Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• 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.

  HbA1c will be assessed at baseline, 3, 6, and 12 months.

Secondary Outcomes (8)

• Adherence to dietary recommendations

  Dietary adherence will be assessed at baseline, 3, 6, and 12 months.

• Weight

  Weight will be assessed at baseline, 3, 6, and 12 months.

• Height

  Height will be assessed at baseline, 3, 6, and 12 months.

• Body mass index

  BMI will be assessed at baseline, 3, 6, and 12 months.

• Waist circumference

  Waist circumference will be assessed at baseline, 3, 6, and 12 months.

Study Arms (2)

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.

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.

Interventions

A culturally tailored medical nutrition therapy BEHAVIORAL

This MNT intervention combines evidence-based menu plans based on the 4A framework of food security with individual nutrition counseling and group diabetes education.
