基于Pearson相关系数中国空巢老年人生活质量与社会支持相关性研究的Meta分析

Meta analysis on correlation between living quality of Chinese empty-nest elderly and social support based on Pearson correlation coefficient

目的采用Meta分析的方法,评价基于Pearson和spearson相关系数的空巢老年人生活质量与其各因素相关性。方法利用网络数据库检索Cochrane Library、PubMed、Medline、Embase、Springerlink、中国生物医学文献数据库、中国知网全文数据库、万方数据库和中国科技期刊数据库,检索时限至2016年7月,查找关于空巢老年人生活质量与社会支持相关性的文献。按照纳入排除标准筛选文献、提取资料并评价纳入研究的质量后,采用STATA11.0软件进行Meta分析。结果共纳入5篇文献,文献质量总体较好。总样本量为2 485名,男1 201名,女1 284名。Meta分析显示,社会支持与生活质量合并相关系数及95%CI为0.287(0.252,0.329);社会支持利用度与生活质量合并相关系数及95%CI为0.232(0.191,0.274);主观支持与生活质量合并相关系数及95%CI为0.260(0.224,0.298);客观支持与生活质量合并相关系数及95%CI为0.139(0.101,0.179),合并后相关系数以社会支持最高。空巢老年人生活质量与社会支持总分随着样本量逐渐增加,相关性随之减小。随机抽样方法测出相关系数高于非随机抽样方法测出的结果。南方空巢老年人生活质量与社会支持相关系数高于北方。结论中国空巢老年人生活质量与社会支持存在相关,主要受主观支持、对支持利用度等因素的影响。

Objective To adopt the meta analysis to evaluate the living quality of empty-nest elderly based on Pearson and Spearson correlation coefficients. Methods The databases including Cochmne library, PubMed, PIDQuest, Medline, Springerlink, CMB,CNKI, VIP and WanFang Data were retrieved by using the network databases with the retrieval time limit until July 2016. The literatures on the correlation between the social support and living quality of Chinese empty-nest elderly were searched. The in- cluded studies were screened according to the inclusion and exclusion criteria. After extracting data and appraising the quality of the included studies,the meta analysis was conducted by using STATAll. 0 software. Results Five articles were included. The litera- ture quality was good as a whole. The total sample amounts were 2 485 subjects,including 1 201 males and 1 284 females. The meta analysis showed that merge correlation coefficient of social support and living quality,and 95M confidence interval（CI） were 0. 287 （0. 252,0. 329） ;which of social support utilization degree and living quality were 0. 232 （0.191,0. 274） ;which of subjective support and living quality were 0. 260 （0. 224,0.298）, which of objective support and living quality were 0. 139 （0. 101,0. 179）, after merge, the correlation coefficient of social support was highest. The living quality and social support total score were increased with the samples amounts increase, and the correlation was accordingly decreased. The correlation coefficient measured by random sample method was higher than that measured by the non-random sample method. The correlation coefficient and social support in southern empty-nest elderly was higher than that of northern empty-nest elderly. Conclusion The living quality in Chinese empty-nest elder- ly has a correlation with the social support,which is mainly affected by subjective support and support utilization degree.
