Please be aware that it is difficult to program answers for every possible calculation variation that the students may offer while still being “correct.”   For example, the exact answer rounded to three decimal places may be 0.781.  Students may still work the problem correctly, but round in their steps.  They may get 0.782 or 0.780 etc….  There may also be typos and spelling errors.   For these reasons, correct answers may be marked as incorrect initially.  I do review the tests and try to correct these errors.  Don’t panic until I have reviewed the tests.

(3) Most researchers and health care professionals agree that body mass index (BMI) is useful on a population level to track weight changes and chronic disease risk. However, there is debate on if and how BMI should be used as a tool to assess obesity in individuals. The AMA adopted a new policy on the use of BMI in June 2023. This policy change, “recognizes issues with using BMI as a measurement due to its historical harm, its use for racist exclusion, and because BMI is based primarily on data collected from previous generations of non-Hispanic white populations.” (quote from linked article above). From your knowledge of research methods, what do you think about using non-Hispanic white populations to create BMI categories for individual assessment for obesity that are used for all race and ethnic groups? Describe why you agree or disagree with the argument made in the article against using BMI to assess individuals.

(4) The ASA24 is an internet-based automated self-administered 24-hour dietary recall application developed by NCI. It uses technology drawn from the USDA’s Automated Multiple-Pass Method to provide a tool to researchers, educators, and the public for collecting multiple 24hr recalls. The ASA24 has become a very popular method of data collection given that it can be used free of charge to investigators that register their research studies.  Describe the strengths and limitations of the ASA24 recall method and discuss whether or not it has been shown to be valid in adults and children.
