    Aims: Commitment to a plan of action key factors is critical for stretching exercise predicting. However, commitment to a plan of action in stretching exercise across the throughout working conditions is far difficult in Iran; there is no measurement to evaluate commitment to a plan of action among workplace office employees. This study aimed at investigating the short form of confirmatory factor analysis commitment to a plan of action scale for stretching exercise predicting among based on health promotion model (HPM). Materials & Methods: Using multistage cluster sampling, 385 office employees from Shahid Beheshti University of Medical Sciences of Iran were selected through on a short form of commitment to a plan of action Scale. Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA) and Cronbach’s alpha were also used. Findings: The mean age of the office employees was 39.4±7.76 years. CVI and CVR of each question were >0.7. The result of EFA confirmed one factor or component with the main component technique (commitment to a plan of action) with 71.8% cumulative variance and KMO was 87.2% (p<0.001). This was the good fit index in CFA. The reliability was also explanatory. In the area of CFA, the result showed REMSEA=0.046, GFI=0.907, AGFI=0.814, confirmed with Cronbach’s alpha (α=85.8%) and [ICC =0.74; 95% CI (0.62, 0.74)]. Conclusion: This study approved the short form of commitment to a plan of action scale for stretching exercise. However, more advice is provided to ensure a reliable and valid tool for realizing stretching exercise behaviors.

    Aims
    The sitting posture and its related problems are of high importance. The current research was conducted with the aim of design and evaluation of a measurement tool for sitting situation, using validity and reliability.
    Instruments and
    Methods
    In this semi-experimental (field trial) study, a number of questions about knowledge, attitude, and behavior were designed and content validity and face validity were utilized to assess the validity. Then, questionnaire was given to 10 specialists in health education, physiotherapists, and ergonomists. Moreover, Content Validity Ratio (CVR) and Content Validity Index (CVI) were calculated to determine content validity, and for reliability assessment, two criteria were used, including internal consistency through Cronbach's alpha and test-retest through Intra-class Correlation Coefficient (ICC) and Pearson correlation coefficient. Consequently, 30 students were enrolled in the study. The data were analyzed by SPSS 22 software.
    Findings: Firstly, of all 29 questions in terms of knowledge, attitude, and behavior, 23 items remained with CVR higher than 0.6 and CVI tables were higher than 0.7. From 23 items referring to the 3 mentioned spectra, 12 questions were in the field of knowledge, 6 questions were in the field of attitude, and 5 questions were in the field of behavior. Then, the Cronbach's alpha coefficient was 0.87, the ICC was 0.983, and Pearson correlation coefficient was 0.966 (p<0.001).
    Conclusion
    The designed questionnaire can appropriately examine sitting situation in terms of the knowledge, attitude, and behavior; therefore, it is an excellent tool for measuring these characteristics owing to satisfactory validity and reliability.

    Aims: one of the most common musculoskeletal disorders among farmers is low back pain. The aim of this study was to investigate the effect of corrective exercise training on low back pain disorder among farmers. Materials & Methods: This research is a semi-experimental study that was conducted on farmers in Aq-Qala, Golestan Province, Iran in 2017. The statistical population of this study was all farmers in the central part of the city of Aq-Qala. The sample consisted of 100 farmers in the central city of Agh-Ghala were randomly divided into two groups, intervention (n=50) and control (n=50) groups. The instrument of research was Nordic questionnaire. The intervention group participated in an 8-session sports training program. Chi-square and McNemar tests were used and the collected data were analyzed by SPSS 18. Findings: The prevalence of back pain among farmers in both intervention and control groups was 56% and 60%, respectively. There was a significant difference between the percentage of low back pain in the intervention group before and after the training of corrective exercise training (p=0.001). This difference was not significant in the control group (p=0.879). The intervention in the intervention group reduced the back pain by 24%. Conclusion: Intervention of corrective exercise training can reduce the prevalence of low back pain among farmers.

    Aims
    Work-related musculoskeletal disorders are highly prevalent in personnel of hospital service. The aim of the present study was to investigate the effect of ergonomic principles education on temporary musculoskeletal disorders of personnel in hospital service.
    Materials & Methods
    This study is a two-group pre-test, post-test experimental study that was done on 50 people of service staff of educational hospitals of Gonabad, Iran, in 2014. Participants were entered by simple randomized sampling method and then randomly assigned into two intervention and control groups (25 samples in per group). Nordic musculoskeletal questionnaires (NMQ) and Rapid Entire Body Assessment (REBA) questionnaires were completed for both groups. Then ergonomic education was conducted for intervention group and after one month the questionnaires were completed. Mann-Whitney U and Wilcoxon tests were used. The collected data were analyzed by SPSS 16 software.
    Findings: According to REBA, there was a statistically significant difference after intervention (p≤0.001) in two groups. Also, Nordic questionnaire showed a significant difference in upper back (p≤0.003), lower back (p≤0.022), and thigh (p≤0.016) scores after intervention.
    Conclusion
    Ergonomic education can reduce the incidence of musculoskeletal disorders of personnel in hospital service.

    Aims
    Vitamin D is a fat-soluble vitamin and essential nutrient for metabolic and physiological processes in the human body. Vitamin D is a vitally important substance for the body due to its role as vitamin and hormone. The aim of the present study was to assess the effects of different educational programs on vitamin D level of middle-aged women.
    Materials and Methods
    This cross-sectional experimental study was conducted during spring and summer seasons (Six months) in Karaj, Iran, in 2017. Sampling was performed randomly from middle-aged women (30-59 years old with vitamin D deficiency) that refer to comprehensive health centers. 240 middle-aged women were selected and randomly divided into 4 equal groups (n=60 in each group). Preventive behaviors education, supplemental usage education, combination of preventive behaviors and supplemental usage education and control were considered for first to forth groups respectively. After 6 months intervention, the vitamin D serum level in all subjects was measured. The data were analyzed by Independent t test, one way analysis of variance and post hoc test using SPSS 21 software.
    Findings: All of intervention groups had significant difference with control group (p<0.05). The level of vitamin D for group 3 was significantly higher than the other groups (p<0.05). There was no significant difference between groups 1 and 2 (p>0.05).
    Conclusion
    The preventive behaviors and supplementation usage are effective to compensate vitamin D deficiency in middle-aged women, but the combination of preventive behaviors and supplemental usage is more effective.
