HOMEWORK #2 Question 2. From two hypothetical populations in city Zeta, data were occurrence of chronic bronchitis among males aged 40-79. The results are the following table. obtained on the shown in South Zeta No. male No, with North Zeta Total number No. with of males Age chronic bronchitis 30 chronic 40-49 50-59 60-69 70-79 TOTAL 2,000 4,000 3,000 10,000 10 20 50 30 2,000 2,000 2,000 3,000 20 20 20 90 110 2. 1What are the crude rates of Chronic Bronchitis in North and South 2. 2.Perform an age standardization comparison between the two populations with the following weights: 40-49 2,000; 50-59 1,000: 60-69 1,000; and 70-79 1,000. Where is the overall risk for Chronic Bronchitis (COPD) higher, in North or South Zeta? 2.3.Based on what type of rate did you answer question 2.2.? 2.4.Tobacco smoking is the number 1 risk factor for chronic bronchitis. Where would you presume that younger adults (younger than 50) smoke more? In North Zeta or South Zeta? Based on what type of rate did you answer your question? Question 3. In the context of epidemiological trends: 3.1.- The fact that the number of cancer cases increases with a population life expectancy can be described as mostly a result of a -effect. 3.2-When different graduating classes show sustained differences between them in the prevalence of marijuana consumption over time, these trends can be described as mostly a result of a -effect 1990s, concomitant with the discovery of the PSA test, is a proper description of a trend resulting mostly from a -effect. 3.3- The sudden peak in incidence of prostate cancer across all age groups in the earlyExplanation / Answer
The crude rate of chronic bronchitis in North Zeta is 110/10,000=0.011; the crude rate of chronic bronchitis in South Zeta is =90/9000=0.01.
For population below 50 north zeta has the rate 10/1000= 0.01 and south zeta has 30/2000= 0.015. therefore, south zeta has more chronic cases.
