Insights

Community screenings effectively identified undiagnosed diabetes and at-risk individuals in urban immigrant populations. Hemoglobin A1c (HbA1c) proved a valuable tool for detecting diabetes and cardiovascular disease risk.

Area of Science:

  • Community Health
  • Preventive Medicine
  • Endocrinology

Background:

  • Inner-city immigrant and mixed-ethnic communities face high risks for cardiovascular disease and diabetes.
  • These populations may have limited access to preventive healthcare services.
  • Hemoglobin A1c (HbA1c) was investigated as a potential screening tool for diabetes and related conditions.

Purpose of the Study:

  • To evaluate the utility of HbA1c screening in a community-based program.
  • To identify new cases of diabetes and individuals at risk for diabetes and cardiovascular disease.
  • To analyze the correlation between HbA1c levels and other health indicators.

Main Methods:

  • Screenings conducted in diverse community settings (churches, shelters, street corners) in the Bronx.
  • Collected data included HbA1c, random glucose, lipid profile, blood pressure, BMI, age, and ethnicity.
  • Analyzed data for diabetes prevalence (HbA1c ≥7%) and risk (HbA1c 6%-6.99%), and associations with other variables.

Main Results:

  • Out of 539 participants, 11.4% had HbA1c >7% (undiagnosed diabetes) and 32% had HbA1c >6% (at risk).
  • HbA1c correlated more strongly with cardiovascular risk factors (cholesterol, triglycerides, blood pressure, BMI) than random glucose.
  • Higher HbA1c levels were observed in the South Bronx, correlating with higher poverty rates.

Conclusions:

  • A high prevalence of undiagnosed diabetes and individuals at risk was found in this urban community setting.
  • Community-based HbA1c screening is an effective method for identifying high-risk individuals in diverse inner-city populations.
  • HbA1c screening can facilitate early detection and intervention for diabetes and cardiovascular disease.

Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis

Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
Hyperglycemia01:29

Hyperglycemia

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is based on...

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Assessment of the Cardiovascular System I: Subjective Data

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
