我校大学生的营养状况调查与对策研究

对三峡大学的部分学生的营养状况、营养知识和饮食行为进行问卷调查,结果表明:大学生营养不良程度较轻,其饮食的月消费水平大都在200~400元之间,但营养知识的掌握情况一般,同时存在一些不良的饮食行为,因此,学校应强化营养知识教育,在加强后勤管理与改革的同时,把提高学生食堂供餐的营养质量作为一项重要的工作来抓。     

Physical exercise,nutrition and hormones: three pillars to fight sarcopenia

Background: Sarcopenia is a pathophysiological condition diffused in elderly people; it represents a social issue due to the longer life expectancy and the growing aging population. It affects negatively quality of life and it represents a risk factor for other pathologies, such as diabetes, cardiovascular disease, and obesity. No silver bullet exists to hinder sarcopenia, but it may be counteracted by physical exercise, nutrition, and a proper endocrine milieu. Indeed, we aim to analyze the scientific literature to give to clinician effective advices to counteract sarcopenia.

Main text: Physical exercise, proper nutrition, optimized hormonal homeostasis represent the three pillars to fight sarcopenia. Physical exercise represents the most effective remedy to face sarcopenia, in particular if it is combined with a proper diet and with an adequate endocrine milieu. Consistency in training, adequate daily protein intake and eugonadism seems to be the keys to fight sarcopenia. The combination of these three pillars might act synergistically.

Conclusions: Optimization of these factors may increase their efficiency; however, scientific data may be sometimes confusing so far. Therefore, we aim to give practical advices to clinician to identify and to highlight the most important aspects in each of these three factors that should be addressed.     

Caloric restriction minimizes aging effects on the femoral medial condyle

This study aimed to analyze the effects of caloric restriction on aged femoral articular cartilage of Wistar rats. Three groups of eight animals each were considered: young (YC) and old (OC) control groups fed with a normal diet and old caloric restriction group (OCR) composed of 18-month-old animals fed with a 31% less caloric diet from 6-months of age. Articular cartilage was studied through morphometry and immunohistochemistry. Body mass was 12% less in the OCR group than in the OC group. The articular cartilage from OC rats show thinner medial condyles, fewer chondrocytes, smaller chondrocytes nuclear volume and, in both condyles, a predominance of collagen type II and less collagen density compared to both YC and OCR groups (p?p?相似文献   

大学教学价值取向:历史与现实

从影响当前大学教学方方面面的价值取向看,大学教学要坚守古代的"理智培育"价值取向,这是大学教学永葆魅力的根源所在.同时,大学教学要张扬现代的"技术获取"价值取向,这是作为生活世界现象的大学教学的重要使命之一.第三,大学教学要倡导后现代的"欲望释放"价值取向,这是大学教学充满生机与活力的保证.因此,大学教学价值取向并非还原为欲、技、道中的某一维,而是这三者的有机统一.     

The nutrition-related information seeking behaviours and attitudes of pregnant women with a high BMI: A qualitative study

BackgroundThe prevalence of high body mass index is increasing amongst women of child bearing age. High maternal body mass index has ramifications for both mother and baby including increased health risks from gestational diabetes mellitus, caesarean section and stillbirth. Despite the increasing prevalence of high maternal body mass index little is known of the experiences of these women regarding nutrition information access and use during the antenatal period.MethodsA qualitative study using individual interviews was undertaken at a tertiary hospital in south-eastern Australia. Twenty-Eight women with a body mass index ≥30 kg/m² participated. Interviews were audio recorded, transcribed, cross-checked for consistency and entered into a word processing document for further scrutiny. Data was analysed using interpretative phenomenological analysis (IPA). In any phenomenological study the researcher’s objective is to elicit the participant’s views on their lived experiences.FindingsThree major themes emerged: (1) Nutrition-related information attainment; (2) Nutrition-related information management; (3) Nutrition-related information needs and wants.ConclusionThe findings from this study may assist the future development and dissemination of nutrition-related information for pregnant women with a high body mass index. Women want more individualised support regarding nutritional requirements during pregnancy.     

蒙台梭利儿童饮食生活教育的扎根研究

当今国内对蒙台梭利的研究更多体现在宏观层面,而专门对饮食生活教育的研究较少受到关注,特别是缺乏“深描”性质的质化研究。鉴于此,研究者以6部蒙台梭利教育论著作为“访谈”对象,采用非交互性资料收集方式,深度挖掘文献资源,通过三级编码发展出蒙氏儿童饮食生活教育的扎根理论。研究发现,蒙氏儿童饮食生活教育思想体系包括饮食营养的价值追求、食物的来源及处理、儿童饮食行为的发展、饮食生活教育过程等4个理论构念,其中包含健康功能、健康权利、健康卫生、食品制作、食物选择、饮食文化、发展需求、发展阶段、营养因素、行为练习、饮食调控、教育误区等12个触发式概念。蒙氏饮食生活教育也是一个调节儿童与食物主客交互并具有积极价值追求的实践体系,对于当今儿童健康教育现实具有极强的指导意义。     

Toward total student health: A qualitative pilot study

Objective: Colleges should aim to cultivate healthy behaviors among students by addressing alterations in wellness students view as important. The purpose of this study was to determine the self-perceived wellness-related concerns and behaviors of college students. Participants: Thirty-seven undergraduate students participated in this study between January and March 2017. Methods: Focus groups served as a data collection method. Groups were recorded and transcribed verbatim. Directed and conventional approaches to data analyses were employed. Results: Participants expressed concern regarding four campus wellness topics: nutrition, economics, mental health, and campus safety. Participants offered solutions for improving campus wellness, representing a fifth theme. Conclusions: Health concerns for college students and realistic solutions to address concerns were identified across focus groups. Overall, students cared about their own health, as well as the well-being of other students. Future directions include conducting a Web-based survey among students to assess prevalence and impact of select health and wellness topics.     

All for one or one for all? Authorship and the cross-sectoral valuation of credit in nutrition science

The passionate pursuit of authorships is fuelled by the value they represent to scholars and scientists. This article asks how this value differs across scientists and how these different processes of valuation inform authorship articulation, strategies, and publication behavior in general. Drawing from a qualitative analysis of authorship practices among nutrition scientists employed at universities, contract research organizations, and in food industry, I argue that two different modi operandi emerge when it comes to authorship. These different ways of working produce different collaborative approaches, different credit distribution strategies amongst collaborators, and different value placed upon (the pursuit of) authorship. These different valuation processes are neither explicit nor recognizable to those reading (and judging) author lists. As a consequence, in the politics of authorship, the names standing atop a scientific publication in nutrition science represent different types of value to both the individuals and employing organizations.     

营养人类学研究简述

营养人类学(Nutritional Anthropology)是营养科学与人类学结合形成的一门分支交叉学科,探究文化、营养与健康之间的关系.在西方,营养人类学已经发展出较为成熟的学科理论体系且取得了丰富的研究成果,但在中国人类学界对这一分支学科的关注并不多.本文从人类学的角度梳理了"食物"与"营养"之间的关系,介绍了营养人类学的学科起源、关键概念以及主要研究领域.
