Your Passage: Many years ago, Burr and Holliday performed a study that analyzed the dramatic difference in mortality rates involving lung disease in South Wales and England. It was determined that there was a significantly higher rate of respiratory disease and symptoms thereof in Wales compared to that of England. This specific study set out to find whether this drastic inconsistency correlated with the smoking patterns and social classes of each region. To begin this study, a sample of four hundred elderly men around the age of seventy was chosen from each region. The two regions specifically involved were Bath and Caerphilly. The subjects …show more content…

During the experiment the social classes of the individuals were divided into manual workers and non-manual workers. The FEV and FVC values were standardized and averaged for the subjects along with their ages. Overall, the FEV and FVC measurements were considerably higher for the men from Bath than those of the men from Caerphilly. Likewise, the FEV and FVC measurements were also higher for non-manual workers compared to those of manual workers. During the survey it was noted that Caerphilly had a much higher percentage of smokers in its region than in Bath. Because of this, it was speculated that smoking was the leading cause behind the greater occurrence of phlegm, coughing, and breathless wheezing in Caerphilly. According to Burr and Holliday, the standardized mortality ratio for males suffering from illnesses such as emphysema and bronchitis is much higher in Wales than in Bath. They noted other possible factors that could have influenced this statistic such as damp climate, pollution, coal mining history, and selective migration of a healthier population. Nevertheless, they followed this with the conclusion that none of these factors weigh as heavily into the occurrence of lung
