Association between work stress and necks pain among electronics assembly industrial workers in Northeast Thailand

Abstract

This cross-sectional analytic study aimed to investigate work stress of northeastern electronics manufacturing and assembly industry workers. Data collection was conducted in April 2022, the subjects used from cluster randomization as an electronics industrial workers located in the Northeast Thailand.

The results showed that that the majority of employees were female, with the highest proportion of age was between 30-39 years old range being 38.91%, positions were mostly operator (77.04%), work experience was less than 5 years (89.88%). The main task of workers was inspection of pieces of electronic (40.47%), Work in an average of 6 days (85.21%), worked overtime (68.48%), repetitive work in the same position (87.55%), worker used their eyes focused on performing (62.26%). They had relatively low workload (54.86%), ability to control work was at a low level (78.21%), fatigue was likely high for 62.65%, had hazard or accident risk for 56.81%, work fatigue for 59.92%, difficulty and complexity of work was 65.76%, work time was 62.65%, work responsibility was 80.16%. The high work stress of worker was 56.42%.

Ergonomics risk measured neck position by BRIEF survey was that 33.46 % were at risk level 3 and 4 (high to very high risk level, needed improvement), shoulder position ergonomics risk level 3 and 4 for 29.57%. Pain perception severity was observed at a very high level on neck (26.46%), shoulder (15.18%). Frequency of pain was based on pain perception at very high level, on neck (26.46%) and shoulder (15.18%). Work stress level was correlated with perception of shoulder pain perception severity at correlation coefficient (r) (r=0.126, p-vlaue =0.042).

This study showed the significant work stress of working process indicated work stress. The significant risk factors of work stress finding could be useful for the next stage of แcomplementation.
