Background and objective: The present study assesses the relationship between hyperuricemia and pulse pressure (PP) in non-diabetic Korean adults. Material and methods: Data from 5122 subjects (2251 men and 2871 women) in the seventh Korean National Health and Nutrition Examination Survey (KNHANES VII-2, 2017) were analyzed. Results: Systolic blood pressure (SBP) and PP were significant factors determining the odds ratios (ORs) for hyperuricemia (uric acid ≥7.0 mg/dL in men or ≥6.0 mg/dL in women) in men and the overall population. In women, SBP, diastolic blood pressure (DBP), and PP were not significant factors determining the OR for hyperuricemia. After adjusting for related variables, the OR of hyperuricemia was significantly higher in the high PP group (PP >60.0 mmHg) for men (OR, 1.760; 95% confidence interval [CI], 1.152--2.688) and the overall population (OR, 1.557; 95% CI, 1.132--2.140) compared with the normal PP group, but this trend was not seen in women (OR, 1.060; 95% CI, 0.646--1.740). Conclusions: Hyperuricemia was positively associated with PP in non-diabetic Korean men but not in women.
Purpose: This study examined the effects of a paraffin treatment with exercise on the muscle strength and fatigue of the hand according to the use of smartphones. Methods: The measurement subjects were 30 healthy males in their 20s who were divided randomly into the control and paraffin treatment groups. A typing exercise using a smartphone was performed. The pinch grip force was measured to evaluate the muscle strength of the thumb, and muscle fatigue analysis using electromyography was performed to analyze muscle fatigue. Results: The functional changes to the arm and the fatigue of the hand through the use of a smartphone were examined to determine the effects of the paraffin treatment. The dominant hand-pinch grip force test did not show a significant difference, but the non-dominant hand-pinch grip force test showed a significant difference between the groups (p=0.030). In the dominant hand fatigue test, there was a significant difference between the groups (p=0.037). In the non-dominant hand, there was a significant difference between time (p=0.012) and the groups (p<0.001). Conclusion: The effects of paraffin intervention on the hand muscle strength and fatigue due to repeated use of the smartphone were confirmed. These results can be used as a basis for clinical use and can be a guide for the correct use of smartphones, which are essential in modern life.
