HPEX 358 Quizzes - Questions and Answers You want to examine the relationship between two variables, age and height. You can use all of the following methods to analyze this relationship except - Pe ... arson Correlation Coefficient (r) - contingency table - scatter plot - dose-response curve You wanted to examine the relationship between two variables age and height in the older population. After analyzing the data, you found that an increase in age was associated with a decrease in height in the older population. Which of the following statements regarding this association is true? - The association between age and height is always causal. - Age and height has a direct (positive) linear association in the older population. - Age and height has an association but it is not linear. - Age and height has an inverse (negative) linear association in the older population. Instead of using a single value for estimation, you want to use a range of values for the parameter estimation. You should use - 95% confidence interval - percentile - quartile - standard deviation When the incidence rate of a disease decreases, the prevalence will Decrease Which factor can increase an observed prevalence? - longer duration of disease - in-migration of healthy people - improved cure rates of disease - none of the above You want to know the number of women who died from breast cancer in the City of Richmond in 2019 among all the women who had breast cancer in the City of Richmond in the same year. The measure you should use is - crude death rate - case-fatality rate - cause-specific rate - none of the above If the number of deaths in a small county in Virginia in 2019 was 20 and the population there at the midpoint of 2019 was 10,000; what would be the crude death rate per 1,000 of the population of that county? 2 per 1,000 The number of live births in Richmond City during 2019 divided by the population of Richmond City during the midpoint of 2019 is the - general fertility rate - crude birth rate - perinatal fertility rate - specific birth rate The number of live births in Richmond city during 2019 divided by the women population of Richmond City in the age group of 15-44 years during the midpoint of 2019 is the - general fertility rate - crude birth rate - perinatal fertility rate - specific birth rate You have the following information about Richmond City for the year of 2019: the number of babies died under the age of 1 year, the number of fetuses died when they were in the uterus, the number of mothers died from causes associated with pregnancy, and the number of live births. You will be able to calculate all of the following rates except - maternal mortality rate - fetal mortality rate - proportional mortality rate - infant mortality rate A group of smokers and non-smokers were enrolled in a study of chronic lung diseases. During the five years of study period, the researchers lost some of the study participants. Therefore, the researchers followed the smokers and the non-smokers for 64,245 and 58,569 person-years, respectively. During the study period, 300 of the smokers and 100 of the non-smokers developed chronic lung diseases. Which morbidity measure should the researchers calculate? [Show More]
