Question 2

Which one of the following statements is True about the Ten-State Nutrition Survey?

Accepted Answer

The Ten-State Nutrition Survey, conducted in the late 1960s and early 1970s, highlighted nutritional deficiencies in certain populations, leading to the development of the National Health and Nutrition Examination Survey (NHANES).

Question 3

Food availability data are derived from

Accepted Answer

The balance sheet approach is the most commonly used method for deriving food availability data. It involves subtracting food imports and exports from the national food supply to estimate the amount of food available for consumption in a particular country or region. This method is widely used by international organizations such as the FAO and the World Bank to assess food security and nutrition status. The other options listed are methods used to collect individual-level dietary intake data, which are different from population-level food availability data.

Question 4

Estimates of the prevalence of overweight and obesity in the United States based on data collected by the Behavioral Risk Factor Surveillance System are likely to __________ the True prevalence of overweight and obesity in the U.S.

Accepted Answer

The Behavioral Risk Factor Surveillance System relies on self-reported data, which often leads to underreporting of weight and overreporting of height, resulting in an underestimation of the true prevalence of overweight and obesity.

Question 5

Which one of the following is responsible for measuring food security in the United States?

Accepted Answer

The U.S. Department of Agriculture (USDA) is responsible for measuring food security in the United States through its annual food security survey. This survey measures both household food security and individual food security.

Question 6

Which one of the following statements is True? The National Health Examination Survey

Accepted Answer

The National Health Examination Survey was conducted before the National Health and Nutrition Examination Survey began. The National Health Examination Survey was conducted from 1960 to 1962, while the National Health and Nutrition Examination Survey began in the early 1960s but did not become a continuous program until 1999.

Question 7

The earliest efforts at nutritional monitoring in the United States were carried out by the

Accepted Answer

The earliest efforts at nutritional monitoring in the United States were carried out by the USDA, specifically through the creation of the Bureau of Home Economics in 1923. The other options listed, Centers for Disease Control and Prevention (A), National Academy of Sciences (B), and USDHHS (D), were established many years later and were not involved in the earliest monitoring efforts.

Question 8

"Health: United States," published annually by the National Center for Health Statistics, is an example of the type of publication mandated by the National Nutritional Monitoring and Related Research Program, which requires timely dissemination of data on the dietary, nutritional, and health related status of the U.S. population.

Accepted Answer

The statement accurately describes the relationship between "Health: United States" and the mandate of the National Nutritional Monitoring and Related Research Program.

Question 9

Which one of the following is responsible for conducting the Behavioral Risk Factor Surveillance System?

Accepted Answer

The Behavioral Risk Factor Surveillance System (BRFSS) is a survey conducted by the Centers for Disease Control and Prevention (CDC), which is an agency within the U.S. Department of Health and Human Services. Therefore, choice B is the correct answer.

Question 10

In the National Health and Nutrition Examination Survey, older participants have

Accepted Answer

Older participants in the National Health and Nutrition Examination Survey typically have a more extensive examination compared to younger participants. This is because they are more likely to have age-related health conditions that require additional testing and monitoring.

Question 11

Prior to passage of the National Nutrition Monitoring & Related Research Act of 1990, the U.S. Department of Health and Human Services had not been involved in the nutritional monitoring of the U.S. population.

Accepted Answer

Prior to the National Nutrition Monitoring & Related Research Act of 1990, the U.S. Department of Health and Human Services had been involved in the nutritional monitoring of the U.S. population through the publication of the Dietary Goals for the United States in 1977 and the establishment of the National Center for Health Statistics in 1960.

Question 12

The National Health and Nutrition Examination Survey is a continuous, on-going survey conducted annually.

Accepted Answer

The answer of The National Health and Nutrition Examination Survey...

Question 13

Unless adjusted for losses, food availability data tend to _________ actual food and nutrient consumption.

Accepted Answer

Food availability data refer to the amount of food that is available in a country or region, and do not take into account losses that occur between production and consumption, such as spoilage, waste, and theft. Therefore, food availability data tend to overestimate actual food and nutrient consumption.

Question 14

Consider self-reported data on height and weight obtained using telephone interviews. Which one of following statements is True?

Accepted Answer

Self-reported data on height and weight obtained using telephone interviews tend to underestimate the True prevalence of overweight and obesity in the sample. People tend to overestimate their height and underestimate their weight, leading to an underestimation of body mass index (BMI) and a potential misclassification of overweight or obesity status. This phenomenon is known as social desirability bias, where individuals respond in a way that is perceived as more socially acceptable, rather than providing accurate information.

Question 15

Which one of the following is responsible for maintaining nutrient databases in the United States?

Accepted Answer

The U.S. Department of Agriculture is responsible for maintaining nutrient databases in the United States, including the USDA National Nutrient Database for Standard Reference.

Question 16

Strengths of food availability data are that they provide information on patterns of food consumption over time and are the only source of information on food and nutrient trends since the beginning of the twentieth century.

Accepted Answer

Food availability data is a valuable source of information on long-term patterns of food consumption, and they are the only available source of information on food and nutrient trends that stretch back over a century. Therefore, this statement is true.

Question 17

A research arm of Congress that audits government programs and highlights areas of waste and fraud is the

Accepted Answer

The Government Accountability Office (GAO) is a research arm of Congress that audits government programs and highlights areas of waste and fraud. The other options, such as the Federation of American Societies for Experimental Biology, Food Surveys Research Group, and National Technical Information Service, are not related to government accountability, waste, or fraud.

Question 18

The purpose of the USDA's Supplemental Children's Survey is to gather the necessary data for updating the CDC's pediatric growth charts.

Accepted Answer

The USDA's Supplemental Children's Survey is not responsible for gathering data to update the CDC's pediatric growth charts. The CDC's growth charts are typically updated based on data from the National Health and Nutrition Examination Survey (NHANES), which is conducted by the CDC's National Center for Health Statistics.

Question 19

Which of the following is another name for what is now referred to as What We Eat in America?

Accepted Answer

The "What We Eat in America" is the dietary intake component of the National Health and Nutrition Examination Survey (NHANES).

Question 20

Annual per capita availability of which one of the following beverages is greatest?

Accepted Answer

Carbonated soft drinks have the highest annual per capita availability compared to beer, coffee, and milk, due to their widespread consumption and popularity.
