A method for the epidemiologic study of early diabetes

Area of Science:

• Endocrinology
• Public Health
• Epidemiology

Background:

• Diabetes mellitus is a significant public health concern.
• Early detection and screening are crucial for managing diabetes.
• Understanding screening test performance is vital for effective public health strategies.

Purpose of the Study:

• To evaluate a screening protocol for diabetes mellitus.
• To assess the utility of questionnaires and blood glucose levels in identifying potential diabetes cases.
• To determine the prevalence of diabetic glucose tolerance tests among individuals with positive screening results.

Main Methods:

• A survey of 4048 working adults included medical history and capillary blood glucose measurements.
• Screening criteria included elevated blood glucose and/or specific questionnaire responses.
• Diagnostic glucose tolerance tests were performed on eligible positive screens.

Main Results:

• 267 individuals (6.6%) had positive screening results.
• Positive screens were attributed to elevated glucose (n=67), questionnaire history (n=179), or both (n=21).
• Glucose tolerance tests revealed diabetic curves in 18%, 6%, and 33% of these respective screening categories.

Conclusions:

• Questionnaire-based screening for diabetes identifies a substantial group needing further investigation.
• The high proportion of positive screens based on history alone warrants consideration in future diabetes natural history studies.
• This screening approach highlights the importance of comprehensive assessment in diabetes detection.
