Association between ultra-processed food exposure and gestational diabetes mellitus by diet balance index for pregnancy in Chinese women.
Article in Asia Pacific journal of clinical nutrition, 2026. 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
BACKGROUND AND
objectivesThis study aims to investigate the impact of ultra-processed food (UPF) intake and the Chinese Diet Balance Index for Pregnancy (DBI-P) index on cesarean section rates and neonatal weight among women with gestational diabetes mellitus (GDM). METHODS AND STUDY
designThis study was a retrospective cohort study involving 279 GDM patients. We have collected dietary data, pregnancy information, and calculated UPF intake and the Chinese Diet Balance Index for Pregnancy (DBI-P) index. The impact of UPF exposure and dietary factors on low birth weight and macrosomia was analyzed using logistic regression.
resultsThis study revealed widespread insufficient consumption of several food groups among the GDM population. Specifically, compared with the UPF non-exposed group, the UPF-exposed group had a significantly higher rate of insufficiency in vegetables (Z = -4.94, p <0.001) and dairy products (Z = -2.28, p = 0.007), but a lower intake of plant oils (Z = -2.16, p = 0.03). After adjusting for several factors, the logistic regression results showed that UPF exposure was a risk factor for cesarean section (OR = 1.74, p = 0.046). Moreover, GDM patients who were overweight or obese before pregnancy faced a higher risk of a cesarean section when exposed to UPFs (OR = 4.13, 95%CI(1.35, 12.6)).
conclusionsPatients with GDM showed an unbalanced dietary intake pattern, which was more pronounced in the group with higher exposure to UPFs. However, prenatal UPF exposure did not significantly affect the patients' oral glucose tolerance test (OGTT) results. Nonetheless, excessive UPF consumption during pregnancy may increase the risk of cesarean section.
