Work-Related Musculoskeletal Disorder an Increasing Concern in Garment Industry

  Background:  Musculoskeletal Disorders (MSDs)-related occupational health concerns are becoming a growing problem for the clothing industry, which is influenced by the repetitive tasks, prolonged static postures and poor ergonomic conditions that characterise the nature of work in this industry. This study aims to provide a thorough assessment of the numerous musculoskeletal problems that are prevalent in the garment industry and to recommend useful intervention strategies to mitigate their consequences. Methods:  One hundred thirty textile workers aged between 25 to 45 years were taken randomly from five different textile manufacturing sites of Baranagar, West Bengal. A modified Nordic musculoskeletal questionnaire was applied to evaluate the postural stress of the garment’s workers. The discomfort/pain intensity in different body parts were evaluated by Body Part Discomfort (BPD) scale . Appropriate statistical tests were applied. Results: Discomfort or pain in hip and lower back were found to be maximum among workers. Conclusion: Pain, discomfort and postural stress among various body parts like upper back, lower back and hip are verry much common for the workers. Despite efforts to deal with these problems, more thorough research and efficient intervention strategies are required to reduce musculoskeletal ailments in the garment industry.

Prevalence Of Work-Related Musculoskeletal Disorders Among Construction Workers

Construction workers frequently have work-related musculoskeletal disorders (WRMSDs) with significant adverse health and financial effects. The aim of this study is to look at the reasons, effects, and prevention measures for WRMSDs among construction workers.Methods: In the study, one hundred thirty-six male construction workers between the ages of 30 and 56 participated. The postural stress experienced by the construction workers was assessed using a modified Nordic musculoskeletal questionnaire. The Body Part Discomfort (BPD) scale was used to assess the severity of the discomfort/pain in various body areas.Results: Discomfort or pain in neck portion was found to be maximum percentage of workers. BPD scaling revealed that neck, lower back and shoulder are among three most susceptible body parts in relation to pain sensation.Conclusion: Manual construction workers in the construction industry are particularly vulnerable to developing work-related musculoskeletal disorders (WRMSDs), working hours and MSD symptoms, particularly in the lower limb, are significantly correlated

Role of living conditions and socioenvironmental factors on chronotype in adolescents

An individual's chronotype, defined as the preference for rest and activity at different times of the day, is linked to several physiological and psychological outcomes. Research on environmental determinants of chronotype has focussed mostly on geographic location, whereas other socioenvironmental determinants have been neglected. We aimed to investigate the association between other previously unrecognized socioenvironmental factors and chronotypes in adolescents. We analysed data of 1916 Bengali adolescents (aged between 13-14 years, 47% girls). Chronotype was determined by the reduced morningness-eveningness questionnaire (rMEQ), and socioenvironmental factors were identified through a structured questionnaire. Associations were analysed using multinomial logistic regression models. Our findings demonstrated that living in urban areas, the presence of a smoker at home, and higher parental education were associated with a higher evening activity (eveningness), while the use of biomass cooking media (compared to liquefied petroleum gas) and assisting parents in farming were associated with higher morningness in adolescents. This is the first study to identify the association between previously unrecognized socioenvironmental factors and chronotypes delineating the interaction between environment and sleep in adolescents and might help the parents to understand the importance of a proper sleep-activity rhythm of their kids through a comprehensive understanding of their surrounding environment and other factors

Animal Welfare Attitudes: Effects of Gender and Diet in University Samples from 22 Countries

Animal Welfare Attitudes (AWA) are defined as human attitudes towards the welfare of animals in different dimensions and settings. Demographic factors, such as age and gender are associated with AWA. The aim of this study was to assess gender differences among university students in a large convenience sample from twenty-two nations in AWA. A total of 7914 people participated in the study (5155 women, 2711 men, 48 diverse). Participants completed a questionnaire that collected demographic data, typical diet and responses to the Composite Respect for Animals Scale Short version (CRAS-S). In addition, we used a measure of gender empowerment from the Human Development Report. The largest variance in AWA was explained by diet, followed by country and gender. In terms of diet, 6385 participants reported to be omnivores, 296 as pescatarian, 637 ate a vegetarian diet and 434 were vegans (n = 162 without answer). Diet was related with CRAS-S scores; people with a vegan diet scored higher in AWA than omnivores. Women scored significantly higher on AWA than men. Furthermore, gender differences in AWA increased as gender inequality decreased

An ergonomic study of postural stress of nurses working in orthopedic wards

It was reported high prevalence of musculoskeletal disorders among nurses. Among the wards, personnel working in Orthopedic wards routinely perform activities that require lifting heavy loads in awkward posture. Challenges faced by them assess patients skillfully and uniquely because orthopedic patients typically present with multiple, complex health problems. During orthopedic patient handling work-related postural strain are most common in health care unit personnel. This study aims at evaluating the different work-related musculoskeletal strain due to awkward postures, body parts discomforts, and find out some ergonomic solutions to these problems. Forty nurses working in orthopedic settings of two hospitals were interviewed by modified Nordic Questionnaire to reveal the prevalence of musculoskeletal problems and pain in various regions of the body. BPD Scale was used to identify the intensity of different body parts discomforts. Video recordings and still photographs were taken to evaluate postural stress during different activities were analyzed by OWAS (Ovako working posture analysis) method. Activity analysis chart was also used to represent the duration of different activities of nurses in their respective duty hours. It was observed that the most physically demanding and postural strenuous task is transferring patient alone. In orthopedics wards different activities like assist patient to walk, changing, other care works are strenuous because as about 90% of adult patient are over 50 kg of body weight and due to facture or other problem are unstable. Some ergonomic interventions like assisted lifting, lifting aids, training, etc. are recommended to improve the working conditions and reduce postural strain.

An ergonomic evaluation of tasks of healthcare unit personnel in different shifts in General Hospitals in West Bengal

Background: The job challenges faced by healthcare unit personnel are psychological, temporal and physically demanding.  Studies on psychological stress on nurses are available but unfortunately studies on physiological load or temporal analysis of tasks of nurses or attendants in general hospitals in India have not been reported so far. Objective: The study aims at evaluating the perception of workload in different shifts among healthcare unit personnel and to develop better ergonomic management protocols. Participants: The study population comprised 150 staff nurses and 175 attendants working in three government hospitals in West Bengal, India. Method: The amount of time spent by nurses and attendants performing different tasks were recorded throughout the shifts using an activity analysis chart along with perceived exertion rating and heart rate throughout the shifts. Results: About 26.8% of the total working time throughout the day was spent in “direct care”. In case of general duty attendants 24.4% of the duty time was spent in indirect care. Time spent in different tasks differed by shifts. More leisure time occurs in the night shift compared to the morning and afternoon shifts but duration of shift was longer (11 to 12 hours). Perceived exertion rating of healthcare unit personnel in night shift was more compared to other shifts but physiological response did not reflect that. Conclusion: There were temporal variations of job demand in healthcare units. So, ergonomic orientation of layouts of departments, arrangement of activities, ergonomic way of keeping the records and use of proper communication system, recommended reducing the stress of healthcare unit personnel.DOI: http://dx.doi.org/10.3126/ijosh.v2i2.6566 International Journal of Occupational Safety and Health, Vol 2.

Chronotype assessment of the Bengalese adolescents: an observational study using a Bengali version of the reduced Morningness-Eveningness Questionnaire (rMEQ)

Chronotype or morningness orientation is an interpersonal characteristic that influence human physiology and psychology and less is known about the chronotype of the Bengalese adolescents in India. We aimed to study the chronotype of this population by using a translated version of a previously established questionnaire. 471 Bengali-speaking adolescents (13–14 years) (boys = 268, girls = 203) of West Bengal, India were included in this study and their chronotype was assessed using an interviewer-administered Bengali version of the reduced Morningness–eveningness Questionnaire (rMEQ). The reliability of the translated instrument was assessed using Cronbach’s α. Chi-squared test was used to observe the chronotype distribution between the boys and girls. rMEQ scores of all the participants ranged between 5 and 25 with a median value of 17 (25–75th percentile: 15–20). Cronbach’s α was 0.751. Using cut off scores, we found 47% of our study participants were of morning chronotype, whereas the intermediate and evening types were of 50% and 3%, respectively. Chi-squared test demonstrated a significantly higher morningness among boys than the girls. The study describes the morningness orientation pattern of the Bengalese adolescents that may have some defined influence on their physiological and psychological characteristics including health and disease.This study was partially supported by the unrestricted internal research grant of the Allergy & Asthma Research Centre, Kolkat

Prevalence and risk factors of asthma and allergy-related diseases among adolescents (PERFORMANCE) study: rationale and methods

Despite a considerable number of international reports on allergic diseases among children, information about the prevalence and risk factors of asthma and allergy-related diseases among Indian adolescents is relatively sparse. The Prevalence and Risk Factors of Asthma and Allergy-Related Diseases among Adolescents (PERFORMANCE) study has been conceived to study the aetiology of asthma and allergic diseases including rhinoconjunctivitis, atopic eczema and food allergies among adolescents in West Bengal, India, using standardised methods and collaborations. The aims of the study are: 1) to estimate the prevalence and risk factors of asthma and allergic diseases among the adolescents residing in rural, suburban and urban areas of West Bengal; 2) to obtain information about the possible role of lifestyle factors (smoking, diet and physical activity) on the disease prevalence; and 3) to create a network for further investigation on social, environmental and genetic factors affecting the diseases. The PERFORMANCE study comprises two phases. The phase I study will investigate the prevalence and possible contributing factors of asthma and allergic diseases in a defined population. The phase II study will be performed as a follow-up of phase I to assess the incidence of asthma and allergic diseases

Influence of light at night on allergic diseases:a systematic review and meta-analysis

BACKGROUND: Allergic diseases impose a significant global disease burden, however, the influence of light at night exposure on these diseases in humans has not been comprehensively assessed. We aimed to summarize available evidence considering the association between light at night exposure and major allergic diseases through a systematic review and meta-analysis.METHODS: We completed a search of six databases, two registries, and Google Scholar from inception until December 15, 2023, and included studies that investigated the influence of artificial light at night (ALAN, high vs. low exposure), chronotype (evening vs. morning chronotype), or shift work (night vs. day shift work) on allergic disease outcomes (asthma, allergic rhinitis, and skin allergies). We performed inverse-variance random-effects meta-analyses to examine the association between the exposures (ALAN exposure, chronotype, or shiftwork) and these allergic outcomes. Stratification analyses were conducted by exposure type, disease type, participant age, and geographical location along with sensitivity analyses to assess publication bias.RESULTS: We included 12 publications in our review. We found that exposure to light at night was associated with higher odds of allergic diseases, with the strongest association observed for ALAN exposure (OR: 1.88; 95% CI: 1.04 to 3.39), followed by evening chronotype (OR: 1.35; 95% CI: 0.98 to 1.87) and exposure to night shift work (OR: 1.33; 95% CI: 1.06 to 1.67). When analyses were stratified by disease types, light at night exposure was significantly associated with asthma (OR: 1.62; 95% CI: 1.19 to 2.20), allergic rhinitis (OR: 1.89; 95% CI: 1.60 to 2.24), and skin allergies (OR: 1.11; 95% CI: 1.09 to 1.91). We also found that the association between light at night exposure and allergic diseases was more profound in youth (OR: 1.63; 95% CI: 1.07 to 2.48) than adults (OR: 1.30; 95% CI: 1.03 to 1.63). Additionally, we observed significant geographical variations in the association between light at night exposure and allergic diseases.CONCLUSIONS: Light at night exposure was associated with a higher prevalence of allergic diseases, both in youth and adults. More long-term epidemiological and mechanistic research is required to understand the possible interactions between light at night and allergic diseases.</p
