“…This finding proved that if workers are exposed to A (8) of HAV above the European Directive limit of 5 ms ‐2 , as much as 33.23% and 38.80% more of the workers reported symptoms of finger tingling and numbness compared to workers exposed below the European Directive limit of 5 ms ‐2 . A study done among grasscutters in Southern Region of Malaysia further supported this finding, where about 20% and 30% more of the high exposure group reported finger tingling and numbness compared to the low‐moderate group …”

“…HAV are known to lead to muscle damage that can cause weakness of the hand grip. A study among grasscutters found that the prevalence ratio of the grasscutters in the high exposure group was about 1.5 times more likely to report hand grip weakness than the low‐moderate group . A study among workers using rock‐crushing equipment in Sweden further strengthened this finding, where it was reported that the rock‐crushing workers had significantly lower hand grip by 7% ( P = .009) than a group control of male policeman not exposed to HAV …”

“…Workers mainly in the manufacturing, mining, forestry, and construction industries are at risk of developing HAVS as their work involves the handling of pneumatic and electric vibrating tools . Available local evidence for construction workers, grass cutters, foresters, and traffic police riders states that HAVS is a major occupational health problem for Malaysian workers, with a prevalence ranging between 15% and 30% . Due to rapid industrialization, urbanization, and lack of good quality public transportation in most major cities, the number of cars in Malaysia is increasing rapidly .…”

Background Prolonged exposure to hand‐arm vibration is associated with a disorder of the vascular, neurological, and musculoskeletal systems of the upper limb known as hand‐arm vibration syndrome (HAVS). Currently, the evidence of HAVS in tropical environments is limited. Objectives To determine the prevalence and severity of HAVS among tyre shop workers in Kelantan, Malaysia. Methods A cross‐sectional study involving 200 tyre shop workers from two districts in Kelantan was performed. Part one data were collected at the field using questionnaire, and hand‐arm vibration was measured. Part two involved a set of hand clinical examinations. The workers were divided into high (≥5 m s‐2) and low/moderate (<5 m s‐2) exposure group according to their 8‐hr time weighted average [A(8)] of vibration exposure. The differences between the two exposure group were then compared. Results The prevalence of the vascular, neurological, and musculoskeletal symptoms was 12.5% (95% CI 10.16 to 14.84), 37.0% (95% CI 30.31 to 43.69), and 44.5% (95% CI 37.61 to 51.38) respectively. When divided according to their exposure statuses, there was a significant difference in the prevalence of HAVS for all three components of vascular, neurological, and musculoskeletal (22.68% vs 2.91%, 62.89% vs 12.62% and 50.52% and 38.83%) respectively. All the clinical examinations findings also significantly differed between the two groups with the high exposure group having a higher abnormal result. Conclusion Exposure to high A(8) of vibration exposure was associated with a higher prevalence of all three component of HAVS. There is a need for better control of vibration exposure in Malaysia.

“…Studies among grasscutter workers in Malaysia reported that increasing BMI does not influence the development of neurological complications of HAVS. 5 However, another study among motorcycle rider in India reported being obese as a risk factor for HAVS. 27 A study among Finnish dentists also supported our findings.…”

“…4 Available limited local evidence in Malaysia among construction workers, grass cutters, foresters, and traffic police riders, found that HAVS is a major occupational health problem for workers exposed to hand transmitted vibration with prevalence ranging between 15% and 30%. [5][6][7][8] Based on the 2010 Malaysia national labor force statistics reports, it is estimated that more than four million workers in Malaysia are in occupation at risk of developing HAVS. 8 There is currently no national legislation in Malaysia to protect workers against occupational HAV exposure, unlike for occupational noise exposure, which is regulated.…”

Objective Prolonged exposure to hand‐arm vibration (HAV) at the workplace is associated with hand‐arm vascular syndrome (HAVS). This study aimed to determine the prevalence and the factors associated with the vascular and neurological complications of HAVS among tire shop workers in Kelantan, Malaysia. Methods A cross‐sectional study involving 200 tire shop workers from two districts in Kelantan was conducted. Data were collected at the field using Malay Translated HAVS questionnaire, and hand‐arm vibration was measured. Multiple logistic regression analysis was used to determine the associated factors. Results The prevalence of vascular and neurological complications of HAVS among the tire shop workers was 12.5% (95% CI: 10.16, 14.84) and 37.0% (95% CI: 30.31, 43.69), respectively. From multiple logistic regression analysis, only A(8) of HAV exposure was significantly associated with the development of vascular complications and A(8) of HAV exposure, age. and body mass index were significantly associated with the development of neurological complications of HAVS. Conclusion This study has identified that HAVS is a significant problem among workers exposed to HAV in a warm environment. A(8) of HAV exposure is significantly associated with the development of both vascular and neurological complications. Therefore, there is a need for better control of vibration exposure in Malaysia.

Hand-arm vibration disorder among grass-cutter workers in Malaysia

Abstract: The results suggest that HAVS is under-diagnosed in Malaysia, especially in the agricultural sectors. More information related to safety and health awareness programmes for HAVS exposure is required among hand-held grass-cutting workers.
