ABSTRACT
Background and Purpose: Musculoskeletal disorders among the most important occupational health issues nowadays. As the ministry of health is responsible for the community health and providing better services requires healthy workforce, the present study was conducted to determine the prevalence of musculoskeletal disorders in health-treatment employees at Sabzevar University of Medical Sciences, Iran in 2008
Methods and Materials: This cross-sectional descriptive analytical study was conducted on 364 personnel of health treatment employees at Sabzevar University of Medical Sciences, Iran in 2008, who were selected through convenient sampling. The disorders were investigated through Nordik Questionnaire including those in 9 body parts within the past week, past year, and falling behind work due to disorders. The obtained data were analyzed in SPSS 13 using independent test and correlation coefficient.
Results: Mean +/- SD and employment period of the participants were 31.81?6.?? and 9.36?7 respectively. The highest prevalence of the past year in all participants was related to their waist [57.8%], knee [44%] and [42.6%]. However, in participants working for treatment centers, the figures were 61.6%, 46.9% and 48.6% respectively. In the paramedical employees, disorders of was 29.7% and in health center employees, wrist disorders were 28.4%
Conclusion: The prevalence of disorders in university employees is high and the highest rates are related to waist and knee. Disorders of back, waist, knee in the treatment and center employees, and neck disorders in health center employees were higher
ABSTRACT
Refractive errors play important role in the etiology and treatment of strabismus and amblyopia. As screening is one of the common techniques in diagnosing visual disorders, children are, therefore, to be examined for the health of their vision at least once a year. This study is intended to compare the accuracy of Snellen chart and retinoscopy in diagnosis of refractive errors. The target population included guidance-school children in grade one from Sabzevar [2008 female and 2085 male subjects]. Relevant data were collected through interview and clinical examination. Visual acuity of the subjects was examined from a distance of 6m by Snellen chart and those with VA< 10/10 were examined with retinoscopy by an ophthalmologist. The mean visual acuity of both eyes in girls and boys obtained by the Snellen chart turned out to be 0.95 +/- 0.12 and 0.97 +/- 0.09 respectively. Also, 294 subjects appeared to be suffering from refractive errors. In 65% of the cases a significant difference was found between Snellen chart and retinoscopy in diagnosis of refractive errors [p<0.05]. Further research is suggested to reveal the possibility of differences of VA between girls and boys
