A cross-sectional study evaluating grip strength and associated factors in Turkish nurses and nursing students.

Background: Grip strength is an important indicator of muscle strength. Nursing job demands physical power, which is related to their muscle strength. However, studies on nurses' grip strength remains lacking.

Objective: This study aims to examine the differences in grip strength between staff nurses and nursing students and to identify factors associated with grip strength in nursing sample.

Method: This study was designed as descriptive and analytical. Data collected from nursing students and staff nurses in Turkiye, from May 1 to September 30, 2022. A total of 200 staff nurses and 200 nursing students participated. Data tool included a participant information form, the Perceived Stress Scale-4 (PSS-4), and the Nordic Musculoskeletal Questionnaire (NMQ). Moreover, researchers assessed the anthropometric measurements using the same scale and grip strength using a digital hand dynamometer.

Results: There was no significant difference in grip strength of staff and student nurses. 48.8% of participants met or exceeded Turkish normative values. 79.5% of staff nurses and 66.0% of nursing students reported musculoskeletal issues in the last 12 months. Height, waist-to-hip ratio, and neck circumference was found to be significant predictors of grip strength, explaining 57% of the variance.

Conclusion: Grip strength was similar between staff nurses and nursing students, despite differences in age, BMI, and musculoskeletal issues. Height, waist-to-hip ratio, and neck circumference are key predictors of grip strength in this Turkish nursing sample. Understanding the factors influencing grip strength can help in designing targeted interventions to maintain and improve muscle strength in nursing professionals.
