Abstract：
BACKGROUND: Quality of life (QOL) is a vital component in assessing the standard of living for seniors. Hand grip strength (HGS) is a widely used measure to diagnose muscle strength decline that often occurs due to age-related loss of skeletal muscle mass and function. This study focuses on the HGS in predicting the QOL of older adults who are referred to retirement centers in Guilan Province.
METHODS: In 2021, a cross-sectional analytical study was conducted among 115 older adults who were residing in retirement centers located in Guilan Province, Northern Iran. The participants were selected using a two-stage sampling method, where three retirement centers were randomly chosen followed by convenience sampling from each center. The selected retirement centers were situated in Langrod, Sowme\'eh Sara, and Rasht cities in the east, west, and center of the province, respectively. The data were collected through a demographic information questionnaire, QOL scale (CASP-19), and HGS measurement using a dynamometer.
RESULTS: Of the participants, 57.4% were male, 51.3% had middle income, and 96.5% were categorized as young elderly. The mean overall QOL score was found to be 37.026 ± 6.123, while the mean HGS level was 31.74 ± 7.45 and 18.48 ± 5.13 among males and females, respectively. There was a significant association between the level of education and QOL (P = 0.002). Moreover, there was a positive and significant correlation between HGS and QOL (r = 0.54, P = 0.001). The results of the multiple linear regression identified HGS as a predictor of QOL (Adj R2 = 0.44, βHGS = 0.79).
CONCLUSIONS: Given that HGS has been identified as a predictor of QOL in older adults, improving this factor through exercise can lead to enhancement in their QOL. Therefore, regular sports exercises can be recommended as a means of improving HGS and subsequently enhancing the QOL of older adults.

摘要：
背景：生活质量（QOL）是评估老年人生活水平的重要组成部分。手握力（HGS）是一种广泛用于诊断肌肉力量下降的方法，该肌肉力量下降通常是由于与年龄相关的骨骼肌质量和功能丧失而发生的。这项研究的重点是HGS，以预测被转介给桂兰省退休中心的老年人的生活质量。
方法：在2021年，对居住在纪兰省退休中心的115名老年人进行了横断面分析研究。伊朗北部。参与者是使用两阶段抽样方法选择的，其中随机选择三个退休中心，然后从每个中心进行便利采样。选定的退休中心位于Langrod,Sowme\'EhSara,和东部的拉什特城市，西方,和该省的中心，分别。数据是通过人口统计信息问卷收集的，QOL量表（CASP-19），和使用测力计的HGS测量。
结果：在参与者中，57.4%为男性，51.3%的人有中等收入，96.5%被归类为年轻老年人。在男性和女性中，平均总体QOL评分为37.026±6.123，而平均HGS水平为31.74±7.45和18.48±5.13，分别。教育水平与生活质量之间存在显着相关性（P=0.002）。此外，HGS与QOL呈显著正相关(r=0.54,P=0.001)。多元线性回归的结果将HGS确定为QOL的预测因子(调整R2=0.44,βHGS=0.79)。
结论：鉴于HGS已被确定为老年人生活质量的预测因子，通过锻炼改善这一因素可以提高他们的生活质量。因此,建议定期进行体育锻炼，以改善HGS并随后提高老年人的QOL。
