FACTORS ASSOCIATED WITH MUSCULOSKELETAL DISORDERS AMONG RICE FARMERS IN TARNLALORD SUB-DISTRICT PHIMAI DISTRICT NAKHON RATCHASIMA PROVINCE THAILAND

Abstract

The aims of this study were to investigate factors association with musculoskeletal disorders among rice farmers to presence the prevalence and explore the association. The participants were rice farmers who are growing rice at least one year experience in Tarnlalord sub-district, Phimai district, Nakhon Ratchasima province. This study was conducted as a cross-sectional design on 290 subjects aged between 20 to 59 years old. Descriptive analysis of data identified most common process that affecting the rice farmer of Tarnlalord sub-district were planting & transplanting process. Paddy preparation process, the highest prevalence was shoulder (71.7%). For harvesting, the highest prevalence was in shoulder pain (64.8%). The analysis used Chi-Square test to find association between 2 groups of factors (individual factors, work-related factors) and total body pain score of MSDs. The results were identified six factors significantly associated with musculoskeletal disorders: female (OR=3.180, 95% CI=1.966-5.143), abnormal BMI group (OR=0.607, 95% CI=0.377-0.977), education below high school (OR=0.535, 95% CI=0.313-0.915), non-smoker group (OR=2.169, 95% CI=1.137-4.141), farming experience 26 to 50 year (OR=2.169, 95% CI=1.350-3.483), have underlying disease (OR=2.013, 95% CI=1.202-3.372). From presented study, all process of rice growing were affected to musculoskeletal system by several related factors. This requires improved farming management systems in process of rice growing and including education or recommendation to reduce the pain of the musculoskeletal system.
