The diet quality of pregnant women is associated with several maternal and fetal healthoutcomes. The Diet Quality Index Adapted for Pregnant Women (IQDAG), previouslydeveloped for Brazilian pregnant women, presents nine components: vegetables, legumes andfresh fruits in portions / 1000 kcal; iron, folate, calcium, omega 3 and fiber, and thepercentage of energy from the consumption of ultra-processed foods as a moderatingcomponent. The objective of the present study will be to investigate the relationship betweenIQDAG and birth weight. It is a prospective cohort that will employ data from a previouscross-sectional study, conducted among 785 adult pregnant women attended by SUS in thecity of Ribeirão Preto-SP, complemented with the data collection of pregnant women andnewborns that will be performed in the systems of health information of the municipality ofRibeirão Preto: Pregnancy Monitoring System (SisPreNatal) and Information System for LiveBirths (SINASC). Pregnant women diagnosed with gestational diabetes mellitus, cases ofprematurity, and with incomplete data will be excluded. Birth weight will be classified asadequate, low birth weight, macrosomia, small for gestational age and large for gestationalage. The diet was estimated using two 24-hour dietary recalls and a food frequencyquestionnaire previously validated for pregnant women. The usual intake was obtained usingthe Multiple Source Method. The relationship between the IQDAG score and the birth weightwill be investigated using adjusted linear, logistic and / or multinomial regression models,depending on the characteristics of the data. Data analysis will be performed using the SPSSsoftware and the level of significance adopted will be in the value of p < 0.05. (AU)
