, only for recording EMA and/or the image/photograph.

RESUMO Novas formas de se obter informações sobre o comportamento sedentário (CS) têm sido exploradas recentemente. O objetivo do presente estudo foi verificar a concordância da postura auto-relatada por meio da Avaliação Momentânea Ecológica (AME). As imagens foram enviadas por meio de um protocolo de observação criado em um formulário respondido pelo telefone celular de adultos jovens. Foi utilizado um banco de imagens fornecido por 41 universitários, obtidas por um projeto realizado em 2019 com base na taxonomia do comportamento sedentário. As seguintes posições foram analisadas: sentada, deitado/reclinado ou em pé, comparando a imagem fornecida com o CS auto-reportado por meio da AME, que foi coletada por telefone celular. A concordância foi realizada por dois pesquisadores de modo independente. A análise dos dados foi realizada pela estatística descritiva, t de Student, qui-quadrado e k de Cohen no SPSS 25 com P<0,05. A concordância entre os avaliadores foi forte/substancial de 87,6% (avaliador 1; k = 0,696) e de 88,6% (avaliador 2; k = 0,720). O protocolo de observação por imagem criado por formulário eletrônico conseguiu discriminar o comportamento adotado pelos participantes, bem como viável de ser utilizado de modo independente, somente para o registro da AME e/ou da imagem/fotografia.

Status quo and influencing factors of computer vision syndrome among college freshmen in Tianjin / 中国学校卫生

Objective@#To investigate the current situation and associated factors of computer vision syndrome (CVS) among college freshmen in Tianjin during the COVID-19 epidemic, and to provide a reference for visual comfort of college students.@*Methods@#A total of 868 college freshmen from one university in Tianjin were administered with CVS qualitative analysis questionnaire, eye health status questionnaire and eye health examination during Oct to Dec 2021. Chi square test and multivariate Logistic regression were used for data analysis.@*Results@#The detection rate of CVS among the included students was 68.5% ( n =595) and was higher in females (72.2%) than in males (61.7%). The CVS detection rate in girls, students without myopia, >30 min sleep onset, >1 h mobile phone usage, and ≤8 h sleep duration (72.2%, 70.4%, 81.1%, 72.7%, 71.2%) were significantly higher than boys, students with low grade myopia, sleep onset required ≤30 min, use mobile phone for ≤1 h, and sleep duration >8 h(61.7%, 63.3 %, 67.4%, 65.9%, 61.1%) ( χ 2=10.08, 3.94, 5.89, 4.40, 7.94, P ＜0.05). Differences in CVS detection rates varied significantly by daily electronic device usage and academic stress students ( χ 2=22.03, 21.24, P ＜0.05). Multivariate Logistic regression analysis showed that daily use of electronic devices 4-6, 7-9, ≥10 h, sleep onset required >30 min, moderate to higher academic pressure were positively associated with CVS ( OR=1.95, 2.94, 2.30, 2.39, 3.51, 4.41, P ＜0.05), boys, low grade myopia, night sleep time >8 h were negatively associated with CVS ( OR=0.65, 0.70, 0.65, P ＜0.05).@*Conclusion@#The detection rate of CVS among freshmen in a university in Tianjing is high. Attention should be paid to the CVS situation of students with e learning, and general public should also be educated to reduce the time of unnecessary electronic product use and ensure night sleep to reduce the prevalence of CVS.

The relationship between mobile phone dependence and academic burden among junior middle school students in Guizhou Province / 中国学校卫生

Objective@#To explore the relationship between mobile phone dependence (MPD) and academic burden among junior middle school students in Guizhou Province, under the "double reduction" policy by using a multi level model, so as to provide a basis for preventing the occurrence of MPD.@*Methods@#From December 2021 to January 2022, 7 868 students from grade 1 to grade 3 in 3 cities (prefecture) of Guizhou Province were selected by multi stage stratification random sampling method, and on site investigation was conducted by self compiled questionnaire and Self rating Questionnaire for Adolescent Problematic Mobile Phone Use(SQAPMPU). Using MLwiN 2.30 to fit a multi level model of the relationship between MPD and academic burden among junior middle school students.@*Results@#The MPD detection rate of junior middle school students in Guizhou Province was 20.9%. The multi level model revealed that MPD of junior middle school students was clustered at the level of school and class ( χ 2= 1 565.32 , P <0.01), and high perceived academic pressure had a positive predictive effect on MPD among junior middle school students ( β =1.96). Homework duration ≥90 min/d at weekends had a negative predictive effect on MPD ( β =-0.55), while participation in off campus training on learning days had a positive predictive effect ( β =1.66)( P <0.05).@*Conclusion@#The MPD occurrence level is higher among junior middle school students in Guizhou Province. Perceived academic pressure, time spent on homework during weekends, off campus training and other academic burdens have an impact on MPD among junior middle school students, which should be a cause of concern for schools, families and social departments.

Associations of mobile phone use with male semen quality and sex hormones / 环境与职业医学

Background Experimental studies have shown that radiofrequency electromagnetic waves emitted by mobile phones can cause adverse effects on male reproductive health, including decreased semen quality and altered sex hormones. However, the results of epidemiological studies on the relationship between mobile phone use and male semen quality are inconsistent. Furthermore, there are few epidemiological studies on the association of mobile phone use with sex hormones. Objective To explore the associations of mobile phone use with male semen quality and sex hormones. Methods A total of 2045 men visited the reproductive medicine center of a hospital in Wuhan and ordered infertility examination were recruited from December 2018 to January 2020. Information on mobile phone use was obtained using a questionnaire. Among them, 1232 and 1694 men were eligible for semen quality analyses and sex hormone analyses, respectively. Multiple linear and logistic regression models were used to analyze the associations of mobile phone use with male semen quality and sex hormones. Results After adjusting for potential confounders, there was no statistically significant associations of mobile phone use with sperm progressive motility, sperm total motility, sperm concentration, sperm count, or serum luteinizing hormone (P>0.05). However, serum total testosterone showed a declined tendency with increasing daily duration of mobile phone use (Ptrend=0.08). Compared with men with daily mobile phone use of 0-2 h, men with daily mobile phone use of 2.1-5, 5.1-8, and >8 h showed decreased serum total testosterone concentrations by 6.29% (95%CI: 0.40%-11.84%), 6.01% (95%CI: 0.60%-12.19%), and 7.87% (95%CI: 0.40%-14.79%), respectively. Conclusion Mobile phone use is not associated with male semen quality and serum luteinizing hormone, but increasing daily duration of mobile phone use is potentially associated with a tendency to lower male serum total testosterone.

Bidirectional associations between cellular phone use behaviors and depressive symptoms in college students: a follow up study / 中国学校卫生

Objective@#The study aimed to describe the prevalence of mobile phone use and depressive symptoms and to examine the bidirectional associations between the two among college students, providinb evidence for mental health promotion among college students.@*Methods@#A longitudinal study with follow up at 6 month intervals was conducted in 1 135 students from 2 universities in Hefei, Anhui Province and Shangrao, Jiangxi Province who were selected between April and May 2019. The last follow up was conducted between April and May 2021 based on questionnaire survey, and 999 valid participants were obtained after matching. The self designed questionnaire was used to investigate the duration of cellular phone use and use of cellular phone functions among college students. The Self rating Questionnaire for Adolescent Problematic Mobile Phone Use (SQAPMPU) and the Patient Health Questionnaire-9 (PHQ-9) were used to assess cellular phone dependence and depressive symptoms among college students. Pearson correlation analysis was used to examine the correlation between cellular phone use behavior and depressive symptoms at baseline and 2 years later; linear regression model was used to analyze the linear association between cellular phone use behavior and depressive symptoms scores; autoregressive cross lagged model was used to analyze the bidirectional associations between cellular phone use behaviors and depressive symptoms among college students over time.@*Results@#The prevalence of mobile phone dependence and depressive symptoms among college students at baseline were 24.3% and 42.4%, respectively. The mean duration of mobile phone use among college students at baseline and the 2 year follow up were (2.84±0.90)h/d and (2.02±1.05)h/d, respectively; the mean scores of mobile phone dependence were (23.30±9.00) and (23.29±10.45), respectively; the mean scores of mobile phone function use were (30.12±6.66) and (29.12±7.27), respectively; and the mean scores of depressive symptoms were (4.51±4.76) and (2.61±4.40), respectively. Pearson correlation analysis showed there were significant positive correlations between duration of cellular phone use, cellular phone dependence, use of cellular phone functions at baseline or 2 years later and depressive symptoms 2 years later( r =0.08-0.50, P <0.05). Linear regression models showed a significant positive association between cellular phone dependence at baseline and depressive symptoms ( β=0.26, 95%CI =0.23-0.29) at baseline and 2 years later ( β=0.12, 95%CI =0.09-0.15). Autoregressive cross lagged models showed that cellular phone dependence at baseline positively predicted depressive symptoms 2 years later ( β =0.04) and depressive symptoms at baseline positively predicted cellular phone dependence 2 years later( β =0.23)( P <0.05).@*Conclusion@#There was a bidirectional association between cellular phone dependence and depressive symptoms among college students. Reducing cellular phone dependence is of positive significance for improving college students mental health.
