This report provides an analysis of the Whitehall Study, examining its sampling frames, disease risk assessments, and the generalizability of its findings. The report reviews studies by Breeze et al., Marmot et al., and Chandola et al., exploring risk factors for cardiovascular disease (CVD) and the impact of socioeconomic status and work-related stress. It evaluates the feasibility of using different cohorts for CVD risk assessment, including the 45 and Up cohort and the Australian Longitudinal Study on Women’s Health, while also discussing the limitations of the studies. The report highlights the association between employment grade, socioeconomic disadvantages, work stress, and the incidence of coronary heart disease (CHD), emphasizing the importance of these factors in public health research. The report concludes by summarizing the key findings and their implications for understanding and addressing health disparities.
