It's not just the size of the waist, but also the size of fat cells that play a major role in determining a women's risk for type 2 diabetes, according to a long-range study by Swedish researchers.
The discovery helps explain why some women of normal weight develop type 2 diabetes, even though they do not have any known risk factors.
"Increased knowledge of the link between enlarged fat cells and the development of type 2 diabetes may give rise to new preventive and therapeutic alternatives. Our research also identifies the ratio waist-to-height, waist circumference divided by body height, as a simple tool that can be used to identify women at risk of developing type 2 diabetes," said Malin Lonn, co-author of the study at Sahlgrenska University Hospital in Gothenburg, Sweden.
The researchers obtained the data for the study as part of the "Prospective Study of Women in Gothenburg," performed in Sweden and started in 1968 by Professor Emeritus Calle Bengtsson.
In the current study, the researchers invited women to free health examinations over the course of 25 years.
