Summary
This study developed and validated a questionnaire to assess lifestyle and diabetes knowledge in diverse communities. The tool effectively measures changes and identifies individuals at higher risk for type 2 diabetes.
Area of Science:
- Public Health
- Epidemiology
- Health Behavior
Background:
- Primary prevention of type 2 diabetes is achievable through lifestyle modifications.
- Population-level strategies are crucial for diabetes prevention.
- The South Auckland Diabetes Project developed a program to address diabetes awareness and healthy lifestyles.
Purpose of the Study:
- To develop and evaluate a questionnaire assessing the impact of a diabetes awareness and healthy lifestyle program.
- To assess diabetes knowledge and dietary habits in diverse ethnic groups.
- To provide a tool for evaluating population-based interventions for type 2 diabetes prevention.
Main Methods:
- An interviewer-directed questionnaire was administered to European, Maori, and Pacific Islands adults.
- Diabetes knowledge was assessed using open and closed questions, with reliability and validity analyses conducted.
- Dietary habits were evaluated using a fat index, high-fat/high-carbohydrate score, food frequency questionnaire, and fruit consumption questions.
Main Results:
- The questionnaire demonstrated good reliability, reproducibility, and external validity across ethnic groups.
- Diabetes knowledge scores increased post-intervention and were higher in individuals with diabetes or family history.
- Dietary assessment tools showed good reliability and correlation with dietetic assessments, with some inverse correlation between fruit intake and fat consumption.
Conclusions:
- The developed questionnaire is a rapid and effective tool for evaluating lifestyle and diabetes awareness interventions.
- It can be used to assess the impact of programs aimed at preventing and controlling type 2 diabetes.
- The tool is suitable for use across diverse ethnic populations in community settings.

30
DefinitionDiabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes mellitus, characterized by a triad of hyperglycemia (blood glucose >250 mg/dL), ketonemia or ketonuria, and metabolic acidosis (arterial pH <7.30 and serum bicarbonate <18 mEq/L). It results from insulin deficiency combined with elevated levels of counterregulatory hormones—glucagon, catecholamines, cortisol, and growth hormone—leading to increased lipolysis, hepatic...

30
Diabetic ketoacidosis (DKA) is a metabolic emergency characterized by hyperglycemia, ketonemia, and metabolic acidosis. It results from severe insulin deficiency and an excess of counterregulatory hormones, leading to uncontrolled lipolysis, ketogenesis, and widespread electrolyte and fluid disturbances.Pathophysiology The central event in DKA is a profound loss of insulin action. Without insulin, glucose uptake in insulin-dependent tissues is impaired, while hepatic glucose production...

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...

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...

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...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
