Occupational stress is a critical health concern across various professions, often linked to adverse health outcomes and increased risk-taking behaviors. Bus drivers are especially vulnerable due to prolonged shifts, exposure to environmental pollutants, and higher rates of sickness absenteeism. This study aimed to assess the prevalence of occupational stress among Karnataka State Road Transport Corporation (KSRTC) bus drivers and the factors contributed. In addition, it explores the relationship between job-related stress and overall health status, providing insights into the occupational challenges faced by this workforce. A cross-sectional study was conducted over two years from June 1, 2022, to June 30, 2024, at the KSRTC depot in Kolar, serving urban and rural areas. A representative sample of 235 bus drivers was selected from a total of 654 using simple random sampling. Socio-demographic details, including age, gender, education, religion, family type, and per capita income, were collected using a pre-tested semi-structured self-administered questionnaire. Stress levels were assessed using the American Institute of Stress (AIS) questionnaire, a widely used tool for evaluating various stress dimensions. Data were collected through interviews, entered into Excel, and subsequently analyzed using IBM SPSS Statistics for Windows, Version 22 (Released 2013; IBM Corp., Armonk, New York, United States). The study revealed that 65% of KSRTC bus drivers experienced moderate to severe stress. Significant factors associated with occupational stress included urban residency, divorce, chronic alcohol consumption, current tobacco chewing, hypertension, higher BMI, long working hours, and high waist-hip ratio. Binary logistic regression showed urban residents had higher stress odds than rural residents (OR=1.27, p=0.03). Divorced individuals and chronic alcoholics also had higher odds of stress (OR=1.24, p=0.05 and OR=1.33, p=0.04, respectively). Stress was significantly associated with hypertension (OR=1.40, p=0.01), obesity (OR=1.30, p=0.03), morbid obesity (OR=1.47, p=0.01), high-risk waist-hip ratios (OR=1.42, p=0.01), and longer working hours (>12 hours, OR=1.30, p=0.03). Health assessments revealed a high prevalence of hypertension (39%) and obesity (65%). The study highlights a high prevalence of occupational stress among KSRTC bus drivers in Kolar, with 65% experiencing moderate to severe stress. Factors such as urban residency, lifestyle habits, and physiological parameters significantly contribute to stress. These findings underscore the need for targeted health promotion programs and policy changes to enhance the health of essential workers and improve road safety.
