Analysis Method and Experiment on the Influence of Hard Bottom Layer Contour on Agricultural Machinery Motion Position and Posture Changes

Background and objective. Low back pain (LBP) is one of the most prevalent musculoskeletal disorders globally, significantly impacting quality of life across diverse populations. Despite its association with middle-aged and older populations, evidence indicates that LBP is increasingly prevalent among younger age groups. Health science students are considered a potential risk factor for LBP; however, longitudinal studies are scarce. This study aims to determine the risk factors for LBP among health science students over a 2-year follow-up. Methods. One hundred ninety-seven of the third-class health science students (Nursing, Physiotherapy, Medical laboratory science, and Emergency Medical services) were contacted (May 2024). A self-administered modified version of the Standardized Nordic Questionnaire, and data about sedentary and physical activity behavior, as well as LBP/ or stress scores, were recorded. Results. A total of 172/197 (87.3%) respondents completed the questionnaire in the 2-year follow-up. Mean age of 25 ±3.5 (years) and body mass index (BMI) value of 23.5 ± 4.3 (kg/m2). About 49% (n= 84) and 20% (n=34) of the participants had 1-month LBP and functional disability, respectively. No association was found between health science programs and the presence of 1-month LBP (χ²= 0.55, P>0.05). The logistic regression analyses found that males had a significantly lower likelihood of having LBP (OR 0.25, P = 0.03). Conclusions. This study shows a high prevalence of 1-month LBP (48.8%) among health science students at Zefat Academic College. LBP was over time, gender-dependent, and health science-independent.
