Impact of nutrition counseling on dietary improvements, glycemic control, and neonatal outcomes in pregnant women with pregestational diabetes mellitus: an electronic medical charts analysis study in a tertiary medical center.
Article in BMC pregnancy and childbirth, 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
backgroundPregnant women with pregestational diabetes mellitus (PDM) are at higher risk of adverse maternal and neonatal outcomes, including preterm birth and macrosomia. Nutrition counseling plays a critical role in improving glycemic control; however, its effectiveness in pregnant women with PDM in Taiwan has not been fully evaluated. This study aims to evaluate the effects of nutrition counseling on dietary intake, glycemic control, gestational weight gain (GWG), and neonatal outcomes in pregnant women with PDM.
methodsWe conducted a retrospective review of electronic medical records from 2012 to 2022 at a tertiary medical center in Taiwan. A total of 106 pregnant women with type 1 or type 2 diabetes were included, of whom 48 received nutrition counseling (NC group) and 58 did not (Non-NC group). Dietary records, blood glucose, and pregnancy outcomes were analyzed.
resultsThere were no significant differences between the groups with and without nutrition counseling in terms of gestational weight gain, preterm birth rate, or the incidence of macrosomia. Nutrition counseling significantly increased the intake of fruits and whole grains and improved dietary fiber consumption (p < 0.001). After the intervention, the proportion of women consuming < 175 g of carbohydrates decreased from 55.3% to 34.2%. Among 24 participants with pre- and post-intervention blood glucose data, fasting glucose and HbA1c levels decreased significantly (p < 0.001 and p = 0.001, respectively). Greater improvements were observed in those receiving multiple counseling sessions.
conclusionsNutrition counseling enhanced fiber intake by increasing the consumption of fruits, vegetables, and whole grains. Repeated counseling sessions significantly improved glycemic control, although no significant changes were observed in pregnancy outcomes. These findings underscore the clinical value of integrating structured nutrition counseling into routine prenatal care and highlight the need for larger prospective studies to confirm its impact on pregnancy outcomes.
