Differences in Health Complaints among Taiwanese Workers in Different Occupational Categories

Objectives: The objectives of this study were to determine the prevalence of and differences in certain health complaints, including physical symptoms and psychological distress, among workers in different occupational categories and to explore the associations between occupational category and each complaint. Methods: A cross-sectional study was conducted using a self-administered questionnaire. A total of 1,628 workers representing seven occupational categories from ten companies in different industries submitted completed questionnaires. The self-administered questionnaire contained three parts: personal data, physical symptoms and psychological distress. Physical symptoms were measured using nine questions developed by a panel of ten general practitioners; the questions included nine common physical symptoms across main organ systems. Psychological distress was measured using the Chinese Health Questionnaire. Results: Muscle pain (44.7%) and dizziness (30.1%) were the most common symptoms reported by participants, and 16.6% of participants suffered from psychological distress. Significant differences in physical symptoms and psychological distress were found among workers in different occupational categories (χ2=53.59, p<0.001). Compared with service workers, office workers and managers had higher prevalence rates of physical symptoms; office workers also showed a higher preva-lence of psychological distress. Conclusions: The study merits attention in terms of prevention of health problems in the workplace by focusing on a set of physical symptoms and psychological distress (not merely morbidity). Occupational category should be taken into consideration when planning workplace health promotion. Our findings highlight the need for health promotion programs that specifically target office workers and managers.
