Relationship between glycaemic and physical activity and birthweight
There was a significant positive relationship between 3 h postprandial blood glucose (at 35 weeks) and birth weight (r = 0.48; p = 0.05). There was a significant moderate, positive correlation between standing time (at 35 weeks) and birth weight (r = 0.51; p = 0.02). There was also a significant, moderate negative correlation between sitting bouts > 30 min (at 35 weeks) and birth weight (r = -0.53; p = 0.02). There was no significant relationship between 28-week postprandial glucose, stepping time, sitting time, standing time, or sitting bouts > 30 min and birth weight.
