To explore the relationship between hand grip strength (HGS) and blood pressure in physically disabled individuals over 50 years old.
The research adopts a cross-sectional survey, and the data comes from the "2022-2023 Physical Health Monitoring and Scientific and Technological Services for Physical Disabilities" jointly carried out by Beijing Sport University and China Disabled Sports Management Center. Select physically disabled individuals over 50 years old and collect physical fitness measurement data. HGS was measured and adjusted based on body weight and waist circumference, with standard normal conversion. The relationship between HGS and blood pressure was analyzed using multiple linear regression, and further logistic regression was used to analyze the relationship between standard HGS and the risk of abnormal blood pressure.
695 disabled individuals participated in the experiment, including 402 males (57.84%) and 293 females (42.16%). Multiple linear regression analysis found that for each standard deviation increase in the standardized Z-value of relative HGS, the systolic and diastolic blood pressure of male individuals decreased by 2.391 mmHg (P = 0.008) and 1.229 mmHg (P = 0.025); decreased by 2.336 mmHg (P = 0.026) and 1.585 mmHg (P = 0.008), respectively, for female. The increase in HGS reduced the risk of hypertension in physical disabilities in males [OR = 0.820 95%CIs (0.670, 0.952)] (P = 0.003) and females [OR = 0.735 95%CIs (0.472, 0.986)] (P = 0.007).
The HGS of middle-aged and elderly physically disabled individuals negatively correlates with blood pressure, indicating the importance of increasing muscle strength (HGS) in preventing blood pressure.
探讨 50 岁以上肢体残疾人群握力（HGS）与血压的关系。
采用横断面调查研究，数据来源于北京体育大学和中国残疾人体育运动管理中心联合开展的“2022-2023 年肢体残疾人身体状况监测与科技服务”。选择 50 岁以上肢体残疾人，采集身体基本素质测试数据。测量握力，根据体重和腰围进行调整，进行标准正态化转换。采用多元线性回归分析 HGS 与血压的关系，进一步采用 logistic 回归分析标准 HGS 与血压异常风险的关系。
共 695 名残疾人士参与实验，其中男性 402 人（57.84%），女性 293 人（42.16%）。多元线性回归分析发现，男性个体相对 HGS 的标准化 Z 值每增加一个标准差，收缩压和舒张压分别降低 2.391mmHg（P=0.008）和 1.229mmHg（P=0.025）；女性个体收缩压和舒张压分别降低 2.336mmHg（P=0.026）和 1.585mmHg（P=0.008）。握力增加可降低男性肢体残疾人群高血压风险[OR=0.820 95%CIs（0.670，0.952）]（P=0.003）和女性[OR=0.735 95%CIs（0.472，0.986）]（P=0.007）。
中老年肢体残疾人群的 HGS 与血压呈负相关，提示增强肌肉力量（HGS）对预防血压升高的重要性。
