Objectives:
To explore the relationship between hand grip strength (HGS) and blood pressure in physically disabled individuals over 50 years old.
Methods:
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.
Results:
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).
Conclusion:
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.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
