Lifting capacity prediction model using physical performance measures among construction workers.

Manual materials handling is performed in many workplaces and is a significant risk factor for musculoskeletal injuries. The identification of lifting capacity is important to reduce the occurrence of musculoskeletal injuries. Lifting capacity is difficult to evaluate at the workplace. Therefore, there is a need to develop an alternate method that is easy and could be performed at the workplace. The study aimed to develop a lifting capacity prediction model for construction workers based on muscle strength and endurance. In this study, 65 construction workers were recruited; their socio-demographic and physical characteristics like core strength and endurance, grip strength, and lower limb flexibility were assessed. The lifting capacity was assessed using progressive isoinertial lifting evaluation. Stepwise multiple linear regression was carried out to develop the prediction model. The study suggested that age, BMI, grip strength, flexibility, prone plank, and trunk lateral flexor endurance tests have significantly influenced lifting capacity. Hence prediction model is developed using these variables. The regression model developed would help in easy estimation of lifting capacity among construction workers, which could be even administered with minimal skills by site supervisors or managers. It might help in the decision-making during pre-placement or return to work evaluations, thereby minimizing the incidence of low back disorders.

"Occupational sitting kills; but who cares?": Quantitative analysis of barriers and facilitators of sedentary behavior in Indian white-collar workers.

The knowledge, attitude and practices of employees and employers toward reducing sedentary behavior (SB) and improving physical activity (PA) at Indian workplaces remain unclear. A bespoke questionnaire assessing barriers and facilitators of occupational SB and PA practices as informed by the theoretical framework and behavioral change wheel model was adapted. Two hundred and three white-collar workers (both employees and managers) from eight corporate sectors were inquired about the SB, and PA practices at workplaces. The dichotomous variables of barriers and facilitators were analyzed by nonparametric tests. Excessive sitters had good knowledge (>75%), good attitude (>85%) but poor workplace SB and PA practice (>90%). Workplace SB, or PA practices differed between employers and employees. Low practice of workplace PA or SB interventions may be due to lack of workplace policies for SB interventions.

Hazards and Health Risks Encountered by Manual Sand Dredgers from Udupi, India: A Cross-sectional Study.

INTRODUCTION: Globalization and urbanization have resulted in an increased demand on sand dredging. Legal and environmental restrictions on automated dredging have led to a rise in manual technique. The working techniques and environment involved in manual sand dredging may expose the workers to multiple work related disorders. AIM: To determine the health risks and occupational hazards involved in manual sand dredging. MATERIALS AND METHODS: An assessment schedule was developed and content was validated by five experts for the study. A cross-sectional study was then conducted using this assessment schedule. Thirty manual sand dredgers were recruited from three randomly selected docks on Swarna riverbed in Udupi district, Karnataka, India. A detailed work and worksite assessments were conducted using systematic observation and close-ended questions. Work-related health risk evaluation included onsite-evaluation and self-reported health complains. RESULTS: The prevalence of musculoskeletal pain and discomfort was 93.34% with lower back (70%), shoulder (56.7%) and neck (46.7%) involvements being most common regions. Prevalence of sensory deficits at multiple site and ear pain was 66.6% and 76.6% respectively. All the workers recruited, complained of dermatological and ophthalmic involvements. Also, lack of health and safety measures like personal protective devices and security schemes were identified. CONCLUSION: This study shows a high prevalence of multiple work-related disorders and hazards involved in manual sand dredging, a highly demanding job in coastal Karnataka. Lack of health and safety measures were also identified.

Barriers Encountered by Accredited Social Health Activists (ASHA) in Arthritis Rehabilitation: A Qualitative Study.

INTRODUCTION: Healthy behaviour through education of individuals with arthritis is the mainstay of long term management. Time and access constraints restrict medical professionals from active involvement in arthritis education in the community. Reaching the community through the Accredited Social Health Activists (ASHAs) is the plan of action operational in India. Hence, the factors encountered by ASHAs while delivering arthritis education programs need to be studied. AIM: The aim of the study was to explore the experiences of ASHAs while delivering arthritis education program. MATERIALS AND METHODS: Qualitative exploratory design employing semi-structured interviews was adapted for the study. The interviews were conducted using focus groups of ASHAs from two geographically similar villages. Inductive analysis of focus group discussions was undertaken to determine themes, categories and codes. RESULTS: Three broad themes were identified from the interviews which influenced the performance of ASHAs. Categories identified show the influence of training, characteristics of ASHAs, geographical features, family characteristics and community attitude. Few problems reported were means of transport, time constraints, multiple tasks, type of incentive and frequency of on-field demonstrations. CONCLUSION: Providing motivation for altruistic services has always been a challenge to governing bodies. The issues identified in this study can be addressed prior to integrating ASHAs for rehabilitation services.
