Abstract
Background and Aim: Low-grade systemic inflammation, sedentary lifestyle, and vitamin D deficiency are considered risk factors for developing non-specific low back pain. The aim of this study was to investigate the effect of selective lumbar stabilization exercises with vitamin D intake on the level of hypersensitive C-reactive protein (hs-CRP) and 25-hydroxy vitamin D levels in women with chronic non-specific low back pain.
Materials and Methods: In this semi-experimental study with pretest–posttest design, 48 women with chronic low back pain were initially selected by available sampling method and then randomly divided into control, exercise, vitamin D and combined groups. Lumbar stabilization exercises were performed at different levels for 8 weeks. The vitamin D and combined groups received 50,000 IU vitamin D weekly. Data were analyzed using paired t-test, ANOVA and Kruskal-Wallis tests with a significant level of less than 0.05. 
Results: 25.64% and 74.26% of the subjects had insufficient levels of vitamin D (20-29 ng/ml) and vitamin D deficiency (less than 20 ng/ml), respectively. 8 weeks of lumbar stabilization exercises, vitamin D consumption, and the combined intervention decreased hs-CRP and increased 25-hydroxyvitamin D. In addition, the combined intervention had a stronger effect on lowering hs-CRP levels compared to the other two interventions. The effect of vitamin D intake and combined intervention on improving vitamin D status was greater compared to lumbar stabilization exercises.
Conclusion: It seems that lumbar stabilization exercises, vitamin D intake, and combined interventions can improve low-grade systemic inflammation in people with low back pain and low vitamin D levels by lowering hs-CRP and positively regulating 25-hydroxyvitamin D, but combined intervention is associated with greater effectiveness in reducing hs-CRP.

Abstract
Background and Aim: Low back pain (LBP) is one of the most common musculoskeletal disorders among operating room nurses, and numerous studies have well explained its causes and factors. However, studies focusing on the characteristics and dimensions of low back pain and its relationship with influencing factors have not been conducted. Therefore, the aim of this study was to investigate the prevalence of the type of LBP, duration of back pain, and severity of back pain, and their relationship with the demographic characteristics of operating room nurses.
Materials and Methods: This cross-sectional study was conducted on 350 operating room nurses at Ahvaz teaching hospitals in Iran in 2023. Data were collected using a questionnaire that included demographic information and LBP characteristics. Data were analyzed using IBM SPSS.
Results: 64.8% of the subjects were female, 63.5% were married, and their mean age was 33.83±7.02 years. The prevalence of LBP among operating room nurses was 74.3%. In 60.7% of participant who have LBP, the first experience of back pain was in the past 5 years. The most common diagnosis of LBP was muscular disorders (29.9%). Also, 57.3% of them had pain only in the lower back and 42.7% of them had LBP radiating to the legs. We found no statistically significant relationship between the duration and severity of LBP and demographic characteristics (P<0.05). A statistically significant relationship was found between the type of LBP and gender and level of education, as well as between the duration of LBP and severity of LBP (P<0.05).
Conclusion: The findings of this study showed a high prevalence of LBP among operating room nurses, and differences in the type of LBP were observed based on gender and educational level, which may be attributed to individual factors. Additionally, the significant relationship between the duration of LBP and its severity may indicate the effect of the long duration of LBP on its severity, which suggests that providing counseling and treatment programs for nurses who are in the early stages of LBP.
