This study will analyze two nationally representative longitudinal surveys - the 1979 cohort of the National Longitudinal Survey of Youth (NLSY79), and the Health and Retirement Study (HRS). While the NLSY79 covers the teenage to middle-aged years, the HRS covers workers’ lives near and after retirement. Both of the surveys collect detailed information on work history, demographics, socioeconomic status, and health (e.g., work-related injuries). The HRS also includes a special module for “Occupational Injuries” which collects information on OSHA inspections at job sites and certain workplace exposures. In addition, these two surveys are designed to collect information on the general population. Thus, we will be able to examine work-related injuries and illnesses in self-employed workers, retired workers, and other workers who are excluded or underrepresented in current BLS injury and illness reports and workers’ compensation systems. Key determinants and findings from this study will serve as an evidence-based guide to preventions and interventions to minimize chronic diseases and disabilities within the construction workforce, and improve Working Life Expectancy (WLE) starting from an early age. The outcomes will also highlight the benefits of safer and healthier work environments and behaviors, and promote a safety and health culture in the construction industry.
