Summary

Researchers at KK Women's and Children's Hospital are studying whether the timing of meals and snacks during pregnancy relates to blood sugar levels. About 300 pregnant women in Singapore, between 18 and 21 weeks gestation, will keep food diaries and use a food record app. The team will compare eating patterns, including night eating, with results from standard oral glucose tolerance tests and insulin measurements.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If a link emerges between night eating and poorer glucose tolerance, it could shape simple timing advice for pregnant women and help spot those at higher risk of gestational diabetes earlier.
What could go wrong
This is an observational study, so it can show associations but not prove that eating at night causes blood sugar problems. Findings in Singapore may not apply to other populations, and many other factors affect glucose during pregnancy.
