The improve trial: This is a viability clinical trial in partnership with the University of Westminster (London), Parker Institute (Denmark), Rio de Janeiro State University (UERJ) and Instituto Fernandes Figueiras (FIOCRUZ). The effectiveness and cost-effectiveness of a multicomponent intervention that addresses the fortification of calcium and vitamin D milk and periodontal therapy in oral health and the improvement of the metabolic and inflammatory status of low-income pregnant women with periodontitis are being investigated. Women are evaluated in the 2nd and 3rd trimesters of gestation and postpartum. In addition, vitamin D will be quantified in infants with blood collected in the Guthrie test.
Bioactive compounds of breast milk and association with maternal health and child development: it is a cohort of pregnant women and their children. The objective of this study is to evaluate the composition of human milk in terms of microbiota, immunological compounds and oligosaccharides and its association with maternal outcomes, as well as the growth and development of the child up to one year of age. Socio-demographic information, nutritional status, clinical and biochemical parameters, mental health, expenditure and level of physical activity will be collected. The entire project will be carried out through collaboration with primary care. The project has a partnership with Columbia University (United States).
The 3rd project is scheduled to begin recruitment and data collection in October this year:
MILQ (Mothers Infants and Lactation Quality): International multicenter study in five countries: Brazil, United States, Denmark, Bangladesh and The Gambia. This project is in the phase of questionnaires and protocols reviews with prediction for the beginning of the capture of the pregnant women in October of the current year. It aims to establish reference values for micronutrient concentrations in human milk based on data from women with adequate nutritional status and not supplemented. This is a cohort study with four follow-up waves with onset in the immediate postpartum and performed up to 9 months of the child's life. Socio-demographic, reproductive and lifestyle information, mental health and child cognitive development will be collected, as well as biological samples such as feces, urine, blood and saliva. This study is funded by the Bill & Melinda Gates Foundation and the coordinating center is located in the United States at the United States Department of Agriculture (USDA).
The 4th ongoing study is the validation of the growth curves proposed in the Intergrowth-21st for the Brazilian population. The main goal of this study is to develop and evaluate the applicability of new recommendations for gestational weight gain from the Intergrowth-21st curves for women classified with eutrophy or overweight according to pre-gestational body mass index for future implementation in the Unified Health System. An additional objective is to suggest recommendations for gestational weight gain for the first trimester of pregnancy and for women with low weight and pre- not contemplated in the Intergrowth-21st curve.

The evaluation of the nutritional status of individuals and communities is indispensable in studies that aim to understand the health and life conditions of a population. In this way, the Institutes of Research in Population Studies in Nutrition - GIPEPON - integrates professionals engaged in projects that have in common methodologies with the proposal of diagnostic investigation of the nutritional situation of the Brazilian population, including anthropometric, biochemical, clinical, dietetic and socioeconomic conditions. The group concentrates its research activities in Nutritional Epidemiology that compose one of the five lines of research of the Graduate Program in Nutrition of the INJC, developing studies on the nutritional status of individuals and communities and their determinants; food consumption of population groups and their determinants; nutrition and health of children and adolescents; obesity and eating disorders; food and nutritional security and studies on poverty and its repercussions on the nutritional status of the Brazilian population. GIPEPON is registered in the CNPq Research Group Directory.
