Ergonomics Factors Related to Musculoskeletal Disorder of Pineapple Growers in Regional Heath 8

Abstract

            This cross-sectional descriptive study aimed to identify ergonomics factors related to musculoskeletal disorder (MSD) among pineapple growers in Regional Health 8 in 535 samples randomly recruited from population of 2,787 pineapple growers using a systematic sampling method. Data were collected with the questionnaire from January to February 2016. Data analysis included percentage, mean, standard deviation, multiple logistic regress analysis with 95% CI.

            The results showed that the average age of the sample was 47.61±8.92 years old, between the ages of 23 to 67. Most of them were married (registered a marriage certificate) (66.54%), graduated in elementary education (67.10%), the average income was 88,499.07 ±83.955.87 baht, maximum and minimum income was one million and ten thousand baht, respectively. Their health status was found that the samples had underlying disease (14.77%), and having illness while growing pineapple (12.52%). Factors associated with MSD: unchanged working posture more than two hours a day could cause MSD 2.63 times, repeated working posture more than two hours a day could cause MSD 2.67 times, and improper working posture could cause MSD 2.09 times at the significance level less than 0.001. Suggestion: Occupational health and safety service should be provided using job safety analysis for continuous promoting health involving musculoskeletal disorder.
