视屏暴露和户外活动与幼儿睡眠的关联研究

目的 分析视屏暴露和户外活动与幼儿睡眠的相关性,为预防和干预儿童睡眠问题提供科学依据。方法 基于已建立的马鞍山市母婴健康出生队列,对2015年6月—2016年6月出生的单胎活产儿,随访至2岁,收集社会人口统计学、视屏暴露、户外活动和睡眠情况的资料。共获得有效问卷1 575份,男童833人,女童742人。使用χ²检验和Logistic回归模型对数据进行分析。结果 幼儿睡眠质量差的发生率为26.16%;电视打开时间(不一定在看)≥2 h/d、看电视≥1 h/d、玩手机≥30 min/d分别占50.73%、45.21%和26.03%,户外活动≥2 h/d的比例为71.30%;去户外场所的频率≥2次/周和在户外场所≥1 h/次的比例分别为76.31%和37.71%。调整人口统计学等混杂因素后,打开电视时间(不一定在看电视)≥2 h/d(OR=1.40,95%CI:1.11～1.77)、看电视时间≥1 h/d(OR=1.39,95%CI:1.11～1.75)、玩手机时间≥30 min/d(OR=1.55,95%CI:1.21～1.99)均会增加幼儿睡眠质量差发生的风险;去户外场所的频率≥2次/周(OR=0.72,95%CI:0.55～0.93)和在户外场所时间≥1 h/次(OR=0.78,95%CI:0.62～0.99)则能降低发生幼儿睡眠质量差的风险。结论 幼儿睡眠问题存在一定比例,视屏暴露和户外活动均与幼儿睡眠相关,在儿童保健门诊中应对家长进行科学指导,减少视屏暴露时间,增加户外活动,以减少儿童睡眠问题的发生。     

Neighborhood social environments,healthy resources,and adult diabetes: Accounting for activity space exposures

This study broadens contextual environments to include adults’ activity spaces—inside and outside the residential neighborhood—to examine how contextual exposures shape type 2 diabetes risk. We use novel longitudinal data from the Los Angeles Family and Neighborhood Survey, construct time-weighted exposure measures of adults’ social-structural and healthy resource environments, and execute random effects logistic models predicting the probability of being diabetic. Results indicate that residential and activity space exposures are independently associated with adult diabetes, and that residential and activity space healthy resources combine to influence diabetes risk in synergistic ways. Living in more socioeconomically advantaged neighborhoods reduces diabetes risk, particularly when spending time in activity spaces with greater access to recreational facilities. Moreover, healthier activity space environments may compensate for living in neighborhoods devoid of healthy food options to lessen diabetes risk. Adopting an activity space framework can inform multilevel interventions aimed at alleviating type 2 diabetes and other chronic ailments.     

某钢丝绳生产企业职业危害现状调查及控制对策

目的了解某钢丝绳生产企业职业病危害现状,为控制该企业职业病危害因素提供依据。方法通过对某钢丝绳生产企业进行职业卫生现场调查、职业病危害因素检测,收集有关数据和资料,结合职业病危害防护设施、个人职业病危害防护、应急救援措施、职业健康检查结果等进行分析评价。结果粉尘、毒物、高温检测结果均符合国家职业卫生标准,合绳捻股车间捻股机、合绳机岗位噪声强度检测结果超标率100%,拉丝车间噪声检测合格率16.7%。职业卫生管理措施不够完善。结论该公司属于职业病危害较重企业,劳动者有发生职业性慢性铅中毒、职业性化学性灼伤、职业性噪声聋的风险,需采取有效措施进行整改。     

社区1~3岁儿童语言发育与屏幕暴露的相关性调查研究

目的 分析研究社区1~3岁儿童语言发育与屏幕暴露的相关性,为儿童屏幕暴露现状提供改进意见。方法 选取2016年1月-2018年7月于本院儿童保健门诊随访的1~3岁幼儿共827例,男童406例,女童421例,平均年龄为(24.5±5.3)月。采用自制式调查问卷,由本科保健医生指导调查对象的父母或抚养人现场完成,并结合Gesell 婴幼儿发育量表评估调查对象语言发育情况。结果 827例儿童中,93例诊断为语言发育迟缓,734例语言发育正常。两组儿童接触屏幕年龄段、儿童性别、家庭情况、母亲文化程度、父亲文化程度、母亲年龄、屏幕暴露时间、入睡是否规律、接触屏幕时家长陪同和限制屏幕暴露时间差异均有统计学意义(P＜0.05),控制混杂因素影响后多因素Logistic回归分析结果显示,屏幕暴露时间>2 h(OR=1.687,95%CI:1.022~2.236,P<0.001)、接触屏幕时无家长陪同(OR=2.035,95%CI:1.588~2.634,P=0.002)、未限制屏幕暴露时间(OR=1.475,95%CI:1.087~2.156,P=0.035)为语言发育迟缓的重要危险因素。结论 长时间的屏幕暴露会影响家庭语言环境和儿童睡眠,不利于儿童的语言发育,建议家长禁止小于18月的儿童接触屏幕,大于18月的儿童在家长陪同讲解下接触屏幕,时间控制在2 h以内,严格避免睡觉前观看电子屏幕。

Thermal discomfort in healthcare workers during the COVID-19 pandemic

Introduction:Due to the COVID-19 pandemic, healthcare workers are now required to use additional personal protective equipment (PPEs) to protect themselves against the virus. That led to an increased clothing insulation which is negatively affecting the perceived healthcare workers’ thermal sensation.Objectives:While demonstrating through software simulations the potential level of thermal discomfort healthcare workers involved in the COVID-19 emergency can be subjected to, this work aims at identifying measures to improve thermal sensation perception and acceptable thermal conditions for medical personnel.Methods:After having obtained the insulation values of individual clothing used by staff during COVID-19 emergency through the use of a thermal well-being evaluation software, the Fanger indexes (PMV - Predicted Mean Vote and PPD - Predicted Percentage of Dissatisfied) were calculated in order to estimate staff satisfaction to microclimatic conditions.Results:The use of COVID-19 additional PPEs with an air temperature equal to 22 °C (normally considered optimal) brings the PMV index equal to 0.6, which corresponds to 11.8 % being unsatisfied (PPD) due to perceived heat.Discussion:The use of additional protective devices significantly increases the clothing insulation level, facilitating the onset of conditions of thermal discomfort in the health workers. Workers engaged in the execution of nasopharyngeal swabs were most affected by the summer weather conditions and certainly represent the most critical category, for which it would be recommended to implement a higher turnover of service to reduce individual exposure time and consequent discomfort.
