Rubber tapping processes posed potential risk of various health problems among rubber workers. It ranges from simple musculoskeletal aches to more serious and complicated structural damage to bone, muscles, tendons and nerves of musculoskeletal system. These health problems might be linked directly to the arduous demands of farm labor. OBJECTIVES: A cross-sectional study was conducted to determine the prevalence of neck pain (NP) and musculoskeletal symptoms (MSS) and its association with personal characteristics, physical workloads and psychosocial factors among rubber workers. METHODS: Stratified random sampling method was adopted and a total of 419 rubber workers in FELDA's scheme Malaysia participated in this study. Data was collected through face to face interview using modified Standardized Nordic Questionnaire (SNQ) and Job Content Questionnaire (JCQ). RESULTS: The results revealed the prevalence of NP was 59.9% and weak correlation with age (?= -0.184, p= 0.001) and a positive weak correlation with working hours per day (?= 0.099, p= 0.043) significantly. All physical workloads (neck flexion or rotation, awkward postures, repetitive motion and static postures) had significant weak to moderate positive correlation with NP (p<0.05). Job insecurity was found to have weak and positive correlation with NP (p<0.05). Binary logistic regression analysis showed risk factors for NP were decreased with age (OR= 3.92, 95% CI 1.61 - 9.58, p=0.003), increase in neck flexion or rotation (OR= 9.52, 95% CI 5.55 - 16.32, p= 0.001), awkward postures (OR=2.23, 95% CI 1.29 - 3.86, p= 0.004) and static postures (OR= 1.86, 95% CI 1.10 - 3.14, p= 0.021). CONCLUSION: This study showed that high prevalence of NP was associated with neck flexion or rotation, awkward and static postures.

The present study investigates the relationship between psychosocial work factors and health-related quality of life (HRQOL) in male automotive assembly plant workers in Malaysia. MATERIALS AND METHODS: A total of 728 male workers were recruited in March-July 2005 from 2 major automotive assembly plants in Selangor and Pahang. In this cross-sectional study, information on socio-demography, psychosocial work factors using the 97-item Job Content Questionnaire (JCQ) and an abbreviated 26-item version of the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF) questionnaire containing 4 domains (physical health, psychological, social relationship, and environment) was self-administered to all workers involved. RESULTS AND CONCLUSION: The prevalence of reported good or very good overall HRQOL and general health was 64.9% and 53.7%, respectively. Multiple linear regression analysis indicated that created skill was positively associated with physical health and psychological domains; whilst, skill discretion was positively associated with social relationship and environment domains. Social support was positively associated with physical health and environment domains; whilst, co-worker support was positively associated with psychological and social relationship domains. Job insecurity and hazardous condition were negatively associated with all domains, whilst psychological job demands was negatively associated with the environment domain of HRQOL.


A Clinical Survey of Paraquat Formulation Workers.

Howard J. K.
Br J Ind Med. 1979; 36(3): 220-3

A group of 18 male Caucasian workers from the United Kingdom and a further group of 18 male mixed race (mainly Malay) workers from Malaysia employed in the formulation of paraquat-based herbicides were examined for evidence of chronic ill health after long-term exposure to paraquat. Clinical records were examined, medical and occupational histories were obtained and a clinical examination, particularly of the skin, was undertaken. Skin rashes, nail damage and epistaxes were encountered by most workers as a result of direct contact of skin and mucous membranes with paraquat. These conditions subsided rapidly and no worker reported any sequelae. There was no clinical evidence of long-term effects on skin, mucous membranes or general health following exposure to paraquat over several years in these workers.

OBJECTIVES: The objectives of this study were to determine the psychological fatigue and analyze muscle activity of production workers who are performing processes jobs while standing for prolonged time periods. METHODS: The psychological fatigue experienced by the workers was obtained through questionnaire surveys. Meanwhile, muscle activity has been analyzed using surface electromyography (sEMG) measurement. Lower extremities muscles include: erector spinae, tibialis anterior, and gastrocnemius were concurrently measured for more than five hours of standing. Twenty male production workers in a metal stamping company participated as subjects in this study. The subjects were required to undergo questionnaire surveys and sEMG measurement. RESULTS: Results of the questionnaire surveys found that all subjects experienced psychological fatigue due to prolonged standing jobs. Similarly, muscle fatigue has been identified through sEMG measurement. Based on the non-parametric statistical test using the Spearman's rank order correlation, the left erector spinae obtained a moderate positive correlation and statistically significant (r(s) = 0.552, p < 0.05) between the results of questionnaire surveys and sEMG measurement. CONCLUSION: Based on this study, the authors concluded that prolonged standing was contributed to psychological fatigue and to muscle fatigue among the production workers.
