网络成瘾和睡眠时长在青少年受校园欺凌与抑郁间的链式中介作用

目的 探索青少年网络成瘾和睡眠时长在受校园欺凌与抑郁关系之间的中介作用,为青少年抑郁的预防干预提供依据。 方法 使用青少年健康相关危险行为问卷及CES - D抑郁量表,采用多阶段整群抽样法抽取徐州市4 190名青少年进行问卷调查。结果 在控制人口学等变量后,受校园欺凌、网络成瘾、睡眠时长对抑郁均有预测作用（r = 0.283,P＜0.01;r = 0.331,P＜0.01;r = - 0.184,P＜0.01）。路径分析表明,网络成瘾在受校园欺凌和青少年抑郁之间起中介作用;网络成瘾和睡眠时长在受校园欺凌和青少年抑郁间起链式中介作用。结论 受校园欺凌不仅直接影响青少年抑郁,还通过网络成瘾和睡眠时长的链式中介作用间接影响青少年抑郁。可通过减少青少年网络使用和提高睡眠时长来降低受校园欺凌对青少年抑郁的影响。

Adverse Childhood Experiences and Suicidal Behaviors Among Youth: The Buffering Influence of Family Communication and School Connectedness

PurposeThe main objectives of this study were to determine (1) whether family communication and school connectedness offer protection against suicidal behaviors in the presence of adverse childhood experiences (ACEs; direct protective effect) and (2) whether family communication or school connectedness buffer the association between ACEs and suicidal behaviors (interacting protective effect) on the multiplicative and additive scales.MethodsData were obtained from a western state's 2019 Youth Risk Behavior Survey that included 5,341 middle school and 4,980 high school participants. Generalized linear models were used to estimate whether family communication and school connectedness offered direct protection against suicidal behaviors or buffered the association between ACEs and suicidal behaviors using adjusted prevalence ratios and corresponding 95% confidence intervals.ResultsFamily communication and school connectedness offered direct protection against suicidal behaviors in the presence of ACEs (a 1-unit higher score was associated with a 32%–42% lower prevalence of suicidal behaviors for middle school youth and a 27%–39% lower prevalence of suicidal behaviors for high school youth). There was evidence that family communication and school connectedness buffered the association between ACEs and suicidal behaviors on the multiplicative scale.ConclusionsThe findings provide support for the development and implementation of interventions that build family communication and school connectedness to reduce suicidal behaviors. Furthermore, screening for trauma and suicidal behaviors is warranted.     

Mapa de las políticas nutricionales escolares en España

ObjectiveTo systematically describe the school nutritional policies of the 17 autonomous communities of Spain.MethodThrough a search of bibliographic databases, web pages and other official information systems, 183 documents of interest were identified. Information was systematically collected with the SNIPE (school nutrition index of programme effectiveness) questionnaire, adapted to Spain, and validated by reference staff of the regional government's health and education ministries.ResultsThe main objective of the policies is to prevent obesity and improve the nutrition of schoolchildren. The 17 autonomous communities cover the school canteen service, 11 cafeteria and vending machines, and 9 the breakfast service. All communities use the Consensus Document on School Food as a reference for the content of the menu and the nutritional quality of the products offered at the school; however, only 4 of them have regulated these aspects. The evaluation of policy objectives ranges from 58.8% of the autonomous communities for food supply to 5.9% for rotation and menu quality.ConclusionAlthough all the autonomous communities have standards for the school menu, the standards for the rest of the food supply vary across them; also, evaluation of objectives is scarce and only 4 communities have approved mandatory regulations. Nutritional standards should be reviewed according to current scientific knowledge and enacted by law, in compliance with the current legislation (Act 17/2011).     

豫南农村地区青少年校园暴力状况及其与性取向的关联分析

目的 了解豫南农村地区青少年校园暴力状况及性取向对其的影响,为豫南农村地区青少年校园暴力和身心健康干预提供借鉴。方法 采用分层整群抽样的方法2019年在豫南农村地区对4214名青少年进行问卷调查。结果 豫南农村地区青少年遭受校园暴力的比例为50.65%。在不同年级、性别、父亲学历、母亲学历、学习成绩、性取向方面学生遭受校园暴力的比例相比较,差异均有统计学意义（〖XC小五号.EPS;P〗值分别为21.56、101.65、8.78、9.34、11.94、18.54,P＜0.01）。多因素logistic回归分析表明,同性恋（OR值为1.52,95%CI为1.01~2.28）、双性恋（OR值为1.69,95%CI为1.27~2.22）与青少年遭受校园暴力呈现正相关关系（P＜0.05或0.01）。结论 豫南农村地区青少年校园暴力状况不容乐观,应采取有效干预措施进行暴力行为的干预和引导,同时教导青少年理性面对同性恋或双性恋群体,减少或避免校园暴力的发生。     

“医教协同”模式下专业学位硕士研究生压力感知及学术能力提升需求调查

目的 对医学专硕学术科研水平的影响因素进行调研与分析,以期为提高其学术科研水平提供参考和借鉴。方法 选取某医院正在参与住院医师规范化培训的医学专硕作为研究对象,采用问卷调查的方式对其学术水平影响因素进行调研。结果 研究生对于提升自身学术科研水平有较大的需求,且普遍存在学术科研方面的压力,随着年级的上升其压力亦明显呈上升趋势（线性χ2 = 21.624,P＜0.001）。本科的知识储备、个人英语水平、兴趣爱好对其学术科研水平均有一定影响。结论 改革创新研究生学术科研水平的培养是各大高等医学院校亟待解决的问题,研究生学术科研水平的提高,需要学生、导师与高校三者进行有机结合通力协作。
