Abstract

Musculoskeletal disorders (MSDs) are the major causes of illness among working age group. This cross-sectional study aimed to identify prevalence of MSDs, the influences of between ergonomic riskson (MSDs) among beverage factory workers, Indonesia. This cross sectional study systematic randomly selected 309 samples from all 3 sectors of a beverage factory proportional to size of the population to response to a structured questionnaire, standardized Nordic questionnaire and physical assessment by physiotherapists. The relationships between ergonomic risk factors and MSDs when controlled covariates were assessed using multiple logistic regression. The prevalence of MSDsusing standardized Nordic questionnaire was 71.84% during the last 7 daysand58.90% for the past 12months.The prevalence of MSDs diagnosed by physiotherapist was 56.31%. The multivariate analysis identified that when control other covariatesHigh ergonomic risks on the left of shoulders were significantly increased MSDs during past 12 months (AdjOR:3.54-95%CI:1.49 to 8.37) and MSDs diagnosed by physical assessment (AdjOR:2.91-95%CI:1.30 to 6.52). High ergonomic risks on the neck lead to the increasing of MSDs during the last 7 days (AdjOR:2.15-95%CI:1.27 to 3.65), past 12 months (AdjOR:5.31-95%CI:2.53 to 11.11) and also MSDs diagnosed by physical assessment (AdjOR:4.35-95%CI:2.11 to 8.96) with all of them. Smoking and education also had influences on MSDs. Ergonomic risks had impacts on MSDs both in long and short terms with the super imposed of smoking and socioeconomic status.
