About
Juliana dos Santos Vaz is a nutritional epidemiologist whose research focuses on the role of essential fatty acids in maternal and child health, particularly during pregnancy. Her work has been instrumental in understanding how diet, lifestyle, and body composition influence the serum levels of omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) in pregnant women. In her highly cited 2014 study, she demonstrated that a food frequency questionnaire can serve as a reliable indicator of serum PUFA composition in early pregnancy, while also revealing that body mass index significantly modifies this relationship. Her 2015 prospective cohort study further showed that shorter inter-pregnancy intervals and unhealthy lifestyle factors are inversely associated with changes in essential n-3 fatty acids during pregnancy, highlighting critical modifiable risk factors for maternal nutritional status. With over 48 citations across her most prominent papers, Vaz’s research provides valuable insights for prenatal nutrition guidelines and underscores the importance of addressing both dietary patterns and sociodemographic determinants to optimize fatty acid status in pregnant women. Her work continues to inform interventions aimed at improving maternal and neonatal outcomes.
