Abstract

This survey research aimed at studying prevalence and factors related to muscle pain among an Occupational Class of cloth making womenin Nammong sub-district, Thabo district, Nongkhai province. The sample group consisting of 277 cloth making womenwere interviewed. The results were presented by means of quantity, percentage, mean, standard deviation, medium and range. An influential statistic employed was multiple logistic regression of which the results were depicted via adjusted OR (OR_adj) at the 95% confidence interval.

The results indicated that most of those whose occupations were cloth making womenwere female (95.67%). Their age were or above 51 years old (minimum=20 years old, maximum= 66 years old). Their experience in cloth making womenranged from 6-10 years. 45.49% of the sample group did not do any exercises. Concerning their working postures, 81.59% sat while working but did not lean against the backrest. 95.31% bent and perked. 86.28% work non-stop for a long time. When they had muscle pain, 80.14% looked after themselves by lying on their back; 65.34% got some massage; 35.02% adjusted their working postures. Regarding the period of muscle pain, 69.68% had muscle pain during work; 48.19% had the pain in the morning when awoke; and 22.01 had the symptom after work.

According to the study, it was showed that 85.92% depicted the prevalence of the muscle pain in the past 7-day period. The first three parts of body that depicted the prevalence of muscle pain included 67.10% atboth shoulders (95% CI =61.58–72.71); 65.70% at the right thighs (95 % CI =60.08–71.33); and 64.30% at the right ankles (95 % CI = 58.58–69.94). In addition, 86.64% revealed the prevalence of muscle pain in the past 6-month period. The first three proportions consisted of 65.30% at the right ankles (95 % CI= 59.70–70.98); right wrists and right knees depicted the same prevalence, 64.60% (95% CI= 58.96–70.29); and 57.40% found the prevalence of the pain at the left and right shoulders (95 % CI= 51.54–63.26). Having tested the relationship between the factors related to the muscle pains in the past 7-day period, the results revealed that the factors significantly related to the muscle pain (P<0.05) were the total working hour longer than 11 hours per day(OR_adjj=15.97; 95% CI =1.68-151.82), frequency of brake per day (OR_adj=0.03; 95% CI=0.11-0.60), improper locating of the tools (OR_adj=0.31; 95% CI=0.13-0.74), bending and perking working manner and not leaning against the backrest when working (OR_adj=4.05; 95% CI=1.11-14.76). As for the past 6-month period, it was found that the factor that statistically related (P<0.05) was the continuing sitting and working for a long time (OR_adj=4.32; 95% CI= 1.94-9.63)
