Nutritional status and factors associated with gestational weight gain in the city of São Paulo, 2012 to 2020: a retrospective cohort study.
Article in BMC pregnancy and childbirth, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundGestational weight gain (GWG) is a critical issue related to postpartum health in newborns and mothers. In Brazil, pregnant women's public health recommends monitoring GWG. Therefore, the objective of this study is to evaluate gestational weight gain and associated health factors of pregnant women monitored at Unified Health System (SUS) in the city of São Paulo between 2012 and 2020.
methodsThis is a retrospective cohort study of pregnant women seen from 2012 to 2020 in São Paulo, Brazil. The database used was from the Integrated Health Care Management System related to the Live Birth Information System. Data distribution was assessed using the Kolmogorov-Smirnov test. Comparisons between groups according to weight gain (LWG vs. AWG vs. EWG) were performed using analysis of variance (ANOVA) with Tukey post hoc. Inclusion criteria considered that pregnant women had a recorded initial weight before 13 weeks and up to 15 days before delivery and a single pregnancy. The final database includes 276.220 pregnant women.
resultsThe frequency of women according to initial body mass index (BMI) was 12.004 (4.4%) underweight, 132.049 (48.3%) normal weight, 78.856 (28.8%) overweight, and 50.660 (18.5%) living with obesity. The population consisted of 59.881 (21.9%), 37.217 (13.6%) and 176.471 (64.5%) women with LWG, AWG and EWG, respectively. Weight gain was associated with initial BMI, type of birth, color/ethnicity, marital status, women's age and antenatal care visits.
conclusionThe proportion of pregnant women with inadequate weight gain is high, relating initial BMI, type of birth, color/ethnicity, marital status, women's age and antenatal care visits. Interventions such as nutritional education should be suggested to help achieve adequate GWG.
