Improving the physical, psychological, and social factors in the elderly significantly increases the QoL among them. This study aims to identify the crucial factors for predicting QoL among the elderly using statistical methods.
In this study, 980 samples related to the elderly with favorable and unfavorable QoL were investigated. The elderly's QoL was investigated using a qualitative and self-assessment questionnaire that measured the QoL among them by five Likert spectrum and independent factors. The Chi-square test and eta coefficient were used to determine the relationship between each predicting factor of the elderly's QoL in SPSS V 25 software. Finally, we used the Enter and Forward LR methods to determine the correlation of influential factors in the presence of other variables.
The study showed that 20 variables gained a significant relationship with the quality of life of the elderly at < 0.05. The study results showed that the degree of dependence ( = 0.03), diabetes mellitus ( = 0.03), formal and informal social relationships ( = 0.01 and = 0.02), ability to play an emotional role ( = 0.03), physical performance ( = 0.01), heart diseases and arterial blood pressure ( = 0.02), and cancer ( = 0.01) have favorable predictive power in predicting the QoL among the elderly.
Attempts to identify and modify the important factors affecting the elderly's QoL have a significant role in improving the QoL and life satisfaction in this age group people. This study showed that the statistical methods have a pleasant capability to discover the factors associated with the elderly's QoL with high performance in this regard.
改善老年人的身体、心理和社会因素可显著提高其生活质量。本研究旨在运用统计方法确定预测老年人生活质量的关键因素。
本研究调查了980例生活质量良好和不佳的老年人样本。使用定性和自我评估问卷对老年人的生活质量进行调查，该问卷通过五个李克特量表和独立因素来衡量他们的生活质量。在SPSS V 25软件中，使用卡方检验和eta系数来确定老年人生活质量各预测因素之间的关系。最后，我们使用进入法和向前似然比法来确定在存在其他变量的情况下影响因素的相关性。
研究表明，20个变量与老年人的生活质量在<0.05水平上存在显著关系。研究结果显示，依赖程度（=0.03）、糖尿病（=0.03）、正式和非正式社会关系（=0.01和=0.02）、发挥情感作用的能力（=0.03）、身体机能（=0.01）、心脏病和动脉血压（=0.02）以及癌症（=0.01）在预测老年人生活质量方面具有良好的预测能力。
试图识别和改变影响老年人生活质量的重要因素，对提高该年龄组人群的生活质量和生活满意度具有重要作用。本研究表明，统计方法在发现与老年人生活质量相关的因素方面具有出色的能力，在这方面表现高效。
