Rationale of the Week | Why do we celebrate World Diabetes Day on Nov 14th?

For last week’s practice question, we quizzed participants on why we celebrate World Diabetes Day on Nov 14th. 39% of respondents chose the best answer. We want to clarify and share this important information, so you can pass it on to people living with diabetes and your colleagues, plus prepare for exam success!

Before we start though, if you don’t want any spoilers and haven’t tried the question yet, you can answer it below: Answer Question

Question: In 1923, the Nobel prize in Physiology or Medicine was awarded to Frederick Grant Banting and John James Richard MacLeod “for the discovery of insulin”.  100 years later, we celebrate this life-saving discovery each year on November 14th, a day designated as World Diabetes Day.

Why do we celebrate World Diabetes Day on November 14th? Please choose the best answer.

Answer Choices:

  1. It was the date the Nobel Prize was awarded to Dr. Banting and Dr. MacLeod.
  2. It signifies the production date of the first vial of insulin.
  3. It commemorates the opening date of the Banting Museum in Canada.
  4. It is the birthday of Sir Frederick Banting.

Getting to the Best Answer

If you are thinking about taking the certification exam, this practice test question will set you up for success. Test writers anticipate possible answers based on the details in the question. They will wave those “juicy answers” right under your nose. Your job is to weed through the particulars, pluck out the most important elements, and choose the BEST answer.

Answer 1 is incorrect. 28.42% chose this answer. “It was the date the Nobel Prize was awarded to Dr. Banting and Dr. MacLeod.” This is not the reason, however it is interesting to note that the Nobel prize for the discovery of insulin was awarded on December 10, 1923 in Stockholm, Sweden.

Answer 2 is incorrect. 27.89% of you chose this answer. “It signifies the production date of the first vial of insulin.” Great guess. However, it wasn’t until 1923 that the first vials of insulin were commercially produced and distributed.

Answer 3 is incorrect. About 4.74% of respondents chose this. “It commemorates the opening date of the Banting Museum in Canada.” The Banting House is a former residence and current museum in London, Ontario, Canada, known as the “Birthplace of Insulin.” It is the house where Sir Frederick Banting woke up at two o’clock in the morning on October 31, 1920 with the idea that led to the discovery of insulin. Since 1984, the house has been a museum dedicated to Banting’s discovery and his life.

Finally, Answer 4 is correct. 38.95% chose this answer. “It is the birthday of Sir Frederick Banting.” YES, this is the best answer. Dr. Banting was born on November 14, 1891.  That is why we celebrate World Diabetes Day on November 14th.

World Diabetes Day Celebrates Dr. Banting’s Birthday and the Discovery of Insulin!

We hope you appreciate this week’s rationale! Thank you so much for taking the time to answer our Question of the Week and participate in this fun learning activity!


National Diabetes Month

November kicks off National Diabetes Month, a time to recognize that over 11% of Americans are living with diabetes and over 35% have prediabetes. Since diabetes results from a combination of genetics plus environment, there is a recognition that social determinants of health play a pivotal role in the development of diabetes and its complications. Through advocacy and education, we can inform individuals on best care for diabetes and support them in taking action to improve the health of their communities to prevent future diabetes. We have put together a list of FREE diabetes resources in English and Spanish to share with people living with prediabetes and diabetes. Thank you for your advocacy and belief that we can make a difference. Coach Beverly
