Gestational diabetes higher in the summer, says study

A study conducted by researchers at Lund University and Skane University Hospital in Sweden says that pregnant women may be up to 1.5 times more likely to develop gestational diabetes during the summer months.
A total of 11,538 women who had agreed to take part underwent a universally applied standard 75-gramme oral glucose tolerance test, or OGTT, in the 28th week of pregnancy during 2003-2005 in southern Sweden. A total of 487 women were diagnosed with GDM during the study period. The monthly frequency of GDM ranged from 2.9 per cent in March to 5.8 per cent in June.
Speaking about this, the researchers said, Our findings suggest seasonal variations in the glucose concentration and in the proportion of women diagnosed with GDM with a peak in the summer. A positive association with the ambient temperature was demonstrated. A potential mechanism for this relationship is that hypothetically, temperature-induced changes in peripheral blood flow may affect the composition of capillary blood, representing a mixture of arterial and venous blood, explaining the increased glucose levels during the warmer summer months.
