Part A
Answer 1
According to Breeze et al., (2001) the sampling frame used for the white hall study
was resurveying the survivors of the Whitehall cohort study who were aged between 40 to 69
years of age. Smaller sample size and the large variable range was chosen for this study.
Whitehall, I included male British civil servants as the sampling frame which showed a high
mortality gradient and Whitehall II was a resurvey conducted as stated in the previous

Answer 2
According to Marmot et al., (1978), it can be stated that the authors assessed the
disease (Coronary Heart Disease- CHD) among various grades of workers. The findings
suggested that lower grade workers had 3 to 6 times higher mortality rates than men from the
highest employment grade. They used a longitudinal study of 7350 civil servants who are
working in London to assess the risk of disease at various levels of employment.
According to Chandola et al., (2008) it can be stated that for the determination of
behavioural and biological factors they performed a mechanism-based study on the Whitehall
II study. The authors used a risk ration cross-sectional study to analyze the underlying
mechanisms for the underlying CHD among the sample population.
Breeze et al., (2001), collected data from 19029 men with most of the men aged
between 40 to 69 years. The time frame used for the data collection purpose was 1967 to
1970. A questionnaire concerning medical histories and job-related factors were given to the
participants, filling up of which resulted in the data analysis process. Whereas, the Whitehall
study II conducted a resurvey on the 400 survivors of study I in the year 1996. The data
analysis process used for this paper was Chi-square heterogeneity analysis required for
