Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A novel line of research has emerged, suggesting that synchronizing the timing of food intake with body's circadian rhythms or day-night cycle has metabolic implications. Eating at the inappropriate time can disrupt circadian system which might induce metabolic perturbations, including glucose abnormalities. Recent evidence showed that circadian timing of eating was associated with glucose regulation in pregnant women. However, little is known about night-eating pattern during pregnancy, particularly the influence of nocturnal snacking on glycaemic control.

This cross-sectional study aims to recruit 400 pregnant women at 18-21 weeks' gestation. The investigators will assess maternal dietary intake, monitor 24-hour activity-rest pattern and light-dark exposure, and measure glucose and insulin profiles during the second trimester of pregnancy. Maternal socio-demographic status, lifestyle characteristics, health conditions and pregnancy outcomes will be asked through interview or retrieved from medical notes.

This study allows understanding the importance of circadian eating pattern, which is a modifiable behavior, in glycaemic control during pregnancy, and help to provide evidence for developing nutritional guidelines which can ameliorate metabolic health for mothers.
