RESUMEN

Abstract The present systematic review (PROSPERO: CRD42020148630) hypothesizes the association of excessive weight gain during pregnancywith dietary patterns composed of ultraprocessed foods. Thus, the objective was to investigate the association between dietary patterns after analysis and weight gain during pregnancy. The search for articles was performed in nine databases. Two reviewers selected the articles in the databases and extracted from them the data used in the review. Two scales were used to evaluate the quality of the selected studies: New Castle-Ottawa Quality Assessment for cohort-based studies and Appraisal tool for Cross-Sectional Studies (AXIS) for cross-sectional-based studies. In total, 11 studies were identified with sample size variation (n=173-5,733). Women presenting more adherence to healthy and traditional patterns (fruits, vegetables, salads, nuts, and dairy) recorded less excessive gestational weight gain (GWG). Higher intake ofmixed patterns and western patterns rich in ultraprocessed foods were associated with a higher prevalence of excessive GWG (24.48- 55.20%). Gestational dietary patterns a posteriori-derived that have presented ultraprocessed components rich in fat and sugars presented association with high GWG; healthy and traditional dietary patterns were related to better mother-child health conditions, such as adequate GWG.

RESUMEN

BACKGROUND: Dietary patterns can influence maternal and child health outcomes. The study aims to characterize dietary patterns during pregnancy as well as to identify their associations with gestational weight gain (GWG) and anthropometric measurements at birth. METHODS: A minimum sample size of 95 nursing mothers was estimated for this work. Socioeconomic, anthropometric, physical activity, obstetric and food consumption (food frequency questionnaire) data was collected from mothers and their newborns in immediate postpartum (n = 260) at the maternity hospital. Maternal pregestational weight and GWG were self-reported and the neonatal data was obtained from their records. The patterns were derived posteriori by Principal Component Analysis (PCA). Multinomial Logistic Regression and Poisson Regression with Robust Variance were applied. FINDINGS: Four dietary patterns were derived: "pattern 1", characterized by the consumption of meat and eggs, processed meat, vegetables and olive oil; "pattern 2", consisting of sweets, snacks and cookies; "pattern 3", which includes cereals and breads, coffee and tea, and processed fats; and "pattern 4", characterized by soft drinks, tubers and instant noodles. Together, the dietary patterns account for 49.16% of the total variance for food intake. Higher adherence to "pattern 3" was associated with inadequate birth weight (low and excessive birth weight); while greater adherence to "pattern 2" was associated with lower chances of inadequate GWG. CONCLUSION: The dietary patterns presented mixed composition and predominance of ultra-processed foods. They were associated with the investigated outcomes, denoting the importance of strategies to promote healthy eating habits during pregnancy in order to avoid possible complications.
