Integrated Diabetes and Oral Health Care in Oman

2026年9月2日 更新者：Oman Ministry of Health

Cost-Effectiveness and Implementation of Integrated Diabetes-Oral Health Care in Oman: A Health Belief Model-Based Intervention to Enhance Clinical, Behavioral, and Exploratory Oral Microbiome in Health System Outcomes in Type 2 Diabetes

Type 2 diabetes mellitus (T2DM) and periodontal (gum) disease are closely related conditions that may negatively affect each other. However, oral health is not routinely integrated into diabetes self-management education. This study will evaluate whether a structured diabetes-oral health educational intervention based on the Health Belief Model can improve glycaemic control, periodontal health, self-management behaviours, and quality of life among adults with T2DM in Oman.

This multicentre randomized controlled trial will include 290 adults with T2DM. Participants will be randomly assigned to either an intervention group or a control group. The intervention group will receive six individual, structured diabetes-oral health education sessions over 12 weeks in addition to usual care. The control group will continue to receive standard diabetes care and education.

Participants will be followed for 12 months. The primary outcome is change in glycated haemoglobin (HbA1c) from baseline to 12 months. Secondary outcomes include periodontal health, diabetes and oral-health self-care behaviours, Health Belief Model constructs, quality of life, psychological well-being, diabetes distress, healthcare utilization, and healthcare costs. The study will also assess the cost-effectiveness of the intervention. Exploratory components will assess previously undiagnosed periodontal disease and examine associations between periodontal changes and the oral microbiome.

详细说明

Type 2 diabetes mellitus (T2DM) is an important public health problem in Oman. Periodontal disease is common among people with diabetes, and the relationship between diabetes and periodontal disease is bidirectional. Poor glycaemic control may contribute to periodontal inflammation, while periodontal inflammation may adversely affect metabolic control. Despite this relationship, diabetes education commonly focuses on glycaemic control and general diabetes self-management, with limited structured integration of oral-health education and behavioural approaches.

This study is a multicentre, two-arm randomized controlled trial designed to evaluate the effectiveness and cost-effectiveness of an integrated diabetes-oral health educational intervention based on the Health Belief Model (HBM). The study will recruit 290 adults with T2DM (145 participants per group) from participating diabetes clinics in Oman. Participants will be allocated to either the intervention group or the control group.

Participants assigned to the intervention group will receive six structured, individual HBM-based educational sessions, approximately 30 minutes each, delivered over 12 weeks. The intervention addresses diabetes and oral-health risk awareness; the severity and consequences of periodontal disease in people with T2DM; benefits of glycaemic control and oral hygiene; barriers to oral-health self-care and practical solutions; toothbrushing, interdental cleaning, and self-monitoring skills; and maintenance planning and relapse prevention. Sessions will include structured educational material, individualized advice, and goal-setting. Participants in the control group will continue to receive standard diabetes care and education.

Data will be collected at baseline and at 3, 6, and 12 months, as appropriate for each outcome. The primary outcome is change in HbA1c from baseline to 12 months. Secondary outcomes include periodontal clinical indicators, diabetes and oral-health self-management behaviours, HBM constructs, oral health-related and general health-related quality of life, psychological well-being, diabetes distress, healthcare utilization, and direct medical costs. An economic evaluation will assess the cost-effectiveness of the intervention.

As an exploratory component, participants will undergo periodontal assessment to estimate the prevalence of previously undiagnosed periodontal disease and examine its association with glycaemic control. The study will also explore associations between changes in periodontal status and oral microbiome profiles.

研究衡量的是什么？

主要结果指标

主要结果指标

在临床研究的方案中，对于评估干预/治疗的效果最重要的计划结果测量。大多数临床研究有一项主要结果指标，但有些研究有不止一项。
结果测量
措施说明
大体时间
Change in Glycated Hemoglobin (HbA1c) From Baseline to 12 Months
大体时间：Baseline to 12 months
Change in HbA1c (%) from baseline to 12 months will be used to assess the effect of the intervention on glycaemic control. HbA1c will be measured using blood samples processed in a certified hospital laboratory. The between-group difference in change over time will be evaluated.
Baseline to 12 months

次要结果测量

次要结果测量

在临床研究的方案中，计划的结果测量值在评估干预效果时不如主要结果测量值重要，但仍然值得关注。大多数临床研究有不止一项次要结果指标。
结果测量
措施说明
大体时间
Change in Probing Pocket Depth (PPD)
大体时间：Baseline, 3 months, 6 months, and 12 months
Probing pocket depth will be measured in millimeters (mm) using a periodontal probe at six sites per tooth. Mean probing pocket depth will be calculated for each participant. Change in mean probing pocket depth from baseline will be compared between the intervention and control groups. Lower values indicate better periodontal health.
Baseline, 3 months, 6 months, and 12 months
Change in Diabetes Self-Management Behaviors
大体时间：Baseline, 3 months, 6 months, and 12 months
Diabetes self-management behaviors will be assessed using the Summary of Diabetes Self-Care Activities (SDSCA) questionnaire. The SDSCA assesses the frequency of diabetes self-care activities over the previous 7 days. Items are scored from 0 to 7 days, with higher scores indicating more frequent performance of the assessed self-care behavior. Change in SDSCA scores from baseline will be compared between the intervention and control groups.
Baseline, 3 months, 6 months, and 12 months
Healthcare Utilization
大体时间：From baseline through 12 months
Healthcare utilization will be assessed as the number of healthcare services used by each participant during the study period, including relevant outpatient visits and other healthcare contacts recorded as part of the study. Healthcare utilization will be compared between the intervention and control groups. Higher values indicate greater healthcare resource utilization.
From baseline through 12 months
Change in Oral Health-Related Quality of Life Assessed Using the Oral Health Impact Profile-14 (OHIP-14)
大体时间：Baseline, 3 months, 6 months, and 12 months
Oral health-related quality of life will be assessed using the 14-item Oral Health Impact Profile (OHIP-14). Each item is scored from 0 (never) to 4 (very often), producing a total score ranging from 0 to 56. Higher total scores indicate poorer oral health-related quality of life. The change in total OHIP-14 score from baseline will be compared between the intervention and control groups.
Baseline, 3 months, 6 months, and 12 months
Direct Medical Costs
大体时间：Baseline through 12 months
Direct medical costs associated with healthcare utilization will be estimated from the health-system perspective and reported in Omani Rial (OMR) per participant. Mean direct medical costs over the study period will be compared between the intervention and control groups. Higher values indicate greater healthcare costs.
Baseline through 12 months
