Choline in Adolescent Pregnancy: The Impact on Fetal Brain Development and Long-Term Cognitive Outcomes of Offspring.
Review in Medicina (Kaunas, Lithuania), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Pregnancy in adolescence represents a major nutritional challenge, with competing demands between maternal development and fetal growth. Choline is the essential nutrient with a critical role for fetal brain development and exhibits distinct metabolic patterns in pregnant adolescents aged 15-19 years compared to adult pregnant women. This narrative review examines the specific impact of choline status on fetal neurodevelopment in adolescent pregnancies. A comprehensive literature review was conducted using PubMed and Web of Science databases from 2000 to 2025, focusing on choline metabolism, placental transport mechanisms, and neurodevelopmental outcomes in adolescent pregnancy. Adolescent pregnant women demonstrate reduced choline clearance (0.8 ± 0.2 vs. 1.2 ± 0.3 mL/min/kg), decreased choline kinase activity (25-30% reduction), and reduced placental transporter expression (CTL1 reduced by 15-20%) compared to adults. These metabolic differences result in maternal-fetal competition for limited choline resources, potentially compromising fetal brain development during critical neurodevelopmental windows. The consequences include increased risk of neural tube defects, altered hippocampal development, and long-term cognitive impairments in offspring. Adolescent pregnancy creates a unique biochemical environment that may predispose to choline deficiency with lasting neurodevelopmental consequences, and current supplementation guidelines do not address adolescent-specific needs, pointing out the urgent requirement for appropriate age recommendations and targeted interventions to optimize maternal and fetal outcomes in this vulnerable population.
