Abstract

Introduction: Musculoskeletal disorders (MSDs) are common consequences of poor working conditions associated with computer use. Regarding the lack of information about MSDs and the extensive use of computer among the university students in our country, this study aimed to explore the awareness level of ergonomic considerations in computer use and the prevalence of MSDs among university students.

Materials and Methods: This cross-sectional study was conducted on 450 students of three faculties of medicine, dentistry and paramedical of Babol University of Medical Sciences in 2012. The subjects were selected by simple sampling method. The data were gathered by the researcher-made questionnaire consisting of 6 open and 10 closed questions. Data processing was performed by using descriptive statistics and chi-square test.  

 Results: The mean (SD) age of students was 21.7 (2.5) years, 64% were females and 67% were undergraduate students. Ninety percent of the students had personal computer and 48% had spent 1 hour or more on their computer daily. It has been reported that approximately 55% of students had suffered from MSDs and less than 10% of them had been familiar with ergonomic considerations in computer use. Chi-square test indicated a significant difference in the incidence of MSDs in terms of the duration of working with computer (p<0.05).

 Conclusion: The complaints of MSDs in about half of the students and the lack of awareness of ergonomic considerations in most of them suggest the possibility of increasing future problems. Therefore, regarding the inclination of most students in receiving information and their influential role in the dissemination of knowledge, performing interventional programs including education in computer ergonomic principles is recommended.   Normal 0 false false false EN-US X-NONE AR-SA

Abstract

Background: Undesirable sit-up and deviation from desirable status is one of the factors affecting the health of students in the classroom. The purpose of this study was to evaluate the relationship between posture and musculoskeletal pain in boys 9 to 13 years old.
Methods: In this correlation study, the population consisted of all boy students in the primary city of Birjand. 60 students were selected as a sample group based on random-cluster method. Two video cameras were recorded 30 minutes of sitting position for every student. The anthropometric characteristics of subjects including height, weight, etc., were measured with a standard tool. The back and neck pain were collected using a modified Nordic questionnaire. Moreover, the kinovea software was used to analyze the flexion and rotation angle during sitting. The statistical calculations were applied by Kolmogorov-Smirnov normality test. The ETA correlation coefficient also was used to identify the relationship between variables. All statistical calculations performed using SPSS version 21.
Results: The result indicated significant relationship between bending and rotation angles with both neck and back pain (P≤0.05). Therefore it would be noticed that improper sitting can be accounted as a cause of muscle-skeletal pain in boy students based on bad postures during sitting.
Conclusion: According to the results, the posture of students while sitting in class is inadequate and harmful. Thus performing some intervention and education for students is recommended.

Abstract

Background and Aim: A well-designed desk and chair, in addition to proper learning, can prevent changes in the user's physical form. Therefore, this study aimed to determine the anthropometric characteristics of students in the College of Agriculture and Natural Resources located at the University of Tehran to design an ergonomic table and chair.
Methods: In this research, 18 anthropometric characteristics including the popliteal height, knee height, shoulder height, eye height, sitting height, elbow support height, elbow height, knotted elbow length, hip-popliteal length, hip-knee length, thigh thickness, abdominal depth, chest depth, hip width, shoulder width, the transverse width of the elbows, height, and as well as weight for 260 students (130 girls and 130 boys) aged 18 to 35 years were investigated. To collect data, an anthropometric chamber and chair were used. Finally, according to the measured physical dimensions of the students, the Dimensions of ergonomic table and chair were calculated and designed according to the INSO 9697-1 standard.
Results: Anthropometric dimensions of students were obtained through mean, minimum, maximum, standard deviation, mean, and the percentile value of 2.5 to 97.5 using SPSS version 20 software. The results showed that the age of the user does not have a significant effect on the size of the table and the chair. Also, the results showed that there was a significant difference in popliteal height between girls and boys.
Conclusions: Considering the difference in dimensions between female and male students, it was found that the popliteal height in the percentile of 5 for boys is 4 cm more than girls. Therefore, using measured anthropometric characteristics, the dimensions of the chair and table ergonomics were designed in two sizes.
