Work urgency, accuracy and demands compel the computer professionals to spend longer hours before computers without giving importance to their health, especially body weight. Increase of body weight leads to improper Body Mass Index (BMI) may aggravate work related musculoskeletal discomfort and occupational-psychosocial stress. The objective of the study was to find out the effect of BMI on work related musculoskeletal discomforts and occupational stress of computer workers in a developed ergonomic setup.
A descriptive inferential study has been taken to analyze the effect of BMI on work related musculoskeletal discomfort and occupational-psychosocial stress. A total of 100 computer workers, aged 25-35 years randomly selected on convenience from software and BPO companies in Bangalore city, India for the participation in this study. BMI was calculated by taking the ratio of the subject's height (in meter) and weight (in kilogram). Work related musculoskeletal discomfort and occupational stress of the subjects was assessed by Cornell University's musculoskeletal discomfort questionnaire (CMDQ) and occupational stress index (OSI) respectively as well as a relationship was checked with their BMI.
A significant association (p < 0.001) was seen among high BMI subjects with their increase scores of musculoskeletal discomfort and occupational stress.
From this study, it has been concluded that, there is a significant effect of BMI in increasing of work related musculoskeletal discomfort and occupational-psychosocial stress among computer workers in a developed ergonomic setup.
工作的紧迫性、准确性和要求迫使计算机专业人员长时间坐在电脑前，而不重视自身健康，尤其是体重。体重增加会导致身体质量指数（BMI）不当，这可能会加重与工作相关的肌肉骨骼不适和职业心理社会压力。本研究的目的是在发达的人体工程学环境中，找出BMI对计算机工作者与工作相关的肌肉骨骼不适和职业压力的影响。
采用描述性推断研究来分析BMI对与工作相关的肌肉骨骼不适和职业心理社会压力的影响。从印度班加罗尔市的软件和业务流程外包公司中，随机选取了100名年龄在25至35岁之间的计算机工作者参与本研究。BMI通过受试者的身高（米）与体重（千克）之比来计算。分别通过康奈尔大学的肌肉骨骼不适问卷（CMDQ）和职业压力指数（OSI）评估受试者与工作相关的肌肉骨骼不适和职业压力，并检查其与BMI的关系。
高BMI受试者的肌肉骨骼不适和职业压力得分增加之间存在显著关联（p < 0.001）。
从这项研究可以得出结论，在发达的人体工程学环境中，BMI对增加计算机工作者与工作相关的肌肉骨骼不适和职业心理社会压力有显著影响。
