目的分析养老机构内老年人生活满意度情况及其影响因素。方法采用整群随机抽样方法,在厦门市13家养老机构抽取230名老年人进行调查,了解养老机构老年人生活满意度状况,并利用主成分logistic回归分析其影响因素。结果获得有效问卷204份。调查显示厦门市养老机构内老年人生活满意度普遍较高。女性、年龄小、文化程度高、日常生活能力和健康自评效果好、与亲人相见频数高、对机构支持信任度高的老年人生活满意度相对较高。结论为提高养老机构老年人生活满意度,积极应对老龄化,老人应理性对待自身健康状况,积极面对生活;亲属应多去看望,给予老人更大的关爱和心理慰藉;养老机构也应大力提高其服务质量,丰富服务内容,给予老年人充分的物质、精神支持。国家自然科学基金(71403229,81573257

基于Andersen模型的“医养结合“型机构养老需求的影响因素研究

目的了解老年人对\"医养结合\"型机构养老需求的现状及其影响因素,为构建多层级、持续性\"医养结合\"长期照护服务体系提供循证依据。方法采用多阶段抽样方法,抽取厦门市6个区,16个街道/镇,44个社区,3260名60周岁及以上老年人进行面对面问卷调查。基于Andersen理论模型,采用卡方检验分析人群分布差异,采用二元logistic回归分析方法从倾向性因素、使能因素、需要因素等方面分析老年人对\"医养结合\"型机构养老需求的影响因素。结果大多数老年人选择传统的居家养老(82.01%),仅有12.89%的老年人表示希望入住\"医养结合\"型养老机构。倾向性因素中,年龄越大、文化水平越高、居住在农村的老年人更倾向于选择医养结合养老模式,OR值均大于1(P<0.05);使能因素中,在婚、主要由配偶照护、经济状况越好的老年人倾向于医养结合式养老,OR值均大于1(P<0.01);需要因素中,老年人自理情况越差越倾向于入住\"医养结合\"型养老机构(P<0.01)。使能因素对模型的贡献度最大,对医养结合养老需求的影响最大。结论厦门市老年人对于\"医养结合\"机构养老模式的需求高于一般的机构养老需求。\"...国家自然科学基金项目(81573257);;\n福建省自然科学基金(2017J01133

Functional groups of benthic macrofauna in the 14th Yong intertidal zone of Nansha,Guangzhou

大型底栖动物根据食性可分为浮游生物食者(planktophagous,Pl)、植食者(phytophagous,Ph)、肉食者(carnivorous,C)、杂食者(omnivorous,O)和碎屑食者(detritivorous,D)五个功能群。本文根据2007–2008年度和2013–2014年度在茳芏(Cyperus malaccensis)、海桑(Sonneratia caseolaris)2种生境调查获得的各4个季度的大型底栖动物数据,分析了广州南沙十四涌潮间带大型底栖动物功能群的生境差异、季节变化和年际变化。2007–2008年度采集到26种大型底栖动物,低于2013–2014年度的36种。无论是2007–2008年度还是2013–2014年度,茳芏、海桑生境的大型底栖动物均以植食者的栖息密度和生物量最高,碎屑食者的栖息密度和生物量最低。生境比较得出,茳芏生境大型底栖动物浮游生物食者(Pl)的丰富度指数(d)、均匀度指数(J)和多样性指数(H')均高于海桑生境。年度比较得出,在茳芏和海桑生境,2013–2014年度浮游生物食者的丰富度指数、均匀度指数和多样性指数均高于2007–2008年度,这是因为2013–2014年度采集到红树蚬(Gelonia coaxans)和彩虹明樱蛤(Morerlla iridescens)等,而2007–2008年度没有采集到。Benthic macrofauna were classified into 5 functional groups,i.e.planktophagous(Pl),phytophagous(Ph),carnivorous(C),omnivorous(O) and detritivorous(D).The biotope difference,seasonal and annual variations of functional group of benthic macrofauna in the intertidal zone of the 14 th Yong of Nansha,Guangzhou were analyzed in this study according to the four seasonal data of benthic macrofauna collected in two biotopes(Cyperus malaccensis and Sonneratia caseolaris) in 2007–2008 and 2013–2014.A total of 26 species were recorded in 2007–2008,which was lower than 36 species in 2013–2014.Both in 2007–2008 and 2013–2014,phytophagous group showed the highest value while detritivorous group shared the lowest one in density and biomass.Habitat comparison showed that the abundance index(d),evenness index(J) and diversity index(H') of planktophagous group in Cyperus malaccensis habitat were all higher than those in Sonneratia caseolaris habitat.Annual comparison showed that the abundance index,evenness index and diversity index of planktophagous group in 2013–2014 were all higher than those in 2007 –2008 both in Cyperus malaccensis and Sonneratia caseolaris habitats because the planktophagous such as Gelonia coaxans and Morerlla iridescens and so on were collected in 2013–2014 but they were not found in 2007–2008.国家自然科学基金(41176089和41376113
