Terms and Definitions

Prevalence refers to the total number of individuals in a population who have a specific disease or condition at a specific point or period. It is usually given as a percentage or proportion of the population considered.

Diabetes is a chronic disease characterized by the body's inability to effectively use the insulin it produces, or due to insufficient production of insulin. This condition results in elevated levels of glucose in the blood, known as hyperglycemia. It can lead to serious health complications such as heart disease, kidney failure, and loss of vision.

The term 'seniors' is used to refer to adults who are generally at retirement age or older. Although it can vary by context, in general, it is often used to refer to individuals who are 65 years of age or older.

A year-by-year analysis involves breaking down data per annum to analyze trends or changes over time. It is especially useful in comparing changes in prevalence rates over years and drawing conclusions from such comparisons.

Type 1 diabetes, also known as juvenile diabetes, is an autoimmune condition wherein the body's immune system attacks and destroys insulin-producing cells in the pancreas. This results in the body not being able to produce insulin, leading to high blood sugar levels.

Type 2 diabetes is a chronic condition that affects how the body metabolizes sugar (glucose), resulting in the body either resisting the effects of insulin or not producing enough insulin. It is the most common type of diabetes and is often associated with obesity and a sedentary lifestyle.

Gestational diabetes is a condition that affects pregnant women during their pregnancy. This form of diabetes causes high blood sugar that can affect pregnancy and the baby's health, but typically it resolves after childbirth.

Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. It allows cells to take in glucose from the bloodstream and use it as a source of energy, helps store excess glucose in the liver, and keeps blood sugar levels from getting too high or low.

Hyperglycemia refers to a condition where there is an excessive amount of glucose circulating in the blood plasma. This condition is commonly associated with diabetes and can lead to severe complications if left untreated over time.
