About this study
Official title: Effectiveness of a Culturally Tailored Medical Nutrition Therapy for African Patients With Type 2 Diabetes: The Objectif Santé Diabète Benin (OSanDiaBé) Trial
The clinical trial aims to assess the effectiveness of the Objectif Santé Diabète Benin (OSanDiaBé), a culturally tailored medical nutrition therapy (MNT), in enhancing diabetes management and nutrition choices. The investigators hypothesize that participants receiving OSanDiaBé will demonstrate greater improvements in dietary adherence and greater reductions in HbA1c at 6 months compared with those receiving usual care. The investigators further hypothesize that these improvements will be maintained at 12 months following the end of active intervention contact.
Read the detailed description
This study is a 12-month, parallel-group, randomized controlled trial involving individuals diagnosed with type 2 diabetes. Participants will be randomly assigned in a 1:1 ratio to either (1) usual care (wait-list control group) or (2) nutrition counseling with group-based education (intervention group). The intervention group will receive the OSanDiaBé resource package, which includes a workbook, and an Eating Plan based on the 4-A framework of food security. They will participate in four individual home sessions and eight group sessions in the first six months, with no contact between months six and twelve. The primary outcome will be the change in HbA1c levels, while secondary outcomes will include lipid profile, anthropometric measures, dietary adherence, diabetes self-efficacy, and diabetes-related quality of life. All outcomes will be assessed at baseline, 3, 6, and 12 months.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.

This MNT intervention combines evidence-based menu plans based on the 4A framework of food security with individual nutrition counseling and group diabetes education.
| Study group | Role | What they receive |
|---|---|---|
| OSanDiaBé intervention | Experimental | The Objectif Sante Diabète Bénin (OSanDiaBé) intervention group will participate in four individual home sessions and eight group sessions in the first six months, with no contact between months six and twelve. They will receive the OSanDiaBé resource package, which includes a workbook and an Eating Plan based on the 4-A framework of food security. Receives: Behavioral: A culturally tailored medical nutrition therapy |
| Individual standard care | No intervention | The Individual standard care arm will be a wait-list control group who will receive standard care, including blood glucose management and general lifestyle advice, and will access the OSanDiaBe program at the end of the intervention for equitable treatment. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Hemoglobin A1C (HbA1C)
A hemoglobin A1C (HbA1C) test is a blood test that shows the average level of blood glucose over the past two to three months.
Measured: HbA1c will be assessed at baseline, 3, 6, and 12 months.
Secondary outcomes (8)
Adherence to dietary recommendations
Dietary adherence will be assessed using the modified UK Diabetes and Diet Questionnaire (UKDDQ), which consists of 22 items on dietary patterns. Responses indicate food consumption frequency and are coded as follows: A=5 (healthy), B=4 (healthy), C=3 (less healthy), D=2 (less healthy), E=1 (unhealthy), F=0 (unhealthy). Final scores range from 0 to 5, with higher scores indicating better dietary habits.
Measured: Dietary adherence will be assessed at baseline, 3, 6, and 12 months.
Weight
Weight will be measured in kilograms to the nearest 0.1 kg with a standard weighing scale (Hana model, China) while ensuring the participants wear light clothing and no shoes.
Measured: Weight will be assessed at baseline, 3, 6, and 12 months.
Height
Height will be measured with a stadiometer to the nearest 0.1 cm.
Measured: Height will be assessed at baseline, 3, 6, and 12 months.
Body mass index
The BMI (Body Mass Index) will be calculated using the formula: weight (kg) divided by height (m) squared. WHO classifications will be used for adult BMI: underweight (under 18.5 kg/m2), normal weight (18.5 to 24.9), overweight (25 to 29.9), and obese (30 or more).
Measured: BMI will be assessed at baseline, 3, 6, and 12 months.
Waist circumference
The waist circumference will be measured at the umbilicus using a non-elastic tape measure while the participant stood upright, recorded in centimeters.
Measured: Waist circumference will be assessed at baseline, 3, 6, and 12 months.
Blood pressure
The blood pressure will be measured with a sphygmomanometer.
Measured: Blood pressure will be assessed at baseline, 3, 6, and 12 months.
Lipid profile
Lipid profile will include triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C).
Measured: Lipid profile will be assessed at baseline, 3, 6, and 12 months.
Behavioral outcomes
The investigators will use the Academy's Evidence-Based Nutrition Practice Guidelines (AEBNPG) for MNT to track behavioral changes in meal planning, food preparation, and physical activity, rating adherence on a scale of 1 (never) to 5 (consistently).
Measured: Behavioral outcomes will be assessed at baseline, 3, 6, and 12 months.
