Question 1

The nutritionist using an epidemiological triangle in a situation of obesity knows that it is a traditional model that explores health and disease using three components: host, agent, and environment. A change in any of the components will result in:

Accepted Answer

A change in any of the components of the epidemiological triangle (host, agent, or environment) can disrupt the balance and lead to disequilibrium, potentially resulting in health issues such as obesity.

Question 2

In which of the following research methods, are random sample surveys and structured interviews used to collect data (mostly quantifiable data) and analyzed using statistical techniques?

Accepted Answer

Quantitative research methods involve the collection and analysis of numerical data, often using random sample surveys and structured interviews, and the data is analyzed using statistical techniques.

Question 3

Which of the following is not true about a cohort study?

Accepted Answer

Cohort studies are typically large because they follow a group of people over time to assess the development of outcomes, such as diseases.

Question 4

Beth is a dietitian who wants to do some research in her community. She will be conducting random sample surveys to collect data from the community. She will analyze the data using statistical techniques that depend on isolation of one or more variables. What type of research method is this?

Accepted Answer

Beth is using quantitative research methods as she is collecting numerical data through surveys and analyzing it using statistical techniques, which is objective in nature.

Question 5

Which would be the best approach for Beth if she were trying to measure the level of poverty in her community?

Accepted Answer

Objective and structured interviews would provide Beth with consistent and reliable data to accurately measure the level of poverty in her community.

Question 6

In which type of study does the investigator have control over participants, procedures, and exposures?

Accepted Answer

In an experimental study, the investigator has control over the participants, procedures, and exposures, allowing them to manipulate variables to determine causal relationships.

Question 7

Demography is an analytical tool used to measure a population by recording characteristics such as:

Accepted Answer

Demography involves the statistical study of populations, including the recording and analysis of characteristics such as age, gender, and educational level.

Question 8

A researcher wants to investigate the effect of lipids on different nutrient utilization. He or she would conduct a metabolic diet study that would:

Accepted Answer

A metabolic diet study involves controlling and varying specific components of a diet to observe physiological or biological effects, rather than observing naturally occurring patterns in free-living populations.

Question 9

What is an analytical tool used to measure a population by recording births, deaths, age distribution, and other vital statistics?

Accepted Answer

Demography is the analytical tool used to measure and study populations by recording births, deaths, age distribution, and other vital statistics.

Question 10

Which of the following is expressed as a mathematical relationship in which the numerator is the number of persons experiencing the condition and the denominator is the population at risk.

Accepted Answer

The answer of Which of the following is expressed as...

Question 11

A community nutritionist utilizing the genetic epidemiological approach may use which of the following?

Accepted Answer

Molecular epidemiology is a field that combines genetic information with traditional epidemiological studies to understand the role of genetic factors in health and disease, making it relevant for a genetic epidemiological approach.

Question 12

Which of the following is an example of host factor in the epidemiological triangle model?

Accepted Answer

Host factors refer to the intrinsic characteristics of the individual, such as age, gender, and eating patterns, which can influence their susceptibility to disease.

Question 13

Efficient management of services without gaps or overlaps is the definition of:

Accepted Answer

Coordination refers to the organization of different elements or activities to ensure they work together effectively without gaps or overlaps.

Question 14

Which of the following research methods uses semistructured or interactive interviews to collect data?

Accepted Answer

Qualitative research methods use semistructured or interactive interviews to collect data, as they allow for flexibility and in-depth exploration of participants' experiences and perspectives.

Question 15

A community nutritionist can form a partnership with other healthcare professionals to complement his or her expertise. The four phases for successful partnership building in community-based research are:

Accepted Answer

The four phases for successful partnership building in community-based research are networking, cooperation, collaboration, and partnership.

Question 16

Cindy, a public health nutritionist, is using a cross-sectional research method to conduct her study. In cross-sectional research, the nutritionist:

Accepted Answer

Cross-sectional research involves observing or measuring a specific variable or outcome at a single point in time across a sample population.

Question 17

In which of the following types of studies is the aim is to identify the cause of a disease among a group of people, or the cause-effect relationships of the health condition?

Accepted Answer

Case-controlled studies aim to identify the cause of a disease by comparing individuals with the disease (cases) to those without it (controls) to find differences in exposure or risk factors.

Question 18

Demography is an analytical tool used to measure a population by recording different characteristics such as:

Accepted Answer

Demography involves the statistical study of populations, including the recording of characteristics such as age, gender, and educational level.

Question 19

Beth is a dietitian that wants to do some research in her community. She will be conducting random sample surveys to collect data from the community. She will analyze the data using statistical techniques that depend on isolation of one or more variables. What type of research method is this?

Accepted Answer

Beth's research involves collecting numerical data through surveys and analyzing it using statistical techniques, which is characteristic of quantitative and objective research methods.

Question 20

In testing the hypothesis, research observations have shown a direct relationship between higher sodium intake and higher blood pressure across population groups.

Accepted Answer

Research has consistently demonstrated that increased sodium intake is associated with elevated blood pressure, a relationship observed across various population groups.
