Maternal and perinatal outcomes in adolescents and women with advanced maternal age.
Article in Revista de saude publica, 2025. 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
objectiveTo analyze the association between age extremes and maternal and perinatal outcomes in births in the state of Rio de Janeiro, Brazil.
methodsData from the Birth in Brazil II: National Survey on Abortion, Delivery, and Birth (2021-2023) were used. A total of 1,734 postpartum women were included, with live or stillborn newborns, interviewed in the immediate postpartum period. Information was obtained from interviews, clinical records, and prenatal cards. Multiple logistic regression was carried out to evaluate associations between maternal age and outcomes, having women aged 20-34 years as reference.
resultsDelivery in adolescents represented 10.1% of the participants, while women with advanced maternal age (AMA ≥ 35 years) corresponded to 18.0%. Adolescents were less likely to receive guidance as to reference maternity hospital (odds ratio - OR = 0.68) and to have a companion at all times (OR = 0.77), in addition to presenting lower prevalence of gestational diabetes (OR = 0.26). In turn, women with advanced maternal age were more often guided on reference maternity hospitals (OR = 1.46) and presented a higher risk of gestational hypertension (OR = 1.78), gestational diabetes (OR = 1.87), placental abruption (OR = 3.30), and severe maternal morbidity (OR = 1.84). In perinatal outcomes, adolescents had a higher risk of perinatal death (OR = 4.52) and spontaneous early-term delivery (OR = 1.47); however, there was a lower probability of early-term delivery by obstetric intervention (OR = 0.48). Newborns of women with advanced maternal age presented higher risk of 5-minute Apgar index < 7 (OR = 3.05) and lower chance of congenital syphilis (OR = 0.34).
conclusionsAdolescents were provided worse care compared to adults, while women with advanced maternal age presented a higher frequency of age-related complications. These results highlight the need for special care, particularly considering the increase in deliveries in women with advanced age.
