ABSTRACT
Objective@#To study the correlation of occupation musculoskeletal disease (OMD) and safety behavior in assembly line workers.@*Methods@#Selected assembly line workers of 3 manufacturing factory in Pacity as the objects of this study by judgement sampling. Questionnaires were used for messages collection including the general sociodemographic characteristic, OMD condition, occupational safety behaviors.@*Results@#This study shows that, 826 OMD workers were found that the annual prevalence was 38.03%. The scores of work posture, handling habits, health habit in OMD group was lower than non-OMD group (P<0.01) but personal protection behavior was higher than non-OMD group (P<0.01) . Test of binary logistic regression revealed that age, workage, work posture, handling habits were the factors of OMD (P<0.01) .@*Conclusion@#Safety behaviors were the potent factors of OMD that work posture and handling habits should be broadcast.
ABSTRACT
This study involved the assessment of nephrolithiasis risk factors among thirty one (n=31) assembly line workers exposed to heat stress. Assembly line workers working in normal temperature were used as a comparison group. Subjects were matched according to age, body mass index, length of employment and diet. Workplace temperatures were determined using a room thermometer for both groups. Urinary parameters measured include pH, specific gravity, volume, calcium, sodium, phosphorus, uric acid and creatinine. Results showed that the mean levels of urine volume (345.52 +/- 294.88 mL, p0.005483), sodium (121.97 +/- 64.23 mmol/L, p0.006441), calcium (3.39 +/- 2.90 mmol/L, p0.03173), uric acid (3.24 +/- 2.83 mmol/L, p0.046342) and creatinine (11698.93+9091.19 umol/L, p0.035313) were significantly higher in the test group compared to the comparison group. However, there was no significant difference noted in the mean levels of urine pH, specific gravity and phosphorus. The increased risk of nephrolithiasis as assessed in the study was mainly attributed to dehydration during the workshift. Likewise, metabolic acidosis can also provide a possible explanation for the findings
