Abstract
Considering all of the tools, techniques, important (recent) reviews and interventions used in different studies, it has been obvious that there is now a worldwide epidemic of Type 2 Diabetes Mellitus, and the greatest increases are being seen in developing countries, unless appropriate action is taken, it is predicted that number of diabetic patients will replicate rapidly.
Effective treatments are available but there is no known cure. The focus therefore is on both prevention and early detection by screening, with a view to preventing or delaying complications.
The issue of screening for type2 diabetes is important both in terms of individual health, day-to-day clinical practice and public health policy, however screening for type2 diabetes is a dynamic topic in which new evidence will become available and further considerations will arise over time.
There is direct evidence that the incidence of diabetes can be reduced in people at high risk of the future development of type2 diabetes who may be identified as a result of activities directed towards diabetes detection with screening programs which will lead to enhanced length and quality of life which might result from a reduction in the severity and frequency of the immediate effects of diabetes or the prevention or delay of its long-term complications, Also redistribution of health care resources which might be possible as a result of reduced levels of care required for diabetes complications (reduced hospital admissions and lengths of stay etc.,.
Recommended targeted case finding of type2 diabetes, according to the important (recent) reviews are;
• Testing for diabetes should be considered in all individuals at age 45 years and above, particularly in those with a BMI of 25 or over, and if normal should be repeated at 3-year intervals.
• Testing should be considered at a younger age or be carried out more frequently in individuals who are overweight (BMI >25) and have additional risk factors, as follows:
● are habitually physically inactive
● have a first degree relative with diabetes
● are members of a high-risk ethnic population
● have delivered a baby weighing >9 lb. or have been diagnosed with GDM
● are hypertensive (>140/90)
● on previous testing, had IGT or IFG
● have history of vascular disease.
The ADA said that either an FPG or a 2-hour OGTT (75 g) was appropriate, as a screening test for diabetes [8], (ADA), (IDF) and the European Association for the Study of Diabetes (EASD) recommended the use of the HbA1C test to diagnose diabetes, with a threshold of ≥ 6.5%.
Clinical opportunistic screening in family practice offers an important alternative approach since it may well be more cost-effective, provides the quickest route to treatment, and can detect two-thirds of all new cases of Type 2 Diabetes in a defined population. Since Type 2 Diabetes is increasingly managed in family practice or primary care, education and support is important.
