The purpose of the study was to determine the thermal and cardiac stress among female brick field workers. Thermal and cardiac stress plays an important role in the ability to perform the work. A cross-sectional study was conducted on 112 female brick field workers from 12 brick fields of West Bengal, India. Thermal stress was also assessed by measuring the WBGT index. Cardiac strain in different seasons were measured in terms of work heart rate (WHR), relative cardiac cost (RCC), net cardiac cost (NCC), cardiovascular stress index (CSI) and other recovery indices among the female brick field workers. The net cardiac costs of the brick stackers were higher in comparison to brick moulders and carriers. NCC and the RCC levels were higher among the brick stackers than in other groups of brick field workers. The CSI levels were the maximum in the case of carrying raw mud activities. In these activities, the brick field workers changed their posture frequently during loading and unloading and walking with mud. The frequent change of postures imposed extra load on the cardiovascular system. This study concluded that due to heat stress, the productivity of the three groups of workers were affected.
The purpose of this study was to develop a job competency model of workplace health education in order to provide standardized and unified tools for occupational health professionals. The study was conducted by using methodological study design. Literature review, job analysis, and job validity verification were conducted. A convenience sample of 485 occupational health professionals participated in the study. Through a literature review and job analysis, job competency of workplace health education was structured. Verification of validity was achieved among university-research industries with various professionals affiliated with occupational health professionals. Verified job competency model of workplace health education for occupational health professionals consisted of eight duties and 40 tasks. The tasks given high performance and importance by occupational health professionals were included in the ‘planning’ and ‘implementation’ factors. The tasks which were considered important but were not performed relatively well were included in the ‘evaluation and improvement’ factor. The results indicated that the job competency model of workplace health education for occupational health professionals is a validated tool. Further studies are needed to explore the performance levels based on the job competency model of this study.
In rice cultivation, post-harvesting tasks are essential for the preparation of rice from paddy where mainly female workers perform a sequential work through manual efforts. The present study was aimed to evaluate musculoskeletal disorders (MSDs) and postural stress of female workers engaged in different post-harvesting jobs. This cross-sectional study was conducted on 120 female cultivators in different districts of West Bengal State, India. The modified Nordic questionnaire was applied to identify the MSDs in different body parts. The postural stress was analyzed by four methods, viz, OWAS, RULA, REBA and QEC. The results show that the prevalence of MSDs was very high among the workers and the most affected areas were the lower and upper back, shoulder, wrist, knee and calf. Postural analysis indicated that the participants had to adopt different stressful postures during performing different post-harvesting jobs. Postural stress might be the reason of the occurrence of MSDs. From this study it has been recommended that workers should avoid inadequate work postures as far as possible during their work for reducing job-related health hazards.
The purpose of this study is to examine the effectiveness of environmental adjustments and activity programs implemented by occupational therapists with regard to dementia-related fall prevention. In this quasi-experimental study, the intervention group for the corrective measures was comprised of 38 patients; the intervention continued for a 12-week period. A controlled study was then conducted by comparing that group to a control group consisting of 29 patients over the same period. Members of the intervention group were examined individually by occupational therapists then underwent customized intervention of the fall prevention. The results of this analysis showed that a comparison of the control group between pre-intervention and during intervention revealed no change. The intervention group exhibited a significant communication reduction in the number of falls (P=0.004). These findings suggest that the programs implemented by dementia-related occupational therapists are effective ways to prevent falls.
