INTRODUCTION
Business process outsourcing (BPO) workers are a subset of workers that involves the contracting of the operations and responsibilities of a specific business process to a third-party service provider [1]. Business process outsourcing is categorized into back office outsourcing and front office sourcing [2]. It is also known as the “Sunshine sector” in India. As these workers were subjected to prolonged static work and sitting for a prolonged time leads to an increased prevalence of musculoskeletal pain and psychological problems. In India, very few studies have been conducted between the relationship of workplace psychological stress and musculoskeletal disorders and also described about the quality of life. Studies using telecommunication workers evaluated through questionnaire has shown prevalence on musculoskeletal issues and various psychosocial variables.
Work related musculoskeletal disorders includes repetitive strain injuries to bones, tendon and tendon sheath that gradually develop over weeks or months or even years [3]. Biomechanical factors includes prolonged static muscular overload, repeated movements causes risk factors including work related musculoskeletal disorder and psychosocial risk factors of work [3]. Among business process outsourcing workers there is often complaints of musculoskeletal disorders such as pain over cervical region, fatigue and psychological distress. Risks of neck shoulder symptoms were associated with high job strain. Improper posture causes musculoskeletal disorders mainly includes use of arms, wrists and fingers and viewing more time in computer screen and lack of forearm support and not sufficient working space [4].
Due to the nature of job of the workers they have to face the stressful consequences called the “burn out syndrome” which is characterized by chronic fatigue, insomnia, and alternative of the 24 hours biological rhythm. Sleep deprivation is found in major group of night duty workers and this may lead to depression and poor cognitive functioning and burnout is usually caused due to psychological fatigue [5]. Sedentary unhealthy lifestyle lead to volley of problems that affect one’s psychosocial, physical and mental health [6]. Improper BMI (body mass index) may tend to produce musculoskeletal discomfort and occupational psychological stress. Improper sitting and using wrong chairs for a prolonged time in front to the computer may tend to produce stiffness, headache and backache and may cause inflamed muscles and tendons and overuse injuries to hands and wrists [7].
There were 2 questionnaires used in this study: Stress and burnout questionnaire, Cornell musculoskeletal discomfort questionnaire. Stress and burnout questionnaire has been used for assessing burnout stress syndrome and Cornell musculoskeletal discomfort questionnaire was used for assessing musculoskeletal disorders. The aim of the study is find out the prevalence of work related psychological and musculoskeletal problems among business process outsourcing workers.
Even though several studies has been mentioned about business process outsourcing workers and their lifestyle pattern and less number of studies has been mentioned about the psychological and musculoskeletal problems among business process outsourcing workers. And very few study has been mentioned about the body mass index of the workers and the relationship between the musculoskeletal problems and body mass index. It is important to know the occurrence of the problems, for further more studies and which would provide precaution for the workers and this could definitely improve their quality of life in a better way. So this study is been done to work related psychological and musculoskeletal problems among business process workers.
MATERIALS AND METHODS
A Non experimental, Observational type of study was done in Erfolg techno solutions, T Nagar, Chennai on 100 subjects for a duration of 4 weeks. The samples were selected by method of Convenient sampling who met the inclusion and exclusion criteria.
The participants who were between the age group of 20-35 years of age, both male and female and those who had been working for more than a year in business process outsourcing for more than 9 hours/day were included in the study. While individuals with a History of any injury to the upper and lower extremities, History of any injury to spine and Pregnant women were excluded from selection. Two questionnaire and BMI calculator application were used as an outcome measure for obtaining values.
The subjects were selected based upon the inclusion and exclusion criteria and the consent form is obtained from the subjects and the procedure was explained. The subjects were randomly selected among the business process outsourcing workers in Chennai. The evaluation was taken through stress and burnout questionnaire that has been used to assess the burn out syndrome. The Cornell musculoskeletal discomfort questionnaire has been used to assess the region wise musculoskeletal problem. Since Cornell musculoskeletal discomfort questionnaire had no scoring it was assumed to be scored as respective numbers and it was evaluated and body mass index was evaluated through the height, weight and age of each subject and evaluated through body mass index calculator application. The ranges of body mass index were evaluated as 1 - Underweight (17.0-18.4), 2- Normal (18.5-24.9), 3 - Overweight (25.0-29.9). And correlation between body mass index and musculoskeletal problem was been done.
The data was analyzed using IBM SPSS statistics version 22. The descriptive and chi-square test has been used to analyze the data.

DISCUSSION
The objective of the study was to find out the work related psychological and musculoskeletal problems among business process outsourcing workers. According to several studies, business process outsourcing workers are more prone to musculoskeletal problem [8]. They tend to get psychological problems also. This study is done to show that the prevalence of musculoskeletal problems and psychological problems among business process outsourcing workers.
This study mentions that musculoskeletal pain accounts for about neck 51%, shoulder 37%, upper back 4%, upper arm 5%, lower back 46%, forearm 9%, wrist 44%, hip/buttocks 51%, thigh 1%, knee 1%, lower leg 1%. And neck, hip/buttocks accounts for about 51% and is the maximum of the musculoskeletal pain. Upper limb has high prevalence of musculoskeletal symptoms especially in neck- shoulder region [9]. The symptoms of neck 39%, shoulder 22%, hand and wrist 10%. Stress and burnout questionnaire has been used to assess the psychological status of the subjects and in this study only 2% of the population has been affected with the psychological issues. This study mentions that Burnout stress syndrome accounts for about 54% and that too it is found in 2% of the population [10-12]. The results were in controversy with high frequency of psychological distress and the health impact of working conditions were found in the survey of over 2000 call Centre workers.
The study shows that the subjects with the psychological issues or the workers suffering from stress exhibit absenteeism, decreased productivity have a higher number of accidents, have lower morale and greater interpersonal conflict with colleagues and superiors [13]. Long hours of work, night shifts, high work targets and loss of identity are some of the concerns of the call Centre industry in India [14]. The study concluded that improved workstation design, thermal comfort environment, well-scheduled work rest regime and realistic production goals are the preventive measures for musculoskeletal disorders (MSD) among call center. When correlating body mass index and musculoskeletal problems, there is not much significance [15]. The results were in controversy with major effect of body mass index in increasing work related musculoskeletal disorders and occupational psychosocial stress and sedentary office workers in a stressful job with high body mass index will have more eating behavior, thereby they are more prone to have a weight gain which leads to obesity adding further occupational stress. In contrast, the weak association also has been seen between body mass index and Occupational stress of aggravated scores [16-18]. Since this study correlates the influence of body mass index with the musculoskeletal pain and hence the study shows there is no influence of body mass index with the musculoskeletal pain. The sleep deficit in night shift workers can lead to serious disruption in their daily life routine, including excessive sleepiness during the day, poor quality of sleep and chronic fatigue [19].
CONCLUSION
The study concluded that there is a higher prevalence of work related musculoskeletal disorders including neck region, hip/buttock, wrist and low back region with the highest rates and less prevalence of burnout stress syndrome among business process outsourcing workers . There is no significance while correlating body mass index with the musculoskeletal problems. Burnout stress syndrome accounts for about 54% and that to it is found in 2% of the population and musculoskeletal problems mainly neck accounts for about 51%. Some of the limitations of the study were small sample size and different working environment. For future studies recommendation such as Specification of women business process outsourcing workers can be included for the future study and Future study can be included as such as work site modification which can reduce musculoskeletal discomfort risk factors, psychological counseling, ergonomic setup among the workers for better results and prevention.
