"Having an obese wife increases a man's risk of diabetes over and above the effect of his own obesity level..."

O Men, if you have obese wives then you are in a soup, O women you are safe so says this study

The study’s findings show that for every 5 kg/m2 higher BMI in the wife, the husband's Type 2 diabetes risk was 21 per cent higher when accounting for the man's own BMI.

"Having an obese wife increases a man's risk of diabetes over and above the effect of his own obesity level, while among women, having an obese husband gives no additional diabetes risk beyond that of her own obesity level," said Adam Hulman from Aarhus University in Denmark.

"Our results indicate that on finding obesity in a person, screening of their spouse for diabetes may be justified," Hulman added.
