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).     

Early childhood exposure to intimate partner violence and teen depression symptoms in the U.S.

Among the various negative outcomes of intimate partner violence (IPV) exposure to children, depression symptoms are worthy of attention given the effects on well-being and long-term achievement. This study examined the effects of early childhood exposure to IPV between ages 1 and 3 on depression symptoms at age 15 and investigated whether maternal physical punishment at age 5 and peer bullying victimisation at age 9 affected the association. Data came from five waves of the Fragile Families and Child Wellbeing Study. The study was based on 20 U.S. cities with populations of over 200,000 people. The most recent wave of data collection occurs during the period between 2014 and 2017. The final analytic sample was 1,690 children. Structural equation modeling was utilised to examine the effects of exposure to IPV on physical punishment, bullying victimisation, and depression symptoms. Early exposure to IPV was associated with experiencing physical punishment at Year 5, which subsequently increased peer bullying victimisation at Year 9 and then depression symptoms at Year 15. Early exposure to IPV had a direct effect on depression symptoms at Year 15. Early exposure to IPV also had indirect effects on Year 15 depression symptoms through its effects on physical punishment and bullying victimisation. The total standardised effect of early exposure on depression symptoms was 0.06. Consistent with trauma theory and the ecobiodevelopmental framework, the results indicate that exposure to IPV appeared to have a long-term effect on children, manifested in teen depression symptoms.     

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。
