Ashford HPR 350 Introduction to Epidemiology Week 2 Quiz Answers (2021)
Which form of prevention takes place after the precursors of disease interact with the host?
Using epidemiology for operational research involves:
The National Ambulatory Medical Care Survey is a continuing probability survey of physicians who practice in public settings such as V.A. centers.
Doll and Peto demonstrated that the mortality ratios for lung cancer were similar among those who smoked 1-14 and those who smoked 15-24 cigarettes per day.
Certain diseases can occur more than once in the same individual during a stated period of time. Repeated cases of the disease have no effect upon incidence rates.
According to the natural history of disease model, the time before the precursors of disease and the host interact is called the period of:
Increases in lung cancer mortality, especially among women, illustrate which of the following trends in disease occurrence?
The phases of the policy cycle include:
A prerequisite for using direct age adjustment is that the age-specific death rates in the study population must be stable.
For a chronic disease of low incidence and long duration, prevalence of the disease increases relative to incidence.
The criterion of plausibility refers to the existence of a dose-response relationship.
When the duration of a disease becomes short and the incidence is high, the prevalence becomes similar to incidence.
Beach City has a rising population of 500,000 robust, fertile males and 450,000 robust, fertile females. If there were 4,000 live births, 3 fetal deaths, and 40 maternal deaths, what is the crude birth rate?
The term health disparities refer to differences in health characteristics (e.g., mortality and burden of disease) that exist among specific U.S. population groups.
The incidence rate of a disease is defined as the number of new cases of the disease over a time period divided by the total population (at risk) during the same time period times a multiplier (e.g. 100,000).
An epidemiologic survey of roller-skating injuries in Metroville, a city with a population of 100,000 (during the midpoint of the year), produced the following data for a particular year:
Which of the following terms is expressed as a proportion (as distinguished from a ratio)?
Incidence and prevalence data have different applications in public health. Indicate by choosing the appropriate option whether the use below is for incidence or prevalence data:
Blood pressure measurements on adult males 30-39 years of age were obtained in a survey of a representative sample of Twin Cities households. To compare the frequency of hypertension in the white and non-white population surveyed, the most appropriate measure is the:
Different measures of disease are useful to evaluate and assess public health programs and needs in different situations. For each of the following questions, match the measure that would best support the listed goals.
