Inflammation Clinical Trial
Official title:
Calcium and Vitamin D Supplementation and Periodontal Therapy for Improving Metabolic and Inflammatory Profile Among Pregnant Women: a Feasibility Trial (THE IMPROVE TRIAL)
The improvement of maternal and child health remains a key issue in global health. Production and improved accessibility of healthy and nutrient-rich milk-based products could potentially tackle health and nutrition inequalities in low-income countries. This study will assess the acceptability of a multi-component intervention, including provision of calcium/vitamin-D fortified milk and periodontal therapy (PT), for improving maternal periodontal health and metabolic and inflammatory profiles. The IMPROVE trial is a feasibility randomised controlled trial (RCT) with parallel qualitative process evaluation. The target population is low-income, pregnant, Brazilian women, with periodontitis, who have not seen a dentist in the last 6 months. A series of focus group discussions and interviews with the target population will be conducted to identify key barriers and enablers to adoption and implementation of the intervention in prenatal clinics in Rio de Janeiro/Brazil. Participants will be allocated to 4 groups: 1) early PT (during pregnancy) plus fortified milk; 2) early PT plus plain milk; 3) delayed PT (after delivery) plus fortified milk; 4) delayed PT plus plain milk. The final results will contribute to the understanding of the significance of calcium and vitamin D for short and long-term health and the occurrence of diseases, as well as to inform the current global debate on vitamin-D supplementation and fortification policy.
