DHA supplementation shows no effect on neonatal metabolic biomarkers in GDM
Última actualización 4 de septiembre de 2026
Key finding
The newborns in the DHA group had higher birth weight z scores (p = 0.02).
This study investigated the effects of docosahexaenoic acid (DHA) supplementation in pregnant women with gestational diabetes mellitus. It found no significant differences in most measured outcomes, except for higher birth weight z scores in the DHA group.

Plain-language summary
What this paper says
A plain-language read of the study’s main message and where it applies.
Study focus
This study investigated the effects of docosahexaenoic acid (DHA) supplementation in pregnant women with gestational diabetes mellitus. It found no significant differences in most measured outcomes, except for higher birth weight z scores in the DHA group.
Clinical relevance
Understanding the effects of DHA supplementation during pregnancy is crucial for managing gestational diabetes and ensuring healthy birth outcomes. While DHA did not improve most metabolic markers, the increase in birth weight z scores may have implications for infant health and development.
Keep in mind
Limited sample size may affect generalizability. Short follow-up period for assessing long-term outcomes. Potential unmeasured confounders influencing results.

La Evidencia Sugiere
- DHA supplementation showed no significant impact on cord blood leptin or adiponectin levels.
- Maternal glycemic control remained similar between DHA and control groups.
- Newborns in the DHA group had higher birth weight z scores (p = 0.02).
A quién se aplica
- Pregnant women diagnosed with gestational diabetes mellitus.
- Women seeking dietary interventions during pregnancy.
Tener en Cuenta
- Results may not apply to populations outside the study's demographics.
- Further research is needed to explore long-term effects of DHA supplementation.
- The study did not measure all potential health outcomes related to gestational diabetes.
Entre Líneas
- Limited sample size may affect generalizability.
- Short follow-up period for assessing long-term outcomes.
- Potential unmeasured confounders influencing results.
